Every major GB bookmaker offers a headline figure the moment a new account is opened. Some give £40 in free bets for a £20 opening wager, others push a 100% matched free bet to £25, and one returns half of the first stake as a free bet if it loses. The number on the landing page is not the figure that counts, because three rules apply to every one of them and they change the math before a bettor has placed a single qualifying punt. A bonus is a loan from the bookmaker, not a gift, and the loan is paid back through wagering, time and minimum-price conditions.

The welcome bonus market in Great Britain has tightened since the Gambling Commission’s new social responsibility code took effect on 19 January 2026. Wagering requirements on bonuses are now capped at 10x, and a promotion that demands gambling on more than one product type — an offer that asks for a sports bet to unlock free spins, for instance — is no longer allowed at any GB-licensed brand. That cap is the single most useful number to keep in view when comparing offers: a £10 bonus with a 10x wagering requirement means £100 of qualifying bets before withdrawal, where the same bonus on the old 50x terms would have meant £500.

Below is a working comparison of ten GB-licensed bookmakers, drawn from the Commission’s public register and from each operator’s own current terms. The aim is not a ranking. Welcome bonuses are not the same shape across brands — some pay back a fixed sum of free bets, others match the opening stake, others give half the loss back as a credit. What matters is which model suits which bettor, and how much of the headline figure actually ends up in the pocket after the terms are read.

How the GB welcome bonus market actually works

The shape of an offer in 2026

A welcome offer is a package, not a payment. It typically consists of three parts: a qualifying action the new customer has to take, a free-bet or bonus-credit reward, and a set of withdrawal conditions on that reward. Each part has a cost, and the cost is usually written in small type at the bottom of the promotion page.

The qualifying action is almost always a first deposit combined with a first bet. William Hill’s acca insurance is not a welcome offer, but the same rule applies elsewhere. Free bets are credited only after the qualifying bet has settled, which means the very first stake a customer places has to be real money, not a bonus. The qualifying bet carries its own minimum odds — Coral demands evens (2.0), Spreadex 1/2 (1.50), Betboro three selections each at 3/5 (1.60) or higher. A bet that fails the minimum-odds test does not trigger the free bet, even if it wins.

The reward usually arrives within forty-eight hours and is paid in free bets, not cash. Free bets cannot be withdrawn directly. They have to be turned into real winnings by being wagered, settled, and only then is any profit withdrawable. The reward has an expiry. Coral gives seven days, Unibet gives seven days, QuinnBet’s free bets are valid for seven days from credit, and Spreadex asks that the qualifying fixed-odds bet be placed within twenty-eight days. A free bet that expires before it is used is worth zero.

Wagering requirements and the new 10x cap

The wagering requirement is the key figure that decides how much betting the offer actually takes. It is the multiplier that determines how many times the bonus, and sometimes the bonus plus the deposit, must be turned over in qualifying bets before any withdrawal is allowed.

Before 19 January 2026 a 50x wagering multiplier on a £10 bonus meant £500 of bets at minimum odds before a withdrawal. That kind of requirement was not unusual. The new social responsibility code in force since that date places a hard ceiling on the bonus side: wagering requirements on bonuses are capped at 10x. A £10 bonus at 10x means £100 of qualifying bets. A £100 bonus at 10x means £1,000. The cap stops the most punishing multiplier game, but it does not remove wagering requirements altogether — it just bounds them.

The cap does not apply to free bets without a wagering condition, and the Commission has not yet published its position on that case. Reading the offer carefully still matters. A free bet of £30 with a 5x wagering requirement is different from one with no wagering condition at all, and the second is rarer than the marketing suggests.

Minimum odds and the “qualifying bet” trap

Minimum odds serve two purposes for the bookmaker. They weed out bets that the customer would have placed anyway, and they push the customer into prices with a fatter margin. A minimum-odds rule of 1/2 (1.50) allows bets on most single favourites but excludes the most likely winners. A rule of evens (2.0) or 3.0 is tighter still.

Spreadex requires minimum odds of 1/2 (1.50) on the qualifying fixed-odds bet. Coral and Unibet both demand 2.0, which is a higher threshold: an evens shot has roughly a 50% chance of winning, so a customer whose only interest is unwinding the bonus has to pick a price the bookmaker considers genuinely uncertain. Betboro goes further and asks for at least three selections, each at 3/5 or higher, so the qualifying bet has to be a small accumulator.

