A promo code is a string of characters; the offer it unlocks is a contract. In Great Britain, the contract now sits inside a tighter frame than it did a year ago, and the frame is the only honest starting point for any decision about which welcome bonus or free bet to take. The rest of this page works outward from that frame — what the Commission has ruled on bonuses since 19 January 2026, how the four most common offer shapes actually work, and how the ten bookmakers the Gambling Commission has licensed for remote betting in this country treat the same kind of deal differently in their own terms.

The data was reviewed on 27 October 2026 against the Gambling Commission’s public register and the operators’ own terms pages; offer terms change often, so each figure is what the operator’s site said at that point and the reader should still check the live terms before staking.

What safer gambling tools already follow you into the offer

The choice between a £20 free bet at Sky Bet and four £10 free bets at Betway is not only a choice about money. Each operator runs the same national safeguards, and those safeguards shape the experience of claiming any welcome offer: how quickly you get verified, whether you can set a deposit limit before staking, and what happens if a punter decides to stop. Reading the offer without reading the safeguards is the single commonest mistake, because the deals were designed to be skimmed and the safeguards were not.

Identity verification is the gate every GB-licensed operator now closes before the first deposit or stake. Since 7 May 2019, name, address and date of birth have to be confirmed before a customer can deposit or gamble — and that includes staking a free bet or clearing a bonus. Kalooki Sportsbook’s site is explicit on this, and Midnite’s site lists the same check at the point of registration. There is no anonymous play at a licensed brand; the choice at the door is whether to be verified by a Commission-licensed operator or to play somewhere that does not check.

GAMSTOP is the second line that follows every welcome offer. It is the national multi-operator self-exclusion scheme and a mandatory licence condition for online operators since 31 March 2020. Kalooki Sportsbook’s homepage lists GAMSTOP membership alongside its licence; that listing is a fair proxy for the rest, because every GB-licensed online operator takes part. Self-exclusion runs for six months, one year, five years or five years with auto-renewal, and after the minimum period the exclusion stays in place for another seven years unless the customer asks GAMSTOP to remove it. A punter who has self-excluded cannot claim an offer, will not see marketing, and the operator cannot reopen the account during the period. The offer and the exclusion are not on the same screen because the offer page is built to convert; the exclusion lives behind a separate service for a reason.

Deposit limits are the third rail. Operators must offer a gross deposit limit on a fixed time frame, and the first changes took effect on 31 October 2025. A second phase has been postponed to 30 September 2026, and whether that second phase is now live is not settled. What is settled is that no Commission-licensed operator sets a ceiling the punter can ignore: a GB-licensed book runs on a limit the customer has chosen, not on a state-set cap, and the customer can lower that limit at any time and have any further deposit attempt refused during the cooling-off period. Several operators, including DAZN Bet, expose loss limits and wagering limits alongside the deposit limit as part of their safer-gambling tools.

A financial vulnerability check applies once a customer crosses £150 in net deposits in any rolling 30 days. Since 28 February 2025 the Commission has run that check at the £150 threshold, in line with licence condition 3.4.4, and the check is a public-record search — for bankruptcy or county court judgments — not an income check or a credit reference. It is the kind of check that prompts a request for source-of-funds documentation rather than a refusal at the door. A separate, heavier round of affordability assessments has been announced in a staged plan and carries no start date yet. The headline language of “affordability checks” should not be conflated with the £150 vulnerability check, which is already in force.

The three rules that govern how a welcome offer pays back sit one level further on.

How wagering requirements, free bets and bonus caps actually work

The single most useful sentence a punter can read before claiming any offer is also the shortest: a free bet usually does not return its stake, and a bonus usually must be turned over several times before any winnings turn into withdrawable cash. The Commission’s rules since 19 January 2026 have reshaped the second half of that sentence. The first half — the stake-is-not-returned convention — is still where most of the marketing language is doing its quietest work.

A wagering requirement is the multiple of a bonus that has to be staked before winnings become withdrawable. Under the Commission’s promotion rules in force since 19 January 2026, that multiple is capped at 10x: a £10 bonus can require at most £100 of qualifying bets before the winnings clear, and the rule is binding on every GB-licensed operator. It is a binding cap, not a guideline: a deal that asked for 20x in fifty bills would no longer pass the Commission’s licence conditions. The cap applies to wagering requirements on bonuses. Whether the same cap applies to a free bet that carries no wagering condition is not established; the Commission’s published position does not extend the cap to that case, and operators continue to issue free bets with no turnover attached. Mixed-product offers are now banned: any promotion that requires a customer to gamble on two or more product types — for example betting and casino, betting and bingo, betting and lottery — is out. A welcome bonus that paid a free bet in return for a £20 sports bet plus a spin on a slot is not a deal a GB-licensed operator can run.

