A “free” £40 has a price tag, and the price is rarely the £20 you put down. This page ranks the best betting sign-up offers in Great Britain for 2026 against that single question: what does the offer actually cost the customer who claims it, and what does the customer walk away with once the small print has done its work? The honest lead is the Gambling Commission’s promotion rules that took effect on 19 January 2026. Wagering requirements on bonuses are now capped at 10x, and any offer that drags a customer across two product types — betting plus casino, sports plus free spins — is out. What sits underneath that headline is a smaller, sharper question: how much betting does the offer force, at what minimum price, and by when? That is the question this guide is built to answer.

Data current as of 30 October 2026, verified against the Gambling Commission’s public register and each operator’s own published terms.

The cost of a sign-up offer, before the marketing does its work

What the marketing says versus what the terms demand

A sign-up offer is a contract with three moving parts: the amount paid out, the conditions the customer has to meet before it is paid out, and the value the offer actually carries once those conditions are priced in. The marketing speaks only about the first part — “Get £40 in free bets for a £20 stake” — and quietly assumes the reader already knows the other two. The work this page does is the inverse: name each part, give the figures the operator’s own terms supply, and let the reader weigh the deal on its real terms rather than on the headline.

Across the ten bookmakers reviewed below, the headline amounts range from £10 to £60 in free bets, the qualifying bets from a single £5 punt to a £20 something-at, and the minimum odds from 1/1 (2.0 decimal) up to 3/1 (4.0). On top of those terms sits the new rule that no bonus can carry a wagering multiple above 10x — a £10 bonus at 50x required £500 of qualifying bets before; under the cap no more than £100. Most sign-up offers at the GB-licensed firms reviewed here now sit well inside that ceiling, but the rule still matters because it tells a reader how to read the conditions page: any clause demanding more than 10x turnover on a bonus is either a relic of an older offer or a mis-statement, and either way it warrants a second look.

The three things every welcome offer hides

Every sign-up offer carries three conditions a reader has to weigh before the headline means anything:

• The minimum price. A qualifying bet at minimum odds of 2.0 (1/1) is not the same bet as one at minimum odds of 1.5 (1/2). The higher the floor, the more the customer has to back something the market does not think is a near-cert, and the more often the qualifying bet will lose. SBK asks for a £20 bet at 3.0 (2/1) before it credits £60 in free bets, and that floor alone cuts the qualifying leg out of most short-priced favourites.
• The expiry clock. Most free bets in this set last seven days from issue. Coral’s £40 in free bets expires seven days after the tokens land in the account, and Unibet’s £40 runs on the same clock. A free bet is worthless the moment it expires, and a customer who places one qualifying bet, takes a phone call, and comes back the following week has watched the offer vanish.
• The stake-not-returned rule. A free bet pays the winnings only; the stake of the free bet is not returned with a win. A £10 free bet at 5.0 returns £40 in profit, not £50. This is the single clause most likely to be missed, because every other line of the offer speaks in terms that suggest otherwise.

The 10x cap and the seven-day clock together tell a reader what a welcome offer is really worth: whatever the headline says, the offer’s value sits somewhere between the headline figure and the headline minus the cost of the qualifying bet at the minimum price, the cost of placing the free bet before it expires, and the cost of betting at prices that often mean the free bet itself does not win. Nothing in that arithmetic is hidden, and nothing in it requires the reader to take a particular view of any sport.

The 10x bonus cap and the mixed-product ban: what changed on 19 January 2026

Wagering multiple: capped at ten

The Commission’s promotion rules in force since 19 January 2026 put a hard ceiling on how much betting a bonus can demand. Under the old regime, a £10 bonus could carry a 50x wagering requirement — £500 of qualifying bets before any of the bonus is withdrawable. Under the new rule, the multiple is capped at 10x: a £10 bonus can demand no more than £100 of qualifying bets, and a £100 bonus no more than £1,000. Welcome offers at the licensed firms reviewed here tend to fall below the cap rather than at it, but the cap still does two jobs at once. It tells a customer what an aggressive offer looks like and where to stop reading; and it tells the operator what the upper edge of the market now is.

A sign-up offer in this set is rarely a wagering-heavy bonus in the first place. The welcome package at most of these brands is a free-bet cluster — £20 to £60 of bet credits unlocked by a single qualifying wager — rather than a deposit match with a turnover requirement. The cap matters, but it bites hardest on the second-deposit and reload bonuses that licensed operators run through the season, where the wagering multiple was once the lever that turned a £50 headline into £500 of forced betting.

Mixed-product promotions: banned

The second half of the rule, less quoted but equally firm, is the mixed-product ban. Any offer that requires a customer to gamble on two or more product types — sports betting tied to casino, sports betting tied to bingo, a sportsbook bonus that hands out free spins — is now prohibited. The Commission’s framing is direct: a customer who opens a sportsbook account to claim a free-bet offer should not find themselves steered into a roulette lobby on the way to the cash-out page. The welcome packages below comply with that by staying inside sports only.

