A promo code is a small thing on the page — a string of letters the operator prints in a corner of an advert, a banner, a footnote. What it actually unlocks sits behind it: a welcome bonus, a free bet, a refund on a losing accumulator, a price boost on a Saturday accumulator. The code itself does nothing. The terms behind it decide whether the offer is generous, ordinary or poor. And since 19 January 2026 the terms themselves sit inside a tighter frame: the Gambling Commission caps wagering requirements on bonuses at 10x and forbids offers that mix betting with another product. A £10 bonus at 50x turnover, which was a routine shape of promotion in 2024, now requires £500 of qualifying bets and is unlawful; under the cap the same bonus takes the customer to £100. That is the single biggest change to UK betting promotions in a decade, and it is the lens through which every welcome offer on this page is read.

What follows is a guide to the promotions that GB-licensed bookmakers are running now, what each costs the customer in turnover, in minimum odds, in expiry windows and in lost stake, and which of them suit which kind of punter. There is no shortcut through a promo code: the offers in this market work the same way in principle — money in, then a stake at a minimum price, then a bonus or free bet — and they vary in what they cost.

The Promotion Landscape in Great Britain

What a betting promotion is, and what the Commission now allows

A betting promotion is an offer by a bookmaker that credits a customer with something — a bonus, a free bet, a refund, enhanced odds, a price boost — in exchange for a qualifying action. The qualifying action is almost always a deposit followed by a bet at a stated minimum price, sometimes several bets, sometimes a stake split across an accumulator with a minimum number of legs. The credited thing is the promotion itself. Everything else — the amount, the wagering multiple, the expiry window, the rules on whether the stake comes back — is a condition.

The Gambling Commission’s promotion rules, in force since 19 January 2026, change what conditions are legal. Two conditions matter most. First, the wagering requirement on a bonus is capped at 10x. A wagering requirement is the multiple of the bonus amount the customer must stake in qualifying bets before the bonus and any winnings from it become withdrawable: a £20 bonus with a 5x requirement means £100 of qualifying bets; a £20 bonus with a 10x requirement means £200; a £20 bonus with a 50x requirement means £1,000, and that is the kind of figure the rule now outlaws. Second, an offer that requires a customer to gamble on two or more product types — for instance a free bet on football bundled with free spins on a slot, or a sports bonus tied to a casino wager — is banned outright. What stays legal is single-product promotions: a sports free bet, an acca boost, a refund on a losing sports accumulator. What does not is anything that drags the customer into casino, bingo, lottery in order to unlock a sports credit.

The cap does not cover everything. Whether a 10x wagering cap applies to free bets whose only condition is to use them within an expiry window — the common “free bet, no rollover” shape — is not established. Neither is any cap on the absolute money value of a bonus. A bookmaker may still credit £100 in free bets to a new customer, and may still impose a 7-day expiry, and may still restrict the free bet to minimum odds of 1/2 (1.50) or greater. What it may not do is attach a 50x turnover to a £10 bonus, or require the customer to play £20 of casino to unlock £20 of sports credit.

Why the offer matters less than the turnover behind it

The marketing on a welcome offer is the number it gives the customer: £40 in free bets, £60 in free bets, stake back up to £30, a £20 free bet on a £10 stake. The number is the headline. The cost is the line below it. Three figures matter, and a sharp reader reads them before the headline:

• Wagering requirement. The multiple of the bonus the customer must stake in qualifying bets before the bonus and any associated winnings can be withdrawn. Under the 10x cap, a £20 bonus requires at most £200 of bets before the money is the customer’s. Some offers carry no wagering requirement at all: the bonus is credited, used once or more, and any winnings are withdrawable. That shape is rarer and more valuable per pound credited.
• Minimum odds. The minimum price at which the qualifying bet, or the bet placed with the free bet, must be placed. Minimum odds of 2.0 (1/1) on the qualifying bet are routine; minimum odds of 1.5 (1/2) on the bet placed with the free bet are routine. The minimum odds gate matters because it forces the customer into markets with a wider margin, or into accas with more legs. Either path increases the expected cost of clearing the promotion.
• Expiry. How long the customer has to use the free bet or clear the bonus. A 7-day expiry is the norm at GB bookmakers. A 30-day expiry is generous by current standards. Expiry is the one condition a customer can do nothing about: the clock runs from credit, and an unused free bet is a free bet the customer paid for with their qualifying stake.

A fourth figure, present on some offers and absent on others, is the stake return. A free bet whose stake is returned with a winning bet is worth more than a free bet whose stake is not. The standard GB shape is the latter: place a £10 free bet at 5.0, win, and the customer receives £40 (£10 × 4.0 profit); the £10 stake is gone. A bookmaker that returns the free-bet stake along with the win credits £50. The shape is rarer because it costs the bookmaker more, and the Commission has not intervened in it.

The bookmaker’s margin, sitting under the offer

Every odds figure on this page carries a margin inside it. A margin is the share of every pound staked that the bookmaker keeps on a market across all outcomes: a 5% margin means 95p returned to customers on average for every £1 staked. The promotion never mentions the margin, but the minimum-odds gate on a welcome offer is a margin question in disguise. A bookmaker that sets the minimum price for the qualifying bet at 2.0 (1/1) is asking the customer to bet into markets whose margins are wider than the 1.20 to 1.50 range that football favourites typically run at. A bookmaker that asks for a 5-leg accumulator with combined odds of 4/1 or greater is asking for a bet whose compounded margin is even smaller than the per-leg margin — but the chance of winning is lower, and the customer is paying for the bonus with the chance of a win, not with a known cost.

