Data current as of 30 October 2026, checked against the Gambling Commission’s public register and each operator’s own terms.

An “enhanced odds” offer is the front of the shop window. A bigger number next to a team. A “bet £10, get £40 in free bets” headline. A price boost on a Premier League accumulator that quietly doubles in price for new customers only. Every UK sportsbook now runs one. The Gambling Commission’s rules tightened the window in January 2026, so the headline is closer to the truth than it was, and the gap between the headline and the offer’s real cost is the part of this page worth reading.

The point of this page is what an enhanced odds offer actually costs. Not what it pays when it wins. Not the marketing word the bookmaker chose for it. The turnover the bonus needs, the minimum price the qualifying bet must clear, the deadline that starts running the moment the free bet lands in an account, and the cap on how much a single win can return. Ten UK bookmakers are reviewed below, and the comparison table that follows each cluster of rules is what makes the difference between two of them visible. A £40 free bet that expires in seven days is not the same offer as a £40 free bet that expires in thirty; a price boost that pays cash is not the same offer as one that pays free bet credit; an enhanced accumulator with a maximum return of £1,000 is not the same offer as one with no stated ceiling.

The framework is the Gambling Commission’s new promotion rules, in force since 19 January 2026. Two of them matter for every offer on this page. First, any wagering requirement attached to a bonus is capped at 10x. A £10 bonus can never require more than £100 of betting turnover before it can be withdrawn. A £50 bonus is capped at £500. The cap resets the calculus for every sign-up offer on a UK site, and the operator reviews below read the cap into each one of them. Second, mixed-product promotions are banned. An offer that requires a customer to bet on football to claim free spins, or to deposit money that must be played on a slot before it can be withdrawn as cash, is no longer lawful. The clause quietly outlaws the kind of cross-sell that propped up welcome packages for a decade. Free bets that carry no wagering condition sit in a grey zone: research has not established whether the cap applies to them, so this page treats it as a question the answer is not known to.

Why a bigger number is rarely a bigger value

An “enhanced odds” headline does one job — it makes the price next to one outcome larger than the market price. The bookmaker pays for that increase out of margin, which means the rest of the prices on the coupon are slightly worse, or the free bet that comes with the enhanced price is harder to clear than a normal one would be. The arithmetic that decides whether the boost is worth taking is the same arithmetic that decides every other offer on the page: what does the qualifying bet cost, what does the free bet return on average, and how long does the bettor have to do it in. A 4/1 boosted to 6/1 on one football match is, on its own, a real increase. The trade comes in the rest of the coupon and the free bet that follows.

Three numbers decide the cost of any enhanced odds offer. The wagering multiple, the minimum odds, and the expiry. The wagering multiple is how many times the bonus must be turned over before it can be withdrawn as cash. The minimum odds are the price the qualifying bet must beat — anything shorter does not count. The expiry is the deadline by which the free bet must be used; after that it is gone. The arithmetic that follows is simple and unforgiving: a 10x turnover on a £10 free bet is £100 of betting; at a 5% market margin that is £5 of expected cost before the free bet has paid a penny; a 7-day expiry turns it from a weekend task into a Tuesday-night panic.

The size of the free bet is the number on the front. The cost of the free bet is the number that follows. A £30 free bet that costs £3 to clear is cheap. A £30 free bet that costs £9 to clear is expensive at half the headline. The market margin of the sport and the bet type is the lever — horse racing margins run higher than football, accumulators carry more margin than singles, in-play prices are wider than pre-match. The same £30 free bet staked on a five-fold accumulator is the same stake at a higher margin, and the cost of clearing it goes up with the coupon.

How the 10x cap reshapes the table

The 10x cap is the first thing that matters about any bonus on a UK-licensed site in 2026, because it draws a hard line at the upper end of the cost. Pre-2026, a £10 bonus could come with a 50x or 60x turnover requirement; under the cap that is no longer allowed. The cap is the Commission’s judgement that the player’s stake in the deal should not be a tax on the bonus itself. The arithmetic in the worked example later on this page assumes the cap is the binding constraint, not the operator’s own terms.

There is no published lower limit. An operator may still set a 3x or 5x turnover, and a 1x turnover is legal — every bookmaker reviewed here has at least one offer that comes with no wagering condition at all, paid as cash. The cap is the ceiling, not the floor. The shape of the market after January 2026 is offers at the cap, offers well below the cap, and offers that pay cash with no playthrough at all, in roughly equal number. A reader comparing them should look for the lowest multiplier, the longest expiry, and the highest minimum odds: those are the dimensions on which an offer’s real value moves.

The cap is paired with the mixed-product ban. An offer that asks a customer to bet on football in order to claim a casino bonus, or to play slots in order to unlock a free bet, is no longer permitted at a UK-licensed site. The clause does not ban each offer on its own; it bans the combination. A sportsbook can still give a £20 free bet to a new sports customer and a £10 casino bonus to a new casino customer. What it cannot do is tell the sports customer that a casino bet is what unlocks the free bet. The clause is a quiet piece of consumer protection, and it makes a casino-style welcome package a much rarer thing at a UK sportsbook.

A worked example: what clearing a £20 free bet actually costs

The worked example is built from Coral’s welcome offer and the 10x cap in force since 19 January 2026. The arithmetic is the heart of the page, and the conclusion is a band rather than a single figure because the cost depends on the market the bettor wagers the free bet on.

The qualifying bet is £20 at minimum odds of 2.0 (1/1). Once settled, £40 of free bets are issued, expiring seven days after issue. The headline is “Get £40 in free bets when you bet £20.” The wagering requirement is not stated in Coral’s terms, so under the Commission’s cap it cannot exceed 10x. A £40 free bet at 10x turnover is £400 of betting. A £40 free bet at 5x turnover is £200 of betting. The cost of clearing the offer scales with the multiple and the market margin.

Plug in two reasonable bookmaker margins. At a 5% margin on a typical football market, £400 of turnover costs £20 in expected loss; £200 of turnover costs £10. At an 8% margin on a typical horse racing market, £400 of turnover costs £32; £200 of turnover costs £16. The expected cost of clearing the offer, before the free bet has won anything, sits in a band from roughly £10 to £32 depending on the multiple and the market. The free bet’s expected value, on the same markets and on the same assumptions, is the stake multiplied by the odds minus one and divided by the odds — for a £40 free bet at 2.0, that is £20 of expected return, less the cost of clearing the offer.

