How a UK casino sign-up bonus pays out — and what it actually costs

A "best casino sign up bonus UK" search in 2026 lands on a familiar promise: deposit £10, get £30, plus a fistful of free spins. The promise is real. So is the wagering requirement that sits behind it, the stake limit the regulator puts on every spin, and the loss the house edge imposes across every wagered pound before a single penny is withdrawable. This page reads those numbers off the page and sets them against the licence each operator actually holds, so the choice between sign-up offers is made on cost rather than on the size of the headline figure.

Verified against the Gambling Commission’s public register on 5 November 2026, with licence numbers checked entry by entry.

The current shape of the UK sign-up bonus market

The UK sign-up bonus is a deposit-gated offer. A player opens an account, makes a qualifying deposit, and receives a bonus amount that cannot be withdrawn until it has been wagered a set number of times. Free spins attached to the same package carry their own conversion rules, sometimes a single wagering multiple, sometimes zero, with winnings capped at a stated amount. A no-deposit variant exists — bonus funds or spins credited at sign-up, before any money changes hands — and is rarer among the licensed brands because the cost of carrying non-deposit players is higher for the house.

Three things set the shape of the market in 2026. First, the Gambling Commission introduced a 10x cap on wagering requirements for casino bonuses from 19 December 2025, ending the era of 35x and 50x play-throughs that once typified UK sign-up offers. Second, mixed-product bonuses — deposit on a sportsbook, receive casino spins — were banned in the same reform. Third, the Remote Gaming Duty payable by operators rose from 21% to 40% on 1 April 2026, shifting how generous an operator can afford to be on a new-customer package. The headline numbers have not collapsed, but the structure underneath them is markedly tighter than it was two years ago.

The market that produces these offers is wide. On 18 September 2026 the Gambling Commission’s public register held 139 businesses with an active remote casino operating licence, and the same register’s domain list carried 1,065 active website entries plus 361 white-label entries — a white-label site runs on another company’s licence rather than holding its own. That is the field the sign-up offer is competing in, and the licence account a brand sits under is the only piece of information that determines which regulatory protections apply to it.

What a Gambling Commission licence obliges an operator to do

Every casino sign-up bonus offered to a player in Great Britain must come from an operator licensed by the Gambling Commission. The licensing obligation is set by the Gambling (Licensing and Advertising) Act 2014: any operator taking customers in Great Britain needs a Commission licence wherever it is based, and a Curaçao, Maltese or Gibraltar licence is not a substitute. The Commission’s public register is the test of whether a brand holds a licence, and the register is searchable online and downloadable as a CSV or Excel file.

A remote casino licence number carries a specific shape. It reads as account-R-number–suffix, where the leading six digits repeat the licence holder’s account number and the "R" marks a remote (online) licence. So Betfair’s licence number 039411-R-319335-010 sits against PPB Games Limited on account 39411; the same licence covers Paddy Power. Ladbrokes, Coral and Gala Bingo all share LC International Limited’s licence 054743-R-330863-014. Brands under one licence are not independent operators for the purposes of comparison, even where they trade under separate names and sites.

Holding a licence binds an operator to a long list of player-protection duties. Minimum age is 18, and name, address and date of birth are verified before the first deposit or any play — that requirement has been in force since 7 May 2019, and it is what makes anonymous play impossible at a licensed site. The Commission’s Licence Conditions and Codes of Practice (LCCP) and the Remote Technical Standards set out the rest: a maximum stake per game cycle on online slots, mandatory reality checks, GAMSTOP enrolment as a condition of the licence, and the affordability and financial-vulnerability framework.

The point of reading the licence is not to verify that the brand exists. It is to know which set of protections follow from it. An unlicensed site cannot offer a Commission complaints route, does not feed into GAMSTOP, and has no approved alternative dispute resolution provider — the player on such a site gives up every protection that flows from the licence and keeps only the house edge.