This is the layer the marketing does not talk about, and the layer that decides whether a welcome offer is worth taking. An offer with no wagering requirement, no minimum odds on the free bet and a 30-day expiry is good value. An offer with a 10x wagering cap, a 2.0 minimum on the qualifying bet and a 7-day expiry is ordinary. An offer with a 10x cap, minimum odds of 1.5 on the free bet and a 7-day expiry, and where the free-bet stake is not returned, costs the customer more than the headline number implies. The arithmetic of that cost runs through a separate section below.

How the Welcome Offers Here Compare on Their Terms

The ten bookmakers covered later on this page each run a welcome offer of some shape. The table below is not a ranking — it is a snapshot of the headline promotion each operator currently states, the licence holder that runs it, and what each operator’s own terms say about the offer’s key conditions. The wagering requirement column reflects what the operator states: where the offer is a free bet with no rollover, that is stated plainly; where the offer carries turnover, the multiple is stated as the operator publishes it.

Reading a welcome offer well means treating the headline as a starting figure and the terms as the price. Hollywoodbets’ “stake back up to £30” credits a free bet on a losing accumulator; the customer loses the qualifying stake by definition (the bet has lost), so the headline is what the operator gives back, not what the customer ends with. Bet600’s “£10 free bet after five qualifying bets” requires the customer to stake £50 first at minimum odds of 2.0 before receiving any credit; the customer has paid for the free bet with the qualifying stake, and the value of the free bet is what matters. Smarkets’ £60 in free bets for a £20 qualifying bet at minimum odds of 3.0 carries the highest minimum price of the set, which means the customer is betting into markets where the bookmaker’s margin is wider and the chance of the qualifying bet winning is lower.

The Commission cap at 10x applies only to offers that carry a wagering requirement. Most welcome offers in this market are “free bet, no rollover”, in which case the customer takes the free bet once or more during the expiry window and any winnings are theirs. The cap bites hardest on the smaller reload bonuses, deposit bonuses and casino-linked offers that GB-licensed sites used to attach as a second hook. The single-product rule bites on anything that crossed over from sports into casino, bingo or lottery. The two together have simplified what GB-licensed sites can put on the page.

Legality and the British Frame

The Gambling Commission and the licence to take bets in Great Britain

The regulator is the Gambling Commission, a non-departmental public body sponsored by the Department for Culture, Media and Sport. It licenses the whole commercial market under the Gambling Act 2005, which covers England, Scotland and Wales. Northern Ireland sits outside the 2005 Act and runs its own older law; a “GB licence” or “GB-licensed” is correct terminology, and a Commission licence does not regulate Northern Ireland. Since the Gambling (Licensing and Advertising) Act 2014 an operator whose remote facilities are used in Great Britain needs a Commission licence wherever it is based, under sections 33 and 36 of the 2005 Act as amended. A Curaçao, Maltese or Gibraltar licence is not a substitute at the British point of consumption.

The Commission’s public register is the test. It is searchable by business name, trading name, domain or account number. Every brand on this page appears there, against a company whose legal title is the licence holder. The register is the only reliable way to verify a licence; licensed operators use .com as well as .co.uk, so the domain proves nothing. No brand in the British market is “the only” licensed one — the register lists hundreds of account holders, and a feature in a betting guide is not a licence.

Licence categories are specific. A remote general betting standard (real events) licence covers fixed-odds and pool betting on real sporting events; this is the category almost every brand on this page holds. A remote general betting standard (virtual events) licence covers computer-generated events; that is a separate permission. A remote betting intermediary licence covers betting exchanges; Smarkets holds one. A remote pool betting licence covers pool operators; the Tote holds one. These are different legal permissions with different rules on what may be offered and how. A brand licensed only for virtual events may not, in general, offer bets on Premier League football.

Identity, age and the financial-vulnerability check

The minimum age is 18. Name, address and date of birth are verified before the customer can deposit or gamble at a GB-licensed site — since 7 May 2019, including when the credit is a free bet or bonus. The rule is the same for e-wallets and bank-based payments: verification happens before the first stake, not at withdrawal. This is the rule that makes anonymous play impossible at a licensed site, and the rule that lets the operator apply affordability and vulnerability checks on the customer’s own data.

A financial vulnerability check, under Licence Conditions and Codes of Practice (LCCP) condition 3.4.4 in force since 30 August 2024, applies when deposits minus withdrawals exceed £150 in a rolling 30 days — a threshold live since 28 February 2025. The check is a public-record search (bankruptcy, county court judgments, similar); it is not an income check and it is not a credit reference check. Financial risk assessments — sometimes called affordability checks in the press — are announced in a staged plan (a Commission note of 7 July 2026 sets out the timetable) but have no start date, and the proper phrasing is announced, staged, no start date. A licensed operator is required to act on what the checks turn up, and is required to interact with the customer where interaction is appropriate; it is not a test the customer passes or fails.

What may be bet on, and what may not

There is no statutory list of permitted bets. The framework is licence category plus the LCCP plus the operator’s own house rules. In-play betting is offered by GB bookmakers and is governed by the licence conditions and customer-protection duties — never “unrestricted” as a legal conclusion. Esports sit under the real-events licence like any other event. Virtual events are a separate category. Bets on politics, TV shows and novelty events are offered by GB bookmakers and no statutory prohibition was found; they sit inside each operator’s terms.

