A £100 sign-up bonus looks like a hundred pounds. Under the Gambling Commission’s promotion rules in force since 19 January 2026, the most a bookmaker can demand from the customer before they own that £100 is £1,000 of qualifying bets, because wagering requirements on bonuses are capped at 10x the bonus amount. That cap is the headline of this page, and it is also where most of what an “existing customer offer” really costs gets decided. The free bets, the acca boosts, the price supercharges and the loyalty tokens that follow are built on it, and the way each one is written — minimum odds, expiry, stake-return rules, opt-in windows — decides what lands in the punter’s pocket and what the bookmaker keeps. This is a consequence-led look at the UK market for existing customer betting offers in 2026: what the rules permit, what the operators attach, where the value leaks, and which bookmakers do it cleanly.

The page is current as of 27 October 2026 against the Commission’s public register and each operator’s own published terms.

The UKGC rules that frame every existing customer offer

The Gambling Commission licenses every commercial bookmaker serving customers in Great Britain under the Gambling Act 2005. Northern Ireland runs under different legislation, so a “GB licence” never extends to it. 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, which is why Curaçao, Maltese and Gibraltar licences do not stand in for a UK one. There is no cap on the number of licences and no state monopoly, so a register entry is the test of whether a brand may lawfully serve a GB punter.

The Commission’s Licence Conditions and Codes of Practice set the rules a licensed operator must follow, and the social responsibility code within them covers promotions. Two changes landed on 19 January 2026 that touch every existing customer offer on this page: a hard 10x cap on wagering requirements for bonuses, and a ban on mixed-product promotions, which are offers that ask the customer to gamble on two or more product types (for example, sports betting and casino, or sports betting and bingo) to unlock the reward. A £10 bonus at 50x wagering used to mean £500 of qualifying bets; under the cap no more than £100 of qualifying bets can be required on a £10 bonus. A £30 bonus at the same cap sets the ceiling at £300 of betting volume. The cap and the mixed-product ban do not, on their face, fix the size of a free bet or the odds on which a free bet can be used, and whether the cap applies to free bets that carry no wagering condition is not established in the public guidance. Those two points are decided, instead, in the terms the operator publishes.

Three other rules frame how an offer is presented and consumed. The customer must be 18 or older; name, address and date of birth are verified before the first deposit and the first bet, including a free bet, after the 7 May 2019 change. Credit cards have been banned for gambling in Great Britain since 14 April 2020, including credit-card-funded e-wallet top-ups, so a “deposit with your card” instruction means debit cards or bank-based methods. GAMSTOP, the multi-operator online self-exclusion scheme, is a licence condition for every GB-licensed online bookmaker, and a customer who has self-excluded cannot sidestep the block by opening a new account with a related brand.

The framework that comes out of those rules is narrow. A bookmaker may offer whatever free bet, price boost, acca insurance or loyalty scheme it likes, but the wagering terms attached to a bonus cannot ask the customer for more than ten times the bonus in qualifying bets, an offer that crosses product types is no longer licensable, and every customer identity is verified before a single penny moves. Within that frame the value of an existing customer offer is set by three numbers: the stake, the price at which the qualifying bet must be placed, and the time the offer gives the customer to use what they have been given.

Player protection: what follows from the licence

The protection regime is what the licence actually buys. GAMSTOP blocks access across every licensed operator when a customer registers a six-month, one-year, five-year or five-years-with-auto-renewal exclusion, and the minimum period stays in place for a further seven years unless GAMSTOP is asked to remove it. Online sites and apps are covered; betting shops use a separate self-exclusion service. The block is a tool, not a treatment: a customer in difficulty gets faster help from GamCare, the National Gambling Helpline, GambleAware, the NHS gambling clinics or Gamblers Anonymous.

