A punter who has already signed up, deposited and placed a first bet does not disappear from a bookmaker’s commercial interest. They become the target of a different set of promotions: existing-customer offers, sometimes called loyalty offers or recurring promos, designed to keep a bankroll on this side of the fence rather than the next one. The terms attached to those offers, and the regulator’s new rules on what an offer may demand, decide whether any of them is worth chasing or whether the marketing only dresses up what an account is going to do anyway. This page works through what existing-customer and welcome promotions actually cost the customer under the Gambling Commission’s promotion rules in force since 19 January 2026, who the licensed operators are, and where on the comparison board each one sits.

Bonuses and free bets: what a promotion really buys the punter

Every offer attached to a deposit, a stake or a settled bet hides an arithmetic: required turnover, minimum odds, expiry, whether the stake comes back and which markets count. The Commission’s new rules reset the ceiling on how heavy that arithmetic can be, but they do not change the fact that an offer is an exchange, not a gift. A punter trades wagering work, stake risk and time for whatever the promo pays back.

The 10x wagering cap since 19 January 2026

From 19 January 2026 the Gambling Commission has capped wagering requirements on bonuses at 10x the bonus amount or the qualifying amount, whichever the operator’s terms state. Where the punter might once have been asked to turn a £10 bonus over fifty times in a punishing churn, no licensed bookmaker can now demand more than ten times the relevant figure. A £10 bonus with a 10x requirement means £100 of qualifying bets at the minimum odds before any of the bonus becomes withdrawable; the same bonus at the old 50x multiplier would have meant £500 of staking.

The cap is not a ceiling on bonuses themselves. Nothing in the rules stops a bookmaker from offering a large bonus in cash; what stops a bookmaker is the punishing turnover it could demand in return. Mixed-product promotions — an offer that asks the punter to bet on football to earn free spins, or to place an acca to unlock casino credit — are banned outright. A bonus sits inside one product at a licensed operator, and that single change ends a generation of cross-market promos that asked the punter to learn a casino lobby in order to drain a sportsbook bonus.

The Commission’s rules also leave a question open. Whether the 10x cap applies to free bets with no wagering condition at all — “bet credits” whose winnings are paid out as cash, where no further turnover is demanded — is not addressed by the published rules. Free-bet offers without a wagering term sit on a different legal frame, and a punter weighing one against another should read each bookmaker’s own terms rather than assume the cap catches both.

The vocabulary a punter meets before the maths

Four words govern the trade. A bonus is extra funds added to the account that must usually be wagered before they become withdrawable cash, with the original bonus amount often excluded from the eventual withdrawal. A free bet is a token to stake on a market where the stake itself is not returned with the winnings — a £10 free bet at odds of 4/1 (5.00) pays back £40 in profit only, not £50 in return. A price boost is an enhanced price on a named selection for a limited window: the punter stakes at the boosted odds, keeps the winnings in cash, and loses nothing if the bet loses. An acca insurance refunds a stake as a free bet when one leg of a multi-leg acca lets the rest down.

Each of these differs from the next in what happens when the bet wins and what happens when it loses. A bonus unlocks over time and cost a known turnover; a free bet pays only the profit; a price boost hands over the winnings outright; an acca insurance refunds the loss only when the terms are met. The shape of the offer shapes the arithmetic of whether to take it.

The lesson the maths teaches

A bookmaker sells margin on every market. The Commission caps how much extra margin an offer can demand in turnover, but the underlying margin inside each price is unchanged. A punter who runs through a bonus at minimum odds is paying the market’s margin on every rolled bet, which is the bookmaker’s normal profit; the bonus buys the punter exactly the value of those bets at a fair market, minus the bookmaker’s take. A punter who runs a free bet at long odds is paying nothing for the privilege but receiving nothing back if the bet loses. The trade, in every case, is identical: the punter takes the bookmaker’s margin in exchange for a chance of a payout the unrolled money would not have earned.

The punter who treats a promotion as a chance to get something free has read the page headline and stopped. The punter who treats it as an exchange they happen to be on the wrong side of has read further and is the one a serious bookmaker wants to avoid.

The comparison table: ten licensed brands and the licence behind each

Every brand on the table holds a Gambling Commission remote licence at the access date, verified against the Commission’s public register. The licence number and the named licensee are the test that the brand is regulated in Great Britain at all; everything below the licence line is the operator’s own statement of what its existing-customer or welcome promotion does. Several operators run under one licensee (Paddy Power and Betfair are the textbook pair), and the table treats each brand as the operator names it on the register rather than collapsing two entries into one.

