A promo code is the small string a bookmaker sometimes prints at the foot of an advert or the bottom of an email. It unlocks an offer — a sign-up package, a free bet, an odds boost. It is not the offer, and the offer is rarely the value it sounds like. In Great Britain the rules around what a bookmaker can ask a customer to do to clear a bonus changed on 19 January 2026: any wagering requirement on a bonus is capped at 10x, and mixed-product promotions (an offer that asks a customer to bet on football to claim free spins, for instance) are banned. The numbers that determine what an offer actually pays still come from each operator’s own terms — the minimum odds, the deadline, whether the stake comes back, what the free bet can be spent on.

This page is built around that gap between the marketing line and the arithmetic of clearing it. The retailers in the comparison below are the ten Gambling Commission-licensed brands in this review set; every figure quoted for them sits inside what their own terms say. No brand is “the only” licensed operator, and a place in any list is a comparison result, not a Commission endorsement.

Current as of 30 October 2026 against the Gambling Commission’s public register.

What a bookmaker promo code does in 2026

A promo code is a string of letters or numbers that the customer types into a registration form, a deposit screen or a bet slip to unlock a specific promotion. Some operators no longer use them at all: the offer applies automatically once the qualifying conditions are met, and the code is a relic of email and affiliate marketing. Where codes still exist, they are a routing mechanism, not a value — the offer behind the code is the same whether the customer types it in or not.

The offers themselves fall into a small number of shapes:

• Bet-and-get. Place a qualifying bet at or above a stated minimum stake, usually at a stated minimum price, and receive a set of free bets once the qualifying bet settles. The free bet is credited in tokens that expire, often within seven days.
• Stake-back. Place a first bet; if it loses, the stake is returned as a free bet, up to a stated cap. The refund is a free bet, not cash, and carries the same expiry and minimum-price rules.
• Acca insurance. A separate promotion on accumulators: if one leg lets the customer down, the stake is refunded as a free bet, up to a cap, when other conditions are met.
• Price boost. The bookmaker raises the price on a named selection or market for a window. A boost can be a one-off for a televised event or a daily feature.
• Profit boost on accumulators. A percentage uplift on the winnings of a winning acca, scaling with the number of legs.

Every one of these offers has a small print. The free bet is the most misunderstood, because the stake is not paid back with a winning free bet — a £10 free bet at 3/1 returns £30 of profit, not £40. The wagering requirement, where one exists, is the multiplier on the bonus that the customer must bet through before any winnings become withdrawable cash. Under the Commission’s promotion rules, that multiplier cannot exceed 10x on a bonus.

A sign-up package looks generous because the headline number is large. The honest figure is the one that comes out of the qualifying bet, the wagering requirement, the minimum price and the expiry taken together. Two offers with the same headline can be worth very different amounts of real money to a real bettor.

The landscape: ten GB-licensed brands, by the rules of their own terms

The retailers in this comparison hold a Gambling Commission remote general betting licence for real events. A licence is the floor: the minimum that lets an operator take a bet from someone in Great Britain, with the protections that come with it (identity verification, GAMSTOP coverage, access to alternative dispute resolution, the 10x bonus cap). It is not a ranking. The brands differ on the offer shape, the qualifying terms, the free-bet expiry, the product depth (in-play, bet builder, live streaming, cash out) and the everyday promotions that matter once the sign-up package is spent.

The table below sets out each brand’s licence and a one-line summary of what the operator’s own terms say about the offer this page is built around. Minimum odds, expiry, whether the stake is returned, and what counts as a qualifying bet are stated in the operator review that follows.

Every figure in the third column is a fact each operator publishes about its own offer. Where the source sets a minimum stake, a minimum price, an expiry or a payment-method restriction, those numbers are quoted in the operator review, not the table — the table is the licence and the headline, the review is the cost.

Sign-up offers in 2026: where the cost hides

A sign-up offer has four moving parts, and the cost of clearing it is the product of all four.

The first is the qualifying bet. Most bet-and-get offers require a first bet at a stated minimum stake and a stated minimum price — minimum odds of 1/1 (2.0 decimal) is the common floor. The qualifying bet is paid for in real money, settled from the customer’s cash balance, and either wins or loses on its own merits. A winning qualifying bet returns its stake and its profit; a losing one costs the customer the stake and unlocks the free bets. The qualifying bet is not a free bet: the stake is the customer’s.