A free bet is a token that replaces real money on a wager. When the wager wins, the book pays out the winnings at the stated odds; it does not pay out the stake of the free bet, because the stake was never the customer’s money. The contrast with a cash bet is the point: stake £10 on a 5.00 shot, win, the customer collects £50 in cash; stake a £10 free bet on a 5.00 shot, win, the customer collects £40 in cash — the £10 stake is gone. That is the mechanism behind every “free £30 in bets” headline. It is also why the headline and the realised value are not the same number.

A minimum price — expressed in fractional odds as evens, 1/1, 2.0, or in decimal odds — is the shortest price at which a qualifying bet has to be placed. A punter who backs a 4/6 shot at Sky Bet has not met the minimum price for the welcome offer; the bet does not qualify. Several operators attach the same kind of floor to the wagering bets that follow: the bonus has to be turned over at minimum odds, often 1/2 (1.50) or 2.0 (1/1), because the Commission’s cap on the multiple is meaningless if the multiple is being run at long odds that pay nothing. The minimum price is the bookmaker’s second line of defence, and it is one of the figures that varies most across the ten operators reviewed later in this page.

An expiry is the time window in which the bonus or free bet has to be used. Coral’s £40 in free bets expire 7 days after issue; Betway’s four £10 tokens carry a 7-day expiry; BetUK’s four £10 tokens are valid for 7 days and have to be placed on pre-set acca shapes. The window is short, the offer is front-loaded, and a punter who lets the timer run out has taken the loss without taking the upside.

The combination of these four — wagering multiple, stake-returned rule, minimum price, expiry — is what an offer actually costs. None of them appears in the marketing line. The arithmetic of clearing a bonus is the next thing the page has to do.

What clearing the bonus at Coral costs the punter

The clearest example in the current market is Coral’s sports welcome offer: place a sports bet of £20 at minimum odds of 2.0 (1/1), receive £40 in free bets within 7 days, expire 7 days after issue. The bonus is the £40 in free bets; the wagering requirement on the bonus is, in Coral’s published terms, none — these are free bets, not bonus credit that has to be turned over, and there is no wagering multiple to run. The cap on bonus wagering introduced on 19 January 2026 does not bind this offer because the offer is wagering-free.

What the offer does have is the rule on the free bet itself: Coral’s free bets return winnings only, not stake, and the value is fixed by what a free bet of the stated size wins on average at the price the punter chooses. Using the offer terms research sets out, a punter who takes the £40 in free bets at a representative football price of 5/1 (6.00 in decimal) and stakes the full balance in £10 tokens has four bets at the same price. The return on each winning token is £60 in winnings, and the realised value is the punter’s win-rate times the £60 per token. As a band, a punter whose tokens win at the market-typical rate will see roughly half of £240 — £60 per token times four tokens — as gross winnings, with the £40 stake absorbed by the operator and never returned. At longer prices the gross value rises and the chance of any token winning falls; at shorter prices the gross value falls and the chance rises. The realised value of a free bet is the punter’s edge on the price, and Coral’s offer moves that edge but does not eliminate it.

A punter who runs the bonus as a wagering turnover — that is, who treats the £40 as a bonus credit and tries to turn it over — is reading the wrong contract. Coral’s offer is a free bet, not a bonus; the £40 does not need to be turned over, the £40 is the offer. Where the calculation has force is on offers like 10bet’s 100% up to £50 bonus, where the bonus does carry a wagering multiple and the cost is the turnover the punter has to run before any of it clears.

For that shape, take a punter who claims a £10 bonus at a 5x wagering multiple — a typical figure before the 10x cap — and stakes at minimum odds of 1/2 (1.50): required turnover is £50, split across bets of, say, £5 each, which is ten qualifying bets at minimum price. Under the cap that is the floor: £10 × 10 = £100 is the most any operator can require, and most will not require that much. The realised cost of clearing the bonus is the margin the bookmaker keeps on the market the punter bets on; at a typical football 1X2 margin of 5%, the punter loses about £2.50 of the £50 turnover on average, with the £10 bonus wiping out roughly four-fifths of that loss. The shape of the calculation is the same whichever GB-licensed operator runs it, and that is what makes the cap meaningful: the same offer, with the same kind of punter behind it, now costs the operator less headroom than it did before 19 January 2026.

The headline is the number on the front of the offer. The realised cost is the figure on the next page of the operator’s terms. Both belong on the page the punter reads.

How the Gambling Commission shapes the offer a punter sees

The bookmaker is the seller; the Commission is the referee. The referee has been rewriting the rulebook on promotions since 19 January 2026, and the rules now in force are the reason a welcome offer in Great Britain in 2026 looks the way it does.

The Commission’s promotion rules cap wagering requirements on bonuses at 10x. That is the figure that defines the upper bound of the multiple any welcome bonus can carry, and it sits on top of the Licence Conditions and Codes of Practice that have governed marketing and social responsibility for years. The cap binds every GB-licensed remote operator, and any breach is an issue the Compliance team can act on through the licence. The Commission is a non-departmental public body sponsored by the Department for Culture, Media and Sport; the Gambling Act 2005 is the statute that sets up the licensing regime, and the Gambling (Licensing and Advertising) Act 2014 made the licence point-of-consumption: an operator whose remote facilities are used in Great Britain needs a Commission licence wherever it is based. A Curaçao, Maltese or Gibraltar licence is not a substitute, and a brand that runs only on a non-GB licence is providing gambling facilities in Great Britain without the licence the Act requires — an offence under section 33 of the 2005 Act, aimed at the operator.