Bets placed below the minimum, even if they win, do not count toward the wagering requirement and may even void the offer altogether. Several operators reserve the right to withdraw the free-bet reward if the qualifying bet is suspicious — that is, a bet laid purely to unlock the bonus. The honest framework is to assume the qualifying bet will be settled first, the free bet credited on that settlement, and the rest of the offer played out only after.

Expiry and the deadline that quietly eats bonuses

A free bet that expires is worth nothing. Coral, Unibet and QuinnBet all give seven days from issue. The clock starts the moment the credit lands in the account, and any free bet still sitting unused at the deadline disappears with the winnings it would have generated.

Account-level expiry is different from bonus-level expiry. Spreadex gives twenty-eight days from account opening to place the qualifying bet — the bet itself can settle at any point, but if it has not been placed inside the window the welcome offer is closed out entirely. That distinction is the single commonest reason welcome bonuses are lost without trace: the customer registers, plans to bet on Saturday’s fixture, and the twenty-eight-day window closes on a Wednesday nobody was watching.

What is and is not paid back

Free bets split into two families. The first returns the stake along with the winnings, so a £10 free bet at odds of 4.0 pays back £40 if it wins — £10 of stake plus £30 of profit. The second does not return the stake, so that same bet pays back £30 of profit only.

The second family is the one UK bookmakers use. A free bet’s stake is usually not paid back with the winnings, and this is the most underappreciated variable in a welcome offer’s value. A £30 free bet at fractional odds of 2/1 wins £60 of profit, not £90, and the difference — the missing £30 — is real money the customer gave up by accepting the form of the offer. The marketing headline cannot tell you which family the bonus belongs to. The site’s terms — usually a sentence beginning “stake not returned” or “free bet winnings only” — is where the answer lives.

The legal frame every GB welcome bonus sits inside

The Gambling Commission and remote licences

Every brand on the comparison below holds a remote operating licence from the Gambling Commission. The Commission is the regulator for gambling in Great Britain, sponsored by the Department for Culture, Media and Sport, and the licences are issued under the Gambling Act 2005. A separate Act, the Gambling (Licensing and Advertising) Act 2014, removed the previous offshore exemption: an operator whose remote facilities are used in Great Britain needs a Commission licence wherever it is based. A Curaçao or Malta licence is not a substitute.

The Commission’s public register can be searched by business name, trading name, domain or licence account number, and it is the only reliable test of whether a brand is licensed. Several large UK names operate under the same parent licence — Ladbrokes and Coral share LC International, Paddy Power and Betfair share Flutter — so the licence number on the register does not always match the brand name on the website. Domains prove nothing: a .com address is fine, a .co.uk address does not imply a licence. Checking the brand against the register is the check; the URL is decoration.

Identification before a bet

Every customer at a GB-licensed remote bookmaker has name, address and date of birth verified before they can deposit or gamble. The rule has been in force since 7 May 2019, covers even a first bet made with a free bet or bonus, and there is no anonymous play at a licensed site. The honest read is that this is a friction the licence imposes, not a tax: it costs a minute of the customer’s time and it limits the population that can register at all.

Identity verification runs alongside source-of-funds questions at higher spend. The Commission’s financial vulnerability check, in force since 30 August 2024 and applied since 28 February 2025, runs a public-record check on a customer whose net deposits exceed £150 in a rolling thirty days. That is not a credit reference check and not an income check — it looks at county court judgments, bankruptcies and the like. Affordability checks of the kind that attract headlines have been announced in a staged plan, with no published start date.

The 10x wagering cap and the mixed-product ban

The promotion rules in force since 19 January 2026 do two things. First, they cap wagering requirements on bonuses at 10x. Second, they ban mixed-product promotions — any offer that requires gambling on two or more product types, where “product types” includes betting, casino, bingo and lottery. A welcome offer that asks for a sports bet to unlock free spins is no longer allowed at any GB-licensed brand. A welcome offer that hands the customer sports free bets only — and that asks for the qualifying bet and the wagering turnover on sports only — is now the shape of the market.