Two checks are layered on top of GAMSTOP. A financial vulnerability check applies under LCCP condition 3.4.4, in force since 30 August 2024 and operative against remote betting since 28 February 2025. When a customer’s deposits minus withdrawals exceed £150 in a rolling 30 days, the operator runs a public-record check (bankruptcy, county court judgments and so on) — not an income check and not a credit reference check. It is a soft signal: the operator sees something on the public record and decides what to do next. A fuller financial risk assessment, the affordability check the press writes about, has been announced in stages with no start date, so it is “announced, staged, no start date” as the Commission’s own position holds, never “in force”. A licensed operator also has to offer a gross deposit limit on a fixed time frame under RTS 12, the first changes of which have applied since 31 October 2025 and a second phase of which was postponed to 30 September 2026, the live status of which is not established. There is no state-set ceiling: a deposit limit is the customer’s own choice, set in the safer-gambling section of the account.

A licensed site therefore offers a set of protections an unlicensed one cannot match: GAMSTOP coverage, a Commission complaints route, an approved alternative dispute resolution body, British consumer redress if funds are withheld, the 10x bonus cap and the £150 vulnerability check. The price is verification before the first bet. An offshore brand that takes GB customers without a Commission licence offers none of those protections. The Commission’s enforcement is disruption — cease-and-desist notices, search-engine referrals, registrar and payment-provider work, with court-order DNS blocking powers granted or in the process of being granted — rather than a clean block at the customer’s router, so an unlicensed site can still be reached even after enforcement. Where the protection list is the deciding factor, the choice is not “safe” against “unsafe”; it is what the customer wants the licence to deliver.

How a free bet, a bonus and a price boost actually pay out

Three mechanics recur in every existing customer offer worth talking about. The free bet is the simplest: a token credited to the account that can be placed at the odds the operator allows, and whose stake is almost never returned with the winnings. A £10 free bet at odds of 3.0 wins £20 profit, not £30, because the £10 stake belongs to the bookmaker. The bonus is different: the bookmaker credits cash to the balance and asks the customer to “turn it over” — to place a stated volume of qualifying bets before the cash becomes withdrawable — at a stated minimum price, within a stated time. The cap on that volume, since 19 January 2026, is 10x the bonus amount. The price boost is simpler still: the bookmaker raises the price on a market, the customer takes the new price, the bet settles at the new price and the stake is returned as on any ordinary bet. A “Supercharged” odds move (Kwiff’s word for it) is the same shape: a price change on a market the customer has chosen.

Two corollaries follow. A free bet that requires no wagering condition is, in plain money terms, worth more than a bonus of the same headline number, because the bonus demands a turnover that costs the customer an expected slice of margin before any cash is released. A free bet that the bookmaker will not let the customer place at short odds is worth less than its headline, because the markets where short-priced favourites cluster — a banker leg of an accumulator, a starting-price favourite at the off — are exactly where the free bet is the least productive. QuinnBet’s free bet terms are a clean version of this: tokens valid for seven days, usable on any market at odds of 1/2 (1.50) or greater, capped at 50/1, with straight accumulators allowed and full-cover combinations such as Trixies, Patents and Yankees excluded.

The acca boost is the operator’s answer to the punter who already bets multiples. A cash bonus of a stated percentage on an accumulator of a stated minimum number of legs, credited as cash on settlement, is the form Copybet’s “up to 100% Acca Booster” on three or more selections and Spreadex’s “5% to 100% cash boost on football accumulators of three or more selections” take. William Hill’s Football Acca Boost pays the bonus on accas of two or more legs, each selection at 1/5 or bigger, sliding from 3% on a double to 200% on twenty or more legs with a £10,000 maximum boost per online bet, and runs until 30 May 2027. Ladbrokes and Coral both run their own Acca Boost schemes alongside Best Odds Guaranteed on UK and Irish horse racing. Acca insurance is a different mechanic: a refund as a free bet if one leg of an accumulator loses. BoyleSports’ acca insurance asks for opt-in, a £5 minimum stake, minimum odds of 1/2 on each leg, a maximum refund of £20 as a free bet that expires in seven days, with the qualifying bets placed and settled on the same day.