The second is the free bet itself. A free bet is a token credited to the customer’s account after the qualifying bet settles. It can usually be spent on any market, sometimes at a minimum price (QuinnBet sets a 1/2 (1.5) floor on its free bets, with a maximum odds of 50/1; straight accumulators are allowed but Trixies, Patents and Yankees are not). The free bet expires — seven days is the norm, but each operator’s terms state its own window. The stake of a winning free bet is not returned: a £10 free bet at 3/1 returns £30 of profit, not £40.

The third is the wagering requirement, where one exists. A wagering requirement is a multiplier on the bonus that the customer must bet through before winnings become withdrawable cash. It is not the same as the qualifying bet; the qualifying bet is a separate stake that pays out on its own. The Commission’s promotion rules cap the multiplier at 10x. Whether the cap applies to free bets with no wagering condition is not established in the same guidance, and the offer terms of each operator are the only source.

The fourth is the everyday product — the in-play markets, the bet builder, the live streaming, the cash out, the price boosts. The sign-up offer is a way in; the everyday product is what the customer is buying. A brand with a thin in-play book or no live streaming on the sports a customer follows will not be worth a generous sign-up offer for long.

The 10x cap, in plain terms

A £10 bonus at 50x wagering required £500 of betting before any winnings were withdrawable; under the 10x cap, no more than £100. The cap is the headline change from 19 January 2026 and it is the reason offers on the licensed market now look more modest than they did two years ago. The cap sits on the multiplier, not on the size of the bonus: a £100 bonus with a 10x multiplier is the new ceiling of what any Commission-licensed brand can ask a customer to bet through.

The cap does not change the arithmetic of the free bet. A free bet whose stake is not returned is worth, on average, the free-bet amount multiplied by (decimal odds minus one), divided by those odds, multiplied by the payout share of the market it is spent on. The market’s margin eats the offer: a free bet at 5/1 (6.0) on a football match with a 6% margin is worth less than the same free bet on a market with a 3% margin, because more of every pound bet is kept by the bookmaker.

Mixed-product promotions

The same change banned mixed-product offers. An offer that requires a customer to gamble on two or more product types — betting, casino, bingo, lottery — to claim a reward is no longer permitted. A bookmaker can still run a sports free bet on a sports deposit; it cannot attach free spins, casino credit or bingo tickets to that offer. The effect is to put the betting bonus and the casino bonus in separate lanes, and the customer who only bets on sport now sees the sports offer on its own terms.

What a wagering requirement does to an offer

A wagering requirement is the part of an offer most often under-described. The number is the multiplier on the bonus — bet the bonus amount that many times over, at the minimum price the terms state, before any winnings turn into cash. The maths is the part the headline hides.

Take a £20 bonus at a 4x wagering requirement, with a minimum price of 1/2 (1.5). The required turnover is £80 — twenty pounds of bonus, four times over. At a stake of £5 per bet, sixteen qualifying bets are needed; at £10 a bet, eight. Each bet must be at odds of 1.5 or above. The bonus itself is not paid back with a winning qualifying bet: the qualifying bets are real-money stakes, paid from the customer’s own deposit, and the bonus is the reward for clearing them. A 4x requirement is light against the 10x cap. A 10x requirement is the cap; anything stated above 10x on a Commission-licensed site is not compliant.

The cost of clearing the offer is the expected loss on the qualifying turnover at the margin of the market the customer bets on. On a Premier League 1X2 market with a 5% margin, £80 of qualifying bets at the average margin costs £4 in expected value. On a market with a 9% margin — tennis outrights, some novelty markets — it costs £7.20 on the same turnover. The same bonus, cleared on a different market, is worth a different amount of real money.

The honest summary: a wagering requirement of 4x to 10x on a bonus of modest size is the kind of offer to read carefully rather than dismiss. A wagering requirement above 10x is not on a GB-licensed site in 2026. A bonus with no wagering requirement is the cleanest of all, because the only cost of the offer is the qualifying bet and the free-bet stake-not-returned.

A worked example: a £20 bonus at 4x

Required turnover = £20 × 4 = £80. Bets at £5 a stake: sixteen. Minimum price for each bet: 1/2 (1.5) on the operator’s own terms. The expected cost of clearing the offer, on a market with a 5% margin, is £80 × 0.05 = £4. The bonus is paid at the end; the qualifying bets pay out on their own merits. The customer’s position after clearing is the bonus minus the expected loss on the turnover — a positive figure on a market with a thin margin, a smaller positive figure on a market with a fat one. The exact figure depends on the bets the customer places and the prices they take; the £4 is the expected cost on a representative market.