What the cap does not cover

The rule leaves two questions open and the most important is the first. Whether the 10x ceiling applies to free bets with no wagering condition — the bet-credit-style offers that most of this set actually runs — is not established in the published guidance. Most licensed firms in Great Britain do not attach a wagering multiple to a free bet at all; the free bet is one stake, at the customer’s chosen price, and the winnings (not the stake) come back. That is the cleaner structure, and it is the structure most of the offers below follow. The cap’s effect, in practice, is to push the rest of the market towards that model.

The second open question is whether there is any cap on the money value of a bonus itself. There is not. A £500 free-bet welcome would still be legal, in headline form, provided no clause inside it demands more than 10x turnover. The cap is on turnover, not on payout.

How to use the cap as a reader

Three practical habits fall out of the rule. First, treat any offer that demands more than 10x turnover on a bonus as either historic or mis-stated; either way, do not claim until the terms have been re-read. Second, ignore any “bet on football, get free spins” headline; it is no longer compliant, and a licensed firm running it would be in breach. Third, weigh the qualifying bet on its own merits before counting the free bet as income. The cap is a backstop. The real cost sits in the qualifying leg.

Ranking the best betting sign-up offers in 2026

How this ranking was built

The ten operators below are ranked on what the sign-up offer actually returns after the qualifying bet and the small print have done their work. That means the headline amount, the minimum price the qualifying bet has to clear, the expiry on the free bets, and the licence standing of the brand. The table below carries the licence and the headline structure; the operator blocks underneath carry the conditions in full, the features each brand layers on top of the welcome, and the verdict a cost-led reading produces.

One ranked above all the rest on the headline terms sits at the bottom of the cost-led reading, and that is the point. Sky Bet’s £30 in free bets after a 5p qualifying bet looks generous on first read and stays generous on second read; SBK’s £60 in free bets after a £20 qualifying bet at 3.0 looks generous on first read and tightens considerably once the minimum price is priced in. The ranking rewards the offer that demands the least and pays the most, in that order.

The ten licensed bookmakers at a glance

The table carries each brand’s Gambling Commission account number alongside its parent company, because a licence is the first thing to verify before any offer is claimed. Account numbers reconcile to the Commission’s public register, which is searchable by business name, trading name, domain or account number. Every brand listed here is on that register under a current remote general betting standard (real events) licence. None of them is “the only” licensed GB bookmaker: the register lists several hundred.

Sky Bet

Sky Bet’s welcome offer for new customers is £30 in free bets, credited as three £10 free bet tokens after a deposit of at least £5 and a first single or each-way bet of at least 5p at odds of 1/1 (2.0) or greater. The 5p qualifying bet is the cheapest in this set by a distance, which moves Sky Bet to the top of the cost-led ranking: a customer can clear the qualifying leg for five pence on anything priced at evens or longer, take the three £10 free bets, and place each of them on a market of their choice within the seven-day window. The headline is modest but the conditions are the lightest on the page, and on a ranking that weighs what the offer costs the customer to clear rather than what it advertises, that is decisive.

Beyond the welcome, Sky Bet layers daily odds boosts and a Super Boosts feed on selected football and horse racing markets. The brand sits inside the Flutter Entertainment group, which also runs Paddy Power and Betfair, and the Sky Bet app carries Best Odds Guaranteed on UK and Irish horse racing, a Cash Out function on most markets and a Request-a-Bet feature on the bigger fixtures. The terms on free bets follow the standard GB shape: stake not returned, free bet tokens expire seven days after issue, single bets only. There is no wagering requirement on the welcome package, which keeps the offer on the right side of the Commission’s 10x cap and removes the only kind of condition that could push a customer into a long, costly grind.

Verdict. Sky Bet is the cheapest welcome offer to clear in this set, and the only one priced in single-figure pence on the qualifying leg. For a customer who reads the conditions carefully and has a Sky account already, the offer is worth claiming. The free bets are modest in headline, but the cost of getting them is the lowest on the page.

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 7 days and expiring 7 days after issue, for new GB customers who opt in. The qualifying leg is twice the size of Sky Bet’s, the minimum price is twice as high, and the headline payout is £10 larger, but the trade works out in roughly the same shape: a £20 bet at evens-or-longer unlocks £40 in free-bet tokens, with seven days to use them. Coral’s welcome offer has to be qualified with a debit card or instant bank transfer, which is standard for the Ladbrokes-Coral group and excludes credit cards by design. Coral’s site lists Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly among its payment options, so a customer who wants to fund with anything other than a card or a bank transfer will not be able to clear the welcome.

Beyond the welcome, Coral runs a free daily Reward Shaker that hands out free bet prizes at random, an Odds Booster on hundreds of markets, and a free-to-play Football Super Series game with a £10,000 jackpot. The wider Coral product sits on the same LC International Limited licence as Ladbrokes, which means the two brands share their safer-gambling tools, their payment rails and their customer support. In-play markets on Premier League, Champions League and the major US sports run deep, and the brand’s football offering is among the broadest on the high street.

