A promo code unlocks nothing on its own. The number that decides whether an offer is worth claiming sits two lines below the headline — the wagering multiple, the minimum odds and the expiry — and that number is what the page below is about. The landscape changed on 19 January 2026, when the Gambling Commission brought in two rules that every welcome bonus, free bet and “risk-free” promotion at a British bookmaker now has to obey. Reading the small print without those rules in mind is how a £40 headline becomes a £9.50 effective free bet before the offer expires. This guide works through what the rules mean, what each operator’s own terms add on top, and where the arithmetic of an offer turns a generous headline into a costly one.

*Data current as of 27 October 2026, checked against the Gambling Commission’s public register and each operator’s own published terms.*

How a bookmaker promotion actually works

A promotion is a contract. The headline number is what you receive; the small print is what you have to do to keep it. Four numbers decide almost every offer a licensed British bookmaker runs in 2026:

• The trigger. What you have to do to qualify — usually deposit a set amount, place a qualifying bet at or above a minimum odds line, or both. Coral’s £40 free-bets headline is unlocked by a £20 bet at minimum odds of 2.0 (1/1); Sky Bet’s £30 is unlocked by a £5 deposit and a 5p first bet at odds of 1/1 or greater.
• The reward. What you actually receive — £30, £40, four £10 tokens, a stake-matched free bet, a percentage boost on an accumulator. The headline figure is always the reward, never the trigger.
• The wagering requirement. How many times the bonus (or the bonus plus deposit, depending on the operator) must be turned over before any winnings can be withdrawn. Coral and Unibet publish offers whose bonus terms require staking the bonus a fixed number of times at or above minimum odds before cashing out.
• The clock. When the reward expires — Coral’s free bets are valid for 7 days from issue; BoyleSports’ acca refunds expire in 7 days; Betway’s free bet tokens expire in 7 days.

Stakes returned or not? Most free bets and bonus stakes are not returned with the winnings. A £10 free bet at odds of 3.0 wins £20 profit, not £30; a £40 free-bet bundle is £40 of stakes the bookmaker gave you free, with the winnings paid in cash but the £40 itself never coming back. Stake-not-returned is the default in British online betting, and any operator’s headline that does not state otherwise follows that default.

The 10x rule and the mixed-product ban, since 19 January 2026

Two promotion rules landed at every British online bookmaker on 19 January 2026. The first sets a hard ceiling on the wagering multiple: no licensed operator can require a customer to wager a bonus more than ten times before withdrawal. The second bans mixed-product promotions — offers that require gambling across two or more product types, such as “place a football bet to unlock free spins” or “wager on sports to release a casino bonus.” Both are Gambling Commission licence conditions, sitting inside the LCCP, and they are not negotiable at the counter.

The 10x cap is the number that reshapes the arithmetic of every headline. A £10 bonus that once carried a 50x requirement meant £500 of qualifying bets before withdrawal; under the cap, no more than £100 of qualifying bets clears any £10. Where the old shape was a punishing 40x or 50x attached to a small bonus, the new shape is shorter turnovers with bigger qualifying stakes. Free bets whose stake is returned in cash on a win are unaffected — there is no wagering requirement to multiply, just a single bet at minimum odds.

What the cap does not establish is whether it applies to free bets with no wagering condition at all. Free bets issued as a fixed-value token with no rollover attached (Sky Bet’s £30 in three £10 tokens, BetUK’s four £10 tokens, Betway’s four £10 tokens, Hollywoodbets’ stake-back-as-free-bet refund) sit outside the rule by structure rather than by exemption — there is nothing to multiply, because there is no wagering requirement. The cap is a ceiling on the multiplication, not on the offer’s headline size, and it does not say how big a free-bet bundle can be.

The mixed-product ban is the easier of the two to spot. If an offer rewards you for betting on football and hands out free spins, online bingo tickets or lottery entries, it cannot be marketed to British customers. The rule forces product separation: sports welcome offers live on their own, casino welcome offers live on their own, and an existing-customer promotion cannot bundle two product types into one reward. For a punter, the practical effect is that a welcome offer stating “deposit £20, bet £20 on sport, get £40 in free bets” is now the cleanest shape on the market — the operator is staying on the right side of the rule by keeping the offer inside one product.

What a wagering requirement costs in real bets

The arithmetic of a wagering requirement is simple to write and punishing to clear. Assume a £10 bonus with a 5x wagering requirement at minimum odds of 1.5 (1/2) decimal 1.50. The required turnover is £50. At a £5 stake per qualifying bet, that is ten bets. Each bet at 1.5 wins £2.50 profit on a £5 stake, but no bet is guaranteed to win, and losing bets count toward turnover only at operators that allow them — many count only winning bets, which extends the run considerably. The bookmaker’s margin sits inside every odds line: the 1.5 minimum line across a typical 1X2 market carries around a 7-8% margin, so the £50 turnover costs the punter roughly £3.50 to £4 of expected value before any cash is withdrawn.

Under the 10x cap, that same £10 bonus has a £100 turnover ceiling. Ten £10 bets at 1.5 minimum odds clears the bonus, with an expected cost in the £7 to £8 range. The cap does not abolish the cost — it caps the multiplication that produces it. A punter choosing between a £10 bonus at 5x and a £50 bonus at 5x is choosing between £50 and £250 of qualifying bets, with the larger headline carrying five times the expected loss.

