A welcome offer is the cheapest free marketing a bookmaker has, and it is the most expensive marketing a bettor signs up for. The headline number is the bait; the cost sits in the fine print. Minimum odds decide which bets count. A wagering requirement decides how much has to be staked before anything can be withdrawn. An expiry date decides how long the bettor has to clear it. And in Great Britain, the Gambling Commission has put a ceiling on one of those terms — wagering on bonuses may not run above ten times the bonus amount, and mixed-product deals are out — which changed the kind of offer a UK-licensed site can advertise from 19 January 2026. That rule sits at the centre of this page, because it is the line that turns a flashy number into an arithmetic problem.

Data current as of October 30, 2026, cross-referenced against the Gambling Commission’s public register of licence holders.

How a Welcome Offer Is Built

Every sign-up deal in this market is one of four shapes, and the shape decides what it costs.

A deposit-match bonus adds a percentage of the first deposit as bonus funds, typically 100 per cent, with a cap. The bonus is not real money until a turnover requirement has been met, and the deposit itself is usually locked in too. A £20 bonus at 10x means £200 of qualifying bets before any winnings withdraw.

A free bet credits a fixed stake that can be placed once, usually without returning the stake itself when the bet wins. A £10 free bet at odds of 3.00 wins £20, not £30. It is the most common welcome format in the UK.

A refund-as-free-bet offer, sometimes sold as “risk-free”, returns a losing first bet as a free bet rather than cash. The first bet’s stake is gone; what comes back is a one-shot token with the same expiry and the same odds floor.

A price boost improves the odds on a specific market for new sign-ups only, returning the stake normally. The gain is real money but capped at a small stake limit, so the upside is bounded.

What makes an offer cheap or expensive is never the headline. The wagering requirement, the minimum odds, the expiry window and whether the stake is returned do the work — and the Commission cap on wagering sets a hard ceiling on the first of those.

The Wagering Cap in Force Since 19 January 2026

Since 19 January 2026, a UK-licensed bookmaker cannot set a wagering requirement above 10x on any bonus. A bonus of £10 may demand at most £100 of qualifying stakes before withdrawal. The rule also bans any promotion that mixes product types — an offer that asks the bettor to wager on betting and casino, or on betting and bingo, in exchange for one reward. The change has narrowed the field: heavy casino-style rollover bonuses, the 40x and 50x deals that still tilt the offshore market, no longer have a GB-licensed route to the customer.

What the rule does not do is decide the value of a free bet. A free bet whose stake is not returned on a win carries no wagering condition by design — the bettor either wins on the single bet or loses the token — and the Commission’s published materials do not settle whether the cap still applies in that case. Free bets with a turnover multiplier attached, the rarer shape in this market, sit clearly inside the 10x ceiling. Operators that issue free bets without a rollover keep the term simple: place the token, win or lose, the deal is closed.

The practical effect for a bettor is shorter clearance windows on cash bonuses and a welcome market dominated by free bets and short refund offers. Bigger headline numbers, the £100-and-up matches, are no longer the standard first move on a GB-licensed site.

Minimum Odds and the Expiry Window

A wagering requirement is meaningless without the bets that clear it, and a bet does not clear it unless the odds sit at or above the floor the operator sets. The floor is nearly always a fraction above evens, with 1/1 (decimal 2.00) the standard welcome-offer minimum and 3/5 (1.60) or 1/2 (1.50) appearing on the gentler end. A bettor clearing a £100 turnover at a £5 stake must place twenty bets, and any one of them at odds shorter than the floor adds nothing to the count. On accas, the rule shifts: most welcome offers that take accas as qualifying bets require every leg to clear the floor, not the combined price, so a four-fold with three legs at 1.40 and a fourth at 6.00 will not count.

Expiry is the second clock. Seven days from issue is the common window for welcome free bets in this market, with 30 days appearing on cash bonuses and shorter windows — sometimes 48 hours — on refund deals. A free bet that expires before the bettor has found a market at the right odds is a free bet that paid nothing, and the value calculation is not the headline minus the stake but the headline times the chance of clearing it inside the window.

