The welcome offer is the bit everyone sees. The recurring promotions are the ones a bettor actually lives with for months and years afterwards, and they rarely get the same scrutiny. This page ranks ten Gambling Commission-licensed bookmakers on what they hand back to customers who have already signed up, using only the terms each operator publishes. Nothing here is a tip; nothing here tells a reader who will win. The job is to lay out the recurring offers, their conditions, and what they cost a punter who clears them.

Where the loyalty offers sit inside UK law

The headline that bounds this whole market is the Gambling Commission’s package of promotion rules that came into force on 19 January 2026. Two restrictions matter to a regular punter browsing this page.

First, any wagering requirement attached to a bonus is capped at 25 times the bonus value. A £10 bonus that asked for 50 times play would mean £500 of qualifying bets; under the new ceiling no bonus can demand more than £250 of turnover for every £10 issued. That ceiling applies to deposit-match bonuses, free bet clubs that credit bonus money subject to play-through, and similar mechanics. Whether it bites into a free bet that carries no wagering condition at all is not established by the Commission’s published guidance, which is why this page treats stake-not-returned free bets as a separate mechanism rather than folding them into the bonus calculation.

Second, mixed-product promotions are banned. The “bet £10 on football to unlock 50 free spins” pattern that was once routine across UK-licensed sites is no longer permitted, because it forces a customer to gamble on two or more product types (here betting and casino) under one offer. Existing customer mechanics that stay alive — acca boosts, acca insurance, price boosts, free bet clubs paid in stake-not-returned tokens, loyalty point schemes — tend to be single-product by design. That is no accident: it is the shape that fits the rule.

The 25x ceiling is the upper bound on the worst deal still legal; it is not a recommendation. Plenty of licensed bonuses carry a much lighter 1x or 5x turnover, and several recurring promotions carry no wagering requirement at all because they pay cash, not bonus credit. The point of the cap is that no bookmaker licensed in Great Britain can demand the eye-watering 40x or 50x rollovers that are still routine on casino offers in other jurisdictions.

Outside the bonus rules, the wider legal frame is the Gambling Act 2005. The Commission licenses every operator taking remote bets from customers in Great Britain, whether the operator itself is based in London, Gibraltar, Malta or anywhere else — that is the point of the 2014 Act, which made the point of consumption, not the point of incorporation, the test. The Commission’s public register is the only place a licence can be verified, and the search works by business name, trading name, domain or account number. Every operator reviewed below appears on that register against a current remote betting licence.

Two duties belong to the customer, not the operator. Identity verification is mandatory before the first deposit, including for free bets and bonuses; name, address and date of birth are checked before a penny goes through. And since 14 April 2020 no credit card can be used for gambling in Great Britain, including credit-card-funded e-wallet top-ups. Debit cards, instant bank transfer, and bank-based rails such as Trustly and TrueLayer remain standard at the operators reviewed here.

Safer gambling: what every offer inherits

Every promotion reviewed on this page runs inside the safer-gambling perimeter that a Commission licence requires. Three things follow for a punter browsing these offers.

GAMSTOP is the national online self-exclusion scheme, mandatory for every GB-licensed operator since 31 March 2020. Self-exclusion can run for six months, one year, five years, or five years with auto-renewal; after the minimum period a further seven-year hold applies unless the customer asks GAMSTOP to lift it. An offer presented to a customer who has self-excluded is not delivered: the operator is bound to check. GAMSTOP covers online sites and apps; betting shops run a different offline service.

Financial vulnerability checks are another licence condition. Since 28 February 2025 a licensed remote operator runs a public-record check on any customer whose net deposits (deposits minus withdrawals) exceed £500 in a rolling 30 days — looking at indicators such as bankruptcy orders or county court judgments. It is not a credit reference check and not an income check. The wider “affordability checks” the press often discusses — properly called financial risk assessments — were announced in a staged plan on 7 July 2026 with no confirmed start date; this page treats them as announced, not as live.

Deposit limits belong to the customer. A licensed site must offer a gross deposit limit on a fixed time frame (the RTS 12 deposit-limit framework); the first changes applied on 31 October 2025, with a second phase postponed to 30 September 2026. There is no state-set ceiling on deposits or losses: the cap is whatever the customer chooses. Every brand reviewed below lets the punter set their own deposit ceiling, daily or weekly, in their account settings.

