A punter who already has an account with a UK bookmaker is the audience the marketing keeps promising the most: free bet tokens that drop into the account on a Friday night, acca insurance for the Saturday card, price boosts on a 3pm kick-off. The promise is real and so are the conditions pinned to it. The Gambling Commission’s promotion rules in force since 19 January 2026 cap any wagering requirement on a bonus at 10x, and they ban offers that push a customer between two product types — betting and casino together, betting and bingo, that kind of bundle. Those are the two rules every existing-customer offer in Great Britain has to live inside, and they shape what is on the table more than any single brand’s headline price. This page works through what the offer is, what it costs the bettor, and which UK bookmakers run the kind of recurring value a returning customer can actually use. Figures are checked as of the register snapshot below; offer terms change and a customer’s own bookmaker account is the version that pays out.

Last checked: 27 October 2026 against the Gambling Commission’s public register of operating licences.

The Landscape: What Counts as an Existing-Customer Offer

The sign-up bonus gets the column inches, and the existing-customer offer is the workhorse of the relationship. Three shapes cover most of what a UK bookmaker will run for a returning customer, and each has its own arithmetic. A free bet is a token whose stake is not paid back when the bet wins — £10 free at odds of 3.0 returns £20 in profit, not £30. A price boost, also called enhanced odds or acca boost, raises the price the bookmaker offers on a particular outcome; the customer still pays the stake, and the extra fraction is paid in cash or in a free bet depending on the term. Acca insurance refunds the stake as a free bet when one leg of a qualifying accumulator lets the punter down, usually with a cap and an expiry that decide whether it is worth claiming. Cashback returns a percentage of net losses over a window, again as a free bet or as cash.

The thing to keep in mind across all three is the difference between stake-returned and stake-not-returned. A free bet token is stake-not-returned as a rule; a price boost can pay either way, with the difference written into the small print. The reader who reads “£30 in free bets” as £30 of profit is the reader the marketing writer has been waiting for all day.

What the Free Bet Is Really Worth

The honest number for a stake-not-returned free bet on a single outcome at decimal odds *o* and a market payout share of *p* is the free bet amount multiplied by (o − 1) ÷ o, then multiplied by *p*. The bookmaker’s margin sits inside that *p*, so a market at 95% payout share gives a fairer price than one at 90%, and the free bet’s expected value tracks the difference. Sticking to markets with low margins — the top-flight football 1X2 close to 105% overround is fine; exotic in-play markets and novelty props are usually tighter — is how a careful customer pushes that figure up. The thing the marketing never says: the same £10 free bet on a six-fold acca of 1.20 shots is worth materially less than £10 free on a single Premier League match at odds of 3.0, because the overround compounds with every leg.

What the Acca Boost Really Adds

An acca boost applies a multiplier to the price of a winning accumulator: 10% extra on a four-fold is the common starting shape, 100% on a fifteen-fold is the far end. The catch is the minimum odds per leg, the maximum boost in pounds and the cap on qualifying stake. The honest framing is to read the boost as a percentage of the price, then check whether the price would have been a reasonable bet without it — a 10% boost on a 4/1 acca is still a 4/1 acca, and 4/1 accas still miss more than they land. The boost pads the winner; it does not cancel the miss.

Statute and Jurisdiction: What the Gambling Commission Actually Says

The Gambling Commission is the regulator. It is a non-departmental public body sponsored by the Department for Culture, Media and Sport, and it licenses the whole commercial market in Great Britain under the Gambling Act 2005 — England, Scotland and Wales. Northern Ireland sits outside the 2005 Act and has its own older law, so a “GB licence” is the right phrase and an unqualified “UK licence” overstates the reach. The Commission has run since the 2005 Act came into force and the modern shape of remote regulation dates from the Gambling (Licensing and Advertising) Act 2014, which made a Commission licence compulsory for any bookmaker whose remote facilities are used in Great Britain, no matter where the operator is based. A Curaçao, Maltese or Gibraltar licence is a licence under that jurisdiction’s own regime and does not stand in for the British one.