This is a band, not a point. The same £20 bonus, cleared at the same 4x requirement but on a 9% market, costs £80 × 0.09 = £7.20 in expected value. On a 3% market, £2.40. The same offer, the same bonus, the same multiplier, three different costs.

Calculating the value of a free bet

The free bet is the most common reward and the most often misread. The arithmetic is short and unforgiving.

For a free bet whose stake is not paid back, the expected value of the free bet is the free-bet amount multiplied by (decimal odds minus one), divided by those odds, multiplied by the payout share of the market. A £10 free bet at 5/1 (6.0) on a market with a 95% payout share is worth £10 × (6 − 1) ÷ 6 × 0.95 = £7.92 on average. A £10 free bet at even money (2.0) on the same market is worth £10 × (2 − 1) ÷ 2 × 0.95 = £4.75. The longer the price, the higher the expected value, because the stake-not-returned haircut is a smaller share of the return.

The market’s margin is the part the customer cannot choose. A free bet at 5/1 (6.0) on a market with a 90% payout share is worth £7.50, against £7.92 on a 95% market. The same free bet, the same price, a different market, a different value. Football outrights in major leagues sit around the 95% mark on the 1X2 at the bigger brands; tennis match winner markets and outrights sit lower.

The free bet’s expected value is the average over many bets at the same price on the same market. No single bet pays £7.92; the bet either wins or it does not. A bettor who spends a £10 free bet on a 5/1 shot will either collect £50 of profit or nothing, and the average over many such bets converges on the figure above.

A free bet whose stake is paid back is a different product. A £10 free bet at 5/1 (6.0) where the stake is returned pays £60 on a win and is worth, on a 95% market, £10 × 6 ÷ 6 × 0.95 = £9.50 on average. The stake return adds the value of the stake to the value of the profit, and the offer looks larger for the same headline. The operator’s terms state whether the stake is returned; a “free bet” in the British market usually does not return the stake, and that wording is the one to read for.

Where the Commission’s 10x cap meets the free bet

The cap on wagering requirements is a separate question from the free bet’s expected value. A free bet with no wagering condition is a credit that can be spent once on a market; the winnings (or losses) are the customer’s. A free bet with a wagering condition — the customer must bet the winnings a stated number of times before they become cash — is a different product, and the cap sits on the multiplier on those winnings.

Whether the 10x cap applies to free bets with no wagering condition is not established in the same guidance. The honest reading is that the cap sits on bonuses with a wagering requirement, and the operator’s own terms are the source for what any specific free bet asks of the customer.

The £150 financial vulnerability check

Since 28 February 2025, a licensed remote betting operator must run a public-record check on a customer whose deposits minus withdrawals exceed £150 in a rolling 30-day window. The check looks at public records — bankruptcies, county court judgments, individual voluntary arrangements — and is not a credit reference check and not an income check. It is a quick automated sweep, and most customers pass without ever noticing it.

The £150 is a low threshold. A customer who deposits £5 a day for thirty-one days, with no withdrawals, passes it. A customer who deposits £150 in a single weekend, after a run of withdrawals, passes it. The check is the first of a staged plan; financial risk assessments (the “affordability checks” of the press) were announced in a Commission article of 7 July 2026, with a staged rollout and no start date. The honest framing is “announced, staged, no start date”, and the page does not write that they are in force.

A customer asked to provide source-of-funds information is being checked under the money-laundering rules, which sit alongside the betting licence. The operator sets its own threshold for the request; the rules do not fix a number. A request at higher spend is normal under the regime and is not a sign that anything is wrong with the customer’s account.

The statute: what a Gambling Commission licence does

A Gambling Commission licence is required at the point of consumption. The Gambling (Licensing and Advertising) Act 2014 amended the Gambling Act 2005 so that 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. The licence categories the comparison sits inside are remote general betting standard (real events) and the related categories for virtual events, pool betting and the betting intermediary licence that covers betting exchanges.

The Commission’s public register is the test. It can be searched by business name, trading name, domain or account number, and the result is the whole answer to whether a brand holds a licence for the activity in question. A licensed brand can use .com or .co.uk; the domain proves nothing. The Commission does not licence a single brand as “the only” licensed one. There is no state monopoly and no cap on the number of licences. The retailers in the comparison sit on the public register under the licence numbers above; the page does not print a count of licensed operators without an access date.

