“Free” is a marketing word on a betting shop front. The punt that follows it carries a price the headline never names: a wagering multiple, a minimum odds threshold, an expiry in days, and a stake that walks away even when the bet wins. The free bet clubs that have become a fixture of the GB market are no different. What changes between brands is the size of that price and who ends up paying it — and that is the angle of this page, with the arithmetic to match.

A £25 free bet at 1.90 does not give you £25 if it wins. It returns the £22.50 of profit only, and that profit is itself a slice of what the market would have paid a real-money backer. Worked out across the legs of a typical two-way football match at 1.90/1.90 — a margin the industry sits on more or less every weekend — the average value lands between £11 and £12 of expected profit, never £22.50. That gap is the whole story of a free bet: what the bookmaker gives in the headline, what the bettor actually banks, and what the rules in between take off the top.

The bookmakers reviewed below are all GB-licensed remote operators on the Commission’s public register. The Commission’s promotion rules in force since 19 January 2026 put a 10x ceiling on wagering requirements and ban mixed-product offers that pull a sports customer into a casino game. They do not cap the headline figure of a bonus or set the odds threshold an offer has to honour, and they leave each operator free to set its own minimum odds, expiry and stake-returned rule. The result is a market that looks uniform from a distance and punishes in the small print. This page is the small print read aloud.

What a free bet club actually pays

A free bet club is the operator’s name for a recurring free-bet giveaway: place a qualifying wager during the week, claim a token of fixed money value, repeat. The headlines look identical across the GB market — “Bet £X, Get £Y in Free Bets” — but the working numbers diverge in three places that matter to anyone reading this who is not the marketing department.

The first is whether the stake is returned. Sky Bet’s free bets explicitly do not return the stake with winnings, and that is the rule most of the GB market follows. A £10 free bet at 3.0 wins you £20 of profit, not £30 of total return; the £10 stays with the bookmaker as the cost of the giveaway. Betboro’s matched free bet, Betway’s 1x-wagering free bets and Coral’s £40 free-bet bundle all carry the same stake-not-returned rule in their terms.

The second is the minimum odds attached to the qualifying bet. Coral requires 2.0 (1/1) on the £20 qualifying stake, Betboro requires 1.60 (3/5) on each leg of a three-selection first bet, and Betway’s free-bet wagering runs at odds of 1.75 or higher. A threshold of 2.0 is roughly the same as picking a market where the underdog has a real chance of winning; 1.60 lets you back a heavy favourite. The lower the threshold, the easier to qualify — but the smaller the edge, because the closer to 1.0 the price, the less the bookmaker is paying for the risk it has taken on.

The third is the expiry. Sky Bet’s free bets last 30 days; Coral’s free-bet bundle lasts 7; Betway’s 1x-wagering requirement has its own clock. A token that expires in 7 days has to be used midweek, not saved for Saturday’s big race. Pair a short expiry with a minimum-odds rule and the reader has, in practice, a much narrower choice than the headline figure suggested.

These three numbers — stake-not-returned, minimum odds, expiry — are the spine of every offer below. The headline figure is the marketing; the spine is the contract.

The 10x bonus cap, and what it actually changed

From 19 January 2026 the Commission’s promotion rules cap wagering requirements on bonuses at 10x, and forbid an offer that requires gambling on two or more product types. The cap is real and it is enforced: a £10 bonus at 50x wagering, which used to be common enough in the casino market, is no longer permitted, because £500 of qualifying bets would be needed to clear £10. Under the cap the same £10 bonus now needs no more than £100 of qualifying play. Mixed-product offers — “bet on football to get free spins”, the kind of bundle that used to land in a sportsbook inbox every other week — are out.

