The first offer a bookmaker shows a new customer in Great Britain is rarely the headline number it looks like. A “£40 in free bets when you bet £20” headline becomes something sharper once minimum odds, expiry, stake-return rules and the Gambling Commission’s 10x wagering cap sit beside it. The point of this guide is to make that translation: what the offer is, what it costs to clear, and which of the ten licensed brands that pay attention to it suit a particular kind of punter.

The bookmaker promo code is itself a smaller thing than the marketing suggests. Almost no UK-licensed brand requires a code at sign-up any longer — the offer is triggered by a qualifying deposit and bet, and the “code” usually lives as an affiliate link that turns the same headline on for any new account. Codes have not disappeared because they are useful; they have disappeared because the regulator’s promotion rules, in force since 19 January 2026, look at the offer the customer receives rather than the route they used to get it. The page below works through those rules first, then the welcome offers, then the ten brands themselves.

Data current as of 27 October 2026; offer terms, licence numbers and safer-gambling commitments cross-checked against the Gambling Commission’s public register and each operator’s own UK site.

The landscape of UK betting offers

A promotional offer at a GB-licensed bookmaker falls into one of a handful of shapes, and the reader who can place an offer in its shape before reading the headline is the reader who notices the condition that does the work.

The most common shape is the matched free bet: place a qualifying bet at the bookmaker’s minimum odds and minimum stake, and the bookmaker credits free bet tokens of equal or greater face value. Coral and Unibet’s £40 in free bets for a £20 qualifying bet, Betway’s four £10 tokens for a £10 first bet and Sky Bet’s three £10 tokens after a 5p first bet are all this shape, and at first glance they look generous because the headline is more than the qualifying stake.

What the headline often omits is the token’s stake-return rule: the stake is never returned with winnings. A £10 free bet at odds of 3.0 returns £20 in profit, whereas a £10 cash bet returns £30 (the £20 profit plus the £10 stake). This difference explains why marketing headlines like “free £30” refer to the return of a cash bet, while the maths of a free bet delivers £20.

A smaller shape is the refunded-as-free-bet insurance: a stake returned as a free bet if the qualifying bet loses, rather than as cash. Hollywoodbets’ “stake back as a free bet of up to £30” on a first losing accumulator is the worked example; BetUK’s set of four free bets after a first losing sports bet is the same shape with different mechanics. The word “refund” hides the same stake-not-returned rule.

A separate shape altogether is the price boost: an enhanced price on a named selection, credited as cash winnings rather than as a free bet, on condition the bet wins at the boosted price. William Hill’s Football Acca Boost, Coral’s Odds Booster and the daily price boosts at bet365 and BetVictor all sit here. The stake is returned in cash because the bet was paid for in cash; only the price was inflated.

Last is the acca insurance and acca loyalty shapes: a refund (as a free bet) on a losing accumulator with one let-down leg, or an extra cash bonus on a winning accumulator with enough legs. BoyleSports’ Acca Insurance and Acca Loyalty, Spreadex’s Acca Boosts and Copybet’s Acca Booster all sit in this cluster, and they are the offers that look smallest in the headline and matter most for the punter who bets accumulators week to week.

What “free bet” really means

Three sentences carry the rest of the page, and they are worth setting out before any brand is named.

A free bet functions as a token rather than cash, and the stake is withheld if the bet wins. Betting £10 at 3.0 odds yields £20 in profit; the initial £10 value of the token is not paid out.

The minimum odds on a free bet decide how much of the betting menu it can actually be used on. QuinnBet’s 7-day free bets at minimum odds of 1/2 (1.50) cover most of the book; a brand whose free bets are restricted to odds of 5.0 or greater funnels the token towards a narrower set of selections.

A free bet with a wagering requirement turns into the Commission’s 10x cap. Whether that cap applies to a free bet whose headline carries “no wagering” is not established; it applies to any bonus whose headline carries a rollover. A £10 bonus with a 50x requirement would have meant £500 of qualifying bets; under the cap it stops at £100.

The legal frame around every offer

What the Gambling Commission allows and does not allow

The Gambling Commission regulates commercial gambling in Great Britain under the Gambling Act 2005. Every online bookmaker whose services are used in Great Britain needs a Commission licence, and the licence is held against a specific legal entity rather than a brand: Platinum Gaming Limited holds Unibet’s, BV Gaming Limited holds BetVictor’s, SBG Sports Limited holds Sky Bet’s. Several brands can run under one licence, and a single brand can sit on more than one licence category. The Commission’s public register is the whole test of who is licensed; the licence number on the operator’s own site should reconcile against it.

