Non Gamstop betting sites — the licence, the cost, the gaps
Available in USA bookmaker a reader can actually open an account with is a licensed one. That sentence is the spine of what follows, because every other choice — which offer to take, how big a stake to risk, what recourse the punter has when a payout is delayed — sits inside it. The headline question is whether any site that takes bets from Great Britain can sit outside GAMSTOP, and the answer in the facts is short: no Great Britain-licensed online operator sits outside the scheme, by licence condition, and any site without a Gambling Commission licence runs without the protections the licence buys. The page below is built around that difference, because the only real comparison is between the protections a licence gives and the things a player forfeits without it.
The figures and licence numbers below are checked against the Gambling Commission’s public register as of 27 October 2026, and operator terms are taken from each brand’s own pages on the same visit. Where a price or a margin would date inside a week, the comparison is described in words rather than digits.
The legal frame: what a Gambling Commission licence requires
Every commercial bookmaker offering remote betting to customers in Great Britain needs an operating licence from the Gambling Commission, a non-departmental public body sponsored by the Department for Culture, Media and Sport. The Commission licenses under the Gambling Act 2005, which covers England, Scotland and Wales. Northern Ireland has its own older law, so a “GB licence” regulates Great Britain only and never Northern Ireland. Since the Gambling (Licensing and Advertising) Act 2014, the licence is required at the point of consumption: a brand based in Curaçao, Malta or Gibraltar still needs a Commission licence to take remote bets from a customer sitting in Manchester, and a foreign licence is not a substitute. There is no state monopoly, no cap on the number of licences, and several brands often sit under one licence holder.
The Commission issues several licence categories that matter for a sports punter. Remote general betting standard (real events) is the workhorse licence for any online bookmaker offering pre-match and in-play markets on actual sporting events. Remote general betting standard (virtual events) is a separate licence for computer-simulated events. Remote betting intermediary is the licence held by betting exchanges, where customers back and lay against each other rather than against the firm. Remote pool betting covers pari-mutuel pools such as Tote products on horse racing. Pool betting on horse or dog racing taken off-course is its own licence category and its own duty. Financial spread betting on price moves in shares, indices and forex is regulated by the Financial Conduct Authority, not the Commission — and that is why Spreadex holds both an FCA authorisation for spread betting and a Commission licence for fixed-odds sports betting: one regulator for the financial product, one for the bet on the match.
Section 36 of the Gambling Act 2005 sets the remote betting standard, and section 33 makes providing gambling facilities without the required licence a criminal offence for the operator, carrying up to fifty-one weeks’ imprisonment or a level-5 fine on summary conviction in England and Wales, and six months in Scotland. No offence aimed at a customer who merely places a bet on an unlicensed site was found: the law targets the operator, not the punter. That asymmetry is the reason the page never writes that betting on an offshore site is “legal for the player”, and never writes that it is illegal. What is established is what the player loses by sitting outside the regime, and that is the comparison below.
The Commission’s public register can be searched by business name, trading name, domain or account number, and is the whole test of whether a brand holds a licence. A licensed operator can run on .com as well as .co.uk, so the domain proves nothing on its own. The register entry carries the licence categories, the trading names and the website addresses the Commission knows about, and it changes when licences are added, varied or revoked. No single bookmaker is “the only” licensed brand; the register lists many, and the ten covered here are ten of them.
What the licence costs the bookmaker — and so what it gives the punter
A Commission licence is conditional, and the conditions are what the page is really comparing. The headline conditions on the customer-facing side sit in the Licence Conditions and Codes of Practice and the Remote Technical Standards.
Identity has to be verified before the first deposit or first bet, and since 7 May 2019 that verification has to include the customer’s name, address and date of birth — a check that fires for free bets and bonus credits, not only for paid stakes. No licensed bookmaker offers anonymous accounts; the registered account is the customer record.
Age is set at eighteen. A customer below eighteen cannot open an account, and an account opened by someone who turns out to be below eighteen is closed and any stake returned.