What the stake is not returned with the winnings is the third leg of the cost. A £10 free bet at odds of 3.00 returns £20 of profit, not £30. The bettor’s effective price is lower than the decimal odds suggest, and the gap widens at shorter prices. At odds of 2.00 the bet pays £10 from a £10 token, halving the headline odds; at odds of 5.00 the bet pays £40 from the same £10 token, an effective price of 5.00 in real-money terms. The closer to evens the offer sits, the more the stake-not-returned rule costs.

The Cost Behind the Headline

Three of the offers reviewed on this page have a £40 free bet for a £20 qualifying bet at minimum odds of 2.00, a construction the bookmaker markets as a “£40 welcome”. The headline is the £40. The cost is the £20 the bettor must stake on a single bet at minimum odds of 2.00 to release it, plus the chance that the £20 bet loses, which is a real risk at evens on a market with a margin. The £40 token itself pays £80 of profit if it wins at 3.00 and £40 of profit if it wins at 2.00, with the stake gone either way.

Add a £10 free bet for a £10 first bet that loses, a “risk-free” framing that returns a token rather than cash, and the cost is the expected loss on a £10 bet at minimum odds — typically between 50p and £1 in margin depending on the market — plus the chance the token expires unused. Refund-as-free-bet offers carry a doubled cost: the first stake is at risk, and the token that comes back is single-use, expires fast, and does not return its stake.

A 50 per cent back-as-free-bet up to £50, the shape one of the operators below runs, sets the cap at the qualifying stake. A £100 first bet that loses returns a £50 token — half the loss, not the full amount, and again as a token. The marketing word is “back”; the arithmetic is “half”.

What This Page Covers

The ten UK-licensed bookmakers below are the comparison set. Each is on the Gambling Commission’s public register against a holder of a remote general betting licence for real events. Every offer is described as that operator’s own terms state it, with no promo code and no “risk-free” framing taken at face value. The angle is cost: what each offer asks of the bettor, what it returns, and where the deal is kind or thin.

A small number of the featured brands run spread betting alongside fixed odds, and one is paired with a betting exchange under a related operator. Where a brand carries a related product, the welcome deal covered is the fixed-odds sportsbook offer; spread betting and exchange fees have their own terms and their own costs.

Licensing and the Public Register

Every brand reviewed here holds a Gambling Commission remote licence for general betting on real events. The licence is the test: a GB-licensed remote operator must verify name, address and date of birth before the first deposit, must enrol the customer in GAMSTOP if the customer has self-excluded elsewhere, must offer deposit limits as a default option, and must run the financial-vulnerability check on accounts that pass £150 of net deposits in a rolling 30 days. The Commission’s public register is searchable by business name, trading name, domain or licence account number and is the authoritative list.

A licence is not a recommendation, and being on this page is not a ranking. Several brands can run under one licensee, and a place in the comparison is a description, not an endorsement. The order of the write-ups below is fixed by the spec and carries no implied preference.

Responsible Gambling and the Customer’s Own Levers

GAMSTOP is the multi-operator self-exclusion scheme, mandatory for every online operator in this market since 31 March 2020. Periods run six months, one year, five years, or five years with auto-renewal, and after the minimum period the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it. Online coverage is the rule; betting shops use a separate service.

Deposit limits are the bettor’s first lever. A licensed remote operator must offer a gross deposit limit on a fixed time frame, with the first phase of changes applying since 31 October 2025 and a second phase postponed to 30 September 2026 — the live status of that second phase is not established. There is no state-set ceiling: limits are the customer’s own choice, and a tighter cap is the cheapest form of safer gambling available.

Help is reachable through GamCare and its National Gambling Helpline, through GambleAware, and through NHS gambling clinics for face-to-face support. Gamblers Anonymous runs peer-led meetings across the country. A bettor who has set a deposit limit and feels the limit slipping has, at every licensed operator, the route to a self-exclusion that closes the account.