Financial spread betting is a different kettle of fish. It is regulated by the Financial Conduct Authority, not the Commission, and a brand that does both (Spreadex, for one) holds an FCA registration for the spread side and a Commission licence for the fixed-odds side. The distinction matters because FCA-regulated spread bets can lose more than the deposit; Commission-regulated fixed-odds bets cannot.

Northern Ireland is outside the Gambling Act 2005 and runs its own older regime. A “GB-licensed” bookmaker is licensed for England, Scotland and Wales, not for Northern Ireland; the language on the operator’s site will sometimes say “UK” and mean “GB” by it.

Promotion rules in force since 19 January 2026

Two rules rewritten the UK bonus market at the start of 2026.

The first is the wagering cap. Any bonus offered to a GB customer must not carry a wagering requirement above 10x. A £10 bonus at 50x would have meant £500 of qualifying bets; under the cap no bonus can require more than £100 in turnover for every £10 of bonus value. The cap is silent on the maximum bonus amount itself, on the maximum value of a free bet, and on whether free bets without a stated wagering condition fall inside the cap at all. Those three questions are unsettled, and the page cannot answer them from the Commission’s published rules.

The second rule is the mixed-product ban. A promotion that ties betting to another product — a sports bet that unlocks free spins, a casino offer that needs a sports wager to qualify — is no longer permitted at all. Every bonus reviewed below is sports-only because that is what survives the rule.

What the rules do not do is set a minimum odds requirement, a stake cap, an expiry window, or a “reasonable” headline value. Those are the operator’s choices and live in the small print of each welcome offer.

What the rules do for the punter

The cap does not change the headline value of an offer; it changes the turnover it asks for. A £40 free-bet bundle with a 5x wagering requirement would have meant £200 of qualifying bets before any withdrawal; under the cap the same bundle can ask for at most £400 of qualifying bets. Below the cap there is no rule; an offer that asks for nothing at all (most matched free bets) sits outside the cap because there is no rollover to cap.

The mixed-product ban means a sports punter no longer sees offers whose real value depends on opening a casino account. A sports-only welcome offer can be read on its own terms.

Responsible gambling in the offer

A welcome offer sits inside a wider set of safer-gambling controls, and the punter who reads the offer without the controls is reading only half of it.

Identity, age and the first deposit

Every GB-licensed operator verifies name, address and date of birth before the first deposit can be made or the first bet (including a free bet) can be placed. The verification has been a licence condition since 7 May 2019. Anonymous play is no longer available at a licensed site, and a brand that promises otherwise is either offshore or breaking its licence.

GAMSTOP

GAMSTOP is the national multi-operator self-exclusion scheme. It is a mandatory licence condition for online operators in Great Britain; every GB-licensed bookmaker takes part. The minimum exclusion is six months; periods then run to one year, five years, or five years with auto-renewal. After the chosen 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 only. Betting shops use a separate multi-operator scheme. An exclusion at GAMSTOP does not stop a customer opening a new account at an offshore brand outside the Commission’s reach; it stops them at every GB-licensed operator on the register.

Financial vulnerability and risk checks

The Commission’s customer-commissionary controls have been tightened in stages since 2024.

The financial vulnerability check is in force since 30 August 2024. It applies once a customer’s deposits minus withdrawals cross £150 in a rolling 30-day window (in force since 28 February 2025). It is a public-record check — bankruptcy registers, county court judgments — not an income check and not a credit reference check. Its purpose is to flag a customer whose financial position is already in public distress, not to assess disposable income.

The financial risk assessment (the “affordability check” of the press) has been announced in a staged plan, with no start date. The Commission’s own publication of 7 July 2026 sets out the stages; none is in force at the time of writing. The page does not treat it as live.

Deposit limits and stake limits

There is no state-set deposit or loss ceiling for sports betting in Great Britain. Limits are the customer’s choice and the operator’s product. The Commission’s Remote Technical Standards require operators to offer deposit limits on a fixed time frame; the first changes have applied since 31 October 2025 and a second phase was postponed to 30 September 2026. Whether the second phase is live at the date of this page is not established, and the operator’s own deposit-limit page is the place to check.

A stake limit at the brand level is a different thing again: the maximum the bookmaker will accept on a particular market, which can be cut without notice and which is not a regulatory number. A punter whose usual stake exceeds a brand’s max is a punter who needs to ask the brand, not the regulator.

Where to get help

GamCare runs the National Gambling Helpline. GambleAware funds treatment and research. The NHS runs gambling clinics in several regions. Gamblers Anonymous runs peer-support meetings. The punter who feels the offer is doing the betting, rather than the other way round, has a list of places to ring before any further deposit.

