Last verified against the Gambling Commission’s public register and each operator’s own terms on 27 October 2026. The wagering cap and the ban on mixed-product promotions are checked against the Licence Conditions and Codes of Practice in force since 19 January 2026.

An “enhanced odds” offer looks like a free lunch on a Saturday afternoon. The bookmaker agrees to pay a bigger price on a chosen outcome than its own trading screen shows, hands a new customer a free bet as a welcome, or boosts an acca by a percentage. The mechanism is simple; the cost lives in the small print, and in Great Britain the small print now lives inside a new rulebook. Since 19 January 2026 the Gambling Commission has capped wagering requirements on bonuses at ten times, and it has banned the old “bet on football, get free spins” marketing trick that strapped a casino bonus to a sports sign-up. What the rules do not change is the arithmetic of a free bet: the stake is usually not returned, the minimum odds and the deadline still bite, and a price boost is still a one-shot bet on the bookmaker’s own selection list.

This page works through ten UK-licensed bookmakers on what each one offers, what the terms actually require, and what kind of bettor each one suits. The aim is the choice: not a verdict on which is “best”, but a clean read of which paths exist and who each one suits — a small-stake bettor who wants a free bet, an acca player chasing percentage boosts, a spread bettor who wants price insurance, and everyone in between. The legal frame, the responsibility tools and the offshore warning all sit before the ranked review, because every decision below assumes the reader knows the rules in which these offers are made.

Responsible gambling in Great Britain: the safety net every review on this page assumes

Every bookmaker on this page holds a Gambling Commission remote licence. That licence is not a marketing badge; it carries a set of obligations that shape what the operator can and cannot do, and the first of those obligations is to look after the customer. Before weighing welcome offers and price boosts it is worth being clear about the safety net, because a “good deal” stops being good the moment a stake gets out of hand.

GAMSTOP is the national multi-operator online self-exclusion scheme. Every GB-licensed remote operator is required to take part, which means a single registration closes online play across every brand reviewed below for the chosen period. The minimum exclusion is six months, then one year, then five years; the longest is five years with auto-renewal. After the minimum period the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it. The scheme covers online sites and apps. High-street betting shops run a separate in-shop self-exclusion, which a GAMSTOP registration does not cover.

Financial vulnerability checks are a Commission rule that bites more quietly. Since 30 August 2024 a licensed remote operator has been required to run a public-record check — bankruptcy registers, county court judgments and the like — when a customer’s deposits minus withdrawals clear £150 in any rolling 30 days (the threshold has applied since 28 February 2025). The check is a public-record check, not an income check and not a credit reference check, and it is not the same thing as the more onerous “financial risk assessment” the press usually calls affordability checks. Those fuller assessments were announced in a Commission article of 7 July 2026, in a staged plan with no start date as of the date this page was checked.

Deposit limits are a customer-set tool that every licensed operator must offer. The first round of changes to the technical standard applied on 31 October 2025, and a second phase was scheduled for 30 September 2026. Whether that second phase is live as of today was not established in the register. Limits remain the customer’s choice; no state-set ceiling for betting exists. Some operators go further: DAZN Bet documents deposit, loss and wagering limits in its safer-gambling toolset, which is a useful reference point if a reader wants to see what a structured limit panel actually looks like in an account.

Identity verification happens before the first deposit, has done so since 7 May 2019, and applies to free bets and bonuses, not only to real-money play. Midnite, for example, cites its Commission licence and runs the same check on anyone who signs up; Betmaster, Coral and Unibet run comparable flows. The flip side is that no anonymous play is possible at a licensed site, and the bettor’s first move after sign-up is to satisfy the verification, not to grab a free bet.

Help is reachable independent of the bookmaker. GamCare runs the National Gambling Helpline. GambleAware funds treatment and education. The NHS runs gambling clinics in several regions. Gamblers Anonymous runs group meetings. The links sit on every licensed operator’s safer-gambling page — Betfred’s app lists responsible gambling information and GambleAware contacts alongside its free-bet promotions, which is the layout a careful bookie presents: the offer, then the help, in that order.

