Existing customer betting offers in Great Britain for 2026
Available in USA welcome bonus is the bait. The recurring offers — free bets that land in your account on a Friday, acca insurances that cushion a near miss, price boosts that top up a market you were already watching — are the hook. For punters who have been with a bookmaker for more than a month, that distinction decides what is actually on offer, and what is just a louder advert for the same thing.
The reason this matters more in 2026 than it used to is a single rule change. Since 19 January 2026 the Gambling Commission has capped wagering requirements on bonuses at 10x. Multi-product promotions — “bet on football to get free casino spins” — are out. Every operator in Great Britain is now working inside the same tight frame, and the comparison between them has moved from headline sums to the small print around them.
Current as of 27 October 2026 against the Gambling Commission’s public register of licensed operators.
What “existing customer offers” actually means
Once the welcome bonus is spent, a bookmaker does not stop trying to keep you betting. The names change but the mechanics are a small family: free bets credited after a qualifying wager, price boosts on selected markets, accumulator insurance that refunds a stake when one leg lets you down, acca boosts that top up winning multiples, loyalty point shops, prize draws. The “existing customer offer” is the umbrella for all of them, and the phrase lands in searches because the welcome bonus is no longer what most regulars are looking at.
Three things separate a recurring offer from a welcome bonus. It does not require a new account, so it is paid for by margin on existing play rather than by customer acquisition. It usually has a shorter shelf life — seven days from credit is common, three days is not unusual for a sport-specific boost. And it is closer to a marketing line item than to a customer contract: bookmakers turn them on and off by event, by sport, by week. A reader who takes the marketing copy at face value is being marketed to. A reader who reads what the offer actually pays, in what circumstances and by when, is comparing.
The comparison this page runs is built on those questions: what triggers the offer, what it pays, when it expires, and what the rules around minimum odds, stake limits and excluded markets take away from the headline number.
The new frame: the 10x wagering cap and what it killed
The Commission’s promotion rules in force since 19 January 2026 reshaped the bonus market more than any rule since the credit card ban in April 2020. Two changes matter here.
Wagering requirements on bonuses are capped at 10x. A £10 bonus used to carry multipliers of 30, 40 or 50; under the cap, no more than £100 of qualifying bets will ever be required to clear it. Read the small print on a £10 “free bet” the same way and you will find that many of them carry no wagering requirement at all — they are winnings-only credits, where you keep the profit but not the stake. Both shapes are legal; both are common.
Mixed-product promotions are banned. Any offer that asks a customer to gamble on two or more product types — “bet £10 on football, get 50 free spins on slots” — is prohibited. The result is that bookmakers can no longer cross-subsidise one product with another, and the £40-in-free-bets sign-up has narrowed into the £20-in-free-bets sign-up at most licensed brands.
The cap does not erase the bonus. It ends the worst of them. A 50x bonus with a £10 face value would have meant £500 of qualifying bets at the operator’s margin; under the cap the same £10 face needs no more than £100. The Commission has not ruled on whether the cap applies to free bets whose stake is not returned — a question that turns on whether those tokens are a “bonus” in the LCCP sense. Bookmakers continue to issue them in the same shape they did before January.
What a free bet is, and what it is worth
The word “free” does the heavy lifting in the marketing copy, and it almost never earns its keep. Two facts settle the real economics.
The stake is not paid back with the winnings. A £10 free bet at odds of 4.0 returns £40 if it wins — the £30 of profit, not the original £10 stake. A £10 cash bet at the same odds returns £50. The £10 is the price of entry; it never comes home.
Minimum odds apply. Most free bets require a minimum price (1/2, 1.5 decimal, evens, 2.0 — pick the operator and check). Below the floor the bet is settled as a normal bet or disqualified altogether, depending on the terms.
The value of a free bet whose stake is not returned can be estimated as a function of its face value, the odds at which it is used and the margin of the market it is spent on. On a typical Premier League match result market, where the margin sits around 5%, a £10 free bet used at 3.0 carries an expected value of roughly £13 to £14. That figure is an average across many bets, not a number a single wager produces. Used at 1.5 it is worth only the £5 of implied profit times one minus the margin, around £4.50.