What the welcome offers actually ask for

This is the part of the page that translates the headlines. The five offers below are taken from the ten brands reviewed later; each carries a minimum qualifying stake, a minimum odds line, an issue window for the free bet, an expiry window, and any stake-return or wagering condition research was able to confirm.

A handful of patterns sit across the table. Eight of the ten offers expire within 7 days of issue; Spreadex is the outlier at 28 days for the qualifying window, with the free bets following the standard 7-day rule; Hollywoodbets’ 7 days is the time the qualifying acca must be settled within rather than the free bet’s life. Nine of the ten are matched free bets with the stake not returned; 10bet is a cash bonus whose turnover carries the Commission’s 10x cap; Hollywoodbets is a stake-refund whose refund is itself a free bet.

The single most important pattern is the minimum odds. Eight of the ten offers ask for a minimum of 1/1 (2.0) on the qualifying bet; Spreadex is at 1/2 (1.5); SBK is at 3.0; Hollywoodbets is at 4/1 (5.0) on the acca. A punter who wants to qualify the offer with a hot favourite at odds of 1.2 will be refused at most brands; the Spreadex and SBK thresholds are the floor and ceiling of the range.

The 5p minimum at Sky Bet is the smallest qualifying stake in the table and reflects how thin the headline is: £30 of free bets for a 5p bet. It is also the offer most likely to attract the punter who has no interest in the qualifying bet at all; the brand is paying the £30 partly as an affiliate fee and partly as a customer-acquisition cost, and the £30 is real money provided the 7-day expiry is respected.

How a welcome offer clears under the new rules

The arithmetic below is the arithmetic the Commission’s 10x cap was written to bound. Coral’s £40 free-bet bundle is used as the example, because Coral’s terms are the most fully published and the shape of the answer is the same for every other offer of this type.

The free bets themselves carry no stated wagering requirement: they are tokens, not bonuses, and the Commission has not established whether the 10x cap reaches them. What the cap does reach is any cash bonus a brand offers on top, and 10bet’s 100% up to £50 cash bonus is the cleanest worked example.

The 10x cap applied to 10bet’s bonus

10bet advertises a 100% up to £50 betting bonus for UK sign-ups. Take the headline at £50. A 10x wagering requirement means at most £500 of qualifying bets before the bonus becomes withdrawable; under the cap, no bonus can require more than that.

Assume the punter places single bets of £10 each at minimum odds that satisfy the bonus terms (the brand does not state the minimum in the app listing; check 10bet’s own terms before claiming). At £10 per bet, £500 of turnover is fifty bets. The expected cost of clearing the bonus depends on the margin of the markets the punter bets on. At a 5% margin — typical of a sharp Premier League 1X2 — the punter expects to lose £25 of the £500 in margin, before any account-level considerations. The bonus is worth £50; the expected cost is roughly £25; the net expected value is around £25.

Where the punter bets on markets with wider margins — a same-game multi at 8% margin, an in-play exotic at 7% — the expected cost climbs, and the EV narrows. The cap protects the punter from the worst of it: a 50x rollover on a £50 bonus would have meant £2,500 of turnover and an expected cost of £125 to £200 depending on margin, against the same £50 of bonus value. Under the cap the worst case is half that.

The numbers above are estimates. They assume every bet is at the minimum stake and that the punter is indifferent between markets; a punter who picks accas a small number of legs at higher margins clears the bonus more expensively than a punter who spreads the turnover across singles. The point of the cap is to put a ceiling on the second punter’s bill, and the ceiling is what the cap does.

What the cap does not do

The cap does not set a maximum bonus amount. A brand could offer a £500 bonus at 10x and ask for £5,000 of turnover, which is within the rule. The cap does not require the operator to publish the wagering requirement before opt-in; the small print is still where the multiplier lives. The cap does not touch the minimum odds on qualifying bets, the expiry window, or any cap on free-bet winnings. The reader who treats the cap as a complete consumer protection is reading more into it than the rule carries.

The ten licensed brands, side by side

The table below names the brand, its licence account number, the legal entity that holds the licence (which is not always the brand name), and what the brand’s own terms state on the offer subject this page is about. The licence numbers reconcile against the Gambling Commission’s public register.

A few patterns sit in the table. Six of the ten brands are matched free-bet offers with the headline “X free bets for a Y qualifying bet”, with X running from £20 to £60 and Y from 5p to £20. Two are refund-shaped (Hollywoodbets, BetUK). One is a cash bonus (10bet). One is a feature-led welcome package rather than a headline free bet (Copybet, where the Acca Booster is the prominent recurring promotion). The licence holders are not the brand names in four of ten cases — BetUK sits under LeoVegas Gaming PLC, Hollywoodbets under its international UK subsidiary, Sky Bet under SBG Sports, 10bet under Blue Star Planet — and the reader who wants to check the licence should look up the legal entity, not the trading name.

