A sign-up offer is the cheapest way a bookmaker learns whether you are worth keeping. The “free” bit is rarely the giveaway it sounds; the costly bit sits behind it, in turnover rules, minimum odds, expiry clocks and the small print that decides whether the bonus ever turns into withdrawable cash. This page costs ten of them against each other, and against the promotion rules that have governed Great Britain since 19 January 2026.

Verified against the Gambling Commission’s public register on October 30, 2026.

What a “sign-up offer” actually is

A sign-up offer is a promotion attached to opening a new account and placing a first qualifying bet. The headline number is usually the size of a free bet you receive after that first bet settles; sometimes it is a matched deposit bonus or a “bet and get” credit. The headline is the smallest part of the offer. Three other numbers do almost all the work:

• the qualifying bet: how much you stake, at what minimum odds, in which market, to unlock anything at all;
• the wagering requirement: how many times the bonus (or sometimes the bonus plus deposit) must be turned over before winnings become withdrawable;
• the expiry window: the days you have to do it in.

A fourth condition is almost universal and almost never written as loudly: the stake of a free bet is not paid back with the winnings. A winning £10 free bet at 3/1 returns £40, not £50. That is why a free bet is worth less than its face value, and why bookmakers love them as a “welcome gift”.

Two technical distinctions matter here. A cash bonus adds money to your balance and is usually withdrawable once the turnover rule is satisfied. A free bet is a token whose stake is forfeit if it wins; only the profit lands. The Commission treats the two very differently, and so should a punter comparing offers.

The 10x rule since 19 January 2026

The Gambling Commission’s new promotion rules came into force on 19 January 2026. They changed what UK bookmakers may legally put in front of a customer:

• Wagering requirements on bonuses are capped at 10x. A £10 bonus with a 50x turnover rule (which used to be standard) would have needed £500 of bets to release the winnings. Under the cap, no more than £100 of qualifying bets can be required before any part of the bonus becomes withdrawable. The cap applies to the wagering requirement attached to a bonus, not to a free bet that carries no such condition (that point is not settled in the published rules).
• Mixed-product promotions are banned. An offer that asks a customer to gamble on two or more product types — for example “bet £10 on football to claim 50 free spins” — is no longer permitted. A betting welcome offer must be a betting welcome offer. It cannot drag you into a casino lobby.

These rules do not cap the size of a bonus, the minimum odds of a qualifying bet, the expiry window, or the value of a free bet. They cap how much betting the bonus can demand of you, and they cap the cross-sell. Everything else is the bookmaker’s choice.

A worked costing: Coral’s “bet £20, get £40”

Take a representative example from the figures this page draws on: Coral’s sports welcome offer for new GB customers. It works like this. Place £20 on any sports market at minimum odds of 2.0 (1/1). If the bet settles (win or lose; the rule only cares that a qualifying bet was placed), Coral credits £40 in free bets within seven days. The free bets expire seven days after issue.

The headline reads as a £20-for-£40 deal. Costed, it is a £20 risk for up to £40 of free bet value, where the value of a free bet is its stake times (odds minus 1) divided by the odds, times the payout share of the market you spend it on. At evens (2.0), a £20 free bet is worth roughly £10 in expected terms — half its face. Across the £40 credit, the expected realised value is closer to £20 than to £40. The “free” gift is in fact a token whose expected worth sits below its label.

That is the shape every offer on this page has, with the wagering cap now bounding how much further the bookmaker can ask the customer to play.

The costing arithmetic, in plain prose

What follows is the information-gain calculation this page is built around. It uses the bonus-turnover formula: required turnover equals the bonus base times the wagering factor (the base is the bonus itself, or the bonus plus the deposit, depending on which one the operator names); bets needed equals that turnover divided by the average stake per bet; only bets at or above the minimum price count; and the expected cost of clearing the offer equals the required turnover times the margin of the market you are asked to play in.