The point of this section is not to lecture but to set the floor. A reader who wants a £40 free bet has, at every brand reviewed below, a Commission licence, a GAMSTOP opt-out, a deposit limit panel and a public-record vulnerability check on the other side of the welcome screen. The offer sits on top of those; the offer is not a substitute.

Bonuses, free bets and price boosts: how a “free” bet is actually priced

Marketing has its own vocabulary, and almost every word in it is a small lie the page is meant to be honest about. A “free bet” is a credit with a price. A “risk-free” bet is usually a free bet that refunds the stake as a free bet if the first bet loses — that is, “risk-free” in marketing, but with the refund taken as another free bet rather than cash. A “price boost” is a one-shot enhancement on a chosen outcome. An “acca insurance” refunds a stake as a free bet if one leg of an accumulator lets the rest down. Each of these is a defined product with a defined cost, and the cost lives in four places.

The first is the qualifying bet. A welcome offer usually requires a first real-money bet at or above a minimum stake, at or above minimum odds, on a chosen market type, and paid by a chosen payment method. Coral’s sports welcome is “Get £40 in Free Bets when you bet £20”: the £20 must be placed at minimum odds of 2.0 (1/1), paid by a debit card or instant bank transfer, and the bet settles the offer. Unibet’s sports welcome is the same headline — £40 in free bets for a £20 qualifying bet at minimum odds of 2.0 — and it also names the qualifying payment methods. Spreadex’s new-customer offer is £60 in free bets for a £10 fixed-odds bet placed within 28 days of account opening, at minimum odds of 1/2. Each of these looks generous until the qualifying bet is read against the same market without the offer attached, at which point the £20 is a real-money bet at 1/1 minimum that may not have been the bet the customer would otherwise have placed.

The second is the minimum odds on the free bet itself. Where the offer states a minimum odds on the qualifying bet, it usually states one on the free bet too — sometimes the same threshold, sometimes a tighter one. QuinnBet’s free bets, for example, are usable on any market at odds of 1/2 (1.5) or greater, with a maximum odds of 50/1, and exclude combination bets of the kind that would let the customer use the free bet on a long-priced acca. BoyleSports’ Acca Insurance carries a 1/2 minimum-odds line on every leg of the qualifying acca. The rule of thumb is that the lower the minimum odds, the more freedom the free bet has; the higher the minimum odds, the more the bookmaker is steering the customer toward a market the bookmaker’s margin already favours.

The third is the deadline. Coral’s £40 in free bets is issued within seven days of the qualifying bet settling, and the free bets expire seven days after they are issued. Spreadex’s £60 in free bets is usable across fixed odds and spread betting but the qualifying bet must be placed within 28 days. BoyleSports’ Acca Insurance pays a free bet that expires in seven days; BoyleSports’ Acca Loyalty free bet expires after seven days. QuinnBet’s free bets are valid for seven days from credit. The deadlines cluster around a week, which is short enough that the customer has to plan around them rather than wait for a fixture list to refresh.

The fourth is the stake treatment on a winning free bet. In Great Britain, the free-bet stake is typically excluded from returns: for instance, a £10 wager at 3.0 odds generates £20 in profit, rather than a £30 total return. A handful of offers change that, and the change is always stated in the small print. It is worth treating “stake not returned” as the baseline and reading any deviation from it as the operator’s concession rather than as the industry standard.

On top of all four comes the wagering requirement. This is the rule that has just been changed. From 19 January 2026 the Commission’s promotion rules cap wagering requirements on bonuses at ten times the bonus amount: a £10 bonus with a 50x requirement needed £500 of qualifying bets to clear; the cap means no licensed bonus can demand more than ten times its face value in betting volume. The same rules ban mixed-product promotions — an offer that requires gambling on two or more product types such as betting, casino, bingo and lottery. An offer where a customer must bet on one product to claim a bonus on another is the kind of welcome the new rules catch. Whether the cap applies to free bets that carry no wagering condition at all is not established in the rules as published. The second related figure is the one to watch: the Commission’s first phase of deposit-limit changes was already in force on 31 October 2025, and a second phase was scheduled for 30 September 2026, with live status not established in the register snapshot this page works from.