The conclusion is that the offer is worth taking in roughly half the cases: where the market margin is low and the wagering multiple is at or near the floor. It is worth passing over where the multiple is at the cap and the market margin is at the high end, because the cost of clearing the offer eats most of the free bet’s expected value. The figure is an estimate, not a guarantee. A punter who backs an outsider at 20/1 turns the offer positive; a punter who backs a heavy favourite at 1/10 turns it negative on a single bet. The arithmetic holds in the long run; a single bettor on a single coupon can land anywhere inside the band or outside it.

The free bet stake is not paid back with a winning free bet. That is the part of the offer that always catches out a first-time customer, and it is the part the headline never mentions. A £40 free bet at 2.0 returns £80 of profit, not £120 of return. The £40 of stake is the bookmaker’s. The punter keeps the profit and the bookmaker keeps the stake, and that is how every free bet on every UK-licensed site is built.

The ten UK bookmakers, ranked by what their offers cost

A comparison of ten UK-licensed bookmakers, ordered by what their sign-up offers cost the punter rather than by the size of the headline. The framework is the 10x wagering cap, the mixed-product ban, the minimum odds, the expiry, and whether the free bet stake is paid back. The table is the headline test: each brand’s offer on one row, the cost the terms imply on the next.

The spread of welcome offers is wider than the spread of headline numbers. A £40 free bet at Unibet and a £40 free bet at Coral are not the same offer: Coral’s expires seven days after issue, Unibet’s expires within seven days of issue, and the difference between “within” and “after” is the difference between seven days of grace and seven days of calendar. BetMGM splits the free bet into four £10 tokens, two of them football accumulators of four or more selections and two of them sports multiples of two or more — a structure that pins the punter into specific market types and pushes the effective margin of the offer higher than a flat £40 token would. Smarkets, via its SBK sportsbook, asks the qualifying bet to clear at minimum odds of 3.0, which is twice the floor at Coral and Unibet, and offers £60 in free bets in return; the higher qualifying price is the trade.

Two brands in the table do not advertise a sign-up offer. Betfred’s app lists new-customer free bets and free spins subject to terms without a headline number; the offer is in the app, not on the home page. Star Sports lists its Bet Boosts, Daily Specials and Weekend Enhanced Boosts without a new-customer headline. The point of including both is that “no headline offer” is itself an answer to the comparison: a bookmaker that competes on odds and features rather than on a welcome bonus is a different proposition to the one that competes on the £40 free bet. Betfred’s offer mechanics are described in the app; Star Sports’ offer mechanics are described in its own terms. A punter who prefers an enhanced price on every coupon over a one-off sign-up bonus is the customer those two are built for.

The licence column is the table’s anchor. Every brand is on the Gambling Commission’s public register, every licence number is verifiable on the register, and the licence holders are the legal entities that hold the right to take bets in Great Britain. The same register is the place to check a brand before signing up: a licence number that does not resolve on the Commission’s site is a brand that should not be depositing money with, full stop.

The fundamentals: how an enhanced odds offer is actually built

An enhanced odds offer is one of three things, and the marketing often blurs them. A price boost is a higher price on one outcome of one event, paid in cash if it wins. A free bet is a token that lets the punter place a bet without risking their own money, with the stake not paid back if the bet wins. A sign-up offer is a combination of the two — a qualifying bet that earns free bets — and the terms describe how the parts fit together. Each of the three has a different cost profile and a different decision rule.

A price boost is the simplest. The bookmaker increases the price on one outcome, the punter backs it, and the stake returns at the boosted price if the selection wins. There is no wagering requirement, no expiry (the bet settles at the event), and the stake is paid back. The cost of the boost to the bookmaker is the difference between the boosted price and the market price, paid out only on a win. The cost of the boost to the punter is the opportunity cost of placing the bet at one bookmaker rather than another, and the chance the bookmaker’s price is worse on every other selection on the coupon. A boost that lifts 4/1 to 6/1 on a single football match is, on its own, a real offer; the trade comes in the rest of the price.

A free bet is more complex. The bookmaker credits a token — say £20 — to the punter’s account, and the punter uses the token to place a bet. If the bet wins, the punter keeps the profit but not the £20 stake. If the bet loses, the punter loses nothing further. The cost of the free bet to the bookmaker is the punter’s expected profit, which is the stake multiplied by the odds minus one and divided by the odds — for a £20 free bet at 3.0, that is £13.33 of expected cost. The cost of the free bet to the punter is the chance the bet loses, multiplied by the opportunity cost of the stake not being their own. The arithmetic in the worked example above is the same arithmetic applied to a sign-up offer’s free bet, with the qualifying bet as a sunk cost on the front of the deal.

A sign-up offer stitches the two together. The punter deposits, places a qualifying bet at a minimum price (typically 1/2, 1/1 or 3.0), and earns free bets once the qualifying bet has settled. The free bets may be paid as a single token or split across several (BetMGM splits £40 into four £10 tokens; Coral pays £40 as a single token). The free bets may be limited to specific market types (BetMGM’s two football accas and two sports multiples; a generic Unibet free bet usable on any market). The free bets may carry a wagering requirement, a minimum price, and an expiry. The shape of the offer is the shape of those three conditions: a long expiry, a low minimum price, and no wagering requirement is one offer; a seven-day expiry, a high minimum price, and a 10x turnover is another. The headline number is the front; the conditions are the back.

The mechanics of price boosting, in practice

Price boosts come in two flavours: a one-off boost on a specific event (typically football), and a daily menu of boosts on selected events. Bet365’s Super Boosts sit in the first category — a handful of enhanced prices promoted across the home page each day, paid as cash if the selection wins. William Hill’s Football Acca Boost sits in the second, paying a percentage boost on accumulators of two or more legs: 3% on a double, climbing to 200% on twenty or more legs, with a maximum boost of £10,000 per online bet and the offer running until 30 May 2027. Spreadex’s Acca Boosts give a cash boost from 5% up to 100% on football accumulators of three or more selections, depending on the number of legs. Unibet runs daily Uniboosts, plus Best Odds Guaranteed on horse racing and Cash Out on thousands of markets.

