A welcome offer is the price a bookmaker pays to acquire a customer. In Great Britain that price is now shaped by the Gambling Commission’s promotion rules in force since 19 January 2026 — wagering requirements on bonuses are capped at ten times the bonus amount, and an offer that requires gambling on two or more product types (a free bet that only unlocks after a casino turn, for instance) is no longer permitted. What sits beneath those rules is a set of ordinary free bets, mostly in the £10-to-£60 range, paired with qualifying-bet terms that quietly cost more than the marketing lets on. This page reads them for what they pay out.

The UK welcome-bonus market at a glance

Ten licensed bookmakers form the comparison below. Before the rankings, a short tour of what the market actually looks like — what the offer shapes are, where the prize money sits, and where the operator’s terms bite. The single most useful number on this page is the difference between a £30 free bet whose stake is returned on a win and a £30 free bet whose stake is not. Most free bets in this country are the second kind, and the second kind is worth materially less than the figure on the page.

Midnite's site cites Gambling Commission licence 101839 and shows in-play events, an acca builder, popular accas and price boosts with maximum-stake limits.

Most of these brands pair the headline free bet with one of three quieter mechanisms: a price boost on a chosen event (Paddy Power’s “Power Prices” or Betfair’s “Odds Boost”, say), a stake-back insurance on an accumulator, or a loyalty credit that drops after the qualifying bet has settled. The headline number is what the reader sees; the rule is what determines what they walk away with. Coral’s £40 in free bets for a £20 qualifying bet at minimum odds of 2.0 reads one way before you check that the seven-day expiry starts the moment the free bet lands in the account, and quite another afterwards.

The wagering cap in force since 19 January 2026 changes the texture of the smaller end of the market. A bonus of £10 with a 50x requirement — common enough in casino products — would have asked for £500 of qualifying turnover; the cap reduces that to £100. On the betting side, where the wagering factors are typically lower and many free bets carry no wagering condition at all, the cap is more of a backstop than a daily concern. The change that lands harder on this list is the ban on mixed-product promotions: offers that asked a customer to bet on football to unlock casino spins, or vice versa, are now off the table.

The size of these offers clusters more than people expect. Eight of the ten brands reviewed below sit in a £10-to-£60 band; the outliers above that figure are mostly chains of small free bets rather than a single larger one. The marketing word is “free” — the regulated word is “free bet”, and the difference between the two is that a free bet does not return its stake with a win.

How the top ten compare

A single table pulls together the licence number each operator holds against the Gambling Commission’s public register and the headline welcome offer as that operator’s own terms state it. The order is not a ranking of offer value — the value question is in the write-ups that follow.

Octobet 62545 (Octopus Game Limited) 50% back as a free bet up to £50, plus a £10 casino bonus

DAZN Bet 48756 (DZBT Limited) Cash Out, Bet Builder, daily bet boosts, in-play; safer-gambling tools include deposit, loss and wagering limits

The licence numbers above are account numbers on the Commission’s public register, each linked to a category of remote betting licence held by the named operator. The right-hand column pulls the headline offer from that operator’s own published terms on 16 October 2026 — date-stamped so the reader knows what was live when this comparison was made.

Coral — £40 in free bets for a £20 qualifying bet

Coral’s welcome offer is the form most UK bookmakers copy in some shape: a £20 qualifying bet at minimum odds of 2.0 (1/1) returns £40 in free bets, credited within seven days and expiring seven days after issue. The qualifying deposit and bet must use a debit card or instant bank transfer — credit cards have been banned for gambling in Great Britain since 14 April 2020, and Coral’s included list (Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport, Trustly) reflects what that constraint leaves. The free bets themselves can be used on most markets; the expiry is the cost the headline number hides.

The brand sits inside the Ladbrokes-Coral group under LC International Limited, so its licence and that of its sister sites trace back to the same Commission account. On the product side, Coral runs a daily free Reward Shaker, an Odds Booster across hundreds of markets and the free-to-play Football Super Series with a £10,000 jackpot — modest recurring value that the headline offer does not include but that does exist on the account.