What the cap does not do is harder. It does not cap the headline bonus figure, so a £100 bonus at 10x still needs £1,000 of qualifying bets to release. It does not set a minimum odds threshold, so the qualifying bet can still be set at 1.5 or 1.75, leaving the operator free to nudge the bettor into a thin market. It does not change the stake-not-returned rule on a free bet — the cap covers bonuses with a wagering multiple, and whether it covers free bets with no wagering condition is, on the public record at the time of writing, not established. A bonus that earns itself out at 1x wagering, the kind of structure Betway now runs on its free bets, sits well below the 10x ceiling and is unaffected by it.

A wagering multiple is the number of times the bonus (or the bonus plus the deposit) has to be turned over before any winnings become withdrawable. The Commission’s cap limits how high that multiple can go; it does not bring it down to zero. Reading an offer that advertises “1x wagering” as “free” is a different kind of mistake, and one the marketing teams are happy to leave uncorrected.

Worked value: what a £25 free bet is worth at 1.90

The arithmetic of a free bet is short and worth showing once. The free-bet terms from research put the stake-not-returned structure in the open; the illustrative two-way market at decimal odds 1.90/1.90 (fractional 9/10) is the example, not a quoted price.

A £25 free bet placed on a 1.90 selection, winning, pays 25 × (1.90 − 1) = £22.50 of profit. The market itself, on a clean two-way line with no margin, would pay 1.90 back for every £1 staked — so £1 of stake returns £1.90. On the 1.90/1.90 line, the payout share is 1 ÷ (1/1.90 + 1/1.90) = 0.95, and the margin is 1 − 0.95 = 0.05, or 5% of every unit staked. The £22.50 of profit on a winning bet has to be scaled by that 5% the market keeps, so the average value of the £25 free bet across many bets, winning and losing, comes to £22.50 × 0.95 = £21.375, or roughly £21.38 of expected profit. After the 5% market margin, the £25 token is worth £25 × (0.90 ÷ 1.90) × 0.95, which lands between £11 and £12 of expected profit per token under the typical conditions most offers carry.

That is the average across many bets. No single bet pays that figure, and the operator is not promising it. What the average says is that a free bet whose headline is £25 is, in honest money, somewhere in the £11–£12 range — less than half the headline, before any minimum-odds or expiry rule cuts the field of bets further. A punt that costs £25 to clear in qualifying wagers, with a 1x playthrough on a thin market at 1.60, can come out behind even before the token is used.

The same arithmetic on a £10 token at the same 1.90/1.90 line lands between £4.50 and £5.00 of expected value; on a £40 token, between £18 and £20. The headline-to-value ratio is roughly stable at 45–50% across token sizes — that is the working gap between marketing and arithmetic in the GB free-bet market today.

The fundamentals: what every free bet club shares

Every free-bet club on the Commission’s register carries the same legal frame and the same small-print skeleton, which is what makes them comparable at all. Three things hold across the ten reviewed operators.

The first is verification before the first bet. The Commission’s identity checks, in force since 7 May 2019, require name, address and date of birth to be confirmed before any deposit or wager, including a free bet. Midnite shows the acca builder, popular accas and price boosts with maximum-stake limits on its UK site under Commission licence 101839; Kalooki Sportsbook names Kalooki Sports Book Ltd (company number 12938274) as the operator under account 57730, with GAMSTOP membership signed up. There is no anonymous play at a GB-licensed site, and there is no free bet without a verified name behind it.

The second is the 10x bonus cap and the mixed-product ban, both in force since 19 January 2026. Every welcome offer reviewed below complies, by construction: the structures shown are deposit-gated sports free bets at single-digit wagering multiples, not casino bundles with 50x playthroughs. None of the ten is asking a sports customer to wager on a casino game as a condition of the free bet.

The third is the GAMSTOP opt-out for any customer who wants to stop. Self-exclusion is a licence condition for every remote operator, with periods of six months, one year, five years, or five years with auto-renewal. The exclusion stays on the GAMSTOP register for seven years past the minimum period unless the customer asks for it to come off. That is the backstop, not the first line of defence, and the offer terms reviewed here do not touch it.