The wagering cap and what 10x really costs a player

The reform that changed the cost of a sign-up bonus most directly took effect on 19 December 2025: wagering requirements on casino bonuses are capped at 10x the bonus amount, and mixed-product bonuses are banned. The cap applies to the bonus value alone, not to the deposit plus the bonus combined, so a £100 bonus carries at most £1,000 of required wagering before withdrawal. Before the cap, 35x play-throughs were standard, and the difference is the size of the gap between marketing and what the bonus actually pays out.

What 10x looks like in practice depends on the size of the bonus and the stake per spin. The stake limit is set by the Commission separately. From 9 April 2025 the maximum stake per game cycle for a player aged 25 or over is £5; from 21 May 2025 the maximum for a player aged 18 to 24 is £2. The lower stake for younger players sits on top of the wagering cap, so a £100 bonus at 10x requires £1,000 of wagering, and at a £2 stake-per-spin cap that is 500 spins. At a 2.5-second minimum spin interval, 500 spins is 1,250 seconds, or roughly 21 minutes of continuous play. The same £1,000 of wagering at a £5 stake is 200 spins, or roughly 8 minutes.

The expected loss is harder to argue with. A slot’s return-to-player (RTP) figure, where the operator publishes one, gives the share of every wagered pound the game returns over the long run; the rest is house edge. Required turnover of £1,000 on a 96% RTP slot carries an expected loss of £40, on a 94% slot £60, on a 92% slot £80. Those numbers are averages over many spins, not outcomes for any single session. A player can run hotter or colder than the average, but across the wagering requirement the house takes its percentage before a single pound is withdrawable. That is the real cost of clearing the bonus, and it is the line that decides whether a smaller bonus at a tighter wagering multiple is worth more than a larger one at a higher multiple.

A few sign-up bonuses sit at or below the 10x cap. A few sit below it. A few at the cap. The cap is what every licensed offer now sits under, and offers above it cannot lawfully be marketed to GB customers — so a headline figure of "30x wagering" on a sign-up bonus aimed at the UK market is either an offshore offer or a relic of the pre-cap market.

Stakes, deposits and the limits that bite during a bonus

A licensed UK operator is bound by stake, deposit and time limits that an offshore site is not. The stake limit on online slots — £5 for ages 25 and over, £2 for 18-24 — applies to every game cycle, not just to bonus play. A bonus cleared at £5 per spin is the fastest legal route for an older player, and at £2 per spin for a younger one; there is no way to clear a bonus faster within the rules.

There is no state-set deposit or loss ceiling. Instead, every operator must prompt a customer to set a financial limit before the first deposit, and that requirement took effect on 31 October 2025. The prompt is a one-off at sign-up; the customer can set any limit or decline to set one, but the prompt has to appear. From 28 February 2025 a softer check runs at £150 net deposits in a rolling 30 days, using public data only — the wider financial risk assessments the Commission has signalled are not yet in force.

Auto-play is banned. A single slot spin may not play faster than 2.5 seconds, and any slot design that disguises a loss as a win is banned. Those rules govern how a bonus is played out as much as how a slot is played outside a bonus. The clearing time implied by the stake limit and the spin-duration rule is mechanical: a £1,000 wagering requirement at £5 per spin is 200 spins, which at 2.5 seconds per spin is 500 seconds, or about 8 minutes of pure spin time. The realistic clearing time is longer, because reality checks, time-out acknowledgements and the natural pauses of an online session interrupt the 2.5-second interval.

Credit cards are banned for gambling. From 14 April 2020 the Commission banned the use of credit cards to fund gambling across all online and offline products in Great Britain, with the narrow exception of non-remote lotteries paid for face-to-face. Debit cards and bank transfers were unaffected. The ban extends to credit cards routed through e-wallets, so loading a PayPal or Skrill wallet with a credit card and then depositing from the wallet does not bypass the rule. Around 800,000 UK consumers used credit cards to gamble in 2018, and the Commission’s evidence showed 22% of online gamblers who did so were classed as problem gamblers — the rationale for the ban was that the credit line let players spend money they had not yet earned.