The decision rule is the same in every case. A cash boost on an accumulator is a real increase in the payout, paid in cash, and the only cost is the chance the accumulator’s legs do not all win. A boost that pays in free bet credit is a different proposition, because the free bet’s value is itself reduced by the no-stake-returned rule and the possible expiry and wagering conditions. A maximum boost of £10,000 is a ceiling the punter is unlikely to brush against; a minimum bet of £5 and minimum odds of 1/5 on each leg is a floor that excludes almost nothing. A bettor who builds accumulators regularly and at modest stakes is the customer an Acca Boost is built for; a bettor who places singles is paying for a feature they do not use.

Free bets, the stake rule, and the expiry

The free bet stake is not paid back with the winnings. That is the rule at every UK-licensed bookmaker reviewed here, and the rule is what turns a £40 free bet from a £40 stake into a token worth less than its face value. A £40 free bet at odds of 3.0 returns £80 of profit, not £120. The punter’s bank is up by £80; the bookmaker’s bank is up by £40. The punter who thought the free bet was worth £120 has overestimated the offer by £40.

The expiry is the second condition. Coral’s £40 in free bets expires seven days after issue; BetMGM’s four £10 free bets are valid for seven days; Unibet’s free bets expire within seven days of issue; BoyleSports’ free bet from the welcome offer is the same shape, seven days from credit. Sky Bet credits its welcome offer as three £10 tokens, each following the same rule. The seven-day window is the norm at the top of the market, and a punter who does not use the free bet inside the window loses the offer. The 48-hour window at Smarkets’ SBK sportsbook is the outlier — the £60 in free bets lands within 48 hours, but each token’s expiry is the same shape as the rest of the industry.

The minimum price on the free bet is the third condition. QuinnBet’s free bets can be used on any market at odds of 1/2 (1.5) or greater, with maximum odds of 50/1; straight accumulators are allowed but Trixies, Patents and Yankees are not. The maximum-odds cap is the clause that stops a punter putting a free bet on a 100/1 outsider, and the excluded multi-bet types are the clause that stops a punter from chaining seven small-priced selections into a long-odds each-way combination. The two clauses together define the offer’s range: from 1/2 to 50/1, singles and accumulators, but not the full multi-bet menu. A punter who wants to use the free bet on a Lucky 15 is not the customer QuinnBet is building the offer for.

The statute: who regulates enhanced odds in Great Britain

The Gambling Commission licenses the whole commercial market in Great Britain under the Gambling Act 2005, which covers England, Scotland and Wales; Northern Ireland sits outside the Act and is governed by its own older law. The Commission is a non-departmental public body sponsored by the Department for Culture, Media and Sport. Every UK-licensed sportsbook on this page is on the Commission’s public register, and the register is the only test of whether a brand holds a licence. Since the Gambling (Licensing and Advertising) Act 2014, an operator whose remote facilities are used in Great Britain needs a Commission licence wherever it is based; a Curaçao, Maltese or Gibraltar licence is not a substitute. Several of the brands reviewed here are run from Gibraltar — Unibet by Platinum Gaming Limited, Betfred by Petfre (Gibraltar) Limited — and they hold GB remote licences from the Commission, which is the only licence that matters for the punter sitting in London, Manchester or Glasgow.

The framework for enhanced odds offers sits inside the Licence Conditions and Codes of Practice (LCCP) and the Commission’s social responsibility code. The promotion rules in force since 19 January 2026 are the headline change: a 10x cap on wagering requirements, a ban on mixed-product promotions, and a separate set of conditions on how offers are marketed. The Commission is also the body that licenses specific categories — remote general betting standard (real events) is the typical category for a sportsbook, remote general betting standard (virtual events) is the category for virtual sports, remote general betting limited is a smaller-stakes category, remote pool betting covers pool products, and remote betting intermediary is the category for betting exchanges. Matchbook and Smarkets, both on this page, are licensed as betting intermediaries; the rest are licensed as general betting standard. The category is the legal frame for what markets the operator can offer and how those markets are run.

Financial spread betting is a different regime. Spreadex is regulated by the Financial Conduct Authority for spread betting and by the Gambling Commission for fixed-odds betting, and the company states that spread betting losses can exceed the deposit. The two licences do different jobs: the FCA regulates the financial product, the Commission regulates the betting product, and the punter on a financial spread bet is in a different market from the punter on a fixed-odds football coupon. The dual regulation is the reason a Spreadex account asks for a different kind of information than a Coral or Unibet account, and the reason the two products have different risk profiles. The £60 in fixed-odds free bets that come with a Spreadex new-customer offer is a Commission-regulated product; the financial spread bet the same account can place is FCA-regulated. The two sit on the same platform but in different regulatory homes.

The player protection frame is built around three pieces. GAMSTOP is the national multi-operator online self-exclusion scheme, mandatory for online operators since 31 March 2020, with periods of six months, one year, five years, or five years with auto-renewal; after the minimum period the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it. GAMSTOP covers online sites and apps; betting shops use a separate service. The financial vulnerability check is an LCCP condition in force since 30 August 2024, applied to licensed remote betting when a customer’s deposits minus withdrawals exceed £150 in a rolling 30 days (since 28 February 2025); the check is a public-record check (for example bankruptcy or county court judgments), not an income check and not a credit reference check. Financial risk assessments — the affordability checks of the press — are announced in a staged plan, with no start date.

The minimum age is 18, and name, address and date of birth are verified before a customer can deposit or gamble, including with a free bet or bonus. The verification has been in force since 7 May 2019 and means no anonymous play at a licensed site. The trade is clear: a licensed book is a verified account, a known punter, a tracked bet, and a regulated complaint route. An unlicensed book is none of those. The Gambling Commission’s public register is searchable by business name, trading name, domain or account number, and the register is the only place to confirm a licence before depositing.