For help, GamCare runs the National Gambling Helpline, GambleAware funds treatment and the NHS gambling clinics treat problem gambling as a health condition. Gamblers Anonymous runs peer-support meetings. None of these is a substitute for a self-exclusion if the promotions on this page are starting to do more harm than good.

How a recurring offer is judged here

The plan behind the ranking rests on what a promotion actually costs a punter to clear, not on the headline amount.

The mechanics worth knowing

A wagering requirement is the multiplier on a bonus that must be turned into qualifying bets before any winnings become withdrawable. A £10 bonus with a 30x requirement means £300 of qualifying bets; the same £10 with no wagering condition pays out as cash the moment a winning bet settles.

Minimum odds are the floor below which a bet does not count toward clearing a bonus. A “min odds 2.0” requirement means singles or legs at 1/1 or longer in fractional form. Accumulators clear the floor more easily, but a minimum-legs clause often comes attached.

An expiry window is the time a bonus or free bet must be used within. Seven days is the most common window for free bets; deposit-match bonuses tend to run for 30 days. A free bet that expires is a free bet that disappears, and the stake is rarely returned with any winnings — which is why a £30 free bet at odds of 5.0 wins £120, not £150.

Price boosts and acca boosts are token increments on the odds of a named market. They are paid as extra winnings on top of the standard return, not as bonus credit, so they tend to carry no wagering condition.

Acca insurance refunds a stake as a free bet (not cash) if one leg of an accumulator lets the punter down. The maximum refund is small — £10 to £20 is typical — and the free bet refund usually carries its own expiry.

Cash out lets a punter settle a bet before the event finishes, locking in a return that the bookmaker quotes in real time. It is not a promotion; it is a feature. But it interacts with offers, because many operators exclude cashed-out bets from bonus qualification.

The arithmetic behind a typical bonus

The 25x cap means the calculation has a ceiling. Take a £10 bonus with the maximum legal 25x wagering requirement: the punter must place £250 of qualifying bets. At a minimum stake of £5 per qualifying bet, that is 50 bets. At odds of 2.0 (1/1 fractional) or longer, and assuming the punter picks markets at a margin of around 5%, the expected cost of clearing the bonus is £250 multiplied by the 5% margin: roughly £12.50 of expected loss against a £10 bonus.

That is the band the rest of this page sits inside. The bonus is rarely worth more than its face value once the margin of the markets used to clear it is counted in; the worst legal deals sit close to break-even; the best ones pay a small surplus over the clearing cost. None of this is a tip on which market to pick; the margin is a property of the bookmaker’s price, and that is what this calculation measures.

The ten bookmakers reviewed

The brands below appear in the order set for this page, not by some abstract quality score. Each carries its own licence number from the Commission’s public register, and the headline on each write-up names the thing that sets it apart inside this comparison.

BetTom — bonus plus slot bundle

BetTom’s licence is Commission account 64959, held by Bet Tom Limited; the licence covers remote general betting standard (real events). The site’s headline for new customers is a 50% back offer of up to £50 as a free bet, paired with a matching 50% back up to £50 as free slot funds for casino play. That paired structure is the most legally exposed of any reviewed here: it sits on the mixed-product boundary the Commission has banned since 19 January 2026, and any continuing version of it for new customers would need to be reworked into two distinct offers. Existing customers at BetTom are typically reached through ongoing price boosts and event-specific promotions rather than a published loyalty scheme.

For a punter comparing brands, BetTom’s value depends on whether the matched offers are still split cleanly into a sports-bet-only bonus and a casino-only bonus. If they are, the sports element is a straightforward 50% back. If the two are still linked, the offer has no place on a GB-licensed platform under the new rules.

Coral — daily free games plus acca boosts

Coral’s licence is Commission account 54743, held by LC International Limited; the licence covers both remote general betting standard (real events) and remote betting intermediary. Coral runs a daily Reward Shaker — a free-to-play prize mechanic — alongside an Odds Booster on hundreds of markets, free-to-play games including Football Super Series with a £10,000 jackpot, and the standard acca insurance pattern.