A worked example makes the difference the new cap makes. Take a hypothetical £20 bonus with a 6x wagering requirement and a 1/2 minimum-odds rule on the qualifying bets, ignoring expiry for a moment. The required turnover is £20 multiplied by 6, which is £120 of qualifying bets. At a stake of £10 per bet, that is twelve bets to clear the offer. At a stake of £5, it is twenty-four. The pre-cap ceiling for a £20 bonus at the old extreme would have been 50x, which is £1,000 of qualifying bets — the kind of requirement that turned a bonus into a treadmill. The 10x cap does not make bonuses free; it puts a roof on how heavy the treadmill can be. The same arithmetic for Coral’s actual welcome offer — a £20 qualifying bet producing £40 in free bets — is different in kind, because Coral’s offer is a free bet rather than a bonus with a wagering requirement, and the wagering cap does not apply to free bets in the same way it applies to bonuses that have to be turned over before withdrawal. The headline still needs to be read against the small print.

A worked turnover at Coral’s qualifying terms, to fix the shape of the new rule in a real product: the £20 qualifying bet at minimum odds of 2.0 produces £40 in free bets, which the customer uses on markets at or above the bookmaker’s free-bet minimum. If the £40 in free bets carried a hypothetical 5x wagering requirement (none is published for the Coral offer at the snapshot date), the customer would need £200 of additional qualifying bets to release any winnings as cash. The headline’s £40 in free bets becomes £40 of credit to bet with, on a clock, with the same minimum-odds rule attached. The 10x cap is what stops a bonus from asking for a turnover five times heavier than this; that is the change worth knowing about before reading the welcome headline.

The market for a price boost is a different question. A price boost is not a bonus. It is a higher price than the bookmaker’s own trading screen would otherwise show, applied to a chosen outcome, and it is paid in real money if the bet wins. Kwiff’s Supercharge feature, for example, can boost the odds on a bet from 2/1 to 20/1 on a single bet, on any sport, and on singles or multis. bet365 runs Super Boosts and daily Bet Boosts, plus Winnings Boosts on Bet Builders and selected singles. Coral runs an Odds Booster on hundreds of markets. William Hill runs a Football Acca Boost on accumulators of two or more legs at 1/5 or bigger per leg, with a boost from 3 % on a double up to 200 % on twenty or more legs, capped at £10,000 per online bet, running until 30 May 2027. The cost of a price boost is paid out of the bookmaker’s margin, not out of the customer’s deposit. The customer is not being asked to turnover; the customer is being asked to bet on a market the bookmaker has already chosen, with a stake ceiling that is usually lower than the same market’s ordinary ceiling.

The honest summary is that “enhanced odds” and “free bets” and “boosted accas” are three different products with three different cost structures. The first is paid in margin, the second is paid in qualifying bets and expiry, the third is paid in the acca’s own risk. A reader who treats the three as one is the reader an offer is written for; a reader who keeps them separate is the reader an offer has to satisfy on its own terms.

How the ten sites were chosen and what the comparison actually shows

The brands on this page are not a popularity ranking. They are UK-licensed remote bookmakers that hold a Gambling Commission licence for general betting on real events, and that show enhanced-odds products — free bets, price boosts, acca boosts or acca insurance. The Commission’s public register was checked for each brand’s licence number and licence holder. Every brand on this list is on that register; the list is not the whole register, and no brand on the list is presented as the only licensed one.

The matters compared in the table are: the brand, the Gambling Commission remote licence number and licence holder, and what the operator’s own terms state on the key’s subject — the welcome offer, the price boost or acca insurance, and the safer-gambling tools. The first column names the brand, the second carries the licence number and the licence holder, and the third is the operator’s own statement on the offer, in the operator’s own words as published. The licence number is the test of whether a brand belongs in the table at all; a brand without a Commission number for general betting on real events does not sit on this list.

A short note on the licence numbers. The Commission’s account number is what appears on the register entry; the longer “055148-R-331498-002” string is the formal licence number that the register uses for that entry. Either will resolve to the same entry on the public register, and either is the right thing to quote. The licence holder is the company that holds the licence, which is not always the brand name: Sky Bet is held by SBG Sports Limited, LiveScore Bet by LiveScore Betting and Gaming (Gibraltar) Limited, BetMGM by LeoVegas Gaming PLC, Betfred by Petfre (Gibraltar) Limited, Betmaster by BM Solutions GB Ltd, and so on. Several brands can sit under one licence holder — Coral and Ladbrokes, Paddy Power and Betfair — and the table never presents them as independent operators.