The headlines cluster around £30 to £40 of free bets, with Spreadex’s £60 the high and BoyleSports’ £20 the low. The qualifying stake runs from 5p (Sky Bet) to £20 (Coral, Unibet), and the qualifying odds from 1/2 (Spreadex) to 4/1 (Hollywoodbets on the acca). The expiry is overwhelmingly 7 days, with Spreadex’s 28-day qualifying window the outlier.

The ten brands in detail

Each of the brands below carries the Commission’s licence, the headline welcome offer as the brand’s own UK site states it, and the terms that shape what the offer is actually worth. The verdict at the end of each block is the page’s own read of the brand against its rivals, not a recommendation.

Unibet: the live-betting shopfront

Unibet has operated since 1999 and its UK site is run by Platinum Gaming Limited, Gibraltar, under Gambling Commission account 45322. The sports welcome offer mirrors Coral’s: £40 in free bets for a £20 qualifying bet at minimum odds of 2.0 (1/1), with the free bets expiring within 7 days of issue and the qualifying deposit limited to a debit card or instant bank transfer.

The feature set is what sets Unibet apart: Bet Builder, daily Uniboosts, live streaming through Unibet TV, in-play betting, Best Odds Guaranteed on horse racing and Cash Out on thousands of markets. A punter who bets in-play, watches the stream in the same tab and lays the bet off with Cash Out is using Unibet the way its product page describes.

The 7-day expiry on the free bets is the same constraint every other brand carries; the £20 minimum qualifying bet is heavier than Sky Bet’s 5p but lighter than Coral’s; the debit-card-only funding rule narrows the welcome offer to one payment method and excludes anyone whose main card is a credit card (which is illegal for gambling in GB anyway) or an e-wallet not on the eligible list.

The verdict: Unibet suits the punter who wants the live-betting, streaming and Cash Out package around the welcome offer, and who is comfortable qualifying the offer with a debit card or bank transfer. The £40 headline is the same as Coral’s and the terms are materially the same; the difference is the product around the offer.

Paddy Power: the feature catalogue

Paddy Power runs under PPB Counterparty Services Limited on Gambling Commission account 39439. The brand’s app listing leans on features rather than a single welcome headline: Bet Builder+, Popular Bet Builders, Super Sub (a bet rolls over to the replacement if a selected player is substituted), expanded Win More markets and player and ACCA stats.

Super Sub is the unusual one. In a normal Bet Builder, a substituted player voids the leg; under Super Sub the bet rolls over to the replacement player and settles on the substitute’s statistics. For a punter who builds Same-Game Multi bets around a star player, the rule is the difference between a settled bet and a voided one.

The features catalogue is the welcome offer for Paddy Power in the sense that the brand does not lean on a single headline figure the way Coral or Unibet does. The punter who chooses Paddy Power for the welcome offer is choosing a feature package whose headline value is harder to put a number on.

The verdict: Paddy Power suits the Same-Game Multi punter who wants Super Sub and the player-stat integration around the bet, and who treats the welcome offer as a small bonus on top of the product rather than the reason to sign up.

Copybet: the acca shop

Copybet runs under Copybet UK Limited on Gambling Commission account 53774. The brand’s headline promotions are the Acca Booster, paying up to a 100% cash bonus on accumulators of at least 3 selections, and the Daily Profit Boost, paying up to a 15% cash boost on named markets.

The Acca Booster pays in cash, not in free bets, which is the structural difference from the matched-free-bet cluster. A winning acca at the maximum 100% bonus pays the boosted cash winnings straight into the withdrawable balance; there is no token to spend. The Daily Profit Boost is a price boost on a named selection, also paid in cash.

The cap on the Acca Booster (up to 100%) and the cap on the Profit Boost (up to 15%) are the ceilings, not the floor; the actual boost on a 3-fold acca is below 100% and depends on the legs. The punter who reads “up to 100%” as “100%” is reading the marketing rather than the small print.

The verdict: Copybet suits the acca punter who wants the cash bonus rather than the free-bet token, and who is comfortable working from the boost tiers rather than a single headline. For a punter who bets singles, the brand’s feature set is thin.

London Bet: the small-stakes newcomer

London Bet is published by Thistle Bet Limited and licensed by the Gambling Commission under account 66162. The app has a 17+ App Store age rating and the listing states the brand is licensed and regulated in the UK.