Betting exchanges run under the betting intermediary licence. Rates, commission and rules specific to exchanges are stated only from each exchange’s terms; the exchange is not a fixed-odds bookmaker and its mechanics (back and lay, liability rather than stake) are not what this page covers. Spread betting that is not a financial product sits inside General Betting Duty and the Gambling Commission’s general betting framework. Financial spread betting — the kind where losses can exceed the deposit — is regulated by the Financial Conduct Authority, not the Commission, and is a separate product with a separate licence.

No statutory cap on stakes in sports betting exists. Operators set their own maximum stakes and may restrict individual customers. The Commission’s stake-related rules concern the conduct of the bet (for instance, withdrawal of a market on a voided event), not the maximum size of a stake. The bookmaker chooses.

Player protection: GAMSTOP, limits and help

GAMSTOP is the national multi-operator online self-exclusion scheme, mandatory for online operators since 31 March 2020. Self-exclusion periods are 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, offline self-exclusion process. Every GB-licensed online operator is a GAMSTOP member; that is the basic test of whether a site is licensed at all.

Deposit limits under the Remote Technical Standards (RTS 12) require operators to offer customers a gross deposit limit on a fixed time frame. The first changes have applied since 31 October 2025; a second phase was postponed to 30 September 2026, and whether it is live is not established. There is no state-set ceiling on deposits or losses; limits are the customer’s choice, and the operator’s job is to make the limits easy to set. Loss limits, wagering limits and time-out facilities sit alongside deposit limits on every GB-licensed site.

Help outside the operators is the National Gambling Helpline (run by GamCare), the GambleAware website, the NHS gambling clinics network, and Gamblers Anonymous. The Commission’s rules require licensed operators to point customers at these services and to interact with customers showing signs of harm. A customer who feels the limits are not being enforced has a right to take a complaint to the operator first, then to an approved alternative dispute-resolution body, then to the Commission.

Payments: credit cards banned, debit cards and bank transfers clean

Credit cards have been banned for gambling in Great Britain since 14 April 2020 (LCCP condition 6.1.2). The ban covers credit-card-funded payments through an e-wallet: a customer topping up PayPal from a credit card and then depositing to a bookmaker is using a credit card, and the bookmaker that processes the payment is in breach. Debit cards, instant bank transfers and most e-wallets are not covered by the credit-card ban and are routine at every GB-licensed operator. There is no state list of permitted payment methods, no British named-account rule, and no rule for or against cryptocurrency deposits at licensed operators; payments are described from each operator’s terms only.

Identity verification before the first deposit means no anonymous play. Source-of-funds questions at higher spend are normal under the anti-money-laundering rules; the operator asks because the rules require it, and a refusal to answer is a refusal to play.

Advertising, the ASA, and the “no mixed products” rule

Advertising is not the Commission’s job to licence. Non-broadcast advertising runs through the CAP Code, broadcast through the BCAP Code, both enforced by the Advertising Standards Authority (ASA), alongside the LCCP marketing conditions the Commission sets. CAP Code section 16 requires marketing to be socially responsible, to be of no strong appeal to under-18s, and not to feature anyone who is or seems to be under 25 gambling or playing a significant role (with an exception for marketing placed where a bet can be made directly). The rule concerns who may appear in the advert, not who may place a bet.

Promotion rules since 19 January 2026 are the live frame. Two rules govern what a GB-licensed bookmaker may put in front of a customer: the 10x cap on wagering requirements, and the ban on mixed-product offers. The cap does not apply to free bets with no rollover condition, and the rule does not cap the money value of a bonus. The ban on mixing covers offers that require a customer to gamble on two or more product types (betting plus bingo, betting plus casino, betting plus lottery); a sports free bet that does not require casino play is fine. A “bet £10 on football to get 50 free spins” is not.

“Whistle-to-whistle” — no betting advertising on TV from five minutes before to five minutes after a live sporting event, before the 9pm watershed — is an industry code, not a statute. The Premier League clubs’ voluntary withdrawal of gambling sponsorship from the front of matchday shirts takes effect from 2026/27; sleeves and pitchside hoardings remain. Operators are responsible for what their affiliates publish, and the Commission has sanctioned operators for affiliate content it did not control.

Tax: the player pays nothing on winnings, the operator pays duty on profits

The player pays no tax on betting winnings in Great Britain. That is the general position and it is not tax advice; a professional gambler should ask HMRC or a qualified adviser. General Betting Duty is the operator’s tax on gross profits from betting, 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% (HM Government policy paper of 26 November 2025). Spread betting has its own rates (3% on financial spread betting, 10% on other). Until 1 April 2027 the remote rate stays at 15%. Whether operators pass duty on through odds is not established and never the customer’s problem on the page.

Offshore: why a GB licence matters, and what the customer loses without one

Providing gambling facilities in Great Britain without the licence the 2005 Act requires is an offence under section 33 — up to 51 weeks’ imprisonment, a fine up to level 5, or both; six months in Scotland. The offence is aimed at the operator. No offence aimed at a customer who simply bets on an unlicensed site was found, and the proper framing is unlicensed = no GAMSTOP coverage, no Commission complaints route, no approved alternative dispute resolution, no British consumer redress if funds are withheld, not bound by the 10x bonus cap, not bound by the £150 vulnerability check. The licensed side carries verification before the first bet and a smaller product catalogue; the unlicensed side carries none of the protections and the real risk that funds are not recoverable. Neither is “the safe choice” by default; the licensed side is the regulated choice, with the protections that go with it.

Enforcement against unlicensed operators is disruption, not blocking. The Commission issues cease-and-desist notices, refers sites to search engines, works with registrars, hosting providers and payment companies to take sites offline, and has been given or is about to receive court-order DNS blocking powers. There is no general ISP blocking in operation at the time of writing, and the proper phrasing is powers granted or imminent, not ISP blocking live. Honest framing of an unlicensed site is the loss of the protections, not its illegality.

