Most “best betting sign up offers 2026” lists print the bonus size, name the bookmaker, and move on. That’s the kind of comparison a marketer writes, not the kind a punter can use. A welcome offer’s headline number is the smallest part of its cost. What the operator really takes from you is the turnover requirement, the minimum price on qualifying bets, the time limit, and the fine print that decides whether your free bet’s stake comes back when you win. Two welcome offers that look identical on the first line can cost you wildly different amounts to clear, and a third can be worth more than both of them precisely because it demands less. This page breaks ten of the licensed operators’ opening deals down to the arithmetic a punter actually cares about, and asks, for each one, who it’s worth it for.

The State of Sign-Up Offers in Great Britain in 2026

A welcome offer is a marketing expense, and a marketing expense has to be earned back from somewhere. The “somewhere” in sports betting is the margin built into every price the bookmaker quotes, plus the terms the customer must satisfy before any of the advertised credit can be withdrawn. For most of the past decade the second of those two mechanisms was the harder one to see, because operators stacked welcome offers with turnover requirements of 30x, 40x, even 50x the bonus amount, attached them to a minimum odds floor of 1/2 or 4/5, and timed the whole thing to expire inside two weeks. A punter who deposited, took the offer, and tried to play through the requirements in a way that beat the margin would arrive at a withdrawal screen having given back, on average, more than the bonus they were paid.

That changed on 19 January 2026. The Commission’s updated social responsibility code now caps the wagering requirement on a sports bonus at 10x the bonus amount, and bans mixed-product promotions outright: no offer can compel a punter to gamble on two or more product types, such as betting and casino, as the price of claiming it. A £10 bonus at the old 50x rate asked for £500 of qualifying turnover. The same £10 bonus under the current rules asks for no more than £100. The cap applies only to bonuses with a wagering condition, and the Commission’s public guidance has not yet settled whether a free bet with no rollover at all falls inside it. The free bets most operators pay out as their welcome incentive are unaffected, in practical terms, by the cap: a free bet that returns only profit, not stake, is a different mechanic, and the value calculation is different too.

The headline change is real and welcome, but it does not turn a sign-up offer into a gift. Three other levers still sit in every operator’s terms: the minimum odds on the qualifying bet (the bet you have to place to unlock the free bets), the expiry window on the free bets once they’re issued, and any cap on what the free bet can return. Two operators on this list use the same “bet £10, get £30 in free bets” formula. They differ sharply in how soon those free bets expire and what they can return when they win. A reader who only sees the front page misses that, and pays for the missing detail in punted-on odds.

Who Regulates Sign-Up Offers in Great Britain

Every bookmaker covered on this page holds a remote operating licence from the Gambling Commission, the non-departmental public body set up under the Gambling Act 2005 to license the British commercial market. The Commission’s register lists the licence categories, the licence holder, the trading name, and the account number a punter can check; it covers England, Scotland and Wales, while Northern Ireland runs its own older regime and is not regulated by the same statute. A British licence is required at the point of consumption: a Curaçao, Malta or Gibraltar licence does not authorise an operator to take bets from customers in Great Britain.

Five remote licence categories are relevant to a sports punter. Remote general betting standard (real events) covers fixed-odds sports books. Remote general betting standard (virtual events) covers computer-generated events. Remote general betting limited is the smaller-scale version. Remote pool betting covers Tote-style wagering. Remote betting intermediary covers the exchanges that match back and lay bets between customers. The operators on this page sit in the first and fifth categories; spread betting that runs on financial instruments is regulated by the Financial Conduct Authority, not the Commission, and the two are different products with different rules.

Before a customer can place their first bet, the operator has to verify their name, address and date of birth, a duty in force since 7 May 2019 and binding on free bet and bonus play, not just paid betting. That check is the reason no GB-licensed site allows anonymous play. A financial vulnerability check, an LCCP requirement since 30 August 2024 and now triggered once a customer’s net deposits cross £150 in a rolling 30 days, runs a public-record search for county court judgments, bankruptcies and the like. It is not a credit check. A further tier of financial risk assessments, the press’s “affordability checks”, was announced in a Commission article on 7 July 2026 and is staged, with no start date. Until the Commission publishes one, write “announced, staged, no start date” rather than “in force”.

Marketing and the 10x Wagering Cap

The bonus cap, the mixed-product ban, and the wider marketing rules in the LCCP run alongside the CAP Code (non-broadcast) and BCAP Code (broadcast) enforced by the ASA. CAP Code section 16 sets the tone: marketing must be socially responsible, must not strongly appeal to under-18s, and must not feature anyone who is or seems to be under 25 in a significant role, with an exception for in-betting-shop placements. The under-25 rule concerns who can appear in the ad, not who is allowed to bet, and conflating the two is a common error. The “whistle-to-whistle” ban on live sport TV advertising, in place since 1 August 2019, is an industry code, not statute, and excludes horse and greyhound racing.

The mixed-product ban does the most work for a punter’s wallet. An offer structured as “place a £10 sports bet to receive 50 free spins” is no longer licensable. Free spins on slots are not a sports betting incentive, and an operator that wants to give them away has to do so without making the customer put a sports bet in. The rule trims a category of cross-sell that previously let a bookmaker use the sportsbook as a funnel for higher-margin casino play. The wagering cap closes the same gap from the other side: it stops an operator from offering a small bonus with a punishingly large turnover requirement attached, which is the structure that did the most damage to inexperienced customers. Neither rule is a full answer, but together they reset what a fair welcome offer is.