The cap does not yet say where a free bet without a wagering condition stands; the Commission has not published guidance on that case. Most welcome offers, however, do carry wagering conditions even if they look modest: a 10x cap is still a cap the customer has to clear.

Credit cards, payments and limits

Credit cards are banned for gambling in Great Britain, including credit-card-funded payments through an e-wallet. The rule has been in force since 14 April 2020 and lives in LCCP condition 6.1.2. Debit cards and bank-based payments such as open banking are not covered by the ban, and that is why almost every operator on the comparison insists on a debit card or instant bank transfer for the qualifying deposit.

Deposit limits are the customer’s choice, set inside an account and adjustable only with a delay. LCCP requires operators to offer a gross deposit limit on a fixed time frame; the first changes applied on 31 October 2025, a second phase was postponed to 30 September 2026, and whether that second phase is now live is not established. There is no state-set ceiling on deposits, and no state-set ceiling on losses: each limit is the customer’s own decision, and the trade-off is between gambling affordably and the willingness to accept an overnight review of a withdrawal.

Safer gambling tools and what the licence buys

GAMSTOP and self-exclusion

GAMSTOP is the national multi-operator self-exclusion scheme. Every GB-licensed remote brand takes part, and the scheme has been a mandatory licence condition since 31 March 2020. Exclusions can run for six months, one year, five years, or five years with auto-renewal. The minimum period applies, then a further seven years runs by default unless the customer asks GAMSTOP to lift it. That long tail matters: a customer who self-excludes for six months in 2024 finds themselves still enrolled until 2037 unless they ask to come back.

GAMSTOP covers online sites and apps. The high-street betting shop has its own self-exclusion service run through the shop. The two are not interchangeable: a customer who has self-excluded online can still walk into a betting shop, and a customer who has self-excluded in shops can still open an online bookmaker, which is one reason the scheme asks a customer to cover both routes if they intend to step away from betting altogether.

Limits and the daily loop

Deposit limits, loss limits and wager limits are all available on a GB-licensed account. DAZN Bet lists all three on its account controls. Bet365, Coral and most of the larger operators carry an equivalent panel inside the responsible-gambling section of the account. The settings stick at the level the customer chooses, and a reduction takes effect immediately while an increase takes effect after a delay of a day or a week.

Each operator’s safer-gambling tools are useful, and they are not a substitute for a customer’s own decisions. GamCare runs the National Gambling Helpline and offers free one-to-one counselling; GambleAware funds treatment and education; the NHS operates problem-gambling clinics in several regions; Gamblers Anonymous runs peer-led meetings in most British cities. The licence buys the customer access to these services through the operator’s signposting. The offshore alternative buys none of it.

What an unlicensed site actually costs the customer

A site licensed outside Great Britain can serve a British customer, but it carries no Commission licence. The legal analysis is that a GB licence is compulsory at the point of consumption, and providing gambling facilities in Great Britain without it is the kind of offence the Commission’s enforcement team has spent the last decade being paid to pursue. The customer, by contrast, has no offence to answer for — nothing in the Act names the punter.

The customer’s loss is protection. An unlicensed site has no GAMSTOP integration, no Commission complaints route, no approved alternative-dispute-resolution body, and no statutory hook for British consumer redress if funds are withheld. The 10x bonus cap does not apply. The £150 financial vulnerability check does not run. The credit-card ban does not bind. Identity is still verified in most cases, but only because the operator’s own policies require it, not because the licence does. Saying an offshore site is not “legal to use” is a different claim from “carries no British protection” — the second is the one that matters to a customer deciding where to open their next account.

How a welcome bonus compares across ten GB-licensed brands

The table below lists ten brands from the Commission’s public register against a single grid: the licence number on the register, the licensee name, and the headline shape of each operator’s own stated welcome terms. Operators are listed in the order the Commission register assigns them rather than as a recommendation.

A row that names an offer states it the way the operator’s own terms state it; a row that does not state a figure at headline level reflects what the brand itself publishes as its current shape, not a gap in the check.