Verdict. A standard shape and a clear expiry. The £40 in free bets is the largest single free-bet token in this comparison, and the seven-day expiry is the tightest in the table.

Spreadex — £60 in free bets for a £10 fixed-odds bet

Spreadex runs two products under one account: fixed-odds sports betting, regulated by the Gambling Commission, and financial spread betting, regulated by the Financial Conduct Authority. The £60 in free bets is for a fixed-odds bet of £10 or more at minimum odds of 1/2, with the qualifying bet to be placed within 28 days of opening the account; the free bets can be used across fixed odds and spread betting, which is unusual. The 28-day window on the qualifying bet is more generous than most; the offer is also the largest single headline figure here.

The two regulators are worth noting. A punter who moves from the fixed-odds side to the spread-betting side is now on a different legal footing, and spread-betting losses can exceed the deposit — Spreadex’s own homepage says so. That is the trade for the bigger free-bet figure: the brand offers something genuinely different, and the customer who uses both sides takes on a different kind of risk.

The Acca Boost on football accumulators of three or more selections pays a cash boost from 5% to 100% depending on the leg count, on top of the headline welcome offer. That is recurring value, not a one-off.

Verdict. Largest single free-bet figure in this comparison, paired with the longest qualifying window. The spread-betting side is a different product under a different regulator; readers who stay on fixed odds get the cleanest deal.

William Hill — Football Acca Boost up to 200% on twenty or more legs

William Hill’s headline offer is not a free-bet token at all. It is the Football Acca Boost, which adds a percentage boost to the winnings of a football accumulator of two or more legs, each at 1/5 (1.20) or bigger, scaling from 3% on a double up to 200% on twenty or more selections. The maximum boost is £10,000 per online bet, and the promotion runs until 30 May 2027. For a customer who already bets football accumulators, this is recurring value rather than a one-off welcome credit — and the running date gives the promotion a long tail.

The licence is held by WHG (International) Limited under Commission account 39225, the same operator that runs several other UK-facing brands in this market. William Hill also runs Best Odds Guaranteed on horse racing and a depth of in-play markets that bigger accumulators tend to need.

Verdict. The offer rewards a habit rather than acquiring one. A reader who already backs football accas at the required leg counts gets more here than from a single free-bet token; a reader who bets singles and doubles will see little of the value.

Fitzdares — premium pricing, fast Visa withdrawals

Fitzdares does not publish a sports welcome free-bet token in the materials reviewed for this comparison; what its materials do state is the payment profile. Apple Pay, Mastercard and Visa are accepted; Visa withdrawals are usually same-day, while Mastercard withdrawals can take up to 48 hours. For a customer whose priority is moving winnings back to a bank account quickly, that is a concrete answer to a concrete question, and it is a different category from a free-bet headline.

The licence is held by Fitzdares Limited under Commission account 400 — the lowest account number on this list, and not a ranking signal, but a marker of how long the brand has been on the register. Best Odds Guaranteed on horse racing and a depth of in-play markets are typical of a UK-facing sportsbook.

Verdict. A sportsbook priced for a different reader than the rest of this list. The withdrawal times are the concrete answer; the absence of a headline sports welcome offer means a customer comparing offers should look at what is paid in cash rather than what is paid in free bets.

Betboro — 100% matched free bet up to £25

Betboro’s headline offer is a 100% matched free bet of up to £25 on the first qualifying wager, requiring a debit card deposit of at least £10 and a first bet of £5 to £25 with at least three selections each at 3/5 (1.60) or higher. The matched free bet is the largest proportional offer in this comparison — stake £25 on a first qualifying wager and the brand matches it back as a free bet — and the three-selection minimum on the qualifier is the price of that generosity.

The licence is held by Webmedia Development N.V. under Commission account 44181, an overseas operating company running a UK-facing remote licence. The brand’s product depth, market breadth and live-streaming coverage are less well documented than the longer-established names here; that is the other side of the offer.