The same £10 face value is not the same £10 of value across operators. The brand that hands you £10 with no wagering requirement and a 7-day expiry has handed you something different from the brand that hands you £10 of bet credits usable on markets with a 5/1 ceiling. The face value is the marketing line; the conditions determine what you can do with it.
What an accumulator boost really does
An acca boost is presented as a gift: more winnings for the same bet, no extra cost. Three things to know before taking one at face value.
It only applies to winning accumulators. A boost on a 5-fold pays only when all five legs come in. One leg down means the stake is lost in the normal way and the boost is irrelevant. The marketing material does not usually lead with that.
The boost percentage rises with the number of legs. William Hill’s Football Acca Boost, for one, runs from 3% on a double up to 200% on 20 or more selections, with a £10,000 per online bet ceiling and a stated end date of 30 May 2027. The shape is roughly the same across the licensed set: 3% to 5% on a double, climbing toward 100% on a longshot. A punter who plays doubles sees almost nothing; a punter who plays tens sees a lot.
Boosted accas still cost the margin of every leg. Margins compound across selections. A 5-fold where each leg has a 5% margin retains roughly 23% of stake as bookmaker edge before the boost is applied. The boost recovers some of that, never all.
Price boosts and “best odds guaranteed”
A price boost raises the decimal price of a market above the underlying line, by a fixed amount or by a percentage. Best Odds Guaranteed (BOG) is a separate promise on UK and Irish horse racing: if you take the early price and the starting price is bigger, the bookmaker pays the bigger one.
Price boosts usually have a maximum stake. £10 to £100 is common; anything above is settled at the un-boosted price. Read the slip before placing, because the boost often sits invisibly in the bet terms.
BOG is a structural edge for horse racing punters. The bookmaker is offering to pay you the bigger of two prices, so the expected value of an early-price bet is the average of the two distributions rather than the smaller one. BOG does not make the bet positive-EV — the underlying margin is still there — but it narrows the gap and reduces the cost of taking an early price over waiting for the SP. Ladbrokes, Coral and Kalooki all run BOG as a feature.
Acca insurance and refund mechanics
Acca insurance, where a single leg failing returns the stake as a free bet, is a recurring offer across most of the licensed set. Three details always matter.
The refund is usually a free bet, not cash. A £10 acca loses on the final leg; the insurer pays £10 back as a free bet with its own seven-day expiry and its own minimum-odds rule. The “refund” is not a refund in money.
The minimum odds and minimum leg count vary. BoyleSports sets £5 minimum stake, 1/2 minimum combined odds and a £20 maximum refund as a free bet expiring in 7 days, with bets placed and settled on the same day. Other operators copy the shape and tweak the numbers.
BOG and acca insurance stack awkwardly. A bettor who has taken an early price with BOG and is insured on the acca is paying for two protections on the same leg. Read the terms for which one applies if both would, because they often do not both apply.
Welcome bonuses vs recurring offers
The welcome bonus is a different product, even when the headline language looks the same. New customers face a verification gate that returns in seconds at a well-run site and in days at a poorly run one; they receive a one-shot sign-up deal; they are pushed toward an initial deposit match. Existing customers face recurring offers, free bets after a settling wager, acca boosts, loyalty points, prize draws.
The economic difference matters. A welcome bonus funds a new account with the bookmaker’s customer-acquisition budget. A recurring offer funds itself from the existing customer’s margin. That is why welcome bonuses are louder and recurring offers are tighter: the first is marketing, the second is closer to a coupon.
Almost every welcome bonus on this page carries the same shape: deposit and bet £X, receive £Y in free bets. Coral and Unibet both publish “Get £40 in free bets when you bet £20” with a minimum odds line and a 7-day free-bet expiry. Betway matches that with £40 in four £10 tokens after a £10 first bet at minimum 2.0, debit card deposits only and a 7-day expiry. BetUK hands out four £10 free bets (two football accas of 4+ selections and two 2+ multiples) on the same deposit-bet-settle trigger. Sky Bet splits £30 into three £10 tokens after a £5 deposit and a 5p first bet at 1/1 or greater.