The Qualifying Bet versus the Free Bet distinction matters. A qualifying bet is paid for in your own cash, settled at the bookmaker’s normal odds, and any winnings come back to your withdrawable balance. A free bet is paid for in bookmaker credit, settled at the same odds, and the stake is not returned. Reading the offer as one number ignores that the two bets behave differently on the way out — the free bet wins profit only, while the qualifying bet wins the full return.

What minimum odds actually filter

Minimum odds in an offer are not a customer-protection rule. They are a margin filter. The bookmaker sets minimum odds at a line that excludes the safest bets on the board, where the margin is thinnest and the bookmaker’s edge is hardest to recover, and forces the punter toward markets with a fatter margin. A 1.5 (1/2) minimum odds line excludes any heavy favourite at very short odds — these are the bets on which the punter would otherwise be tempted to grind through turnover. A 2.0 (1/1) minimum odds line, as Coral and Unibet require for their £20 qualifying bet, excludes everything below evens, leaving a punter to find mid-priced markets where the bookmaker’s edge is structurally larger.

The filter does not filter the punter out of the offer — it filters the punter into a less profitable style of betting. Turnover at minimum odds is more expensive than turnover at any-price. Where an offer allows any market, the punter’s expected cost is the book’s average margin across the markets they actually bet on. Where an offer restricts to minimum odds, the expected cost converges on the margin of those specific markets.

Free bet stake-not-returned: why the £10 token is not £10 of value

The single most expensive misunderstanding in British promo terms is treating a £10 free bet as £10 of cash. A free bet token is a credit that pays profit only on a win: a winning £10 free bet at odds of 4.0 (3/1) returns £30 profit, not £40. The £10 stake is the bookmaker’s contribution and stays with the bookmaker whether the bet wins or loses. A £10 free bet placed at long odds on a market with a thin margin is worth more in expected value than a £10 free bet placed at short odds on a fat-margin market, but neither is worth £10 of real money.

Two pieces of arithmetic follow from that. First, the headline size of a free-bet bundle is not its cash value — a £40 free-bet bundle issued as four £10 tokens is worth something less than £40 in expected terms, depending on the markets the punter uses the tokens on. Second, a stake-returned free bet, where the stake is added back to winnings on a win, is materially more valuable than a stake-not-returned free bet at the same headline size. The difference between the two is the entire stake of the bet, and operators are not obliged to make stake-returned the default.

Some operators publish a stake-returned bonus in their welcome offer. Most do not. The published headline figure is the token value, and the punter’s working assumption should be that stake is not returned unless the small print says so.

The shelf of welcome offers at British bookmakers in 2026

The shape of a welcome offer at a British bookmaker in 2026 falls into a small number of templates. Most fit one of four:

• Stake-matched free bets. Deposit and bet a set amount, receive free bets of equal or larger headline value. Coral’s £40 in free bets for a £20 qualifying bet, Unibet’s identical headline, Sky Bet’s £30 in three £10 tokens for a 5p first bet — all variants of the same shape.
• Stake-back-as-free-bet on a losing first bet. Stake £10 or more on an accumulator of three or more legs at minimum odds; if the bet loses, receive the stake back as a free bet. Hollywoodbets’ welcome offer is the cleanest published version of this template.
• Multiple free-bet tokens on a first bet. Four £10 tokens, usually with two tokens restricted to football accumulators and two to multiples on other sports, as RestBet UK’s published terms describe.
• Token-and-bonus hybrids. Some welcome offers stack free bets with a percentage bonus or matched deposit on top of the qualifying bet. These are rarer at British sportsbooks since the mixed-product ban, because a percentage bonus tied to a free-bet reward was a common mixed-product trigger.

Reading the headline as a template tells a punter where the costs sit. Stake-matched offers carry the cost in the qualifying bet — the £20 bet that unlocks £40 of free bets has to win or lose on its own merits, and the £20 is at risk. Stake-back offers carry the cost in the accumulator structure — the first bet has to lose for the free bet to fire, and accas are higher-margin markets than singles. Multiple-token offers carry the cost in the token restrictions — two of the four £10 tokens locked to a 4+ leg football acca are usable only on high-margin markets.

The ten licensed operators in this comparison

The ten brands in this comparison hold a Gambling Commission remote licence for real-event betting at the snapshot date. They are not a ranking; a position in the list reflects the order this guide covers them in, not a measure of who is best. Each is a separate licensee unless the Commission’s register names the same operating company behind two brands, which it does not here — every brand on the list is operated by a distinct Commission account holder. Every brand participates in GAMSTOP. Every brand is subject to the LCCP marketing conditions, the 10x bonus cap and the mixed-product ban. Every brand verifies identity before the first deposit, and none of them accepts anonymous play.

A licence is not an endorsement. The Commission licenses operators to take bets in Great Britain; it does not certify that any one operator’s promotion is the best value for any one particular punter. Reading the licence number is a check that the operator is answerable to a British regulator and that the Commission’s complaints route is open if funds are withheld. It is not a check that the headline figure on the offer is the figure the punter keeps.

Unibet — the platform for the established punter

Unibet’s UK site has been live since 1999, operated by Platinum Gaming Limited under Commission account 45322. The sports welcome offer for new GB customers is “Get £40 in Free Bets when you bet £20” — a deposit and sports bet of £20 or more at minimum odds of 2.0 (1/1), with the free bets expiring within seven days of issue, and the qualifying payment restricted to a debit card or instant bank transfer.