The landscape: what changes between the ten bookmakers

Where the ten reviewed operators diverge is in the four working numbers that decide whether the offer is worth the qualifying bet.

Coral pairs a £20 qualifying bet at minimum odds of 2.0 (1/1) with a £40 free-bet bundle issued within 7 days and expiring 7 days after issue. William Hill, on the acca side rather than the welcome side, scales a Football Acca Boost from 3% on a double to 200% on 20 or more legs, each leg at 1/5 or bigger, capped at £10,000 per online bet and running until 30 May 2027. Unibet mirrors Coral’s headline — “Get £40 in Free Bets when you bet £20” at minimum odds of 2.0, with the free bets expiring within 7 days — and stacks it with Best Odds Guaranteed on horse racing, Uniboosts, Unibet TV, in-play markets and Cash Out on thousands of selections. Betway keeps it lower-stakes: a £10 minimum deposit and 1x wagering on the free bets at 1.75 or higher.

Spreadex threads fixed odds and spread betting through one offer: £60 in free bets from a £10 fixed-odds qualifying bet, usable across both. The qualifying bet has to land within 28 days of account opening, and spread-betting losses can exceed deposits — a feature, not a warning. Sporting Index does the same with three £10 fixed-odds free bets, three £5 Total Goals spread bets, three £5 Winning Favourites spread bets and a £1 Race Index spread bet, the qualifying fixed-odds bet at minimum odds of 1/2 and not cashed out early.

BoyleSports pairs a £10 bet with £20 in free bets, and layers an Acca Insurance at a £5 minimum stake, 1/2 minimum odds, settled same-day and refunded as a free bet capped at £20 and expiring in 7 days, plus an Acca Loyalty for a £5 stake at combined odds of 3/1 across 5 or more settled legs, free bet expiring after 7 days. Betboro runs a 100% matched free bet of up to £25 on the first qualifying wager, requiring a debit-card deposit of at least £10 and a first bet of £5 to £25 across three selections at 1.60 or higher. QuinnBet fits £20 in free bets at 7-day expiry, usable at 1/2 (1.5) or greater up to 50/1, with straight accumulators allowed and Trixies, Patents and Yankees excluded. Dabble’s “Bet £10, Get £10 in Free Bets” runs with a 7-day free-bet expiry, stake not returned and minimum odds applying.

Bet Ahoy pairs a £10 qualifying bet with a £10 free-bet bundle made up of a £5 sports bet and a £5 acca. BetTom runs a 50% back-as-free-bet up to £50 on the sports side, with a matching 50% back up to £50 as free slot funds on the casino side — the kind of dual-product bundle that the Commission’s mixed-product ban takes off the table after 19 January 2026 in its previous form, and which BetTom’s terms now structure as two separate opt-ins rather than one cross-product condition. Sky Bet keeps the free bets on single or each-way markets only, excludes virtuals, expires the tokens in 30 days, and the stake is not returned.

Star Sports leans on Bet Boosts, Daily Specials and Weekend Enhanced Boosts with in-play markets on football, horse racing, golf and US sports. DAZN Bet offers Cash Out (with availability not guaranteed), Bet Builder, daily bet boosts and in-play betting, plus deposit limits, loss limits and wagering limits as safer-gambling tools. Kwiff layers a Supercharge feature that boosts odds on the spot — the in-app example goes from 2/1 to 20/1 — across single and multi bets on any sport, with Bet Builder, Bet Builder+ and a weekend acca boost.

Smarkets runs SBK alongside the exchange: a £20 first deposit and £20 bet at minimum odds of 3.0 unlocks £60 in free bets within 48 hours, with Cash Out, Bet Builder and live horse racing streams. BetVictor runs price boosts, acca offers and free bets on selected events, governed by the customer terms. Fitzwilliam Sports, the Dublin bookmaker with capped membership, runs a “High Stakes Welcome” subject to compliance criteria — the welcome is there; the headline number is not for public consumption. Bar One Racing, rebranded as BAR 1 Betting, is an Irish independent with shops across Ireland and horse racing sponsorships at Dundalk, Fairyhouse, Navan, The Curragh, Curraheen Park and Cork.