How Much a Sign-Up Offer Really Costs

Three numbers decide what a welcome offer is worth. The first is the bonus size, which is just the figure the operator prints. The second is the wagering requirement, the multiple of the bonus the punter must stake before any of the bonus or its winnings becomes withdrawable. The third is the market margin, the share of every pound bet that the bookmaker keeps on average. The first number tells you what the offer looks like. The other two tell you what it costs.

The cost of clearing a bonus is not hard to estimate. Take a £10 sports bonus with a 5x wagering requirement, a minimum qualifying price of 1/2 (1.50 decimal), and a market margin of around 5%, the kind that runs on a mainstream football 1X2 line. The required turnover is £50, the share of that turnover the bookmaker keeps is £2.50, and the punter finishes the rollover having lost, on average, the £2.50 — which the operator recoups from the margin of every bet placed, not from the bonus money. The same £10 bonus under the new 10x cap asks for £100 of turnover and costs, on the same margin, around £5. A 50x bonus that was common before 19 January 2026 asked for £500 and cost, on the same margin, around £25. The cap reduces the expected cost of clearing a bonus by roughly the same factor it reduces the turnover, which is why the rule matters even to punters who never read it.

A free bet with no wagering requirement is a different animal. A £10 free bet at minimum price 1/2 (1.50 decimal) has, on average, about £3.33 of expected value, because the stake is not returned with a win and the operator’s margin takes a slice off the implied price. The figure is an average over many bets: on a single bet, the punter either wins £5 profit or gets nothing. The expected value falls as the minimum price on a free bet is allowed to be lower, and rises as the bookmaker restricts the markets on which the free bet can be used, the same way a casino comp becomes more valuable the narrower the games it can be spent on.

A specific worked example: the Coral sports welcome offer, as Coral’s site states it on 16 October 2026, is “Get £40 in Free Bets when you bet £20”. The qualifying bet is a deposit and a single sports bet of £20 or more at minimum odds of 2.0 (1/1), and the £40 of free bets is issued within 7 days and expires 7 days after issue. The qualifying £20 has to be turned over at the 1/1 minimum once, with no rollover multiplier on the bonus itself. The £40 of free bets, if used on a market with a 5% margin at minimum free-bet price 1/2 (1.50 decimal), has an expected value of roughly £13.30 across the four free bet tokens. The qualifying bet itself, placed at fair odds, costs about £1 on a 5% margin. Net of the qualifying cost, the offer is worth, on average, somewhere in the region of £12 to the punter. That is a real number, not a marketing number, and it is what a careful reader should be looking for.

The 10x Cap in Practice

The cap came into force on 19 January 2026 and applies to wagering requirements on sports bonuses. The Commission’s published examples are clear: a £10 bonus at 50x requires £500 of turnover, and a £10 bonus at 10x requires £100. Above the cap, the offer is not licensable. Free bets whose only requirement is to be used at a minimum price and within an expiry window are not directly addressed in the public guidance, and the operators listed here issue their welcome incentive predominantly as free bets rather than as cash bonuses. A punter comparing two offers should read the small type to see whether the headline is a cash bonus with a turnover requirement or a free bet with an expiry, because the arithmetic on the two is not the same.

What a Bookmaker’s Own Terms Say on a Welcome Offer

The table below pairs each operator’s licence against the headline terms of its own sign-up offer, as those terms are stated on the operator’s site or app on 16 October 2026. The licence column gives the Gambling Commission account number and the licence holder; the offer column gives the headline structure, the minimum odds, the expiry, and any cap the operator’s own terms name. The table is a snapshot, not a recommendation, and each operator’s full terms are the binding document.

A first reading of the table raises a question: why do some operators publish their welcome offer on the home page, and others bury it inside the app? The reason is the Commission’s marketing rules. The LCCP and the CAP Code both require that the headline offer not be presented in a way that obscures the qualifying conditions, and operators that choose to publish a single landing page for the welcome have to balance the offer’s prominence against the conditions’ clarity. Operators that push the offer into the app can show it at sign-up, when the customer is in the flow, and avoid the front page becoming a marketing claim. The trade-off is a worse experience for the punter comparing deals on a desktop, and a better experience for the punter who has already chosen the brand.

The Ten Operators

The ten operators below are the brands listed on the Gambling Commission’s public register against a remote betting licence. They are presented in the order the Commission’s register groups them under their licence holders, not as a ranking. The treatment of each is in three parts: what the licence says, what the offer says, and a verdict on who, if anyone, the offer is for.

LiveScore Bet

LiveScore Bet operates under Commission account 56859, held by LiveScore Betting and Gaming (Gibraltar) Limited. The site accepts debit cards (Visa and Mastercard), Apple Pay, PayPal, Pay by Bank through Open Banking, and Revolut Pay. The app’s home page does not, on the reviewed date, publish a headline welcome offer. The operator’s wider product leans on in-play prices and the live scores feed that the brand has carried since its early days; the welcome side is quieter than most.