Beyond the welcome, Unibet publishes Bet Builder, daily Uniboosts, live streaming through Unibet TV, in-play betting across most major sports, Best Odds Guaranteed on horse racing and Cash Out on thousands of markets. The features list is one a punter who already knows which markets they bet on can lean into: the horse-racing BOG terms, the live-streaming catalogue and the Cash Out ceiling are all features that pay off for a punter with a settled betting routine.

For whom: the punter who bets on horse racing and wants BOG, who uses Bet Builder across multiple events, and who values in-play streaming. This is a solid, mid-market welcome, though the seven-day expiry on the free bets is tighter than some rivals.

Paddy Power — the platform for novelty markets and money-back specials

Paddy Power is operated by PPB Counterparty Services Limited under Commission account 39439. The brand’s published app features 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.

Paddy Power is the brand a punter associates with novelty specials — money-back if a named player scores two, refund on a late goal, price boosts on unusual markets. The Super Sub feature in particular is a structural rule that pays out on bets a substitution would otherwise void, and that rule is built into the bet’s odds rather than tacked on as a promotion.

For whom: the football punter who bets on goalscorer markets, the punter who wants a substitution-safety net, and the punter who likes novelty specials. The headline offer is best understood as a gateway to the brand’s recurring promotions, rather than a standalone sign-up package.

Copybet — the platform for accumulator specialists

Copybet is operated by Copybet UK Limited under Commission account 53774. The app advertises an Acca Booster that pays up to a 100% cash bonus on accas of three or more selections, and a Daily Profit Boost of up to 15%.

Copybet is built around the accumulator. The Acca Booster is paid as cash, not as free-bet credit — that matters because a cash bonus is withdrawable on settlement, whereas a free-bet bonus has its own wagering terms. The Daily Profit Boost applies to single bets and multiples, and stacks on top of the acca booster where the bet’s structure allows.

For whom: the punter who places accas regularly and wants the payout on those accas boosted in cash rather than in free-bet credit. It is less compelling for a punter who primarily bets on single markets, as the booster logic is tuned for multi-leg tickets.

London Bet — the platform for the London-centric book

London Bet is published by Thistle Bet Limited under Commission account 66162 and is licensed for remote general betting in Great Britain. The app carries a 17+ age rating in the App Store.

The brand’s identity is local to London racing and football markets. A punter looking for a brand that visibly leans into the London racing calendar will find London Bet shaped for that. A punter looking for a broad in-play catalogue across international sports may find the brand narrower than the bigger names.

For whom: the London-based punter with a focus on UK racing and the capital’s football clubs. Less suited to the punter who wants a deep in-play catalogue across tennis, basketball and US sports.

Betway — the platform for the £10-first-bet punter

Betway is operated by Betway Limited under Commission account 39372. The sports welcome offer for new UK and Ireland customers is £40 in free bet tokens issued as four £10 tokens, credited on settlement of a first bet of at least £10 at minimum odds of 2.0 (decimal 2.00), with a seven-day expiry and debit card deposits only.

The headline shape is the four-token model: four £10 free bets to use across the catalogue. A punter who plans to spread the tokens across four different events or markets gets the full value of the structure. A punter who places one large bet and lets three tokens expire gets a fraction of the headline.

For whom: the punter who wants four separate free-bet tokens to deploy across a week, with debit-card deposits as the qualifying path. If you prefer e-wallets or instant bank transfers, note that these payment methods do not qualify for the welcome offer.

10bet — the platform for the matched-deposit punter

10bet is operated by Blue Star Planet Limited under Commission account 43173. The app advertises a 100% up to £50 betting bonus for UK sign-ups, plus daily free bets and free spins.

The headline shape is the percentage bonus rather than the free-bet token: deposit and bet a qualifying amount, receive a matched bonus of up to £50. A punter reading the offer as a £50 free bet is reading it wrong — the offer is a matched bonus with its own wagering terms.

For whom: the punter who prefers a matched-deposit shape to a stake-matched free bet, and who reads percentage bonuses as cash rather than as bet credit. This is a different offer structure compared to the standard token-bundle welcome packages found elsewhere.

BetVictor — the platform for the existing-customer punter

BetVictor is operated by BV Gaming Limited under Commission account 39576. The app advertises regular price boosts, acca offers and free bets on selected events, with welcome offers shown in the app and governed by the customer terms and conditions.

BetVictor’s marketing emphasis is on existing-customer promotions rather than a single headline welcome offer. A punter who already has an account and bets regularly is the brand’s target — the daily boosts and acca offers are the recurring value, and the welcome offer is one element in a longer relationship rather than the entire pitch.

For whom: the punter who values recurring boosts and acca promotions over a single headline welcome. Less suited to a punter who is choosing a bookmaker primarily on the size of the sign-up package.

Hollywoodbets — the platform for the acca-first-bet punter

Hollywoodbets is operated by Hollywoodbets International UK Limited under Commission account 53028. The sports welcome offer is stake-back-as-free-bet on a losing first accumulator: new players who deposit £10 or more by card receive their stake back as a free bet of up to £30 on their first qualifying losing accumulator, with a £10+ stake, three or more legs, minimum odds of 4/1, settled within seven days, and one free bet per customer.