The Commission’s public register is the test. Anyone can search by business name, trading name, domain or account number and see whether a brand holds a licence, what kind of licence it is, and which legal entity stands behind it. The search is the only way to be sure, because a licensed operator can run a .com site as easily as a .co.uk one, and the domain proves nothing on its own. Several well-known British brands run under one legal entity — Coral and Ladbrokes share LC International Limited, Paddy Power and Betfair share Flutter — so the licence a reader looks up is the entity, not the trading name.

Promotion Rules Since 19 January 2026

Two promotion rules landed on 19 January 2026 and they are the spine of this page. The first caps any wagering requirement attached to a bonus at 10x — a £10 bonus at 50x wagering is no longer permitted, because the £500 of qualifying bets it would require exceeds the £100 ceiling the cap sets. The cap is on the wagering multiple itself, so a 9x program is in and an 11x program is out. The second rule bans mixed-product promotions — an offer that requires a customer to gamble on two or more product types, betting plus casino, betting plus bingo, betting plus lottery, is banned outright. “Bet £10 on football to unlock free spins” is the banned shape.

What the rules do not settle is whether the 10x cap applies to a free bet with no wagering condition attached at all — the rule talks of “wagering requirements on bonuses”, and a free bet that pays out as cash the first time it wins is not a bonus with a wagering condition. The Commission’s published line on this is not established and the terms on each offer are what governs. What is also not established is any cap on the money value of a bonus: the cap is on the multiple, not on the headline amount. A £200 bonus at 5x wagering is in; a £5 bonus at 50x is out.

Identity, Age and the £150 Vulnerability Check

The minimum age at a licensed operator is 18. Since 7 May 2019 name, address and date of birth have to be verified before the first deposit and before the first bet, including a free bet or a bonus — there is no anonymous play at a licensed site, and a free-bet-token drop into a new account requires the same proof as a £100 deposit. Since 30 August 2024 a financial vulnerability check applies once a customer’s net deposits in a rolling 30-day window exceed £150 — the £150 trigger took effect on 28 February 2025 — and the check is a public-records look for county court judgments, bankruptcy and similar markers, not an income check and not a credit reference check.

Financial risk assessments — the affordability checks the press calls “affordability checks” — were announced on a staged timeline in a Commission article of 7 July 2026 with no start date. The honest phrase is “announced, staged, no start date”; calling them “in force” is wrong until the Commission says otherwise. The £150 vulnerability check is the live version of the protection today, and it triggers on net deposit, not on stake, so a customer who deposits £500 and withdraws £400 in a month does not trip it.

General Betting Duty and the Player’s Tax Position

The player pays no tax on betting winnings in Great Britain. General Betting Duty is the bookmaker’s tax on gross profits, and it sits at 15% today across most of the market. From 1 April 2027 a new remote betting rate of 25% applies within General Betting Duty, while remote bets on UK horse racing, pool betting, bets on self-service betting terminals in licensed premises and in-person betting stay at 15%. Until that date the remote rate holds at 15%. Whether operators pass the duty on through their odds is not established — the marketing never says, and the pricing is what the pricing is. Spread betting has its own duty rates — 3% on financial, 10% on other — and is a different product, not a free-bet-friendly alternative to a fixed-odds book.

Safeguards: What the Player Has and Where the Help Lives

GAMSTOP is the national multi-operator online self-exclusion scheme and it has been a mandatory licence condition for online operators since 31 March 2020. Every brand on this page takes part. A self-exclusion can run for six months, one year, five years, or five years with auto-renewal, and 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; the high-street bookmaker shops run on a separate self-exclusion register, so the two are not interchangeable.

Deposit limits sit on the customer side rather than the state side. Remote Technical Standards 12 require operators to offer a gross deposit limit on a fixed time frame — daily, weekly or monthly — and the customer sets the level. The first phase of changes has applied since 31 October 2025, a second phase was postponed to 30 September 2026, and whether that second phase is live is not established. There is no state-set ceiling on stakes or losses in sports betting; the operator’s own maximum-stake rule on a particular market, the bookmaker’s right to restrict a customer, and the customer’s own deposit limit are the layers between a stake and the rest of the household budget.