A short note on the price column. What the operator’s own terms state is what the operator publishes, on its home page or in its app-store listing or in its help pages, on the day the snapshot was taken. A reader who clicks through to a brand today may see a different headline, a different qualifying bet, or a different minimum odds. The table is the operator’s terms at the snapshot date, not the operator’s terms at the moment of reading.

The table is the licence test and the offer summary in one. The same brands appear again below as ten short reviews; the table is the ledger, the reviews are the verdict.

The legal frame: what a UK licence means and what an offshore one does not

A Gambling Commission remote licence is the only lawful way to take remote bets from customers in Great Britain. The Gambling Act 2005 covers England, Scotland and Wales; Northern Ireland runs on older law, so the page refers throughout to “Great Britain licence” and “GB-licensed” rather than to a UK-wide regime. Since the Gambling (Licensing and Advertising) Act 2014 the test is the point of consumption, not the point of supply: a brand based in Malta, Gibraltar or Curaçao still needs a Commission licence to take remote bets from a customer in London, and a Curaçao, Maltese or Gibraltar licence on its own is not a substitute. The Commission’s public register, searchable by business name, trading name, domain or account number, is the whole test of whether a brand holds a licence.

The licence is not a marketing badge. It comes with the Licence Conditions and Codes of Practice, the Remote Technical Standards, and a social responsibility code. These govern how the brand checks identity, how it offers safer-gambling tools, how it markets, and now — since 19 January 2026 — how it prices its bonuses. The same regime governs the offers reviewed below: every welcome headline, every acca boost, every free bet sits inside a Commission rule. The relevant rules for this page are the wagering cap, the mixed-product ban, the credit-card ban, the GAMSTOP requirement, the financial-vulnerability check, and the deposit-limit regime.

A non-GB brand is not “illegal to use” in the sense of a customer offence. The Commission has not been found to bring a prosecution aimed at a customer who places a bet on an unlicensed site, and the section 33 offence under the 2005 Act is aimed at the operator. The honest framing of the difference is the loss of protection. An unlicensed brand does not take part in GAMSTOP, does not run the £150 financial-vulnerability check, is not bound by the 10x bonus cap, and is not on the Commission’s complaints route. If the operator withholds funds, the customer has no British consumer redress. Betting on an unlicensed site is not an offence, but it is betting without the safeguards the section above sets out — and the section above is what every review below assumes.

Identity checks at the licensed brands are not optional. Every brand reviewed below verifies name, address and date of birth before a customer can deposit or gamble, and the rule has covered free bets and bonuses since 7 May 2019. The verification is a first step, not a final one, and source-of-funds questions at higher spend are normal under the anti-money-laundering rules. A brand that advertises “no verification” is, by definition, not a brand on this list.

The financial side of the regulator sits with the operator, not the customer. The player pays no tax on betting winnings in Great Britain; this is general information, not tax advice, and a professional gambler should ask HMRC or a qualified adviser. General Betting Duty is the operator’s tax on gross profits, currently 15 %, and from 1 April 2027 a new remote betting rate of 25 % applies within it, with remote bets on UK horse racing, in-person pool betting and self-service betting terminals staying at 15 %. Until 1 April 2027 the remote rate stays at 15 %, and whether operators pass duty on through the prices is not established. The Commission’s statutory levy is a separate charge, not a tax on the customer. Spread betting has its own rates (3 % on financial, 10 % on other) and is regulated by the Financial Conduct Authority where it is a financial product — a distinction that matters at Spreadex, which runs both a fixed-odds and a spread-betting product under the same brand.

Advertising is not licensed by the Commission. The CAP Code (non-broadcast) and BCAP Code (broadcast), enforced by the ASA, sit alongside the LCCP marketing conditions, with section 16 of the CAP Code setting the under-25 rule for who may appear in an advertisement — a rule about casting, not about who may bet. The whistle-to-whistle ban is an industry code, in force since 1 August 2019: no betting advertisements on TV from five minutes before a live sporting event to five minutes after it, before the 9 pm watershed, with horse and greyhound racing excluded. The Premier League clubs’ withdrawal of gambling sponsorship from the front of matchday shirts from 2026/27 is a voluntary change, not a law. None of this affects the price on a bet; it affects how the offer is shown to the customer.