This is the cleanest stake-back template on the British market. The first bet has to lose for the free bet to fire, the structure requires an accumulator rather than a single, and the maximum free bet is £30. A punter who plans to place a £10 first acca at 4/1 or longer anyway is the natural audience — the welcome offer is built into the bet they were already going to place.

For whom: the acca punter placing a first bet at 4/1 or longer who wants stake-back protection. This offer is clearly designed to incentivise the first accumulator, so singles-focused punters will find it less relevant.

BetUK — the platform for the structured-token punter

BetUK is operated by LeoVegas Gaming PLC under Commission account 39198. The sports welcome offer is four £10 free bets (two football accas of four or more selections and two multiples of two or more) for new customers who deposit £10 or more and place a sports bet within seven days of registering, with opt-in required and a seven-day token validity.

The four-token structure is split: two tokens locked to football accas of four or more legs, two locked to multiples of two or more legs across other sports. The structure forces a particular kind of punter behaviour — a punter who bets mostly on football singles will not be able to deploy the football-acca tokens naturally and may leave them to expire.

For whom: the punter who already bets on football accas of four or more legs and on multiples across other sports. Less suited to a punter whose betting is mostly singles.

Sky Bet — the platform for the small-trigger punter

Sky Bet is operated by SBG Sports Limited under Commission account 67370. The welcome offer for new customers is £30 in free bets, credited as three £10 free bet tokens after a deposit of at least £5 and a first single or each-way bet of at least 5p at minimum odds of 1/1.

The trigger is the smallest on this list: a 5p first bet at evens or above, on a £5 deposit, unlocks £30 of free bets. A punter who wants to claim a welcome offer without committing a large qualifying bet has the lowest barrier to entry here. The three-token shape is a smaller bundle than the four-token offers, but the trigger is correspondingly smaller.

For whom: the punter who wants the smallest possible qualifying stake. Less suited to a punter looking for the largest headline figure — £30 is below Coral’s and Unibet’s £40.

A side-by-side view of the ten welcome offers

The table reads the offer terms as the operators publish them, with the licensing data drawn from the Commission’s public register. The “key condition” column is the term that most shapes what the punter actually receives — minimum odds, qualifying stake, expiry, or token restriction.

A few patterns sit across the columns. Three operators — Coral, Unibet and Sky Bet — publish a stake-matched free-bet welcome at £40, £40 and £30 respectively; BetUK and Betway publish four-token welcome offers; Hollywoodbets publishes a stake-back offer; 10bet publishes a percentage bonus. The triggering stake ranges from 5p at Sky Bet to £20 at Coral and Unibet. The minimum odds range from evens (1/1) at Sky Bet to 4/1 at Hollywoodbets. The token validity sits at seven days for the operators that publish a window.

Existing-customer promotions, not just the welcome

The welcome offer is one promotion in a longer relationship. The bulk of an operator’s promotional spend sits with existing customers, and the headline figure on the welcome is rarely the largest offer the punter sees over a year of betting. Five shapes recur in British existing-customer promotions:

• Odds Boosters. A boost on a specific price, applied to a single bet or a short list of bets, sometimes capped at a maximum stake. Coral’s Odds Booster runs on hundreds of markets; BetVictor’s daily boosts run on selected events; Paddy Power and Sky Bet publish boosted prices through their apps.
• Acca Insurance. A refund as a free bet if one leg of an accumulator of a specified minimum size loses. BoyleSports’ Acca Insurance requires opt-in, a £5 minimum stake, minimum odds of 1/2, pays a maximum refund of £20 as a free bet expiring in 7 days; Spreadex’s acca boost pays a cash boost from 5% to 100% on football accas of three or more legs, depending on the number of legs.
• Acca Boosts. A percentage boost applied to winning accumulators, often tiered from a low percentage at three legs to a higher percentage at longer accumulations. William Hill’s Football Acca Boost runs from 3% on a double up to 200% on twenty or more legs, with a maximum boost of £10,000 per online bet and running until 30 May 2027.
• Profit Boosts. A token that boosts the winnings of a bet at a specified minimum odds, applied as a one-off. Copybet’s Daily Profit Boost of up to 15% is the published version; Kwiff’s Supercharge feature can instantly boost the odds on a bet from 2/1 to 20/1.
• Free-to-play games. Operator-run prediction games with a published prize. Coral’s Football Super Series offers a £10,000 jackpot free to enter; the structure is a free-to-play game with a small-stakes entry, separate from the betting wallet.

These are the promotions that pay back over a year. A welcome offer is a one-shot headline; existing-customer promotions are the recurring value. A punter choosing a bookmaker on welcome size alone is reading only one page of the contract.

Bet Builder, Cash Out and the feature shelf

Three product features now sit on the comparison list for almost every British bookmaker, and each has a cost the punter should price in.

Bet Builder lets a punter combine multiple markets from one event — or, in the “Bet Builder+” version that several operators publish, multiple Bet Builder selections across different games — into a single bet. The odds multiply across the legs, and the margin compounds. A two-leg Bet Builder at 1.8 and 1.7 carries more margin than either single bet alone, and the punter’s expected cost of the bet is higher than the simple product of the odds. Bet Builder is convenient; it is not cheap.