GAMSTOP integration is a mandatory licence condition for every online operator, in force since 31 March 2020. Each login and each new sign-up is checked against the GAMSTOP register, and a registered self-excluder is blocked from creating new accounts and from accessing existing ones. There is no opt-out. The mechanics of the scheme are described in the section on responsible gambling below.
A financial vulnerability check runs against licensed remote betting when a customer’s deposits minus withdrawals exceed £150 in any rolling thirty-day window. The check, in force under LCCP condition 3.4.4 from 30 August 2024 and applied to that threshold from 28 February 2025, runs against public records such as bankruptcy registers and county court judgments. It is not an income check and not a credit reference check. Financial risk assessments — the more searching affordability checks that the press has called “affordability checks” — sit in a staged plan the Commission set out on 7 July 2026, with no start date yet announced; the page therefore writes that the high-end checks are announced and staged, not that they are in force.
Deposit limits under RTS 12 are mandatory: every licensed remote operator must offer a customer-set gross deposit limit on a fixed time frame, and the first changes have been in force since 31 October 2025, with a second phase that has been postponed to 30 September 2026. The limits are the customer’s choice; Great Britain sets no state ceiling on what a player may deposit or lose, and the limits above the regulated minimum are the punter’s own.
Bonus rules in force since 19 January 2026 cap wagering requirements on bonuses at ten times the bonus amount, and ban mixed-product promotions — an offer that demands play on two or more product types, such as “bet on football to get free spins”, is no longer permitted at a GB-licensed operator. Whether the cap applies to free bets with no wagering condition, and any cap on the bonus’s money value, are not yet established.
Credit cards have been banned for gambling in Great Britain since 14 April 2020 under LCCP condition 6.1.2, and the ban covers credit-card-funded payments through an e-wallet: paying with a credit card via PayPal or Skrill is still paying by credit card, and a licensed operator will refuse the deposit. Debit cards and bank-based methods are not covered by the ban.
What an unlicensed site forfeits
The same conditions are what an offshore site, licensed in Curaçao or Malta and accepting GB customers without a Commission licence, is not bound by. A bookmaker without a GB licence does not run GAMSTOP checks; does not verify identity before the first deposit in the way the LCCP demands; does not run the £150 financial vulnerability check; does not apply the ten-times wagering cap on bonuses; does not observe the credit-card ban; and does not offer the Commission’s approved alternative dispute resolution route when a payout is disputed. The Commission’s enforcement toolkit against an unlicensed operator is disruption rather than blocking: cease-and-desist notices, search-engine referrals, work with registrars, hosts and payment providers, and court-order DNS blocking powers the Commission has been given or is about to receive. ISP-level blocking of unlicensed domains is not described as in force on this page, because the powers exist without the wholesale block the question implies.
The honest framing is therefore simple: a GB-licensed book means checks, limits, GAMSTOP coverage, the bonus cap and the dispute-resolution route, together with the verification a punter undergoes before the first bet. An unlicensed book means none of those protections, with the additional risk of funds being withheld because there is no British consumer redress. Neither is “the safe choice” by default; the question is what trade-off the punter accepts.
What GAMSTOP is, how it blocks, and what it does not do
GAMSTOP is the national multi-operator online self-exclusion scheme in Great Britain, run by The National Online Self Exclusion Scheme Limited, a company registered in England and Wales under registered number 10504973 and based in Harrogate. The service is free: a registrant pays no price to set an exclusion. The scheme is a mandatory licence condition for every online operator, so any bookmaker licensed to take remote bets from a customer in England, Scotland or Wales has to check the customer against the GAMSTOP register on every login and at every sign-up.