Taking Coral’s £40 free-bet credit and treating it as if it carried a notional 10x wagering requirement (it does not, but a similar bonus in the same shape could): the bonus base is £40, the wagering factor is 10, so the required turnover sits at £400 of qualifying bets. At a £10 stake per bet, that is forty bets. If those bets go into a market with a typical 5% margin (the bookmaker keeps 5% of every unit bet on it), the expected cost of clearing the offer is £20 — £400 times 5%. The £40 credit is therefore paid for in roughly £20 of margin, before any account of the qualifying £20 stake and the opportunity cost of seven days of betting.

State the result as a band rather than a single number: between one and two full stake-equivalents, depending on which market you play in and what the qualifying stake demands. The point is not the precise figure; it is that the bonus is not the gift it reads as, and the wagering cap is the rule that decides how much further the cost could go. Under the old 50x regime the same offer could have eaten five times more.

How the ranking on this page is built

Ten bookmakers sit in the comparison below, ordered by the offer that gives the new customer the most withdrawable value for the smallest commitment. The first criterion is whether an offer is structured as a free bet with no wagering requirement, or as a bonus with one. Where two offers are tied on that, the second criterion is the minimum odds of the qualifying bet (the lower the threshold, the easier to find a market to place it on), then the expiry window, then the size of the headline credit.

This is not a ranking of bookmakers as products. A licence is a licence and a brand is a brand; the gambling business differentiates on welcome offers and on whether you can find a market you actually want to bet on once the offer is done. Two readers can read this page and reach different verdicts about the same offer: one wants the lowest possible commitment; the other wants the largest credit and is happy to play for it. The ranking is built so the trade-off is visible.

The comparison at a glance

Columns carry only what each operator’s own terms state on the welcome offer and the relevant Commission account. Cells without a published headline sign-up credit in the listings reflect the absence of one, not a missing number.

What UK law says about these offers

The regulator is the Gambling Commission, a non-departmental public body sponsored by the Department for Culture, Media and Sport. It licenses the entire commercial market under the Gambling Act 2005, which covers Great Britain (England, Scotland and Wales); Northern Ireland sits outside the Act and has its own older law, which is why every reference here is to a “GB licence” rather than a “UK licence”.

Since the Gambling (Licensing and Advertising) Act 2014, an operator whose remote facilities are used in Great Britain needs a Commission licence wherever it is based. A Curaçao, Maltese or Gibraltar licence is not a substitute for a GB one; it may sit alongside, but the point-of-consumption rule makes a GB licence compulsory for any brand accepting GB customers. The Commission’s public register can be searched by business name, trading name, domain or account number, and that register is the whole test of whether a brand holds a licence. Brands use both extensions (.com and .co.uk), so the domain itself proves nothing.

Identity and age

Identity is verified before a customer can deposit or gamble at a GB-licensed site, including for a free bet or a bonus. Name, address and date of birth are checked; the requirement has been in force since 7 May 2019. Minimum age is 18. There is no anonymous play at a licensed operator, and that is the price of the rest of the regime: GAMSTOP coverage, the bonus cap, the dispute-resolution route and the fund-protection rules come as a single package.

Financial spread betting sits outside the Commission’s remit

Spreadex is an interesting case in this comparison, because it runs two parallel products: fixed-odds sports betting, which the Commission regulates, and financial spread betting, which the Financial Conduct Authority regulates. Spreadex’s own homepage makes the distinction plain — losses on spread bets can exceed the deposit you placed — and the two licences are administered by different bodies with different consumer protections. A bettor looking at the brand needs to know which product they are entering. A fixed-odds free bet is one thing; a spread bet is another kind of risk entirely.

What the bonus cap does and does not bind

The 10x wagering cap is the most consequential change for this page. To repeat the point, in the language the rule uses: a £10 bonus with a 50x turnover rule would have meant £500 of qualifying bets. Under the cap, the maximum wagering requirement any operator may attach to a betting bonus is 10x the bonus base (the bonus itself, or the bonus plus the deposit, depending on which one the operator names). Free bets that carry no wagering condition are a separate question on which the published rules are not settled. Minimum odds of qualifying bets, expiry windows, the size of a bonus and the headline value of a free bet are all untouched by the cap; they remain the operator’s choice.