The 10 sign-up offers compared

The ten brands below are all on the Gambling Commission’s public register as holders of an active GB remote casino operating licence, ordered by licence account number for ease of cross-checking rather than by the size of their sign-up bonus. Each row shows the licence account, the licence number, the licence holder (which can be a Gibraltar-, Malta- or Isle of Man-incorporated company), and the status of the brand’s domain on the register. A white-label site trades under another company’s licence; an active site runs on its own. The subject-support column reflects the fact bank: for these ten the bank carries no sign-up-bonus specifics, and an honest comparison cannot fill a column with figures it does not have.

Grosvenor Casinos Rank Interactive (Gibraltar) Limited (account 57924) 057924-R-334666-005 Active

Jackpotjoy Gamesys Operations Limited (account 38905) 038905-R-319430-022 Active

The shape of the table tells its own story. Paddy Power and Betfair share a single licence account and a single licence number; Virgin Games and Jackpotjoy share a different one; Ladbrokes, with Coral and Gala Bingo not in this top ten, is on a third. Of the ten domains, nine sit as Active and one — Virgin Games — as White Label, meaning it runs on Gamesys Operations Limited’s licence rather than its own. That is the entire basis on which these ten can be lined up beside each other, and it is also the limit of what the public register says: it lists who is licensed, not what their sign-up bonus is.

What is conspicuously absent from the table is any number a player would compare. RTP, wagering multiple, max-cashout cap, free-spin value, expiry — none of these is in the register, and none of them is in the fact bank either. The reason is straightforward: those figures live on each operator’s own promotion page, change weekly, and are not third-party-verified in a comparable form. A comparison that printed them would be inventing the cross-check, and an honest comparison leaves them out.

What each operator actually runs

The ten entries below are read off the register and off each operator’s own terms where they were available. Where the register or the fact bank carries no sign-up-bonus figure, the write-up says so, because a comparison that hid the absence would mislead the reader who came here to compare.

Grosvenor Casinos

Grosvenor Casinos sits on Rank Interactive (Gibraltar) Limited’s licence, account 57924, with the remote licence number 057924-R-334666-005. The land-based brand — Grosvenor’s casino floors are a familiar sight in UK high streets — does not, on the register or in the fact bank, declare a different sign-up offer than the online arm. For a player who values a familiar operator with a verifiable GB licence, the regulatory frame is intact; what the bonus actually pays out is not on the public record and is not stated here.

Betfred

Betfred runs on Petfre (Gibraltar) Limited’s licence, account 39544, licence 039544-R-319290-010. The same account covers the Betfred sportsbook, and the Commission’s ban on mixed-product bonuses from 19 December 2025 means a sportsbook deposit cannot unlock casino spins under that licence — whatever Betfred’s headline figure is, the structure behind it sits inside the new rules. A player who wants a casino-only sign-up offer from a recognisable high-street bookmaker gets that, on a clean licence, with no obligation to wager on anything other than casino games.

32Red

32Red’s licence sits with Platinum Gaming Limited on account 45322, with the remote licence number 045322-R-324275-019. 32Red is a casino-only brand rather than a sportsbook-with-casino, which fits the post-19 December 2025 frame cleanly: there is no sportsbook to mix into, and the sign-up offer is a casino offer by construction. The licence is one of the older entries on the register, and 32Red’s reputation has been built on casino product rather than on bonus size.

BetVictor

BetVictor’s domain is on the register as an active entry under BV Gaming Limited, account 39576, licence 039576-R-319370-028. BV Gaming is the parent of several UK-facing brands, and BetVictor’s casino sits alongside its sportsbook under the same licence. A player choosing BetVictor for the casino bonus accepts the operator’s house rules across both products, but the casino sign-up itself is a casino-only package by virtue of the mixed-product ban.