The brands have different shapes. Coral and Sky Bet post welcome offers aimed squarely at first-time sign-ups with a tight minimum odds line and a short expiry; BetTom and 10bet advertise the largest headline bonus numbers but split the figure across sports and casino, which the Commission’s mixed-product ban now rules out where one offer asks for both. Kalooki Sportsbook and Copybet lean harder on existing-customer mechanics (boosts, acca boosters, extra places) than on welcome free bets; Sporting Index offers a hybrid that mixes fixed-odds and spread betting tokens, which a fixed-odds punter may find half-empty.

What the table cannot say

The punter looking at this list should not pick the largest bonus. They should pick the offer whose terms they can actually clear: a free bet whose minimum odds are lower than the price they actually bet at, with an expiry that fits how often they bet, and a stake-return rule that matches what the punter means when they say “free”. The Commission caps how punitive the turnover can get, but it does not cancel the fact that every bonus paid out is paid out of the bookmaker’s margin on the bets the punter must place to clear it.

Fundamentals of the UK betting market and the licence that underpins it

The starting point for any discussion of a UK bookmaker is the Commission licence. The Gambling Act 2005 is the foundation; the Gambling (Licensing and Advertising) Act 2014 made it point-of-consumption, meaning an operator whose remote facilities are used in Great Britain needs a Commission licence wherever it is based, including Curaçao, Malta, Gibraltar and the Isle of Man. A Curaçao, Maltese or Gibraltar licence is not a substitute. Section 33 of the 2005 Act, as amended, is the offence provision aimed at the operator, with punishments of up to 51 weeks’ imprisonment or a level-5 fine on summary conviction in England and Wales (six months in Scotland).

The licences themselves come in categories that matter for what a brand can offer. A remote general betting standard (real events) licence covers fixed-odds betting on actual sporting contests, which is what most punters mean by “betting”. A remote betting intermediary licence covers exchanges and the back-and-lay mechanic. A remote general betting standard (virtual events) licence covers simulated events generated by random number software, a separate product and a separate licence. There is no statutory cap on licences — the Commission has issued them to many hundreds of brands — and no state monopoly; ten brands reviewed here is a thin slice of a market that runs into the hundreds.

What the licence does, in practice, is pin the operator to a rulebook, the Licence Conditions and Codes of Practice (LCCP). The LCCP sets the safer-gambling duties, the anti-money-laundering obligations and the bonus restrictions discussed below. It does not set the markets or the odds; an operator chooses which sports to take bets on and at what prices, subject to its own commercial judgement and the LCCP’s broader duties on consumer protection.

Verification, age and what a licensed account does

Since 7 May 2019 a licensed remote bookmaker has had to verify name, address and date of birth before a customer can deposit or gamble, including with a free bet or bonus. The verification happens against public records and is not optional; a punter who does not pass it cannot place a bet. The minimum age is 18, and the rule applies whether the customer uses a credit-card-funded e-wallet or pays from a debit card. Identity verification is the difference between a licensed operator and an offshore one, and it is also the price of every licensed market the punter gains access to.

What may be bet on

No statutory list of permitted bets or markets exists. An operator holds a licence for a category and offers markets under its own rules and the LCCP. In-play betting is offered by most licensed bookmakers and is governed by the operator’s licence conditions and customer-protection duties; an analysis cannot write that in-play is “unrestricted” as a legal conclusion, because the controls vary by operator and by market. Esports are treated like any other sporting event. Virtual events are a separate licence category. Bets on politics, TV shows and novelty markets are offered by some licensed operators and are not prohibited by statute.

One-off events, what the betting vocabulary calls “ante-post” on horse racing months ahead of a meeting, sit inside the same licence category. The Rule 4 deduction, where a non-runner forces a reduction of the odds on the runners that remain, is a bookmaker rule, not a statutory one. Spread betting on sports that is not a financial instrument sits inside General Betting Duty; financial spread betting is regulated by the Financial Conduct Authority and not by the Commission at all.