The single biggest variable is the qualifying bet’s minimum odds. Coral and Unibet set 2.0 (1/1). BetUK does not specify an odds floor on the welcome offer in its App Store description. Sky Bet sets 1/1. Read it before you place the qualifying bet, because a bet below the floor often means the welcome deal is void.
Reading the small print on a recurring offer
Five clauses in the small print decide what an offer is worth. Skim each before opting in, because most operators do not let you opt out and reclaim a missed credit.
Qualifying trigger. “Place a £10 single bet at minimum odds of 2.0” is a common line; the bet must settle, it must be on a specific market and it must not be cashed out early. Cash-out voids the qualifying bet at most licensed operators, because the bookmaker has taken back its exposure and the trigger no longer makes sense from its side.
Expiry. Free bets typically expire in 7 days. Welcome bonuses expire in 7 to 30 days depending on the operator. A £10 free bet that expires before the weekend’s fixtures is a £10 free bet that paid you nothing.
Minimum odds. A free bet usable only at odds of 4/1 or greater has a narrower real-world menu than one usable at 1/2. On a typical Saturday the 4/1 floor cuts out most of the favourites you would actually want to back.
Maximum payout. The commission cap on a bonus is 10x face. Most bookmakers also apply a stake cap on bonus-eligible wagers and a market cap on acca boosts. Read the bet slip.
Excluded markets. E-sports, novelty markets, virtual sports and certain player-prop categories are routinely excluded from bonus use. The licensed bookmakers are honest about this in their terms; the marketing pages mention it less.
The calculation behind a bonus: wagering, turnover and the cost of clearing
A £10 bonus at 10x wagering needs £100 of qualifying bets to clear. Assuming the punter uses the smallest possible stake to clear the requirement — every bet at £2 — the arithmetic is 50 bets at a 5% margin on a typical market, for an expected cost of £5. The face value is £10; the cost of clearing is £5; the net value is roughly £5, before any price-movement loss on the 50 qualifying bets.
At 50x, the pre-2026 market standard, the same £10 bonus would have required £500 of qualifying bets and 250 bets at £2 — an expected cost of £25 against a £10 face value. The bonus was a loss for most customers before the cap, and the licensed set was issuing them anyway because they were the way to acquire new depositors. The 10x rule ends that race. A bonus issued under the cap is, on average, a small gain for the punter who clears it without error.
The arithmetic on a typical recurring offer is milder. Free bets whose stake is not returned do not require clearing — they are settled as one bet, with the profit paid in cash. The expected value calculation is the simpler one: face value × (decimal odds − 1) ÷ decimal odds × (1 − market margin). On a 5% market with a £10 free bet used at 3.0, that is roughly £10 × 2/3 × 0.95, just under £6.30.
The Top 10 reviewed bookmakers
The ten brands below are reviewed against the same set of fields: who holds the Gambling Commission licence, what the welcome offer is in the operator’s own words, what features the platform runs as recurring offers, and where the comparison turns on a single, named condition. No brand is “the only” licensed one — the Commission’s public register holds many more — and a place on this list is not a licence.
| Brand | Licence holder (account number) | Key recurring offer |
|---|---|---|
| BetUK | LeoVegas Gaming PLC (39198) | Four £10 free bets |
| Copybet | Copybet UK Limited (53774) | Acca Booster and Daily Profit Boost |
| Ladbrokes | LC International Limited (54743) | Odds boosts and Acca Boosts |
| Bet600 | Tyche Tech Limited (44731) | Qualifying-bet welcome offer |
| Bet Ahoy | Bet Ahoy Ltd (100094) | Split-token welcome offer |
| Betway | Betway Limited (39372) | Four £10 free bet tokens |
| Fitzwilliam Sports | SBKI Limited (48760) | High Stakes Welcome |
| BetGoodwin | Goodwin Racing Limited (2927) | Sub-Cover horse racing offer |
| LiveScore Bet | LiveScore Betting and Gaming (Gibraltar) Limited (56859) | Broad payment methods |
| Kalooki Sportsbook | Kalooki Sportsbook Limited (57730) | BOG and daily boosts |
BetUK — debit-card friendly welcome
Licence holder LeoVegas Gaming PLC carries Gambling Commission account 39198, a remote general betting standard (real events) licence, with the platform at BetUK. The sports welcome for new customers: deposit £10 or more and place a sports bet within 7 days of registering to receive four £10 free bets — two football accumulators of 4+ selections and two multiples of 2+. The free bets are valid for 7 days; opt-in is required. Recurring offers on the platform include free-to-play games and acca-style promotions across football.
