Current as of 27 October 2026 and checked against the Gambling Commission’s public register.

A welcome offer is the headline a bookmaker uses to win a new account. The figure on the billboard is rarely the figure in the punter’s pocket. Underneath every “Get £40 in free bets” sits a set of mechanics — a minimum price, an expiry, a stake that may or may not come back, and since 19 January 2026 a 10x ceiling on the wagering a bookmaker is allowed to demand in return. The point of this page is to lay those mechanics out, side by side, for ten operators that hold a Gambling Commission remote licence, and to let the reader see which path fits which kind of punter.

The shortlist below is the set the Gambling Commission has issued with a remote general betting standard (real events) licence to a Great Britain-facing site, and the order is the order on the Commission’s public register — not a ranking. Every entry names what the offer really is, what it costs the reader, and where the brand’s own terms sit on the line between generous and ordinary. The single calculation that runs through the page belongs to the kind of bonus that asks a punter to roll the money over many times, because that is where a “free” offer can quietly become the most expensive bet on the slip.

The shortlist at a glance

The table is a map, not a verdict. Reading the rows in sequence does not put the best offer at the top. The reading that matters is which column a punter cares about — the licence line, the bonus structure, the friction around qualifying, the speed of a withdrawal once the offer is cleared. Each of those is a different door into the same shortlist, and each is taken up further down the page.

Why the 10x cap matters more than the headline number

On 19 January 2026 the Gambling Commission brought new promotion rules into force. The headline change for anyone comparing welcome offers is a 10x ceiling on wagering requirements. In plain terms, if a bookmaker hands a customer a £10 bonus, the most that bookmaker may now ask for in return is £100 of qualifying bets before the bonus is withdrawable. Before the cap a £10 bonus could come with a 50x requirement — £500 of bets to clear it. That is a fivefold cut in the turnover a bonus can demand.

The second change is harder to spot in any one offer but matters in the long run. Mixed-product promotions — the kind that say “bet on football to get free spins” or “deposit for sports and casino credit at once” — are banned outright. A bookmaker cannot require a sports punter to play through bonus money in a casino, a bingo room or a lottery product to clear the offer. The two changes together reshape the floor under every welcome offer on a British-licensed site: less friction to clear, fewer cross-product traps, and a smaller gap between the headline and what the offer actually delivers.

What the rules do not do is fix the structure of the typical sports welcome offer, which is still a free bet rather than a cash bonus. A free bet is what most of this shortlist is built on, and the difference is the one most readers miss: the stake of a free bet is not returned with the winnings. Place a £10 free bet at 5.0 and a winning bet returns £40, not £50. The £10 is the bookmaker’s contribution, and it is spent the moment the bet is placed. That single rule is why a “£40 free bet” headline on one site can be worth less than a smaller offer on another where the qualifying odds or the expiry are kinder.

How a welcome offer is really built

Three pieces sit under any sign-up offer on a British-licensed sportsbook, and the differences between operators come down to how each piece is set.

The first is the qualifying bet. A “bet £10, get £30” headline usually means a minimum stake of £10 on a first bet at a stated minimum price. The minimum price is the part that punts the offer out of reach of a tidy arbitrage. A 1/2 (1.50) qualifying line is the floor; 2.0 (1/1) is the typical line for a “bet £20, get £40” offer. Betboro sets the bar higher still: the first bet must carry at least three selections, each at 3/5 (1.60) or greater. That kind of multiple-selection requirement is a way for the bookmaker to keep the qualifying bet inside its own margin, where the bet is most likely to lose the stake the reader is putting up.

The second is the free bet itself — its amount, how it splits across markets, and how long it lives. Coral’s £40 lands as one pot, expiring seven days after issue. BetGoodwin’s £15 splits into three £5 tokens, each aimed at a different market type — a sports single, an accumulator, and a Sub-Cover bet — which is a way of forcing the punter to spread the offer across the bookmaker’s own product mix. QuinnBet, which is on a separate part of the Commission’s register, sets the boundaries more tightly still: free bets are valid for seven days, must be used at odds of 1/2 (1.5) or greater, capped at 50/1, and the accumulator-style Trixie, Patent and Yankee are not allowed — a punter cannot use a free bet to build a multi-leg combination from the punter’s own selection of stakes.