Verdict. A generous headline matched to a multi-leg qualifier. A reader who would have bet an accumulator anyway gets the full value; a reader who would have bet a single pays for the bonus in the qualifier they did not want.

VBet — £10 free bet if the first £10 bet loses

VBet’s welcome offer is the simplest on the list, and the most easily mis-sold. A new, verified customer who stakes £10 or more on a first-ever bet receives a £10 free bet if that bet loses. It is, in industry language, a “losing bet” refund — the qualifier runs the full risk of a normal bet, and the refund arrives only as a free bet whose stake is not returned on a win. Read as “free £10”, it is not free; read as insurance on a first bet, it is exactly what it says.

The licence is held by SCGO Limited under Commission account 44662. VBet also offers a depth of in-play markets across football, tennis and basketball; that product breadth sits below the welcome offer, not inside it.

Verdict. Insurance on a first bet, marketed as a free bet. The refund is in free-bet tokens, not cash, and the qualifying bet is at full risk. A reader who reads the offer as “£10 free for signing up” will be disappointed.

BetGoodwin — £15 in free bets across three products for a £10 qualifying bet

BetGoodwin’s £15 in free bets for a £10 qualifying bet is split across three £5 tokens: a £5 sports bet, a £5 acca and a £5 Sub-Cover bet. The split is unusual — most offers on this list give a single token — and it rewards a customer who uses all three products. The £5 Sub-Cover is a horse-racing product (a substitute-runner cover), and it is the differentiator on this offer.

The licence is held by Goodwin Racing Limited under Commission account 2927. The brand sits in the smaller end of the UK sportsbook market; its account number is also the lowest of the ten listed here.

Verdict. A three-part welcome offer that rewards a horse-racing customer. A punter who bets accas and singles as well as horses gets the full £15; a punter who bets only football sees only the £5 sports token.

Octobet — 50% back as a free bet up to £50, plus a £10 casino bonus

Octobet’s sportsbook welcome is the headline 50% back as a free bet up to £50 — stake £100, get £50 back as a free bet if the bet loses — paired with a £10 casino bonus for new customers. Under the Commission’s 19 January 2026 rules, mixed-product promotions are banned, so the combined offer structure here reflects the period before those rules took full effect; whether the casino portion remains live on Octobet’s terms at any given date is a question for the reader to check on the brand’s own page.

The licence is held by Octopus Game Limited under Commission account 62545. The brand sits in the newer end of the UK sportsbook market, with a sportsbook product depth that is less established than the longer-running names on this list.

Verdict. A back-half-of-stake refund with a casino tail. The headline is generous, and the casino portion is the line a reader needs to verify against Octobet’s current terms before claiming.

Betmaster — live in-play and Cash Out, no sports welcome offer reported

Betmaster’s materials on the GB-facing site do not report a sports welcome offer in the form reviewed for this comparison. What the brand does report is a live in-play sportsbook with Cash Out, a Bet Builder, and a range of markets — product features rather than welcome credits. The licence is held by BM Solutions GB Ltd, registered in Malta, under Commission account 65699.

That is a real shape on this market. Not every licensed brand runs a headline welcome offer; some compete on product features and on recurring promotions rather than on the acquisition credit. A reader comparing welcome offers will see no value, and a reader comparing in-play markets and Cash Out availability may see a different answer.

Verdict. A sportsbook without a headline welcome token, competing on product features. A reader whose decision turns on the welcome offer alone should look elsewhere on this list; a reader whose decision turns on in-play product depth should look at the Betmaster platform.

DAZN Bet — Cash Out, Bet Builder, daily bet boosts, in-play. DAZN Bet’s product set is Bet Builder, Cash Out, daily bet boosts and an in-play book — the four pillars of a modern UK sportsbook, marketed together rather than as a welcome offer. Cash Out is a feature whose availability is not guaranteed; the operator’s own terms state that bets stand if Cash Out is unavailable at the moment a customer tries to use it. That is the rule that turns a marketed feature into a real product: the customer does not have a guaranteed right to cash out, only the right to bet on a market where cash out may be offered.