BetUK suits a customer who wants a clear four-token welcome and is comfortable with a debit card at sign-up. The 4+ and 2+ leg split on the free bets is more restrictive than a flat free-bet token — the four tokens cannot be combined into one £40 free bet, so a customer backing a single outright market cannot use the welcome at full value.
Copybet — acca mechanics front and centre
Licence holder Copybet UK Limited, Gambling Commission account 53774, remote general betting standard (real events). The platform’s headline recurring offer is the Acca Booster — a cash bonus of up to 100% on accumulators of 3 or more selections — alongside a Daily Profit Boost of up to 15%. Welcome offers are published in-app under the platform’s own terms.
Copybet is built for the accumulator customer. The 100% acca booster is among the most generous recurring offers at any licensed brand, paid in cash rather than free bets, and the daily profit boost stacks on top. The draw is a thin welcome structure compared with Coral or Betway; the case for choosing Copybet is the recurring value for a regular acca player, not the new-customer headline.
Ladbrokes — the established feature set
Licence holder LC International Limited, Gambling Commission account 54743, remote general betting standard (real events) and remote betting intermediary. The platform runs odds boosts on horse and greyhound bets, Best Odds Guaranteed on UK and Irish horse races, in-play betting and Acca Boosts. A welcome offer is published on the site; recurring offers include the odds boosts named above.
Ladbrokes is the closest thing to a full-service British bookmaker in this comparison. BOG on horse racing, an in-play product, an acca boost ladder, plus the operator’s familiarity after decades on the high street. For a customer who wants one account and rarely bothers shopping around, the recurring value is hard to beat — but the platform is broader than the niche, so a customer who only bets football or only bets accas could find sharper recurring value elsewhere.
Bet600 — qualification-heavy welcome
Licence holder Tyche Tech Limited, Gambling Commission account 44731, remote general betting standard (real events). The app’s welcome offer requires at least 5 qualifying single bets of £10 or more at minimum odds of Evens (2.0) within the first 7 days of registration. After the fifth settles, one £10 free bet is credited.
Bet600’s welcome rewards a betting pattern, not a single transaction. A customer who would have bet five singles anyway is being paid a £10 free bet for behaviour they were already doing; a customer who would have placed one large bet is not. The trade is straightforward and worth taking for any customer who routinely backs singles at evens or longer.
Bet Ahoy — minimum-trigger welcome
Licence holder Bet Ahoy Ltd, Gambling Commission account 100094, remote general betting standard (real events). The welcome offer is “Bet £10 & Get £10 in Free Bets”, split into a £5 sports bet token and a £5 acca token.
Bet Ahoy keeps the welcome small. The single-digit token amounts are a lower expected value than Coral or Betway at the same qualifying bet, and the split between a sports token and an acca token locks half of the welcome into a specific bet type. The platform suits a customer who already plays accas and wants a low-friction trigger; a flat-token customer gets less.
Betway — the £40 cash-bonus alternative
Licence holder Betway Limited, Gambling Commission account 39372, remote general betting standard (real events). The welcome offer for new UK and Ireland customers 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. Free bets expire in 7 days; debit card deposits only.
Betway’s £40 face matches the higher end of the licensed set, but the debit-card-only deposit rule cuts out customers who bank with Revolut, PayPal or bank transfer. The minimum odds of 2.0 on the qualifying bet is the same as Coral and Unibet, so the comparison comes down to payment-method match and token usability.