Verdict. Coral’s £40 in free bets is the highest headline in this set from a brand with a high-street pedigree, and the conditions sit in the middle of the range. A customer who can fund with a debit card or instant bank transfer and place a £20 qualifying bet at evens-or-longer will find the offer fair. The seven-day expiry on both the issue window and the free bet tokens is a tighter clock than most.

Unibet

Unibet’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 free bets expiring within 7 days of issue, for new GB customers using a debit card or instant bank transfer. The structure mirrors Coral’s headline-for-headline, and the conditions are the same on the qualifying bet, the minimum price and the expiry. The two brands sit within different parent groups — Unibet is part of the Kindred group, Coral is part of Entain — but the welcome package reads identically because the GB market has converged on a £40-at-2.0 shape across the major licensed brands.

What Unibet adds on top is the live-streaming product. Unibet TV streams selected football, tennis and horse racing events to logged-in customers, and the brand carries Best Odds Guaranteed on horse racing, Cash Out on thousands of markets, Bet Builder on football, daily Uniboosts and a wide in-play offering. Unibet has been operating since 1999, and its UK site is run by Platinum Gaming Limited, Gibraltar, under Gambling Commission account 45322. The brand sits inside a long-established European operator with a deep live-product, and the welcome offer acts as an entry ticket to that product rather than a stand-alone headline.

Verdict. Unibet’s welcome offer is fair on its own terms and fair by comparison to Coral’s. The live-streaming product and the breadth of the in-play offering make the brand a better long-term home than the headline suggests, and the welcome offer is a sensible way to try it. For a customer who values live streaming and horse racing BOG, Unibet sits ahead of most of the set on features even if the welcome itself is mid-table.

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 qualifying leg is £10 and the headline payout is split into three smaller tokens rather than a single free bet, which means the customer has to think about three separate placements rather than one. The acca and Sub-Cover tokens are tied to a particular bet type rather than to any market the customer chooses, which is the trade-off the brand offers in exchange for a slightly larger headline against a slightly smaller qualifying stake. Goodwin Racing Limited, the licence holder, is an independent British bookmaker focused on horse racing, and the welcome package reflects that focus: the Sub-Cover token is a horse-racing product that pays out if the customer’s selection is beaten by the favourite, and the acca token is tied to a multi-leg wager.

Beyond the welcome, BetGoodwin runs a tighter book than the larger brands and tends to publish odds that favour the customer on the smaller fixtures. The product offering concentrates on horse racing, greyhound racing and the major UK football leagues, with in-play markets on selected events. The brand’s licence history stretches back to the original Gambling Commission account numbers, and the parent company’s racing connections show in the customer service: withdrawals to debit cards typically clear inside two hours during racing hours, which is faster than the larger brands on the same rails.

Verdict. BetGoodwin’s £15 in three tokens is a smaller headline than the £40 packages above, but it is also the welcome offer of an independent racing-focused firm with sharper prices on smaller meetings. A racing-first customer who values the Sub-Cover token will get something the bigger brands do not offer. A customer looking for the biggest headline in the set should look elsewhere.

Spreadex

Spreadex runs both fixed-odds betting and financial spread betting under the same account. The new customer offer is £60 in free bets for a £10 fixed-odds bet, with the free bets usable across fixed odds and spread betting, and the qualifying bet must be placed within 28 days of opening the account. The minimum odds on the qualifying bet are 1/2 (1.5), and the 28-day window is the longest qualifying period in the set. Spreadex is regulated by the FCA for spread betting and by the Gambling Commission for fixed-odds betting, and the company’s own materials note that spread betting losses can exceed the deposit — the only brand in this set where that warning is published on the homepage.

The fixed-odds product carries Acca Boosts that pay a cash boost from 5% up to 100% on football accumulators of three or more selections, depending on the number of legs, and the brand’s spread-betting product offers a separate point-and-stake-trading book on sports and financial markets. The hybrid structure is rare in the GB market, and it suits a customer who already trades spread markets and wants to use free-bet value across both books. A customer who is not already a spread bettor should treat the offer as a fixed-odds welcome with an opt-in spread product attached, because the spread book carries a real risk that fixed-odds betting does not.

Verdict. Spreadex’s £60 headline is the largest free-bet offer in this set, and the 28-day qualifying window is the most generous. The minimum odds on the qualifying bet are the lowest on the page. For a customer who understands both sides of the brand’s book, the offer is the most generous here. For a customer who has never spread bet, the loss-can-exceed-deposit warning on the homepage is the reason the offer carries the largest headline.

BoyleSports

BoyleSports’ sports welcome offer for UK players is £20 in free bets when a £10 bet is placed (€30 in free bets for a €10 bet for Irish players). The qualifying leg is £10 and the headline is £20 in free bets, with a separate euro-denominated offer for Irish customers. The brand also runs BoyleSports Acca Insurance, which refunds a stake as a free bet if one leg of a qualifying accumulator lets the bet down, and BoyleSports Acca Loyalty, which pays a free bet on accas of five or more settled legs. Acca Insurance requires opt-in, a minimum stake of £5, minimum odds of 1/2, and pays a maximum refund of £20 as a free bet that expires in seven days; Acca Loyalty requires opt-in, a £5 minimum stake, minimum combined odds of 3/1, and five or more settled legs.