The 19 January 2026 promotion rules are the centrepiece of this page. The 10x cap on wagering requirements is the rule that draws the line; the mixed-product ban is the rule that closes the cross-sell loophole. The rules are not retrospective, and offers opened before 19 January 2026 may still be settled under their original terms. New offers opened after the date are bound by the rules, and the table on this page reads the rules into each brand’s terms. Whether the 10x cap applies to free bets with no wagering condition has not been established, and the page treats it as an open question rather than a settled one.

What an offer cannot ask of a customer

A mixed-product promotion is an offer that requires a customer to gamble on two or more product types — betting, casino, bingo, lottery — in order to claim a benefit. A free bet that requires the punter to play a slot to unlock it is a mixed-product promotion. A casino bonus that requires a sports bet to release the cash is a mixed-product promotion. The clause outlaws the structure, not the individual offers; a sportsbook can still offer a sports sign-up bonus and a casino sign-up bonus, but it cannot tie the two together. The shape of the welcome package at most UK sportsbooks has changed since the rule came in, and the change is a quiet one — the casino leg is no longer the lever that releases the sports leg, and the sports leg is no longer the lever that releases the casino leg.

The wagering cap is the second clause. A 10x cap means a £10 bonus cannot require more than £100 of betting turnover, a £50 bonus cannot require more than £500 of turnover, and a £100 bonus cannot require more than £1,000. The cap applies per offer, not per account, and the Commission is the body that enforces it. The cap is published as a consultation outcome and a policy note, and the text is on the Commission’s website; the cap is not a market code of practice, it is a condition of the licence. The offer mechanics on this page are read against the cap, and any offer that implies a higher multiple is either pre-2026 or non-compliant.

The cap’s lower bound is not set. An operator can offer a 1x bonus (effectively a cash refund), a 3x bonus, a 5x bonus, or a 10x bonus, and each is lawful. The cap is the ceiling, and the floor is the operator’s commercial choice. The market’s shape after January 2026 is a wider range of multiples than the pre-2026 market, because every operator now has a cleaner reason to compete on the multiple (the headline is no longer a question of who can ask the most turnover). A reader comparing two offers should look first at the multiple, second at the minimum odds, third at the expiry. The headline number is the back of the comparison.

Responsible gambling: the frame an enhanced odds offer sits inside

An enhanced odds offer is a marketing product, and the marketing sits inside a wider frame of player protection. The frame is the Commission’s safer gambling regime, and the frame’s pieces are GAMSTOP, the financial vulnerability check, deposit limits, and a network of help services. The frame is not a marketing slogan; it is a condition of the licence. The frame is the reason a licensed book asks for a name, an address, a date of birth, and (above a deposit threshold) a public-record check before a bet can be placed.

GAMSTOP is the centrepiece. A punter who registers with GAMSTOP is excluded from every online gambling site and app run by a GB-licensed operator, for a period of their choice (six months, one year, five years, or five years with auto-renewal). After the minimum period the exclusion stays in place for a further seven years unless the punter asks GAMSTOP to remove it. The exclusion covers online only; betting shops are covered by a separate service. Every brand reviewed on this page is a GAMSTOP member. A punter who has self-excluded and then opens a new account is in breach of the self-exclusion, and the operator is in breach of the licence condition. The two-way ban is the strictest piece of consumer protection in the GB market.

The financial vulnerability check is the second piece. The check applies to licensed remote betting when a customer’s deposits minus withdrawals exceed £150 in a rolling 30 days. The check is a public-record check — bankruptcy, county court judgments, IVAs, similar registers — and is not an income check and not a credit reference check. The check is run by the operator, not by the Commission, and the operator decides what the result means for the customer’s account. A punter who fails the check may be asked for source-of-funds information, may have their deposit limit reduced, or may be asked to take a cooling-off period. The mechanics of the check are the operator’s commercial decision; the trigger is the Commission’s rule.

Deposit limits are the third piece. Operators must offer a gross deposit limit on a fixed time frame — daily, weekly, monthly — and the punter sets the limit at the time of account opening. The first phase of the regime has been in force since 31 October 2025; a second phase was postponed to 30 September 2026, and whether it is live is not established. Limits are the punter’s choice; the state does not set a default ceiling. A punter who wants to set a £10 daily deposit limit can do so; a punter who wants to set a £10,000 weekly limit can do so too. The frame is the offer of a limit, not a cap on the limit.

Help services are the fourth piece. GamCare runs the National Gambling Helpline, GambleAware funds treatment and education, the NHS runs gambling clinics in several regions, and Gamblers Anonymous runs peer-support meetings. Betfred’s app lists responsible gambling information and GambleAware support contacts; DAZN Bet provides deposit limits, loss limits and wagering limits as safer gambling tools. The pattern at every licensed operator is the same: a safer gambling page in the account, a link to GamCare or GambleAware, and the option to set or change limits from the account.

A sign-up offer is a marketing product, and marketing is a moment of risk for the punter. The frame is what catches the moment. A punter who reads the offer’s terms, sets a deposit limit, and is aware of the GAMSTOP option is the punter the frame is built for. A punter who skips the terms, lifts the deposit limit, and ignores the safer gambling page is a punter the frame cannot help, and a punter the Commission is gradually tightening the rules to reach.

Coral: a £40 free bet at 7-day expiry

Coral’s sports welcome offer is “Get £40 in free bets when you bet £20”. A deposit and a sports bet of £20 or more at minimum odds of 2.0 (1/1) is the qualifying condition; £40 in free bets is the headline; the free bets are issued within seven days of the qualifying bet settling and expire seven days after issue. The offer is for new GB customers who opt in, and the qualifying deposit must be a debit card or instant bank transfer. Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly are among the listed payment options.

The offer’s headline-to-cost ratio is reasonable. A £20 qualifying bet at 2.0 returns £40, of which £20 is profit and £20 is the stake; the £40 of free bets then arrives. The wagering requirement is not stated in Coral’s terms, so the 10x cap is the binding case — £400 of turnover at the cap, less at lower multiples. The seven-day expiry on the free bet is the offer’s tightest condition; a punter who does not use the free bet inside the window loses the offer. The decision rule is whether the punter can place a £20 qualifying bet at 2.0 or longer in the seven days before the offer window opens, and whether they can place a £40 free bet at a price the free bet’s expected value can bear in the seven days after it lands.