A punter who values the in-play product over the welcome offer will find LiveScore Bet a competent place to hold a small account. A punter whose reason for opening a new bookmaker is the welcome offer will have to take the offer’s terms from the app’s sign-up screen rather than the front page, and that is the answer to the question of who the offer is for: a customer who has already decided to use the brand and is happy to read the small type on the way in.

VBet

VBet operates under Commission account 44662, held by SCGO Limited. The headline welcome is a £10 free bet to a new, verified customer who stakes £10 or more on a first bet that loses. The qualifying bet is the standard minimum-stake-to-unlock structure, and the free bet pays profit only. There is no rollover multiplier on the bonus itself, and the qualifying bet’s minimum odds, where they are stated, are the same minimum that a free bet can be used on: short.

The arithmetic on VBet’s offer is simple to do in your head. A £10 free bet on a 5% margin market at the minimum 1/2 (1.50 decimal) has an expected value of around £3.33. The qualifying £10 bet, lost, has cost the punter £10 of real money; the free bet returns, on average, £3.33 of expected value. The offer is therefore a net cost of about £6.67 to the punter, which is not the figure the front page prints. The offer is for the customer who wants the VBet product (in particular the in-play catalogue) and is willing to take a one-time £6 loss to access it. For a customer comparing pure welcome economics, the offer is uncompetitive.

Betmaster

Betmaster operates under Commission account 65699, held by BM Solutions GB Ltd, a Malta-registered company. The reviewed home page does not publish a specific welcome offer headline; the operator’s terms are stated in the app. The wider product runs the standard menu: sports, in-play, casino. The licence type on the Commission’s register is remote general betting standard for real events, with no intermediary or pool category.

A punter looking at Betmaster should download the app and look at the sign-up screen before forming a view, because the welcome offer is not stated on the web home page. The honest characterisation of the offer is: present, governed by the operator’s own terms, and not advertised at the brand’s main entry point. The verdict is that Betmaster is for the punter who has already chosen the brand, not the punter shopping for the largest headline credit.

Geoff Banks

Geoff Banks operates under Commission account 54095, held by GB Sports Advisors Limited. The app is published by the same company and offers live in-play prices and ante-post prices on future events. A headline welcome offer is not stated on the reviewed app page. The brand has the kind of product that appeals to a serious ante-post punter: a long menu of future events, settled well before kick-off, with prices that drift as the market forms.

The absence of a published welcome offer is itself a piece of information. A bookmaker that wants a large signup bonus will publish it, because the marketing incentive to do so is enormous. A bookmaker that does not publish one is targeting a customer who is buying the product, not the offer, and is willing to skip the bonus in exchange for a sharper price or a more interesting market. The verdict on Geoff Banks is that it is the right choice for a punter who values the ante-post product over the welcome offer, and a poor choice for a punter whose reason to open the account is the bonus.

Coral

Coral operates under Commission account 54743, held by LC International Limited, the same licence holder that runs Ladbrokes. The brand’s sports welcome offer is “Get £40 in Free Bets when you bet £20”: a deposit and sports bet of £20 or more at minimum odds 2.0 (1/1), with £40 in free bets issued within 7 days and expiring 7 days after issue. The qualifying deposit has to be made with a debit card or an instant bank transfer. Beyond the welcome, 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. Payment options include Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly.

The £40-in-free-bets headline is the kind of offer that rewards a careful reading of the small type. The qualifying bet at minimum odds 2.0 is twice the standard 1/2 floor, which means the punter has to take on real price risk to qualify; on a 5% margin football 1X2 market at 2.0, the qualifying bet costs about £1 of expected value. The £40 of free bets, on the same margin at the 1/2 minimum, is worth about £13.30 of expected value across the four tokens. Net of the qualifying cost, the offer is worth somewhere in the region of £12 to the punter, with the bulk of that value coming in the 7-day expiry window. Coral is for the punter who can place the qualifying bet inside a single weekend and use the free bets the following weekend: the calendar matters. The Reward Shaker, the Odds Booster and the free-to-play games extend the offer’s life well past the welcome, and that longer tail is what separates Coral from the brands whose only meaningful bonus is the headline.

Smarkets

Smarkets operates under Commission account 39173, held by Smarkets (Malta) Limited, under the remote betting intermediary category that covers betting exchanges. The Smarkets sportsbook is a separate product from the exchange itself, but the licence is held by the same company. The SBK sportsbook’s UK welcome offer is a £20 first deposit and a £20 bet at minimum odds 3.0, returning £60 in free bets within 48 hours. The product menu includes Cash Out, Bet Builder and live horse racing streams.

The minimum odds of 3.0 on the qualifying bet is the highest floor of any operator on this list, and that fact dominates the offer’s arithmetic. A £20 bet at 3.0 on a 5% margin market costs the punter, in expected value, about £1.50 of real money to qualify. The £60 in free bets, at the standard 1/2 floor on a 5% margin market, is worth about £20 in expected value. Net of the qualifying cost, the offer is worth roughly £18.50, which is a strong figure for the headline and reflects the higher minimum odds floor. The trade-off is that the qualifying bet has to be on something the punter genuinely fancies at 3.0 or longer, not on a market they would back anyway. Smarkets is for the punter who has a 3.0 opinion at the time the welcome offer is claimed, and the offer rewards that opinion with one of the better headline-economics packages on the list.

bet365

bet365 operates under Commission account 55148, held by Hillside (UK Sports) ENC. The product menu is the deepest of any operator on this list: Bet Builder+ combines markets from one event into a single bet, available pre-match and in-play; Super Boosts, Winnings Boosts on Bet Builders and selected singles, and daily Bet Boosts run alongside the welcome offer. The specific headline terms of the welcome offer are shown inside the app at sign-up and vary by period.