The brand is licensed, serves the London market specifically with a brand identity built around it, and its welcome offer is not as fully published as the bigger brands’. The reader who is considering London Bet is choosing a smaller operator whose product catalogue is narrower than the majors’.

The verdict: London Bet suits the punter who values a London-facing brand and a UK-licensed product, and who is comfortable with a smaller operator’s narrower market catalogue. For a punter who wants the feature catalogue of a Paddy Power or a bet365, the brand is not the right shop.

Betway: the £40 standard

Betway runs under Betway Limited on Gambling Commission account 39372. The sports welcome offer is the standard matched free bet: £40 in free bet tokens (4 × £10) credited on settlement of a first bet of at least £10 at minimum odds of 2.0, with a 7-day expiry and debit-card deposits only.

The structure is the £40 headline for a £10 qualifying bet at 1/1. The 4 × £10 split means the punter can spread the free-bet value across four selections rather than stake it all on one; for a punter who likes to place a £10 free bet at longer odds than the brand’s minimum, the split is the difference between one shot and four.

The debit-card-only restriction is the same constraint as Unibet’s. The 7-day expiry is the standard window. The minimum odds of 2.0 are the standard minimum.

The verdict: Betway suits the punter who wants the £40 headline against a £10 qualifying stake and the freedom to use four £10 tokens rather than one. The brand’s wider product is solid but unspectacular, and the welcome offer is the main reason to choose it over a rival.

10bet: the cash-bonus outlier

10bet runs under Blue Star Planet Limited on Gambling Commission account 43173. The brand advertises a 100% up to £50 betting bonus for UK sign-ups plus daily free bets and free spins (subject to the 10x cap on the bonus and to the mixed-product ban on the free spins).

The offer shape is different from the matched free-bet cluster: a cash bonus with a wagering requirement, not a free-bet token. Under the Commission’s 10x cap, the maximum turnover is £500 on a £50 bonus, and the punter who clears it with single bets at a sharp market margin gives back roughly £25 of expected value to the bookmaker.

The “daily free bets and free spins” line is the place the mixed-product ban bites: any promotion that ties betting to another product is no longer permitted at a GB-licensed operator, and a sports welcome offer that hands out casino free spins along the way cannot do so as part of the welcome package. The free spins may be a separate promotion available to existing customers; they cannot be the bait for the sports bet.

The verdict: 10bet suits the punter who wants a cash bonus rather than a free-bet token and is willing to clear the 10x cap to do so. The headline figure is lower than the matched-free-bet rivals but the structure is closer to the classic “deposit bonus” the Commission’s cap was written to bound.

BetVictor: the price-boost house

BetVictor runs under BV Gaming Limited on Gambling Commission account 39576. The brand’s app listing leans on regular price boosts, acca offers and free bets on selected events; the welcome offer lives in the app and is governed by the customer terms and conditions rather than by a single headline on the homepage.

Price boosts are the brand’s centre of gravity: enhanced odds on a named selection, credited as cash winnings on a winning bet. A punter who bets singles on Premier League fixtures will find more boosted prices at BetVictor than at most rivals; a punter who bets accas will find the acca offers alongside them.

The welcome offer varies — a £30 free-bet bundle, a risk-free first bet, an acca offer — and the customer terms apply. The punter who claims the BetVictor welcome offer reads the customer terms, not the homepage.

The verdict: BetVictor suits the punter who values price boosts and acca offers over a single welcome headline, and who is comfortable reading the customer terms before opting in. For a punter who wants the cleanest £40-for-£20 headline, Coral or Unibet is the more legible offer.

Hollywoodbets: the refund-shaped newcomer

Hollywoodbets runs under Hollywoodbets International UK Limited on Gambling Commission account 53028. The sports welcome offer is a stake refund on the first losing accumulator, paid as a free bet of up to £30: a £10+ stake, 3+ legs, odds of 4/1 or greater, settled within 7 days, one free bet per customer.

The shape is “money back as a free bet if your first acca loses”, and the conditional structure is what makes it interesting. The punter is being asked to risk an accumulator at 4/1 minimum — a multi-leg bet with each leg at odds shorter than 4/1 individually but combined longer — for the chance of a free bet if the bet loses. The free bet is itself subject to the stake-not-returned rule.

The “up to £30” cap means the refund scales with the stake up to £30; a punter who stakes £30 gets £30 back, a punter who stakes £10 gets £10 back. The 4/1 minimum and the 3-leg minimum narrow the qualifying market to accas of three or more selections at combined odds of 4/1 or greater.