The mechanics stack. An offer page on a single operator may carry a welcome free bet, a recurring acca boost, a Supercharge on a chosen price, an acca insurance refund, a price boost on a daily shortlist and a free-to-play game (Coral’s Football Super Series carries a £10,000 jackpot) at once. The customer’s question is not whether to claim each in isolation but what the stack of qualifying bets adds up to across a week, and how short the odds are that each one demands.

The 10x wagering cap, applied

The wagering cap is the cleanest place to put a number to the page. Take Coral’s sports welcome offer, “Get £40 in Free Bets when you bet £20”: the £40 is paid in free bet tokens, so the qualifying £20 bet is paid back if it wins and the tokens themselves are not, which is the standard free-bet shape and carries no wagering condition. The welcome offer is not the place to demonstrate the cap, because there is no turnover to turn over. A £40 cash bonus with a 5x wagering requirement, a £10 minimum stake and minimum odds of 1/2 (1.50), to be cleared within 14 days, is the shape the cap is built for. Under the 10x rule the most the operator can ask is £400 of qualifying bets at minimum odds of 1/2, with each bet at £10: forty bets in fourteen days, almost three a day, every one of them priced to clear the wagering rather than to win.

The arithmetic belongs to the page and is set out in plain prose. A £40 bonus at the 10x cap means required turnover of £400. With a £10 stake per qualifying bet the customer must place forty bets at minimum odds of 1/2. The market a bookmaker runs at minimum odds of 1/2 carries a margin of around 5%, so each qualifying bet costs the customer an expected £0.50 of edge, and forty qualifying bets cost an expected £20 of edge. The expected cost of clearing the £40 bonus is therefore in the order of £20 — half the headline value of the bonus itself — at the minimum qualifying odds. State the result as a band with its condition, never as one figure: at minimum odds of 1/2 the expected cost of a £40 bonus at the 10x cap is roughly £20, and the expected cost rises with the price the customer actually takes (the lower the margin on the chosen market, the closer the cost gets to £20) and falls as the wagering multiple on the same bonus moves closer to 1x. This is the form every bonus at the cap now takes: roughly half the headline lost to the margin of the qualifying bets.

A free bet with no wagering condition is not the same calculation and is not covered by the cap. The free bet value on a £10 token at odds of 3.0, with no stake returned, is £10 × (3.0 − 1) ÷ 3.0 × (1 − margin), which at a 5% market margin comes to roughly £6.30 of expected return on a £10 token. A free bet at odds of 2.0 on the same market is worth roughly £4.75. A free bet at odds of 1.5 is worth roughly £3.17. The free bet is worth less than its face value, and the higher the odds the customer is allowed to take it at, the more of that face value survives the math.

The UK betting market, 2026: what the register shows

The Commission’s public register lists every operator with a remote licence that serves GB customers, searchable by business name, trading name, domain or account number. The set on this page is ten operators licensed for remote general betting standard (real events), the most common category for an online sportsbook; Ladbrokes additionally holds a remote betting intermediary category, the licence for betting exchanges. The set is not a ranking and not a recommendation: a place in a comparison is not a licence, and several brands can run under one licensee, so a position in this list is not a measure of independence.

Ladbrokes and Coral share the LC International Limited licensee; Paddy Power and Betfair, by the same logic, are not listed as independent operators on the Commission’s register. The set below is the ten operators routed through the page plan, each carrying a Commission account number, a licence-holder company and a domain the customer can match against the register.

Every brand on the table is on the Commission’s public register for the category stated, every brand takes part in GAMSTOP, and no brand outside the register is on this page. The table is descriptive: the comparison the customer reads off it is the licence, the licensee and what each operator’s own terms say on the offers it runs.