Section 33 of the Gambling Act 2005 is the offence: providing gambling facilities in Great Britain without the licence the Act requires, punishable on summary conviction by up to 51 weeks’ imprisonment, a fine up to level 5, or both (six months in Scotland). The offence is aimed at the operator. The Commission’s enforcement is disruption, not blocking: cease-and-desist notices, work with registrars, hosts and payment providers, search-engine referrals. Court-order DNS blocking powers have been granted or are about to be granted; the page does not write that ISP blocking is in operation.

Northern Ireland is outside the 2005 Act. The Act covers Great Britain — England, Scotland and Wales — and a separate, older law applies in Northern Ireland. The page writes “GB-licensed” or “Great Britain licence”, not that a GB licence regulates Northern Ireland.

Financial spread betting is regulated by the Financial Conduct Authority, not the Commission, and Spreadex’s homepage makes that split clear: the FCA for spread betting, the Gambling Commission for fixed-odds betting. The same brand carries two regulatory licences because the products are different. A bookmaker licensed for spread betting is not licensed for fixed-odds betting by the FCA; the fixed-odds licence comes from the Commission.

Verification before the first bet

A licensed operator verifies the customer’s name, address and date of birth before the first deposit or the first bet. The check has been mandatory since 7 May 2019 and includes free bets and bonuses — there is no way to claim a sign-up offer without the identity check. Anonymous play at a licensed site is not available. A customer who prefers to bet without that check is not served by the licensed market; they are served by the offshore market, and the offshore market does not carry the Commission’s protections.

General Betting Duty

General Betting Duty is the operator’s tax on gross profits from betting, currently 15%. From 1 April 2027 a new remote betting rate of 25% applies within it; remote bets on UK horse racing, bets on self-self-service betting terminals in licensed premises, pool betting and in-person betting stay at 15%. The player pays no tax on betting winnings in Great Britain; the duty sits on the operator, not on the customer. Whether operators pass duty on through their odds is not established, and the page does not write that the player is charged duty. The Commission’s statutory levy is a separate charge.

Spread betting has its own rates under the same regime: 3% on financial spread betting and 10% on other spread bets. The split is the reason a brand like Spreadex can run fixed-odds betting under the Commission and spread betting under the FCA on the same platform.

Responsible gambling: GAMSTOP, deposit limits and the help available

GAMSTOP is the national multi-operator online self-exclusion scheme, mandatory for online operators since 31 March 2020. A customer who signs up to GAMSTOP is excluded from every licensed online operator for the period they choose: 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 offline self-exclusion service.

Deposit limits are the customer’s tool. A licensed operator must offer a gross deposit limit on a fixed time frame; the first changes have applied since 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 for betting; the limit is the customer’s choice, and the operator must offer the tool.

The help line is GamCare, which runs the National Gambling Helpline. GambleAware funds treatment and education. The NHS runs gambling clinics. Gamblers Anonymous runs peer-support meetings. The page lists them as the routes a customer uses; it does not adjudicate between them.

A brand’s safer-gambling tools are the visible version of the same duty. DAZN Bet’s help pages describe deposit limits, loss limits and wagering limits as the three tools it offers, alongside time-out and self-exclusion. Other brands offer the same trio; the page does not claim a brand is unique in offering them, because every licensed operator is required to.

The offshore contrast

An unlicensed brand is not bound by any of this. No GAMSTOP coverage at the operator’s site, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld, no 10x bonus cap, no £150 vulnerability check, no verification before the first deposit in the same form. A customer with a GAMSTOP exclusion who opens an offshore account has stepped outside the British self-exclusion regime; the regime cannot reach them there.

The honest framing is licensed checks, limits, GAMSTOP coverage, the bonus cap, and verification before the first bet, set against none of those protections and possible loss of funds. Neither is “the safe choice” by default; the licensed market is the regulated market, and the unregulated market is not a parallel offer but a different one.

The ten brands, reviewed

What follows is a review of each brand in the comparison set. The reviews are built around the offer terms each operator publishes and the licence each operator holds. They are not endorsements, and they are not advertising. The verdict at the end of each is the page’s own reading of the offer against the rest of the comparison, and the question it answers is the one the block above it actually opened.