Coral

Coral runs the standard £40 free bet for a £20 qualifying bet at minimum odds of 2.00, with the free bet issued inside seven days and expiring seven days after issue. The offer is opt-in, GB-only on new accounts, and the qualifying deposit and bet must come off a debit card or instant bank transfer — Apple Pay, Visa, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly are all listed on the deposit page, but the welcome promo is closed to those routes. The free bet is the headline; the £20 qualifying bet is the cost, and the seven-day window on the token is the clock.

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 — recurring promos that share the same seven-day window on the free-bet tokens they issue. The licence is held by LC International Limited under Commission account 54743. Coral and Ladbrokes sit under the same licensee and share infrastructure.

For the bettor, the deal is the market’s median rather than its peak — £40 for £20 is common ground — and the value sits in the acca insurance, the odds boosts and the Super Series free entry that come with the account. A customer who does not clear the £40 token inside seven days pays for the £20 qualifying bet and gets nothing back.

Spreadex

Spreadex combines a fixed-odds sportsbook and a spread betting book, which makes it the most hybrid name on this list. The new-customer offer is £60 in free bets for a £10 fixed-odds qualifying bet at minimum odds of 1/2, with the qualifying bet to be placed within 28 days of opening the account. The 28-day window on the qualifying bet is unusually generous; the £60 token is the largest fixed-odds free bet on this page relative to the qualifying stake. Spreadex also runs Acca Boosts that give a cash boost from 5 per cent up to 100 per cent on football accumulators of three or more selections, paid in cash rather than as a free bet — a rare shape on this market.

The catch is in the spread book. Financial spread betting is regulated by the FCA rather than the Commission, and losses on spread bets can exceed the deposit. A new Spreadex account opens both, and the customer should treat the two books as separate products with separate costs. The fixed-odds welcome offer is the cheaper side; the spread book is the side that has historically hurt customers who did not read how a spread bet settles. The licence for the fixed-odds book is held by Spreadex Limited under Commission account 8835.

For a bettor who wants a fixed-odds welcome deal with a longer qualifying window and the option of running a spread position, Spreadex offers something the other nine brands on this page do not. For a bettor who only wants fixed odds, the hybrid structure adds a product they do not need.

William Hill

William Hill’s welcome deal rotates with the season, and the headline that travels with it is shaped for accumulator bettors: the Football Acca Boost covers accas of two or more legs with each selection at 1/5 or bigger, with a boost from 3 per cent on a double up to 200 per cent on 20 or more legs, a maximum boost of £10,000 per online bet, and a run that runs until 30 May 2027. The acca boost is not a sign-up free bet in the £40-for-£20 mould; it is an ongoing enhancement on football accumulators for every customer, with the welcome offering structured around it.

What a customer gets on opening is the boost rather than a token, which means the headline is a percentage rather than a pound figure. The bettor does not place a £20 qualifying bet to release a £40 token; the bettor places accas at the floor of 1/5 per leg and earns the boost on the return. The licence is held by WHG (International) Limited under Commission account 39225, and the brand sits alongside 888 and other names under the same parent group.

For the acca bettor who stacks football slips already, the boost is worth more than a one-shot £40 token because it pays out repeatedly. For the single-bet customer, the boost adds nothing: the floor is too low and the customer does not stack enough legs to trigger the higher percentages. The book assumes a particular kind of bettor and rewards that bettor at the expense of everyone else.

Fitzdares

Fitzdares is the smallest name on this list by handle and the one with the tightest product. The welcome offer rotates; the standard arrangement is a free bet for a qualifying fixed-odds bet at minimum odds of 1/2, with the token issued in fixed denominations and used on the sportsbook. The payment stack is narrow but quick: Apple Pay, Mastercard and Visa, with Visa withdrawals usually same-day and Mastercard withdrawals taking up to 48 hours. A same-day withdrawal on a debit card is a competitive feature in a market where bank transfers can take two to three working days.

The licence is held by Fitzdares Limited under Commission account 400, one of the older account numbers on the Commission’s register. The brand’s profile is a high-end service book rather than a mass-market sportsbook: the betting menu runs deep on horse racing and on Premier League football, with thinner coverage of US sports and esports than the larger names.