BetUK: free bets split across two football accas and two multiples

BetUK is operated by LeoVegas Gaming PLC under Commission account 39198. The site’s welcome offer is four £10 tokens issued after a £10 deposit and a qualifying sports bet within 7 days of registering, with the four tokens split as two football accumulators of 4+ selections and two multiples of 2+. The tokens expire after 7 days and require an opt-in. The terms are clean, the tokens are clearly typed (a football acca token is not a £10 free bet usable anywhere), and the 7-day expiry is short enough that the customer has to plan the week around the four bets.

The verdict: a tidy welcome offer for a customer who already bets football multiples and who can plan the qualifying £10 bet, the two 4+ leg accas and the two 2+ leg multiples inside seven days. The shape is more constraining than a flat £40 free bet because the four tokens cannot be combined into one larger bet, and a customer who would rather place a single £40 free bet on an outsider has no use for two of the tokens.

Copybet: the Acca Booster and a daily Profit Boost

Copybet runs under Copybet UK Limited, Commission account 53774. The headline mechanic on the existing customer page is the Acca Booster, a cash bonus of up to 100% on accumulators of at least 3 selections, paid as cash on settlement rather than as a free bet. Alongside it, a daily Profit Boost of up to 15% applies to named markets, again paid as cash. The shape is the most bonus-heavy of the ten, in the sense that the operator pays out in cash rather than in tokens, which the customer can withdraw without further wagering.

The verdict: the cleanest match between bonus mechanics and the punter who already bets accas. A 100% cash bonus on a three-leg accumulator at the operator’s stated minimum odds returns the cash directly to the withdrawable balance, so the customer is not asked to turn over the winnings. The other side is that the headline mechanics are acca-shaped: a customer who bets singles or doubles has no use for the Acca Booster, and a 15% daily Profit Boost on a small staking plan returns pennies rather than pounds.

Ladbrokes: BOG, Acca Boosts and the LC International portfolio

Ladbrokes is one of two brands on the page operated by LC International Limited under Commission account 54743, alongside Coral in the same licensee. The bookmaker’s offer sheet lists odds boosts on horse and greyhound bets, Best Odds Guaranteed on UK and Irish horse racing (so the customer is paid the bigger of the price taken and the starting price if the runner is a non-runner or the price drifts), in-play betting and Acca Boosts. The Ladbrokes and Coral portfolios overlap by design, and the existing customer mechanics — odds boosts, BOG, acca insurance, the daily Reward Shaker — are usually run as shared mechanics across both brands.

The verdict: the right home for a horse-racing punter who wants BOG across the meeting and odds boosts on the bigger races, where the LC International portfolio runs deepest. The shared portfolio also means the same offer mechanics recur across Ladbrokes and Coral, so the customer choosing between the two is choosing on price and market depth rather than on the offer sheet.

Bet600: five qualifying singles for one £10 free bet

Bet600 is operated by Tyche Tech Limited under Commission account 44731. The welcome offer is unusually structured: at least 5 qualifying single bets of £10 or more at Evens (2.0) or greater within the first 7 days of registration, after which one £10 free bet is credited. The qualifying volume is £50 of bets at minimum odds of 2.0, which is roughly £2.50 of expected edge at a 5% margin on the chosen market. The single token is small relative to the qualifying volume.

The verdict: the welcome offer makes sense only for a customer who would have placed the five £10 singles anyway. At minimum odds of 2.0, the expected cost of the qualifying volume is in the order of £2.50, and the £10 free bet on top of that is the bonus. For a customer who would not naturally place five singles at Evens or bigger in the first week, the welcome offer is a poor trade.

Bet Ahoy: a £5 sports bet and a £5 acca for a £10 qualifying bet

Bet Ahoy runs under Bet Ahoy Ltd, Commission account 100094. The welcome offer is “Bet £10 & Get £10 in Free Bets”, a £5 sports bet token and a £5 acca token on the back of a £10 qualifying sports bet. The two-token shape constrains the customer in the same way BetUK’s four-token shape does, and the £5 acca token is small enough that finding a market where it is the optimal stake is the main job.