A registrant chooses a minimum self-exclusion period of six months, one year or five years. The six-month period is the shortest available, and a five-year period can be set to renew automatically at the end of each five-year term, with a fresh five-year minimum period beginning at the end of the last. The exclusion does not lift automatically when the minimum period ends: the registrant must contact the GAMSTOP Contact Centre and request deactivation, after which a twenty-four-hour cooling-off period applies. During that cooling-off period the request can still be withdrawn. After the exclusion is removed, GAMSTOP continues to inform operators for a further seven-year period that the person was previously self-excluded, but operators are not required to prevent access during that follow-on window — they may, and the press does not always, but the obligation is gone.
The scheme covers online sites and apps. Betting shops are covered by a separate service, Gamstop Betting Shops, which runs the same kind of check at the counter rather than at the login screen. GAMSTOP publishes that it is in use by over half a million people in the UK. A licensed bookmaker cannot promise a customer that a self-exclusion will be honoured if the customer does not register with GAMSTOP in the first place; the register is what the bookmaker checks.
The point of the scheme is exactly the point a punter searching for “non Gamstop betting sites” is testing. By licence condition, no Great Britain-licensed online operator sits outside GAMSTOP. Any site a customer can reach from Great Britain and that does not run a GAMSTOP check is, by definition, not licensed by the Commission for remote betting in Great Britain. The next question is what that unlicensed site costs the customer who joins it, and the previous section is the answer.
What an exclusion costs the customer on a licensed site
The cost runs in two directions. On the way in, registration is irreversible for the minimum period: a punter cannot shorten a six-month exclusion by appealing to the operator, because the operator is bound to refuse. On the way out, the seven-year follow-on window means that even after the cooling-off has run, the fact of the exclusion sits in the data the operator holds. Several brands ask a customer who has previously self-excluded to wait, to go through enhanced affordability checks or to be re-onboarded under stricter limits, and that is a house decision rather than a regulatory rule.
A punter thinking through what an exclusion will mean in practice has to plan for the deposit side as well. If a customer has £250 sitting in an account when the exclusion is set, that balance is real money and the operator holds it; the exclusion prevents play, not withdrawal, and the customer can usually request the balance back through the operator’s safer-gambling team. The press has covered cases where a customer expected play to be blocked while a balance was effectively stranded; the better-run sites say so on the safer-gambling page, and that is the page to read before setting an exclusion.
Responsible gambling: what every licensed book has to offer
The safer-gambling toolkit on a GB-licensed site is built from regulation, not from generosity. The mandatory elements are GAMSTOP, age and identity verification, the £150 financial vulnerability check, deposit limits and the LCCP social responsibility code; above those, operators add their own product-level controls, and the better ones describe them in plain English.
Deposit limits are the customer’s own ceiling on how much money can come in. The limit applies on a fixed time frame — typically daily, weekly or monthly — and a customer can set it lower at any time. Raising the limit usually requires a cooling-off period, which is a deliberate friction: a punter who lowers a limit wants the discipline, and a punter who raises a limit might be chasing losses. The mechanics vary by product. Free bets and bonus credits can be set against their own caps at some brands, and casino bonuses have their own.
Time-outs are short self-exclusions run by the individual operator, typically for twenty-four hours, seven days or thirty days. They do not feed into GAMSTOP and they do not appear on the Commission’s record; they are an account-level pause. Product restrictions are a more surgical tool: a customer who wants to keep betting on horse racing but stop playing online slots can ask the operator to block slots specific products, and the operator must honour the request.
Reality checks are pop-ups that interrupt play at fixed intervals and show the customer how long they have been on the product and what their session profit or loss looks like. The intervals are set by the operator within the LCCP’s minimum cadence.
Affordability signals at the £150 threshold trigger a public-record check under the financial vulnerability rule, and that check is described in the section on identity and vulnerability above. Higher spending triggers the more searching financial risk assessments the Commission has announced in a staged plan; the start date for those is not yet fixed.
Self-exclusion via GAMSTOP is the multi-operator exclusion described in its own section. Self-exclusion via the individual operator is the equivalent single-firm exclusion, and the operator must honour it.