Coral’s wider product is broader than the welcome offer. The brand runs a free daily Reward Shaker, an Odds Booster on hundreds of markets, and free-to-play games such as Football Super Series with a £10,000 jackpot. The pattern is the high-street bookmaker’s pattern: a welcome offer to acquire, a daily mechanic to retain, and a free-to-play product to occupy the customer’s time between bets. Coral is a strong pick for a punter who wants the welcome offer on the front of the page and the daily product behind it, and the seven-day expiry is the trade for the headline number.

The verdict on Coral is that the offer is competitive at the headline and tight at the expiry, and the gap is the part to read. A punter who has time to use a £40 free bet inside a week is the punter the offer is built for; a punter who bets once on a Saturday and ignores the account for the rest of the month is paying for an offer they will not use. The Commission’s cap is the safety net; Coral’s terms are the contract.

bet365: the in-play product the welcome offer sits behind

bet365’s UK product is the deepest in the comparison. Bet Builder+ combines markets from one event into a single bet, available pre-match and in-play. Super Boosts are a daily menu of enhanced prices on selected events, paid as cash. Winnings Boosts apply to Bet Builders and selected singles. Daily Bet Boosts are a separate category of price promotion. The product set is the broadest in the table, and the welcome offer sits behind it.

The welcome offer’s headline is a £30 in free bets for new customers, credited as three £10 free bet tokens after a deposit of at least £5 and a first single or each-way bet of at least 5p at odds of 1/1 or greater. The structure is the same as Sky Bet’s offer, and the comparison is direct: both brands split the free bet into three tokens, both qualify at 1/1, both credit on the same 7-day shape. The difference is the product behind the offer. A punter who has a bet365 account for the in-play markets, the Bet Builder+, and the Super Boosts is a punter who will use the free bet inside the seven-day window; a punter who only opens the account for the welcome offer will not.

The verdict on bet365 is that the brand is the strongest in-play product in the comparison, and the welcome offer is a smaller reason to open an account than the product behind it. A punter whose betting is dominated by in-play markets and accumulators is the punter bet365 is built for; a punter who places one Saturday accumulator and one Tuesday night football single is overpaying for the product they do not use.

Unibet: a £40 free bet on a 7-day clock

Unibet’s sports welcome offer is “Get £40 in free bets when you bet £20”. The structure is the same as Coral’s headline, with a small difference in the wording of the expiry: Unibet’s free bets expire within seven days of issue, where Coral’s expire seven days after issue. The qualifying deposit must be a debit card or instant bank transfer, and the offer is for new GB customers.

Unibet has operated since 1999, and its UK site is run by Platinum Gaming Limited, Gibraltar, under Gambling Commission account 45322. The brand’s product is broader than Coral’s: Bet Builder, daily Uniboosts, live streaming through Unibet TV, in-play betting, Best Odds Guaranteed on horse racing, and Cash Out on thousands of markets. The Welcome offer is the front of a wider product, and the product is the reason a punter would stay beyond the seven-day window. Unibet TV is a notable piece — live streaming on selected events is a feature that turns an in-play book into a watching-and-betting book, and the feature is part of the reason the brand’s customer base is heavier on in-play than on pre-match accumulators.

The verdict on Unibet is that the offer is the same headline as Coral with a slightly tighter expiry wording and a broader product behind it. A punter who wants the £40 headline and the live streaming is the punter the offer is built for; a punter who only wants the £40 headline is paying for a product they will not use. The brand is one of the strongest in-play books in the comparison, and the welcome offer is the cheapest way in.

Sky Bet: a £30 free bet split into three £10 tokens

Sky Bet’s welcome offer for new customers is £30 in free bets, credited as three £10 free bet tokens after a deposit of at least £5 and a first single or each-way bet of at least 5p at odds of 1/1 or greater. The structure is the same as bet365’s offer, and the comparison is direct: both split the free bet, both qualify at 1/1, both expire on the same 7-day shape. The minimum deposit of £5 is the lowest in the table, and the 5p minimum stake is the lowest qualifying stake in the comparison.

The minimum deposit of £5 changes the calculus. A punter who wants to test a bookmaker’s product before committing a larger deposit has a £5 entry point at Sky Bet, where most competitors set the floor at £10. The 5p qualifying stake is a structural feature of Sky Bet’s product — a low-stake customer can clear the qualifying bet for a few pence and still earn the £30 of free bets. The trade is that the free bet’s value is the same as a higher-deposit offer’s, so the implied return on the qualifying deposit is higher at Sky Bet than at most competitors.

The verdict on Sky Bet is that the offer is the lowest-friction sign-up in the comparison, and the £30 headline is enough to make the offer worth taking. A punter who has never used Sky Bet’s product and wants to test it for £5 is the punter the offer is built for; a punter who already has a Sky Bet account and is shopping for a second book is a different customer, and Sky Bet’s offer is the comparison point rather than the destination.

BetMGM: four £10 free bets, split by market type

BetMGM’s sports welcome offer for new UK customers is four £10 free bets, credited after a deposit of £10 or more and a sports bet within seven days. The structure is the unusual one: two of the free bets are football accumulators of four or more selections, and two are sports multiples of two or more. Each free bet is valid for seven days, with minimum odds and opt-in required.

The split by market type is the offer’s most distinctive condition. A punter who wants the welcome bonus has to use two of the four tokens on football accumulators, and the other two on sports multiples — there is no flat £10 token that can be used on any market. The structure pushes the punter into accumulator markets, which carry a higher margin than singles, and the effective cost of the offer is higher than a flat-token offer’s. A punter who backs football accumulators regularly is the customer the offer is built for; a punter who places singles will not use two of the four tokens.

BetMGM is licensed under LeoVegas Gaming PLC, on Gambling Commission account 39198. The brand’s product is broader than the welcome offer: the LeoVegas platform’s sportsbook is a separate product from the casino, and the two are not tied together by a mixed-product promotion. A punter who wants a sportsbook with a casino fallback has both products in one account, and the welcome offers are independent. The trade is that neither offer is at the £40 headline of Coral or Unibet, and the offer is split in a way that suits a particular punter rather than the general case.