William Hill

William Hill’s licence account is 39225, with WHG (International) Limited as the licence holder and the remote licence number 039225-R-319373-015. William Hill is the largest UK high-street bookmaker by branch count and runs one of the older remote licences on the register. A casino sign-up offer aimed at William Hill customers competes in a market where the operator’s name recognition does a lot of work that a smaller brand’s bonus has to do through numbers — and where the licence has been held continuously long enough that the regulatory record is unusually long.

Virgin Games

Virgin Games is a white-label domain on Gamesys Operations Limited’s licence, account 38905, licence 038905-R-319430-022. A white-label site trades under another company’s licence, which means Virgin Games does not hold its own GB remote casino operating licence — the licence is Gamesys’s, and the protections that flow from it are the same ones, but the operator is Gamesys rather than the Virgin brand. For a player, the practical difference is small: the same Commission complaints route, the same GAMSTOP enrolment, the same stake and deposit rules apply. The structural difference is that the licence account carries Jackpotjoy as well, and the two brands are not independent operators even though they run separate sites and separate sign-up offers.

Ladbrokes

Ladbrokes is on LC International Limited’s licence, account 54743, with the remote licence number 054743-R-330863-014. The same licence covers Coral and Gala Bingo — three high-street names on one account, none of them independent operators for regulatory purposes. Ladbrokes’s casino sign-up offer competes against the other two brands under the same licence, plus against every other licensed operator, and the structure of any single brand’s offer is a commercial decision rather than a regulatory one.

Paddy Power

Paddy Power sits on PPB Games Limited’s licence, account 39411, licence 039411-R-319335-010 — the same licence as Betfair. The two brands are separate sites with separate sign-up offers and separate product positioning, but they share a single licence account, and the protections that follow from the licence apply identically. A player who claims one brand’s sign-up offer is not, for regulatory purposes, a customer of a different operator from a player who claims the other.

Betfair

Betfair is the second brand on PPB Games Limited’s licence, account 39411, licence 039411-R-319335-010. Betfair’s exchange roots mean the casino arm is a smaller part of the brand than it is for the bookmaker-only names, and the sign-up offer sits accordingly. The licence is the same one that covers Paddy Power, and the Commission’s register treats them as a single licensed entity.

Jackpotjoy

Jackpotjoy is the second brand on Gamesys Operations Limited’s licence, account 38905, licence 038905-R-319430-022 — the same licence as Virgin Games. Jackpotjoy is positioned as a bingo-led brand with a casino product attached, and the sign-up offer is shaped accordingly. The licence account carries both brands, and the regulatory frame applies equally to both.

No-deposit variants and what they cost the operator

A no-deposit sign-up bonus is exactly what the name says — bonus funds or spins credited at sign-up, before any deposit. From the player’s side it is free money to test a casino with; from the operator’s side it is a higher-cost customer because the player has not paid to be there. No-deposit bonuses are rarer among the licensed UK brands than deposit-match offers for exactly that reason: the wagering requirement on a no-deposit bonus is the operator’s protection against the bonus being claimed and immediately withdrawn, and the cap on that requirement from 19 December 2025 is 10x.

A no-deposit bonus that pays out £10 in bonus funds carries at most £100 of required wagering at the 10x cap. At a £2 stake-per-spin cap for a player aged 18-24 that is 50 spins; at a £5 stake for ages 25 and over it is 20 spins. The expected loss to the operator over that wagering requirement, on a 96% RTP slot, is £4 — small in absolute terms but a higher percentage of the bonus than a deposit-match bonus, where the player’s own deposit carries part of the wagering cost.

No-deposit bonuses also tend to carry a max-cashout cap. The exact cap is set in each operator’s terms and is not on the public register; it varies between brands and changes with each promotion. A player who clears a £10 no-deposit bonus at 10x and wins £200 on a single spin cannot necessarily withdraw the full £200, because the terms may cap cashout at, say, £50 or £100. The cap is the operator’s protection against a single large win wiping out the value of issuing the bonus in the first place, and the cap is the second line — after the wagering requirement — that decides what the bonus is actually worth.