The Commission’s public register is the test of whether a brand holds a licence. It can be searched by business name, trading name, domain or account number, and the operator’s own number on the register is the single piece of evidence a punter should expect to see. Unibet’s UK site is run by Platinum Gaming Limited, Gibraltar, under Commission account 45322; Betway runs under Betway Limited; Paddy Power under PPB Counterparty Services Limited; Copybet under Copybet UK Limited; Hollywoodbets under Hollywoodbets International UK Limited; BetUK under LeoVegas Gaming PLC; Sky Bet under SBG Sports Limited; 10bet under Blue Star Planet Limited; London Bet under Thistle Bet Limited; BetVictor under BV Gaming Limited. Ten licence holders, ten Commission accounts, all in the same remote general betting standard (real events) category. The Commission’s register is also where the punter confirms that a brand is licensed and where the punter can complain if a dispute cannot be resolved with the operator. A complaint about an unlicensed brand has no British route.

The promotion rules sit alongside a wider player-protection frame. Credit cards have been banned for gambling in Great Britain since 14 April 2020 — including credit-card-funded payments through an e-wallet — which is why every welcome offer in the next section qualifies on a debit card or an instant bank transfer. The minimum age is 18 and is verified at registration, alongside the identity check that runs before the first deposit. The financial vulnerability check at £150 net deposits in any rolling 30 days is the first stop on a heavier affordability regime the Commission has signalled but not dated. Advertising is not licensed by the Commission; it runs through the CAP Code (non-broadcast) and BCAP Code (broadcast), enforced by the ASA, and the CAP Code’s section 16 keeps marketing away from under-18s and stops anyone who is or seems to be under 25 from appearing in gambling advertising, with an exception for marketing placed where a bet can be made directly.

The duty that funds this regime is on the operator, not on the punter. General Betting Duty is 15% on gross profits, and from 1 April 2027 a remote betting rate of 25% applies within that duty; remote bets on UK horse racing, bets on self-service betting terminals in licensed premises, pool betting and in-person betting stay at 15%. Whether operators pass the duty on through odds is not established, and the punter pays no tax on betting winnings in Great Britain. A professional gambler should ask HMRC or an adviser; the rest of this page is general information, not tax advice.

What falls outside the regime is the question that decides the rest of this page. Offshore is its own column of the comparison and it is the column where the punter loses the protections the regime grants.

Offshore, and what an unlicensed site does not give the punter

A GB licence is the licence the Act requires. Without it, an operator is providing gambling facilities in Great Britain without authorisation, and the offence sits in section 33 of the 2005 Act. No offence aimed at the customer who merely bets on an unlicensed site was found; the framing the Commission has used is that the customer loses the protections the regime grants.

What the regime grants, on a welcome offer specifically, is the 10x cap on wagering requirements and the ban on mixed-product promotions. An offshore operator is not bound by the cap and is not bound by the ban. An offshore site also does not run GAMSTOP, does not run the £150 vulnerability check, does not require verification before the first deposit, and does not offer the Commission’s complaints route. Approved dispute resolution — the route that follows a failed first complaint — does not exist at an unlicensed brand. The punter’s recourse is whatever the operator’s own terms say, and whatever the operator’s own jurisdiction — Curaçao, Malta, an unregulated island — chooses to enforce.

Enforcement against unlicensed sites is disruption, not blocking. The Commission issues cease-and-desist notices, refers sites to search engines, and works with registrars, hosts and payment providers; the Commission has been given, or is about to receive, court-order DNS blocking powers. ISP blocking is not in operation as a settled regime, and the page should not claim that it is. The honest framing is the one the Commission uses: licensed means checks, limits, GAMSTOP, the bonus cap and the dispute route; unlicensed means none of those and possible loss of funds. Neither is “the safe choice” by default, because the licensed path takes identity verification and a verified check before the first deposit, and an unlicensed path takes none of those things.

A punter comparing one to the other is not comparing two versions of the same product. They are comparing a regulated offer inside a frame the regulator rewrote in 2026 to an offer the regulator does not reach.

How the offer shapes differ across the market

Every welcome offer in Great Britain is one of a small set of shapes, and the differences inside each shape are where the punter’s decision actually lives. The headline number is the easy read; the wagering multiple, the minimum price, the expiry and the stake-returned rule are the figures the next paragraph of the operator’s terms hides the real cost behind.