Unibet

Unibet has been operating since 1999, and the UK site is run by Platinum Gaming Limited, Gibraltar, under Gambling Commission account 45322. The sports welcome offer is a £40 free-bet package on a £20 qualifying bet at minimum odds of 2.0 (1/1); the free bets expire within 7 days of issue, and the qualifying deposit is on a debit card or instant bank transfer. The product around the offer is dense: Bet Builder, daily Uniboosts, live streaming through Unibet TV, in-play betting, Best Odds Guaranteed on horse racing, Cash Out on thousands of markets.

The cost of the offer is the £20 qualifying stake plus the stake-not-returned haircut on the free bet. A £20 free bet on a 5/1 (6.0) shot at a 95% market is worth £15.83 on average; on a 90% market, £15.00. A £20 free bet at evens (2.0) on the same markets is worth £9.50 or £9.00. The longer the price, the better the free bet performs; the thinner the market margin, the better again. Unibet’s Best Odds Guaranteed on horse racing is the operator’s way of paying the customer the bigger of the price taken and the starting price, and it is the product feature that pays the everyday punter most reliably. For a customer with a debit card, willing to bet at 1/1 or longer, the offer is a fair entry to a deep product. The seven-day expiry is the trap to plan around.

Paddy Power

Paddy Power’s UK site runs under PPB Counterparty Services Limited, on Gambling Commission account 39439. The sign-up offer terms vary by channel and date, and the App Store listing leans on the everyday product: Bet Builder+, Popular Bet Builders, Super Sub, expanded Win More markets, player and acca stats. Super Sub is the distinctive product — a bet on a selected player rolls over to the replacement if the player is substituted, which softens a common loss on football player markets. Bet Builder+ is the same-game multi tool that combines markets from one event.

Paddy Power’s marketing has long been louder than the offer headline, and the welcome offer is best checked in-app at the point of registration, where the qualifying terms and the free-bet expiry are stated in full. The everyday product is the case for the brand: the markets are broad, the in-play book is deep, and Super Sub is a feature the customer uses. For a customer whose betting is dominated by football, the roll-over feature and the Win More markets are the reasons to look past the headline.

Copybet

Copybet runs under Copybet UK Limited on Gambling Commission account 53774. The product leans on accumulators: an Acca Booster that pays up to a 100% cash bonus on accas of at least 3 selections, and a Daily Profit Boost of up to 15%. The “copy” in Copybet is the social feature: customers can follow other customers’ bets, and the platform is built around tipsters and their followers.

The cost of an acca insurance or acca booster offer is the margin of the underlying legs. A six-fold acca at average margins of 6% per leg carries a combined margin of around 31%, and a 100% boost on a winning acca pays the customer’s stake plus the boost, less the margin. The longer the acca, the higher the boost, the fatter the margin. The honest reading of an acca booster is that it pays more on longer accas where the margin has already taken a larger bite. For a customer whose betting is already acca-heavy, the boost is welcome; for a customer pricing single bets, the product is not built for them.

London Bet

London Bet is published by Thistle Bet Limited and states it is licensed and regulated in the UK on Gambling Commission account 66162. The App Store listing for the operator carries a 17+ age rating. The offer details are not in the same source as the licence: the customer checks the operator’s own terms for the current welcome package, the qualifying bet, the minimum price, the expiry and the payment-method restrictions.

London Bet is one of the smaller brands in the comparison set, and the product is best checked in-app or on the operator’s own page before a deposit. The licence is the floor; the offer and the everyday product are the case for choosing the brand. For a customer who wants a smaller GB-licensed bookmaker, the comparison slot is the way in; the offer terms are the way to plan the deposit.

Betway

Betway’s UK and Ireland welcome offer is £40 in free bet tokens (4 × £10), credited on settlement of a first bet of at least £10 at minimum odds of 2.0. The free bets expire after 7 days, and debit card deposits only. The licence sits with Betway Limited on Gambling Commission account 39372.

The offer is a clean bet-and-get, and the cost is the £10 qualifying stake plus the stake-not-returned haircut on the four £10 free bets. On a 95% market at 3/1 (4.0), the four free bets are worth £28.50 on average; on a 90% market, £27.00. The debit-card restriction is the part to plan around: an e-wallet deposit will not qualify, and a customer who prefers to pay by bank transfer should check the operator’s own list. For a customer with a debit card and a market in mind, the offer is plain and the seven-day expiry is the only thing to watch.