The help services a licensed operator must link to are GamCare, which runs the National Gambling Helpline, GambleAware, the NHS gambling clinics network, and Gamblers Anonymous. GamCare’s helpline is the live route; the NHS clinics are the treatment route; both are free. The Commission’s safer-gambling pages publish the same list.
The safer-gambling pages to read before joining
A licensed operator publishes a “safer gambling” page that explains the controls in its own product. Before opening an account, a customer who cares about the toolkit should read three pages in this order: the safer-gambling page for the controls available, the responsible-gambling code section of the terms for the legal mechanics, and the bonus terms for any wagering cap the operator applies. The first page answers “what can I switch off”, the second answers “what am I agreeing to”, and the third answers “what does it cost me to clear a bonus”. A punter who reads only the bonus page gets the marketing offer without the trade-off.
The ten brands reviewed: licence, terms, and the trade-off
The ten brands below are ten of the operators on the public register that hold a remote general betting standard (real events) licence and that take customers in Great Britain. Each entry names the licence account number on the Commission’s register and the licence holder behind the brand, and each entry describes the brand’s welcome offer in the words the operator’s own terms use. The page is not a ranking: a position in the comparison is not a licence, and several brands can sit under one licence holder. The verdict at the end of each block is the page’s own judgement of the trade-off the brand asks the punter to accept.
| Brand | Gambling Commission licence | What the operator’s own terms state on the subject |
|---|---|---|
| Star Sports | 009177-R-104555-019 (account 9177) — Star Racing Limited | A trader line for opening accounts, placing bets and asking queries |
| London Bet | 066162-R-340278-004 (account 66162) — Thistle Bet Limited | 17+ App Store age rating and a self-description as licensed and regulated in the UK |
| BoyleSports | 039469-R-319383-025 (account 39469) — Boylesports Enterprise | £20 in free bets for UK players after a £10 qualifying bet; €30 in free bets after a €10 bet for Irish players |
| Hollywoodbets | 053028-R-330019-013 (account 53028) — Hollywoodbets International UK Limited | Stake returned as a free bet of up to £30 on a first qualifying losing accumulator (stake £10+, 3+ legs, odds 4/1+, settled within 7 days); one free bet per customer |
| Spreadex | 008835-R-104580-022 (account 8835) — Spreadex Limited | FCA-regulated for spread betting and Commission-regulated for fixed-odds betting; spread losses can exceed deposits |
| Sky Bet | 067370-R-341330-005 (account 67370) — SBG Sports Limited | £30 in free bets as three £10 tokens after a £5 deposit and a first single or each-way bet of 5p at odds of 1/1 or greater |
| Matchbook | 039504-R-319407-024 (account 39504) — Triplebet Limited | Remote betting intermediary licence; brand acquired by Matchbook’s parent and accounts will not transfer to Matchbook |
| NetBet | 039170-R-319343-032 (account 39170) — Netbet Enterprises Limited | Daily Boosts, Profit Boosts, free bet offers, a bet builder with instant dynamic odds and sports stats for major leagues |

Star Sports — the trader line and the racing book
Star Sports holds remote general betting standard (real events) licence 9177, and the licence holder is Star Racing Limited. The customer-facing detail that sets the brand apart is a trader line: customers can speak to a trader directly on 08000 521 321 to open an account, place a bet or ask a customer query, with email support at [email protected]. The trader model is a holdover from the on-course era, and it shows in the racing book, where the brand is closer to a traditional layers’ firm than to a slick consumer app.
The trade-off the punter accepts is the inverse of the trade-off at a pure consumer app: less product surface, more human contact. A punter who wants to talk through a bet before placing it has a route; a punter who wants a same-game multi on a Tuesday-night EFL game may find the menu thinner.
London Bet — the London-facing brand
London Bet holds remote general betting standard (real events) licence 66162, and the licence holder is Thistle Bet Limited. The brand describes itself as licensed and regulated in the UK, and the App Store listing carries a 17+ age rating. The proposition is the London-facing brand: a name that says “London” and a customer base that skews to the same.