The verdict: Hollywoodbets suits the acca punter who wants a safety net on the opening bet and is comfortable betting an acca at 4/1+ to qualify. The refund-as-free-bet shape means the punter is still playing through a free bet on the second bet, and the headline value is capped.

BetUK: the four-token bundle

BetUK runs under LeoVegas Gaming PLC on Gambling Commission account 39198. The brand’s sports welcome offer hands out four £10 free bets (two football accumulators of 4+ selections and two multiples of 2+) after a first £10 sports bet within 7 days of registering, with opt-in required.

The four tokens are restricted by bet type: two must be used on football accas of 4+ legs, two on multiples of 2+ legs across any sport. A punter who does not bet football accas gets two of the four tokens they cannot use, and the headline value of £40 is conditional on the punter wanting to place those bet types.

The 7-day window from registration means the punter has a week to place the qualifying bet and then the standard 7-day window on the tokens themselves. The £10 minimum deposit and minimum stake are the standard thresholds.

The verdict: BetUK suits the punter who bets football accas and other multiples and is comfortable using all four tokens within the window. For a punter whose betting menu is singles only, two of the four tokens are stranded.

Sky Bet: the 5p qualifier

Sky Bet runs under SBG Sports Limited on Gambling Commission account 67370. The welcome offer is the smallest qualifier in the comparison: a deposit of at least £5, a first single or each-way bet of at least 5p at odds of 1/1 or greater, and £30 in free bets credited as three £10 tokens.

The qualifier is the cheapest entry in the table — 5p on a single bet at evens or longer — and the £30 headline is real money. For a punter who does not want to risk a meaningful stake on the qualifying bet, Sky Bet is the smallest barrier in the comparison.

The three-token split (£30 as three £10 tokens) gives the punter three shots at using the free-bet value across three selections. The 7-day expiry is the standard window. The minimum odds of 1/1 are the standard minimum.

The verdict: Sky Bet suits the punter who wants the cheapest possible qualifying bet and the three-token split rather than a single £30 token. The headline value is lower than Coral’s £40 or Unibet’s £40, and the qualifier is correspondingly cheaper.

Beyond the welcome offer

A welcome offer is a small part of a brand’s relationship with the punter. The recurring promotions, the safer-gambling controls and the payment terms shape the longer run.

Recurring promotions

Coral runs a free daily Reward Shaker, an Odds Booster on hundreds of markets, and free-to-play games such as Football Super Series with a £10,000 jackpot. Paddy Power leans on Bet Builder+ and Super Sub. Unibet runs daily Uniboosts, in-play streams and Cash Out. William Hill’s Football Acca Boost runs from 3% on a double up to 200% on 20 or more legs, with a £10,000 maximum boost per online bet, until 30 May 2027. Bet365 layers Bet Builder+, Super Boosts, Winnings Boosts on Bet Builders and selected singles, and daily Bet Boosts. BoyleSports runs Acca Insurance (£5+ stake, 1/2 minimum odds, £20 maximum refund as a 7-day free bet, same-day settlement) and Acca Loyalty (£5+ stake, 3/1 combined minimum odds, 5+ settled legs, 7-day free bet). Spreadex runs Acca Boosts from 5% to 100% on football accas of 3+ selections. Copybet’s Acca Booster is up to 100% cash; its Daily Profit Boost is up to 15%. Kwiff’s Supercharge can instantly boost the odds on a bet (a 2/1 bet becomes a 20/1 bet) on singles or multis on any sport. Smarkets’ SBK bookmaker carries Cash Out, Bet Builder and live horse racing streams alongside the welcome offer.

The cluster matters because the welcome offer is paid once and the recurring offer is paid every week. A punter who bets accas on Premier League fixtures will see more value from BoyleSports’ Acca Insurance or Copybet’s Acca Booster over a season than from any of the £30-to-£40 welcome bundles.

Payments and the credit-card ban

Credit cards have been banned for gambling in Great Britain since 14 April 2020 (LCCP condition 6.1.2). The ban covers credit-card-funded payments through an e-wallet; a punter whose only card is a credit card cannot fund a gambling account at a GB-licensed operator. Debit cards and bank-based payments are not covered by the ban.

Coral lists Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly among its payment options, and the welcome offer must be qualified with a debit card or instant bank transfer. The reader who funds their betting with a credit card is the reader the ban turns away from the licensed market.

Cryptocurrency is not established at GB-licensed operators either way: there is no statutory rule for or against it, and a brand that accepts it is making a product decision rather than a regulatory one. A punter who wants to bet with crypto is choosing a brand whose terms support it; the Commission’s safer-gambling controls (deposit limits, GAMSTOP, vulnerability checks) still apply.