The brand’s wider product covers UK and Irish horse racing, football, Gaelic games and the major US sports, and the in-play book runs deep on football. The Irish heritage shows in the breadth of the racing product and the depth of the football offering on the League of Ireland and the English Football League. BoyleSports runs on a Gibraltar licence within the GB market, and the operator’s GB remote general betting standard licence is held by BoyleSports (Gibraltar) Limited. The brand is a mid-sized licensed bookmaker by GB market share and sits inside the welcome-package range.

Verdict. BoyleSports’ £20 headline for a £10 qualifying bet is a fair middle-of-the-market welcome, and the Acca Insurance and Acca Loyalty products add value beyond the welcome. For a customer who places accumulator bets as their main product, the Acca Insurance in particular is the standout feature in the set. The Irish side of the brand offers a slightly larger headline for euro-denominated customers.

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 structure is the only one of its kind on this page: the customer does not get a free bet on signing up — they get a free bet if their first bet loses. That is the “second-chance” shape rather than the “free bet on sign-up” shape, and it changes the calculation. The customer has to place a qualifying bet at their own price and on their own market, and only the loss of that bet converts into a free bet. A winning first bet returns the customer’s stake plus winnings and ends the welcome. A losing first bet refunds £10 in free-bet credit.

The brand’s wider product covers football, basketball, tennis and the major US sports, with in-play markets on selected events and a smaller welcome footprint than the major brands. SCGO Limited holds the GB licence, and the brand’s licence position is current on the Commission’s public register. VBet is one of the smaller licensed brands in this set by market share, and the welcome offer reflects that scale: lower headline, simpler structure, narrower product spread.

Verdict. VBet’s welcome offer rewards the customer who loses their first bet rather than the customer who signs up. For a customer who is testing a new account and willing to back something they accept might lose, the offer returns £10 in free bets on a £10 first bet. For a customer who plans to win their first bet, the offer pays nothing. The shape suits the cautious first-time better more than it suits the experienced one.

SBK

Smarkets also runs the SBK sportsbook, whose UK welcome offer is a £20 first deposit and £20 bet at minimum odds of 3.0 (2/1) for £60 in free bets within 48 hours. The minimum odds are the highest in this set — a 2/1 qualifying bet is not a near-cert by any reading — and the headline is the joint-largest at £60. The shape is the opposite of Sky Bet’s: a customer has to back something the market thinks is a real outsider before they get the welcome package, and the qualifying bet has to be placed within 48 hours of the deposit. The free bets land inside 48 hours and follow the standard stake-not-returned rule.

SBK sits inside the Smarkets exchange licence, which makes it the only betting exchange sportsbook in this set. The product carries Bet Builder, Cash Out and live horse racing streams, and the brand’s exchange heritage shows in the in-play prices on football and horse racing. The welcome offer is the most demanding in the set on the qualifying leg, which is the trade-off for the larger headline figure.

Verdict. SBK’s £60 headline is matched by the highest qualifying minimum in the set, and a customer who backs something at 2/1 will lose more often than they would at Sky Bet’s 5p-at-evens qualifying leg. The offer suits a customer who already plans to back something at 2/1 or longer anyway; it does not suit a customer who would have to find a bet at 2/1 just to qualify. The exchange licence underneath is the strongest feature of the brand.

bet365

bet365 does not publish a fixed welcome headline on a marketing page. The brand’s offer is shown in the app at sign-up and governed by the operator’s customer terms, and the figure varies by jurisdiction, deposit method and the time of year. bet365 offers Bet Builder+, which combines markets from one event into a single bet available pre-match and in-play, Super Boosts on selected markets, Winnings Boosts on Bet Builders and selected singles, and daily Bet Boosts. Hillside (UK Sports) ENC holds the GB remote general betting standard licence.

The brand’s product depth is the largest in this set. In-play markets on football, tennis, basketball and the major US sports run deeper than any competitor on the page, and the in-play pricing is the benchmark for the GB market. Live streaming on the bigger book covers hundreds of events, and the Bet Builder product on football is the most developed in the GB market. The licence holder is part of the Coates family’s wider betting group, and the GB operation sits inside a large, well-resourced product team.

Verdict. bet365 does not publish a fixed headline, and the welcome figure that appears in the app at sign-up is the one the customer reads. For a customer who values product depth over headline amount, the brand is the strongest in this set. The trade-off is that the offer is not predictable from outside the app, which means a careful reader checks the sign-up screen before depositing rather than relying on a marketing line.

BetVictor

BetVictor offers regular price boosts, acca offers and free bets on selected events, with welcome offers shown in the app and governed by its customer terms. The brand’s welcome figure sits inside the app and follows the same shape as bet365’s: it is not published on a marketing page and the figure varies by sign-up window. The brand carries a long-standing GB licence held by BetVictor Limited, and the wider product covers football, horse racing, tennis and the major US sports, with in-play markets on selected events.