Fitzwilliam Sports — the closed-membership tier
Licence holder SBKI Limited, Gambling Commission account 48760, remote general betting standard (real events). Fitzwilliam Sports describes itself as a Dublin bookmaker with capped membership and a “High Stakes Welcome” subject to compliance criteria. Standard welcome offers are not the platform’s product.
Fitzwilliam sits outside the comparison for most readers. The High Stakes Welcome is gated behind compliance criteria that are not published on the home page, and the capped membership model means new accounts are by invitation. A customer who is already a member will know what the recurring value looks like; a customer who is not will not find one in this comparison.
BetGoodwin — three-token welcome
Licence holder Goodwin Racing Limited, Gambling Commission account 2927, remote general betting standard (real events). The platform’s welcome offer is “Bet £10 & Get £15 in Free Bets”, split into a £5 sports bet, a £5 acca and a £5 Sub-Cover bet.
BetGoodwin’s welcome rewards three different bet types at once. Sub-Cover is a horse racing-specific product where the bet covers a non-runner scenario; the £5 token is unusable elsewhere. For a customer who plays the three markets, the £15 is genuinely £15 of value. For a customer who plays football singles, two-thirds of the welcome is unusable.
LiveScore Bet — payment breadth
Licence holder LiveScore Betting and Gaming (Gibraltar) Limited, Gambling Commission account 56859, remote general betting standard (real events). LiveScore Bet accepts debit cards (Visa and Mastercard), Apple Pay, PayPal, Pay by Bank (Open Banking) and Revolut Pay, which is a broader payment set than several of the competitors reviewed here.
LiveScore Bet is the payment-friendly option in the comparison. The breadth of e-wallets and Pay by Bank through Open Banking is unusual among licensed platforms and matters for customers whose bank blocks gambling transactions or whose debit card is overseas. The trade is a thinner welcome headline than Coral or Betway, which makes it the second account rather than the primary one for most readers.
Kalooki Sportsbook — instant withdrawals and BOG
Licence holder Kalooki Sportsbook Limited (company number 12938274), Gambling Commission account 57730, remote general betting standard (real events). The platform 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. Kalooki is a GAMSTOP member.
Kalooki’s case is the speed of withdrawals and the horse racing package. “Within minutes” on a bank transfer is the kind of claim that usually reads as marketing copy; the platform is licensed and the public register backstops it, but the proof is in the customer’s first cash-out. For horse racing punters with BOG and extra-place races on top, the recurring value competes with Ladbrokes and Coral — and for a customer who lives by withdrawals under an hour, the comparison flips on that single feature.
Where the licensed set keeps the same terms
Six terms appear on almost every welcome offer and most recurring promotions. A punter who knows them by heart compares offers in minutes; a punter who reads the marketing copy first will read the terms three times.
Minimum deposit. £5 to £10 is the standard; a few operators offer no-deposit free bets, more common as a recurring promotion than a welcome.
Minimum odds. 1/2 (1.5) to 2.0 is the band on qualifying bets; the odds floor on free bet stakes is usually lower. The higher the floor, the fewer qualifying markets exist.
Expiry. 7 days from credit is the rule of thumb for free bets. Welcome bonus qualifying periods of 14 to 30 days are common. An offer expiring before the next weekend’s fixtures is worthless in practice.
Stake cap. The maximum stake on a bonus-eligible bet is often set at a level that removes any “clear the bonus with one bet” strategy. A £50 cap is common on a £10 bonus.
Excluded payment methods. Skrill, Neteller and some prepaid cards are routinely excluded from welcome bonuses; the offer is void if the deposit uses one. Debit card restrictions (as at Betway) are rarer but apply.
Excluded markets. E-sports, virtual sports and certain player-prop markets are routinely excluded from bonus and free bet use. The list is in the terms, not the marketing copy.
The legality frame around the offers
A bonus issued by a GB-licensed bookmaker runs on three layers of law. The Gambling Act 2005 licenses the operator. The Licence Conditions and Codes of Practice (LCCP) regulate how the operator treats customers. The Commission’s promotion rules since 19 January 2026 cap the bonus itself. All three apply to every brand reviewed in this comparison.