Responsible Gambling and the Real Cost of a Promotion

What a promotion asks of a customer, and what it asks of a problem gambler

A welcome offer is a marketing tool that turns a sign-up into a first deposit, a first deposit into a first bet, and a first bet into a habit of play. The 10x cap and the no-mixed-products rule reduce the harm a promotion can do by capping the turnover a customer must run through the site and by closing off the casino funnel. They do not remove the marketing itself. A £40 free bet is still £40 of stake the customer will bet with, whether or not it returns, and the expiry window is the lever that turns an unused free bet into a felt loss. That is the structural shape of every promotion on this page, and it is what the safer-gambling tools are designed to interrupt.

The safer-gambling tools at a GB-licensed operator are: a deposit limit (a gross limit on a fixed time frame), a loss limit, a wagering limit, a time-out, and GAMSTOP self-exclusion. The operator is required to offer each one, and required to make them easy to find. The customer is required only to use them. A customer who has registered with a deposit limit, a loss limit and a time-out has changed the cost the promotion can charge, because the limit is a ceiling the bonus cannot push past.

The single most expensive thing on this page is a promotion a customer feels they have to clear. A £20 bonus with a 10x wagering cap requires £200 of qualifying bets before the money is withdrawable; a customer who would not otherwise have bet £200 has been turned into someone who did. The 10x cap reduces that figure from what it could have been, and the no-mixed-products rule keeps the £200 inside sports betting; it does not stop the customer from running the £200 to clear the bonus, nor from doing it on markets with a margin wider than the ones they would have chosen without the bonus. The protection is real, and it is partial.

What help looks like when the limits have stopped working

GamCare runs the National Gambling Helpline and a network of online and face-to-face support services. GambleAware funds treatment and research and is the public-information point for anyone asking where to start. The NHS operates gambling clinics in several regions, free at the point of use, with referrals from a GP or self-referral accepted. Gamblers Anonymous runs peer-support meetings on the model of similar fellowships. A customer who has self-excluded via GAMSTOP has taken the strongest option the licensing system offers, and the operator is prohibited from sending marketing, from allowing deposits and from accepting bets for the duration.

The Commission’s role is the licensing and complaint-handling backstop. A customer who has exhausted an operator’s complaints route may refer a dispute to an approved alternative dispute-resolution body; the Commission’s website lists them. The Commission will not adjudicate a dispute for a customer, but it will consider whether an operator has breached a licence condition. The path for an individual with a complaint is operator first, ADR second, Commission third.

Marketing to under-25s, and what the rules actually say

The CAP Code section 16 rule on under-25s concerns who may appear in an advertisement, not who may place a bet. The minimum age to bet is 18. The two are different rules, and the under-25 rule is a marketing rule the ASA enforces, not a betting rule the Commission enforces. A licensed operator verifies every customer’s age before the first deposit, and the verification does not stop at the deposit; a customer who passes the deposit check has still got to pass any subsequent check the operator runs, and the operator’s ongoing monitoring is one of the LCCP conditions.

The voluntary withdrawal of gambling sponsorship from the front of Premier League matchday shirts from 2026/27 is a separate matter. It is not a statute. It does not change the rules on betting. It reduces the visibility of gambling brands on television coverage of Premier League football. Sleeves and pitchside hoardings remain. Other leagues have their own positions, and a reader who watches Championship football will see different sponsors on different shirts.

Bonuses, Free Bets and What They Cost

The shapes a GB bookmaker’s promotion takes

A promotion in this market takes one of a small number of shapes. Each shape carries a different cost.

A free bet is the most common welcome offer. The customer places a qualifying bet at a stated minimum price (often 2.0 / 1/1), receives free bet tokens of a stated value (often £20 to £60), and uses the tokens on a market at a stated minimum price (often 1.5 / 1/2) within an expiry window (often 7 days). The free-bet stake is not returned with a winning bet; the customer receives winnings only. A £10 free bet at 5.0 returns £40 if it wins. A £10 free bet at 5.0 returns nothing if it loses.

A stake-back offer refunds a losing stake as a free bet. Hollywoodbets’ “stake back up to £30” on a first losing accumulator is the shape: the customer places a 3-leg acca at minimum combined odds of 4/1, the bet loses, and the operator credits a free bet of up to £30. The free bet carries its own expiry and its own minimum-odds condition. The customer loses the qualifying stake by definition (the bet has lost) and recovers a fraction of it.

A deposit bonus credits a bonus equal to a multiple of the customer’s deposit, subject to a wagering requirement. A 100% deposit bonus of £20 with a 5x wagering requirement means the customer must stake £100 in qualifying bets before the bonus and winnings are withdrawable. The 10x cap limits how heavy that requirement can be. A £10 bonus at 50x — once a routine shape — is now unlawful.

A price boost raises the odds on a named selection or a named accumulator, with a stated maximum stake. The customer places the bet at the boosted odds; the boost is the promotion. There is no wagering requirement on a price boost; the winnings are withdrawable as cash. The cap on the boost is the maximum stake; the cap on the value is the maximum winnings the operator has priced into the boost.

An accumulator insurance refunds a losing accumulator as a free bet, subject to conditions (number of legs, minimum combined odds, settled within a stated window). BoyleSports’ Acca Insurance is the shape: minimum stake £5, minimum odds 1/2, maximum refund £20, expires in 7 days, settled on the same day. The customer loses the stake, recovers a free bet, and the free bet carries its own expiry.