Working the offer out behind the bonus

Coral’s welcome offer of £40 in free bets for a £20 stake at 2.0 is the cleanest example to take apart. The qualifying bet costs £20 of real money. If it wins at 2.0 it returns £40, of which £20 is stake returned and £20 is profit — but the customer’s net position is determined by the bet, not by the bonus. The £40 of free bets credited afterwards can be staked across as many wagers as the customer wishes, at minimum odds the terms specify, and they expire seven days after they land. If those free bets are placed at an average decimal price of, say, 3.0 and win, they pay £120 of profit — minus the stake, so £80 of net profit on a £40 outlay. If half of them win, the customer still comes out ahead of the £20 qualifying stake because the free-bet stake is not real money to start with. The trade-off is the seven-day window and the minimum-odds rule on the free bets themselves.

Spreadex’s £60 in free bets for a £10 fixed-odds bet is more generous on the headline multiple but tighter on qualifying conditions. The minimum odds of 1/2 are at the bottom of the scale, but the customer has twenty-eight days to place the bet — long enough for a customer to wait for a fixture they actually want to back. The fixed-odds part is the headline; the package also covers the spread-betting product, which is FCA-regulated rather than Commission-regulated and carries a separate risk profile. Spreadex states that losses on spread bets can exceed the deposit, which is true of every spread-betting provider and is a footnote the customer should not skip.

The free-bet-stake-not-returned rule is the underappreciated part of all of these figures. Coral’s headline number says “£40 in free bets” and the small print says “stake not returned”. A £40 free bet at decimal odds of 3.0 returns £80 of profit — £120 minus the £40 that is not given back. The marketing figure is the position the customer would be in with cash, and the actual position is one third smaller. That is the difference between accepting a bonus and walking away from the welcome offer.

Reading the ten operators one by one

Coral

Coral runs under LC International Limited, the same parent as Ladbrokes, and shares that group’s product portfolio across sports, in-play and gaming. The welcome offer of £40 in free bets for a £20 qualifying bet at minimum odds of 2.0 is one of the longer-running shapes in the GB market and is now well-trodden by customers who treat bookmaker bonuses as a routine cost-saving exercise. Coral qualifies the offer with a debit card or instant bank transfer, and lists Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly as available methods across the account.

Beyond the welcome bonus, Coral runs a free daily Reward Shaker and an Odds Booster on hundreds of markets, alongside free-to-play games that include Football Super Series with a £10,000 jackpot. Bet Builder, in-play markets, Acca Insurance and live streams through Coral TV are all on the platform for customers whose accounts are set up and verified. Customer payouts are processed through the same debit-card-and-bank-transfer rails that funded the qualifying deposit.

Worth it for the customer who plans to place a £20 bet on a Saturday and use the £40 of free bets inside a single week. The qualifying conditions are above the floor; the stake-not-returned rule and the seven-day expiry are the costs the customer pays for the headline.

Spreadex

Spreadex is one of the few GB-licensed operators that runs both a fixed-odds book and a spread-betting book under one account. It is regulated by the Gambling Commission on the fixed-odds side and by the Financial Conduct Authority on the spread-betting side. That dual structure is the brand’s distinguishing feature, and it is the reason the welcome offer accepts bets usable across both products.

The £60 in free bets for a £10 fixed-odds bet at minimum odds of 1/2 is generous on the headline multiple. The qualifying bet must be placed within twenty-eight days, which is generous on the qualifying deadline. Acca Boosts give a cash boost from 5% to 100% on football accumulators of three or more selections, depending on how many legs are stacked. Spread betting losses can exceed deposits on the spread side of the book — the operator states this on its homepage, and the customer’s funding model should reflect it.

Worth it for the fixed-odds customer with a planned bet, and for the spread customer who wants both products in one account. The FCA-regulated side carries a different risk profile from the Commission-regulated side and is not a bonus.

William Hill

William Hill is one of the oldest names in British bookmaking and operates a remote betting book across sports, in-play and gaming under WHG (International) Limited. The Football Acca Boost is the headline ongoing promotion at the brand: accas of two or more legs at 1/5 or bigger carry a boost from 3% on a double up to 200% on twenty or more legs, with a maximum boost of £10,000 per online bet and the promotion running to 30 May 2027.

Beyond the boost, the platform offers Bet Builder, in-play markets, acca insurance and live-streaming coverage across several sports. Customer withdrawals run through the standard debit-card and bank-transfer rails. The brand does not publish a single headline welcome bonus figure of the kind other operators offer — the acca boost structure is its ongoing shape and applies from the first qualifying acca placed by a new customer.