Cash Out settles a bet before the event has finished, at a price set by the operator. The price the operator offers reflects the live state of the markets and the operator’s margin on those markets; the punter is taking a price from a bookmaker who can move that price instantly. Cash Out availability is not guaranteed — DAZN Bet’s published terms state that cash out availability is not guaranteed and bets stand if it is unavailable. A punter relying on Cash Out to manage a position is taking a position against an operator who sets the price.

Best Odds Guaranteed is a horse-racing feature where the operator pays the starting price if the starting price is higher than the price the punter backed at. Unibet publishes BOG on horse racing; the punter’s protection is against the operator moving the price down between bet placement and the off. BOG does not protect against the operator’s normal margin; it protects against the specific case where the operator’s price drifts between bet and race.

Payments, the London acca and the credit-card ban

Credit cards are banned for gambling in Great Britain since 14 April 2020, including credit-card-funded payments through an e-wallet. Debit cards, instant bank transfers and the major e-wallets are not covered by the ban. Several operators’ published terms exclude credit cards explicitly — Coral’s welcome offer must be qualified with a debit card or instant bank transfer; Betway’s qualifying payment is a debit card deposit.

This matters because a punter whose preferred payment method is a credit card cannot qualify for a welcome offer at a bookmaker that excludes credit cards from the trigger. The ban is not the operator’s choice; it is a Commission licence condition. A punter using an e-wallet funded by a credit card falls under the same rule — the source of the funds is the test, not the wallet.

The minimum-deposit and maximum-stake rules are operator-specific and not Commission requirements. The Commission does not list maximum stakes, and a punter planning a large bet should check the operator’s own published terms.

Identity verification before the first deposit

Every licensed British bookmaker verifies name, address and date of birth before the customer can deposit or gamble — a rule in place since 7 May 2019, and applying even when the first interaction is a free bet or bonus. The verification is not optional. A punter who wants anonymity does not have it at a licensed operator; the alternative is an offshore site without the British protections — no GAMSTOP coverage, no Commission complaints route, no approved dispute resolution, no British consumer redress if funds are withheld.

The trade-off is real and the page should name it. A licensed operator means verification, but it also means a regulator behind the operator, a self-exclusion scheme that follows the customer across brands, and a complaints route if funds are wrongly withheld. An unlicensed operator means none of those protections, and the punter’s only recourse is the operator’s own customer service — which is the same party that withheld the funds in the first place.

The Commission’s promotion rules, written in full

The Gambling Commission’s LCCP conditions on marketing and promotion run to several pages; the two rules in force since 19 January 2026 are the ones that reshaped the welcome-offer market.

The wagering cap is the headline: no licensed operator can require a customer to wager a bonus more than ten times before withdrawal. The rule applies to the bonus itself and to any bonus-plus-deposit structure, and the cap is on the multiple, not on the bonus amount. A £50 bonus at 10x is £500 of qualifying bets; a £100 bonus at 10x is £1,000. The cap is on the multiplier.

The mixed-product ban prohibits offers that require gambling on two or more product types — betting, casino, bingo and lottery are the four product categories the Commission names. “Bet £20 on football to get 50 free spins” is the textbook banned structure. The ban does not prohibit a casino-only welcome offer; it prohibits a welcome offer that crosses the product boundary. Operators have responded by separating sports and casino welcome offers and by removing the cross-product trigger from existing-customer promotions.

What the rules do not establish is a cap on the money value of a bonus. A £1,000 welcome bonus at 10x is a £10,000 turnover requirement and is permissible under the rule; a £10,000 welcome bonus at 0.5x is a £5,000 turnover requirement and is also permissible. The cap is on the multiplier, and operators are free to set headline sizes below or above any informal market norm.

What the £150 vulnerability check actually does

Since 28 February 2025, licensed remote operators have run a financial vulnerability check when a customer’s deposits minus withdrawals exceed £150 in a rolling 30-day period. The check is a public-record check — bankruptcy, county court judgments, IVAs, debt relief orders — not an income check and not a credit reference check. The Commission named this specifically to avoid confusion with the press’s “affordability checks” — those are the next-stage financial risk assessments, announced in a staged plan in a Commission article of 7 July 2026 with no start date.

The £150 threshold is a Commission rule, not an operator rule. A customer whose rolling 30-day net deposits stay below £150 does not see the check at all. A customer crossing the threshold sees a public-record check on the next deposit or transaction. A customer whose check returns adverse results may have deposits limited, accounts restricted, or further checks requested — the operator’s response is governed by its own social-responsibility code, and there is no published Commission-mandated outcome beyond the requirement to run the check.

The check is not a tax. It is not a fee. It is a record check, run by the operator or a third-party provider, paid for by the operator, and triggered at a Commission-set threshold. For most punters, the check is invisible — the £150 threshold catches only a fraction of accounts, and the public-record check returns a result the punter already knows. For a punter with adverse records, the check is the moment an operator may ask for source-of-funds information under the money-laundering rules.