The mid-table is Betway at 1x wagering, 1.75 minimum odds, £10 minimum deposit; the high-stakes end is Spreadex’s £60 free-bet bundle and Unibet/Coral at 2.0 minimum odds. The right operator depends on what kind of betting the reader is doing, not on which headline is biggest.

The statute behind the offer

The framework behind every GB free-bet club is the Gambling Act 2005, with the Gambling (Licensing and Advertising) Act 2014 closing the point-of-consumption gap: any 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. Northern Ireland sits outside the 2005 Act under older law, and a GB licence regulates only Great Britain.

Licence types on the remote register cover remote general betting standard (real events), remote general betting standard (virtual events), remote general betting limited, remote pool betting and remote betting intermediary (the exchange licence). Every operator reviewed below holds a remote general betting standard (real events) licence; Coral adds a remote betting intermediary category alongside its general betting licence. The Commission’s public register is searchable by business name, trading name, domain or account number, and is the whole test of licence status. Domains prove nothing: a licensed operator may use .com or .co.uk, and an unlicensed operator can register either.

General Betting Duty is the operator’s tax on gross profits, currently 15%; from 1 April 2027 a new remote betting rate of 25% applies within it, with remote bets on UK horse racing, SSBTs, pool betting and in-person betting staying at 15%. Spread betting has its own rates: 3% on financial, 10% on other. The punter pays no tax on betting winnings in Great Britain. Whether operators pass duty on through odds is not established.

Advertising runs through the CAP Code (non-broadcast) and BCAP Code (broadcast), enforced by the ASA, alongside the Commission’s marketing conditions in the LCCP. CAP Code section 16 makes marketing socially responsible, forbids strong appeal to under-18s, and forbids anyone who is or seems to be under 25 from featuring in gambling advertising, with the exception of marketing placed where a bet can be made directly. That rule is about who appears in the advert, not who may bet. Whistle-to-whistle is an industry code, not law: since 1 August 2019 betting ads do not run on TV in the five minutes before and after a live sporting event before the 9pm watershed, with horse and greyhound racing excluded.

Responsible gambling: the limits that exist, and the ones that don’t

GAMSTOP is the multi-operator online self-exclusion scheme and a mandatory licence condition for every remote operator in Great Britain since 31 March 2020. Periods are six months, one year, five years, or five years with auto-renewal; after the minimum period the exclusion stays on the register for seven years unless the customer asks for it to come off. GAMSTOP covers online sites and apps; betting shops use a separate service.

A financial vulnerability check has applied to licensed remote betting since 30 August 2024, and the spend trigger of £150 net deposits in a rolling 30 days took effect on 28 February 2025. The check is a public-record one — bankruptcies, county court judgments — not an income check, not a credit-reference check. Financial risk assessments — the so-called affordability checks — were announced on 7 July 2026 in a staged plan with no start date. Write “announced, staged, no start date”, because nothing more is in force.

Deposit limits are a licence condition (RTS 12): operators must offer a gross deposit limit on a fixed time frame. The first changes applied on 31 October 2025; a second phase was postponed to 30 September 2026, and whether it is live is not established. There is no state-set deposit or loss ceiling. The customer sets the limit; the operator enforces it.

Credit cards are banned for gambling in Great Britain since 14 April 2020, including credit-card-funded e-wallet payments. Debit cards and bank-based payments are not covered. Source-of-funds questions at higher spend are normal under money-laundering rules. The Commission’s identity checks before the first deposit mean no anonymous play. Help: GamCare (National Gambling Helpline), GambleAware, NHS gambling clinics, Gamblers Anonymous. A licensed operator offers every one of these routes; an offshore operator offers none.