BetVictor’s product sits in the middle of the GB market: smaller than bet365’s product, broader than the racing-focused independents, and concentrated on football and horse racing. The brand’s history as a UK-owned bookmaker shows in the racing product, and the in-play football offering is competitive with the larger brands on the bigger leagues. The welcome offer is the smallest named headline in this set, and conditions are governed by the in-app terms.

Verdict. BetVictor’s welcome offer is shown in the app rather than on a marketing page, which means the customer reads it on the sign-up screen. The brand suits a customer who already has a BetVictor account or wants a long-established UK-owned bookmaker, and the welcome is the price of admission. For a customer comparing offers on headline alone, the brand sits behind the bigger welcome packages; for a customer comparing on product, it sits in the middle of the set.

How to read a betting sign-up offer, in seven clauses

The seven-day rule

Most free bets at the licensed GB bookmakers in this set expire seven days from issue. Coral’s tokens, Unibet’s tokens and Sky Bet’s tokens all run on the same clock; BoyleSports’ tokens run on a seven-day clock as well; the SBK tokens land inside 48 hours but expire on the standard cycle. The seven-day rule is the single most important clause in any welcome package because it determines whether the customer can use the free bet before it vanishes. A customer who places a qualifying bet on a Saturday afternoon, intends to use the free bets on the following Saturday’s racing, and finds that the tokens expired on the Friday has watched the offer disappear.

The stake-not-returned rule

A free bet pays winnings only. A £10 free bet at 5.0 returns £40 in profit on a win, not £50; a £20 free bet at 3.0 returns £40, not £60. The rule is the single clause most likely to be missed, because every other line of the offer speaks in terms that suggest otherwise. A “£40 in free bets” offer is not a £40 payout on a winning free bet — it is a £40 stake with the winnings on top. The distinction matters more on the larger free bets than on the smaller ones, and it matters most on the longer prices where the winnings dominate the return.

The minimum odds

The minimum odds clause tells the customer what kind of selection the qualifying bet has to be. Sky Bet’s 1/1 (2.0) minimum is the cheapest in the set on the customer side, because a bet at evens is roughly a coin-flip; SBK’s 3.0 (2/1) minimum is the most expensive, because a bet at 2/1 wins only a third of the time in a fair market. The minimum odds clause does not affect the customer who places the qualifying bet on a selection they were going to back anyway; it matters for the customer who has to find a bet at the floor just to qualify. The latter is the customer who ends up paying the offer’s hidden cost.

The qualifying payment method

Coral and Unibet both require the qualifying deposit and bet to be placed via debit card or instant bank transfer; Apple Pay, Google Pay and the e-wallets do not qualify the welcome at either brand. Other operators in this set do not publish a payment-method restriction on the welcome offer, and the default is that any payment method the operator accepts for sports betting also qualifies the welcome. A customer who funds with Apple Pay and finds the welcome uncredited has read the wrong offer; a customer who funds with a debit card has read the right one.

The wagering multiple

The 10x cap on bonus wagering that has been in force since 19 January 2026 means the licensed firms in this set cannot demand more than ten times the bonus amount in qualifying bets before withdrawal. Most of the welcome offers above carry no wagering multiple at all — they are free-bet packages, not deposit-match bonuses — and the cap’s effect is on the reload and second-deposit offers that licensed operators run through the season. A reader who sees an offer that demands more than 10x turnover on a bonus has either found a non-licensed brand or a mis-statement, and either way should not claim until the terms have been re-checked.

The verification requirement

GB-licensed bookmakers verify name, address and date of birth before a customer can deposit or gamble, and the verification has run on every licensed brand since 7 May 2019. A customer who claims a welcome offer before verification completes will not have the free bets credited, and a customer who cannot verify will not have an account at all. The verification is a one-off cost in time, not in money, but it is the cost most likely to delay a welcome offer by 24 to 48 hours and the cost most likely to send a customer to an unlicensed brand that does not ask.

The single-bet and each-way rule

Free bets at the licensed GB bookmakers in this set can usually be placed as a single bet or each-way, but they cannot be combined into accumulators, and Trixies, Patents, Yankees and Lucky 15s are typically excluded. QuinnBet’s published rule is the clearest in the set: free bets are valid for seven days from credit and can be used on any market at odds of 1/2 (1.5) or greater, with maximum odds of 50/1; straight accumulators are allowed but Trixies, Patents and Yankees are not. A customer who splits a £10 free bet into a Lucky 15 will find the bet refused at the betting slip; a customer who places the £10 free bet as a single on a 5/1 shot will see the bet accepted.

The calculation: how much betting does the welcome actually demand?

The inputs

The Commission’s 10x cap has been in force since 19 January 2026. A £10 bonus at the cap requires £100 of qualifying bets before the bonus is withdrawable; a £50 bonus at the cap requires £500; a £100 bonus at the cap requires £1,000. None of the welcome offers in this set carries a deposit-match bonus of that shape. Most are free-bet packages that ask for a single qualifying wager rather than a turnover requirement, which is why the cap’s effect is felt more on reload offers than on welcome packages. The calculation below uses the cap as the upper edge of the welcome-market’s turnover demand.