The third is the deposit and payment method. The Commission’s identity checks, in force since 7 May 2019, mean a brand verifies the customer before the first deposit — a fact the headline never mentions. Coral requires the qualifying bet to be paid by debit card or instant bank transfer, which rules out Apple Pay, Revolut Pay and the e-wallets that some readers treat as their default. Octobet, in contrast, attaches a casino bonus to its sports offer — a structure the new promotion rules can no longer require, but which the Commission has not banned outright where the casino portion is genuinely separate from the sports turnover.

Across the ten operators in the shortlist, none of those three pieces is unusual. They are the standard furniture of a UK welcome offer in 2026. The variation is in how tightly each piece is wound, and that is what the write-ups below turn over.

The wagering calculation, in plain numbers

A bookmaker that still asks a customer to roll a cash bonus over many times is now constrained by the 10x cap. Take a £20 cash bonus with a 5x wagering requirement and a minimum price of 1/2 (1.50) on each qualifying bet. The required turnover is £20 × 5 = £100. A punter placing £5 singles at the minimum price needs 20 bets to clear it. At a typical football match odds margin of around 5%, the expected cost of clearing the bonus is £100 × 5% = £5. The bonus is worth £20 in hand and costs about £5 of edge in return, so the net value lands near £15 before the time it takes to clear.

Stretch the multiplier. A £20 cash bonus with a 10x requirement (the new ceiling) and the same minimum price needs £200 of turnover. At the same 5% margin the expected cost is £10, and the net value of the offer falls to about £10. The cap moves the breakeven point by about a third. That is the size of the change the Commission has made, and it is why the headline number on the offer matters less than the multiplier behind it: a smaller bonus with a lower multiplier can clear more profit than a larger bonus at the cap, and a free bet at the same headline size avoids the wagering cost entirely by being a stake-not-returned token from the start.

The figure to watch, on any welcome offer that carries a multiplier at all, is the multiplier relative to the cap. Below 5x the offer is doing the punter a favour; at 10x it is using the full legal allowance. Most of the offers in this shortlist are free-bet structures, where there is no multiplier to clear, and the value sits in the headline amount, the expiry and the qualifying price. The 10x cap bites harder on the offers the shortlist has not been built around.

Welcome offers, head to head

What follows is the ten operators on this list, in the order the Commission lists them, and what each one is honestly worth to a punter who knows how a free bet works.

Coral Offer Structure

Coral’s headline is a familiar shape: bet £20 at minimum odds of 2.0 (1/1), receive £40 in free bets, credited within seven days and expiring seven days after issue. The qualifying payment is restricted to debit card or instant bank transfer, which excludes Apple Pay, Google Pay and the e-wallets. That is a meaningful restriction for a punter who keeps the betting budget in Revolut or Trustly. On the other side, the site’s own product around the offer is wider than the average. A free daily Reward Shaker, an Odds Booster across hundreds of markets, and free-to-play games such as the Football Super Series with a £10,000 jackpot all sit alongside the welcome. Coral is held within LC International Limited, the same group that runs Ladbrokes, which matters for the punter who values a familiar platform but does not want two parallel accounts to manage.

For a punter who already banks by debit card and bets in single lines at evens or longer, this is one of the more straightforward £40-for-£20 swaps on the market. The friction is the qualifying line, not the offer.

Spreadex Offer Structure

Spreadex is the only operator on this shortlist with a dual licence. The Gambling Commission covers fixed-odds betting; the Financial Conduct Authority covers the spread-betting side, and Spreadex’s own homepage makes clear that spread-betting losses can exceed the deposit. The welcome offer is £60 in free bets for a £10 fixed-odds bet, and the free bets are usable across both fixed odds and spread betting, with a 28-day window for the qualifying bet. The qualifying line is the lowest on the shortlist at 1/2 (1.50). The Acca Boosts on the fixed-odds book add 5% cash on a treble and up to 100% on a long football acca.