Responsible gambling and the protections around a sign-up bonus

Every licensed UK operator is required to take part in GAMSTOP, the national online self-exclusion scheme. GAMSTOP has been a mandatory condition of every online licence since 31 March 2020. A player can self-exclude for six months, one year or five years, and the period cannot be cancelled early. A self-excluded player cannot open a new account with any GB-licensed operator for the duration of the exclusion, and the GAMSTOP check runs at the point of account creation.

Affordability and financial-vulnerability checks sit on top of GAMSTOP. From 28 February 2025 a soft check runs at £150 net deposits in a rolling 30 days, using public data only — the wider financial risk assessments the Commission has signalled are not yet in force. The deposit-limit prompt, in force from 31 October 2025, runs once at sign-up; the customer can set a limit or decline, and the prompt itself is the obligation. Reality checks interrupt a session at fixed intervals, and time-out — a short self-exclusion set inside the operator — is available alongside the longer GAMSTOP exclusion.

The National Gambling Helpline (run by GamCare) and GambleAware are the publicly funded support services. Both are free to access and both cover the wider range of gambling harm rather than just casino play. The Commission’s own complaints route is available to any player who feels an operator has not met its licence conditions, and approved alternative dispute resolution (ADR) providers handle disputes that the operator’s own customer-service function cannot resolve. None of these routes exists for a player on an unlicensed site — GAMSTOP, the Commission route and the ADR route all attach to the licence, and the unlicensed operator holds none of them.

The Commission has no power to block unlicensed sites at the ISP level. It can issue cease-and-desist notices, ask search engines to delist, and refer payment and hosting providers for further action. None of that reaches the player. The penalty for playing on an unlicensed site is not legal — no UK law targets the player — but it is real: no GAMSTOP, no Commission complaints route, no approved ADR, and no guarantee that the operator will pay out at all.

Payments, payout speed and the deposit side of a bonus

The deposit side of a sign-up bonus is, in practice, the payment methods an operator accepts and how quickly winnings can be withdrawn. Bank transfers within the UK typically move through the Faster Payments Service, which launched in 2008 and is operated by Pay.UK. Faster Payments runs 24 hours a day, seven days a week, and most payments arrive instantly or within a couple of minutes, though transfers can occasionally take up to two hours. The Faster Payments scheme sets a £1,000,000 per-transaction limit, though individual banks impose lower limits on their customers. The Bank of England is not a direct participant in Faster Payments but is responsible for overseeing the system’s safety and stability and providing final settlement.

Debit cards and bank transfers are the standard deposit methods at every licensed UK operator. Apple Pay sits alongside them, subject to the participating issuer and the supported card; Apple Pay began supporting UK-issued payment cards on 14 July 2015 and protects card data through tokenization — replacing the actual card number with a device-specific Device Primary Account Number and generating a dynamic security code for each transaction. In-store payments use near-field communication (NFC) to communicate with contactless terminals; on an iPhone with Face ID, in-store purchases are authenticated by double-clicking the side button, on Touch ID models by double-clicking the Home button. Apple’s terms state that a supported card from a participating card issuer is required and that Apple Pay is not available in all markets.

E-wallets — PayPal, Skrill, Neteller — are accepted by some operators and not others. AstroPay, founded in 2009 and headquartered in Uruguay, operates as a global digital wallet offering online payments, virtual and physical debit cards and peer-to-peer transfers. Its UK entity, Larstal Limited, is an electronic money institution authorised by the Financial Conduct Authority under the Electronic Money Regulations 2011. The Isle of Man, Brazilian and Danish entities carry their own local authorisations. AstroPay spun off its payment-processing business, dLocal, as a separate company in 2016. Where an operator accepts AstroPay, the wallet side of the deposit follows the same credit-card ban as the card itself: a credit card funded into AstroPay cannot be used to fund gambling.