The most common shape is the free-bet welcome. Bet £X at minimum odds, receive £Y in free bets, expire in Z days. Sky Bet’s £30 in free bets after a £5 deposit and a 5p first bet at odds of 1/1 or greater is the lower end of the size of qualifying bet; Coral’s £40 in free bets after a £20 bet at 2.0 is a step further; Unibet’s £40 in free bets after a £20 bet at 2.0 mirrors Coral on the headline and runs on the same shape; Betway’s four £10 tokens after a £10 first bet at 2.0 sit at the same scale; BoyleSports’ £20 in free bets after a £10 bet is the smaller end. Free bets return winnings, not stake, and the value of the offer is the punter’s edge on the chosen price.

A second shape is the stake-back free bet, where the free bet fires only on a losing first wager. Hollywoodbets’ offer is the clean example: deposit £10 by card, place a first qualifying acca of 3+ legs at odds of 4/1 or greater, and if the acca loses the stake returns as a free bet of up to £30, valid for 7 days, one free bet per customer. The bet has to be settled within 7 days. The stake-back shape pays only on a loss, which makes the headline look generous and the realised value depend almost entirely on the punter’s first acca.

A third shape is the matched bonus, where the operator credits a percentage of the deposit as bonus that has to be turned over before withdrawing. 10bet’s 100% up to £50 is the kind of headline that signals this shape, with daily free bets and free spins alongside. A matched bonus carries a wagering multiple; under the 10x cap that means a £50 bonus can require at most £500 of qualifying bets, and the figure is usually lower. The minimum odds on the qualifying bets vary by operator, and the realised cost of the bonus is the margin the bookmaker keeps on the market the bonus is cleared through.

A fourth shape is the acca-insurance or loyalty shape, where a refund — usually a free bet — fires on a near-miss. BoyleSports’ Acca Insurance pays a refund as a free bet of up to £20 if one leg of an acca lets the punter down, with a £5 minimum stake, minimum odds of 1/2 on each leg, and the bet placed and settled on the same day. The Acca Loyalty shape pays a free bet when an acca of 5 or more settled legs lands at combined odds of 3/1 or greater, with the same 7-day expiry. These shapes do not gate the welcome offer; they run alongside it, and they are how operators keep the regular customer inside the marketing loop after the welcome bonus has cleared.

The fifth shape — the one the Commission’s rules have just changed — is the mixed-product promotion. A welcome offer that paid a free bet for a £20 sports bet plus a free spin on a slot is not a deal a GB-licensed operator can run after 19 January 2026. The cap on bonus wagering and the ban on mixed-product promotions are the two most concrete changes the Commission has made to the offer set, and the change is visible in the marketing the operators ran in the year before.

What the operators do with the same four shapes — what they pay, what they require, and what they ask the punter to read — is what the comparison table in the next section carries. What the operators do not tell the punter, even when their terms do, is the realised cost of the offer they are signing for. The cost is the margin the operator keeps on the market the offer is cleared through; the offer is the price the punter pays to enter that market.

Comparing the ten GB-licensed bookmakers

The ten operators in this comparison all hold a Gambling Commission remote licence for general betting standard (real events). The order in the table reflects the licence-led register rather than any ranking by offer size: a Commission account on the public register is the floor, not the ceiling.

A licence number on the public register is the floor the punter needs. Everything in the third column is the operator’s own description of its offer or product set, lifted from the live terms or app listing at the snapshot date. No licence number on its own is a recommendation; no offer on its own is a verdict; no column says which offer is the best value at any given stake.

What each operator does differently

A licence confirms the operator is allowed to take the bet. It does not say anything about how the operator runs the same kind of deal differently. The next ten short reads are not reviews; they are the differences a punter comparing the operators should see, written so a punter can decide which operator’s shape fits.

Unibet

Unibet’s UK site has run since 1999 under Platinum Gaming Limited, and the welcome offer mirrors Coral’s headline almost exactly: £40 in free bets for a £20 qualifying bet at minimum odds of 2.0, free bets expiring within 7 days. The shape is a free-bet welcome, debit-card or instant-bank-transfer only. The platform is heavier than the welcome offer: Bet Builder, daily Uniboosts, live streaming through Unibet TV, in-play betting, Best Odds Guaranteed on horse racing, and Cash Out across thousands of markets. The free bets do not return stake, the qualifying bet has to clear at 2.0 or longer, and the offer runs only for new GB customers. The verdict for a punter weighing Unibet against Coral is that the two sites are advertising the same deal; the difference is what the platform does when the welcome bonus has cleared.

Paddy Power

Paddy Power’s licence is held by PPB Counterparty Services Limited; the app exposes 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. The promotional cycle that sits behind those features is one of the busiest in the British market, and the welcome offer sits inside it as one of several shapes a new customer can land on. A punter who wants the broadest in-play menu and the most aggressive promotions will find more at Paddy Power than at most of the other nine operators in this comparison. The trade-off is the same one every multi-product operator runs: more surface area, more offers, more to read.

Copybet

Copybet’s licence is held by Copybet UK Limited, and the platform’s defining mechanic is its acca-led product. The Acca Booster pays up to 100% cash bonus on accas of at least 3 selections, and a Daily Profit Boost of up to 15% runs alongside. The platform is built for the punter who backs accumulators regularly, and the booster is the kind of loyalty shape that compounds for high-volume acca backers rather than the casual once-a-week punter. A punter who places one football acca a week will not see the same realised value as a punter who runs a dozen a weekend, and Copybet’s welcome offer is the place the casual punter decides whether to commit.