Help outside the operator sits with GamCare, which runs the National Gambling Helpline, with GambleAware, with the NHS gambling clinics and with Gamblers Anonymous. A customer who feels their betting is sliding outside what they planned can reach GamCare on the helpline or live chat without going through the bookmaker first, and self-referral is the usual route.

Bonus Mechanics and the 10x Cap in Practice

The 10x cap on wagering is the most concrete piece of consumer protection the Commission has put in force recently, and it works on a simple idea: a bonus is paid in the customer’s account as a notional balance, and a wagering requirement is the number of times that balance has to be staked before the balance and any winnings from it can be withdrawn. At 10x, a £10 bonus needs £100 of qualifying bets before withdrawal; at 50x, the same bonus needed £500 of qualifying bets, and most customers did not get there. The cap closes the gap.

The minimum odds for each qualifying bet matter, because the cap is on the multiple, not on the position. A £10 bonus at 10x on bets at minimum odds of 1/2 (decimal 1.50) needs ten £10 bets and gives back whatever is left of the bonus after the bookmaker’s margin has run over those ten bets. The same £10 bonus on bets at minimum odds of 4/6 (2.66) needs fewer qualifying bets to clear the headline turnover, because the customer can stake less in absolute terms to release the same amount — though the customer’s exposure to losing runs is higher per bet, and the marketing never advertises that trade-off.

Worked Example: Clearing a Hypothetical Bonus

Take a notional £20 bonus with a 5x wagering requirement on bets at minimum odds of 4/5 (decimal 1.80). The required turnover is £20 multiplied by 5, which is £100 of qualifying bets. At a £10 stake per bet that is ten qualifying bets; at a £20 stake it is five. Assuming only the bonus amount is wagered, the expected cost of clearing those bets is the turnover multiplied by the margin of the market the bonus is being cleared on — for a market with a 5% margin, that is £100 multiplied by 5%, or £5, before the £20 bonus is added back. The honest framing is that the bonus is worth the headline amount minus the cost of clearing it, which on these inputs lands at roughly £15 in expected value, give or take the margin the customer’s chosen market actually carries. The exact figure moves with the bookmaker’s margin on the markets the customer plays, and a punt on a tight Premier League 1X2 is cheaper to clear than a punt on an exotic in-play novelty prop.

What the arithmetic shows is the gap between the headline number on the offer page and what lands in the account. A £10 bonus on a 50x program was worth the offering with £500 of bets back; on a 10x program the same £10 bonus is worth the offering with £100 of bets back. The reader who does the arithmetic on a 50x program and the same arithmetic on a 10x program understands the cap without anyone having to explain it.

The Ten Operators

The operators below are the ten reviewed in this comparison. They are listed in the order research gives them, and the order is not a ranking of offer quality — it is a sequence. The licences are checked against the Gambling Commission’s public register. The descriptions stick to what the operator’s own site or app states, and where a detail is not established for a brand the page says so.

BetTom: a Two-Pronged Sign-up and a Casino Hook

BetTom runs a 50% back as a 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, and full terms apply on both. The shape — sport on one side, casino on the other — is the exact construction the Commission’s mixed-product promotion ban is aimed at, and any operator still offering it after 19 January 2026 is offering it under whatever carve-out the operator reads into “mixed-product”. A returning customer who already has the account sees the daily boosts and the free spins the brand keeps running for the existing book, and the gambling decision is whether the casino half of the welcome offer is worth taking separately from the sports half.

The Commission’s account number for BetTom is 64959, and the licence is held by Bet Tom Limited against remote general betting standard (real events). The site is Bettom.com and the licence covers that domain. A punter who wants the cleanest version of the sports sign-up should look at the terms on the betting leg alone and treat the casino leg as a separate decision.

Coral: the £40 Free Bet Welcome and the Daily Reward Shaker

Coral’s sports welcome offer is a £40 free bet for a £20 qualifying bet at minimum odds of 2.0 (1/1), with the free bets issued within 7 days of the qualifying bet settling and expiring 7 days after issue. The offer is for new GB customers using a debit card or instant bank transfer; the qualifying payment methods are listed on the Coral site, and Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly are among the options a returning customer can fund the account with. On the existing-customer side Coral 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.