An enhanced odds offer boosts the odds on a first bet for new customers. The customer places a qualifying bet at the boosted odds and receives winnings at the boosted price. The stake is returned with a win; enhanced odds are not the same as a free bet, because the customer’s stake is on the line.

What the 10x cap means in practice, with worked arithmetic

The 10x wagering cap, in force since 19 January 2026, applies to the bonus base research names — the bonus, or the bonus plus the deposit, depending on the offer. The arithmetic below works a representative offer of a £20 bonus with a 10x wagering requirement, a 30-day expiry and a 1.5 (1/2) minimum price on the bet placed with the free bet. It shows how the cap shapes what the customer must do.

The required turnover is £20 × 10 = £200. At a stake of £10 per qualifying bet, the customer must place 20 bets before the bonus and any winnings from it are withdrawable. At a stake of £5 per qualifying bet, the customer must place 40 bets. The 10x cap is the ceiling on this multiple; offers that previously carried 30x, 40x or 50x turnover are no longer lawful. An offer that carries no wagering requirement — the common “free bet, no rollover” welcome — sits outside the cap entirely, because there is no multiple to cap.

The expected cost of clearing a bonus depends on the margin of the market the customer bets into. At a market margin of 5%, the expected cost of clearing a £200 turnover is £200 × 5% = £10. At a market margin of 8% — the kind of margin the bookmaker applies to accas and less-popular markets — the expected cost is £200 × 8% = £16. The customer does not pay this cost as a fee; the cost is the share of every pound staked that the bookmaker keeps on average. It is the silent price of clearing the bonus. The bonus is worth £20 in cash terms; the cost of converting it to withdrawable cash is between £10 and £16, depending on the markets the customer chooses.

The honest conclusion is the band. A £20 bonus with a 10x wagering requirement costs the customer between £10 and £16 in expected value to clear, depending on market choice, before the £20 is theirs. A £20 free bet with no wagering requirement, used once at minimum odds of 1.5 with the stake not returned, is worth £20 × (5.0 − 1) ÷ 5.0 × 0.95 = £15.20 on average at a market margin of 5% — that is, the free bet returns £15.20 in expected profit to the customer across many uses. The number is an average across many bets and many customers, not a guaranteed outcome for any single punter. The honest reading of a promotion is the gap between the headline figure and the figure after turnover and margin, and that gap is wider than the marketing admits.

Why the stake of a free bet is not returned

A free bet is a token the operator credits, not a stake the customer has paid for with cash. When the customer uses the free bet on a market and the bet wins, the operator pays the winnings at the stated odds; the free bet token itself is consumed. The mechanic is the same as a bookmaker’s free-race entry at a racecourse: the bookmaker credits the entry, the customer uses it, and the entry does not come back. The reason is the cost to the bookmaker. A free bet that returned its stake on a win would cost the bookmaker the stake plus the winnings, and the headline figure on the welcome offer would have to be smaller to stay profitable. The Commission’s stance is that the free bet is a marketing credit whose stake is consumed; the customer gets the winnings; the operator keeps the difference.

The bookmaker that does return the free-bet stake — a rarer shape — charges for it implicitly. The headline free bet is smaller, the minimum odds on the bet placed with the free bet is higher, or the qualifying bet is harder to place. The shape exists; it is not the default.

Minimum odds: what the gate actually does

A minimum-odds gate is the condition that the qualifying bet (or the bet placed with the free bet) must be placed at odds of 1.5 (1/2), 2.0 (1/1) or another stated minimum. The gate exists to prevent the customer from achieving the wagering requirement by betting on heavy favourites whose margin is narrow and whose chance of winning is high — the kind of bet that would clear the bonus cheaply and leave the operator paying out. A 2.0 (1/1) minimum is a routine gate on the qualifying bet; a 1.5 (1/2) minimum is a routine gate on the bet placed with the free bet.

The gate works against the customer in two ways. It forces the customer into markets with wider margins (the bookmaker’s margin on a 2.0 shot is wider than its margin on a 1.2 shot, because the wider-price market has less liquidity and less price competition). And it reduces the chance of the qualifying bet winning, which means the customer pays for the free bet with the stake rather than with a winning bet. The combination is the cost of clearing the offer, and the cap on the cost is the 10x wagering rule.

Expiry, and the felt loss of an unused free bet

A free bet expires. The expiry is the lever that turns an unused free bet into a felt loss. Most welcome offers in this market carry a 7-day expiry from credit; a 14-day or 30-day expiry is the more generous end. The customer who fails to use the free bet within the window has paid for the bonus with the qualifying stake and has nothing to show. The expiry exists because the bookmaker writes the free bet into its liabilities on the day of credit, and a free bet the customer uses in week four is a free bet the bookmaker has had to account for across a month of going. The 7-day norm is the bookmaker’s compromise between giving the customer time and keeping the liability short.

A customer who wants to keep the value of a free bet has to plan for the expiry. The free bet is used on a market the customer was going to bet on anyway, at minimum odds the offer allows, within the window the offer allows. Anything else is a worse use of the token.

The Top 10: Each Reviewed Bookmaker on Its Own Terms

The ten bookmakers below are reviewed in the order research routes them. Each review carries the brand, the licence holder that runs it, what the operator’s own terms say on the offer and the platform features that matter to a customer who already bets, and a verdict on what the brand is and is not for.