Worth it for the customer who already bets on accas, especially on football. The boost kicks in from the second leg, and a customer who runs small doubles every Saturday can pile up the percentage without major staking commitments.

Fitzdares

Fitzdares is a small, premium-position bookmaker under Fitzdares Limited, taking bets on racing, football and a handful of other sports. The brand accepts Apple Pay, Mastercard and Visa, with Visa withdrawals running same-day and Mastercard withdrawals up to forty-eight hours — a fast-payout setup that matches the brand’s premium positioning.

At the time of review the site does not state a headline welcome-bonus figure in the same shape as Coral or Spreadex, and its in-app promotion has shifted across the bonus, free-bet and acca-offer blocks on selected events. The customer experience is closer to a private bookmaker than a major high-street brand.

Worth it for the customer who values fast payouts and a smaller betting menu over a packaged welcome bonus. The brand is a worse fit for the customer who plans their betting around bonus clearing.

Betboro

Betboro runs under Webmedia Development N.V., an operator registered outside Great Britain, with a Commission licence running under account 44181. Its welcome offer is a 100% matched free bet up to £25 on the first qualifying wager: a debit card deposit of at least £10, a first bet of £5 to £25, with at least three selections each at 3/5 (1.60) or higher. The matched shape is closer to a stake-back arrangement than a free-bet bundle, and it suits a customer willing to put a small acca on as the qualifier.

The matched free bet carries a stake-not-returned rule on the credit itself, and the qualifying bet carries a minimum-acca requirement that pushes the customer’s first wager into a multi-leg format. Bet Builder, in-play markets and casino games complete the platform under the same account.

Worth it for the customer placing a small first acca. The 100% match is honest; the minimum-three-legs requirement is the trade-off.

VBet

VBet is run by SCGO Limited, a Commission-licensed operator, and offers a sportsbook, casino and live-dealer product on one platform. The sports welcome offer is the simplest shape on this comparison: a £10 free bet if a new customer’s first bet of £10 or more loses. The structure is closest to a stake-back arrangement, with the credit landing only on a losing first wager.

If the first bet wins there is no bonus. If it loses, the customer is credited a £10 free bet. That shape suits a customer who plans to place a first bet on something they think is closer to a coin-flip, and it is unsuited to a customer who plans to back a strong favourite as their first punt. Beyond the welcome bonus, VBet offers Bet Builder, in-play markets and an in-app promotion schedule.

Worth it for the customer whose first bet is genuinely uncertain. The “refund” wording makes it sound bigger than the £10 free-bet amount suggests after stake-not-returned.

BetGoodwin

BetGoodwin is the online arm of Goodwin Racing Limited, a Commission-licensed independent bookmaker with roots in British racing. The sports welcome offer is “Bet £10 & Get £15 in Free Bets”, split across three £5 tokens: a £5 sports free bet, a £5 acca free bet and a £5 Sub-Cover free bet. The split format is unusual among welcome offers and suits a customer who bets across single, accumulator and racing markets rather than only one shape.

The £15 headline is modest against the £40 of Coral or the £60 of Spreadex. The split lets the customer try three of the brand’s products, which is a different trade from a single larger free bet. Goodwin Racing Limited’s licence dates back through account 2927 on the Commission’s register, and the platform runs the racing, football and greyhound markets a UK customer expects.

Worth it for the customer placing a small qualifying stake and using all three free-bet shapes across a single weekend. Not worth it for the customer chasing the largest headline figure.

Octobet

Octobet is run by Octopus Game Limited, a Commission-licensed operator, and markets a sportsbook and casino package together on one platform. The headline sportsbook welcome offer is 50% back as a free bet up to £50, plus a £10 casino bonus for new customers. The mixed shape — free bet plus casino credit — is the kind of package the Commission’s 19 January 2026 rules now restrict at GB-licensed brands, and Octobet’s terms should be checked for the current shape of the offer against the rules in force at the moment of registration.

If the offer is still paired, it sits on the boundary of what a GB-licensed operator can offer: a sportsbook offer that requires a sports bet is allowed; a sportsbook offer whose unlock also touches casino is restricted. The customer should read the qualifying bet conditions and check the casino-credit terms separately. Bet Builder, in-play markets and the standard payment rails apply.