London Bet

London Bet is published by Thistle Bet Limited, and the operator’s app carries a 17+ age rating on the App Store. The product set is the smaller end of the ten in this comparison; the licence is the same shape the rest of the table carries, and London Bet has the same obligations on identity verification, GAMSTOP and the safer-gambling tools. The decision to take the welcome offer at London Bet is rarely about a feature the other nine do not have; it is about a brand a punter has heard of or one they have not. A punter who likes the smaller site for any reason should still take it through the same licence check the rest do, and the offer’s worth is the offer’s worth whichever licence holder runs it.

Betway

Betway runs under Betway Limited, and the welcome offer is £40 in four £10 free bet tokens, credited on settlement of a first bet of at least £10 at minimum odds of 2.0, 7-day expiry, debit card deposits only. The platform is broad: in-play markets across football, tennis, horse racing and the US sports; Bet Builder; a casino tab the Commission’s rules have just made separate from any welcome offer. The verdict is that Betway is the kind of operator a punter picks for the platform rather than for the welcome offer; the £40 in free bets is close to the standard shape, and the seven-day expiry is short.

10bet

10bet runs under Blue Star Planet Limited, and the welcome headline is a 100% up to £50 betting bonus for UK sign-ups, with daily free bets and free spins alongside. The headline is the matched-bonus shape the Commission’s 10x cap now governs; the cap on bonus wagering is binding on the offer, and the realised cost is the margin on the market the bonus is cleared through. The free spins sit on the casino side of the licence and are now governed by the mixed-product ban if they are tied to the betting offer. A punter reading 10bet’s terms should expect the matched bonus to carry a turnover requirement and a minimum price on the qualifying bets.

BetVictor

BetVictor runs under BV Gaming Limited, and the platform’s distinguishing feature is the depth of its pricing: regular price boosts, acca offers and free bets on selected events, with the welcome offer shown in the app and governed by customer terms and conditions. BetVictor’s offer set is closer to a sportsbook-led product than a casino-led one, and the welcome offer is the kind of free-bet shape most of the other operators in this comparison carry. A punter reading the BetVictor terms should still see the same minimum-price, expiry and stake-returned structure; the brand’s edge is in the price the platform offers rather than in the shape of the welcome bonus.

Hollywoodbets

Hollywoodbets runs under Hollywoodbets International UK Limited, and the welcome offer is the stake-back shape: deposit £10 or more by card, place a first qualifying acca of 3+ legs at odds of 4/1 or greater, settle within 7 days, and the stake returns as a free bet of up to £30 if the acca loses. One free bet per customer. The offer pays only on a loss, which is the reason the £30 figure looks generous next to a £30 free bet that pays only on a win. The punter’s edge is the chance their first acca actually wins, in which case the offer pays nothing; the offer pays when the punter’s first acca loses, in which case the stake returns as a free bet the punter has to clear.

BetUK

BetUK runs under LeoVegas Gaming PLC, and the welcome offer is four £10 free bets on deposit of £10+ and a sports bet within 7 days of registering: two football accumulators of 4+ selections and two multiples of 2+. Opt-in required, valid for 7 days. The offer gates the free bets on pre-set bet shapes — a punter who backs a single loses the right to two of the four free bets — which is the most concrete constraint on a welcome offer in this comparison. The verdict for a punter weighing BetUK is that the offer pays more for the punter who already backs accas and multiples than for the punter who backs singles; the constraint is the trade for the headline.

Sky Bet

Sky Bet runs under SBG Sports Limited, and the welcome offer is the lowest-friction shape in the market: £30 in free bets as three £10 tokens on deposit of at least £5 and a first single or each-way bet of at least 5p at odds of 1/1 or greater. The qualifying bet is a token — the punter can place 5p — and the qualifying odds are 1/1 (2.0). The seven-day expiry is the same shape most of the other operators carry; the deposit threshold is the loosest in this comparison. A punter who wants the smallest commitment to qualify for a free-bet welcome will find the lowest door at Sky Bet; a punter who wants the most free-bet value will find a higher headline elsewhere and pay for it with a larger qualifying bet.

The mechanic the operators share, and the choice each leaves the punter

The ten operators carry the same four shapes the previous section described; the differences are in the size of the headline and the constraint that sits on top of it. The mechanic the punter needs to read is not on the offer page. It is in the operator’s terms, in the next paragraph, in the figures the headline does not print.

A free-bet welcome offer at minimum odds of 2.0 with a 7-day expiry is the default. The realised value is the punter’s edge on the chosen price, and the marketing word is “free” — a word that pays the winnings only. A stake-back free bet on a losing acca is the second shape, and it pays the punter for a loss rather than a win. A matched bonus up to £50 is the third shape, governed by the 10x cap on bonus wagering and the ban on mixed-product promotions. An acca insurance or loyalty shape is the fourth, sitting alongside the welcome offer rather than replacing it. The mixed-product shape is the one the Commission’s rules now ban and the one that used to be the most aggressive form of the welcome bonus.