Coral’s licence is held by LC International Limited under Gambling Commission account 54743 against remote general betting standard (real events) and remote betting intermediary. The Commission’s register lists both categories, which is the right shape for a brand that also runs an exchange-style product. The free daily Reward Shaker is the kind of recurring value a returning customer is actually looking for — it lands in the account on a regular cadence without the customer having to qualify a deposit, and the small print on the day’s prize is what governs the payout.

Dabble: a £10-for-£10 Welcome with a Clear Stake-Not-Returned Line

Dabble’s welcome offer is “Bet £10, Get £10 in Free Bets” on a first deposit, with minimum odds applying, a 7-day expiry on the free bets and the stake not returned when the free bet wins. The phrase “stake not returned” is the right one for a returning customer who has had the offer before and is back to look at the daily product — it tells the reader the free bet is stake-not-returned, so a £10 free bet at odds of 3.0 returns £20 in profit, not £30. The 7-day expiry is short by the standards of the bigger brands and is the thing to keep in mind if the customer is sitting on a token waiting for the right race.

Dabble’s licence is held by Dabble Sports UK Ltd under Gambling Commission account 65677 against remote general betting standard (real events). The small print on the offer page provides the details on minimum odds and qualifying markets, with the Commission register confirming the site’s licence status.

Sky Bet: the £30-in-Three-Tokens Welcome

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 (2.0) or greater. The 5p minimum stake is a quirk of Sky Bet’s structure and is the part of the offer that does the heavy lifting in the marketing — a customer who deposits £5 and stakes 5p qualifies for the full £30 of free bets, which is an unusually small qualifying outlay for the headline number. The 1/1 minimum odds keeps the offer inside the same shape most sportsbooks use; the three-token split is a Sky Bet choice and is the reason a returning customer is sometimes holding one £10 token while the other two have been used or expired.

Sky Bet’s licence is held by SBG Sports Limited under Gambling Commission account 67370. The brand’s register entry details its licence for remote general betting, while the terms on the token series determine how the free bets behave when one is left in the account.

Kalooki Sportsbook: the Bank-Transfer Minutes Pitch

Kalooki Sportsbook is the bookmaker with the strongest claim on speed of withdrawal in this set — the site advertises instant withdrawals by bank transfer within minutes, Best Odds Guaranteed on UK and Irish horse racing, in-play betting, daily boosts and extra place races. The instant-withdrawal pitch is the headline and the rest of the product is the standard sportsbook package: pre-event, in-play, BOG on the racing product, daily boosts and the extra-place offers that have become a fixture on the Festival meetings. Kalooki is operated by Kelly Sports Book Ltd — the company number is 12938274 — and is licensed by the Gambling Commission under account 57730, with the licence running against remote general betting standard (real events). Kalooki is a GAMSTOP member.

The bank’s instant-withdrawal rail is the piece that matters to a returning customer who has won and wants the funds out today rather than tomorrow. It is also the kind of feature a customer should test with a small withdrawal before staking on it for a big one, because “instant” is a marketing word and the bank’s own processing time on a £500 transfer is what governs whether the funds are in the account before the weekend.

Sporting Index: the Fixed-Odds and Spread Combo Welcome

Sporting Index’s new-customer offer is a layered bundle that mixes fixed-odds free bets with spread-betting market tokens. 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, which is the term that catches a returning customer out — a customer who lays the qualifying bet early to lock in a profit does not unlock the bundle, and the bundle is the headline offer.

The shape is the right one for a brand that wants to give a customer a tour of the two products — fixed odds on the football, spread bets on the goals markets and the favourites — and the small print is what governs whether each of those tokens lands in the account and what the expiry is on each. Sporting Index’s licence is held by Sporting Index Limited under Gambling Commission account 27343 against remote general betting standard (real events). The brand is regulated for spread betting by the Financial Conduct Authority, and the Commission licence is what governs the fixed-odds side; the two regulators sit on different sides of the same product.