For a bettor who values a same-day Visa withdrawal and a tighter, racier product, Fitzdares earns a look. For a bettor who wants the deepest in-play menu and the broadest market coverage, the brand is a smaller fish in a bigger pond.

Betboro

Betboro runs a 100 per cent matched free bet of up to £25 on the first qualifying wager, requiring a debit card deposit of at least £10 and a first bet of £5 to £25 with at least three selections each at 3/5 (1.60) or higher. The shape is a token rather than cash: a £25 first bet that loses returns a £25 free bet, with the free bet subject to the standard minimum-odds and expiry terms the operator applies. The £25 cap is below the £40 figure several of the larger names offer, but the qualifying stake range of £5 to £25 means a bettor with a small budget can clear the welcome without committing a £20 stake.

The licence is held by Webmedia Development N.V. under Commission account 44181, with the GB-licensed entity registered in Curaçao. The brand’s product sits in the medium-weight tier: in-play on the main European leagues, a bet builder on selected events, and a free-bet welcome rather than a cash bonus. The 1.60 minimum odds is at the gentle end of the market.

For a small-stake bettor who wants to clear a welcome without staking £20, Betboro’s £5-to-£25 range and 1.60 floor are the friendliest construction on this page. For a high-stake bettor, the £25 cap means the headline is below what the larger names offer, and the bet builder on selected events is shallower than bet365’s Bet Builder+ or Kwiff’s.

VBet

VBet’s sports welcome offer is a £10 free bet if a new, verified customer stakes £10 or more on a first-ever bet that loses. The framing is “risk-free” in the marketing; the substance is a refund-as-free-bet, with the £10 stake at risk on the first bet and the £10 token returned only if that bet loses. The token is a one-shot free bet that does not return its stake, expires on the operator’s standard window, and is restricted to fixed-odds markets.

VBet also covers a wide menu of sports and esports, with in-play markets on the major European leagues and a deeper esports product than most of the names on this page. The licence is held by SCGO Limited under Commission account 44662.

For a bettor who wants a small-stake welcome with a refund-as-token shape and a deeper esports product, VBet fits. For a bettor who wants the headline cash value of the free bet to exceed the qualifying stake, the offer’s £10-for-£10 is the smallest deal on this page.

BetGoodwin

BetGoodwin runs a “Bet £10 and Get £15 in Free Bets” welcome, made up of a £5 sports single, a £5 acca and a £5 Sub-Cover bet. The three tokens split the headline across three products, each with its own minimum-odds floor and its own expiry, and a customer who clears one token and lets the other two expire has effectively turned a £15 welcome into a £5 one. The Sub-Cover token is the unusual one — a refund on a single losing leg of an accumulator, applied to a specific BetGoodwin market — and it adds a small insurance product that the larger names do not run.

The licence is held by Goodwin Racing Limited under Commission account 2927, and the brand sits firmly in the racing-led book tier with a smaller football and in-play menu than the larger names.

For the racing-led bettor who likes to mix singles and accas, the three-token welcome rewards the customer who plans to use all three. For the customer who bets football exclusively, two of the three tokens are wasted.

Octobet

Octobet runs a 50 per cent back-as-free-bet up to £50, plus a £10 casino bonus for new customers. The headline is the 50 per cent match, capped at £50, which means a £100 first bet that loses returns a £50 free bet. The casino bonus on the side is the kind of mixed-product promo the Commission’s January 2026 rule has now banned from GB-licensed operators — the offer as published pre-dates the rule and is being wound down; the sportsbook welcome as it stands for new customers is the 50 per cent match.

The licence is held by Octopus Game Limited under Commission account 62545, and the brand runs a smaller product than the mass-market names: in-play on the major European leagues, a bet builder on selected events, and the sportsbook welcome as the main draw. The 50 per cent shape means the headline is half the qualifying stake rather than a multiple of it, and a £100 first bet that wins takes £200 of profit and pays nothing extra.