Hollywoodbets

Hollywoodbets International UK Limited holds Gambling Commission remote licence 53028 (categories: general betting standard, real events). The site is hollywoodbets.co.uk. The welcome offer credits a stake-back free bet of up to £30 on a first losing accumulator: deposit £10 or more by card, place a 3-leg accumulator at minimum combined odds of 4/1, settle within 7 days, and the operator credits one free bet per customer on the losing stake. The promotion is shaped for the customer who bets accumulators anyway, and the customer’s expected loss is the qualifying stake. A customer who would not otherwise bet a 4/1 acca has been turned into one by the offer, and that is the cost the marketing does not state.

The platform carries the betting exchange’s nearest cousins in the fixed-odds world: a sportsbook with football, horse racing and a South African racing focus. Hollywoodbets is a South African brand that runs a GB-licensed site alongside its core market. The offer is the only shape the welcome takes; there is no £40 in free bets headline. A customer who wants a larger headline credit at lower qualifying risk looks elsewhere.

Verdict: for the punter who bets small-stake accas and wants the safety net of a stake refund on the first one. The £30 cap is the ceiling, and a customer whose first acca is a five-leg at 20/1 will not see a £30 free bet.

Fitzdares

Fitzdares Limited holds Gambling Commission remote licence 400 (categories: general betting standard, real events). The site is fitzdares. The welcome offer’s shape is published in the app and governed by customer terms, and the operator’s positioning is the premium end of the GB market: a smaller customer base, higher stake limits, a focus on horse racing and a payment set that includes Apple Pay, Mastercard and Visa, with Visa withdrawals usually same-day and Mastercard withdrawals up to 48 hours. The site carries a more limited sportsbook than the larger operators; the offer is the hook, and the customer is expected to be a higher-stake horse-racing punter rather than a casual accumulator bettor.

The platform trades on its exclusivity. The payment set is narrower than the larger operators’; the sports coverage is narrower too. A customer who wants a deep in-play offering on South American football, or a wide pre-match card on lower-tier tennis, will not find it here.

Verdict: for the horse-racing customer who wants same-day withdrawals on Visa and a bookmaker that takes larger stakes than the mainstream. The offer is a premium-positioning hook, not a headline-credit grab; a casual punter pays for that positioning in the sportsbook’s narrower catalogue.

Tote

TDCO Limited holds Gambling Commission remote licence 54779 (categories: general betting standard, real events, with the Tote’s separate pool-betting licence). The site is tote.co.uk. The Tote runs pool betting on British and Irish racing, alongside its fixed-odds sportsbook; the welcome offer sits on the sportsbook side and is governed by the operator’s terms. The Tote’s distinct product is the pool — a dividend-paying pool bet on a race where the customer bets into a pool and is paid a share of it — and that product is not what this page covers. A customer who wants the pool side has come to the right operator; a customer who wants a fixed-odds sportsbook has come to a smaller one.

The platform is horse-racing led. Football and other sports are covered but not as the main event. The Tote is one of the older names in British betting and a publicly visible brand in racing; its presence on this page is for the customer who wants to bet pools rather than fixed odds.

Verdict: for the pool-betting customer who wants a dividend-paying product on British and Irish racing alongside a smaller fixed-odds sportsbook. The Tote is not the right operator for a customer whose only bet is a Saturday accumulator on the Premier League.

BetVictor

BV Gaming Limited holds Gambling Commission remote licence 39576 (categories: general betting standard, real events). The site is BetVictor. The welcome offer is shown in the app and governed by the operator’s customer terms. BetVictor’s promotional catalogue is regular price boosts, acca offers and free bets on selected events, with a sportsbook that runs football, horse racing, tennis and a deep in-play offering. The welcome is smaller than some competitors’ but the running promotions are denser; a customer who bets regularly will see more value in the day-to-day boosts than in the headline credit.

The platform is one of the older names in British online betting. The payment set is mainstream; the sports coverage is broad; the in-play product is solid. BetVictor is not the largest operator on the British market and does not have the marketing budget of the biggest names, but its regular-customer promotions are competitive.

Verdict: for the regular punter who wants a denser catalogue of running price boosts and acca offers than the welcome credit alone implies. The welcome is the entry; the running promotions are the value.

Bet600

Tyche Tech Limited holds Gambling Commission remote licence 44731 (general betting standard licence). The site is Bet600. The welcome offer requires at least 5 qualifying single bets of £10 or more at minimum odds of 2.0 (Evens) within the first 7 days of registration, after which one £10 free bet is credited. The shape is heavy on qualifying: the customer must stake £50 in qualifying bets at a fairly wide minimum price before any credit arrives. The £10 free bet, used on a market at 1.5 (1/2) or greater with the stake not returned, is worth around £5 in expected profit to the customer at a market margin of 5%.

The platform is a smaller operator with a sportsbook that runs the mainstream sports. The welcome offer is the weakest on this page in headline terms — £10 in free bets after £50 in qualifying bets — and the customer is paying a high qualifying cost for a modest credit.

Verdict: not for the customer who wants a generous welcome credit. Bet600’s offer is for the punter who would be betting £50 anyway in the first 7 days and wants the £10 free bet on top.

Fitzwilliam Sports

SBKI Limited holds Gambling Commission remote licence 48760 (general betting standard licence). The site is Fitzwilliam Sports. The operator is described on its own homepage as a Dublin bookmaker with capped membership; the welcome is a “High Stakes Welcome” subject to compliance criteria. The shape is the opposite of the mainstream offers on this page: a higher-stake customer, a higher headline, a compliance check at sign-up. A customer who qualifies is a customer the operator wants; a customer who does not is a customer the operator does not serve.