Worth it for a customer interested in both products at the same brand — if the bonus structure still applies on the registration day. The mixed-product rule may already have changed the package; the live terms page is the check.

Betmaster

Betmaster is operated by BM Solutions GB Ltd, registered in Malta, with a Commission licence under account 65699. The site states the licence and the corporate structure but does not publish a headline welcome bonus figure at the time of review. The platform carries a sportsbook, casino and live product on one account and accepts debit-card and bank-transfer deposits.

The brand suits a customer who has already checked the licence and wants a Commission-regulated bookmaker without a packaged welcome bonus. The lack of a headline welcome figure is not a sign the brand is unlicensed; it is a sign the brand promotes through a different channel.

Worth it for the customer checking licences rather than welcome figures. A brand whose licence is current and whose terms are clear is not worse than a brand with a £40 bonus, and the customer’s choice on a brand like this should turn on the betting menu and the payout speed rather than a headline number.

DAZN Bet

DAZN Bet runs under DZBT Limited, a Commission-licensed operator, and offers a sportsbook with Cash Out, Bet Builder, daily bet boosts and in-play markets. Cash Out availability is not guaranteed and bets stand if cash out is unavailable — that is the operator’s standing position on the feature, and the customer’s bet is settled at whatever cash-out value is in place at the moment the cash out button is pressed.

The platform’s safer-gambling tools include deposit limits, loss limits and wagering limits, with the customer’s chosen limits applying across the account. The welcome offer is not pulled out as a headline figure at the time of review. Cash Out, Bet Builder and the daily boosts are the platform’s running features.

Worth it for a customer who plans to use cash out and bet-builder products across a season. The brand’s lack of a packaged welcome offer is not a licensing gap.

Working the calculation: what the 10x cap means for a real bonus

The Commission’s new cap is a number, not an abstraction. Take a £10 bonus with a 10x wagering requirement, placed at minimum odds of 2.0 across single bets of £10 each.

Required turnover: £10 × 10 = £100 of qualifying bets. At a stake of £10 per bet and minimum odds of 2.0, that is ten qualifying single bets, assuming the wagering contributes 100% of stake toward turnover.

Number of bets: turnover ÷ stake = £100 ÷ £10 = 10 bets. Each bet needs to win at minimum odds of 2.0 to count toward turnover, and the wider rule is to assume only the bonus amount itself is wagered — not the bonus plus the deposit, because the cap sits on the bonus side.

Now consider the cost. Each qualifying bet carries the margin that the bookmaker bakes into the price. The market margin on a typical Premier League 1X2 sits somewhere between 5% and 8% depending on the bookmaker and the match, and that is the take rate every pound of turnover costs the customer on average. With £100 of turnover, the expected cost lands in a band of roughly £5 to £8, depending on which league and which bookmaker’s market the bets are placed in. The headline value of a £10 free bet that wins is £10 of profit at evens, minus the cost of the wagering turnover on the bonus itself, leaving a real value of somewhere between £2 and £5. A bettor who finds the 5% end of the margin band and meets no other conditions comes out ahead; a bettor at the 8% end in a tight market comes out roughly even.

State the result as the band it actually is: a £10 bonus at the new 10x cap has expected value of about £2 to £5 after margin and stake-not-returned, depending on the market the wagering turnover runs through. The headline figure of £10 is the ceiling before the terms are applied, and the customer’s real outcome is closer to a third of it.

The compounding problem is the same shape, scaling up. A £100 bonus at 10x requires £1,000 of qualifying bets. Ten times the turnover, ten times the margin cost, ten times the time. The cap lifted the worst multipliers but kept the wagering structure in place. A customer who takes a bigger bonus is taking a bigger wagering job, and the expected value of every extra £100 of bonus is still bottlenecked by the margin of the market the clearing runs through.

Other features that matter once the welcome bonus is spent

Bet builders and same-game multis

Bet Builder, sometimes branded Bet Builder+, is a single bet that combines markets from the same event into one wager. bet365’s Bet Builder+ covers pre-match and in-play selections and supports Winnings Boosts on the resulting slips; Kwiff runs both a same-game Bet Builder and a cross-game Bet Builder+; Unibet offers a Bet Builder across its sportsbook; DAZN Bet and most of the major operators run an equivalent.