The legal frame in force at the time of writing

The Commission’s promotion rules of 19 January 2026 are the headline change. Wagering requirements on bonuses are capped at 10x, and mixed-product promotions are banned. A punter betting £10 to claim £40 in free bets at a brand whose welcome offer is “bet £20, get £40” needs to clear turnover of £80 on the bonus side before any of it is cash; the same offer a year ago might have asked for turnover several times that figure.

The second strand is GAMSTOP. Every GB-licensed remote operator signs up to the national multi-operator self-exclusion scheme, which lets a punter bar themselves from every licensed account for six months, one year, five years or five years with auto-renewal, and which stays in place for a further seven years after the minimum period ends unless the punter asks GAMSTOP to remove it. GAMSTOP covers online sites and apps; betting shops use a separate service. An offshore operator has no obligation to honour the GAMSTOP bar at all.

The third strand is the financial-vulnerability check in force from 30 August 2024 (LCCP condition 3.4.4). When a customer’s deposits minus withdrawals cross £150 in a rolling 30 days, with the threshold taking effect from 28 February 2025, the operator runs a public-record check (bankruptcy, county court judgments and the like), not an income check and not a credit reference check. The purpose is to flag a customer in financial difficulty without invading the customer’s privacy. Financial risk assessments, the affordability checks of the press, were announced in a Commission article of 7 July 2026 and run on a staged plan with no start date, so the present tense is “announced” and nothing stronger.

The fourth strand is the marketing code. The CAP Code (non-broadcast) and BCAP Code (broadcast) are enforced by the Advertising Standards Authority. Section 16 of the CAP Code requires marketing to be socially responsible, not of strong appeal to under-18s, and not to feature anyone who is or appears to be under 25 gambling or playing a significant role, with an exception for marketing placed where a bet can be made directly (the betting shop front window, an in-app splash). The rule is about who appears in an advertisement, not who can place a bet. The “whistle-to-whistle” rule, no betting ads on TV five minutes before a live sporting event to five minutes after, with horse and greyhound racing excepted and a 9pm watershed, is an industry code rather than a statute; it has run since 1 August 2019. Operators are responsible for marketing run by their affiliates, and the licensed brand behind the ad cannot hide behind an agency when a complaint is upheld.

The fifth strand is credit. Credit cards have been banned for gambling in Great Britain since 14 April 2020 (LCCP condition 6.1.2), including credit-card-funded payments through an e-wallet; debit cards and bank-based payments are not covered by that ban. A punter who pays by credit card at an unlicensed site does so outside the rule, but also outside the protection.

Tax in Great Britain

The player pays no tax on betting winnings. That is general information, not tax advice, and a professional gambler should ask HMRC or an adviser; the casual punter does not need to set aside a slice of any payout. General Betting Duty is the operator’s tax on gross profits and sits at 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-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 carries its own rates: 3% on financial spread bets and 10% on other spread bets. The Commission’s statutory levy is a separate charge, not a tax. Whether operators pass duty on through their odds is unclear; a punt at lower odds is not a charge that can be called “duty”.

What offshore means in practice

A GB licence is compulsory at the point of consumption. The punter who bets with an unlicensed offshore brand loses none of the action but loses the protection the licence gives. There is no GAMSTOP coverage; the £150 vulnerability check, the 10x bonus cap, the LCCP customer-protection duties and the Commission’s complaints route do not bind the operator at all. Where the operator withholds funds in a dispute, the punter has no British consumer redress. Section 33 of the Gambling Act 2005 punishes the operator, not the punter, for providing unlicensed gambling facilities; a customer who bets on an unlicensed site is not committing a known offence, and writing that the offshore site is “legal to use” would not match what the rules actually do. The honest framing is the one an experienced punter recognises: licensed means checks, limits, GAMSTOP and the bonus cap; unlicensed means none of those, and a real chance of losing funds that the punter cannot retrieve.

Responsible gambling and the rules under which a licensee’s offer stands

Every brand reviewed on this page is bound by the same safer-gambling code, which is worth reading on its own terms because it is the rule that catches every offer in the long run.

Identity and age verification are the entry condition. No licensed brand lets a punter deposit, bet or even claim a free bet without a verified name, address and date of birth. The verification happens against public records and can ask for documents; a punter who refuses cannot use the site. The rule exists because a licensed operator cannot legally let an under-18 stake funds, and because a licensed operator needs to know who it is paying out to in the event of a dispute.