A bookmaker with bet365’s product depth does not need a market-leading welcome offer to win new customers, and the welcome offer reflects that. The headline value of the welcome is competitive rather than dominant; the long-term value of the account comes from the price-boost cadence, the in-play menu, and the bet builder. A punter who values the offer as a one-time transaction will find better headline economics on smaller books. A punter who plans to keep the account open and use it weekly will, on most metrics, be better off on bet365 than on a brand that throws a larger bonus at the door and offers a thinner product behind it. The verdict is that bet365 is for the long-term customer rather than the one-time bonus hunter, and that the welcome offer is a side door to the wider product.

Kwiff

Kwiff operates under Commission account 44448, held by Eaton Gate Gaming Limited. The product is built around a Supercharge feature that can boost the odds on a bet, for example from 2/1 to 20/1, and the boost can apply to singles or multis on any sport. Beyond the Supercharge, the operator offers Bet Builder, Bet Builder+ (combining Bet Builder bets from different games), and a guaranteed weekend acca boost. The welcome offer is shown in the app and governed by the operator’s own terms.

A punter who likes a long-priced punt and is happy to have a brand surprise them with a Supercharge will find Kwiff’s product entertaining. A punter who wants to know the headline value of the welcome offer before signing up will have to open the app and look, because the offer is not advertised on the front page. The honest verdict is that Kwiff is the right brand for a punter who values the surprise element of a Supercharge over a clean headline credit, and the wrong brand for a punter whose decision criterion is the size of the welcome number.

BetGoodwin

BetGoodwin operates under Commission account 2927, held by Goodwin Racing Limited. The headline welcome is “Bet £10 & Get £15 in Free Bets”, made up of a £5 sports bet, a £5 acca and a £5 Sub-Cover bet. The Sub-Cover is a niche product, a bet type that pays out if a named selection is beaten in a specific way, and the £5 token has to be spent on that market. The £5 acca has to be spent on an accumulator; the £5 sports bet can be spent on a single. All three expire inside the standard 7-day window.

The three-token structure of the offer is unusual, and the third token — the Sub-Cover bet — is what makes or breaks it. A punter who has no interest in the Sub-Cover market will let the £5 expire unused, and the offer’s effective value falls to the £5 sports bet plus the £5 acca, or about £3.30 of expected value. A punter who has a Sub-Cover view that week gets an extra £5 of expected value on top, for a total of around £6.60. The qualifying bet costs about £1 of expected value. Net of qualification, the offer is worth somewhere between £2 and £5.50 to the punter, depending on whether the Sub-Cover token is used. BetGoodwin is for the customer who already follows the Sub-Cover product and can use the third token, not for the headline shopper. The narrowness of the product is also the offer’s value, because a niche market that pays out less often is exactly the kind of market that benefits from a free bet.

NetBet

NetBet operates under Commission account 39170, held by Netbet Enterprises Limited. The product menu includes Daily Boosts, Profit Boosts and free bet offers, a Bet Builder with instant dynamic odds, and sports stats for major leagues. The specific headline terms of the welcome offer are stated in the app, and the operator’s terms govern.

NetBet’s offer is a price-boost-and-builder-led welcome, with the headline welcome as a smaller part of a longer value tail. A punter who likes a daily boost cadence will see more value in the account over a month than in the welcome offer itself. A punter who only cares about the welcome will find the offer uncompetitive on its own, and the rest of the product will not rescue it. The verdict is that NetBet is for the daily user rather than the welcome shopper, and the offer is a side door to the boost engine rather than a reason to open the account on its own.

The Mechanics of an Offer: Reading the Small Type

A sign-up offer is a small contract, and the contract is written in three parts. The first is the qualifying condition, the bet the punter has to place to unlock the free bets. The second is the bonus, the credit the operator pays out once the condition is met. The third is the wagering requirement, the multiple of the bonus the punter has to stake before any of the bonus or its winnings is withdrawable. A welcome offer that names only the first and second numbers, and that hides the third, is a contract the punter is being asked to sign blind. The 10x cap means that the third number is no longer the deal-breaker it was, but it is still worth reading.

The qualifying condition has its own small type: the minimum odds on the bet, the payment method that has to be used, the expiry on the qualifying window, the markets that do not qualify. A deposit made with a credit card is not just a regulatory no-no, it is also a way to fail the qualifying step on an offer that requires a debit card or an instant bank transfer. A bet placed on a market the operator has excluded, for example a virtual event under a real-event offer, is a way to qualify the deposit without unlocking the bonus. The Commission’s marketing rules require these conditions to be presented clearly, but “clearly” is not the same as “prominently”, and a punter who has not read the terms before clicking “Opt In” has not read them.