The mixed-product ban is the other half of the same reform. A betting welcome offer that requires you to play a casino game to release the betting bonus is no longer permitted. The rule cuts the cross-sell that used to ride alongside most sports offers.

Tax, briefly

The player pays no tax on betting winnings in Great Britain. General Betting Duty is the operator’s tax on its gross profit from betting, currently 15%, and a new remote rate of 25% applies within it from 1 April 2027; the rate on bets on UK horse racing, on bets placed through self-service terminals in licensed premises, on pool betting and on in-person betting stays at 15%. The duty is the operator’s liability, not yours; whether operators pass it on through tighter odds is not established in any published source. A professional gambler should ask HMRC or an adviser; for everyone else, the line is “no player tax on winnings” and that is enough.

What “offshore” means when a customer meets it

A GB-licensed site binds itself to all of the above. An unlicensed site, by definition, does not. The framing of that gap is honest on both sides: licensed means checks, limits, GAMSTOP coverage, the bonus cap and a British dispute-resolution route, and also identity verification before the first bet; unlicensed means none of those protections and the loss of recourse if the operator withholds funds. Saying an unlicensed site is “the safe choice” is not a conclusion available from the facts; saying it is “the unregulated choice” is. Enforcement against unlicensed operators is disruption rather than blocking — cease-and-desist notices, search-engine referrals, work with registrars and payment providers, and court-order DNS blocking powers the Commission has been given or is about to receive. No ISP blocking regime is in operation. Nothing in this section tells a reader that an unlicensed site is illegal to use; it tells the reader what protection is missing.

Responsible gambling: the part the offer can swallow

A welcome offer is the moment a bookmaker’s customer-protection machinery starts working on a new account, and a reader should know how that machinery is set up before any “free” credit is accepted.

GAMSTOP

GAMSTOP is the national multi-operator self-exclusion scheme and a mandatory licence condition for online operators since 31 March 2020. The exclusion periods are six months, one year, five years, or 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 betting-shop exclusion scheme is separate. If a self-exclusion is in place, a sign-up offer is not available by definition: the registration will be refused.

Affordability and vulnerability checks

The Commission’s financial vulnerability check has been in force since 30 August 2024 and applies to licensed remote betting when a customer’s deposits minus withdrawals exceed £150 in a rolling 30 days (the threshold has applied since 28 February 2025). It is a public-record check — bankruptcy, county court judgments and the like — not an income check and not a credit reference check. A wider “financial risk assessment” regime has been announced in a staged plan (the Commission’s article of 7 July 2026); the plan has no start date. The honest reading is “announced, staged, no start date” — never “in force”.

Deposit limits

Operators must offer a gross deposit limit on a fixed time frame. A first phase has applied since 31 October 2025; a second phase was postponed to 30 September 2026, and whether that second phase is now live is not established in any published source. There is no state-set deposit or loss ceiling for betting. The limits are the customer’s choice. DAZN Bet’s help pages, as one example, list deposit, loss and wagering limits among the safer-gambling tools available on a licensed account; most of the operators in this comparison offer the same tools under different names.

Help and counselling

GamCare runs the National Gambling Helpline. GambleAware funds treatment and education. The NHS runs regional gambling clinics. Gamblers Anonymous runs peer-support meetings. These services are free, confidential and outside the bookmaker’s relationship with the customer; the relationship ends at the safer-gambling tools.

Credit cards are out

Credit cards are banned for gambling in Great Britain (since 14 April 2020), including credit-card-funded payments through an e-wallet. Debit cards and bank-based payments are not covered by the ban. A welcome offer that asks for a credit card is asking for a payment method the regulator does not allow; ignore it. Most sign-up offers require a debit card or instant bank transfer to qualify.

Operator reviews: what each welcome offer costs and who it suits

The reviews below cover every brand the comparison table names, in the order the table sets. Each write-up closes on a verdict that takes a position, not a description of the offer.