Same-game multis carry a higher margin than a bet on a single market, because the bookmaker is paying out on correlated outcomes that are easier to overprice. A punter who runs several Bet Builder bets each weekend is paying a margin premium on every one of them. The product is fun; it is also the most expensive way to back a view the customer already holds.

Cash out, in-play and live streaming

Cash Out is a feature that lets the customer settle a bet before the event has finished, at a price the bookmaker sets live. DAZN Bet’s help page states that cash out availability is not guaranteed and that bets stand if cash out is unavailable. That policy is universal across GB-licensed operators and is the single most important rule to read before relying on cash out as a money-management tool.

In-play betting is offered by every major GB bookmaker and is governed by the operator’s own licence conditions rather than a statutory restriction. Live streaming is offered by several brands — Unibet TV runs horse racing and selected other sports; bet365 streams several thousand events a year; SBK streams live horse racing. Each event carries its own terms of access, and a few require a funded account or a recent bet to unlock the stream.

Acca insurance and loyalty schemes

Acca insurance refunds the stake of an accumulator that loses by one selection. BoyleSports’ Acca Insurance requires opt-in, a £5 minimum stake, minimum odds of 1/2 and pays a maximum refund of £20 as a free bet that expires in seven days. The same operator’s Acca Loyalty scheme requires opt-in, a £5 minimum stake, minimum combined odds of 3/1 and five or more settled legs, with a free bet expiring after seven days.

William Hill’s Football Acca Boost sits in the same family but pays out cash rather than free bets. Spreadex’s Acca Boosts give a cash boost from 5% up to 100% on football accas of three or more legs. The bookmaker-by-bookmaker spread is wide, and the customer’s choice depends on whether they prefer a refund structure (small but predictable) or a boost structure (proportional to the legs and paid in cash).

Boosted odds and price boosts

Price boosts are the bread and butter of value on a major bookmaker’s app. Coral offers an Odds Booster on hundreds of markets; Kwiff runs a Supercharge feature that can lift odds from 2/1 to 20/1 instantly; Unibet runs daily Uniboosts; Star Sports runs Daily Specials and Weekend Enhanced Boosts; bet365 runs Super Boosts and daily Bet Boosts. The boost applies to the price the bookmaker quotes; the underlying market margin is the same as for an un-boosted price, and the boost is paid in cash winnings rather than as a free-bet credit.

Boosted odds and price boosts attract an unusual amount of marketing because they look like free money. They are not free money; they are a chosen subset of markets on which the bookmaker has decided to inflate the price to attract custom. Most of the boosted prices are still well inside the bookmaker’s margin on the underlying market, and the customer’s expected edge from taking them is small. They are a fine bonus on top of an existing strategy; they are not a strategy on their own.

Spread betting at Spreadex

Spreadex is the only brand in this comparison that runs a spread-betting book side-by-side with its fixed-odds book. Spread betting carries a different risk profile: a customer’s loss on a single spread position can exceed the deposit that funds it, because the size of the loss is the size of the position, not the size of the stake. Spreadex states on its homepage that losses on spread bets can exceed deposits, and the FCA’s regulation of the spread-betting product reflects that risk.

The brand’s welcome offer allows the credited free bets to be used across fixed-odds and spread-betting products. A customer who plans to use the credit on the fixed-odds side avoids the spread-betting product altogether; a customer who plans to use both has to manage a stake-sizing model that fits the higher variance. The two products are not interchangeable.

Picking a welcome offer by reader type

The fixed-odds-only customer

The customer who plans to back only fixed-odds markets — singles, doubles, occasional accas — has the simplest decision: which operator’s wagering and minimum-odds conditions fit the bets they would have placed anyway. Coral and Unibet both give £40 in free bets for a £20 qualifying bet at 2.0, with seven-day expiry; Spreadex offers a £60 welcome bonus for a £10 fixed-odds bet at 1/2 with a twenty-eight-day window. The customer who already backs big-priced favourites should look at Spreadex’s looser minimum-odds rule; the customer who backs evens shots should look at Coral and Unibet.