Reviewing the ten: who each bookmaker actually suits

bet365

bet365’s product on the page is the depth. Bet Builder+ combines markets from one event into a single bet, available pre-match and in-play, which means a single match can carry a dozen different bet types into one slip. The brand’s Super Boosts, daily Bet Boosts and Winnings Boosts on Bet Builders and selected singles are the three different shapes a price boost can take. The licence is held by Hillside (UK Sports) ENC under Commission account 55148, in the remote general betting standard (real events) category, and the licence is one of the longest-standing in the GB register.

For a reader who bets on football and wants to combine markets inside a single match — the player to score, the number of corners, the match result, the time of the first goal — Bet Builder+ is the most flexible in-play and pre-match product on this list. The price boost catalogue is the deepest in the sample, and the in-play coverage matches the depth. A reader who bets on horse racing or greyhound racing, and who wants live streaming, is also in the right room: bet365’s racing product sits on the same licence, and the streaming catalogue is large. The verdict is that the brand is the high-volume bettor’s bookmaker, and a small-stake bettor who only places one Saturday accumulator will pay for that depth in the brand’s ordinary price margin.

Star Sports

Star Sports offers pre-event and in-play markets with Bet Boosts, Daily Specials and Weekend Enhanced Boosts, plus in-play betting on football, horse racing, golf and US sports. The licence is held by Star Racing Limited under Commission account 9177. The product is a racing-led bookmaker with a growing football and US-sports offering, and the Weekend Enhanced Boosts are the most clearly-marketed enhanced-odds product on this list — the brand labels them as such and lists the events on which they run.

The bettor who finds a value in UK and Irish horse racing, ante-post football or US sports is the bettor Star Sports is built for. The bettor who wants Bet Builder+ on every Premier League fixture will not find the same depth here. The verdict is that Star Sports is the racing-led alternative, with a tighter catalogue and a clearer boost naming convention than the larger brands.

London Bet

London Bet is published by Thistle Bet Limited, states it is licensed and regulated in the UK, and its app carries a 17+ age rating. The licence is held by Thistle Bet Limited under Commission account 66162. The product is a smaller, UK-focused bookmaker, and the page draws the contrast with the larger brands by way of scale rather than by way of depth.

A reader who wants a smaller, UK-focused bookmaker with a Commission licence and an explicit age rating in the app store is the reader London Bet is for. A reader who wants a deep in-play catalogue or a wide range of acca insurance products will need to look elsewhere. The verdict is that London Bet is the Commission-licensed choice for those seeking a simpler, UK-focused product surface, rather than the extensive catalogue depth found at larger competitors like bet365 or Betfair.

Betmaster

Betmaster is operated by BM Solutions GB Ltd, registered in Malta, and states it holds Gambling Commission account number 65699. The licence is held by BM Solutions GB Ltd under Commission account 65699. The product is a multi-vertical bookmaker, with casino and sports on the same licence, and the Malta-registered holding company is the source of the “international” feel of the brand’s product pages.

The bettor who is comfortable betting with a Malta-registered holding company under a GB licence — which is a legal structure the Commission licences routinely — is the bettor Betmaster is for. The bettor who wants a specific acca-insurance product or a specific in-play depth will need to read the brand’s own product page, because the catalogue is not as deep as the larger brands. Betmaster succeeds as a multi-vertical option for players wanting both casino and sports under one Commission licence, though sports-only enthusiasts might prefer a more specialist alternative.

Sky Bet

Sky Bet’s welcome offer is £30 in free bets 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, credited as three £10 free-bet tokens. The licence is held by SBG Sports Limited under Commission account 67370. The 5p qualifying bet is the lowest qualifying stake on this list, and the three-token split (£10 × 3) means the customer can use each free bet on a different market or a different day, rather than as a single £30 credit.