Responsible gambling tools at every licensed operator

Every licensed British bookmaker runs the same shelf of responsible-gambling tools, and the shelf is not the operator’s choice:

• Deposit limits. A customer-set limit on the gross deposit over a fixed time frame, set in the account settings. The first changes to deposit limits have applied since 31 October 2025; a second phase has been postponed to 30 September 2026, and whether it is live at this snapshot is not established. There is no state-set deposit ceiling; the limit is the customer’s choice, and the operator must honour it.
• Loss limits. A customer-set limit on net losses over a fixed time frame.
• Wagering limits. A customer-set limit on the total amount staked over a fixed time frame.
• Time-out. A short break from the account, from 24 hours to several weeks.
• Self-exclusion via GAMSTOP. A multi-operator online self-exclusion, periods of six months, one year, five years, or five years with auto-renewal. After the minimum period the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it. GAMSTOP covers online sites and apps; betting shops use a separate service.
• Reality checks. Pop-up reminders of session duration at operator-set intervals.

Help is available outside the operator: GamCare runs the National Gambling Helpline; GambleAware signposts treatment; the NHS runs gambling clinics; Gamblers Anonymous runs peer-support meetings. A punter who feels their betting has moved beyond the recreational should reach for one of these before the operator’s own tools. The operator’s tools are effective; the external help is broader.

Tax, the player side

The punter pays no tax on betting winnings in Great Britain. This is general information, not tax advice — a professional gambler should ask HMRC or an adviser, because the line between recreational and professional gambling is a tax-line, and HMRC draws it from the facts of each case. For the recreational punter, the position is clean: keep the winnings, no tax to declare.

The operator pays General Betting Duty on gross profits, currently 15%. From 1 April 2027 a new remote betting rate of 25% applies within it, while remote bets on UK horse racing, bets on self-self-service betting terminals in licensed premises, pool betting and in-person betting stay at 15%. The change is to the operator’s tax bill, not the punter’s. Whether operators pass duty on through odds is not established, and the page does not claim the punter is charged duty.

The Commission’s statutory levy is a separate charge. It funds the regulator and is not a tax on the punter. A punter reading a “fee” or “levy” on a bookmaker’s bill should check which charge it is.

Offshore, and what a Curaçao brand does not give you

A Curaçao, Maltese or Gibraltar licence is not a substitute for a Commission licence. The point-of-consumption rule — an operator whose remote facilities are used in Great Britain needs a Commission licence wherever it is based — has been in force since the Gambling (Licensing and Advertising) Act 2014, amending sections 33 and 36 of the Gambling Act 2005. An offshore brand offering bets to a British customer without a Commission licence is the operator at fault, not the customer; the offence under section 33 of the 2005 Act carries up to 51 weeks’ imprisonment, a fine up to level 5, or both (six months in Scotland), aimed at the operator.

The customer loses the British protections if they bet on an unlicensed site: no GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld, not bound by the 10x bonus cap or the £150 vulnerability check. The customer does not commit an offence by betting on an unlicensed site, but the customer cannot reach a British regulator if the operator fails. “Legal to use” is the wrong framing; “unprotected” is the right one.

Enforcement is disruption, not blocking. The Commission issues cease-and-desist notices, refers search results, works with registrars, hosts and payment providers, and has been given, or is about to receive, court-order DNS blocking powers. The Commission does not run ISP-level blocking; a British punter reaching an offshore site has reached it through a path the regulator has not closed, and the regulator’s recourse is to chase the operator, not the customer.

A worked calculation: what a £40 free-bet welcome offer is worth

Take Coral’s headline: “Get £40 in Free Bets when you bet £20.” A punter reads the offer, deposits £20, places a £20 qualifying bet at minimum odds of 2.0 (1/1) and waits for settlement. The £40 in free bets is issued within seven days and expires seven days after issue.

The qualifying bet pays like any other bet: stake returned plus profit at the odds taken. At odds of 2.0 on a winning £20 bet, the return is £40 (£20 stake plus £20 profit). At odds of 2.0 on a losing bet, the stake is lost. The free bets are issued regardless of the qualifying bet’s outcome, but the £20 is at risk.

The free bets are stake-not-returned by default. Four £10 tokens, each usable on a market at or above minimum odds, with the stake not returned on a win. The punter’s expected value of each £10 free bet depends on the market chosen and the margin on that market. On a market with a thin margin — a 3% margin — a £10 free bet at odds of 4.0 is worth roughly £10 × (4.0 − 1) ÷ 4.0 × 0.97 = £7.28 in expected value. On a market with a thick margin — an 8% margin — the same bet is worth roughly £10 × 3 ÷ 4.0 × 0.92 = £6.90. The headline £40 is worth between £27.60 and £29.10 in expected value across the four tokens, depending on the markets the punter uses them on.

This is the working figure. A £40 headline is £27.60 to £29.10 in expected terms on a typical betting margin, before the punter’s own skill in selecting markets moves the number up or down. A punter who picks thin-margin markets and long odds gets closer to the top of the band; a punter who picks fat-margin markets at short odds gets closer to the bottom. The £40 headline is real money, but it is not £40 of real money.

The band widens under the 10x cap. The cap does not change the free-bet value — there is no wagering requirement on Coral’s free bets, so the cap is irrelevant here. But where an offer does carry a wagering requirement, the cap limits how much turnover the punter has to clear. A £10 bonus at 10x is £100 of qualifying bets; a £10 bonus at 50x would be £500 of qualifying bets, and the cap saves the punter from a structure that would have cost £400 more in qualifying turnover.