The Gambling Act and the licence register
Every brand on the comparison above holds a remote general betting standard (real events) licence from the Gambling Commission. The register can be searched by business name, trading name, domain or account number; the access date is what makes a licence check honest, because licences can be surrendered, suspended or have conditions added. A licensed brand is bound by the LCCP, the Commission’s social responsibility code and the Remote Technical Standards. An unlicensed brand is not.
Since 7 May 2019 every licensed brand has verified the customer’s name, address and date of birth before the first deposit. That includes deposits made purely to claim a free bet. Anonymous play at a licensed site is no longer possible, and the verification gate is what funds safer-gambling features like the financial vulnerability check.
A GB licence is the only licence that licences an operator whose remote facilities are used in Great Britain. A Curaçao, Maltese or Gibraltar licence does not authorise the operator to take bets from a customer in England, Scotland or Wales — even if the operator is registered in one of those places for other purposes. A brand licensed in Malta and advertising to a British customer is offering an unlicensed product to that customer.
What advertising rules add
The Commission does not licence advertising; the ASA does, through the CAP Code (non-broadcast) and BCAP Code (broadcast). CAP Code section 16 says gambling marketing must be socially responsible, must not be of strong appeal to under-18s, and may not feature anyone who is or seems to be under 25 gambling — that rule is about who appears in the advert, not who may bet.
Since 19 January 2026 the Commission’s promotion rules have applied directly. Two levers matter. Bonuses cannot carry a wagering requirement above 10x. Mixed-product promotions that ask a customer to bet on more than one product type are banned. The Commission has not decided whether the wagering cap applies to free bets whose stake is not returned; bookmakers continue to issue them in the same form.
Since 1 August 2019 no gambling advertisement is shown on TV from five minutes before a live sporting event to five minutes after it before the 9pm watershed. Horse and greyhound racing are exempt. The Premier League clubs’ voluntary withdrawal of gambling sponsorship from shirt fronts (from the 2026/27 season; sleeves and hoardings remain) is not a law — it is a private decision.
Operators are responsible for affiliate marketing under their licence. An affiliate ad that breaks the CAP Code or the LCCP is treated as the operator’s ad. A punter who clicks an affiliate link and finds a misleading bonus headline has the same complaint route as one who clicked the operator’s own page.
Tax: what the punter pays and what the bookmaker pays
Betting winnings in Great Britain are not taxed at the player end. General Betting Duty is the operator’s tax — currently 15% on gross profits — and from 1 April 2027 the remote betting rate within it rises to 25%, while remote bets on UK horse racing and other categories remain at 15%. Until 1 April 2027 the remote rate is unchanged; whether operators pass the duty on through tighter odds is not established by the inputs to this page.
Spread betting carries its own rates — 3% financial, 10% other — and is regulated for its financial products by the Financial Conduct Authority. Spreadex, which runs both fixed-odds and spread betting, states that spread betting losses can exceed the deposit; that is the position under FCA rules, not a marketing line.
The Commission’s statutory levy is a separate charge on operators, not a tax on punters. It is mentioned only to distinguish it from duty, because the press sometimes does not.
What “unlicensed” actually costs the customer
A brand without a GB licence cannot lawfully offer its product to a customer in England, Scotland or Wales. It still does. A customer who uses one is not committing an offence under the Gambling Act, but they give up every protection a GB licence provides: no GAMSTOP coverage, no Commission complaints route, no approved dispute resolution, no British consumer redress if funds are withheld. The 10x bonus cap and the £150 financial vulnerability check do not apply. Identity verification before the first deposit is the operator’s choice, not a legal requirement.
Enforcement is upstream of the customer. The Commission issues cease-and-desist notices, works with search engines and payment providers, and has been given, or is about to receive, court-order DNS blocking powers. None of that makes an unlicensed site illegal to visit; it makes it harder to find and harder to fund.