The choice each operator leaves the punter is the same one the regulator has been making for them: read the next paragraph of the terms before staking, decide whether the headline number is worth the constraint that comes with it, and check the licence on the Commission’s public register before claiming. The punter who does those three things has done what the marketing page is designed to make unnecessary.

How to read a UK bookmaker’s welcome offer in 2026

The order a punter works through an offer is the order this page has taken to lay it out. Reading an offer without reading the terms is the most common reason a punter ends up worse off than the marketing suggested.

The first check is the licence. The Commission’s public register is searchable by business name, trading name, domain or account number, and the punter should expect to see the operator’s name and account number on the register before staking. Unibet’s site lists 45322; Betway lists 39372; Sky Bet lists 67370. The licence is the only proof the operator is allowed to take the bet in Great Britain, and the punter’s complaints route runs through the Commission if the operator cannot resolve a dispute.

The second check is the offer shape. A free-bet welcome, a stake-back free bet, a matched bonus, or an acca insurance shape are the four shapes in the British market in 2026. The headline number, the minimum price, the expiry and the stake-returned rule are the four figures to read on the offer page itself.

The third check is the wagering requirement. Under the Commission’s rules since 19 January 2026, no GB-licensed operator can require a punter to turn a bonus over more than 10 times before withdrawing winnings; a £10 bonus can require at most £100 of qualifying bets. Mixed-product promotions — an offer that ties betting to casino, bingo or lottery — are banned. A welcome offer that asks the punter to back a football match to claim a free spin at the slots is not a deal a GB-licensed operator can run.

The fourth check is the minimum price. Most welcome offers qualify on a minimum price of 1/2 (1.50) or 2.0 (1/1), and several operators apply the same floor to the wagering bets that follow the welcome bonus. A punter who backs a shorter price does not qualify; the bet does not count.

The fifth check is the expiry. Coral’s £40 in free bets expire 7 days after issue; Betway’s four £10 tokens carry a 7-day expiry; BetUK’s four £10 tokens are valid for 7 days. A punter who lets the timer run out has taken the loss without taking the upside.

The sixth check is the safer-gambling tools. GAMSTOP, identity verification, deposit limits, the £150 vulnerability check, and the financial risk assessments the Commission has signalled are the framework inside which every welcome offer runs. The punter who reads the offer page and skips the safer-gambling tools is reading the offer the operator wants read; the offer that is actually on the table includes the framework.

The seven-check is a number a punter who wants to estimate the realised value of a free-bet welcome can run. A £30 free bet on a 5.00 shot pays £150 in gross winnings if it wins; with a 20% chance of winning at that price, the realised value is £30, which is exactly the headline. At a 6.00 shot the realised value rises to £36; at a 4.00 shot it falls to £22. The realised value is not the headline, and a punter who reads the offer as if it were is reading the marketing.

What sits outside the welcome bonus, and why it still costs the punter

The welcome bonus is the offer a punter sees first, and the offer the marketing budget pays to display. It is rarely the only offer on the table; the regular offers — acca insurance, price boosts, daily free bets, loyalty boosts — are the ones the punter sees after the welcome bonus has cleared, and they are the ones the operator uses to keep the punter betting on the same site.

A price boost raises the price the operator offers on a selected market for a limited window. Coral’s Odds Booster covers hundreds of markets, and Kwiff’s Supercharge can lift the price on a bet from 2/1 to 20/1 on a single bet or a multi. The price boost is real and verifiable on the bet slip; it is not the same as a free bet, because the punter’s stake is real money and the winnings are real money. The realised value of a price boost is the difference between the boosted price and the market price, and a price boost at long odds on a market the punter was going to back anyway is the closest thing to a free upgrade the offer set has.

An acca insurance refunds the stake of an accumulator as a free bet if one leg lets the down the punter. BoyleSports’ Acca Insurance refunds up to £20 as a free bet, with a £5 minimum stake and minimum odds of 1/2 per leg, and the bet has to be placed and settled on the same day. The refund is a free bet, which means the refund’s stake is not returned if the free bet wins. The realised value of the insurance is the chance the punter’s acca would have lost by exactly one leg — the rarer the loss-by-one event, the lower the realised value.

A daily free bet or loyalty boost is the smallest regular offer on most platforms, and it is the offer the punter sees most often. Coral’s free daily Reward Shaker, Paddy Power’s regular free-to-play games, William Hill’s Football Acca Boost — which pays a cash boost from 3% on a double to 200% on 20 or more legs, with a maximum boost of £10,000 per online bet and runs until 30 May 2027 — are the regular offers a punter sees once they have signed up. The realised value of these offers is the same calculation as the welcome offer, run at a smaller scale.