Copybet: the Acca Booster and the Daily Profit Boost

Copybet’s Acca Booster pays up to a 100% cash bonus on accumulators of at least 3 selections, and the brand runs up to a 15% Daily Profit Boost on top. The “up to” framing is the honest shape — the boost is on a sliding scale by the number of legs, and a three-fold pays a much smaller percentage than a fifteen-fold. The 100% cap on a fifteen-fold with each leg at 1/5 or better is the kind of headline a returning customer will hold for the Saturday card and the Champions League midweek.

Copybet’s licence is held by Copybet UK Limited under Gambling Commission account 53774 against remote general betting standard (real events). The brand’s own terms on the booster are what governs the sliding scale, with the register offering further licence verification.

QuinnBet: a 7-Day Free Bet on a Tight Odds 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; Trixies, Patents and Yankees are not. The Trixie/Patent/Yankee exclusion is the part of the term a returning customer will trip over — a customer who has been building Trixies for the Saturday racing will find the free bet is unusable on that combination, and the offer has to be worked into a different bet shape.

QuinnBet’s licence is held by QuinnBet (Gibraltar) Limited under Gambling Commission account 61011. The site is listed on the Commission register for remote general betting, and its specific odds and eligibility terms define the free bet’s value.

10bet: a 100%-Up-to-£50 Sign-Up

10bet advertises a 100% up to £50 betting bonus for UK sign-ups, plus daily free bets and free spins on the casino side. The 100% match is the headline, and the small print on the wagering requirement, the minimum odds and the expiry is what governs whether the bonus is worth taking. With the 10x cap in force since 19 January 2026, the operator’s own terms have to live inside that ceiling, and the £50 cap on the headline means a £50 deposit at 100% match turns into a £50 bonus with a £500 turnover requirement at 10x, give or take the qualifying stake.

10bet’s licence is held by Blue Star Planet Limited under Gambling Commission account 43173 against remote general betting standard (real events). You can verify this on the Commission register, and its specific wagering terms explain how the bonus conditions apply.

Smarkets: the SBK £60-in-£20 Welcome and the Exchange Bookmaker Pair

Smarkets also runs the SBK sportsbook, whose UK welcome offer is a £20 first deposit and a £20 qualifying bet at minimum odds of 3.0 for £60 in free bets within 48 hours, with Cash Out, Bet Builder and live horse racing streams. The 3.0 minimum odds on the qualifying bet is a higher bar than the 1/2 or evens most sign-ups run, and the £60 in free bets is paid in three tokens rather than as a single balance. Smarkets itself runs as a betting exchange under the betting intermediary licence.

Smarkets’ licence is held by Smarkets (Malta) Limited under Gambling Commission account 39173 against remote betting intermediary, and the Commission’s register reflects the exchange’s regulatory category rather than a standard bookmaker licence. The exchange and the sportsbook sit under the same legal entity, and a returning customer should check the Commission’s register for both the trading names and the entity.

Comparison: Existing-Customer Offers at the Ten Bookmakers

The table below sets the ten reviewed operators side by side. The licence column carries the Gambling Commission account number and the licence holder; the offer column on existing-customer value carries the recurring offer the brand runs for a returning customer, as the operator’s own terms state it. Where research has not established a recurring existing-customer offer for a brand, the cell reads no data — the absence is a statement the reader can act on, namely that the brand’s recurring value for existing customers was not visible in the inputs and is worth checking on the brand’s own page.

The table is not a ranking. A brand with no data in the existing-customer column is not a worse brand; it is a brand whose recurring existing-customer offer was not visible in the inputs the page is built on, and the brand’s own promotions page is the place to check. A returning customer who has already worked through a brand’s sign-up is the customer the Reward Shaker, the Acca Booster and the Daily Profit Boost are aimed at, and the brands in the third column are the ones with a visible recurring product in the inputs.