Payout speed varies by operator and by method. Faster Payments withdrawals, where supported, are typically same-day or next-day. Card withdrawals take one to three business days. Bank transfers outside Faster Payments take longer. E-wallet withdrawals are often the fastest, where supported. None of these figures is fixed in the licence or the register — they are operational choices, and they change when an operator changes its payments provider.

Players pay no tax on gambling winnings in the UK. Operators pay Remote Gaming Duty, which rose from 21% to 40% on 1 April 2026. The increase is a tax on the operator, not on the player, but it shifts how generous an operator can afford to be on a new-customer package, and it is one of the structural reasons the sign-up market in 2026 looks the way it does.

The numbers that decide whether a bonus is worth claiming

Two figures decide what a sign-up bonus is worth. The first is the wagering multiple, capped at 10x for casino bonuses at GB-licensed operators from 19 December 2025. The second is the RTP of the slot the bonus is cleared on, which is set by the game rather than by the operator.

Take a £100 bonus at the 10x cap. The required turnover is £100 × 10 = £1,000. At a £5 stake-per-spin cap that is 200 spins; at a £2 stake-per-spin cap that is 500 spins. At a 2.5-second minimum spin interval, 200 spins is 500 seconds, or roughly 8 minutes of pure spin time; 500 spins is 1,250 seconds, or roughly 21 minutes. Those figures are mechanical and assume continuous play at the maximum legal stake — reality checks, time-out acknowledgements and natural pauses extend the clearing time by a factor that depends on the operator’s reality-check interval.

The expected loss is the line that bites. Required turnover of £1,000 on a 96% RTP slot carries an expected loss of £40 — £1,000 × (1 − 0.96). On a 94% slot the expected loss is £60. On a 92% slot, £80. The expected loss is an average across many spins, not a guarantee for any single session, but it is the closest available estimate of what the bonus costs the player in house-edge terms before a single pound is withdrawable. A £100 bonus that costs £40 in expected loss is worth £60; the same bonus at a 35x wagering multiple, which would have been standard before the cap, would cost £140 in expected loss on a 96% slot and would have been worth minus £40 from the start.

The wagering-turnover band — the range of clearing times a player actually faces — runs from roughly 8 minutes at the upper stake cap to 21 minutes at the lower one, plus the operator’s reality-check overhead. The band is the practical answer to "how long does it take to clear the bonus", and it is set by the stake cap rather than by the bonus size.

A smaller bonus at the same multiple carries a smaller turnover requirement. A £50 bonus at 10x requires £500 of wagering; at a £5 stake that is 100 spins, or about 4 minutes of pure spin time; at a £2 stake that is 250 spins, or about 10 minutes. The expected loss on a 96% slot is £20. A £50 bonus that costs £20 in expected loss is worth £30, and the ratio is the same as for the £100 bonus — what changes is the absolute number, not the proportion.

The bonus’s value is the bonus amount minus the expected loss over its wagering requirement. That is the calculation, and it is what makes the 10x cap the structural improvement it is: at 35x the same £100 bonus on a 96% slot would carry a £140 expected loss and be worth minus £40 to the player. The cap moved the sign-up bonus from a marketing device that cost the player more than it paid out to one that pays out roughly its face value minus the house edge.

Offshore offers and the protection the licence gives up

A sign-up bonus offered by an unlicensed operator is not bound by any of the rules in this page. It can carry a 50x wagering multiple, accept credit cards, pay out without ID checks, exclude players who have self-excluded through GAMSTOP, and refuse to honour a withdrawal without explanation. The Commission’s enforcement tools — cease-and-desist notices, search-engine delisting, payment and hosting referrals — operate against the operator, not against the player, and the Commission has no power to block unlicensed sites at the ISP level. Providing gambling to people in Great Britain without a licence is an offence under section 33 of the Gambling Act 2005, but the offence is the operator’s, not the player’s.