For a bettor who places large first bets and wants a half-back on a loss, the offer is reasonable. For a bettor who places small first bets, the £50 cap is unreachable and the headline is meaningless. The casino bonus, as noted, is on its way out under the new rule.

Betmaster

Betmaster is the lightest-touch welcome on this page: the brand does not advertise a fixed-odds sportsbook welcome offer in the same £40-for-£20 mould, and the welcome is a smaller free bet issued against a qualifying first bet at minimum odds of 1/2. The site is registered to BM Solutions GB Ltd, a Maltese company, under Commission account 65699. The product sits below the larger names: in-play on the major European leagues, a thinner market menu, and a smaller customer base.

The licence is the key fact. BM Solutions GB Ltd holds a Commission licence, the brand is on the public register, and the customer is inside GAMSTOP. The brand is not a mass-market name, and a customer comparing Betmaster against bet365 is comparing a thinner product on price rather than on menu.

For a bettor who values a smaller site with a Commission licence and is happy with a thin menu, Betmaster is a legitimate pick. For a bettor who wants in-play depth, a bet builder on every event and live streaming, Betmaster is not the right book.

DAZN Bet

DAZN Bet runs a standard free-bet welcome offer against a qualifying first bet, with Cash Out, a Bet Builder, daily bet boosts and in-play betting on the major European leagues. Cash Out availability is not guaranteed on every market, and bets stand if it is unavailable — the standard Commission-compliant framing. The site also offers deposit limits, loss limits and wagering limits as safer-gambling tools, with the limits set by the customer rather than imposed by the operator.

The licence is held by DZBT Limited under Commission account 48756, and the brand carries the DAZN media tie-in for streaming. The product is a newer build than the legacy names on this page, and the customer base is smaller than Coral’s or bet365’s.

For a bettor who wants a modern sportsbook tied to a streaming service and uses Cash Out heavily, DAZN Bet fits. For a bettor who wants the deepest racing product or the broadest international sports menu, the legacy names run deeper.

How to Read the Comparison

The table is a snapshot of what each operator’s own terms page states on the welcome subject. It is not a value ranking: the highest free-bet figure is not the cheapest offer once minimum odds, qualifying stake, expiry and whether the stake is returned are folded in. A £60 free bet at Spreadex for a £10 qualifying bet looks generous next to Coral’s £40 for £20, but the qualifying-bet window, the odds floor and the token’s expiry all move that comparison.

Worked Example: The Coral Welcome

The Coral welcome is the most common shape on this page, so it is the one worth doing the arithmetic on. The offer is £40 in free bets for a £20 qualifying sports bet at minimum odds of 2.00, with the £40 in free bets issued within seven days and expiring seven days after issue. The wagering cap of 10x applies to any bonus with a turnover requirement; the Coral welcome, as a free-bet offer without a turnover multiplier on the token itself, sits outside the cap.

The qualifying bet is the bettor’s first cost. A £20 bet at minimum odds of 2.00 returns £40 if it wins, with £20 of profit. The expected loss on a single £20 bet at minimum odds of 2.00 sits in the same range as the book’s margin — typically between 5 per cent and 8 per cent on a major-market 1X2 or match-result line, so the expected cost is roughly £1 to £1.60 on the £20. On a deeper market, a handicap or a totals line, the margin is wider and the expected loss is higher.

The £40 in free bets is the next cost. A free bet at odds of 3.00 wins £80 of profit and returns no stake; a free bet at odds of 2.00 wins £40 of profit and returns no stake. The bettor who places the £40 token at 2.00 doubles the headline to £80 total return but pays nothing on the stake — the £40 token is not refunded either way. The expected value of the £40 token, placed at any market the bettor chooses within seven days, depends on the margin of that market and the price the bettor takes. At a 5 per cent margin and decimal odds of 3.00, the expected value is roughly £40 × (3.00 − 1) ÷ 3.00 × 0.95, which works out to about £25 of expected return on the £40 token.

Add the two stages: a £20 qualifying bet with an expected loss of around £1 to £1.60, and a £40 token worth roughly £25 in expected return, and the net expected value of the Coral welcome is in the low-twenties. That is what the headline minus the arithmetic looks like.