Tax on winnings

The punter 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 remote betting rate of 25% applies within it, while remote bets on UK horse racing, self-service betting terminal bets, pool betting and in-person betting stay at 15%). Spread betting has its own rates (3% financial, 10% other). The Commission’s statutory levy is a separate charge on operators, not a tax on customers.

A professional gambler (someone whose betting is a trade, not a hobby) should ask HMRC or an adviser; the general information above is not tax advice.

The shape of the comparison

The ten brands divide into three loose groups, and the reader who places a brand in its group before reading the headline is reading the headline more sharply.

The matched-free-bet cluster — Coral, Unibet, Sky Bet, Betway, BoyleSports, Spreadex, BetUK — runs the standard shape: a qualifying bet at a stated minimum stake and minimum odds, a free-bet bundle issued within days, a 7-day expiry, the stake not returned. The headline runs from £20 (BoyleSports) to £60 (Spreadex); the qualifying stake runs from 5p (Sky Bet) to £20 (Coral, Unibet). The punter’s decision in this cluster is the size of the bundle against the size of the qualifying bet, and whether the 7-day expiry fits the betting menu.

The refund-shaped cluster — Hollywoodbets, BetUK — runs the “money back as a free bet if the first bet loses” shape. The punter is being asked to risk a first bet for the chance of a free bet if it loses; the free bet is itself subject to the stake-not-returned rule. Hollywoodbets’ minimum of 4/1 on the qualifying acca narrows the qualifying market to multi-leg bets at combined odds of 4/1 or greater.

The cash-bonus cluster — 10bet, and the cash components of Copybet’s Acca Booster and William Hill’s Acca Boost — runs a different shape: a cash bonus or a cash boost paid on winnings, with turnover attached to the cash bonus and not to the boost. Under the Commission’s 10x cap, a £50 cash bonus requires at most £500 of qualifying turnover; the expected cost depends on the margin of the markets the punter bets on.

The reader who reads every offer on the page as “free money” is reading the marketing; the reader who reads each offer on its own shape is reading the small print. The 10x cap, the stake-not-returned rule and the mixed-product ban are the three rules that make the second kind of reading worth the trouble.

What this page is not for

This page is not a tip sheet. Nobody can tell a reader who will win a football match, a horse race or a tennis match, and a “sure bet” or a “system” that promises one is a system that costs the reader real money.

This page is not a ranking. The ten brands are listed because they hold a Gambling Commission remote licence and are reviewed against that licence; a place in the comparison is not an endorsement and a brand outside the ten is not unlicensed.

This page is not a payment-method guide. The credit-card ban is noted; e-wallets and bank-based payments are described qualitatively; cryptocurrency is not established at GB-licensed operators.

This page is not a tax guide. The note on General Betting Duty is general information; a professional gambler asks HMRC or an adviser.

This page is not a substitute for the operator’s own terms. The headline offer, the minimum odds, the qualifying stake, the expiry window and any payment-method restriction live in the operator’s own small print. The reader who opts in reads the small print, not this page.

Final word

The welcome offer at a GB-licensed bookmaker in 2026 sits inside a tighter set of rules than it did two years ago. The 10x cap bounds the worst of the small print; the mixed-product ban removes the bait-and-switch between sports and casino; the verification before the first deposit removes anonymous play; GAMSTOP gives the punter who needs to stop a tool that covers every licensed brand at once.

The ten brands reviewed here all hold a Gambling Commission licence, all participate in GAMSTOP, and all offer a welcome promotion that fits inside the rules. The punter’s choice between them is the choice between matched free bets, refund-shaped offers and cash bonuses at different headline values, qualifying stakes and qualifying odds. The marketing word for any of them is “free”; the maths is the table above and the small print.

Read the small print. Read it before opting in, before placing the qualifying bet, before the 7-day expiry. The reader who does reads the offer the way the Commission’s rules assume it will be read.

Frequently asked questions

What is the cheapest qualifying bet for a UK welcome offer?

Sky Bet’s 5p minimum on the first single or each-way bet at odds of 1/1 or greater is the smallest qualifier in the comparison, and Spreadex’s 1/2 (1.5) minimum odds are the loosest floor. Most other brands ask for £10 at minimum odds of 2.0.

Are promo codes still needed at UK bookmakers?

Almost no GB-licensed brand requires a code at sign-up. The offer is triggered by a qualifying deposit and bet on the brand’s own page. Affiliate links still carry the offer; the affiliate code is the URL rather than a text token.

What happens to a free bet if the selection is void?

A void selection typically voids the free bet, and the stake is not returned. A punter whose free bet contains a voided leg should expect the bet to be voided rather than the odds adjusted; brand-specific rules vary, and the operator’s small print is the place to check.