The ten bookmakers, side by side

The comparison that follows is ten GB-licensed remote operators on the Commission’s public register as of 30 October 2026. The “key subject” column is what each operator’s own terms state about the free-bet club’s working numbers — minimum odds, expiry, qualifying stake — and is not a quotation of the headline figure. The licence number is the Commission’s account number from the public register.

The licence column reads the same way across the table because the licence categories do. The right-hand column is where the reader makes the choice, and it does so on three questions the table cannot answer for them: how big a stake they want to commit to qualifying, how long they want the free-bet token to last, and whether they want to use it on singles, multiples or both.

Betboro

A 100% matched free bet of up to £25, with a £10 debit-card deposit and a first bet of £5 to £25 across three selections at 1.60 (3/5) or higher. The three-selection rule is the cost: a single bet will not qualify, the qualifying bet has to be an accumulator with three legs, and each leg has to clear 1.60. The stake of the free bet is not returned with the winnings.

For a bettor who already places accas at thin odds, the structure is not a stretch — the qualifying bet is the kind of bet they would have placed anyway, with a small extra profit if the bet lands. For a bettor whose bets are mostly singles, the qualifying requirement reshapes their habits for the duration of the offer. Either reader gets a free bet whose headline is the same as a single-selection £25 free bet; the path to claiming it is different, and on a thin acca at 1.60×1.60×1.60 — combined odds of 4.096 — the value of the qualifying stake is closer to its face value than the headline suggests.

The matched structure, capped at £25, is small relative to Coral’s £40 bundle or Spreadex’s £60 — but the qualifying multiple is a single wager rather than the bundled 1x of Betway or the 7-day clock of Coral. A modest offer that is honest about its cost.

Betmaster

Betmaster is operated by BM Solutions GB Ltd and holds Commission account 65699. The welcome structure sits inside the small-stake, low-1x-wagering end of the GB market, with the qualifying deposit and bet calibrated to customers who want the free-bet token as a small bonus on a routine deposit rather than a headline figure.

The brand sits in the same register corner as Betway: a free-bet club that does not pretend to be anything other than a 1x-wagering token at a price-sensitive minimum-odds threshold. A reader who wants a token whose qualifying bet is at odds of 1.75 or higher — the kind of bet they would have placed anyway — will find the offer unremarkable in the way most welcome offers become unremarkable once the £40-and-2.0 headlines are stripped back. The offer is for the reader who has stopped reading it as a deal.

Sporting Index

A £10 fixed-odds bet at minimum odds of 1/2 unlocks three £10 fixed-odds free bets, three £5 Total Goals spread bets, three £5 Winning Favourites spread bets and a £1 Race Index spread bet. The qualifying bet cannot be placed in-play and cannot be cashed out early. The fixed-odds free bets work on the standard stake-not-returned rule; the spread bets live on a different margin structure and can exceed the deposit.

For a punter who already uses both fixed odds and spread, the bundle is genuine value: ten distinct tokens, each calibrated to a different market, with the spread-bet tokens priced at a structure the fixed-odds reader may not have used before. For a reader who only bets fixed odds, the spread tokens are an unfamiliar extra rather than a prize, and the relevant tokens are the three £10 fixed-odds free bets. The fixed-odds leg of the offer is the same modest £30 of headline value as a Coral or Unibet bundle; the spread legs are a side door into a different product.

The qualifying bet is a routine fixed-odds wager at 1/2, well below Coral’s 2.0 and below Betway’s 1.75 — the easiest of the qualifying thresholds reviewed here to clear, which is why the headline figure sits at a lower multiplier of qualifying stake.

Fitzwilliam Sports

Fitzwilliam Sports is a Dublin bookmaker with capped membership, and its welcome is a “High Stakes Welcome” subject to compliance criteria. The headline figure is not public; the terms are available on request. The relevant licence is held by SBKI Limited on Commission account 48760.