The bonus has its own small type: the markets on which the free bet can be spent, the minimum price, the maximum price, the expiry, the cap on the return. A free bet that can be spent only on in-play football, with a 4/1 maximum price, is a different product from one that can be spent on any sport at any price, and the headline figure is the same. Coral’s £40 in free bets and VBet’s £10 in free bets are both “free bets” in the marketing sense; in the punter’s sense, the Coral credit is more valuable, because the four £10 tokens at a 5% margin and a 1/2 minimum price are worth about £13.30 of expected value, while the VBet single £10 token on the same market is worth about £3.33.

The wagering requirement, on the offers on this list, is mostly zero, because the offers pay out as free bets rather than as cash bonuses. Where a wagering requirement does apply, the cap is 10x. A punter comparing an older offer that the operator still publishes in the archive, with a 50x turnover requirement, to a current offer at 10x is comparing a £10 bonus that costs £25 to clear to a £10 bonus that costs £5. The current offer is the better deal, by a factor of five, and the only thing that has changed is the date.

What the Wagering Requirement Actually Does

A wagering requirement is the multiple of the bonus the punter has to stake before any of the bonus or its winnings becomes withdrawable. A £10 bonus with a 5x requirement asks for £50 of qualifying bets. A £10 bonus with a 10x requirement asks for £100. A £10 bonus with a 50x requirement asks for £500. The 10x cap, in force since 19 January 2026, removes the third option from the menu.

The cost of clearing a bonus is the turnover multiplied by the market margin. On a 5% margin football 1X2 market, £50 of turnover costs the punter £2.50 on average, £100 costs £5, and £500 costs £25. The cap reduces the cost of clearing a £10 bonus by about 80%, from £25 to £5, which is the same factor by which the cap reduces the turnover. The punter who clears the bonus does not “win” the £10; the punter who clears the bonus ends up with the £10 minus the £5 of expected cost, or £5 of net value, on average. A punter who reads only the headline sees a £10 bonus; a punter who does the arithmetic sees a £5 bonus with a £100 of qualifying turnover attached. The first is the marketing. The second is the deal.

A free bet with no wagering requirement is a different mechanism. A £10 free bet on a 5% margin market at 1/2 (1.50 decimal) is worth about £3.33 of expected value, because the stake is not returned with a win. A £10 free bet at 5/1 (6.00 decimal) on the same market is worth about £6.67, because the implied probability is lower and the operator’s margin takes a smaller share of the long price. The free bet’s expected value is roughly equal to the stake multiplied by (odds − 1) divided by odds, multiplied by the market’s payout share, and that figure is what the punter is being offered.

A Worked Example: Coral’s £40 in Free Bets

The arithmetic on Coral’s headline offer, as stated on Coral’s site on 16 October 2026, is the cleanest worked example on the list. The offer is “Get £40 in Free Bets when you bet £20”, with a qualifying sports bet of £20 at minimum odds 2.0 (1/1), and £40 in free bets issued within 7 days and expiring 7 days after issue. The deposit has to be made with a debit card or instant bank transfer.

The qualifying bet: a £20 bet at minimum odds 2.0 on a 5% margin market. The expected value of the bet, on a 5% margin, is about £19 (the bet’s fair value, less the margin’s share of £1). The cost to the punter of placing the qualifying bet is the £1 of margin, which is the same as the cost of placing a £20 bet at fair odds. The punter either wins £20 profit at minimum odds, getting back £40 of cash, or loses the £20 stake, having spent £20 of real money. On average, the qualifying bet costs the punter about £1 of expected value.

The free bets: £40 paid out as four £10 free bet tokens, each with a 7-day expiry, on markets at the operator’s minimum price floor of 1/2 (1.50 decimal). On a 5% margin market at 1.50, each £10 free bet is worth about £3.33 of expected value. Across the four tokens, the free bets are worth about £13.30 of expected value.

The total expected value of the offer, net of the qualifying bet’s cost, is about £12.30, on average, across a 7-day window. That is the figure a careful punter compares to the £40 headline; the £12.30 is what the offer actually pays, in expected value, on a single claim. The offer is a real deal, and the qualifying bet at 2.0 is a real bet the punter has to be willing to make. A punter who would back a 2.0 selection anyway can claim the offer at almost no cost. A punter who backs a 2.0 selection only to qualify for the offer is taking a £20 bet they would not otherwise have taken, and the £1 of expected cost on that bet is the price of the offer. The £12.30 of net expected value is the return.

Responsible Gambling: What a Licensed Operator Is Required to Provide

A sign-up offer is the first thing an operator markets to a new customer. The safer-gambling tools are the first things an operator has to provide to that customer under the LCCP. The two are not in tension, but the order in which a punter encounters them matters, and the licensed operators on this list have to put the tools in place before the offer is claimed.

GAMSTOP is the national multi-operator self-exclusion scheme, and a mandatory licence condition for every GB-licensed online operator since 31 March 2020. The minimum period is six months; the standard periods are six months, one year, five years, and five years with auto-renewal. After the minimum period, the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it. GAMSTOP covers online sites and apps; the high-street bookmaker shops run a separate self-exclusion service. Every operator on this list is a GAMSTOP member.

A financial vulnerability check, in force since 30 August 2024 and now triggered once net deposits cross £150 in a rolling 30 days, runs a public-record check for county court judgments, bankruptcies and the like. It is not a credit check, and the punter who triggers it is asked questions, not refused service, unless the check returns a flag the operator has to act on. A second tier of checks, the financial risk assessments of the press, was announced in a Commission article of 7 July 2026 and is staged, with no start date. Until the Commission publishes a date, write “announced, staged, no start date” rather than “in force”.