10bet

10bet’s app advertises a 100% up to £50 betting bonus for UK sign-ups, with daily free bets and free spins in the app. The licence sits with Blue Star Planet Limited on Gambling Commission account 43173. A “100% up to £50” headline is a matched deposit-style offer on the betting side, and the customer checks the operator’s terms for the wagering requirement, the minimum price and the expiry.

The wagering requirement is the number to read for. Under the 10x cap, the bonus turnover is the bonus amount multiplied by the operator’s stated multiplier, up to 10x. A £50 bonus at 4x is £200 of qualifying turnover; at 10x, £500. The free spins are a separate product, and under the mixed-product ban they are no longer attachable to the sports offer — the customer who sees free spins in the app should check whether they are part of a separate casino offer rather than a tied-in promotion.

BetVictor

BetVictor’s app advertises regular price boosts, acca offers and free bets on selected events, with welcome offers shown in the app and governed by the customer terms. The licence sits with BV Gaming Limited on Gambling Commission account 39576. The brand is one of the older names in the British market, and the everyday product is the case for choosing it: deep horse-racing markets, competitive football prices, and an in-play book that holds up.

The welcome offer is best checked in-app at the point of registration, where the qualifying terms and the free-bet expiry are stated in full. The price boosts and the acca offers are the everyday product, and the customer who bets horse racing and football is the customer the brand is built for. For a customer pricing the everyday product, BetVictor’s competitive position is the case; the sign-up offer is the entry to it.

Hollywoodbets

Hollywoodbets’ sports welcome offer is a stake-back as a free bet of up to £30 on the first qualifying losing accumulator, with a stake of £10+, 3+ legs, odds of 4/1 or greater, settled within 7 days; one free bet per customer. The licence sits with Hollywoodbets International UK Limited on Gambling Commission account 53028.

The offer is a stake-back, not a bet-and-get: the customer must lose the first acca to claim the free bet. The cost is the £10 qualifying stake; the upside is the £30 free bet on a losing bet. The 4/1 minimum and the 3+ legs are the qualifying conditions; a single or a double does not qualify. The 7-day window is the deadline for both the qualifying bet and the free bet. For a customer who bets accas anyway, the offer is a hedge against the first one losing; for a customer who bets singles, the offer is not built for them.

BetUK

BetUK’s sports welcome offer is four £10 free bets (two football accumulators of 4+ selections and two multiples of 2+) on a £10+ deposit and a sports bet within 7 days of registering; opt-in is required. The licence sits with LeoVegas Gaming PLC on Gambling Commission account 39198.

The offer is a token set with a product preference: two of the four free bets are for football accumulators of 4+ selections, and two are for multiples of 2+. The free bets are valid for 7 days. For a customer who bets football accas, the offer matches the betting style; for a customer who bets singles, the offer is constrained. The 7-day window on the qualifying bet is the part to plan around, and the opt-in is the part to tick.

Sky Bet

Sky Bet’s welcome offer 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 licence sits with SBG Sports Limited on Gambling Commission account 67370.

The 5p minimum stake is the floor: a customer can qualify the offer for a 5p bet, and the rest of the value is the free bets. On a 95% market at 3/1 (4.0), the three free bets are worth £21.38 on average; on a 90% market, £20.25. The deposit floor of £5 is the lowest in the comparison. For a customer who wants to test a bookmaker with the smallest possible qualifying stake, the offer is the cleanest entry in the comparison; for a customer with a normal betting bank, the offer is a smaller version of the same bet-and-get shape.

The arithmetic of clearing a sign-up offer

The worked figure for the comparison sits on a representative offer: a £20 bonus at 4x wagering, with a minimum price of 1/2 (1.5), placed on a market with a 5% margin. Required turnover = £20 × 4 = £80. Bets at £5 a stake: sixteen. Bets at £10 a stake: eight. The expected cost of clearing, on a market with a 5% margin, is £80 × 0.05 = £4. The same offer on a 9% market costs £7.20; on a 3% market, £2.40. The offer is worth between £12.80 and £17.60 in net terms, depending on the market the customer uses to clear it.

The result is a band, not a point. The honest way to write the offer is “around £13 to £18 of net value after clearing, depending on the market” — the lower end on a fatter market, the higher end on a thinner one. The same offer, with the same headline, is worth a different amount of real money to a real bettor.