GAMSTOP is the second line. A punter who has excluded themselves through GAMSTOP cannot open an account, and a punter who opens an account first and excludes themselves later has the account closed. The exclusion period is six months, one year, five years or five years with auto-renewal; after the minimum period, GAMSTOP keeps the exclusion in place for seven more years unless the punter asks for it to come down. The scheme covers online sites and apps; a punter who still wants to bet in a shop needs to register separately there.

Deposit and stake limits are the customer’s tools. Operators must offer a gross deposit limit (RTS 12), with the first changes live since 31 October 2025 and a second phase postponed to 30 September 2026; whether that second phase is now live is not established, and a punter should check the operator’s own limit page rather than assume a uniform ceiling. Limits are the customer’s choice — there is no state-set ceiling — and setting one is a matter of seconds on most licensed accounts. Time-out, reality checks and product-level blocking sit alongside deposit limits in the safer-gambling menu.

The financial vulnerability check is the new layer. From 30 August 2024, with the £150 rolling-30-day deposits-minus-withdrawals threshold applying from 28 February 2025, an operator runs a public-record check on customers whose spend crosses the line. The check looks at bankruptcy and county court judgments and the like, not at income and not at credit files. The check is to flag a customer who is in financial difficulty without forcing them to share earnings or outgoings.

Where to get help. GamCare runs the National Gambling Helpline and the network of counsellors; GambleAware funds treatment and research; NHS gambling clinics run in-person and remote treatment; Gamblers Anonymous runs peer-support meetings across the country. The Commission’s website lists the codes of practice and the register of licensees; a punter who wants to know whether a brand is licensed can find out on the public register and read the conditions it operates under.

The same framework applies to the offers in the comparison table. No promotion is allowed to ask the punter to gamble on two or more product types; no bonus can demand more than 10x turnover; no credit card is allowed; no under-18 stake is allowed. The brand’s offer sits inside the code, and the code is what catches the offer when it tries to demand more.

BetTom: a half-and-half package against a strict new rule

BetTom’s welcome package splits 50% back as a free bet up to £50 on the sports side, matched by 50% back as free slot funds up to £50 on the casino side, with full terms applying on each side. The headline is generous against the licensed set. The brand’s operator, Bet Tom Limited, holds Gambling Commission remote licence 064959-R-339314-003 (account 64959) for remote general betting standard (real events).

The shape of the offer matters more than the headline. From 19 January 2026 the Commission’s mixed-product promotion ban rules out an offer that asks the punter to gamble on two product types. BetTom’s terms keep the sports and casino sides as separate promotions rather than a single gate, which lets the brand carry a casino bonus alongside a sports bonus without breaching the rule; a punter who claims only the sports side is doing what the rule allows, and the bundled reading is exactly the one the rule prohibits. A punter who wants the sports book offer needs to read the terms closely and not assume the headline settles the choice.

The licence is the cleanest part of the picture. BetTom Limited is a UK-incorporated company; the licence is a remote general betting standard (real events) licence, which covers everything a sportsbook does; there is no liability hedging to the kind of operator that hides behind an offshore parent. The verdict on BetTom depends on what the punter is willing to do: a casual sportsbook bettor who never sees the casino lobby has nothing to lose by taking the half-and-half offer and ignoring the casino side, while a punter who plays both is being asked to read two sets of terms at once. The brand is for the punter who treats the sports side as the only deal in town and ignores the rest.

Coral: a 7-day welcome and a heavier existing-customer side

Coral’s welcome is “Get £40 in Free Bets when you bet £20”: a deposit and sports bet of £20 or more at minimum odds of 2.0 (1/1), with the free bets issued within 7 days and expiring 7 days after issue, for new GB customers who opt in. The brand operates under LC International Limited, which holds Gambling Commission remote licence 054743-R-330863-014 (account 54743). This licence, covering the brand’s full range of products, is part of the larger Ladbrokes Coral plc (now Entain plc) group’s portfolio.

The existing-customer product is where Coral does most of its work. A free daily Reward Shaker turns a settled bet into a randomised prize draw; an Odds Booster sits on hundreds of markets; free-to-play games such as Football Super Series carry a £10,000 jackpot. Coral is not betting its commercial future on the welcome free bets, and the recurring product is the section of the offer book a long-time customer actually meets.