The honest framing is two-sided. A GB-licensed site verifies identity before the first bet, applies the 10x cap, blocks credit cards and contributes to GAMSTOP; an unlicensed site does not, and offers no British recourse if funds are held. Neither is “the safe choice” by default.
Responsible gambling around offers
A bonus is a marketing line item. A safer-gambling framework is the part of a licensed bookmaker’s offer that protects the customer who would otherwise be marketed into a loss.
GAMSTOP and self-exclusion
GAMSTOP is the national multi-operator self-exclusion scheme, mandatory for online operators since 31 March 2020. A customer can exclude themselves for six months, one year, five years, or five years with auto-renewal. After the minimum period the exclusion stays in place for another seven years unless the customer asks GAMSTOP to remove it. Every operator reviewed in this page is a GAMSTOP member, and the register covers online sites and apps; betting shops use a separate service.
Self-exclusion does not freeze a balance. A customer with funds in their account at the point of exclusion can withdraw them, but cannot deposit, gamble or claim promotional offers during the exclusion period. The point of GAMSTOP is to remove the marketing and the trigger; the rest is the customer’s responsibility.
Safer-gambling tools and the vulnerability check
The LCCP requires every licensed remote betting operator to offer deposit limits, loss limits and wagering limits as configurable safer-gambling tools. DAZN Bet publishes those three on its help pages; the rest of the licensed set offers the same in their account settings. A punter who sets a £100 weekly deposit limit has set a £100 weekly deposit limit; the operator cannot override it without the customer’s consent, and the consent is reversible.
The financial vulnerability check (LCCP condition 3.4.4, in force since 30 August 2024) applies when a customer’s deposits minus withdrawals exceed £150 in a rolling 30 days — a threshold in force since 28 February 2025. The check looks at public records (bankruptcy, county court judgments) for evidence that the customer is in financial difficulty. It is not an income check and not a credit reference check. A punter who trips the threshold is asked questions; an operator who fails to run the check at the threshold is in breach of its licence.
A separate set of “financial risk assessments” — the affordability checks in the press — was announced in a Commission article of 7 July 2026, staged, with no start date. The check, when it lands, will be a deeper look at affordability, not the public-record vulnerability check. Until the start date is published, the live rule is the £150 vulnerability check.
Where to find help
GamCare runs the National Gambling Helpline and provides counselling for problem gambling in Great Britain. GambleAware funds treatment and research through a voluntary industry levy. The NHS runs regional gambling clinics for severe cases. Gamblers Anonymous runs peer-support meetings across the country.
A bonus or a free bet is not a marker of harm. A punter who finds that one of these offers has become the reason they opened the account, or the reason they top it up, or the reason they took a second withdrawal to fund a deposit, has crossed a line that the marketing copy will not admit. The help lines are free, confidential and not connected to any operator.
What to compare before claiming
Five questions frame a real comparison. The marketing line answers none of them, and the terms page answers most of them.
What triggers the offer. A £10 qualifying bet at 2.0 is not the same trigger as five £10 singles at evens. Read the qualifying conditions, count the bets you would have placed anyway, then decide whether the offer is paying you for behaviour you were already doing.
What the offer actually pays. A £40 free bet with a 7-day expiry and a 4/1 minimum odds is not the same as a £40 cash bonus with a 10x wagering requirement. The face values match; the economics do not.
What the minimum odds do. A 2.0 floor cuts out most favourites on a Saturday’s racing card. A 1.5 floor cuts out favourites on most football matches. The floor is the difference between a usable free bet and a stranded one.
What the expiry costs. A 7-day expiry is a deadline the punter has to remember. The bookmaker does not remind; the credit does not roll over. A £10 free bet that expires at 23:59 on a Sunday is a £10 free bet on a Wednesday’s fixtures.
What the limits are. Stake caps, market exclusions, payment-method exclusions and acca-leg caps each shape the offer in a different direction. Read them once, save the terms page, and the second offer is faster to compare than the first.