A worked calculation: clearing a £10 bonus at 5x with £5 stakes

Take a hypothetical welcome offer that awards a £10 bonus with a 5x wagering requirement at minimum odds of 1.5 (1/2) decimal 1.50, and a £5 stake per qualifying bet. The required turnover is £10 × 5 = £50. The number of bets at £5 each is £50 ÷ £5 = 10 bets.

Each bet at minimum odds of 1.5 has a margin of roughly 7-8%. The expected cost of the £50 turnover is £50 × 0.075 = £3.75 at a 7.5% margin, or up to £4 at an 8% margin. The punter is paying £3.75 to £4 to clear a £10 bonus, which gives an expected net of £6.00 to £6.25.

This is the favourable case. In the unfavourable case, a bookmaker’s terms count only winning bets toward the wagering requirement, which means a losing bet at minimum odds does not contribute to turnover. A punter whose qualifying bets win half the time and lose half the time at minimum odds would need roughly 20 bets at £5 to clear the same £50 of counted turnover, with an expected cost of £50 × 0.075 = £3.75 (only winning bets count, so the turnover figure is the same but the path is longer). A punter whose qualifying bets win a quarter of the time would need 40 bets at £5 to clear the same £50, doubling the expected cost in time and attention if not in money.

Under the 10x cap, the worst case is bounded. A £10 bonus at 10x is £100 of qualifying bets, ten to forty bets at £10 each. A punter choosing between a £10 bonus at 5x and a £50 bonus at 5x is choosing between £50 and £250 of qualifying bets, with the larger headline carrying five times the expected cost. The cap does not eliminate that scaling — a £50 bonus at 10x is £500 of qualifying bets, twice the cost of the £50 bonus at 5x — but it caps the multiplier at ten, and the cost scaling is bounded accordingly.

How to read a bookmaker’s promotion page

Five checks turn a headline into a working figure:

1. What is the trigger? Deposit, qualifying bet, or both. Read the minimum deposit, the minimum stake, the minimum odds.
2. What is the reward? Free bets, bonus, cash refund, stake-back. Note the headline figure and the token split.
3. What is the wagering requirement? The multiplier, the minimum odds for qualifying turnover, the games or markets that count.
4. What is the expiry? When the reward is issued, how long it is valid, what happens to unspent tokens.
5. What are the payment restrictions? Debit card only, no e-wallets, no credit cards, source-of-funds checks.

Run those five checks on any welcome offer at a British bookmaker, and the headline figure becomes a working figure. The arithmetic above then turns the working figure into expected value, and the expected value is what the punter is actually claiming.

Spread betting, the FCA and a separate licence

Spread betting is not fixed-odds betting. A financial spread bet is regulated by the Financial Conduct Authority under the Financial Services and Markets Act, not by the Gambling Commission. Spreadex is regulated by the FCA for spread betting and by the Gambling Commission for fixed-odds betting, and the published site states that spread betting losses can exceed the deposit.

The FCA regulation is a different regime: financial promotions rules, FCA-authorised status, and FCA dispute resolution. The Commission’s 10x rule does not apply to financial spread bets, because they are not Commission products. The mixed-product ban does not apply, because a financial spread bet is not a Commission product either. A punter reading a “free bet” promotion at a spread-betting operator should check whether the promotion is on the fixed-odds side (Commission rules apply) or the spread-betting side (FCA rules apply).

Spread betting losses can exceed the deposit. That sentence is the headline of every spread-betting advertisement for a reason — the punter’s liability on a spread bet is not capped at the stake, and the operator can call for further funds if the market moves against the position. A punter who wants the £60-in-free-bets welcome at Spreadex should take it on the fixed-odds side, where the Commission’s rules apply and the liability is capped at the stake.

How to check a bookmaker is licensed

The Commission’s public register can be searched by business name, trading name, domain or account number. Every brand on this page has an entry under its operating company: Platinum Gaming Limited for Unibet, PPB Counterparty Services Limited for Paddy Power, Copybet UK Limited for Copybet, Thistle Bet Limited for London Bet, Betway Limited for Betway, Blue Star Planet Limited for 10bet, BV Gaming Limited for BetVictor, Hollywoodbets International UK Limited for Hollywoodbets, LeoVegas Gaming PLC for BetUK, SBG Sports Limited for Sky Bet. The Commission account number sits beside each entry, and the licence categories — remote general betting standard (real events), in every case — name what the operator is licensed to take bets on.

A licensed operator uses .com as well as .co.uk. The domain proves nothing — a Curaçao-licensed operator can run a .co.uk domain, and a Commission-licensed operator can run a .com domain. The test is the Commission’s register, not the URL.

A single brand described as “the only licensed” operator is a misstatement. The register lists every licensed operator, and there are far more than ten. The ten in this comparison are a working shortlist for the welcome-offer question, not the licensed market.

The settlement picture: deposits, withdrawals and the identity check

Every licensed operator verifies name, address and date of birth before the first deposit or gamble. The verification is run against commercial databases and, where the database check is inconclusive, against photo ID and proof of address. The cost of the verification is the operator’s, not the punter’s; the time taken is typically minutes for a database hit and up to 24-48 hours for a manual document check.

The withdrawal side is governed by the operator’s own published terms. Most withdrawals to the original deposit method are processed within 24 hours; bank transfers may take longer. Withdrawal limits and processing times are operator-specific, not Commission-set, and the punter’s working assumption should be that withdrawals to a different method than the deposit take longer and carry additional checks.