LiveScore Bet

LiveScore Bet takes payments by Visa, Mastercard, Apple Pay, PayPal, Pay by Bank (Open Banking) and Revolut Pay — a deliberately broad set, with two of the methods (Open Banking and a card) covering the typical qualifying-bet requirement. The welcome offer is structured around free bets credited once a qualifying bet settles; the Commission licence is held under account 56859 by LiveScore Betting and Gaming (Gibraltar) Limited.

The breadth of the payment set matters because most sign-up offers require a debit card or instant bank transfer to qualify, and LiveScore Bet has both. The free-bet structure means the offer’s real cost is the value the free bets realise once spent, not the headline credit. A reader looking for a brand that does not force a switch of payment method for the welcome offer has found one.

Verdict. The cleanest onboarding of the comparison for a customer who already pays with Apple Pay or Open Banking. The free-bet credit is modest; the friction is low.

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 shape is “lose, and the bet is refunded as a free bet”. It is not a “risk-free” bet in the sense the marketing word wants to imply; it is a free bet credited only on a losing qualifying bet, and the stake of the free bet is not paid back with any win. The licence is held under Commission account 44662 by SCGO Limited.

The interest of the shape is in the symmetry: you stake £10 to win nothing on the offer itself, and if the bet loses you get a £10 token to use once. The expected value of a £10 free bet at evens is roughly £5; the qualifying bet’s stake is the cost of entry. There is no second-stage turnover requirement on the free bet in the listing.

Verdict. A small, clearly priced offer for a customer who wants to test the brand with minimal commitment. The cost is the £10 stake, and the ceiling is the £10 free bet’s expected value. Best read as a low-risk first visit, not as a profit centre.

Betmaster

Betmaster is operated by BM Solutions GB Ltd, registered in Malta, and holds Commission account 65699. The home page does not state a headline sign-up credit, so the comparison describes what is known about the brand and leaves the offer blank rather than invent one. A reader interested in Betmaster should check the operator’s own terms before registering, because what is on offer changes frequently.

The Maltese company structure is a feature, not a flag. Many GB-licensed brands operate through a Maltese or Gibraltar parent, and a Commission account is the only test that matters. BM Solutions GB Ltd holds one, and the register says so.

Verdict. A brand for a customer who already has an account there, or who values the operator’s market range over the size of its sign-up credit. The comparison cannot speak to the current offer without the operator’s own terms in hand.

Geoff Banks

Geoff Banks’ app is published by GB Sports Advisors Ltd and offers live in-play prices and ante-post prices on future events. The licence is held under Commission account 54095 by GB Sports Advisors Limited. No headline sign-up credit is listed.

Ante-post and in-play are the brand’s two distinguishing features; the comparison does not have a welcome offer to set against the rest. A reader looking for a price-driven bookmaker with deep in-play markets has found one; a reader looking for the largest welcome credit has not.

Verdict. A specialist brand for a customer whose betting is in-play and futures. The welcome credit is not the point; the market depth is.

Coral

Coral’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 of 2.0 (1/1), with £40 in free bets issued within seven days and expiring seven days after issue. The qualification requires a debit card or instant bank transfer; the listed payment set includes Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly. The licence is held under Commission account 54743 by LC International Limited — the same licensee that runs Ladbrokes, which is why the two brands are never presented as independent operators.

The offer is the largest headline credit in the comparison that requires a debit card or instant bank transfer to qualify. The cost is the £20 qualifying stake and the seven-day expiry on the free bets. Coral runs a daily free Reward Shaker, an Odds Booster on hundreds of markets and free-to-play games including Football Super Series with a £10,000 jackpot; these are useful if the welcome credit is spent, less so before.

Verdict. The best-value headline credit in the comparison for a customer happy to qualify with a debit card or instant bank transfer. The seven-day expiry is the constraint; spend the free bets early, in markets you already follow.