The safer-gambling toolkit is the concrete product on the page. DAZN Bet offers deposit limits, loss limits and wagering limits as account controls — three separate levers, set by the customer against their own spend. The licence is held by DZBT Limited under Commission account 48756.

Verdict. A sportsbook competing on product and on safer-gambling tools rather than on a headline welcome offer. A reader who values Cash Out and Bet Builder availability has a shortlist that includes DAZN Bet; a reader who values a headline free bet has nine other names to look at first.

How the welcome offer actually pays out

The arithmetic on this page is the bonus-turnover calculation: what does it cost a customer, in qualifying bets, to clear the wagering requirement on a welcome offer, and how many bets does that take at a typical stake? The wagering cap of 10x in force since 19 January 2026 sets the ceiling. The example below uses Coral’s £40 in free bets offer; the inputs are research’s fact bank, and the same arithmetic applies to any offer on this list once the bonus base and wagering multiple are substituted.

The inputs. A bonus base of £20 (the qualifying bet that triggers the £40 in free bets at Coral) at a wagering factor of 1x — free bets whose stake is not returned with a win carry no wagering factor in the strict sense, and Coral’s offer does not impose turnover on the free-bet tokens themselves. The 10x cap is the ceiling that applies to any bonus with a wagering factor; under that cap a £20 bonus with a 1x requirement asks for £20 of qualifying turnover. At a stake of £5 per qualifying bet, that is four bets. At a minimum odds requirement of 2.0 (1/1) on the free-bet token, only bets at or above that price count.

The result. Between £20 and £100 of qualifying turnover to clear the wagering requirement on a £20 bonus, depending on whether the offer carries a 1x, 2x, 5x or 10x factor. At a £5 stake and a 1x factor, four bets at minimum odds of 2.0 clear the requirement; at a 10x factor, forty bets. The condition that determines the band is the wagering factor the offer’s own terms state.

The key assumption. The arithmetic assumes only the bonus amount is being wagered (no deposit-plus-bonus base), the qualifying stake is £5 per bet, and every bet is placed at the minimum odds the terms require. A customer who places larger or shorter-priced bets will arrive at a different figure in absolute terms; the count of bets is the constant.

A free bet whose stake is not returned with a win is worth less than its face value on average. A £30 free bet at odds of 3.0 (2/1), with the stake not returned, returns £60 in profit on a win, not £90; the expected value depends on the probability of winning at those odds and the margin of the market, and that expected value is what the offer is really worth in cash terms. The headline figure is not the cash figure.

The wagering cap changes the smaller end of this market. A £10 bonus with a 50x requirement would have asked for £500 of qualifying turnover; the 10x cap reduces that to £100. The casino side of the industry is where the cap bites hardest. On the betting side, where most offers carry no wagering condition or a low one, the cap is a backstop.

Bonus shapes and what they actually mean

The free bet is the central object on this page, and the wagering requirement is the rule that determines its cost. The wagering requirement is the number of times the bonus amount must be turned over in qualifying bets before any winnings become withdrawable. A 1x requirement on a £20 bonus asks for £20 of qualifying bets; a 10x requirement on a £20 bonus asks for £200 of qualifying bets. The minimum odds requirement is the floor: bets placed at odds below the stated minimum do not count toward the turnover, even if they win. The expiry is the deadline, and a seven-day expiry is shorter than most readers realise when they sign up.

The stake-not-returned rule is the single most expensive clause on this page. Most free bets in this comparison are stake-not-returned — a £40 free bet at odds of 3.0 returns £80 in profit on a win, not £120. The rule is so common that it appears in nearly every operator’s own terms; it is also the rule that turns a £30 free bet into an offer worth, in expected cash terms, somewhere between £15 and £25 depending on the market. The headline figure is the marketing figure; the cash figure is the real one.

The minimum deposit is the cheapest part of the offer to clear. A £5 deposit at Sky Bet, a £5 bet at Betboro, a £10 deposit at Coral — the qualifying deposit is the smallest commitment in any of these offers. The cost is not the deposit; it is the qualifying bet at minimum odds, the wagering requirement on the bonus, and the expiry on the free-bet tokens.