The verdict on BetMGM is that the offer is the most structured in the comparison, and the structure is the trade. The offer is built for a punter who backs football accumulators; one who does not will use two of the four tokens on markets they would not have otherwise backed. The brand is the strongest match for a particular kind of punter rather than for the average case, and the welcome offer is the same shape as the product behind it.

BoyleSports: a £20 free bet, a £5 minimum, and the multi-bet menu

BoyleSports’ sports welcome offer for UK players is £20 in free bets when a £10 bet is placed. Irish players get €30 in free bets for a €10 bet. The offer is one of the simpler in the table, and the structure is the closest to a textbook example. The £10 qualifying bet at the bookmaker’s minimum odds is the gate; the £20 free bet is the headline; the seven-day expiry is the window.

BoyleSports’ wider product is the multi-bet menu. Acca Insurance requires opt-in, a minimum stake of £5, minimum odds of 1/2, and pays a maximum refund of £20 as a free bet that expires in seven days; bets must be placed and settled on the same day. Acca Loyalty requires opt-in, a £5 minimum stake, minimum combined odds of 3/1, and five or more settled legs, with a free bet expiring after seven days. The two products are the same shape — opt-in, free bet refund, seven-day expiry — and the difference is the trigger (one losing leg for Insurance, five winning legs for Loyalty). A punter who builds accumulators is the customer both products are built for.

The verdict on BoyleSports is that the offer is the simplest in the comparison, and the multi-bet products are the strongest part of the wider product. The offer is aimed at a punter who builds accumulators and wants insurance on the one leg that loses; a punter who only places singles is overpaying for a feature they will not use.

Smarkets and SBK: a £60 free bet at 48 hours

Smarkets’ SBK sportsbook has the most generous headline in the table: a £20 first deposit and a £20 bet at minimum odds of 3.0 earns £60 in free bets within 48 hours. The qualifying price is 3.0 — twice the floor at Coral and Unibet — and the headline is the highest in the comparison.

The trade is the qualifying price. A £20 bet at 3.0 has a one-in-three chance of winning, and a punter who backs a 3.0 shot on a single bet is taking a meaningful risk on the qualifying bet. The £60 of free bets is paid within 48 hours of the qualifying bet settling, and the offer is the fastest in the table — most competitors’ free bets arrive within seven days. The product behind the offer is the SBK sportsbook: Cash Out, Bet Builder, and live horse racing streams. Smarkets’ exchange is a separate product on the same account, and the two sit side by side rather than as a single bookmaker.

The verdict on Smarkets and SBK is that the offer is the highest headline at the highest qualifying price, and the trade is the trade. A punter who can find a 3.0 shot they want to back is the customer the offer is built for; a punter who wants a low-risk qualifying bet should look elsewhere. The 48-hour settlement is the offer’s quiet strength, and the live horse racing streams are the offer’s quiet product.

Matchbook: 110 days of commission-free betting

Matchbook’s new-customer offer is 110 days of commission-free betting from registration for customers who register with a code and make a deposit. Standard commission applies afterwards. The offer is structurally different from the rest of the table: there is no free bet, no qualifying bet, no expiry on a token. The offer is a commission holiday on an exchange.

The shape of the offer is the shape of the exchange. Matchbook is a betting exchange — a platform where punters back and lay against each other, with the operator taking a commission on net winnings. A 110-day commission-free period is a meaningful saving on a betting exchange; the standard commission on a UK betting exchange is 2-5% of net winnings, and 110 days of zero commission is a real number. A punter who uses an exchange for matched betting, value betting, or trading is the customer the offer is built for; a punter who has never used an exchange is paying for a product they will not use.

The verdict on Matchbook is that the offer is the only commission-based welcome in the comparison, and the offer suits a different punter from the rest of the table. The product is a betting exchange, not a sportsbook, and the comparison with Coral or Unibet is a comparison of different products. A punter who wants both should consider a matched-betting setup with one bookmaker and one exchange; a punter who only wants a sportsbook should look elsewhere.

Betfred: the offer in the app

Betfred’s app lists new-customer free bets and free spins subject to terms. The app also lists responsible gambling information and GambleAware support contacts. The offer’s headline is not on the home page, and the comparison with the rest of the table is a comparison with a brand that has chosen not to lead with a welcome offer.

The decision to compete on odds and features rather than on a welcome bonus is a commercial choice. Betfred is a high-street bookmaker with a long history in the UK market, and the brand’s customer base is heavier on horse racing and football than on accumulators and in-play. A punter who wants a high-street bookmaker with a deep horse racing product is the customer Betfred is built for; a punter who wants the £40 welcome offer should look at Coral or Unibet.

The verdict on Betfred is that the brand is the most “no headline offer” in the comparison, and the choice is the brand’s commercial one. A punter who wants a welcome bonus should look elsewhere; a punter who wants the high-street product without one should look here.

DAZN Bet: the in-play book with the broader safer gambling frame

DAZN Bet offers Cash Out, Bet Builder, daily bet boosts and in-play betting. Cash out availability is not guaranteed, and bets stand if it is unavailable. The brand’s product is an in-play book with a bet builder and a daily boost menu, and the brand’s safer gambling frame is the broader one: deposit limits, loss limits and wagering limits are all available. The three limits cover the three dimensions a punter might want to control, and the brand is the strongest safer-gambling product in the table.

The decision rule on cash out is the same as at every bookmaker: the feature is not guaranteed, and a bet that is placed when cash out is unavailable is a bet that stands. A punter who plans their betting around cash out should not assume the feature will be there for every bet; a punter who treats cash out as a backup is the customer the feature is built for.

The verdict on DAZN Bet is that the brand is the strongest safer-gambling product in the comparison, and the in-play product is the wider reason to open an account. A punter who wants in-play betting with a broader safer-gambling frame is the customer the brand is built for; a punter who wants a £40 welcome offer should look elsewhere.