A betting exchange sits in the same regulatory frame but under a different licence — the remote betting intermediary licence — and is governed by rates and rules specific to the exchange. The punter who uses an exchange lays as well as backs, and the realised value of an offer on an exchange is the commission the exchange charges rather than the margin the bookmaker keeps. This page’s ten operators are bookmakers, not exchanges, and the difference is the difference between taking a price and making a price.

What sits outside every offer on this page is the cost of the offer to the punter who does not claim it. A punter who skips the welcome bonus and bets at the unboosted margin has paid the operator’s full margin on every bet and has kept every winning pound. A punter who claims the welcome bonus has paid the operator’s full margin on the qualifying bet, paid it again on the wagering turnover where the bonus has to be cleared, and paid it once more on the free bets where the stake is not returned. The welcome bonus is a discount on the cost of those margins, and the realised value of the discount is what the headline says — at best.

How the ten operators expose the same product differently

The next section is the one that turns the differences between the operators into the decision a punter has to make. Each operator exposes a version of the same product — a sportsbook with a welcome offer, in-play markets, a bet builder, a price-boost programme — and the differences are in the surface area each operator puts on top.

The welcome offer

The ten operators split cleanly across the four shapes. Coral, Unibet, Sky Bet, Betway, BoyleSports and BetVictor run the free-bet welcome, with the headline ranging from £20 in free bets at BoyleSports to £40 at Coral and Unibet. Hollywoodbets runs the stake-back free bet, where the offer pays only on a losing first acca. 10bet runs the matched bonus, with the 100% up to £50 headline. BetUK runs a free-bet welcome gated on pre-set bet shapes — accas of 4+ selections and multiples of 2+ — which is the most concrete constraint in the comparison. Paddy Power and Copybet run platform-led welcome offers where the welcome bonus is one of several promotions; the platform rather than the offer is the brand’s edge.

The bet builder

Bet Builder is the same product on every platform that runs it: a feature that lets the punter combine markets from one event into a single bet. The differences are in the surface each operator puts on top. Bet365 runs Bet Builder+ (combining markets from one event, available pre-match and in-play), Super Boosts, Winnings Boosts on Bet Builders and selected singles, and daily Bet Boosts. Kwiff runs Bet Builder and Bet Builder+ (combining Bet Builder bets from different games) and a guaranteed weekend acca boost. Paddy Power runs Bet Builder+, Popular Bet Builders and Super Sub, where the bet rolls over to the replacement if a selected player is substituted. DAZN Bet runs Bet Builder and daily bet boosts. Unibet runs Bet Builder alongside daily Uniboosts and Cash Out on thousands of markets.

The in-play product

In-play betting is offered by every operator in this comparison. The differences are in the markets the operator runs and the controls the operator puts on the live product. Star Sports runs pre-event and in-play markets on football, horse racing, golf and US sports; Spreadex runs the same and offers Acca Boosts of 5% to 100% on football accumulators of three or more selections. DAZN Bet runs Cash Out on its in-play product but explicitly does not guarantee Cash Out availability; bets stand if Cash Out is unavailable.

The loyalty offer

The loyalty offer is where the platform rather than the offer is the brand’s edge. William Hill’s Football Acca Boost pays a cash boost from 3% on a double to 200% on 20 or more legs, with a maximum boost of £10,000 per online bet, and runs until 30 May 2027. BoyleSports’ Acca Loyalty pays a free bet on accas of 5 or more settled legs at combined odds of 3/1 or greater, with a £5 minimum stake and a 7-day free-bet expiry. Copybet’s Daily Profit Boost pays up to 15%. Coral’s Reward Shaker is a free daily prize, and the Odds Booster runs on hundreds of markets. The loyalty offer is the offer the punter sees after the welcome bonus has cleared, and it is the offer that decides which platform a punter stays on.

The safer-gambling tools

Every operator in this comparison runs the same safer-gambling tools: identity verification before the first deposit, GAMSTOP, deposit limits, the £150 vulnerability check, and access to GamCare and the National Gambling Helpline. The differences are in how each operator exposes the tools. DAZN Bet exposes deposit limits, loss limits and wagering limits as in-account settings. Hollywoodbets, Unibet and the rest expose deposit limits at registration or in the safer-gambling section. The Commission’s framework is the floor; the operator’s exposure is the surface.

The payment terms

Credit cards are banned for gambling in Great Britain, including credit-card-funded payments through an e-wallet. Every welcome offer in this comparison qualifies on a debit card or an instant bank transfer. Coral’s site lists Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly among its payment options. Betway’s offer is debit-card-deposits only. The punter who funds the account through an e-wallet funded by a credit card has not qualified for the offer.

The reader the page has not written for

The page has written for the punter who reads the operator’s terms before staking, who checks the licence on the Commission’s public register, and who decides whether the headline number is worth the constraint that comes with it. The page has not written for the punter who looks for a sure thing — no such thing exists on a sportsbook — or for the punter who treats a welcome bonus as a substitute for the cost of the margin. A welcome bonus is a discount on the cost of the margin; the cost is the margin.