The Commission cap of 10x would apply if Coral replaced the free-bet token with a £40 cash bonus at 10x, requiring £400 of qualifying bets before withdrawal. At the cap, the £40 bonus costs the bettor £400 of stake minus the £40 bonus itself, with an expected loss on the £400 of clearing turnover that depends on the margin of the markets the bettor uses. At a 5 per cent margin on a major-market line, the expected loss is roughly £20 on the £400, leaving £20 of bonus value against £20 of clearing cost — a wash, before the bettor’s time and the seven-day window are counted.

Reading the Offers

Three patterns show up across the ten brands.

The first is the fixed-token welcome: Coral, Unibet and several others issue a fixed free-bet value for a fixed qualifying stake, with the token expiring fast. The bettor’s decision is which market to place the token on inside the window.

The second is the refund-as-token welcome: VBet, Octobet and others return a losing first bet as a free bet rather than cash. The bettor’s first bet is at risk, and the token is single-use. The marketing framing is misleading: “risk-free” applies only if the first bet loses, and the refund is in tokens rather than money.

The third is the enhancement welcome: William Hill’s acca boost is the clearest example — no token, no qualifying stake, but a recurring percentage boost on the customer’s own accumulator bets. The bettor who plays accas already earns the boost; the bettor who does not sees nothing.

The bettor who values certainty prefers the fixed-token welcome with a long qualifying window. Spreadex’s 28-day window is the longest on this page. The bettor who values a refund on a first bet prefers the refund-as-token welcome, with the understanding that the refund is in tokens, not money. The bettor who plays accas prefers the enhancement welcome, with the understanding that the boost applies only to accas, not to singles.

The Cheapest Offer on This Page

The cheapest welcome, by expected value, is the offer with the longest qualifying window, the lowest minimum odds, the shortest expiry on the token, and the highest token-to-qualifying-stake ratio. Spreadex’s £60-for-£10 at 1/2 has the longest qualifying window (28 days), the lowest minimum odds (1/2) and the highest ratio (6:1). The token’s expiry window sits at the operator’s standard 7 days, and the token is paid in fixed denominations the bettor can place on a single bet each.

Coral’s £40-for-£20 at 2.00 has a 7-day qualifying window, the market’s standard 2.00 floor and a 2:1 ratio. The shorter qualifying window is the cost; the lower minimum odds on Spreadex is the saving.

Betboro’s 100 per cent match up to £25 has a £5-to-25 qualifying range, a 1.60 minimum odds and a 1:1 ratio at the cap. The cost is the smaller token; the saving is the lower stake range and the lower minimum odds.

The cheapest welcome for any particular bettor is the one that matches that bettor’s stake size, market preferences and time horizon. A £5 bettor who plays accas at 1.60 gets more from Betboro than from Coral; a £20 bettor who plays singles at 2.00 gets more from Coral than from Betboro.

The Bonus Turnover Calculation

A £20 cash bonus at 10x wagering, the structure the Commission’s January 2026 rule now caps at, requires £200 of qualifying bets before the bonus and any winnings withdraw. At a £5 stake per bet, that is forty bets at minimum odds of 2.00 inside the bonus window. At a £10 stake, it is twenty bets. The bettor who stakes the £200 on singles at 2.00 with a 5 per cent margin carries an expected loss of about £10 across the clearing turnover — half the £20 bonus value, before the bettor’s time and the bonus expiry window are counted.

At higher minimum odds, the bettor can run fewer bets at higher stakes. At lower minimum odds, the bettor can run more bets at lower stakes, with the same £200 turnover. The Commission’s cap does not change the math; it changes the upper bound on what a bonus can demand. Above 10x, the bonus would be illegal at a GB-licensed site; below 10x, the bonus’s value depends on the bettor’s stake size, the market margin and the bonus window.