The arithmetic

A £20 welcome bonus under the 10x cap requires no more than £200 of qualifying bets. At a minimum stake of £10 per bet, that is twenty qualifying bets; at £20 per bet, ten. The exact number depends on the customer’s stake size, the minimum price of each bet, and the operator’s house rules on minimum stake.

For the free-bet packages that dominate this set, the calculation is simpler. Coral’s £40 free bet package requires one £20 qualifying bet at minimum odds of 2.0 (1/1); Sky Bet’s £30 package requires one 5p qualifying bet at minimum odds of 1/1 (2.0); SBK’s £60 package requires one £20 qualifying bet at minimum odds of 3.0 (2/1). The turnover on each package is one bet, not a sequence of bets, and the cost of the qualifying leg depends on the customer’s view of the selection they have to place.

The expected cost

A free-bet package carries an expected cost to the operator’s book on the qualifying bet, and a customer who reads the offer as “free £40” pays that expected cost in the form of a bet they would not otherwise have placed. The expected cost on a £20 qualifying bet at minimum odds of 2.0 is roughly £10 — the difference between the bet’s expected value at fair odds and the bookmaker’s margin on the selection. The customer collects the £40 free bet on top, and the net value of the package is roughly £30 minus the cost of placing the free bet itself before it expires.

The result

Stated as a band: the qualifying leg of a free-bet welcome at a GB-licensed bookmaker costs the customer between 5p and £20 of stake they would not otherwise have placed, plus the expected loss on the selection they had to choose to clear the minimum price. The free bet itself returns between £10 and £60 of stake, paid back as winnings only, with seven days to use. The package’s net value to the customer is the headline minus the cost of clearing the minimum, and that is the figure the customer weighs against the alternative of opening an account without a welcome offer.

The 10x cap matters most when a welcome offer does carry a turnover requirement, and the welcome offers in this set mostly do not. The cap is the backstop; the real cost sits in the qualifying leg. A reader who reads both clauses together — the headline figure and the qualifying conditions — sees the offer on its real terms, which is what this ranking has been built to deliver.

Where sign-up offers meet the law

The Gambling Commission and the Gambling Act 2005

The Gambling Commission, a non-departmental public body sponsored by the Department for Culture, Media and Sport, licenses the whole commercial betting market in Great Britain under the Gambling Act 2005. Northern Ireland is outside the 2005 Act and operates under older legislation, so a “GB licence” regulates Great Britain — England, Scotland and Wales — and nothing else. Since the Gambling (Licensing and Advertising) Act 2014, an operator whose remote facilities are used in Great Britain needs a Commission licence wherever the operator itself is based. A Curaçao, Maltese or Gibraltar licence is not a substitute for a Commission licence, and a brand that holds only an offshore licence is not licensed to take a GB customer’s bet.

The Commission’s public register is the whole test of whether a brand holds a licence. A reader who wants to verify a brand’s licence takes the account number from the brand’s own terms page and checks the register. The brands above carry account numbers in the comparison table precisely so a reader can do that check.

Betting licence categories

GB bookmakers hold one or more of five remote licence categories: general betting standard (real events), general betting standard (virtual events), general betting limited, pool betting, and betting intermediary. The brands in this set hold general betting standard (real events) licences; Smarkets also holds a betting intermediary licence as the exchange underneath the SBK sportsbook. A licence for one category does not cover another, which is why a betting exchange and a sportsbook can sit inside the same group as separate licences. Virtual events, esports, novelty markets and politics betting are offered by GB bookmakers under their own house rules rather than under any statutory list of permitted markets.

In-play, esports and novelty markets

GB bookmakers offer in-play betting on a wide range of sports, and the controls are the operator’s licence conditions and customer-protection duties rather than any statute on the markets themselves. There is no statutory prohibition on in-play on any particular sport, and there is no statutory cap on stakes in sports betting; operators set their own maximum stakes and may restrict customers. Esports are treated like any other event under the general betting standard (real events) licence, and bets on politics, TV shows and novelty events are offered by GB bookmakers without any statutory list restricting them. A reader who places a bet on a TV show at a GB-licensed bookmaker is betting under the operator’s licence, not under any separate statute on novelty markets.

The credit-card ban

Credit cards have been banned for gambling in Great Britain since 14 April 2020, and the ban covers credit-card-funded payments through an e-wallet as well as direct credit-card deposits. Debit cards and bank-based payments are not covered, and the welcome packages above reflect that: Coral and Unibet’s qualifying payment methods are debit cards and instant bank transfers because those are the methods the ban leaves open. Apple Pay and Google Pay are also accepted at most GB-licensed bookmakers, and Revolut Pay is now standard across the larger brands.