Smarkets (SBK)

Smarkets also runs the SBK sportsbook, whose UK welcome offer is a £20 first deposit and a £20 bet at minimum odds of 3.0 for £60 in free bets within 48 hours. The licence is held under Commission account 39173 by Smarkets (Malta) Limited, and the category is remote betting intermediary — the licence type for betting exchanges. The offer comes with Cash Out, Bet Builder and live horse racing streams.

A 3.0 (2/1) minimum on the qualifying bet is the second-strictest threshold in this comparison and the highest credit-to-stake ratio. The expected value of the £60 free-bet credit at typical markets is around £30, paid for by the £20 qualifying stake and the difficulty of finding a 3.0 selection you actually want. The 48-hour window for credit issue is unusually fast.

Verdict. The best headline credit in the comparison for a customer who can find a 3.0 selection they want to bet on anyway. The minimum odds is the constraint; do not chase the credit with a bet you would not otherwise place.

bet365

bet365 offers Bet Builder+ (combining 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. The licence is held under Commission account 55148 by Hillside (UK Sports) ENC. The source listings do not state a headline sign-up credit, which means the comparison describes the brand’s feature set rather than a specific welcome offer.

Bet Builder+ is the brand’s distinguishing feature, and the Super Boosts and Winnings Boosts layers are the part of the offer a returning customer uses most. A new customer opening an account to claim a welcome offer has to take what the operator’s terms page says at the moment of registration, not what a comparison page can quote.

Verdict. A brand for a customer whose interest is the Bet Builder+ product and the daily boosts, not the size of a one-off credit. Check the current welcome offer on the operator’s own page before registering.

Kwiff

Kwiff’s Supercharge feature can instantly boost the odds on a bet, for example from 2/1 to 20/1, and it can apply to single or multi bets on any sport. The brand also offers Bet Builder and Bet Builder+ (combining Bet Builder bets from different games) and a guaranteed weekend acca boost. The licence is held under Commission account 44448 by Eaton Gate Gaming Limited.

The Supercharge feature is the comparison’s only surprise mechanic: a stake at 2/1 can land at 20/1 if Kwiff elects to boost it. The selection is not the customer’s; the boost is. That distinction makes Supercharge a different kind of product from a price boost, and the expected value of a boosted bet depends on how often Kwiff chooses to boost. No headline sign-up credit is listed.

Verdict. A brand for a customer who values a novel odds mechanic over a fixed welcome credit. The Supercharge feature is the headline; the welcome offer is whatever the operator’s terms page says today.

BetGoodwin

BetGoodwin’s sports welcome offer 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 licence is held under Commission account 2927 by Goodwin Racing Limited — by some margin the lowest account number in this comparison and one of the oldest Commission registrations still active.

The split into three tokens is the interesting feature: a £5 single, a £5 acca and a £5 Sub-Cover bet. The Sub-Cover name is the operator’s own and refers to a market on substitutes scoring, which is the kind of niche product a long-established bookmaker carries. The total credit is modest; the variety of tokens is wider than the credit.

Verdict. The lowest-commitment welcome offer in the comparison for a customer who wants to try the brand with three small bets rather than one larger one. The Sub-Cover bet is the differentiator.

NetBet

NetBet Sport offers Daily Boosts, Profit Boosts and free-bet offers, a Bet Builder with instant dynamic odds, and sports stats for major leagues. The licence is held under Commission account 39170 by Netbet Enterprises Limited.

Daily Boosts and Profit Boosts are the everyday feature set, and a Bet Builder with instant dynamic odds is the product differentiator. A reader looking for a specific welcome offer should check the operator’s own terms page at the moment of registration. The market stats layer is a quiet feature that helps when the welcome credit is spent and the customer is back to the regular menu.

Verdict. A brand for a customer who values daily boosts and a dynamic Bet Builder over a one-off welcome credit. Check the current welcome offer on the operator’s own page before registering.