Coral’s welcome offer for new GB customers is “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 seven days and expiring seven days after issue. Qualification requires a debit card or instant bank transfer; the site’s listed payment methods include Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly.

For the existing customer, the Reward Shaker is the daily mechanic worth knowing about. It is genuinely free to enter, costs nothing to play, and pays small prizes in free bet tokens. It does not replace a price boost or an acca boost, but it stacks alongside them — and unlike a bonus it carries no wagering requirement, because the entry itself is free.

Dabble — social feed plus straight free bet

Dabble Sports UK Ltd holds Gambling Commission account 65677, licensed for remote general betting on real events. The brand’s signature is a social feed attached to the betting slip — customers can follow tipsters, copy their bets, and chat around selections. The welcome offer for new customers is “Bet £10, Get £10 in Free Bets” on a first deposit, with minimum odds applying, a seven-day free bet expiry and the stake not returned with any winnings.

The stake-not-returned detail is what matters for arithmetic. A £10 free bet at odds of 5.0 returns £40 — £50 in winnings minus the £10 stake the bookmaker keeps. The free bet is worth its face value only if the punter finds an overpriced selection; at the margin the bookmaker applies to a typical market, the value comes out close to half the face value over many bets.

For the existing customer the social feed is the promotion. Following a tipster who posts a steady stream of selections is, in effect, a free research feed, and the brand layers standard acca insurance and price boosts on top.

Sky Bet — free bet club plus Super Boosts

Sky Bet holds Gambling Commission account 67370, under SBG Sports Limited, for remote general betting on real events. The welcome offer for new customers is £30 in free bets, credited as three £10 free bet tokens after a deposit of at least £5 and a first single or each-way bet of at least 5p at odds of 1/1 or greater. The 5p minimum stake is a Sky Bet quirk: it lets a customer qualify for £30 of free bets for a five-pence first bet, but the qualifying bet must still settle before the free bets are issued.

For existing customers the Sky Bet free bet club is the standing offer: stake a set amount during the week and receive a free bet the following week, no wagering requirement because the credit is paid as a free bet rather than bonus money. The brand also runs Super Boosts (enhanced odds on a named daily selection) and regular price boosts across football and horse racing. Sky Bet’s coverage of British and Irish horse racing is wide, and Best Odds Guaranteed is standard.

The free bet club is the recurring mechanic worth pricing. If a punter’s weekly staking reaches the threshold naturally, the free bet is genuinely free; if the punter chases the threshold with marginal bets, the margin on those extra bets is the real cost.

Kalooki Sportsbook — instant withdrawals plus BOG

Kalooki Sportsbook holds Gambling Commission account 57730, licensed to Kalooki Sportsbook Limited for remote general betting on real events. The site is one of the smaller Commission-licensed brands in this comparison, but it makes specific promises to existing customers: 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 differentiator. Many sites describe a withdrawal as “instant” while routing the funds through a queue; Kalooki states the times directly. For a punter who cycles money in and out — backing, laying off, withdrawing — the speed matters more than any free bet.

The BOG promise on UK and Irish racing is the other recurring mechanic: if the starting price is bigger than the price taken, the bet is settled at the SP. That is a guarantee with no wagering cost — the punter gets the better of two prices for free.

Sporting Index — fixed-odds plus spread bundle

Sporting Index’s licence is Commission account 27343, held by Sporting Index Limited, covering remote general betting standard (real events). Sporting Index runs both fixed-odds and spread betting on the same account. The new-customer offer reflects that bundle: 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 or cashed out early.

For the existing customer, Sporting Index’s standing offer is the spread component: regular spread betting price promises and Total Goals Index specials on football. The brand sits outside the fixed-odds mainstream, which is the point. A punter who wants both fixed odds and spread betting on the same wallet finds it here and nowhere else among the ten reviewed.

The commission-bundled nature is also why the offer is split across product types rather than mixed: each token is single-product, which keeps the offer inside the Commission’s mixed-product ban.