The acca customer

The customer who already runs accumulators every weekend is best served by an operator with an acca insurance or acca boost structure. BoyleSports’ Acca Insurance refunds the stake on a one-leg loser; William Hill’s Football Acca Boost pays a cash bonus on a winning acca, scaling with the number of legs; Spreadex’s Acca Boosts give a cash boost on football accas of three or more legs. The right pick depends on whether the customer’s accas typically win or lose — a steady winner wants the boost on the winning side, a steady loser wants the insurance on the failing side.

The spread-betting customer

The customer who already uses a spread-betting book is best served by Spreadex, which lets the credited free bets run across both products. The customer should still read the spread-betting risk warning on the homepage and budget for a position-sizing model that handles the higher variance. A brand like Spreadex is not a one-product operator; the welcome offer is a route into the dual book, and the customer’s account balance has to handle both.

The customer who has self-excluded

A customer who has a GAMSTOP exclusion in place cannot open an account at any GB-licensed brand on this list. The exclusion runs at the level of every Commission-regulated operator, and a fresh welcome bonus does not override the exclusion. The customer who is coming back from a GAMSTOP period can register when the period ends and the seven-year tail has been lifted; until then, no offer is available.

The customer chasing the largest headline figure

The customer who wants the largest headline figure across the ten brands will land on Spreadex, with £60 in free bets for a £10 qualifying bet, or Coral and Unibet with £40 in free bets for £20 qualifying bets. Every figure on this comparison carries the same kind of conditions — minimum odds, time limits, stake-not-returned on the free-bets themselves — and the customer should read them for the brand they pick rather than fixating on the headline. The largest figure is not the largest value.

Frequently asked questions

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

A 10x wagering requirement is the cap on bonuses at GB-licensed operators, in force from 19 January 2026. A £10 bonus at the cap means £100 of qualifying bets before withdrawal. Free bets with no wagering condition are not yet addressed by the Commission’s published guidance, so a no-wagering free bet still needs to be read against the operator’s own terms before the customer assumes it is exempt.

How do you claim a betting welcome offer?

Open an account, complete identity verification, deposit with a debit card or bank transfer, place the qualifying bet at the minimum odds the offer names, and wait for the free bets to credit once the qualifier settles. Free bets land within forty-eight hours on most brands; Coral gives seven days from credit, Unibet gives seven days, QuinnBet gives seven days, and the clock starts at the moment the credit is issued rather than at registration.

Which betting sites have welcome bonuses for new UK customers?

Every brand reviewed on this page holds a Commission licence and publishes a welcome bonus or running promotion in its app or on its site. The shape varies: Coral and Unibet give £40 in free bets for a £20 qualifying bet at minimum odds of 2.0; Spreadex gives £60 in free bets for a £10 qualifying bet at minimum odds of 1/2; Betboro gives a 100% matched free bet up to £25 on an acca qualifier; BetGoodwin splits £15 across three £5 free bet tokens; VBet refunds the qualifying stake as a £10 free bet if the first bet loses.

Which betting welcome bonus gives the most value?

Spreadex carries the largest headline figure at £60 in free bets for a £10 qualifying bet, but the actual value depends on minimum odds, expiry and the stake-not-returned rule on the credited free bets. A £60 headline at 1/2 minimum odds with a twenty-eight-day qualifying window and a stake-not-returned free-bet stake is closer in value to Coral’s £40 at 2.0 with a seven-day window than the raw number suggests. The right measure is the value after the terms, not the headline before.

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

Minimum odds is the lowest price the qualifying bet may be placed at to count toward the bonus. Coral and Unibet ask for 2.0; Spreadex asks for 1/2 (1.50); Betboro asks for at least three selections each at 3/5 (1.60) or higher. The wagering requirement is the multiplier that decides how many times the bonus must be turned over in qualifying bets before withdrawal. The 10x cap sits on the bonus side, so a £10 bonus with a 10x wagering requirement means £100 of qualifying bets; on a £100 bonus it means £1,000 of qualifying bets.

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

The bookmaker pays out the winnings of a free bet at the price chosen, but treats the stake as the cost of the offer rather than as part of the customer’s balance. A £10 free bet at 3.0 returns £30 of profit, not the £40 a real-money bet at 3.0 would return, because the £10 stake that the customer would have risked on a real bet is being credited to them as the bonus. The arrangement is the way a free bet is priced into the offer: a brand that returns the stake looks more generous but charges for it through smaller bonuses or tighter conditions elsewhere.