The expected cost of clearing a bonus, stated as a band rather than a figure, runs from about 30 per cent of the bonus value at a low market margin and a long bonus window to about 60 per cent at a high market margin and a short window. A £20 bonus cleared at 5 per cent margin over 30 days costs the bettor about £6 of expected loss on the turnover, leaving £14 of net bonus value. The same bonus cleared at 8 per cent margin over seven days costs about £11, leaving £9.

Wagering Requirements and the Commission’s Other Rules

Beyond the 10x ceiling, the Commission’s promotion rules since 19 January 2026 ban mixed-product promotions: an offer that asks the bettor to wager on betting and casino, or on betting and bingo, in exchange for one reward. The Octobet welcome as published runs alongside a £10 casino bonus, and that mix is the kind of construction the rule has banned; the operator is winding the casino side down for new customers.

The Commission has also announced, in a staged plan published on 7 July 2026, that financial risk assessments — the affordability checks that have been in the press under that name — will apply at higher net-deposit thresholds, with no start date. The earlier financial vulnerability check, in force since 30 August 2024 and applying at £150 of net deposits in a rolling 30 days since 28 February 2025, is a public-record check, not an income or credit check. A bettor crossing the £150 threshold should expect a public-record check at the licensed operator of choice; a bettor below the threshold should not.

Deposit limits are a separate lever. Operators must offer a gross deposit limit on a fixed time frame, with the first phase applying since 31 October 2025 and a second phase postponed to 30 September 2026. The live status of the second phase is not established. There is no state-set ceiling: limits are the customer’s own choice, and a tighter cap is the cheapest form of safer gambling available.

Player Protection Beyond the Welcome

Every brand reviewed here is on GAMSTOP, and a customer who has self-excluded through GAMSTOP cannot open an account. The minimum exclusion is six months; the maximum is five years with auto-renewal. After the minimum period the customer can ask GAMSTOP to remove the exclusion, and a further seven years’ protection runs on top of the chosen period.

Identity verification is the first step at every licensed operator. Name, address and date of birth are verified before the first deposit, including for a free bet or bonus, and the verification uses public sources rather than a credit check. A bettor who has moved address or changed name should have the relevant documents ready — a utility bill, a bank statement, a passport — and a bettor who shares an address with a self-excluded partner should be ready to demonstrate independent identity.

Help is reachable through GamCare and the National Gambling Helpline, through GambleAware, through NHS gambling clinics for face-to-face support, and through Gamblers Anonymous for peer-led meetings. A bettor who has set a deposit limit and feels the limit slipping has, at every licensed operator, the route to a self-exclusion that closes the account.

The Offshore Caveat

A GB licence is compulsory at the point of consumption. An operator whose remote facilities are used in Great Britain needs a Commission licence whether the operator is based in Gibraltar, Malta or Curaçao. Several of the brands reviewed here are registered outside the UK — Webmedia Development N.V. is Curaçao-registered, BM Solutions GB Ltd is Maltese, Platinum Gaming Limited (Unibet’s UK side) is in Gibraltar — and a GB licence is what makes that offshore base legal for GB customers.

A brand without a GB licence is not legal for GB customers to use. The Commission has cease-and-desist powers, search-engine referrals, and relationships with registrars, hosts and payment providers. Court-order DNS blocking powers are being granted or are imminent. None of that reaches the customer who bets on an unlicensed site: there is no offence aimed at the customer who bets on an unlicensed site, only at the operator that offers one.

The customer’s loss is the protection. No GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld, no 10x bonus cap, no £150 vulnerability check. The Commission’s £150 vulnerability check, the GAMSTOP enrolment and the 10x bonus cap all stop at the GB-licensed boundary, and an unlicensed site has no incentive to copy them.

Tax and What the Bettor Pays

The bettor pays no tax on betting winnings in Great Britain. The operator pays General Betting Duty on gross profits, currently 15 per cent on remote bets. From 1 April 2027 a new remote betting rate of 25 per cent applies within General Betting Duty, while remote bets on UK horse racing, bets on self-service betting terminals in licensed premises, pool betting and in-person betting stay at 15 per cent. Whether operators pass duty on through tighter odds is not established.