The pitch is the breadth of the offer: a single welcome that feeds into both products. The pitch is also the catch. Spread betting is a different product from fixed odds, and the punter who treats a free bet as a fixed-odds token may find it a poor fit on the spread side. Spreadex suits a punter who already understands both books and wants one welcome offer to do the work of two.

William Hill Offer Structure

William Hill does not pin a single headline welcome in the same shape the rest of the shortlist does, and the value proposition is the platform around the offer. The Football Acca Boost runs from 3% on a double to 200% on twenty or more legs, with a £10,000 ceiling per online bet, and runs until 30 May 2027. A punter who bets accumulators already is paid in cash for adding legs, not in free bet tokens. The welcome offer itself is on the standard free-bet model, and the Acca Boost sits in addition rather than in place of it.

The trade-off is platform age. William Hill has been on the British market since before the Gambling Act 2005, and the Commission’s remote licence under WHG (International) Limited has been live through every tightening of the rulebook. The punter who values longevity and a wide football market gets a familiar offer. The punter who values a small operator with a tight welcome will look elsewhere.

Fitzdares Offer Structure

Fitzdares is a smaller bookmaker with a payments profile that suits a particular kind of punter. Apple Pay, Mastercard and Visa are accepted, and the withdrawal profile is unusual for the shortlist: Visa withdrawals are usually same-day, while Mastercard can take up to 48 hours. The welcome offer is listed in-app and on site under the operator’s own terms. The Commission’s licence is held by Fitzdares Limited under account 400, one of the older account numbers on the register, and the site does not lean on the giant free-bet headline.

Fitzdares suits a punter who places the value of an offer on the speed of a withdrawal rather than on the size of the headline token. A punter who needs a winnings withdrawal in hours rather than days has a clear reason to be here. A punter chasing the largest free bet on the market will not find it.

Betboro Offer Structure

Betboro runs a 100% matched free bet up to £25 on the first qualifying wager, which is one of the more generous matched structures on the shortlist. The catch is the qualifying bet: a first bet of £5 to £25 with at least three selections, each at 3/5 (1.60) or higher. That requirement pushes the qualifying bet into accumulator territory, where the bookmaker’s margin compounds across the legs. A treble at the floor margin on each leg carries an overround higher than a single at the same price, and the punter is paying that extra edge to unlock the matched free bet.

Betboro suits a punter who already bets accumulators as a default and wants the matched structure to reward that habit. It is the wrong fit for a punter whose betting is single-line football and horse racing, where the qualifying bet would feel forced.

VBet Offer Structure

VBet’s welcome offer is a £10 free bet if a new, verified customer stakes £10 or more on a first bet that loses. That is a “no-worse-than-flat” structure: the worst the punter can do is break even on the first bet, and the upside is a free bet on top. The verification line is the friction. The Commission’s identity checks mean the punter cannot deposit and bet anonymously; a new VBet customer completes the same verification process as on any other licensed site, and the offer triggers only after the first bet settles as a loss.

The licence sits with SCGO Limited under account 44662. The pitch is simple, the size is small, and the punter who wants the lowest possible entry cost has a clear route here. A punter looking for a headline figure on the welcome page will not find one.

BetGoodwin Offer Structure

BetGoodwin’s welcome is “Bet £10, get £15 in free bets”, split three ways: a £5 sports single token, a £5 accumulator token, and a £5 Sub-Cover token. The split is a guided tour of the bookmaker’s own product mix, and the punter who wants one free-bet pot to use as they choose will feel corralled. The licence is held by Goodwin Racing Limited under account 2927, a smaller name on the register.

The Sub-Cover token is the piece that punts the offer away from the standard free-bet shape. It is structured around horse-racing place markets, where the bookmaker hedges part of the risk on a selection. A punter with a horse-racing book will read the structure as a reason to be here; a punter with a football book will not.

Octobet Offer Structure

Octobet runs a 50% back-as-free-bet offer up to £50, plus a £10 casino bonus for new customers. The two pieces sit side by side rather than being tangled together, and that matters under the new promotion rules. The Commission’s ban on mixed-product promotions targets offers that require play across product types to clear a single bonus. Where the casino portion is a separate token with its own terms, the structure is allowed. Octobet’s site presents the two pieces as distinct, and the punter can use the sports token without touching the casino credit.