The trade-off is a narrower product range than the major brands. A punter whose interest is mainstream racing, football and the major US sports will find what they need; a punter whose interest is in niche leagues, prop markets or live esports may find the menu short.
BoyleSports — the £20 free bet for £10
BoyleSports holds remote general betting standard (real events) licence 39469, and the licence holder is Boylesports Enterprise. The sports welcome offer for UK players is £20 in free bets when a £10 bet is placed; Irish players get €30 in free bets on a €10 qualifying bet. The Irish-UK split is real: the same brand runs different welcome mechanics in each jurisdiction, and the punter has to read the terms for the jurisdiction they sit in.
The trade-off is the standard free-bet one. A free bet’s stake is usually not paid back with a win — the punter collects the winnings, not the stake plus winnings, and a £20 free bet at even money collects £20, not £40. The punter needs to know that before counting the headline figure as cash.
Hollywoodbets — the losing-accumulator refund
Hollywoodbets holds remote general betting standard (real events) licence 53028, and the licence holder is Hollywoodbets International UK Limited. The sports welcome offer: new players who deposit £10 or more by card get their stake back as a free bet of up to £30 on their first qualifying losing accumulator. The qualifying conditions are stake £10+, three legs or more, odds of 4/1 or greater, settled within seven days. One free bet per customer.
The trade-off is the seven-day settlement window and the accumulator mechanic. A punter who backs a single at 4/1 does not qualify; the qualifying bet has to be an accumulator with at least three legs. A punter whose first bet is a single has to add legs to qualify or accept that the welcome offer does not apply. Once again, the stake of a winning free bet is not paid back, so the punter who wins collects the profit, not the stake plus profit.
Spreadex — the financial spread betting angle
Spreadex holds remote general betting standard (real events) licence 8835, and the licence holder is Spreadex Limited. The brand is regulated by the Financial Conduct Authority for spread betting and by the Gambling Commission for fixed-odds betting, and the homepage states that spread betting losses can exceed deposits. The dual regulation is the point of difference: the same firm offers a financial-instrument product (spread betting on shares, indices, forex) and a sports product (fixed-odds betting) under two regulators with two different rules.
The trade-off is the leverage on the spread side. A spread bettor who is right about a price move can make more than they staked; a spread bettor who is wrong can lose more than they deposited, and that is not a marketing line — it is the homepage statement, in plain English, before the punter opens an account. The fixed-odds sports book is a separate product with separate rules, and the punter can use one without using the other.
Sky Bet — the £30 free bet for a 5p bet
Sky Bet holds remote general betting standard (real events) licence 67370, and the licence holder is SBG Sports Limited. The welcome offer for new customers is £30 in free bets, credited as three £10 free bet tokens after a deposit of at least £5 and a first single or each-way bet of at least 5p at odds of 1/1 or greater. The 5p minimum stake is a deliberate mechanic: the firm wants a customer who has actually placed a bet, and the 5p requirement is the cheapest way to satisfy that. The 1/1 minimum odds is a way to filter out no-risk qualifying bets.
The trade-off is the free-bet stake-not-returned rule and the three-token split. A punter who wants to use the full £30 on one bet has to do it as three bets, not one, and each token has its own minimum-odds rule. A punter who treats the £30 as one figure is in for a small surprise.
Matchbook — the betting exchange
Matchbook holds remote betting intermediary licence 39504, and the licence holder is Triplebet Limited. The same licence holder acquired the Betdaq brand, and Betdaq accounts will not transfer to Matchbook. A betting intermediary runs on a different mechanic from a traditional book: customers back and lay against each other, and the firm takes a commission on net winnings rather than a margin baked into every price. That is why Matchbook’s prices are often bigger than a traditional book’s on the same selection: the firm is not the counterparty.
The trade-off is the lay side. A punter who has only ever placed back bets has to learn the lay side to use an exchange well, and a punter who never goes past the back side is paying over the odds for a product they could use more cheaply elsewhere. The commission structure is the second trade-off: Matchbook’s headline commission is on net winnings, not on turnover, and a punter with a long losing run pays nothing in commission on the losing bets.