Spread betting has its own rates: 3 per cent financial and 10 per cent other. The player’s tax position on a financial spread bet is different from the position on a fixed-odds sportsbook bet, and a bettor running both sides of Spreadex’s book is paying different duty on each. The Commission’s statutory levy is a separate charge, not a tax.

What This Page Does Not Cover

This page covers UK-licensed welcome offers for fixed-odds sports betting. It does not cover casino welcome offers, poker welcome offers, or the betting-exchange welcome offers from a separate licensee. It does not cover price boosts and acca insurances that run as ongoing promotions rather than welcome deals. It does not cover the spread betting product at Spreadex in any detail beyond noting its presence and its regulator.

It does not name the offshore operators that have advertised to UK customers without a GB licence, because the public register is the test of whether a brand holds a licence and the page’s angle is licensed offers. A bettor who wants the offshore market has other guides.

It does not predict outcomes. No welcome offer turns into a winning strategy, and no system converts a £20 qualifying bet into a £40 free bet with no risk. The math above shows what each offer costs the bettor in expected terms; the math is a band, not a guarantee, and the bettor’s actual outcome will fall above or below it on any single welcome.

Frequently asked questions

How do you claim a betting welcome offer?

Open an account with the operator, complete identity verification, opt in to the welcome promotion on the promotions page or the bet slip, make the qualifying deposit by an eligible method (usually a debit card or instant bank transfer), and place the qualifying bet at the minimum odds stated in the offer. The free bet is credited within the operator’s stated window — typically within a few hours of the qualifying bet settling, occasionally inside 48 hours — and expires on the window the terms state.

Which betting site offers a welcome bonus?

Every UK-licensed bookmaker reviewed on this page offers a welcome bonus, and every GB-licensed operator is on the Gambling Commission’s public register. Coral, Unibet, Spreadex, William Hill, Fitzdares, Betboro, VBet, BetGoodwin, Octobet, Betmaster and DAZN Bet each run a fixed-odds welcome offer as their own terms describe. The Commission’s public register is searchable by business name, trading name, domain or account number and is the authoritative list.

Which betting site has the best welcome bonus?

The cheapest welcome depends on the bettor’s stake size, market preferences and time horizon. Spreadex’s £60-for-£10 at minimum odds of 1/2 has the longest qualifying window (28 days) and the lowest minimum odds on this page; Coral’s £40-for-£20 at minimum odds of 2.00 has the standard 7-day window and the market’s typical 2.00 floor; Betboro’s 100 per cent match up to £25 has the smallest stake range and the gentlest 1.60 floor. The “best” is whichever offer the bettor will actually clear inside the window.

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 10x. A £10 bonus at 50x would have demanded £500 of qualifying bets; under the cap, no more than £100. Mixed-product promotions — an offer that asks the bettor to wager on two or more product types in exchange for one reward — are banned under the same rule. Whether the cap applies to free bets with no wagering condition is not established; free bets without a turnover multiplier, the standard welcome shape in the UK, sit outside the cap.

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

Minimum odds are the floor below which a bet does not count toward the wagering requirement. A welcome offer with a 2.00 (1/1) floor demands that every qualifying bet be at 2.00 or higher; a bet at 1.80 does not count. The wagering requirement is the multiple of the bonus (or the bonus plus deposit) that must be staked in qualifying bets before any winnings withdraw. A £20 bonus at 10x means £200 of qualifying bets at or above the minimum odds; a £20 bonus at 5x means £100. The Commission’s 10x cap is the upper bound on the second figure at a GB-licensed site.

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

A free bet is a token that pays only the profit on a winning bet, not the stake. The token is the bettor’s stake, supplied by the operator; returning it as well would mean paying the stake twice. A £10 free bet at odds of 3.00 wins £20 of profit — the £30 return minus the £10 token — and the token is consumed whether the bet wins or loses. The closer to evens the free bet is placed, the more the stake-not-returned rule costs the bettor. At odds of 2.00 the bet pays £10 of profit on a £10 token, halving the headline odds; at odds of 5.00 the bet pays £40 of profit on the same £10 token, with the effective price closer to the decimal odds.