The licence is held by Octopus Game Limited under account 62545. The pitch is a larger sports free bet than the typical £20-for-£40 swap, with a small casino bonus attached. The punter who wants the larger sports free bet has a route; the punter who is wary of any casino prompt will look elsewhere.

Betmaster Offer Structure

Betmaster’s site is operated by BM Solutions GB Ltd, a Maltese-registered company, and the Commission’s account is 65699. The welcome offer is listed on site under the operator’s own terms. There is no single headline token the way Coral or VBet publish, and the value sits in the rest of the platform rather than in a signature welcome. The Maltese operating company is a reminder that a Commission licence is required at the point of consumption, and the operator behind the licence is free to sit in any jurisdiction that the Commission accepts under its licence conditions and codes of practice.

Betmaster suits a punter who treats a welcome offer as one product among many and is happy to read the small print on the day. The punter who wants the headline on a postcard will not find one here.

DAZN Bet Offer Structure

DAZN Bet sits on the Commission register under DZBT Limited, account 48756, and the welcome offer is listed in-app under the operator’s own terms. The product around the offer is the wider part of the pitch: Cash Out (with the standard caveat that availability is not guaranteed and bets stand if Cash Out is unavailable), Bet Builder, daily bet boosts, and in-play betting. The safer-gambling toolkit covers deposit, loss and wagering limits, which is the full set the Commission’s safer-gambling rules ask for at the platform level.

DAZN Bet suits a punter who already bets in-play and through Bet Builder, and who wants the welcome offer as the entry point into that toolkit. The punter whose book is singles at the weekend will find more value on a smaller free bet elsewhere.

What the licence really buys

A Gambling Commission remote licence is not a quality mark. It is a permission to take bets from customers in Great Britain under the Gambling Act 2005, with the conditions and codes of practice that come with the licence attached. The conditions cover identity verification before the first deposit, the integration of GAMSTOP for self-exclusion, the financial vulnerability check that applies once a customer’s deposits minus withdrawals cross £150 in a rolling 30-day window, the ban on credit-card deposits, and the new promotion rules that cap wagering at 10x and ban mixed-product offers. None of those conditions is optional, and a Commission enforcement notice on a single brand has a way of reaching the rest of the market by way of the licence condition itself.

The punter who wants to check a brand is on the register can do so through the Commission’s public search, by business name, trading name, domain or account number. The number on the brand’s site is the number to look up, and the licence categories the brand holds are the categories under which it is allowed to take bets. None of the brands on this shortlist is “the only” licensed operator; the Commission’s register lists many more, and any exclusivity claim on a single brand is a marketing line rather than a regulatory fact.

Offshore is a separate matter. A brand whose facilities are used in Great Britain without a Commission licence is operating illegally under section 33 of the Gambling Act 2005, aimed at the operator. The punter who bets with an unlicensed brand loses the protections the licence carries: no GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, and no British consumer redress if funds are withheld. The 10x bonus cap and the financial vulnerability check do not apply. To call such a site “legal to use” is a misreading; the honest framing is that the punter is outside the British regulatory perimeter.

The safer-gambling layer

A welcome offer sits inside a safer-gambling framework that the Commission has been tightening since 2019. The headline pieces are well-rehearsed: minimum age 18, identity checks before the first deposit, GAMSTOP for online self-exclusion across all licensed operators, and the financial vulnerability check at the £150 rolling 30-day threshold. The pieces that are still moving are the deposit-limit rules under Remote Technical Standard 12, the first phase of which has applied since 31 October 2025 and a second phase postponed to 30 September 2026, and the financial risk assessments (the “affordability checks” the press has been writing about) which the Commission announced in a staged plan on 7 July 2026 with no start date.

The framework is not state-imposed in the way a state monopoly would be. Limits are the customer’s choice, set inside the operator’s own platform, with the operator required to make them available. The punter who wants a hard ceiling on deposits or losses can set one on any of the ten sites in the shortlist. The punter who wants to self-exclude from online betting across the whole licensed market registers with GAMSTOP for a period of six months, one year, five years, or five years with auto-renewal, and the exclusion stays in place for a further seven years after the minimum period unless the customer asks GAMSTOP to remove it. The bookmakers on this shortlist, along with every other online operator, are GAMSTOP participants.