The mixed-product ban in force since 19 January 2026 is the change to read carefully. An offer that asks a customer to bet on football to unlock casino spins — or to wager casino winnings on a sportsbook — is no longer permitted under the Commission’s promotion rules. Any offer on this list that carries a casino tail, like Octobet’s £10 casino bonus, reflects the period before those rules took full effect; the current state of any individual offer is something the reader checks on the operator’s own terms.

The rules a UK welcome offer has to follow

The Gambling Commission’s promotion rules in force since 19 January 2026 set two outer edges on every welcome offer a UK-licensed bookmaker can run. The first is the 10x wagering cap: no bonus can carry a wagering requirement above ten times the bonus amount. The second is the mixed-product ban: no offer can require a customer to gamble on two or more product types — betting, casino, bingo, lottery — to unlock the bonus. Both rules apply to all gaming the Commission licences, and both are enforced through the Licence Conditions and Codes of Practice that operators agree to as a condition of holding a licence.

The credit-card ban in force since 14 April 2020 is the third rule a welcome offer has to clear. No credit card, and no credit-card-funded e-wallet payment, can fund a gambling deposit at a UK-licensed operator; the qualifying deposit and bet on most of the offers in this comparison must use a debit card or a bank-based payment method. The ban is operational, not just on the offer: it is enforced at the cashier.

The minimum-age rule (18) and the identity-verification rule (since 7 May 2019) mean there is no anonymous play at a UK-licensed site. Name, address and date of birth are verified before the first deposit or bet, including a free bet or bonus. The verification is part of the price of being licensed.

The advertising rules that surround these offers are run by the Advertising Standards Authority under the CAP Code, not by the Commission. CAP Code section 16 covers gambling specifically: marketing must be socially responsible, must not strongly appeal to under-18s, and no one who is or seems to be under 25 may be featured gambling in an advertisement. The rules cover who may appear in the ad; they do not change who may bet.

Responsible gambling at UK-licensed bookmakers

Every operator on this list is a member of GAMSTOP, the national multi-operator online self-exclusion scheme that has been a mandatory licence condition for online operators since 31 March 2020. Self-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; betting shops use a separate multi-operator self-exclusion service. Registering with GAMSTOP is the single most effective step a customer who wants to stop betting online can take.

Deposit limits are the customer-set ceiling on what they can fund their account with. The Commission’s Remote Technical Standards (RTS 12) require operators to offer a gross deposit limit on a fixed time frame; the first changes have applied since 31 October 2025, a second phase was postponed to 30 September 2026, and whether that second phase is live on a given date is something to check on the operator’s own page. There is no state-set ceiling on deposits or losses at a UK sportsbook: the limit is the customer’s choice, set on their own account.

The financial vulnerability check is the third safeguard. Since 28 February 2025 it applies when a customer’s deposits minus withdrawals exceed £150 in a rolling 30-day period: it is a public-record check (bankruptcy, county court judgments) rather than an income check or a credit-reference check. Financial risk assessments — the affordability checks of the press coverage — are announced in a staged plan with no start date; the public framing from the Commission is “announced, staged, no start date”, not “in force”.

GamCare runs the National Gambling Helpline, GambleAware funds treatment and education, the NHS runs gambling clinics in parts of England, and Gamblers Anonymous runs peer-support meetings across the country. None of those is an operator; none of them takes a cut of the customer’s stake. That is what makes them a separate category from the safer-gambling tools on a licensed operator’s own page.

The Gambling Commission licences the whole commercial market under the Gambling Act 2005, which covers Great Britain — England, Scotland and Wales. Northern Ireland sits outside the 2005 Act and is governed by its own older law; a GB licence does not extend there. 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 operating licence is not a substitute for a GB licence. The Commission’s public register — searchable by business name, trading name, domain or account number — is the whole test of whether a brand holds a GB licence; if a brand is not on the register, it is not licensed in Great Britain, and the 10x bonus cap, the credit-card ban and the GAMSTOP membership that follow from a licence do not apply to it.