How the offers stack against each other

Step back from the individual write-ups and the shape of the market is plain. The largest headline credit in the comparison belongs to Coral (£40) and Smarkets / SBK (£60). The lowest qualifying stake is shared by BetGoodwin (£10) and VBet (£10). The strictest minimum odds belongs to Smarkets (3.0), with Coral next (2.0). The most generous expiry is not really generous anywhere — seven days is the norm, with Smarkets’ 48-hour credit issue the only outlier (and in the right direction: faster credit means more time to spend it).

Five of the ten operators — Betmaster, Geoff Banks, bet365, Kwiff and NetBet — are distinguished by their feature set rather than a headline welcome offer. For a customer whose priority is the size of the credit, the comparison narrows to five. For a customer whose priority is the product beyond the welcome credit, the comparison widens.

The wagering cap is the silent constant across all of them. None of the offers in this comparison carries a published 50x or even 20x turnover rule, because none of them is allowed to under the post-19 January 2026 regime. The largest requirement any of them could carry on a betting bonus is 10x the bonus base. That is the most important fact on this page, and the one that separates a 2026 comparison from one written a year earlier.

What a reader should do before claiming

Three checks belong in the customer’s hands, because no comparison page can make them for you.

Check the licence. The Commission’s public register lets you search by brand, domain or account number. The ten operators on this page are all on it; the account numbers in the comparison table above are the search terms. If a brand is not on the register, the rest of this page does not apply.

Read the qualifying bet. Minimum odds, minimum stake, eligible markets and eligible payment methods are stated in each operator’s own terms. A free bet that requires a 3.0 qualifying selection is not the same as one that requires 2.0; a credit card does not qualify at most GB sites, and the offer may be void if the deposit comes through a method the terms exclude.

Read the turnover and the expiry. If the offer carries a turnover rule, check the wagering factor, the base (bonus, or bonus plus deposit), the minimum odds of those bets and the time limit. If the offer is a free bet with no turnover rule, check the expiry, the eligible markets and the maximum odds. The numbers are not hidden, but they are not on the marketing page either.

Frequently Asked Questions

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

Choose a brand licensed by the Gambling Commission and check its account number on the Commission’s public register. Open the account, verify your name, address and date of birth (the regulator requires it before any deposit), choose a payment method from the operator’s list (credit cards are banned for gambling), make the qualifying deposit and bet required for the welcome offer, and wait for the credit to land. The whole process takes a few minutes for the registration and up to a week for the credit.

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

Since 19 January 2026 the cap is 10x the bonus base — the bonus itself, or the bonus plus the deposit, depending on which one the operator names. A £10 bonus with a 50x turnover rule would have needed £500 of qualifying bets; under the cap, no more than £100 of qualifying bets can be required before any part of the bonus becomes withdrawable. The cap applies to bonuses, not to free bets with no wagering condition; that point is not settled in the published rules.

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

Minimum odds is the shortest price at which a bet qualifies for the offer or for clearing a turnover requirement — for example, 2.0 (1/1) means the bet must be at evens or longer. Wagering requirement is the multiple of the bonus base that must be staked in qualifying bets before winnings become withdrawable; under the cap it cannot exceed 10x for a betting bonus.

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

Because that is how a free bet is defined. A £10 free bet at 3/1 returns £40 if it wins: £30 of profit plus the £10 stake in winnings. The £10 stake is not returned because it was never the customer’s money to begin with. That is why a free bet is worth less than its face value, and why bookmakers love them as a “welcome gift”. The expected value of a £10 free bet at evens is roughly £5.

Can a sports betting bonus be tied to a casino bonus under the current rules?

No. Since 19 January 2026, mixed-product promotions are banned: an offer that requires gambling on two or more product types — for example “bet £10 to claim 50 free spins” — is no longer permitted. A betting welcome offer must be a betting welcome offer, and it cannot drag you into a casino lobby, bingo product or lottery to release its bonus.

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

Go to the Commission’s public register and search by the brand’s trading name, its operating company’s name, its domain or its account number. The account numbers for the ten brands in this comparison are listed in the table above. If a brand does not appear on the register, the brand is not licensed to take GB customers, and the protections on this page do not apply.