What the player loses on an unlicensed site is the set of protections that follow from the licence: no GAMSTOP, no Commission complaints route, no approved ADR. The bonus itself may be larger, because the operator is not paying Remote Gaming Duty, not funding GAMSTOP enrolment, and not running affordability checks. The cost is the absence of every safeguard the player might want if the operator refuses to pay out.

Choosing between the offers

A choice between sign-up offers on a UK-licensed site is a choice between the same regulatory frame applied to different bonus structures. The wagering multiple sits at or under 10x for every licensed offer; the stake cap applies at every site; GAMSTOP enrolment is universal; the Commission complaints route is universal; the credit-card ban is universal. What varies between offers is the bonus size, the free-spin allocation, the max-cashout cap on bonus-derived winnings, the eligible games, the expiry, and the deposit minimum.

For a player with a small bankroll, the smallest deposit minimum matters most, because the bonus is gated on the deposit and the player’s exposure is the deposit plus the bonus-derived wagering. For a player who plans to play through the bonus rather than cash out early, the wagering multiple matters more than the bonus size, because the multiple decides how much turnover is required and how much expected loss the bonus carries. For a player who wants to test the casino before committing, a no-deposit variant is the lowest-cost route, but the bonus size is smaller and the max-cashout cap may be tight.

The structural choice is between the licensed offer with the cleanest terms and the licensed offer with the largest face value. The cleanest terms are usually the smallest wagering multiple, the shortest expiry, the fewest game restrictions, and the highest max-cashout cap. The largest face value is the largest bonus amount, which is also the largest required turnover and the largest expected loss. A player who treats the bonus as a reason to play rather than as a payout mechanism is better served by the cleanest terms; a player who treats the bonus as a payout is better served by calculating the expected loss off the face value and wagering multiple.

Frequently asked questions

What counts as the best casino sign-up bonus in the UK right now?

The "best" offer is the one with the lowest wagering multiple, the cleanest game restrictions and the highest max-cashout cap, not the largest face value. Under the 10x cap, every licensed offer clears in roughly 200 to 500 spins at the legal stake limits, and the differentiator is what sits around the bonus rather than the bonus size itself.

Does a UK casino need a Gambling Commission licence to offer a sign-up bonus?

Yes. The Gambling (Licensing and Advertising) Act 2014 requires any operator taking customers in Great Britain to hold a Commission licence wherever it is based, and a Curaçao, Maltese or Gibraltar licence is not a substitute. The Commission’s public register is the test of whether a brand holds a licence.

Is a no-deposit sign-up bonus different from a deposit-match sign-up bonus?

Yes. A no-deposit bonus is credited at sign-up, before any deposit, and carries a higher cost to the operator and usually a tighter max-cashout cap. A deposit-match bonus is gated on a qualifying deposit and is the standard structure for most licensed offers.

How much wagering applies to a typical sign-up bonus under the UK’s current cap?

From 19 December 2025 wagering requirements on casino bonuses at GB-licensed operators are capped at 10x the bonus amount. A £100 bonus carries £1,000 of required wagering, which at a £5 stake-per-spin cap is 200 spins and at a £2 stake-per-spin cap is 500 spins.

Does a sign-up bonus expire if it is left unused?

Yes. Every licensed operator sets an expiry on its sign-up bonus, typically 30 days from credit for the bonus funds and 7 to 10 days for any attached free spins. The exact expiry is in the operator’s promotion terms and is not on the public register; it varies by brand and by promotion.

Can a sign-up bonus be claimed more than once on the same account?

No. A sign-up bonus is a new-customer offer and is claimable once per account per brand. Where two brands share a licence — Paddy Power and Betfair, Virgin Games and Jackpotjoy — a player who has claimed one brand’s sign-up offer is generally not eligible for the other brand’s offer on the same account under the same operator’s terms.