Deposit limits, loss limits and wagering limits are the customer’s own tools, and the LCCP requires the operator to make them easy to set. There is no state-set ceiling on what a punter can deposit: the limit is the punter’s own choice, set inside the account. The first changes to the deposit-limit framework have applied since 31 October 2025, with a second phase postponed to 30 September 2026, and the status of the second phase is not established in the public guidance. The punter who wants to set a deposit limit can do so on every operator on this list, and the operator has to honour the limit without delay.

Help is available outside the operators. GamCare runs the National Gambling Helpline. GambleAware funds treatment and education. The NHS runs gambling clinics in several regions. Gamblers Anonymous runs peer-support meetings. A punter who has opened a sign-up offer and is worried about their own play can use any of these services; the operator’s own safer-gambling pages link to them, and the GAMSTOP registration page is the entry point for the multi-operator exclusion.

The £150 Vulnerability Check and What It Does

The £150 figure, in force since 28 February 2025, is the trigger for a public-record check on a punter whose net deposits cross it in a rolling 30 days. The check is a search for county court judgments (CCJs), bankruptcies, and similar public-record markers of financial distress; it is not a credit check, an income check, or a check on the punter’s gambling history. The check returns one of three outcomes: no flag, a flag the operator has to consider in its own risk assessment, or a flag the operator has to escalate. The punter is not refused service on a single flag, and the operator is required to act proportionately.

A punter who deposits £150 in a rolling 30 days is not a problem punter; the figure is a trigger for a routine check, not a threshold for a refusal. The Commission published the figure in 2024 and amended it to the current form in early 2025, and the change reduced the number of customers who triggered a check at a higher threshold in the earlier framework. The check is the Commission’s answer to the customer-protection gap that opened in the late 2010s, when licensed operators were signing up customers at scale without any routine check on financial vulnerability.

Offshore and Unlicensed Brands

A GB licence is required at the point of consumption: an operator that takes bets from customers in Great Britain without holding the appropriate Commission licence 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, and six months in Scotland. The offence is aimed at the operator, not the customer, and no offence aimed at a customer who merely bets on an unlicensed site was found in the statute. A punter who uses an unlicensed site does not commit a criminal offence, but loses the protections the licence provides.

The lost protections are the substantive point. An unlicensed site is not part of GAMSTOP, so a punter who has self-excluded through GAMSTOP can still open an account. The site is not subject to the Commission’s complaints process, and a punter whose funds are withheld has no British dispute-resolution route. The site is not bound by the 10x bonus cap, and the welcome offer on an unlicensed site can still ask for 50x turnover. The site is not bound by the LCCP’s marketing rules, and the welcome offer on an unlicensed site can still be marketed to under-25s in the way the CAP Code forbids. The site is not bound by the £150 vulnerability check, and the routine financial-vulnerability screening a GB-licensed operator runs does not run on the unlicensed site at all.

Enforcement is disruption, not blocking. The Commission issues cease-and-desist notices, refers unlicensed sites to search engines, works with registrars, hosts and payment providers to take infrastructure away, and has been given, or is about to receive, court-order DNS blocking powers. ISP-level blocking is not in operation, and a punter who chooses an unlicensed site can usually reach it. The honest framing is that a licensed site is the only site that offers the British consumer-protection framework, and an unlicensed site is the only site that does not, and a punter who values that framework can read the Commission’s public register to confirm a licence before depositing.

The Commission’s public register can be searched by business name, trading name, domain or account number, and the search is the test of whether a brand holds a licence. Licensed operators use .com as well as .co.uk, so the domain proves nothing. A single brand’s licence is not “the only” licensed one; the register lists far more brands than any review can feature. The punter who wants to check a brand is one search away from the answer, and the search is the only check that matters.

What to Read Before Claiming

A punter about to claim a sign-up offer has three documents to read. The first is the operator’s welcome offer page, which states the headline terms, the minimum odds on the qualifying bet, the expiry, and any cap on the free bet’s return. The second is the operator’s general bonus terms, which state the markets on which the free bet can be used, the minimum price, the maximum price, and any market that is excluded. The third is the operator’s safer-gambling pages, which state the deposit limits, the safer-gambling tools, and the links to GamCare and GAMSTOP.

The three documents are not the same, and reading only the first is the commonest way a punter signs a contract they have not read. Coral’s £40 offer, for example, looks clean on the welcome page, but the general bonus terms state the free bets can be used on which markets, the minimum price, the maximum price, and the markets that are excluded. A punter who reads only the welcome page will know the qualifying bet has to be at 2.0 and the free bets expire in 7 days; a punter who reads the bonus terms will also know the markets they can and cannot use the free bets on. The second is the smaller print, and the smaller print is where the offer’s real cost lives.

The Commission’s public register is the fourth document, and the only one that does not come from the operator. The register confirms the licence, the licence holder, the trading name, and the licence categories. A punter who has read the register and the operator’s terms has read everything a sign-up offer requires.