NetBet — the boosts and the bet builder
NetBet holds remote general betting standard (real events) licence 39170, and the licence holder is Netbet Enterprises Limited. The offer sits in Daily Boosts, Profit Boosts and free bet offers, a bet builder with instant dynamic odds and sports stats for major leagues. The bet builder with instant dynamic odds is the headline product point: the price on a same-game multi updates as the punter adds legs, so the punter sees what they are buying before they confirm.
The trade-off is the boost mechanics. A boosted price is still a price on the same market, and the margin that sits inside it is the margin of the boosted market, not the margin of the un-boosted one. A punter who chases boosts without checking the underlying market is paying the boost tax without the boost return.
DragonBet — the Welsh markets
DragonBet holds remote general betting standard (real events) licence 64908, and the licence holder is DragonBet Ltd. The product line features Welsh football and rugby markets, racing, American football, in-play betting and bet builder markets. The Welsh markets are the point of difference: a brand that lists the Cymru Premier and the Welsh rugby regions at a level of detail that a generalist book cannot match.
The trade-off is depth elsewhere. A punter whose interest is Welsh sport has found a brand that takes that interest seriously; a punter whose interest is the depth of a Championship relegation market may find the menu thinner than a major book. The bet builder and in-play product is present, so the everyday tools are there.
Fafabet — Best Odds Guaranteed on racing
Fafabet holds remote general betting standard (real events) licence 57385, and the licence holder is Taichi Tech Limited. The headline racing product is Best Odds Guaranteed on UK and Irish horse racing win and each-way bets from 9am on race days: if the starting price is bigger than the original price, the bigger odds are paid. BOG is a routine racing feature at the major books, and a smaller brand offering it is signalling it wants to be taken seriously on racing.
The trade-off is the timing rule. BOG at Fafabet applies from 9am on race days; a punter who takes a price the night before is on the night price, not the SP, and the BOG protection does not bite on the bigger SP unless the bet was placed after 9am. The punter has to plan the time of the bet, not just the bet itself.
The cost: what a £500 monthly budget actually spends
The expected-loss calculation gives a punter a way to think about what a budget buys on a typical book. The arithmetic uses a turnover of £500 — an illustrative monthly budget, since Great Britain has no state-set deposit or loss ceiling — staked once, and an illustrative two-way market at decimal odds 1.90 / 1.90 (fractional 9/10, an example, not a quoted price). Two-way means two outcomes, like a tennis matchup or a basketball handicap after the spread.
The payout share of that market is 1 ÷ (1/1.90 + 1/1.90) = 1 ÷ (2/1.90) = 1.90 ÷ 2 = 0.95, and the margin is 1 − 0.95 = 0.05, or 5%. The expected cost of clearing the budget once on that market is turnover × margin = £500 × 0.05 = £25, with the result stated as a band rather than a single figure because the cost on any individual month depends on the actual prices the punter takes and the markets they bet on; a £500 turnover on a market with a 4% margin costs £20, and a £500 turnover on a market with a 7% margin costs £35.
The comparison the punter should make is between this £20–£35 band on a low-margin market and the headline offer at the brand they are joining. A £30 free-bet welcome at Sky Bet, a £20 free-bet welcome at BoyleSports, a £30 free-bet refund at Hollywoodbets on a losing accumulator: each one looks competitive on the headline, and each one is paid back as a free bet whose stake is not returned. The punter who reads the headline as cash has over-counted what the offer is worth by exactly the stake, and a £30 free bet at even money collects £30, not £60.
The other comparison is the speed at which the budget gets spent. A £500 turnover on a market with a 5% margin is a £25 expected cost whether the punter places one £500 bet or fifty £10 bets, but the variance is wider in the second case: more bets means more variance, more chances for a losing run to swallow the budget before the bettor finds their edge. The arithmetic says the cost is the same; the experience says the latter punter will feel the cost more sharply.