The licence categories matter. A remote general betting standard (real events) licence covers sports betting on real events; a remote general betting standard (virtual events) licence covers computer-generated events; a remote general betting limited licence is a smaller category; a remote pool betting licence covers pool betting on horse and dog racing; a remote betting intermediary licence covers betting exchanges. A casino licence is a separate category, and a casino welcome bonus is governed by the casino rules, not the sportsbook rules. The bookmakers on this list all hold a remote general betting standard (real events) licence; some also hold casino or pool betting licences as additional categories.

Financial spread betting is regulated by the Financial Conduct Authority, not the Commission. Spreadex runs both products under one brand — fixed-odds sports betting under the Commission, financial spread betting under the FCA — and the FCA’s regime is the different one. Spread-betting losses can exceed deposits, which is not the case for fixed-odds betting. The brand’s own homepage states this.

Betting duty is the operator’s tax, not the customer’s. General Betting Duty is currently 15% on the operator’s gross profits from general betting; 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, pool betting and in-person betting stay at 15%. The customer pays no tax on betting winnings in Great Britain — a general statement, not tax advice; a professional gambler should ask HMRC or an adviser. Whether operators pass duty on through odds is not established, and a reader should never see a statement that the duty is charged to the player.

What an unlicensed site costs a customer

A bookmaker whose facilities are used in Great Britain without a Commission licence commits an offence under section 33 of the Gambling Act 2005 — the offence is aimed at the operator, not the customer. The penalty on summary conviction is up to 51 weeks’ imprisonment, a fine up to level 5, or both (six months in Scotland). No offence aimed at a customer who bets on an unlicensed site has been found in the materials reviewed; the framing for a customer is loss of protection rather than criminal liability.

Loss of protection is the concrete cost. No GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld. The 10x bonus cap, the £150 financial vulnerability check, the credit-card ban and the mandatory safer-gambling tools do not apply. The customer is playing under the operator’s own house rules and the operator’s own jurisdiction.

Enforcement against unlicensed operators is disruption, not blocking: cease-and-desist notices, search-engine referrals, work with registrars, hosts and payment providers. The Commission has been given, or is about to receive, court-order DNS blocking powers; ISP blocking is not yet in operation as a general measure, and that framing should not be written as if it is. The legal line is that a GB licence is compulsory at the point of consumption and that the offshore alternative trades British consumer protection for whatever the operator chooses to offer.

Reading the small print on a welcome offer

Three clauses sit on nearly every UK welcome offer, and each is worth reading before a customer claims. The first is the expiry: a seven-day expiry on a £40 free bet is a real deadline, and the tokens expire at the end of the seventh day whether or not the customer has used them. The second is the stake-not-returned rule: a free bet that wins returns the winnings only, not the free-bet stake. The third is the minimum odds requirement on the qualifying bet: a £20 qualifying bet at minimum odds of 2.0 must be placed at 2.0 or higher; a bet placed at 1.8 does not qualify.

The wagering requirement on the bonus is the fourth clause where it applies. Free bets whose stake is not returned with a win usually carry no wagering factor on the free-bet tokens themselves; the wagering factor that exists is on the qualifying deposit (rare on sportsbook offers, common on casino bonuses). The Commission’s 10x cap applies to the wagering factor on any bonus — the cap is the ceiling on the requirement, and any offer that asks for more is not permitted at a UK-licensed operator.

The mixed-product structure is the fifth clause to read. An offer that asks a customer to bet on sports to unlock casino spins, or vice versa, is no longer permitted under the 19 January 2026 promotion rules. Any welcome offer that carries a casino tail — Octobet’s £10 casino bonus is the example here — should be checked against the operator’s current terms, since the live state of any mixed-product offer is something that changes as the rules bed in.