Copybet — copy-trading plus acca booster

Copybet UK Limited holds Gambling Commission account 53774, with a remote licence for real-event betting. The brand’s signature mechanic is copy-trading: a customer can copy the bets of a named tipster, with the stake, selection and odds replicated automatically. The Acca Booster pays up to 100% cash bonus on accas of at least three selections; the Daily Profit Boost offers up to 15% extra on named markets.

The Acca Booster is unusually generous by UK-licensed standards. A 100% cash bonus on a winning acca is paid in cash, not free bet tokens, which means no wagering requirement and no stake-not-returned complication. The Daily Profit Boost is paid the same way.

The condition on the Acca Booster is the legs threshold: at three selections the boost is modest; the headline 100% applies at the upper end of the leg count. A punter who usually bets trebles and fours gets the lighter end of the scale; a punter who builds six-folds and longer gets the headline rate.

QuinnBet — acca insurance plus free bet rules

QuinnBet (Gibraltar) Limited operates under Gambling Commission account 61011, which permits remote general betting on real sporting events. The brand’s free bet terms are the most explicit on this page: free bets are valid for seven days from credit, usable on any market at odds of 1/2 (1.5 decimal) or greater, with a maximum odds ceiling of 50/1; straight accumulators are allowed but Trixies, Patents and Yankees are excluded.

The exclusion of combination bets beyond a straight accumulator is the unusual detail. A Patent is seven bets on three selections (three singles, three doubles, one treble); a Trixie is four bets on three selections. Excluding them from free bet use closes off several popular staking patterns, and a punter who plans to use QuinnBet free bets on a Yankee needs to know that the system bet will simply be voided for free bet purposes.

For the existing customer, QuinnBet’s standing offers include acca insurance and event-specific price boosts, plus a free bet club on a weekly staking threshold.

10bet — bonus plus daily free bets

Blue Star Planet Limited, trading as 10bet, is licensed under Gambling Commission account 43173 for remote general betting on real events. The brand’s headline for new UK sign-ups is a 100% bonus up to £50, plus daily free bets and free spins. The 100% bonus up to £50 is at the upper end of the standard deposit-match range; the wagering requirement and minimum odds for clearing it sit inside 10bet’s customer terms.

For existing customers, the daily free bet is the standing mechanic — a credited free bet token each day, often tied to a named fixture, with the standard seven-day expiry and stake-not-returned settlement. The free spins component is the casino side and is now, under the 19 January 2026 rules, split cleanly from the sports offer.

A punter who values a daily token over a weekly free bet club will prefer 10bet’s cadence; a punter who would forget to use a daily token before it expires will prefer a weekly club.

Smarkets — exchange plus SBK sportsbook

Smarkets’ licence is Commission account 39173, held by Smarkets (Malta) Limited, covering remote betting intermediary. Smarkets runs a betting exchange (back and lay, peer-to-peer) and, alongside it, the SBK sportsbook. The SBK welcome for new customers is a £20 first deposit and £20 bet at minimum odds of 3.0 for £60 in free bets issued within 48 hours, with Cash Out, Bet Builder and live horse racing streams.

The 3.0 minimum odds on the qualifying bet is the highest of any reviewed here, and it shapes who the offer suits. A punter who would naturally place a first bet at long odds on a football underdog or a horse at a bigger price qualifies cleanly; a punter whose first instinct is a short-odds favourite does not.

For the existing customer, SBK layers standard price boosts and a free bet club onto a sportsbook that sits beside a low-margin exchange. The two parts of the brand share a wallet, which is unusual and useful for a punter who likes to back one side on the exchange and lay on the sportsbook when prices diverge.

How the recurring offers compare

The table below lays the ten brands against the Commission’s licence record and the existing-customer offer pattern each one runs. The middle two columns are facts from the Commission’s public register; the rightmost column is a brief description of what the operator’s own terms say on the recurring promotion at the heart of this page.

Three patterns stand out across the ten brands. First, the weekly free bet club is the most common standing offer: Sky Bet, QuinnBet and 10bet all run one, with Coral’s daily Reward Shaker as the closest variant. Second, price boosts and acca boosts are universal — every brand reviewed runs them in some form, and they pay extra winnings on top of the standard return rather than bonus credit. Third, several brands run distinct mechanics that no competitor offers: Copybet’s copy-trading and cash-paid Acca Booster, Sporting Index’s spread bundle, Kalooki’s instant withdrawals, Smarkets’ exchange-plus-sportsbook wallet. Those distinct mechanics are the reason a punter compares brands in the first place.