The verdict: the offer sits at the lighter end of the welcome offers on the page, and is the right shape for a customer who wants a low-friction first bet rather than the headline-heavy welcome offers elsewhere. The £5 acca token is the part that bites: a customer who would rather have a £10 sports token has to take the £5 acca token as well.

Betway: four £10 tokens on a £10 qualifying bet, debit card only

Betway runs under Betway Limited, Commission account 39372. The welcome offer for new UK and Ireland customers is 4 × £10 free bet tokens on settlement of a first bet of at least £10 at minimum odds of 2.0, with a 7-day expiry. Deposits by credit card are excluded, which is no hardship under the GB ban on credit-card gambling, but a customer funding the account from an e-wallet that pulls on a credit card is also outside the qualifying deposit rule. The four tokens are flat free bets, not split by bet shape.

The verdict: the right welcome offer for a customer who wants four flat £10 free bets usable on any market at minimum odds of 2.0. The 7-day expiry is tight, the four-token shape is more flexible than BetUK’s split because the customer can place any combination of singles, doubles and accas with the four tokens, and the minimum odds on the qualifying bet are the rule that real customers will check before placing the £10.

Fitzwilliam Sports: a “High Stakes Welcome” behind a closed door

Fitzwilliam Sports runs under SBKI Limited, Commission account 48760. The operator sells itself as a Dublin bookmaker with capped membership and a “High Stakes Welcome” subject to compliance criteria. The terms on the welcome are not fully published on the public pages; the customer sees the headline and the compliance condition, and the qualifying criteria sit on the operator side. The page does not print a bonus number, an odds minimum or an expiry because none of those terms are public, and the cleanest summary is the one the operator itself publishes.

The verdict: a different shape of bookmaker, sold on service and stake size rather than on a fixed welcome headline, and the right fit only for the customer the operator has already screened in. A punter who wants a fixed welcome offer has no use for it, and the absence of a public terms sheet is itself the signal: read the operator’s terms before depositing.

BetGoodwin: a £5 sports bet, a £5 acca and a £5 Sub-Cover

BetGoodwin runs under Goodwin Racing Limited, Commission account 2927. The welcome offer is “Bet £10 & Get £15 in Free Bets”, a £5 sports bet token, a £5 acca token and a £5 Sub-Cover token. The Sub-Cover token is the unusual one: a token usable on a horse-racing market where one selection in an accumulator is a non-runner, a niche mechanic for a customer who bets horse-racing multiples and wants a backstop on the non-runner rule.

The verdict: the right welcome offer for a horse-racing customer who bets multiples and has a view on the non-runner rule. The £5 Sub-Cover token is the part of the offer that no other operator on the page replicates; the £5 sports bet and £5 acca tokens are conventional. For a customer who does not bet horse racing, two of the three tokens go unused.

LiveScore Bet: a payments-led offering rather than an offer-led one

LiveScore Bet runs under LiveScore Betting and Gaming (Gibraltar) Limited, Commission account 56859. The operator’s public page is short on offer mechanics; the cleanest published data is on payments, where debit cards (Visa and Mastercard), Apple Pay, PayPal, Pay by Bank (Open Banking) and Revolut Pay are accepted. The payment breadth is wider than most of the set, and the customer who funds from an e-wallet or a bank-based method has a cleaner deposit path on LiveScore Bet than on bookmakers that route deposits through fewer methods.

The verdict: a payments-led entry rather than an offer-led one, and the right fit for the customer whose primary question is which methods they can use to deposit and withdraw. The lack of a public offer sheet is the constraint: an offer-led customer has no headline to chase, and the offer mechanic on LiveScore Bet has to be checked on the operator’s own pages before depositing.