The deepest-cost comparison sits on the bonus side. The 19 January 2026 cap on wagering requirements at ten times the bonus amount means a £10 bonus at 50x needs £500 of bets — and at ten times, no more than £100. A punter who is offered a “100% bonus” with a fifty-times wagering requirement is being offered an offer that the cap makes non-compliant at a GB-licensed book; the same offer at an unlicensed book is the cost the punter is paying for sitting outside the regime.
The mechanics a punter should know
A few mechanics sit underneath every bet, and a punter who knows them is worth picking up a free bet on.
Odds and prices. British bookmakers price in fractional form by default (5/1, 11/4, evens) and in decimal form (6.00, 3.75, 2.00) on the same selection. The decimal price is the fractional price divided by the other number plus one, so 5/1 becomes 5 ÷ 1 + 1 = 6.00, and 11/4 becomes 11 ÷ 4 + 1 = 3.75. A price shorter than evens is “odds-on”. The return on a winning single is stake × decimal odds, and the profit is stake × (decimal odds − 1). The return on a winning accumulator multiplies the decimal odds of the legs together, and a four-leg accumulator with legs at 2.00, 3.00, 1.50 and 4.00 has a combined price of 2.00 × 3.00 × 1.50 × 4.00 = 36.00.
Margin. A two-way market at 1.90 / 1.90 has a margin of 5% and a payout share of 95%. A three-way 1X2 market at 2.10 / 3.40 / 3.60 has a payout share of 1 ÷ (1/2.10 + 1/3.40 + 1/3.60) = 1 ÷ (0.4762 + 0.2941 + 0.2778) = 1 ÷ 1.0481 = 0.954, so a margin of about 4.6%. The bookmaker keeps the difference between every unit staked and the share returned as profit, on average across many bets. A punt on the same match at a sharper book has a tighter margin; a punt at a softer book has a wider one.
Each-way. An each-way bet is two bets of equal stake: one on the win, one on the place. The total stake doubles. Place terms vary by race and operator, and the each-way leg pays a fraction of the win price (a quarter or a fifth, usually) depending on the number of runners.
Free bets. A free bet’s stake is not returned on a win, in the usual rule; the punter collects the profit, not the stake plus profit. A £10 free bet at 3/1 collects £30, not £40. The stake-not-returned rule is what makes a free bet worth less than its headline figure, and the free-bet-value formula gives a published estimate of how much less. Some books run free-bet promotions that pay back the stake as cash; the punter reads the terms.
Best Odds Guaranteed. A racing feature: if the starting price on a UK or Irish horse is bigger than the price the punter took, the bigger price is paid. The punter collects the SP, not the taken price, on the winning leg. Fafabet applies the rule from 9am on race days; the major books apply it from a similar morning time. Ante-post bets (those placed before the final field is declared) are usually excluded, and the punter checks the small print.
Cash out. A cash-out is the bookmaker buying the punter’s bet back at a price of its own at that moment. The cash-out price is built from the current prices on each leg, with the bookmaker’s own margin baked in, and the punter who cashes out is taking the book’s price rather than letting the bet run. The price looks worse than a swap would be, because it is.
Betting exchanges. Matchbook is the exchange covered above. Customers back and lay against each other; the firm takes a commission on net winnings. The price on a popular selection at an exchange is often bigger than the price at a traditional book, because the counterparty is another punter, not the firm.
Spread betting. Spreadex’s other product. The punter bets a stake per unit of price movement on a financial instrument; a £5-per-point stake on a 100-point move wins £500, and a 100-point move the other way loses £500. The losses can exceed deposits, and that is the homepage statement, not a marketing line.
How a punter verifies a licence
The Commission’s public register is the whole test. The punter searches by business name, trading name, domain or account number; the register returns the licence categories, the licence holder’s company name, the trading names the licence covers and the website addresses the Commission knows about. A match between the search result and the brand the punter is about to join is the verification. A mismatch — a brand whose domain is not on the register, a register entry that lists a different trading name — is a red flag.