Reading the existing customer offers properly

A promotion that costs £10 of expected loss to clear a £20 bonus is, on average, a £10 win for the punter; if that cost increases to £50, the result is an average £30 loss. The arithmetic is dull and the conclusion is unflattering to the marketing.

The honest ranking is this. Acca boosts paid in cash (Copybet’s Acca Booster, the Daily Profit Boost) sit at the top because they pay extra winnings with no wagering requirement and no stake-not-returned complication. Free bet clubs with a low staking threshold and a seven-day expiry sit next, because they reward staking the punter would have done anyway. Best Odds Guaranteed on horse racing (Sky Bet, Kalooki) and instant withdrawals (Kalooki) are the kind of standing mechanic that pays the punter over a year rather than over a single bet. Price boosts are everywhere and rarely worth chasing for their own sake, but the headline boost of the day on a market the punter would have bet anyway is a small free addition. Welcome bonuses with 25x wagering are the worst deals still legal under the new cap; at £10 of bonus with £250 of clearing turnover and a 5% market margin, the expected cost is around £12.50 against £10 of bonus, leaving the punter slightly out of pocket.

The 19 January 2026 cap is the ceiling on the worst. The ceiling does not turn bad bonuses into good ones; it just stops the worst of them. A punter who clears a 25x bonus on markets with the lowest available margin at this bookmaker is still paying through the margin, and the £10 face value of the bonus is the upper bound on what is realistically being given away.

The fundamentals in one paragraph

The recurring promotions at the ten GB-licensed bookmakers reviewed here are bounded by the Commission’s promotion rules: 25x maximum wagering on bonuses, no mixed-product offers, mandatory GAMSTOP, mandatory identity verification before the first deposit. Inside those bounds, the offers divide into cash-paid boosts (the cheapest to the punter), free bet clubs (cheap if the staking threshold is met by bets the punter would have placed anyway), stake-not-returned free bets (face value minus the margin), and deposit-match bonuses with wagering (the most expensive to clear). The Commission licence is the floor: every brand here holds one. The choice among them turns on which recurring mechanic best matches the punter’s existing pattern of staking.

Frequently asked questions

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

The Gambling Commission’s promotion rules, in force since 19 January 2026, cap wagering requirements on bonuses at 25 times the bonus amount. A £10 bonus at 25x turnover means £250 of qualifying bets; a £50 bonus at the same cap means £1,250. Whether the cap applies to a free bet with no wagering condition is not established.

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

The wagering requirement is the multiple of the bonus that must be turned into qualifying bets before winnings become withdrawable. Minimum odds are the price floor below which a bet does not count toward that turnover — a “min odds 2.0” rule in fractional form is 1/1 or longer. A bonus with a low minimum stake per qualifying bet and a long window is cheaper to clear than one with a high stake or a short window.

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

A free bet is paid in tokens, not cash; the bookmaker keeps the stake whether the bet wins or loses, and only the winnings above the stake are returned. A £10 free bet at odds of 5.0 returns £40, not £50. That structure is what makes a free bet worth roughly its face value multiplied by the edge the punter finds, not its face value plus the winnings.

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

No. The 19 January 2026 promotion rules ban mixed-product offers that require a customer to bet on two or more product types such as betting, casino, bingo and lottery under one promotion. A sportsbook bonus that hands out casino free spins as part of the same opt-in is not permitted; the two must be split into separate offers with separate opt-ins.

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

The Commission’s public register is searchable by business name, trading name, domain or account number; the search returns the licence categories, the licence holder’s legal name, and the registered trading names. Every brand reviewed on this page appears on that register against a current remote betting licence. The register is the test; the domain (.com or .co.uk) 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 customer in Great Britain. General Betting Duty is the operator’s tax on gross profits from betting, currently 15%, with a new remote rate of 25% applying from 1 April 2027 for remote bets other than those on UK horse racing; the duty is paid by the operator and not deducted from customer winnings.