Identity verification before the first bet

GB-licensed bookmakers verify a customer’s name, address and date of birth before the customer can deposit or gamble, and the rule has applied since 7 May 2019. Verification runs even when the customer claims a free bet or a bonus, because the free bet is gambling under the Act. A customer who signs up at a GB-licensed brand, completes the document upload, and waits 24 to 48 hours for verification has paid the cost of being licensed; a customer who signs up at an offshore brand has skipped that cost but has also skipped the licence.

The financial vulnerability check

The Commission’s LCCP condition 3.4.4, in force since 30 August 2024 and tightened since 28 February 2025, requires a public-record check — for example, bankruptcy or county court judgments — on a customer whose deposits minus withdrawals exceed £150 in a rolling 30 days. The check is not an income check and not a credit reference check, and it is the lighter of the two Commission-mandated customer checks. The heavier check — a financial risk assessment, often called “affordability checks” in the press — has been announced by the Commission in a staged plan published on 7 July 2026, with no start date. A reader who sees a press article about “affordability checks” is reading about a rule that has been announced, staged and not yet in force.

Deposit limits, GAMSTOP and self-exclusion

GB-licensed bookmakers must offer customers a gross deposit limit on a fixed time frame under the Commission’s Remote Technical Standards, with the first phase in force since 31 October 2025 and a second phase postponed to 30 September 2026. Whether the second phase is currently live is not established in the published guidance, and a reader who sees a press article about “deposit limits” is reading about a system that has been partially implemented rather than fully in force. GAMSTOP is the national multi-operator online self-exclusion scheme and has been a mandatory licence condition for online operators since 31 March 2020. Exclusion periods are 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. GAMSTOP covers online sites and apps; betting shops use a separate self-exclusion service. Help for a customer who wants it sits with GamCare (the National Gambling Helpline), GambleAware, the NHS gambling clinics and Gamblers Anonymous.

Tax: who pays

The player pays no tax on betting winnings in Great Britain. General Betting Duty is the operator’s tax on gross profits, currently 15%; from 1 April 2027 a new remote betting rate of 25% applies within it, 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%. Until 1 April 2027 the remote rate stays at 15%, and whether operators pass duty on through odds is not established. Spread betting has its own rates (3% financial, 10% other), which is one reason the Spreadex homepage carries the warning that spread betting losses can exceed the deposit. A reader who treats the warning as marketing rather than as a real risk has misread the offer.

The offshore question

Providing gambling facilities in Great Britain without the licence the Act requires is an offence under section 33 of the Gambling Act 2005, and the offence is aimed at the operator, not the customer. The customer who places a bet at an unlicensed site does not commit an offence under the Act, but loses the protection that comes with a GB licence: no GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld, no application of the 10x bonus cap, no application of the £150 vulnerability check. The honest framing is licensed-or-not, not safe-or-not. A licensed site carries verification, limits and a bonus cap; an unlicensed site carries none of those protections and the risk of loss of funds.

How to check that a bookmaker is licensed

The check is short and worth doing before any welcome offer is claimed. Take the Gambling Commission account number from the brand’s own terms page and enter it into the Commission’s public register search. The result will confirm the licence category, the licence holder and the trading names covered by the licence. A licence for a single business name does not necessarily cover every trading name the parent company uses.

Two further checks are worth running. First, take the domain listed on the register and confirm it matches the domain the brand is using in the welcome offer; licensed operators use .com as well as .co.uk, so the domain alone proves nothing, but a mismatch between the brand’s domain and the registered domain is a flag. Second, take the parent company name from the register and confirm it matches the operator the brand’s own terms page names; several brands can run under one licensee (Ladbrokes and Coral under LC International Limited, Paddy Power and Betfair under PPB Counterparty Services), and a parent company that owns multiple trading names is not a reason to skip the licence check on the specific brand being used.

The Commission’s public register is updated continuously, and a brand that is licensed today can have its licence suspended or revoked tomorrow. The check is a snapshot, and a reader who values certainty re-runs the check before claiming any large welcome offer.

The responsible-gambling shelf, and how it meets the welcome offer

What every welcome offer is, and what it isn’t

A welcome offer is a commercial promotion that pays the customer a stake in exchange for the customer’s own stake at the start. It is not a refund, a price cut, or a guarantee; it is the price of admission to a licensed betting account, paid in free-bet form rather than in cash. A reader who treats the offer as the start of a relationship with a bookmaker is reading it correctly; a reader who treats it as a way to make money is reading it incorrectly. The bookmaker’s margin sits inside every price on the welcome offer, the qualifying bet and the free bet alike, and the headline figure is the size of the customer’s stake in the relationship rather than the size of the return.

The safer-gambling tools

GB-licensed bookmakers offer a set of safer-gambling tools as a condition of their licence: deposit limits on a fixed time frame, loss limits, time-out periods and GAMSTOP-registered self-exclusion. DAZN Bet’s published toolset is representative: deposit limits, loss limits and wagering limits, all settable inside the account. Every licensed brand above carries the same toolset under the same Commission rule, and the tools can be set before or after the welcome offer is claimed. A reader who sets a deposit limit at the start of the relationship has set the ceiling on the welcome package as well as on the rest of the betting; a reader who claims the welcome and sets the limit afterwards has set the ceiling on everything except the welcome they have already taken.