The minimum-odds line of 2.0 is the practical clause. A punter who would back favourites at 4/6 cannot use this offer without nudging up their price; a punter whose normal bet is at evens or longer has to push their usual stake from £20 to £20.01 to clear the qualifier, which is the kind of behavioural nudge the Commission’s terms prohibit in spirit even when they pass the letter. The expiry is tight, with both the issue window and the redemption window capped at 7 days, which fits a punter who bets every weekend and excludes the casual monthly bettor. Coral is for the punter whose existing-customer mechanics matter as much as the welcome, and whose bankroll runs to qualifying bets inside a week rather than a month.

Dabble: a tight welcome with a stake that does not come back

Dabble’s offer is “Bet £10, Get £10 in Free Bets” on a first deposit, with minimum odds applying, a 7-day free bet expiry and the free-bet stake not returned on a winning free bet. The brand is licensed under Commission remote licence 065677-R-340363-005 (Commission account 65677), with the licence held by Dabble Sports UK Ltd, a UK company. The category on the register is “remote general betting standard (real events)”.

The shape of the offer is the smallest one in the comparison. A £10 bet returns £10 in free bets that themselves expire in a week and do not return the stake, and the free-bet arithmetic on this size of token is the kind of long-shot punter punt about it is. The maths works as follows. A £10 free bet at minimum odds of 1/2 (1.5) returns £15 in profit if it wins, of which £0 is returned stake, and the punter’s cost is the £10 stake on the qualifying bet. A punter who clears a £10 free bet at 1/2 is paying for a token they would have staked anyway; a punter who backs a 4/1 outsider on the free bet returns £40 profit on £10 staked with the bookmaker and zero further risk, which is the arithmetic the offer wants the punter to find.

Dabble’s product is social. The brand pitches itself on social-betting mechanics that allow customers to copy each other’s bets; the offer sits alongside that as the welcome gift, not the centre of the experience. The verdict on Dabble is straightforward: it is for the punter who would have used the app for the social feed anyway and gets £10 in free bets as a side benefit, not for the punter whose reason to download is a £10 free bet alone.

Sky Bet: a £30 welcome for a small first stake

Sky Bet’s new-customer offer is £30 in free bets, credited as three £10 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 brand’s licensee, SBG Sports Limited, holds Gambling Commission remote licence 067370-R-341330-005 (account 67370) for remote general betting standard (real events). Sky Bet operates alongside Sky Casino and Sky Bingo under this shared licence.

The minimum-bet qualifier is the smallest in the comparison. A punter who deposits £5 can place a 5p bet at 1/1 and unlock the £30 free-bet package, which makes Sky Bet’s offer accessible in a way the others are not. The condition reads, on its face, as a gift: a 5p bet is a negligible risk, and the £30 in free bets covers the cost of it many times over. The arithmetic kicks in once the free bets are placed. Three £10 free bets whose stake is not returned on a win give a punter earning at minimum odds of 1/2 (1.5) a return of £15 profit per token, with the £10 stake at risk; at 4/1 the return is £40 profit per token on a token that cost the punter nothing. The expiries of Sky Bet free bets are short, and a punter who treats the offer as a long-term stash will lose the tokens before they place them.

The verdict on Sky Bet is that the offer is genuine, and the price of accessing it is a 5p bet that the punter would have placed on the same event anyway. The free bets are for the punter who can run three £10 stakes inside the expiry window and is comfortable betting at 1/2 or longer.

Kalooki Sportsbook: smaller brand, instant-withdrawal headline

Kalooki Sportsbook offers instant withdrawals by bank transfer within minutes, Best Odds Guaranteed on UK and Irish horse racing, in-play betting, daily boosts and extra place races. The brand’s operator, Kalooki Sportsbook Limited (UK company 12938274), holds Gambling Commission remote licence 057730-R-333396-005 (account 57730) for remote general betting standard (real events). The brand is a GAMSTOP member.

This is a smaller brand than Coral or Sky Bet. There is no welcome free-bet package — the brand pitches on the existing-customer mechanics rather than the welcome offer. A punter who reaches Kalooki’s site is being pitched the daily boosts and the horse-racing Best Odds Guaranteed, not a headline free bet. The instant-withdrawal line is the strongest differentiator, and what a punter who wants the funds in their account tonight would look at first.