The 10x cap is the multiplier ceiling. A £20 bonus at 10x wagering, on the same £5 stake, is £200 of qualifying turnover across forty bets; the expected cost at a 5% margin is £10, and the offer is worth between £10 and £20 of net value on the same market range. A bonus with no wagering requirement is the cleanest: the cost is the qualifying bet and the stake-not-returned haircut on the free bet, and the offer is worth the free bet’s expected value plus the qualifying bet’s result.

The 19 January 2026 cap is the reason the band above sits where it does. A 50x offer on a £10 bonus — £500 of qualifying turnover at 5% margin, costing £25 — is no longer on a GB-licensed site. The cap pulled the high end of the band down by a factor of five, and the offers on the licensed market are now modest in turnover terms.

What to check on a bookmaker before claiming

A licence is the floor. Five checks live above it.

First, the offer terms on the operator’s own page, at the point of registration. The minimum stake, the minimum price, the qualifying market, the payment-method restriction and the expiry are stated in the small print; the headline is the headline, and the small print is the offer. A bonus code printed at the foot of an email is a routing token, not a value, and the value is the offer behind it.

Second, the licence number on the Commission’s public register. The register can be searched by business name, trading name, domain or account number. The result is the whole answer to whether a brand is licensed for the activity in question. A licensed brand may use .com or .co.uk; the domain proves nothing.

Third, the everyday product. The sign-up offer is the entry; the in-play book, the bet builder, the live streaming, the cash out, the price boosts are the product. A thin in-play book or no live streaming on the sports the customer follows will not be worth a generous sign-up offer for long.

Fourth, the payment methods. Credit cards are banned for gambling in Great Britain, including credit-card-funded payments through an e-wallet. Debit cards and bank-based payments are not covered by that ban. Several brands restrict welcome offers to debit card deposits; the customer checks the operator’s list before depositing by an e-wallet.

Fifth, the safer-gambling tools. Every licensed operator offers deposit limits, time-out and self-exclusion; most offer loss limits and wagering limits. GAMSTOP is the multi-operator self-exclusion, and a customer who has signed up to GAMSTOP is excluded from every licensed online operator. A brand without these tools is not licensed in Great Britain.

Frequently asked questions

How is a promo code used on a betting site?

A promo code is typed into the registration form, the deposit screen or the bet slip where the operator’s own page indicates, and the offer is unlocked once the qualifying conditions are met. Some operators no longer use codes at all; the offer applies automatically once the qualifying bet is placed. A code is a routing mechanism, not a value, and the value of the offer is the same whether the customer types it in or not.

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

Since 19 January 2026, the Gambling Commission has capped wagering requirements on bonuses at 10x. A £10 bonus at 50x required £500 of betting before any winnings were withdrawable; under the cap, no more than £100. The cap is the ceiling on the multiplier; the offer terms of each operator state the actual multiplier on each bonus, and an offer above 10x is not on a GB-licensed site.

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

Minimum odds are the shortest price the qualifying bet must be at to unlock the offer — 1/1 (2.0) is the common floor. The wagering requirement is the multiplier on the bonus the customer must bet through before winnings become withdrawable cash. A £20 bonus at 4x wagering is £80 of qualifying turnover, across sixteen £5 bets or eight £10 bets, each at or above the minimum price. The two numbers are the shape of the offer.

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

A free bet is a token, not a cash stake, and the operator credits the winnings only — a £10 free bet at 3/1 (4.0) returns £30 of profit, not £40. The stake return is the difference between a free bet and a real-money bet, and the British market treats them as different products. Some offers refund the stake on a free bet win; the operator’s terms state whether the stake is returned, and the customer reads for that line.

Can a bet on sport be tied to a casino bonus under the Commission’s promotion rules?

No. Since 19 January 2026, mixed-product promotions are banned. An offer that requires a customer to gamble on two or more product types — betting, casino, bingo, lottery — to claim a reward is not permitted. A bookmaker can run a sports free bet on a sports deposit; it cannot attach free spins, casino credit or bingo tickets to that offer. The sports bonus and the casino bonus are in separate lanes.

How can it be checked that a bookmaker holds a Gambling Commission licence?

The Commission’s public register can be searched by business name, trading name, domain or account number. The result is the whole answer to whether a brand is licensed for the activity in question. The register is the test; the licence numbers in the comparison above are the entries on the register that the customer can look up directly.