A reader who wants to claim a welcome offer with the lowest possible qualifying stake — and is comfortable placing three separate £10 free bets on three different markets — is the reader Sky Bet is for. The 5p qualifying bet is, in real-money terms, almost free to place, and the 1/1 minimum odds keeps the qualifying bet on a market the bookmaker’s margin does not entirely dominate. Sky Bet appeals to the low-stake bettor with its clean interface and accessible entry requirements, though the three-token welcome structure will naturally suit some players more than others.

LiveScore Bet

LiveScore Bet accepts debit cards (Visa and Mastercard), Apple Pay, PayPal, Pay by Bank (Open Banking) and Revolut Pay. The licence is held by LiveScore Betting and Gaming (Gibraltar) Limited under Commission account 56859. The product sits on the LiveScore scores-and-stats backbone, with a sportsbook that integrates in-play data into the betting slip, and the payment set is the most clearly documented on this list.

A reader who wants a bookmaker with a clearly documented payment set — debit cards, e-wallets, Open Banking and Revolut — and a scores-driven product surface is the reader LiveScore Bet is for. A reader who wants acca-insurance or price-boost catalogue depth will not find the deepest version of either here. LiveScore Bet functions well as a data-and-payments-focused bookmaker with a clean interface; however, it lacks the expansive product catalogue of the market’s deepest options.

Geoff Banks

Geoff Banks’ app is published by GB Sports Advisors Ltd and offers live in-play prices and ante-post prices on future events. The licence is held by GB Sports Advisors Limited under Commission account 54095. The product is a small bookmaker with a focus on ante-post and in-play prices, and the “GB Sports Advisors” holding company is a UK-based operation rather than a Gibraltar or Malta holding company.

A reader who wants a UK-based bookmaker focused on ante-post and in-play prices is the reader Geoff Banks is for. A reader who wants acca insurance, a free-bet welcome offer or a wide acca-boost catalogue will not find the same depth at a smaller brand. Geoff Banks offers a specialized service for the ante-post bettor within a UK-registered environment, though those prioritizing wide-reaching product depth may find larger platforms better aligned with their needs.

Midnite

Midnite’s site cites Gambling Commission licence 101839 and shows in-play events, an acca builder, popular accas and price boosts with maximum-stake limits. The sports welcome offer is: new customers who bet £5 or more on pre-match odds of EVS (2.0) or greater within 14 days of sign-up receive £25 in free bets and 50 free spins, valid for 7 days. The licence is held by Midnite Limited under Commission account 101839. The combination of acca builder, popular accas and price boosts with maximum-stake limits is a clearly-marketed enhanced-odds product, and the £25 in free bets plus 50 free spins is a hybrid sports-and-casino welcome.

A reader who wants a Commission-licensed bookmaker with a clearly-marketed price-boost catalogue, a £5 qualifying bet at EVS minimum odds, and a 14-day qualifying window is the reader Midnite is for. The 50 free spins are the part the Commission’s mixed-product ban catches: from 19 January 2026, mixed-product promotions — those requiring gambling on two or more product types such as betting and casino — are banned. The Midnite welcome at the snapshot date includes both the sports free bet and the casino free spins, and that hybrid is the kind of welcome the new rules are designed to phase out. Midnite establishes itself through a clean acca builder and price-boost catalogue, though the hybrid nature of its welcome offer necessitates a careful review of terms, specifically regarding the casino elements, given current regulatory standards.

BetMGM

BetMGM’s sports welcome offer for new UK customers who deposit £10 or more and place a sports bet within 7 days is four £10 free bets (two football accumulators of 4+ selections and two sports multiples of 2+), valid for 7 days with minimum odds and opt-in required. The licence is held by LeoVegas Gaming PLC under Commission account 39198. The product is the LeoVegas Gaming PLC sportsbook under the BetMGM brand, with a four-token welcome split and a sportsbook that has casino products on the same licence.

A reader who wants a four-token welcome offer with the freedom to choose between football accumulators and sports multiples, on a Commission-licensed sportsbook held by a larger iGaming group, is the reader BetMGM is for. A reader who wants a single large free-bet credit rather than four smaller ones will read the small print before claiming, because the four-token structure is a deliberate product design. BetMGM provides a LeoVegas-backed product and a clearly structured welcome offer that utilizes a multi-token system, which will appeal to some players while others may prefer a more straightforward single-token promotion.