The verdict on Kalooki is that it is a smaller-brand pick for the punter who has decided that fast withdrawals and Best Odds Guaranteed matter more than the headline welcome free bet. A punter whose main concern is the welcome offer will find ten better-known competitors offering more on the surface; a punter whose main concern is the day-to-day experience on the racing side finds Kalooki’s product honest and the licence clean.

Sporting Index: a fixed-odds and spread-betting hybrid

Sporting Index’s new-customer offer is a hybrid: a £10 fixed-odds bet at minimum odds of 1/2 unlocks three £10 fixed-odds free bets, three £5 Total Goals spread bets, three £5 Winning Favourites spread bets and a £1 Race Index spread bet, and the qualifying bet cannot be placed in play or cashed out early. The brand’s operator, Sporting Index Limited, holds Gambling Commission remote licence 027343-R-308898-011 (account 27343).

This is the only hybrid offer in the comparison. A punter who has never placed a spread bet will meet one at the betting-slips page, where the Total Goals spread and Winning Favourites spread are token trades rather than real stakes. The qualifying bet is a normal fixed-odds bet, and the offer is built to land that punter into Sporting Index’s main spread product. Spread betting is a different mechanic from fixed odds: a stake is sized against a range (Total Goals, say, 2.5 to 3.0 in a football match), the punter’s profit or loss depends on where the outcome lands inside the range, and a stake can produce a result larger than its face value in both directions.

The verdict on Sporting Index is that the offer is a way into spread betting for the curious and a small fixed-odds welcome for the rest. The free fixed-odds tokens are usable like any other; the spread tokens are a sample of the spread product; a punter whose interest is purely in fixed odds gets three £10 free bets to use and a small introduction to a different market.

Copybet: acca mechanics for the existing customer

Copybet’s main offer book leans on acca mechanics. The Acca Booster pays up to a 100% cash bonus on accas of at least 3 selections, and the Daily Profit Boost pays up to 15% on selected markets. Copybet UK Limited holds Gambling Commission remote licence 053774-R-330743-010 (account 53774) for remote general betting standard (real events). There is no welcome free bet; the brand pitches its existing-customer product as the proposition.

The acca shape explains the brand. Copybet’s wider product is a copy-trading service where customers can copy each other’s accas; the offer book lives in the same space. An acca punter who runs 3-folds and bigger will see a 100% boost when the ticket wins, paid in cash, and the boost rises with the number of legs (the source caps at 100% but does not give the full scale). A Daily Profit Boost adds a further 15% on markets the brand chooses.

The verdict on Copybet is that it is for the acca punter who runs 3-leg and bigger tickets most weeks. A punter who bets singles will find nothing here; a punter who bets 2-folds will find the Acca Booster not yet active; a punter whose acca habit is the centre of their betting will find the existing-customer product worth reading.

QuinnBet: tight minimum odds, restricted bet types

QuinnBet’s free bets are valid for 7 days from credit and can be used on any market at odds of 1/2 (1.5) or greater, with maximum odds of 50/1, and straight accumulators are allowed while Trixies, Patents and Yankees are not. QuinnBet (Gibraltar) Limited holds Gambling Commission remote licence 061011-R-335683-004 (account 61011) for remote general betting standard (real events).

The terms detail is the brand’s signature. Most acca-and-multi-bet brands allow Trixies and Patents; QuinnBet’s exclusion cuts the multiple-bet repertoire down to straight accumulators, which reduces the punter’s design choices in return for a clearer promotion. The max-odds of 50/1 is the practical limit: a free bet backed at higher odds would not be paid, and a punter running long-shots needs to stay inside the cap. The 7-day expiry is the standard length.

The verdict on QuinnBet is that the brand is for the punter who runs single-leg bets and straight accumulators at 1/2 to 50/1 odds and is comfortable without a multiple-bet structure. A Trixie-and-Patent punter would feel the exclusion at the betting slip; a punter who runs singles and 4-folds would not.

10bet: the headline figure and what the brand really does

10bet advertises a 100% up to £50 betting bonus for UK sign-ups, plus daily free bets and free spins. The brand’s licensee, Blue Star Planet Limited, holds Gambling Commission remote licence 043173-R-322899-023 (account 43173) for remote general betting standard (real events).

The headline is the largest in the comparison. A 100% match up to £50 means a £50 deposit earns £50 in bonus, before any turnover is taken into account. The mixed-product reading — daily free bets on the sports side and free spins on the casino side — sits alongside the 19 January 2026 ban on offers that ask the punter to gamble across two product types; the brand carries daily free bets and free spins separately rather than gating one behind the other, and a punter who claims only the sports bonus meets the rule on its own terms.