The platform is horse-racing and Irish racing focused, with a sportsbook that runs the mainstream sports. The capped membership means the operator is selective about its customer base, and the welcome is the operator’s way of stating what kind of punter it wants. A casual accumulator bettor is not the target.

Verdict: for the higher-stake customer who wants a “High Stakes Welcome” and is comfortable with a compliance check at sign-up. The offer is not for the casual punter, and the capped membership is the operator’s way of saying so.

Betfair

PPB Counterparty Services Limited holds Gambling Commission remote licence 39439 (general betting standard licence). The site is Betfair. Betfair runs two products: the betting exchange, where customers back and lay against each other, and the Betfair Sportsbook, a fixed-odds product alongside it. The welcome offer is on the sportsbook side; the exchange is a separate product with separate mechanics (back and lay, commission, liability) and separate promotions. The sportsbook runs in-play betting, Bet Builder, free live streaming of UK and Irish horse racing and football within the app, and a 90 Minute Payout market on selected football events.

The platform is one of the largest in British betting. The sportsbook is competitive; the exchange is unique among the operators on this page; the live streaming product is broad. The welcome is the entry to the sportsbook; the exchange is where the customer goes if they want to lay bets or trade positions.

Verdict: for the customer who wants both a sportsbook and an exchange under one roof, with live streaming of UK and Irish racing and football. The sportsbook welcome is the entry; the exchange is a separate product with separate mechanics, and a customer who has never used an exchange should read the exchange’s own terms before betting.

Smarkets

Smarkets (Malta) Limited holds Gambling Commission remote licence 39173 (remote betting intermediary licence). The site is Smarkets. Smarkets runs the betting exchange, with the SBK sportsbook as a fixed-odds product alongside it. The SBK sportsbook’s welcome offer is a £20 first deposit and £20 bet at minimum odds of 3.0 for £60 in free bets within 48 hours; the sportsbook carries Cash Out, Bet Builder and live horse racing streams. The 3.0 minimum is the highest of the welcome offers on this page and the qualifying bet is the hardest to win, which means the customer is paying for the £60 free-bet credit with the chance of a £20 losing bet.

The platform is exchange-led. The sportsbook is the secondary product; the exchange is where the operator competes with Betfair. The welcome is on the sportsbook side, not the exchange; the exchange’s mechanics (back and lay, commission, liability) are not what this page covers.

Verdict: for the customer who wants an exchange-led platform with a fixed-odds sportsbook alongside it, and a welcome that asks for a £20 qualifying bet at the highest minimum odds of any offer on this page. The £60 headline is the largest of the set; the qualifying cost is the highest of the set.

LiveScore Bet

LiveScore Betting and Gaming (Gibraltar) Limited holds Gambling Commission remote licence 56859 (general betting standard licence). The site is LiveScore Bet. The payment set is one of the broadest on this page: debit cards (Visa and Mastercard), Apple Pay, PayPal, Pay by Bank (Open Banking) and Revolut Pay. The welcome offer is governed by the operator’s customer terms and is shown in the app.

The platform is the LiveScore media brand’s sportsbook, leveraging the LiveScore scores-and-stats product. The sportsbook runs football as its main sport, with the second-screen experience the brand is built around. The payment set is the differentiator; the welcome is mainstream.

Verdict: for the customer who wants a sportsbook with a LiveScore-flavoured live experience and a payment set that includes Pay by Bank, Apple Pay and Revolut Pay. The welcome is the entry; the payment set is the operator’s distinguishing feature.

bet365

Hillside (UK Sports) ENC holds Gambling Commission remote licence 55148 (general betting standard licence). The site is bet365. The platform carries Bet Builder+ (combining markets from one event into a single bet, available pre-match and in-play), Super Boosts, Winnings Boosts on Bet Builders and selected singles, and daily Bet Boosts. The welcome offer is shown in the app and governed by customer terms. The in-play product is the deepest on this page; the Bet Builder+ product is the most-developed single-event builder; the daily Bet Boosts catalogue is broad.

The platform is the largest GB-licensed sportsbook. The features are the differentiator; the welcome is the entry. A customer who wants the deepest in-play product and the broadest Bet Builder has come to the right operator; a customer who wants a simpler offer has come to the largest marketing budget.

Verdict: for the customer who wants the deepest in-play offering, the broadest Bet Builder and the densest catalogue of daily price boosts on this page. The welcome is mainstream; the platform is the reason to bet here.

The Calculation: What a £20 Bonus with a 10x Wagering Requirement Costs in Expected Value

The prescribed calculation for this page is the bonus-turnover scenario. The inputs are the offer terms research describes — a £20 bonus, a 10x wagering multiple, a minimum odds of 2.0 on the qualifying bet, a 7-day expiry — and the 10x wagering cap in force since 19 January 2026. The arithmetic belongs to the page; the conclusion is the band’s condition and the result, not a single number.

The required turnover is the bonus base multiplied by the wagering multiple. At a £20 bonus base and a 10x wagering multiple, the required turnover is £20 × 10 = £200. At a stake of £10 per qualifying bet, the customer must place 20 bets to clear the bonus. At a stake of £5 per qualifying bet, the customer must place 40 bets. The 10x cap is the ceiling on this multiple; offers that previously carried 30x, 40x or 50x turnover are no longer lawful, and the £200 figure is the upper bound of what a £20 bonus can require.

The expected cost of clearing the offer is the required turnover multiplied by the margin of the market the customer bets into. At a market margin of 5% — the kind of margin a mainstream football 1X2 market runs at — the expected cost is £200 × 5% = £10. At a market margin of 8% — the kind of margin an accumulator or a less-popular market runs at — the expected cost is £200 × 8% = £16. The customer does not pay this cost as a fee; the cost is the share of every pound staked that the bookmaker keeps on average across all outcomes. It is the silent price of clearing the bonus, and the Commission cap does not affect it — the cap limits the multiple, not the margin on each market.