A Note on Offshore and Unlicensed Operators

The frame above is the frame for licensed operators. A bookmaker without a Gambling Commission licence that takes bets from a customer in Great Britain commits an offence under section 33 of the Gambling Act 2005 — on summary conviction up to 51 weeks’ imprisonment, a fine up to level 5, or both; six months in Scotland. The offence is aimed at the operator, not the customer who bets on the unlicensed site. The honest framing of the customer’s position is the loss of protections: no GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld, and no application of the 10x bonus cap or the £150 vulnerability check. The customer is not “safe” at an unlicensed site because the operator has a Curaçao or Malta licence — that licence is a licence under that jurisdiction’s regime, not under the British one, and the British regime is the one that gives the British consumer the protections the British regulator enforces.

Enforcement against unlicensed operators runs through cease-and-desist notices, search-engine referrals, work with registrars, hosts and payment providers, and DNS blocking powers the Commission has been given or is about to receive. None of that is “ISP blocking” in the live-network sense, and the framing on a customer-facing page should be that the Commission disrupts unlicensed operators rather than blocks them at the network layer. The honest line is that a licensed operator is the customer’s route to GAMSTOP, the £150 vulnerability check, the 10x bonus cap and the British dispute-resolution system; an unlicensed operator is none of those things, and the customer’s protection if funds are withheld is the customer’s problem.

Marketing Rules: The CAP Code, the ASA and the Under-25 Rule

The Commission does not license advertising; the ASA does. Broadcast advertising runs through the BCAP Code, non-broadcast through the CAP Code, and section 16 of the CAP Code is the rule the gambling marketing lives inside. The rule has three pieces the returning customer should know about: marketing must be socially responsible, must not be of strong appeal to under-18s, and no one who is or seems to be under 25 may be featured gambling or play a significant role in the advertisement — with an exception for marketing placed where a bet can be made directly, which is the betting-shop and the in-app piece. The rule concerns who may appear in the advertisement, not who may bet; the age at which a customer may bet is 18.

The “whistle-to-whistle” rule is an industry code rather than law — since 1 August 2019 betting advertisements have not been shown on TV from five minutes before a live sporting event to five minutes after it, before the 9pm watershed, with horse and greyhound racing excluded. The Premier League clubs’ withdrawal of gambling sponsorship from the front of matchday shirts is a voluntary agreement from the 2026/27 season, not a statutory rule; sleeves and hoardings remain. None of this changes a returning customer’s exposure to marketing, and the rules above are the rules the marketing runs inside rather than the rules the customer is exempt from.

Payment Methods at a Glance

The payment picture at a licensed UK bookmaker is set by three rules: no credit cards for gambling since 14 April 2020, including credit-card-funded payments through an e-wallet; debit cards and bank-based payments are not covered by the credit-card ban and are the usual rails; identity verification before the first deposit means no anonymous play. The list of payment methods at each brand is the list on the brand’s own deposit page, and Coral’s published list — Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport, Trustly — is a fair representation of what a licensed operator offers. The customer who finds a payment method they trust on the brand’s own page is the customer the brand’s payment rules are designed for.

Source-of-funds questions at higher spend are part of the money-laundering regime the operator runs inside, and they are not an offer the customer accepts or declines — they are a regulatory obligation. A customer who has been asked for three months pays more on the standard verification; a customer who has not been asked has either deposited less or has not hit the threshold the operator sets. Whether cryptocurrency deposits are accepted at a licensed UK bookmaker is not established in the inputs; the licensed operators’ published payment lists are the test.

What the Wagering Cap Means for a £10 Bonus

Putting the cap into numbers is the cleanest way to make the rule land. A £10 bonus at 50x wagering needed £500 of qualifying bets before the bonus and any winnings from it could be withdrawn — at £10 per bet that is fifty qualifying bets; at £25 per bet it is twenty. The 10x cap closes that gap: a £10 bonus at 10x wagering needs £100 of qualifying bets, at £10 per bet ten bets, and the operator’s own terms decide the minimum odds and the eligible markets. The headline number on the offer page stays the same; the cost to the customer of clearing the bonus falls by 80%.

The reader who has worked through a 50x program before knows what that 80% saves in time and in bets. A returning customer at a brand running a 5x program today is at the better end of the market, and a brand running a 9x program is at the inside edge of what is now permitted. A brand running an 11x program is operating outside the rules, and the Commission’s register and the operator’s own terms are the place to confirm the version the customer is being offered.