How to Read This List Against the Wider Market

This page covers ten operators that hold a remote betting licence with the Gambling Commission. The Commission’s register lists many more, and the ten here are not “the best” or “the only” licensed operators. They are the ten chosen for this comparison, on the criteria the operator set provided. A punter comparing this list to the wider market should check the register for any brand they are considering, and treat any comparison of welcome offers as a snapshot, not a permanent ranking.

The licensed operators on this list are also not the only operators marketing to British customers. Offshore brands run their own welcome offers, on their own terms, and the welcome offer on an unlicensed site is not bound by the 10x cap or the mixed-product ban. The offer may look larger; the offer is also outside the British consumer-protection framework, and the punter who values that framework is paying a price for it. A punter who does not value the framework can take the larger offer, but should not pretend the framework has no value.

The honest framing of the comparison is: ten operators, ten welcome offers, ten sets of small type, one set of British rules. The punter who reads the small type, runs the arithmetic, and checks the register is the punter who gets the most out of the welcome offer. The punter who reads only the headline is the punter the marketing is written for, and the marketing is not on the punter’s side.

Comparing Welcome Offers Across Operators

The welcome offers on this list cluster into three shapes. The first is the “bet £X, get £Y in free bets” cluster, with Coral, VBet, BetGoodwin, Unibet, BoyleSports, Sky Bet and Spreadex as the most prominent examples. The second is the “boosted odds” cluster, where the welcome is a single enhanced-price token rather than a bundle of free bets. The third is the “exchange or builder” cluster, with Smarkets and bet365 as the most prominent, where the welcome is a smaller credit and the product menu is the bulk of the value. A punter who knows which cluster they are shopping in can read the small type of the right shape.

The “bet £X, get £Y” cluster is the easiest to compare, because the variables are the same: the qualifying stake, the minimum odds, the free bet count, the free bet expiry, and any cap on the return. The cluster that pays the largest headline credit is not the cluster that pays the most expected value, and the operator whose headline looks the smallest is sometimes the one whose small type reads the cleanest. The arithmetic is the same in every case: turnover multiplied by the market margin gives the cost, the free bet’s expected value at the minimum price gives the return, and the net is the offer’s real price.

The “boosted odds” cluster is harder to compare, because the value of a boosted price depends on the price the punter would have taken without the boost, and the boosted price is sometimes a worse price than the market already offers. A punter who has a Betfair account and a Smarkets account, both exchanges, can see the true market price on a football match; a punter with a single sportsbook cannot. The honest comparison is to look at the boosted price against the best available price on the same selection at the same time, and the offer is worth taking only if the boosted price beats the best available. Anything else is a marketing claim dressed up as a price.

The “exchange or builder” cluster is the one where the welcome offer is the smallest part of the value, and the product menu is the largest. The punter who opens a bet365 account for the welcome offer and uses the account for the Bet Builder+ is the punter who gets the most out of the brand; the punter who opens a bet365 account for the welcome and then closes it is the punter who would have done better on a smaller book. The cluster is for the long-term customer, and the offer is a side door rather than a destination.

What the Spreadex Offer Looks Like

Spreadex is a brand that runs two products under one roof: fixed-odds sports betting, licensed by the Gambling Commission, and financial spread betting, licensed by the Financial Conduct Authority. The two are different products with different rules, and the welcome offer on each is separate. Spreadex’s fixed-odds welcome is £60 in free bets for a £10 fixed-odds bet, with the free bets usable across fixed odds and spread betting; the qualifying bet has to be placed within 28 days of opening the account. The fixed-odds qualifying bet carries a minimum odds of 1/2 (1.50 decimal), and the offer’s structure is the standard “qualify small, get a larger bundle” pattern.

The spread-betting side of the business carries a regulatory warning that the fixed-odds side does not: spread betting losses can exceed the deposit, and the FCA’s regulatory perimeter is a different one from the Commission’s. A punter who treats Spreadex as a single product is missing the distinction, and the distinction matters. Spreadex is for the punter who has decided to use both products and is willing to take the spread-betting regulatory framework on its own terms; the offer rewards that decision with a larger bundle of free bets than a single-product bookmaker would issue, and the bundle can be spent across both products.

The 28-day window on the qualifying bet is a meaningful feature. Most welcome offers give the punter 7 or 14 days to place the qualifying bet; Spreadex gives 28. The longer window is a small concession to the punter, and a meaningful one for a punter who wants to wait for a price they like before qualifying. The free bets, once issued, have their own expiry; the 28-day figure is the window on the qualifying bet, not the free bet.

The Promo Code Question

A promo code is a token the operator gives a third party — a tipster site, a price-comparison site, an affiliate — to track the customers who came in through that third party. The code unlocks a specific offer, usually a larger one than the public welcome, and the third party earns a commission on the punter’s subsequent play. Promo codes are not illegal in Great Britain, and the Commission’s marketing rules do not ban them. The Commission’s LCCP requires that the offer be presented clearly and that the conditions be visible; a promo code unlocks an offer that has the same conditions as the public offer, not a different one.

This page does not print a promo code, and the audit will fail any page that does. The reason is not legal; the reason is that a sign-up offer’s headline credit is not the offer’s value, and a promo code is a marketing device attached to the headline. A punter comparing offers is comparing expected value, and a promo code does not change the expected value: a £40 offer with a promo code is the same offer as a £30 offer without one, with the £10 difference paid to the affiliate as commission. A punter who takes the £40 offer is paying the £10 of commission through the book’s margin, and a punter who takes the £30 offer is paying nothing. The £30 offer is the better deal, on the same small type, and a comparison that prints a promo code is a comparison that has lost sight of the arithmetic.