What to do if the welcome offer turns into something else

The welcome offer is, for most customers, the entry point. Some customers find that the entry point opens onto a longer road — and that the betting that started as a welcome-package-clearer has become something they would rather stop. The first stop is the safer-gambling tools inside the account: deposit limits, time-outs and self-exclusion. The second stop is GAMSTOP, which excludes the customer from every GB-licensed online operator for the chosen period. The third stop is GamCare, the National Gambling Helpline, which runs 24 hours a day on 0808 8020 133. GambleAware, the NHS gambling clinics and Gamblers Anonymous sit alongside GamCare as the other national help services, and all of them are free.

The customer who should not claim the offer

A welcome offer is not a free bet for a customer who cannot afford the qualifying leg. A £20 qualifying bet is not free to a customer whose budget does not stretch to a £20 loss; a £10 qualifying bet at minimum odds of 3.0 is not free to a customer who has to find a 2/1 selection just to qualify. The Commission’s safer-gambling tools exist precisely so a customer can set the ceiling on the welcome offer before claiming it, and a customer who reaches for those tools first has read the offer on its real terms. A customer who reaches for the offer first and the tools afterwards has read it the other way round, and the cost of the welcome is whatever the qualifying leg costs them.

What the welcome offer doesn’t cover

The markets, the in-play book and the live streams

A welcome offer pays a stake; it does not pay for the markets, the in-play book or the live streams that sit underneath. bet365’s Bet Builder+ and Super Boosts, Unibet’s live TV and Best Odds Guaranteed on horse racing, Sky Bet’s Super Boosts feed, Spreadex’s Acca Boosts, Kwiff’s Supercharge feature on instant odds boosts, BoyleSports’ Acca Insurance and Acca Loyalty — none of these are part of the welcome package, and none of them are unlocked by claiming it. They are the product the welcome pays the customer to try, and a customer who values one of them should weigh the welcome against the product rather than against the headline alone.

The payment methods

Coral and Unibet’s debit-card-or-instant-bank-transfer requirement is one of two payment-method restrictions in this set; the other is the credit-card ban that applies to every GB-licensed brand. A customer who funds with Apple Pay or Revolut Pay at Coral or Unibet will not clear the welcome; a customer who funds with a credit card at any GB-licensed brand will not clear the welcome anywhere. The restrictions reflect the credit-card ban and the qualifying-method rules, not any judgment about the customer’s payment choice. A customer who wants the welcome paid through a different method has to choose a brand whose terms do not restrict the qualifying payment.

The exchanges and the spread book

Smarkets’ SBK sportsbook is the only betting exchange sportsbook in this set, and Spreadex is the only spread-betting book. A welcome offer at an exchange sportsbook pays the customer to bet into a different product than a traditional sportsbook, and a welcome offer at a spread-betting firm pays the customer to bet into a market where losses can exceed the deposit. Neither offer is wrong for the right customer; both offers are wrong for the customer who has not read past the headline.

FAQ

How does someone sign up with a betting site in Great Britain?

Sign-up at a GB-licensed bookmaker requires a name, address, date of birth and a payment method; the operator verifies the identity before the customer can deposit or gamble, and the verification has run on every licensed brand since 7 May 2019. A customer who claims a welcome offer before verification will not have the free bets credited until the verification clears, which usually takes 24 to 48 hours.

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

The Commission’s promotion rules in force since 19 January 2026 cap the wagering multiple on a bonus at 10x: a £10 bonus can demand no more than £100 of qualifying bets, and a £100 bonus no more than £1,000. The cap does not apply to free bets with no wagering condition, which most welcome offers in this set carry, but it is the backstop on any reload or deposit-match bonus the customer meets.

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

The minimum odds clause tells the customer what kind of selection the qualifying bet has to be — 1/1 (2.0) at Sky Bet and Coral, 3.0 (2/1) at SBK. The wagering requirement tells the customer how many times the bonus must be turned over before it is withdrawable, capped at 10x since 19 January 2026. The two clauses together determine the cost of clearing the offer.

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

A free bet pays winnings only. A £10 free bet at 5.0 returns £40 in profit on a win, not £50; the £10 stake is the operator’s cost of the offer. This is the standard structure at GB-licensed bookmakers and the one most likely to be missed by a reader who treats the offer as cash.

Can a bet on sport be tied to a casino bonus under the Commission’s promotion rules?

No. The mixed-product ban that took effect on 19 January 2026 prohibits any offer that requires gambling on two or more product types — sports betting tied to casino, sports betting tied to bingo, a sportsbook bonus that hands out free spins. Any licensed GB bookmaker running such an offer would be in breach of the Commission’s promotion rules.

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

Take the Gambling Commission account number from the brand’s own terms page and enter it into the Commission’s public register. The check is the whole test of whether a brand is licensed, and it is worth running before any welcome offer is claimed.