The honest conclusion is the band, not a single figure. A £20 bonus with a 10x wagering requirement, cleared at a stake of £10 per bet on markets with margins between 5% and 8%, costs the customer between £10 and £16 in expected value to clear before the £20 is theirs. The bonus is worth £20 in headline credit; the cost of converting it to withdrawable cash is between £10 and £16, depending on the markets the customer chooses. The cost is an average across many bets and many customers, not a guaranteed outcome for any single punter. The 10x cap is what makes this offer lawful; a 50x offer at the same bonus base would have required £1,000 of qualifying bets and an expected cost between £50 and £80, which is the shape of promotion the rule now bans.

Putting It Together: Which Offer Suits Which Punter

A welcome offer is a single product. The customer who wants the largest headline credit wants Smarkets’ £60 in free bets for a £20 qualifying bet at minimum odds of 3.0 — and accepts that the qualifying bet is the hardest on this page to win. The customer who wants the lowest qualifying cost wants Hollywoodbets’ stake-back free bet on a first losing accumulator, where the qualifying bet is a 3-leg acca at minimum combined odds of 4/1 and the credit is up to £30 on the loss. The customer who wants a mainstream welcome wants BetVictor’s app-published offer, or Unibet’s £40 in free bets (on a £20 qualifying bet at minimum odds of 2.0), which is the shape BetVictor’s mainstream welcome takes.

The customer who cares about the platform wants bet365’s in-play product, Betfair’s exchange and live streaming, or Smarkets’ exchange. The customer who cares about the payment set wants LiveScore Bet’s Pay-by-Bank and Revolut Pay, or Fitzdares’ same-day Visa withdrawals. The customer who wants the smallest operator with a specific positioning wants Fitzwilliam Sports’ “High Stakes Welcome” or the Tote’s pool-betting product.

The customer who wants to minimise the cost of clearing a promotion wants the offer with no wagering requirement. Every welcome offer on this page except the deposit-bonus shapes is a free bet with no rollover, and the cost is the difference between the free-bet stake not returned and the winnings. A £10 free bet at 5.0 returns £40 if it wins; the expected value at a market margin of 5% is £10 × (5.0 − 1) ÷ 5.0 × 0.95 = £7.60. The customer has paid £10 (in qualifying stake) and received £7.60 in expected free-bet value, for a net cost of £2.40. That is the shape of a no-rollover welcome offer at mainstream market margins.

The customer who cares most about safer gambling wants the operator that makes the limits easy to set and the GAMSTOP registration one click away. Every GB-licensed operator on this page is required to offer deposit, loss and wagering limits and to be a GAMSTOP member; the practical difference is in how the limits surface in the app and how the operator interacts with a customer who has set one. The Commission’s enforcement on this is one of the things the licence buys.

Frequently Asked Questions

How do you use a promo code on a betting site in Great Britain?

A promo code is a string of letters or numbers the operator prints in a corner of its advert or its homepage, and the customer enters it at the sign-up or deposit stage to claim the offer attached to it. The code itself does nothing — the offer it unlocks is governed by the operator’s customer terms, and the terms decide what the customer must do to qualify, what they receive and when it expires. Never print or share a promo code on this page; the offer’s value sits in the terms, not the code.

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

The Gambling Commission’s promotion rules, in force since 19 January 2026, cap the wagering requirement on a betting bonus at 10x the bonus base. A £20 bonus with a 10x wagering requirement requires £200 of qualifying bets before the bonus and winnings are withdrawable. Whether the cap applies to free bets with no wagering condition is not established, and the rule does not cap the absolute money value of a bonus.

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

The minimum odds is the lowest price at which the qualifying bet, or the bet placed with the free bet, must be placed — for example minimum odds of 2.0 (1/1) on the qualifying bet, or 1.5 (1/2) on the bet placed with the free bet. The wagering requirement is the multiple of the bonus the customer must stake in qualifying bets before the bonus and winnings are withdrawable — for example 5x or 10x. Both conditions raise the cost of clearing the offer by forcing the customer into markets with wider margins.

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

A free bet is a token the operator credits at its own cost, not a stake the customer has paid for in cash. When the customer uses the free bet on a market and the bet wins, the operator pays the winnings at the stated odds; the free bet token itself is consumed. The reason is the cost to the bookmaker — a free bet that returned its stake would cost the bookmaker the stake plus the winnings, and the headline credit would have to be smaller to stay profitable. The Commission’s stance is that the free bet is a marketing credit whose stake is consumed.

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

No. The Commission’s promotion rules since 19 January 2026 ban mixed-product offers — an offer that requires the customer to gamble on two or more product types such as betting, casino, bingo and lottery, for example “bet £10 on football to get 50 free spins”. What stays legal is single-product promotions: a sports free bet, an acca boost, a refund on a losing sports accumulator. The ban covers the tying, not the running of separate sports and casino offers.

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

The Commission’s public register is searchable by business name, trading name, domain or account number. The register is the only reliable test of whether a brand holds a GB licence; the domain (.com or .co.uk) proves nothing. The register lists the licence holder’s legal name, the licence categories (general betting standard real events, virtual events, betting intermediary, pool betting), the account number and the site domain. Quote no licence count without the register’s access date, and never call any single brand “the only” licensed one — the register lists hundreds of account holders, and a feature in a guide is not a licence.