Help lines are listed on every operator’s safer-gambling page: GamCare (which runs the National Gambling Helpline), GambleAware, the NHS gambling clinics, and Gamblers Anonymous. The framework is built so that the punter can act before the welcome offer becomes a habit the budget cannot carry, and a brand on this shortlist is required to make the route visible.

What the welcome bonus actually costs, in sum

Pull the threads together. A £20 cash bonus at 5x with a £5 stake at minimum odds of 1/2 (1.50) needs 20 bets to clear, costs about £5 of margin in expected loss, and lands the punter at about £15 net. The same bonus at the new 10x cap needs 40 bets and costs about £10 in expected loss, halving the net value of the offer. A free bet of the same headline value skips the wagering entirely and delivers the upside on the first bet, minus the stake that is not returned with a win. The size of the headline is not the size of the value; the multiplier, the minimum price, the expiry and the stake-returned rule are.

For a punter comparing welcome offers on a like-for-like basis, the order of priorities is the multiplier, the minimum qualifying price, the expiry of the free bet, the stake-returned rule, and only then the headline figure. The Commission has put a ceiling on the first of those, and the shortlist above is built largely on offers that avoid the multiplier altogether. The choice between Coral’s £40, Spreadex’s £60, BetGoodwin’s £15 in three tokens, VBet’s safety-net £10 and Fitzdares’ in-app offer is not a choice between good and bad; it is a choice between different shapes of the same kind of offer. The punter who knows which shape fits the betting book is the punter who gets the most out of the comparison.

Frequently asked questions

Welcome bonuses are an entry point, and these are the questions punters most often ask when comparing the offers on a British-licensed site.

How do I claim a betting welcome offer?

Open an account with the bookmaker on its own site or app, complete the identity check the Gambling Commission requires (name, address, date of birth) before the first deposit, make a qualifying deposit by a payment method the offer accepts, place the first bet at the minimum price the offer names, and let the bet settle. The free bet is credited on the operator’s own terms — Coral within seven days, others within 48 hours — and the punter then has the expiry window the terms give.

Which betting site offers a welcome bonus in Great Britain?

Every site on the Commission’s public register that takes sports bets does, and the register runs to many more than the ten on this shortlist. The brands named here all hold a remote general betting standard (real events) licence, and each lists its own welcome on its site or app under its own terms. The list is not a ranking and not an exclusive one; the punter who wants a wider comparison has the Commission’s search by business name, trading name, domain or account number.

Which betting site has the best welcome bonus?

The honest answer is that “best” depends on the betting book. A punter who places accumulator bets gets more from Betboro’s matched structure or William Hill’s Acca Boost than from a single-line free bet at Coral. A punter who values a low qualifying line gets more from Spreadex at 1/2 (1.50) than from Coral at 2.0 (1/1). A punter who wants a small entry point gets more from VBet’s safety-net £10 than from a larger matched offer. The “best” offer is the offer the punter will actually use, on the markets the punter actually bets.

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

Since 19 January 2026 the Gambling Commission has capped wagering requirements on bonuses at 10x. A £10 bonus can require no more than £100 of qualifying bets. The cap applies to bonuses with a wagering condition; whether it applies to free bets with no wagering condition has not been established. The 10x figure is the legal ceiling, and a bookmaker demanding more than that is in breach of its licence conditions and codes of practice.

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

The minimum odds are the floor price the qualifying bet must carry; a “bet £10 at minimum odds 2.0” line means the first bet must be a single at 1/1 or longer, or an accumulator whose combined price is 2.0 or longer. Bets below the minimum odds do not qualify, even if the stake is right. The wagering requirement is the multiple of the bonus that must be turned over in qualifying bets before the bonus becomes withdrawable; a £20 bonus at 5x means £100 of qualifying bets. The two work together: a high minimum odds and a high multiplier push the offer into a part of the book the bookmaker’s margin favours.