This is the entry in the table for the reader who is not looking at a headline at all. A capped-membership bookmaker is, by definition, looking for a smaller and more selected customer base than Coral or Betway — the kind of bookmaker that prizes the existing punter over the new acquisition, and structures its welcome accordingly. The fact that no public headline is shown is not a marketing gap; it is a contract.

For a reader whose betting is regular enough to be invited into a capped membership, the offer is the kind that rewards that regularity in a way no headline can. For the rest of the market, the brand is a non-participant in the headline race and a clean example of why “free bet club” is not a uniform product.

Coral

“Get £40 in Free Bets when you bet £20”: a deposit and sports bet of £20 or more at minimum odds of 2.0 (1/1), with £40 in free bets issued within 7 days and expiring 7 days after issue. The qualifying bet has to be a debit-card or instant-bank-transfer wager; the welcome is for new GB customers who opt in. The stake is not returned. Coral stacks it with 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 headline figure is large; the qualifying threshold is also large. A £20 bet at 2.0 is a bet on something that the bookmaker thinks has roughly a 50/50 chance — closer to picking a coin-flip than a heavy favourite, and the qualifying stake is not on a market where 2.0 is the easy line. Coral is offering £40 of headline value in exchange for a £20 qualifying wager whose effective cost, in expectation, is closer to £10 of profit at a fair two-way line. The 7-day expiry on the free-bet bundle is tight: a token issued on Monday has to be used by the following Monday.

For a punter who would have bet on Saturday’s big race anyway, and who has a debit card in hand, the offer is the strongest headline in this list and a routine qualifying bet. For the casual customer who only bets during a major tournament, the 7-day clock and the 2.0 minimum odds together make the offer harder to clear than the headline suggests.

Bet Ahoy

A £10 qualifying bet for a £10 free-bet bundle made up of a £5 sports bet and a £5 acca. The two-token structure means the headline figure is split across two products: a flat single-bet free bet and an accumulator free bet, each with its own minimum-odds rule and its own expiry.

The split is the cost. A punter who normally bets singles will use the £5 sports token and leave the £5 acca token unredeemed; a punter who normally bets accas will do the opposite. The headline £10 in free bets only realises its full value for a bettor who uses both — and the structure rewards exactly that bettor with the smaller qualifying stake (£10 vs Coral’s £20). For a customer who only bets one way, the offer is a £5 headline dressed as £10.

Geoff Banks

The Geoff Banks app is published by GB Sports Advisors Ltd under Commission account 54095, with live in-play prices and ante-post markets on future events. No public welcome headline is reviewed here.

The brand sits on the register as a GB-licensed remote operator; the welcome offer, in the form the headline reviews work from, is not part of the public product. For a reader looking at this list for a free-bet club, the Geoff Banks entry is the row that says “licensed, not the same product”. A punt with a respected independent bookmaker is a different value proposition from a Coral £40 bundle, and the comparison does not bring them to a common denominator.

William Hill

The Football Acca Boost covers accas of two or more legs with each selection at 1/5 or bigger, scaling from 3% on a double up to 200% on 20 or more legs, with a maximum boost of £10,000 per online bet, running until 30 May 2027. The structure is an acca-fidelity reward rather than a free-bet club, and the working numbers belong to a different feature.

For a bettor whose bets are accumulator-heavy, the boost is the equivalent of a £10,000-per-bet top-up on a winning Saturday acca — the kind of feature that pays for itself once a month. For a bettor whose bets are singles, the boost does not engage. The minimum-odds threshold of 1/5 is well below the industry average and is the easiest qualifying line on this list. The 30 May 2027 expiry is the longest qualifying window reviewed here, and the acca structure is what the Commission still allows under the post-19 January promotion rules.

BetTom

A 50% back-as-free-bet of up to £50 on the sports side, with a matching 50% back up to £50 as free slot funds on the casino side. The terms structure the offer as two separate opt-ins: the sports free bet clears on sportsbook wagers, the casino free slot funds clears on casino play, and neither requires the other as a condition. Full terms apply.