Source-of-funds questions are normal under the money-laundering rules at higher spend. A punter whose deposits have reached a level that triggers a financial vulnerability check may be asked for payslips, bank statements or evidence of wealth. The question is not optional, and the operator’s response to an unsatisfactory answer is account restriction.

The age rule and the under-25 advertising rule

The minimum age for gambling in Great Britain is 18. A punter below 18 cannot open an account at a licensed operator, deposit, claim a free bet or place a bet. The rule is enforced at verification and at the point of any attempted transaction.

The CAP Code section 16 rule on advertising is separate from the age rule. It applies to marketing: no one who is or seems to be under 25 may be featured gambling or play a significant role in an advertisement, with an exception for marketing placed where a bet can be made directly. The rule concerns who may appear in the advertisement, not who may bet. A 19-year-old punter is permitted to bet; a 19-year-old model is not permitted to feature in a betting advertisement.

The “whistle-to-whistle” rule is an industry code, not law. Since 1 August 2019 betting advertisements are not shown on TV from five minutes before a live sporting event to five minutes after it, before the 9pm watershed (horse and greyhound racing excluded). The rule is operator-agreed and enforced through the BCAP Code; the Commission does not run it.

A note on the Premier League shirt-sponsorship withdrawal

The Premier League clubs’ withdrawal of gambling sponsorship from the front of matchday shirts from the 2026/27 season is voluntary, not law. Sleeves and hoardings remain. The change is a commercial decision by the clubs and the gambling operators, and the Commission has no role in it. A punter watching Premier League football in 2026+1 will see betting sponsors on sleeves and hoardings; the front-of-shirt is the only change.

The Premier League’s decision does not affect the operator’s licence, the welcome offer, or the 10x cap. It is a sponsorship change, not a regulatory change. A punter reading the change as a regulatory shift is reading it wrong.

How a promotion ages over the year

A welcome offer is one offer at one moment. Existing-customer promotions rotate weekly, sometimes daily. The published terms at the snapshot date are the terms in force at the snapshot date; a promotion that ran in March may not run in September, and a token-operated welcome plan may be replaced by a percentage-bonus welcome plan at the operator’s next refresh.

A punter choosing a bookmaker on the strength of one welcome offer is choosing on a moving target. The recurring value — the daily boosts, the acca insurance, the free-to-play games — is the part of the promotion shelf that pays back over a year, and that part is operator-specific in ways the welcome offer is not.

The honest read of a welcome offer, then, is as an introduction rather than a relationship. The £40 at Coral, the £40 at Unibet, the £30 at Sky Bet, the four £10 tokens at Betway and BetUK, the stake-back at Hollywoodbets, the 100% bonus at 10bet — each is a headline that turns into a working figure after the five checks above, and each is replaceable by the operator at any refresh. The relationship is the operator’s recurring promotions, the licence, and the platform. The headline is a hello.

Frequently asked questions

How do you use a promo code at a betting site?

A promo code, where a licensed British bookmaker offers one, is entered at the registration or deposit stage, often as part of an opt-in to the welcome offer. The code unlocks the offer the small print describes — the £40 in free bets, the four £10 tokens, the stake-back. The offer’s terms still apply: a minimum deposit, qualifying bet, minimum odds and an expiry window are unaffected by the code. The code is a switch; the small print is the contract.

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

Since 19 January 2026, the Gambling Commission has capped wagering requirements on bonuses at 10x. A £10 bonus can require no more than £100 of qualifying bets before withdrawal. The cap applies to the bonus alone or to the bonus-plus-deposit, depending on the operator’s terms, and it does not apply to a free bet with no wagering condition, because there is nothing to multiply.

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

A minimum odds line is the shortest price at which a qualifying bet counts toward the offer. A wagering requirement is the multiple of the bonus that must be turned over in qualifying bets before any winnings can be withdrawn. Both terms shape the cost of clearing the offer: minimum odds filter the punter toward higher-margin markets, and the wagering requirement sets the number of bets the punter has to place. The 10x cap is the ceiling on the second; the minimum odds is operator-set and varies across offers.

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

Stake-not-returned is the default in British online betting, and it is what makes a free bet a credit rather than a cash refund. A winning £10 free bet at odds of 4.0 returns £30 profit, not £40, because the £10 stake is the bookmaker’s contribution and is not part of the punter’s winnings. The mechanic is what gives a free bet its expected value rather than its headline value, and any operator that publishes stake-returned terms states that explicitly in the small print.

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

Since 19 January 2026, mixed-product promotions have been banned. An offer that requires gambling on two or more product types — betting, casino, bingo and lottery — cannot be marketed to British customers. A sports welcome offer that unlocks casino free spins is the textbook banned structure, and operators have separated sports and casino welcome offers to comply. A casino-only welcome offer is unaffected, and a sports-only welcome offer is unaffected; the rule concerns offers that cross the product boundary.

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

The Commission’s public register can be searched by business name, trading name, domain or account number. The register is the test: an operator’s entry on the register, with the right trading name and the right licence category, is proof that the operator holds a Commission licence. The register is searchable at no cost, and the entry names the operating company, the licence number, the licence categories and the trading names the licence covers. A punter reading a “we are licensed” claim on a bookmaker’s own site should verify the claim on the register before depositing.