The page has also not written for the punter who would back an unlicensed site to save the identity check. The identity check is the price of the licence; the licence is the price of the dispute route, the GAMSTOP coverage, the bonus cap and the safer-gambling tools. An unlicensed site does none of those things and the punter who chooses it has chosen to do without them. The Commission’s enforcement is disruption, not blocking; the punter who reads the regime as protection is reading it right, and the punter who reads it as a marketing line is reading it wrong.

A welcome offer at a GB-licensed bookmaker in 2026 is the offer a punter sees because the operator has spent a marketing budget on the page the punter is reading. The realised value of the offer is the punter’s edge on the chosen price, the constraint the operator has placed on the bonus, and the margin the operator keeps on the market the offer is cleared through. The offer is the page; the cost is the next paragraph; the licence is the floor.

What a punter leaves on the table

A punter who reads only the marketing page leaves three things on the table. The first is the wagering multiple: under the 10x ceiling the offer can carry, the punter who reads the multiple can decide whether the bonus is worth the turnover. The second is the minimum price: a bet at 1/2 does not qualify most offers, and the punter who reads the minimum price can decide whether the offer fits the markets they actually back. The third is the expiry: a 7-day window is short, and the punter who reads the expiry can decide whether the offer fits the calendar they actually bet on.

A punter who reads the next paragraph of the terms also leaves less money on the table, because the next paragraph is where the offer’s cost lives. A free-bet welcome at minimum odds of 2.0 with a 7-day expiry is the headline; the wagering multiple, the minimum price, the expiry and the stake-returned rule are the cost. A welcome bonus that looks generous in the headline is rarely generous in the realised value, and the realised value is what the punter pays.

A punter who reads the licence on the Commission’s public register also leaves less money on the table, because the licence is the only proof the operator is allowed to take the bet in Great Britain. The licence is the floor; the offer is the ceiling; the realised value is what the punter keeps. The punter who treats the licence as a marketing line is treating the offer as a marketing line, and the offer is built to be skimmed.

What the page does not cover

The page has not covered spread betting that is not a financial product — a different licence and a different duty — and has not covered the betting exchange’s rates and rules. The page has not covered the punter’s tax position beyond the general information that no tax is paid on betting winnings in Great Britain; a professional gambler should ask HMRC or an adviser. The page has not covered the operator-by-operator safer-gambling tools in the depth the Commission’s framework exposes them; DAZN Bet’s loss limit wagering limit is one example, and the rest of the operators run the same tools with different surfaces. The page has not covered the marketing and affiliate side of the offer — an affiliate can carry an offer the operator is responsible for — and has not covered the Commission’s enforcement record against unlicensed operators in the depth a reader would need to assess any single case.

The page has covered what a welcome offer at a GB-licensed bookmaker in 2026 is, what it costs, how the Commission has reshaped the offer set since 19 January 2026, and how the ten operators in this comparison run the same kind of deal differently. The rest of the page is the questions a punter is most likely to ask.

Frequently asked questions about bookmaker promo codes in Great Britain

How does a punter use a promo code at a betting site?

A promo code is a string of characters entered at registration or at the deposit step to unlock a welcome offer or a free bet; the offer the code unlocks is governed by the operator’s terms, not by the code itself, and the punter should read the terms before staking because the headline number is rarely the realised value. A credit-card deposit will not qualify any welcome offer in Great Britain, and the offer is paid only after identity verification has been completed.

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

Under the Gambling Commission’s promotion rules in force since 19 January 2026, no GB-licensed operator can require a punter to turn a bonus over more than 10 times before winnings become withdrawable, and any offer that asks the punter to gamble on two or more product types is banned. A £10 bonus at 50x wagering would need £500 of qualifying bets; under the cap no more than £100, and most operators ask for less.

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

A wagering requirement is the multiple of a bonus that has to be staked before winnings become withdrawable; a minimum odds figure is the shortest price at which a qualifying bet can be placed. A punter who backs a 4/6 shot on a welcome offer that requires minimum odds of 2.0 has not qualified the bet, and a punter who backs at 2.0 on an offer with a 5x wagering requirement has to stake five times the bonus before any winnings turn into cash.

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

A free bet is a token that replaces real money on a wager, and when the wager wins the book pays out the winnings at the stated odds rather than returning the stake, because the stake was never the customer’s money in the first place. Stake £10 cash on a 5.00 shot and the customer collects £50 in cash; stake a £10 free bet on the same shot and the customer collects £40 in cash, with the £10 stake absorbed by the operator.

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

Mixed-product promotions are banned under the Commission’s rules in force since 19 January 2026, and any offer that requires gambling on two or more product types — for example betting and casino, betting and bingo, or betting and lottery — is now prohibited. The Commission’s licence conditions do not allow such a structure.

How can a punter check 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, and the operator’s own account number on the register is the single piece of evidence a punter should expect to see. The register also confirms the licence category — for the operators in this comparison, remote general betting standard (real events) — and is the route the punter can use to complain if a dispute cannot be resolved with the operator.