The ten brands reviewed above are all on the register under the licence numbers in the table. The numbers are Commission account numbers, which are the public-facing identifier on the register; the longer licence codes include the year and sequence the Commission uses internally, and the punter reads the account number on the register, not the longer code.
A licensed brand will publish its licence status somewhere on its site, often in the footer of the homepage and on the safer-gambling page. The footer statement is not the verification — the register is — but it is the place the punter starts the check.
What the offshore book does not give up
The honest framing has two sides. The unlicensed book has its own attractions: bigger welcome packages, looser verification at sign-up, no GAMSTOP check to block a self-excluder who has set a minimum period and now wants back in. Those attractions are the cost of the regime: the price the punter is paying for sitting outside GAMSTOP, outside the £150 vulnerability check, outside the ten-times bonus cap, outside the dispute-resolution route and outside the British consumer redress that comes with a Commission licence. The punter who takes the offshore book is buying those attractions and paying for them with the protections the licence would have given.
The other side is that the protections are not free for the licensed book. Identity verification before the first deposit is a friction the unlicensed book does not impose. The £150 vulnerability check is a friction the unlicensed book does not run. The ten-times bonus cap is a friction the unlicensed book does not observe. A punter who values the absence of friction above the presence of protection will land on the offshore book; a punter who values the presence of protection will pay the friction and stay with the licensed book. The page does not choose for the punter.
What the punter does next
Three checks. First, the licence check on the Commission’s public register, against the account number the brand publishes in its footer. Second, the safer-gambling page for the controls the operator offers, and the deposit-limit mechanic for the limits the punter sets. Third, the bonus terms for any wagering requirement on a welcome offer, with the cap in mind. A punter who has done those three checks has read the page the offer sits on, and the offer is what it was.
Frequently asked questions
Does GAMSTOP cover every betting site licensed in Great Britain?
Yes. GAMSTOP is a mandatory licence condition for every online operator licensed by the Gambling Commission, in force since 31 March 2020, and every operator covered in this comparison participates. Any site a customer can reach from Great Britain and that does not run a GAMSTOP check is not licensed by the Commission for remote betting in Great Britain. The mechanics of the scheme and the periods on offer are described in the section above.
What does a player lose by betting on a site without a Gambling Commission licence?
The list is concrete. No GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld, and no obligation on the operator to apply the ten-times bonus cap or run the £150 financial vulnerability check. The player is also outside the credit-card ban and outside the LCCP’s social-responsibility code. Section 33 of the Gambling Act 2005 makes providing the facilities without the licence an offence for the operator; no offence aimed at the player was found.
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, and is the whole test of whether a brand holds a licence. The register lists the licence categories, the licence holder’s company name and the trading names and website addresses the Commission knows about. A licensed operator will publish its account number on the site, often in the footer; the punter enters that number on the register and reads the match. No single bookmaker is “the only” licensed brand; the register carries many.
Which tools for controlling play does a licensed bookmaker have to offer?
GAMSTOP is the headline; deposit limits, time-outs, product restrictions, reality checks and self-exclusion at the operator level are the rest. The £150 financial vulnerability check fires automatically when deposits minus withdrawals exceed £150 in a rolling thirty-day window; higher spending triggers the more searching financial risk assessments the Commission has announced in a staged plan. GamCare, GambleAware, the NHS gambling clinics and Gamblers Anonymous are the help services a licensed operator must link to.
What does the financial vulnerability check look at, and when does it apply?
It applies to licensed remote betting when a customer’s deposits minus withdrawals exceed £150 in any rolling thirty-day window, in force under LCCP condition 3.4.4 from 30 August 2024 and applied to that threshold from 28 February 2025. The check runs against public records such as bankruptcy registers and county court judgments; it is not an income check and not a credit reference check. Higher spending triggers the more searching financial risk assessments the Commission set out on 7 July 2026 in a staged plan, with no start date yet fixed.