BetTom: a 50% back offer with a casino leg

BetTom’s sports welcome offer is 50% back as a free bet of up to £50, with a matching 50% back up to £50 as free slot funds for casino play. The structure is unusual: the offer is 50% back on the first bet, with the same percentage back on casino. Full terms apply.

The structure sits inside the mixed-product ban. The offer is a single promotion that requires gambling on two product types — sports betting and casino — and the offer’s survival in 2026 is the question the page cannot answer. If the offer is a sports sign-up promotion that requires a casino bet to release the free bet, it is a mixed-product promotion and is no longer lawful. If the offer is two independent promotions on the same account, the comparison is fair. The terms are the place to read this; the page’s role is to flag the question.

The verdict on BetTom is that the offer’s structure is the question to read, and the answer is in the operator’s own terms. A punter who wants a single-product offer should look at Coral, Unibet or Sky Bet; a punter who is comfortable with a mixed-product offer and reads the terms should make their own call.

NetBet: the daily boost product with a stats page

NetBet offers Daily Boosts, Profit Boosts and free bet offers, a Bet Builder with instant dynamic odds, and sports stats for major leagues. The product is broader than the welcome offer, and the comparison with the rest of the table is a comparison of a brand that competes on daily mechanics rather than on a sign-up headline. The sports stats page is the brand’s quiet strength — a punter who does their own research has the data on the same page as the price.

The verdict on NetBet is that the brand is the strongest daily-mechanic product in the comparison, and the welcome offer is not the headline. A punter who wants a daily product with a stats page is who NetBet is built for; a £40 welcome offer is better chased elsewhere.

Star Sports: the weekend enhanced boost

Star Sports offers pre-event and in-play markets with Bet Boosts, Daily Specials and Weekend Enhanced Boosts, plus in-play betting on football, horse racing, golf and US sports. The product is an in-play book with a weekend-focused boost menu, and the brand’s customer base is heavier on horse racing and golf than on football accumulators.

The verdict on Star Sports is that the brand is the most weekend-focused in the comparison, and the in-play product is the wider reason to open an account. The brand is built for a punter who bets on horse racing and golf on a Saturday; the £40 welcome offer is better chased elsewhere.

Spreadex: the dual-regulation bookmaker

Spreadex is regulated by the Financial Conduct Authority for spread betting and by the Gambling Commission for fixed-odds betting, and the company states that spread betting losses can exceed the deposit. The new-customer offer is £60 in free bets for a £10 fixed-odds bet, with the free bets usable across fixed odds and spread betting; the qualifying bet must be placed within 28 days of opening the account. The qualifying bet must be at minimum odds of 1/2. The fixed-odds offer also includes Acca Boosts that give a cash boost from 5% up to 100% on football accumulators of three or more selections, depending on the number of legs.

The dual regulation is the brand’s most distinctive feature. A Spreadex account is two products in one: a fixed-odds sportsbook regulated by the Commission, and a financial spread betting platform regulated by the FCA. The 28-day window on the qualifying bet is the longest in the table, and the £60 headline is the second highest after Smarkets’ SBK. The trade is the dual product: a punter who opens a Spreadex account for the £60 free bet is opening a financial spread betting account too, and the FCA-regulated product is a different proposition from the fixed-odds product.

The verdict on Spreadex is that the offer is the most generous in the table by headline, and the dual regulation is the trade. A punter who wants a fixed-odds bookmaker with the option to use financial spread betting is the customer the brand is built for; a punter who only wants a fixed-odds bookmaker is paying for a product they will not use.

Kwiff: the Supercharge feature and the surprise mechanic

Kwiff’s Supercharge feature can instantly boost the odds on a bet — for example from 2/1 to 20/1 — and it can apply to single or multi bets on any sport. The brand also offers Bet Builder and Bet Builder+ (combining Bet Builder bets from different games) and a guaranteed weekend acca boost. The Supercharge feature is the brand’s most distinctive mechanic, and the surprise is the point: the punter does not know in advance which bets will be Supercharged.

The surprise mechanic is a structural feature of the product. A punter who places a bet at Kwiff may find the bet Supercharged after placement, with the boosted price applied automatically. The feature is not the same as a daily boost menu at bet365 or Unibet; the boost is not advertised in advance, and the punter’s only signal is the bet’s odds changing after placement. The trade is the unpredictability: a punter who likes the surprise is the customer the feature is built for; a punter who plans their staking around a known boost is the customer who should look elsewhere.

The verdict on Kwiff is that the brand is the most distinctive product in the comparison, and the Supercharge feature is the reason to open an account. The brand is built for a punter who likes the surprise mechanic; a £40 welcome offer is better chased elsewhere.

BetVictor: the price boost bookmaker

BetVictor offers regular price boosts, acca offers and free bets on selected events, with welcome offers shown in the app and governed by the customer terms and conditions. The product is a price-boost bookmaker with a daily menu and a customer-terms framework, and the comparison with the rest of the table is a comparison of a brand that competes on price rather than on a welcome headline.

The verdict on BetVictor is that the brand is a price-boost bookmaker, and the welcome offer is in the app. A punter who wants a brand that competes on price is the customer BetVictor is built for; a punter who wants a £40 welcome offer should look elsewhere.

QuinnBet: the free bet with a market and bet-type range

QuinnBet’s free bets are valid for 7 days from credit and can be used on any market at odds of 1/2 (1.5) or greater, with maximum odds of 50/1; straight accumulators are allowed but Trixies, Patents and Yankees are not. The structure is the most detailed in the table, and the range from 1/2 to 50/1 covers almost every market the punter might want to use the free bet on. The excluded multi-bet types are the trade: a punter who wants to use the free bet on a Lucky 15 or a Heinz is not the customer QuinnBet is building the offer for.

The verdict on QuinnBet is that the offer is the most detailed in the comparison, and the detail is the offer’s strength. The offer fits a punter who places singles and straight accumulators; a punter who builds multi-bet combinations should look elsewhere.

The arithmetic, again: a single worked example to take away

The worked example is the core of the page. It uses Coral’s welcome offer and the 10x cap in force since 19 January 2026. The arithmetic is in plain prose, the inputs are stated, and the conclusion is a band.