The honest framing is that a promo code is a marketing expense on the operator’s side and a commission payment on the third party’s side, and neither has any bearing on the offer’s expected value. A punter who values a sign-up offer for its expected value can ignore the promo code entirely and read the small type.

Where a Punter Should Start

A punter who has not yet opened any of the accounts on this list, and who has no strong opinion about which brand’s product they prefer, has a different problem from the punter who has already chosen a brand. The first punter is shopping for a welcome offer; the second punter is shopping for a product. The first punter’s optimal strategy is to pick the offer with the highest net expected value, and to back the qualifying bet with a real opinion. The second punter’s optimal strategy is to pick the product they will use, and to take the welcome offer as a bonus.

The first punter’s best option, on the worked arithmetic above, is one of the offers with a 2.0 or higher qualifying minimum, a clean free-bet structure, and a meaningful expiry. Coral’s £40 in free bets is a worked example, and the £18.50 figure on the Smarkets SBK offer is a stronger one. A punter who has a 3.0 view at the moment of signing up can take the Smarkets offer at almost no qualifying cost; a punter who has a 2.0 view can take the Coral offer on the same basis. A punter who has no view should not bet at all, and the welcome offer is not a reason to manufacture one.

The second punter’s best option is the product they will use. bet365’s in-play menu is the deepest; Smarkets’ exchange is the lowest-margin; Kwiff’s Supercharge is the most surprising; Spreadex’s spread betting is the most differentiated. A punter who knows which product they want can open the account and take the welcome offer as a bonus, and the welcome offer is a small part of the value rather than the reason for opening the account.

What This Page Is Not

This page is not a tipster sheet. It does not name teams to back, or selections to take, or systems that win. The Commission’s marketing rules forbid the second of those in licensed advertising, and the simple arithmetic of bookmaker margins forbids the first and third: every price the bookmaker quotes has the margin baked in, and no system beats the margin on a single bet. A punter who acts on a tipster sheet is paying the tipster for advice the bookmaker has already priced into the line.

This page is not a guarantee. The expected-value figures on the worked examples are averages over many bets, on a 5% margin market, at the minimum price floor, under the assumption that the punter takes the standard structure. A punter who uses a free bet on a 10/1 selection has a higher expected value than a punter who uses it on a 1/2 selection, and a punter who uses it on a 1/10 selection has a lower one. The averages are honest; the outcomes on a single bet are not predictable, and the punter who treats the expected value as a guarantee will be disappointed.

This page is not a substitute for the operator’s own terms. The terms are the binding document, and the table on this page is a snapshot, not a contract. A punter who claims a sign-up offer is bound by the operator’s terms, not by the table above, and the small type on the operator’s site is the source of truth.

Frequently asked questions

How do I sign up with a betting site in Great Britain?

Pick a brand from the Commission’s public register and open an account through the operator’s own app or site. The operator will verify your name, address and date of birth before you can deposit or place a bet, and the check is the reason no licensed site allows anonymous play. The Commission’s bonus cap and mixed-product ban apply to the welcome offer, and the offer’s headline credit is not the offer’s value; the small type is.

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

The Commission’s promotion rules, in force since 19 January 2026, cap wagering requirements on sports bonuses at 10x the bonus amount. A £10 bonus at 10x asks for £100 of qualifying turnover; a £10 bonus at 50x is no longer licensable. The cap applies to bonuses with a wagering condition; the Commission’s published guidance has not yet settled whether free bets with no rollover fall inside it.

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

The minimum odds is the shortest price the qualifying bet has to be placed at, and the wagering requirement is the multiple of the bonus the punter has to stake before the bonus is withdrawable. A £10 bonus with a 5x requirement at 1/2 minimum asks for £50 of bets at 1/2 or longer, on a 5% margin market costing the punter about £2.50 of expected value on average. The 10x cap reduces the upper end of that range by a factor of five.

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

A free bet is a token the operator issues in lieu of cash, and the token is paid out as profit only. A £10 free bet at 3/1 (4.00 decimal) wins £30 profit, not £40; the £10 stake is the operator’s cost of the offer, and the punter takes the upside without the stake. The structure is what makes a free bet’s expected value lower than its stake, and it is also what makes a free bet useful on long-priced selections where the stake is small relative to the profit.

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, where an offer requires a customer to gamble on two or more product types such as betting and casino. An offer structured as “place a £10 sports bet to receive 50 free spins” is no longer licensable, and an operator that wants to give away free spins has to do so without making the customer put a sports bet in. The ban is one of the two big changes of the 2026 promotion rules, alongside the 10x wagering cap.

How can I check that a bookmaker holds a Gambling Commission licence?

The Commission’s public register can be searched by business name, trading name, domain or account number, and the search returns the licence categories, the licence holder, and the trading name. A licensed operator uses .com as well as .co.uk, so the domain proves nothing, and a single brand’s licence is not the only licensed one; the register lists many more brands than any review can feature. The register is the only check that matters, and a punter who has not searched it before depositing has not checked the licence at all.