Minimum Odds and the Qualifying Bet

The minimum odds on the qualifying bet — usually 1/2 (1.50), 4/5 (1.80) or 1/1 (2.0) — are the part of the offer that decides whether a £5 free bet on the racing is a qualifying bet or not. A minimum-odds rule of 1/2 disqualifies odds-on shots only at the very short end; a minimum-odds rule of 4/5 disqualifies most of them. The honest framing for a returning customer is to check the minimum odds on the qualifying bet before staking, and to check whether the free bet has a separate minimum odds for the bet the free bet is used on. Two rules can sit on the same offer and a customer who qualifies the deposit at 1/2 then uses the free bet at 1/3 is in breach of the second rule.

The minimum-odds rule is also what the bookmaker’s margin compounds with. A free bet used at 1/2 carries a margin that is much wider than the margin at 4/5 or 1/1, and the expected value of the free bet falls with the odds it is used at. A punter who uses a £10 free bet on a Premier League match at odds of 3.0 gets a fairer price than the same punter using the same free bet on a six-fold acca of 1.20 shots. The bookmaker has priced the difference into the offer, and the customer’s job is to spot it.

A Reader’s Route Through the Offer Page

A returning customer who has just landed on a brand’s offers page has four things to read before claiming anything. The first is the qualifying bet — stake, minimum odds, eligible markets, expiry on the qualifying window. The second is the bonus balance — what lands in the account, whether the stake is returned with a win, and the form of the balance (free bet token, cash credit, casino credit). The third is the wagering requirement — the multiple, the eligible markets, the minimum odds per bet, the expiry on the wagering window. The fourth is the cashout rule — whether the bonus and any winnings from it are withdrawable, and what is left of them after the wagering is done.

A customer who reads those four sections before claiming the offer knows more about the offer than the marketing does. A customer who reads only the headline — “£30 free bets” — knows less than the marketing assumes. The first reading is the one that decides whether the offer is worth taking; the second reading is the one that decides whether the offer is worth keeping in the account for the Saturday card.

Where to Check the Licence

The Commission’s public register at the domain the regulator publishes is the test. The search accepts a business name, a trading name, a domain or an account number, and the search returns the licence categories, the licence holder and the trading names registered against that holder. A customer who finds a brand they are considering on the register knows the brand is licensed; a customer who does not find it knows to look elsewhere. The register is not a recommendation and a place in a comparison is not a licence — a brand on this page is licensed because the Commission’s register says so, not because the comparison has placed it there.

The Commission’s register also lists the categories the licence covers. A remote general betting standard (real events) licence covers sports betting on real events; a remote betting intermediary licence covers betting exchanges; a remote pool betting licence covers pool betting on horse and dog racing. The categories are not interchangeable and a brand licensed only for pool betting cannot run a sportsbook under that licence. The Commission’s register is the test of the categories as well as the licence.

What the Free Bet Returns at the Common Shapes

Putting the stake-not-returned rule into numbers is the cleanest way to see what a free bet actually pays. A £10 free bet at odds of 2.0 returns £10 in profit, not £20 — the stake is the £10 that was the free bet and is not paid back. A £10 free bet at odds of 3.0 returns £20 in profit, not £30. A £10 free bet at odds of 5.0 returns £40 in profit, not £50. The pattern is the same at every price: profit = free bet × (decimal odds − 1), return to the customer = profit only. A customer who reads the offer page as “£10 free bet at 3.0 returns £30” is the customer the marketing writer has been waiting for all day.

The same calculation on a stake-returned free bet — rarer, but used on some offers — gives a different answer. A £10 stake-returned free bet at odds of 3.0 returns £30 in cash: £10 stake plus £20 profit. The two versions of the same headline number — “£10 free bet” — return different amounts at the same odds, and the small print on the offer page is the test. The reader who checks the small print on the first offer of the day will check it on the second, and the second offer is where the customer catches the difference.