Can a free bet be split across multiple selections?

It depends on the brand. Betway’s £40 welcome offer is split into four £10 tokens by default; Sky Bet’s £30 is three £10 tokens; Coral’s and Unibet’s £40 is a single bundle that the punter can place in one bet. The free-bet terms on the operator’s site state whether the bundle can be split.

Does the Commission’s 10x cap apply to free bets with no wagering condition?

The Commission’s published rules cap the wagering requirement on bonuses at 10x; whether the cap reaches free bets whose headline carries “no wagering” is not established. The cap is the ceiling on the rollover a bonus can carry; a free bet with no stated rollover is not the same as a bonus.

Are winnings from a free bet paid in cash?

Yes — winning free bets are paid in cash, though the token’s value itself is not returned. Using a £10 token at 3.0 odds results in £20 of withdrawable winnings, assuming no additional wagering requirements apply.

How long does a typical UK welcome offer last?

Most free-bet bundles expire 7 days after issue; Spreadex’s qualifying window is 28 days but the free bets follow the standard 7 days; Hollywoodbets’ refund runs against a first acca settled within 7 days. A punter who does not use the free bet within the window forfeits it.

Where can a punter self-exclude across every UK brand?

GAMSTOP, at the gamstop.co.uk domain, is the national multi-operator self-exclusion scheme. Every GB-licensed online bookmaker takes part. Minimum exclusion is six months; periods run to one year, five years, or five years with auto-renewal.

What is the difference between a matched free bet and a stake-refund bet?

A matched free bet credits free-bet tokens on settlement of the qualifying bet, win or lose. A stake-refund bet refunds the stake as a free bet if the qualifying bet loses. The stake is not returned on either; the difference is whether the free bet is issued on a win or on a loss.

Is spread betting taxed differently from fixed-odds betting?

Yes. Financial spread betting is regulated by the Financial Conduct Authority, not the Gambling Commission; spread betting duty is 3% on financial bets and 10% on other spread bets. General Betting Duty on fixed-odds remote betting is 15% until 1 April 2027, when a 25% remote rate applies within it; UK horse racing, self-service betting terminals, pool betting and in-person betting stay at 15%.

How are promo codes used at betting sites?

Almost no GB-licensed brand requires a promo code at sign-up any longer. The offer is triggered by a qualifying deposit and bet on the brand’s own sign-up page, and the “code” usually lives as an affiliate link that turns the same headline on for any new account. A punter who has been sent a code by an affiliate enters it in the sign-up form (or follows the affiliate link); a punter signing up directly does not enter one and receives the same headline offer.

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

The Gambling Commission’s promotion rules in force since 19 January 2026 cap the wagering requirement on a bonus at 10x. A £10 bonus with a 50x requirement would have meant £500 of qualifying bets; under the cap, no bonus can require more than £100 of turnover for every £10 of bonus value. The cap applies to bonuses; whether it applies to free bets with no stated wagering condition is not established in the Commission’s published rules.

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

Minimum odds are the floor on the qualifying bet: Coral and Unibet’s “min odds 2.0” means the £20 qualifying bet must be at odds of 1/1 or greater, not at 4/6 or 1/3. The wagering requirement is the turnover the bonus must be played through before it (or its winnings) becomes withdrawable. A £50 bonus at 10x means £500 of qualifying bets; a £50 bonus at 50x would have meant £2,500. Under the Commission’s cap, no GB bonus can require more than 10x.

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

A free bet is a non-refundable token, and the payout only includes the winnings at the odds taken, not the token’s own value. Betting a £10 token at 3.0 odds generates £20 in winnings, whereas a £10 cash bet at the same odds returns £30. This is the mechanism behind the discrepancy between “free £30” marketing and the £20 cash outcome.

Can a sports bet be tied to a casino bonus under the Commission’s rules?

No. The Commission’s promotion rules in force since 19 January 2026 ban mixed-product promotions: an offer that requires gambling on two or more product types (sports betting plus casino, for example “bet on football to get free spins”) is no longer permitted at a GB-licensed operator. Sports-only and casino-only offers are allowed; the bridge between them is not.

How can a bookmaker’s Gambling Commission licence be checked?

The Commission’s public register at the gamblingcommission.gov.uk domain can be searched by business name, trading name, domain or licence account number. The licence number on the operator’s own site should reconcile against the register: for example, Unibet UK shows account 45322 under Platinum Gaming Limited; Sky Bet shows its own account under SBG Sports Limited. A brand whose licence number cannot be reconciled is either offshore, misquoted, or licensed under a different entity than the one named on the site.