The arithmetic on Coral’s welcome offer, worked
Coral’s “Get £40 in Free Bets when you bet £20” is the most-cited welcome in the comparison, so it earns the worked example. The qualifying bet is £20 at minimum odds of 2.0, paid by debit card or instant bank transfer; £40 in free bets is credited within 7 days; free bets expire 7 days after issue. Stake not returned with winnings.
A punter who would have placed the £20 bet anyway has spent no qualifying stake. The free bets are pure upside. Assume the punter uses the £40 across two selections on football match result markets at decimal odds of 3.0 and a market margin of 5%.
Expected value of the first £20 free bet at 3.0: £20 × (3.0 − 1) ÷ 3.0 × (1 − 0.05). £20 × 0.6667 × 0.95 = £12.67. Same calculation on the second £20 free bet at 3.0: another £12.67. Combined expected value across the £40 face: £25.33.
That is the expected gain across many such uses, not the result of any single claim. A punter who uses the free bets at 1.5 instead of 3.0 sees the value collapse: £20 × 0.333 × 0.95 = £6.33 per £20 free bet, £12.67 across the £40. The minimum odds rule applies to the qualifying bet, not to the free bets themselves in Coral’s published terms — but the higher the price you take, the higher the expected value of the welcome.
The same arithmetic holds for Unibet, which publishes an identical face value and trigger. Betway’s £40 face has the same expected value if used at the same odds and on the same margin — the difference is the debit-card-only deposit and the four-token split.
The brands that almost made the comparison
Four brands sit close to the line and are worth naming, with the reason they did not displace a reviewed bookmaker. Coral, Unibet, BetVictor, William Hill, bet365, Sky Bet, BoyleSports, Spreadex, Kwiff, Smarkets/SBK, Star Sports, DAZN Bet, QuinnBet — all carry Gambling Commission licences and publish welcome and recurring offers in the same shape as the ten reviewed above. Coral and Unibet both publish the “£40 in free bets” welcome; bet365 and William Hill carry deep feature sets with Bet Builder+, Super Boosts and acca ladders; BoyleSports publishes a published acca insurance and an acca loyalty promotion with named minimums; Kwiff runs a Supercharge feature that instantly boosts odds on a bet, for example from 2/1 to 20/1; QuinnBet publishes free-bet terms with named minimum odds and named maximum odds; Smarkets/SBK publishes a different welcome shape entirely. The comparison on this page is the ten reviewed above; the wider licensed set is materially larger and the Commission’s public register is the index.
Frequently asked questions
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 needed £500 of qualifying bets before the cap; under the rule no more than £100 of qualifying bets can be required. The cap does not apply to free bets whose stake is not returned, by the Commission’s published position.
What do minimum odds and the wagering requirement mean in a sign-up offer?
Minimum odds are the floor on the qualifying bet — typically 1/2, 1.5 or 2.0. Bets below the floor usually do not qualify. The wagering requirement is how many times the bonus (or bonus plus deposit) must be bet before winnings become withdrawable; in Great Britain it cannot exceed 10x the bonus since 19 January 2026.
Why is the stake of a free bet not paid back with the winnings?
A free bet whose stake is not returned settles as profit only. A £10 free bet at 3.0 returns £30, not £40, because the original £10 does not come back. Some bookmakers offer free bets whose stake is returned (“bet credits” or “cash bonuses”) — those are different products, with their own terms.
Can a bet on sport be tied to a casino bonus under the Commission’s promotion rules?
No. Mixed-product promotions — those requiring gambling on two or more product types, such as betting plus casino, or bingo plus lottery — have been banned since 19 January 2026. An offer of “bet £10 on football, get 50 free spins” can no longer be marketed by a GB-licensed operator.
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. Every brand reviewed on this page carries an account number and a licence-holder name in the register. Always check the access date — licences can be surrendered, suspended or have conditions added.
Are betting winnings taxed in Great Britain, and who pays General Betting Duty?
Betting winnings are not taxed at the player end in Great Britain. General Betting Duty is the operator’s tax on gross profits, currently 15% (with a remote betting rate of 25% from 1 April 2027 on most online bets, while UK horse racing and certain other categories remain at 15%). The duty is the operator’s liability, not the punter’s.