The payment-method restriction is the sixth clause. A welcome offer that must be qualified with a debit card or instant bank transfer is the standard shape on this list; credit cards are not an option. Apple Pay, Google Pay, Revolut Pay and bank-based methods like Trustly, TrueLayer and Earthport are the alternative routes most of these operators publish.

How this comparison was put together

The data on this page was reviewed on 30 October 2026 against two sources. The first is the Gambling Commission’s public register, where each licence number and category was verified against the trading name and the operating company on the register. The second is each operator’s own published terms on the same date — welcome-offer pages, terms and conditions, customer-help pages and the App Store descriptions of the GB-facing mobile apps — which is where the welcome-offer shape, the wagering factor, the minimum odds, the expiry and the payment methods come from.

The licence numbers in the comparison table are account numbers on the register, each linked to a remote general betting standard (real events) licence held by the operating company named in the row. The table is a snapshot, not a permanent record: a licence can be surrendered, varied or have conditions changed at any time, and the register is the live source. A reader who needs the live state of a licence checks the register directly.

The welcome-offer descriptions are taken from the operator’s own terms on 16 October 2026, with the caveat that offers change, that opt-in is usually required, and that the qualifying bet’s minimum stake, minimum odds and expiry are the small print the headline figure leaves out. The arithmetic on the calculation section is the bonus-turnover calculation the plan names, applied to Coral’s offer as the worked example.

Frequently asked questions about UK betting welcome bonuses

How do I claim a welcome bonus at a UK bookmaker?

Sign up with the brand, complete the identity verification the Gambling Commission requires (name, address, date of birth — usually automated, sometimes with a document check), make the qualifying deposit through a debit card or bank-based method the operator accepts, place the qualifying bet at the minimum stake and minimum odds the offer’s terms state, and accept the free-bet tokens or bonus credit when they land in the account.

Every brand on this list except Betmaster and DAZN Bet publishes a sports welcome free-bet token in the materials reviewed here; Betmaster and DAZN Bet compete on product features (Bet Builder, Cash Out, in-play) rather than on a headline welcome credit. The brands with a headline free-bet token are Coral, Spreadex, William Hill, Fitzdares (payment profile only), Betboro, VBet, BetGoodwin and Octobet. Each of those tokens carries its own stake-not-returned rule, its own expiry and its own minimum odds requirement.

Which UK betting site has the largest welcome bonus?

Spreadex’s £60 in free bets for a £10 fixed-odds bet is the largest single headline figure in this comparison, paired with the longest qualifying window (28 days). Coral’s £40 in free bets for a £20 qualifying bet is the second-largest single token; BetGoodwin’s £15 split across three tokens is the most fragmented. Cash value depends on the stake-not-returned rule and the minimum odds the free-bet tokens carry, so the headline figure is not the cash figure.

What is the maximum wagering requirement on a UK betting bonus?

Ten times the bonus amount, under the Commission’s promotion rules in force since 19 January 2026. A £20 bonus with a 10x wagering requirement asks for £200 of qualifying turnover; the cap is the ceiling on the requirement, and any bonus that asks for more is not permitted at a UK-licensed operator. Free bets whose stake is not returned with a win typically carry no wagering factor on the free-bet tokens themselves, in which case the cap is a backstop rather than a daily concern.

What do minimum odds and the wagering requirement mean on a welcome offer?

The minimum odds requirement is the floor on the price of a qualifying bet: a bet placed below the minimum does not count toward the offer, even if it wins. The wagering requirement is the number of times the bonus amount must be turned over in qualifying bets before the winnings become withdrawable. A £20 bonus with a 1x requirement asks for £20 of qualifying turnover; a 10x requirement on the same bonus asks for £200. Bets placed below the minimum odds do not count toward either figure.

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

Because that is the industry standard definition of a free bet at UK-licensed operators, and the headline figure is the face value of the token, not the cash it pays out on a win. A £30 free bet at odds of 3.0 returns £60 in profit on a win, not £90. The expected cash value of a stake-not-returned free bet depends on the probability of winning and the margin of the market the token is used on; the headline figure is the marketing figure, and the cash figure is what walks out of the account.