A £20 qualifying bet at minimum odds of 2.0 (1/1) earns £40 in free bets, expiring seven days after issue. Under the Commission’s cap, the wagering requirement on a £40 bonus cannot exceed 10x. A £40 free bet at 10x turnover is £400 of betting. At a 5% market margin (typical of a major football market), £400 of turnover costs £20 in expected loss. At an 8% market margin (typical of a horse racing market), £400 of turnover costs £32. At a 4x turnover, the cost is roughly half. The expected cost of clearing the offer, before the free bet has paid a penny, sits in a band from roughly £5 to £32 depending on the multiple and the market.

The free bet’s expected value, on the same assumptions, is the stake multiplied by the odds minus one and divided by the odds. A £40 free bet at 2.0 has an expected return of £20; at 3.0, £26.67; at 4.0, £30. The expected value of the free bet, less the cost of clearing the offer, is the offer’s net expected value. A punter who can find a 3.0 shot and place the free bet at 4x turnover is roughly breaking even; a punter who places the free bet at 10x turnover on a horse racing market is paying to take the offer.

The arithmetic is an estimate, not a guarantee. A single punter on a single coupon can land anywhere inside the band or outside it. The expected cost is the cost averaged over many bets and many coupons, on markets and at margins the punter does not control. The right way to read the offer is that the headline is the headline, the cost is the cost, and the difference is the offer’s real value.

Open questions

Three questions sit open, and the page flags them rather than answering them. The first is whether the 10x cap applies to free bets with no wagering condition; the page treats it as an open question. The second is whether the second phase of the deposit limit regime is live; the postponed date is 30 September 2026 and whether it is in force is not stated, and the page treats it as an open question. The third is the timing of the financial risk assessment regime; the Commission published an article on 7 July 2026 but there is no start date, and the page treats it as announced and staged rather than in force. The pattern is the same: where a fact has not been confirmed, the page does not invent one.

The financial arithmetic on the worked example is an estimate, not a guarantee. The market margins and wagering multiples are stated as bands; the expected cost is stated as a band; the free bet’s expected value is stated as a function of the odds. A punter who places a single bet at a single set of odds on a single coupon can land anywhere in the band or outside it. The estimate is the right way to think about an offer’s real value over many bets and many coupons; the offer’s value on a single coupon is the punter’s own calculation.

The offer mechanics on each brand are stated from the operator’s own terms. The mechanics may change; the operator’s terms are the contract. A punter who opens an account on the strength of a welcome offer should read the offer’s terms at the point of opening, and the offer’s terms are the place to verify the wagering multiple, the minimum odds, and the expiry. The Commission’s public register is the place to verify a licence; the operator’s terms are the place to verify an offer.

Frequently asked questions

What does “enhanced win” mean in golf betting?

An enhanced win market is a price boost on the outright winner market of a golf tournament — the bookmaker raises the price on one or more players above the market price, and the punter backs the selection at the boosted price. The boost is paid in cash if the selection wins, and the stake is returned. The bookmaker’s cost is the difference between the boosted price and the market price, paid out only on a win; the punter’s trade is the chance the player does not win and the opportunity cost of placing the bet at one bookmaker rather than another. The boost is the same mechanic as a Super Boost on a football match, applied to a longer-odds market.

What is “enhanced win only” betting?

An enhanced win only market is a price boost that pays only on the win part of an each-way bet. The place part of the bet is paid at the un-boosted price. The mechanic is common in horse racing and golf, where each-way betting is a standard part of the market, and a boost that applies only to the win is a smaller boost than a boost that applies to both win and place. A punter who backs a 20/1 shot each way at an enhanced win price is taking the place part at the un-boosted price, and the boost applies only to the win. The each-way terms vary by race, by operator, and by number of runners, and the punter’s terms are the place to read the exact split.

What is an enhanced bet?

An enhanced bet is a bet placed at a price higher than the market price, typically as a one-off price boost on a specific event. The mechanic is the same as a Super Boost or a daily boost: the bookmaker raises the price on one outcome, the punter backs the selection at the boosted price, and the stake returns at the boosted price if the selection wins. The cost of the boost to the bookmaker is the difference between the boosted price and the market price, paid out only on a win. The cost of the boost to the punter is the chance the selection loses and the opportunity cost of placing the bet at one bookmaker rather than another. An enhanced bet is a real offer on a single bet, and the trade is the same as any other price boost.

What is the maximum wagering requirement on a betting bonus in Great Britain?

The maximum is 10x, in force since 19 January 2026. A £10 bonus cannot require more than £100 of betting turnover before it can be withdrawn as cash; a £50 bonus is capped at £500; a £100 bonus is capped at £1,000. The cap is a condition of the licence and applies to every sign-up offer at every UK-licensed sportsbook from 19 January 2026 onwards. There is no lower limit; an operator can offer a 1x bonus, a 5x bonus, or a 10x bonus, and each is lawful. The cap is the ceiling, not the floor. Whether the cap applies to free bets with no wagering condition has not been established.

What do minimum odds and the wagering requirement mean in a sign-up offer?

The minimum odds are the shortest price the qualifying bet may be at for the bet to count. A 1/2 minimum is the lowest in the comparison, and almost every selection on a major market beats it. A 1/1 minimum is the standard at Coral and Unibet. A 3.0 minimum is the highest, at Smarkets’ SBK. The wagering requirement is the multiple of the bonus that must be turned over before the bonus can be withdrawn as cash. A 1x bonus is effectively a cash refund; a 10x bonus is the maximum under the Commission’s cap. The two numbers are the conditions on the offer; the headline free bet is the headline.

Why is the stake of a free bet not paid back with the winnings?

A free bet is a token that lets the punter place a bet without risking their own money. The bookmaker’s cost is the punter’s expected profit, which is calculated on the stake as if it were a real bet. If the bookmaker paid back the stake as well, the offer would be worth twice as much, and the bookmaker’s expected cost would be twice as high. The mechanic is the same at every UK-licensed bookmaker, and the rule is the same at every one: a £40 free bet at 3.0 returns £80 of profit, not £120 of return. The £40 of stake is the bookmaker’s, and the punter keeps the profit. The rule is the rule.