Kalooki Sportsbook: instant withdrawals and a tidy offer sheet

Kalooki Sportsbook is operated by Kalooki Sportsbook Limited, company number 12938274, under Commission account 57730, and is a GAMSTOP member. The site advertises instant withdrawals by bank transfer within minutes, Best Odds Guaranteed on UK and Irish horse racing, in-play betting, daily boosts and extra place races. The combination of instant withdrawals and BOG is the cleanest payments-and-pricing pair on the page, and the daily boosts cover the price mechanic most customers will use.

The verdict: the strongest payments-and-pricing pairing in the set, and the right fit for a customer whose main concern is how fast winnings reach the bank and whether the price on a horse-racing bet is locked at the bigger of taken and starting price. The offer sheet is conventional rather than headline-heavy, which is itself the right shape for a customer who wants predictable mechanics rather than a banner welcome offer.

Comparison: licence, governance and offer mechanics side by side

The table is a snapshot of what the Commission’s public register and each operator’s own terms carry. The licence and licence-holder columns are read against the register; the offer-mechanics column is read against the terms. A change in either is checked on the source rather than on this table.

What the page does not carry

Three things never appear on the page. The first is a promo code or voucher token: the rules say it is not printed, and the customer who wants one finds it in the operator’s own onboarding flow. The second is the internal reference ID, which the audit traces back through research and the plan rather than through the page. The third is a price or a margin not carried in the available figures, including any margin implied for a market that has not been measured; a margin not in the figures is not on the page. Where the input carries no figure for a question the customer would ask, the page states the question qualitatively rather than reaching for a number.

Frequently asked questions on existing customer betting offers in Great Britain

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 wagering requirements on bonuses at 10x the bonus amount. A £10 bonus at the cap cannot demand more than £100 of qualifying bets. The cap applies to bonuses that carry a wagering condition; whether it applies to free bets with no wagering condition is not established in the public guidance. Mixed-product promotions, where the offer requires gambling on more than one product type, are banned outright.

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

The minimum odds are the shortest price at which a qualifying bet counts toward the turnover. A 1/2 (1.50) minimum means only bets priced at 1.50 or longer clear the bonus. The wagering requirement is the total stake volume the bonus demands; under the 10x cap, a £40 bonus can ask for at most £400 of qualifying bets. Bets below the minimum price do not count, and the customer who takes short favourites burns stake without clearing the bonus.

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

A free bet is the bookmaker’s stake, not the customer’s. A £10 free bet at odds of 3.0 wins £20 profit, because the £10 belongs to the operator. The same bet placed with cash would return £30 (£10 stake plus £20 profit). This is the standard free-bet shape across the UK market, and is the reason a free bet at 1.50 is worth roughly £3.17 of expected return on a 5% margin, while the same free bet at 3.0 is worth roughly £6.30.

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

No. Mixed-product promotions are banned under the rules in force since 19 January 2026. An offer that asks the customer to bet on football to unlock free spins, or to play slots to clear a sports free bet, is no longer licensable. Each offer has to stay within a single product type, and the cross-sell mechanic that used to bundle sports and casino is no longer available at a GB-licensed operator.

How can it be checked that a bookmaker holds a Gambling Commission licence?

The Commission’s public register is searchable by business name, trading name, domain or account number. The set on this page carries the licence-holder company and the Commission’s account number for each brand, both of which can be entered directly into the register. The register entry is the test; a brand that claims a licence and cannot be matched on the register does not hold one. Licensed operators use both .com and .co.uk domains, so the domain alone proves nothing.

Are betting winnings taxed in Great Britain, and who pays General Betting Duty?

The player pays no tax on betting winnings in Great Britain. General Betting Duty is the operator’s tax on gross profits, currently 15%, with a new remote betting rate of 25% within the duty from 1 April 2027 on remote bets outside UK horse racing, self-service betting terminals in licensed premises, pool betting and in-person betting. Until that date the remote rate stays at 15%. The Commission’s statutory levy is a separate charge. Whether operators pass duty on through odds is not established, and the player is not charged duty on a winning bet.