The structure is the working answer to the post-19 January mixed-product ban: an operator that wanted to keep the headline of a sports-plus-casino bundle has split the bundle into two single-product offers that the Commission’s rules allow. The sports free bet is a routine stake-not-returned token; the casino free slot funds is its own bonus with its own wagering rule. The qualifying stake on the sports side and the qualifying stake on the casino side are separate; the headline £50 frees both sides only when the bettor plays both.

For a reader who plays both sports and casino, the offer is a genuine £100 of headline value across two products. For a reader who only plays one, the offer is a £50 headline dressed as £100.

Bar One Racing

Bar One Racing has rebranded as BAR 1 Betting, an Irish independent bookmaker with shops across Ireland and horse racing sponsorships at Dundalk, Fairyhouse, Navan, The Curragh, Curraheen Park and Cork. Commission account 56516 is held by Bar-One Racing Limited. No GB online welcome headline is reviewed here.

The brand is on the GB register, and the GB register is the right place to verify that; the product for GB online customers is not a free-bet club in the form the rest of this list is reviewing. For a reader who knows the Irish high-street bookmaker and wants to bet on Irish racing, the brand is the row that says “yes, GB-licensed, different product”. For the rest of the market, it sits in the same register corner as Fitzwilliam and Geoff Banks — present, licensed, but not a headline participant.

Which operator, which reader

The arithmetic on a £25 free bet at 1.90 — between £11 and £12 of expected profit, never £25 — is the same arithmetic on every offer above, scaled to the headline figure and the minimum-odds threshold. A Coral £40 bundle on a 2.0 qualifying line clears between £19 and £20 of expected value, and is the largest headline in the table reviewed. A Spreadex £60 bundle, fixed odds plus spread, clears between £28 and £30 of expected value on the fixed-odds leg alone, with the spread leg a separate product.

A bettor who wants the largest headline and can clear a £20 qualifying bet at 2.0 within a week is reading Coral or Unibet. A bettor who wants the smallest qualifying stake and does not mind a 1.60 three-leg acca is reading Betboro. A bettor who already bets on spreads is reading Sporting Index or Spreadex. A bettor whose bets are singles, who does not want to change their habits for the offer, is reading Betway at 1x wagering and 1.75 minimum odds — a smaller headline and a routine qualifying bet. A bettor whose bets are accas is reading William Hill’s boost and is not really reading the rest of this list.

For a bettor with a small budget, the Betway 1x structure is the cleanest cost: £10 deposit, £10 free bet, the qualifying bet at the kind of price the bettor would have picked anyway, and a 1x playthrough that releases the token without any further home-room. For a bettor with a routine Saturday habit, the Coral or Unibet £40 bundle is the largest headline that aligns with a routine qualifying bet. For a bettor with a high-stakes profile and a Compliance-criteria welcome, Fitzwilliam is the answer the table does not name.

The marketing word “free” is on the front of every offer reviewed here, and the rule that the stake is not returned is on the back of every one. The 10x bonus cap and the mixed-product ban are the framework; the minimum-odds threshold and the 7-day expiry are the practical cost. The reader who takes the offer seriously is the reader who reads it that way.

Frequently asked questions about free bet clubs

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

The Commission’s promotion rules, in force since 19 January 2026, cap wagering requirements on bonuses at 10x, so a £10 bonus at the cap needs £100 of qualifying bets to release. The cap does not change the stake-not-returned rule on a free bet, and it does not cap the headline figure of a bonus.

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

Minimum odds set the price the qualifying bet has to clear — Coral’s 2.0 is roughly a 50/50 line, Betway’s 1.75 is closer to a strong favourite. The wagering requirement is how many times the bonus has to be turned over before winnings are withdrawable. Both numbers are in the small print.

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