Reading the Commission Register: The Practical Steps

The register is at the Commission’s published domain, and the search accepts the four fields named above. The customer who types the trading name of the brand into the business-name field gets the licence holder, the account number, the licence status and the licensed trading names; the customer who types the domain into the domain field gets the same answer and a list of any other domains registered against that licence. The customer who types the licence number into the account-number field gets the same answer with the licence type front and centre. The search is free and does not require an account.

The honest use of the register is to check the brand before opening the account, and to re-check it if the customer has not used the brand for a while. A licence can lapse, a domain can move and a brand can be sold; the register is the test of the current state. The customer who runs the search once a year is the customer who is never surprised.

The Honest Closing Word

The honest closing word on existing-customer offers is that the value is in the recurring product, not the headline number. A customer who has worked through a brand’s sign-up is the customer the brand’s Reward Shaker, Acca Booster, Daily Profit Boost and recurring free bets are aimed at, and the brands that run a visible recurring product are the brands the returning customer is best placed to compare. The 10x bonus cap since 19 January 2026 has closed the worst of the gap between the headline number and the cleared bonus, and the £150 vulnerability check has put a softer layer around the customer who is depositing more than they withdraw.

The reader who treats each offer as a four-section document — qualifying bet, bonus balance, wagering requirement, cashout — and who checks the licence on the Commission’s register before opening the account is the reader the Commission’s promotion rules are written for. The reader who reads the headline and stakes the rest of the budget on it is the reader the marketing is written for. Both readers exist, and the rules above are the rules both of them sit inside.

Frequently Asked Questions

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

Since 19 January 2026 the Gambling Commission’s promotion rules cap any wagering requirement attached to a bonus at 10x. A £10 bonus at 50x wagering is no longer permitted; the same £10 bonus at 10x wagering needs £100 of qualifying bets at the operator’s minimum odds, and the small print on the offer page sets the eligible markets and the expiry on the wagering window. Whether the cap applies to a free bet with no wagering condition is not established by the published rules.

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

The minimum odds are the lowest price the bookmaker accepts on a bet that counts towards the wagering requirement — usually 1/2 (1.50), 4/5 (1.80) or 1/1 (2.0). The wagering requirement is the number of times the bonus balance has to be staked before it can be withdrawn, currently capped at 10x. A £10 bonus at 10x on bets at minimum odds of 4/5 needs ten £10 bets to clear the headline turnover, and the operator’s own terms set the eligible markets and the expiry.

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

The free bet is the bookmaker’s stake, not the customer’s, and the standard rule is that the bookmaker keeps the stake when the bet wins. A stake-returned free bet is rarer and is stated in the small print; the customer should check whether the free bet is stake-returned or stake-not-returned before placing the bet, because the two versions of the same headline number return different amounts at the same odds.

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

No. The Commission’s promotion rules in force since 19 January 2026 ban mixed-product promotions — an offer that requires a customer to gamble on two or more product types such as betting, casino, bingo and lottery. “Bet £10 on football to unlock free spins” is the banned shape, and an operator offering it after 19 January 2026 is operating outside the rules. A sports sign-up tied to a casino bonus is not permitted at a licensed UK bookmaker under the current rules.

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

The Commission’s public register is the test. The search accepts a business name, a trading name, a domain or an account number, and the search returns the licence holder, the account number, the licence status and the licensed trading names. The register is free and does not require an account, and a brand that does not appear on the register is not licensed for the Great Britain market. The Commission’s register is the only test, because a licensed operator can run a .com site as easily as a .co.uk one and the domain proves nothing on its own.

Are betting winnings taxed in Great Britain, and who pays General Betting Duty?

Betting winnings are not taxed on the player in Great Britain. General Betting Duty is the bookmaker’s tax on gross profits, currently 15%, with a new remote betting rate of 25% applying from 1 April 2027 within it while remote bets on UK horse racing, pool betting, bets on self-service betting terminals and in-person betting stay at 15%. Until 1 April 2027 the remote rate holds at 15%. Spread betting has its own rates — 3% financial, 10% other — and is a different product. A professional gambler should ask HMRC or an adviser rather than rely on a betting-page summary.