The verdict on 10bet is that the brand is for the punter who wants a large welcome bonus and is willing to read the turnover terms carefully. A punter who treats the £50 as free and ignores the wagering will hand it back to the bookmaker; a punter who reads the bonus terms finds a 10x cap (the Commission’s ceiling) and a chance to clear the bonus at minimum odds inside the expiry.

Smarkets and SBK: an exchange’s sportsbook arm

Smarkets operates the SBK sportsbook, whose UK welcome offer is a £20 first deposit and £20 bet at minimum odds of 3.0 for £60 in free bets within 48 hours, with Cash Out, Bet Builder and live horse racing streams. The combined brand is fully licensed under Commission remote licence 039173-R-319366-011 (Commission account 39173), with the licence held by Smarkets (Malta) Limited. The category is “remote betting intermediary”, which is the exchange licence rather than the standard sportsbook licence, and the SBK sportsbook operates under the same umbrella.

The 3.0 minimum qualifier is the strongest in the comparison. Most welcome offers demand 1/1 or longer; SBK asks for 3.0, and a punter who cannot find a 3.0 selection has no qualifying bet. The reward matches the demand: a £20 qualifying bet at 3.0 unlocks £60 in free bets, which is the largest welcome offer relative to the stake in the comparison. The 48-hour credit is short — Coral’s window is 7 days and Sky Bet’s is longer — and a punter whose account is light on cash flow may not see the £60 before the bonus terms tighten around it.

The verdict on Smarkets’ SBK is that the offer is for the punter who can find a 3.0 qualifying bet comfortably and wants £60 in free bets in return. A punter whose natural market sits below 3.0 will not be able to use the offer without changing their bet; a punter whose betting slip often carries a 3/1 outsider will hit the qualifier without effort. Smarkets’ wider product is an exchange, which the punter on this page is meeting as the surface for SBK’s sportsbook.

How heavy an offer is, in clear terms

What follows is one calculation: the bonus-turnover arithmetic, with the offer terms in and the 10x wagering cap in force since 19 January 2026. The example is the Coral welcome offer — a £20 qualifying bet at minimum odds of 2.0 (1/1) returning £40 in free bets whose stake is not returned on a win, with the free bets issued within 7 days and expiring 7 days after issue. The wagering condition sits in front of any portion of the offer that the punter can convert to cash, where the brand requires one; on Coral’s headline, the £20 stake on the qualifier is the punter’s cost and the £40 in free bets is paid out in token form that can be staked but cannot be added to a cash balance until a turnover has been cleared.

The arithmetic, in bands. A bonus where the base is the £20 qualifying stake and the wagering multiple is 10x (the Commission’s cap) gives required turnover of £200 (10 × £20). At a £20 stake per qualifying bet, that is 10 bets; at a £10 stake, 20 bets; at a £5 stake, 40 bets. Each bet must be at minimum odds of 2.0 (1/1), at decimal odds of 2.00 or longer, and the punter’s market-margin cost is whatever the bookmaker’s normal margin on the chosen market produces. A punter running this turnover at minimum odds pays the bookmaker’s margin on every rolled bet, with the bonus and free bets paid out of that margin rather than added on top.

The result, stated as a band rather than a figure. At a bookmaker margin of around 5% on a typical football match, the punter’s expected cost of clearing the £200 turnover is in the region of £10 (5% of £200); at a margin closer to 8% on a tighter market, the cost moves toward £16 (8% of £200). The £40 in free bets that issued the work is paid out in token form, with the stake not returned on a win, and a punter running the free bets at 1/1 minimum odds (1.5) sees them pay back a profit band of £20 to £60 on a £40 total stake depending on price. The cost clears a portion of the offer; the remainder depends on how the punter runs the free bets and which markets they choose.

The conclusion is the one the formula admits: the offer is an exchange in which the punter takes the bookmaker’s margin in exchange for a chance of free-bet profit. At the worst case, the punter loses the £20 qualifying stake and gains nothing; at the best case, the punter realises close to the headline value of the free bets. The Commission’s 10x cap rules out the bottom of the old range, where wagering could demand several times the bonus, but it does not turn the offer from a trade into a gift.

The verification a punter should run before any deposit

The first action is the register search. The Commission’s public register is searchable by business name, trading name, domain or Commission account number. Every brand on this page is verifiable on the register, and the licence number beside the brand is the one to use. A brand that does not appear on the register is unregulated in Great Britain, and the consequences of betting with an unregulated brand run from the immediate (no GAMSTOP coverage, no vulnerability check at the £150 threshold) to the eventual (no British complaints route if funds are withheld).

The second action is reading the terms behind the offer. A 100% bonus up to a large number looks attractive; the wagering factor, the minimum odds, the expiry and the stake-return rule decide what the bonus actually pays out. The Commission’s 10x cap rules out the punishing turnover of the old market, but the rest of the terms — minimum odds, expiry, market restrictions, cap on free-bet winnings — sit on each operator’s own page and are not standardised across brands.

The third action is the safer-gambling menu. A licensed operator offers deposit limits, time-outs, reality checks and GAMSTOP exclusion, and these are the tools a punter uses to keep their bookmaker book in proportion to the wallet. Setting a deposit limit on day one is cheaper than asking GAMSTOP to take an account down six months later. The Commission’s framework — checks, limits, GAMSTOP, the 10x cap, the mixed-product ban — is the frame a licensed brand cannot avoid, and it is also the frame a punter should expect when they sign up.

A punter who keeps the register in front of them and the terms beside them is the punter who treats a promotion as a trade rather than a gift, and that is the only kind of punter who comes out of the table at the top of this page with something to show for it.

Frequently asked questions about existing-customer betting offers in Great Britain

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

From 19 January 2026 the Gambling Commission caps wagering requirements on bonuses at 10x the bonus or qualifying amount — a £10 bonus at 50x (which would have meant £500 of bets before the change) cannot now demand more than £100 of turnover. The cap applies to bonuses, and whether it covers free bets with no wagering condition has not been settled by the Commission’s published guidance at the time of writing; each operator’s own terms are the place to check whether a given offer carries a wagering condition at all.

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

Minimum odds are the shortest price (closest to evens) at which a qualifying bet or a turnover bet must be placed; Coral’s welcome offer requires 2.0 (1/1), and a punt on anything shorter does not count toward the offer. The wagering requirement is how many times the bonus or qualifying amount must be staked before any of it can be withdrawn as cash — a 10x requirement on £20 means £200 of qualifying bets before the bonus pays out in cash terms, with the Commission’s 10x cap now setting the ceiling.

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

The Commission’s rules treat a free bet as a token whose stake is not at the punter’s risk, so a £10 free bet at 4/1 pays back £40 in profit rather than £50 (stake + profit). The same logic underlies minimum odds and maximum winnings caps on free bets: the token is the bookmaker’s contribution, and what is paid out is the profit on that contribution. A punter who would stake the same bet from cash finds the winnings 20% to 50% smaller when funded from a free bet, and that is the trade the offer is built around.

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

No. From 19 January 2026 the Commission has banned mixed-product promotions — offers that ask the punter to gamble on two or more product types, such as a free-bet offer whose clearing requires casino play, or a sportsbook welcome that unlocks casino credit. Where a brand offers both products, the offers have to run as two separate promotions rather than one gated bonus; BetTom and 10bet both advertise sports-plus-casino bundles, and a punter should read the terms to confirm the two sides are independent rather than cross-gated.

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

The Commission’s public register at its official site is searchable by business name, trading name, domain or Commission account number, and the brand-and-account-number pair is the whole test. A licensed brand appears in the category that covers the product it offers (remote general betting standard for sportsbooks, remote betting intermediary for exchanges). A brand that does not appear is unregulated in Great Britain, and the protections the licence brings — GAMSTOP coverage, vulnerability checks, 10x bonus cap, British complaints route — do not apply.

Are betting winnings taxed in Great Britain, and who pays General Betting Duty?

The player pays no tax on betting winnings in Great Britain — that is the basic position, though a professional gambler should ask HMRC or a tax adviser. General Betting Duty is the operator’s tax on gross profits, currently 15% with a new remote rate of 25% applying from 1 April 2027 inside it; whether operators pass duty through into their odds is not established, and the punter is not charged duty on top of any losing stake. Spread betting carries its own rates: 3% on financial spread bets and 10% on other spread bets, levied on the operator.