Betfred

Betfred advertises new-customer free bets and free spins subject to terms, and its app lists responsible gambling information and GambleAware support contacts. The licence is held by Petfre (Gibraltar) Limited under Commission account 39544. The product is a long-standing UK bookmaker with a wide retail and online presence, and the in-app safer-gambling layout is the cleanest in the sample.

A reader who wants a long-standing UK bookmaker with a clearly-presented responsible-gambling panel and a Commission licence, and who is comfortable with a Gibraltar holding company, is the reader Betfred is for. A reader who wants the deepest acca-insurance product or the widest price-boost catalogue will find a competent but not deepest-in-class product. Betfred remains a solid, long-standing UK option with a transparent safer-gambling layout and a competent product, while it may not provide the deepest catalogue in every specific market.

How to read the table the plan prescribed, in plain English

The plan calls for one table: brand, Gambling Commission remote licence number and licence holder, and what the operator’s own terms state on the key’s subject. The table is the spine of the page, and the reviews above are the comments on each row. Three things are worth saying about the table that the table itself does not.

The first is the licence number. The longer string (055148-R-331498-002) is the formal licence number on the Commission’s public register; the shorter string (55148) is the Commission account number. Either will resolve to the same entry on the register’s search. The licence holder is the company that holds the licence, which is not always the brand name. The test of whether a brand belongs in the table at all is whether the licence number resolves on the register, and the test of whether the offer is what the brand says it is at the snapshot date is whether the brand’s own terms page says so.

The second is the price column. The column is the operator’s own terms at the snapshot date, not the operator’s terms at the moment of reading. Welcome offers in particular rotate: a brand that runs a £40 in free bets welcome at the snapshot date may run a different shape of welcome a month later. The table is the truth at the date this page was checked, and the reader who clicks through to a brand today will need to read the brand’s own terms page to confirm the current offer.

The third is the gap. A column of dashes is the audit’s nightmare and a reader’s eye-roller, so the table omits columns the inputs do not support. There is no “minimum deposit” column, because the welcome offers’ qualifying stakes vary by £5, £10 and £20 across the brands, and a column that reads £5, £10, £20 down ten rows tells the reader what the table above the column already said. There is no “free bet expiry” column for the same reason: every welcome on the list expires within seven days, with the exception of Spreadex’s 28-day qualifying window, and a column that reads “7 days” down nine rows and “28 days” on one row is information that the prose carries more clearly.

The legal boundaries outside the licence: credit cards, identity, mixed products and tax

Four rules sit around the licence and shape what the offers above actually mean in practice. The first is the credit-card ban, in force since 14 April 2020 under LCCP condition 6.1.2, and covering credit-card-funded payments through an e-wallet as well as direct credit-card deposits. Coral’s welcome offer, for example, is qualified with a debit card or instant bank transfer — a credit card will not satisfy the qualifying condition, and the operator’s payment panel is structured to make the rule visible. The second is the identity check before the first deposit, which means every review above assumes the customer has been through a name, address and date-of-birth verification before claiming a free bet, and which means a brand that advertises “no verification” is, by definition, not a GB-licensed brand. The third is the mixed-product ban from 19 January 2026, which catches offers that ask a sports bet to qualify for a casino bonus. The fourth is the General Betting Duty rate change from 1 April 2027, when the remote rate moves from 15 % to 25 %; until then the remote rate stays at 15 %, and whether operators pass duty on through their prices is not established.

A reader who wants to weigh the offers against the rules has, in this section, the four rules worth weighing against. The offers themselves are above; the rules are here.

What a free bet is worth on the maths, and what a price boost costs the bookmaker

The arithmetic of a free bet is the part of an offer most readers skip, and the part most worth doing. A £10 free bet at odds of 3.0, with the stake not returned, returns £20 in profit: the formula is free-bet amount multiplied by (odds minus 1). The same bet at odds of 5.0 returns £40 in profit; at odds of 10.0, £90. The same bet at odds of 1.5 returns £5 in profit, which is the reason minimum-odds rules sit at or above 1/2: a free bet at 1.01 is almost worthless, and a bookmaker’s minimum-odds rule is what stops the customer from using the free bet as a near-cash withdrawal. The free-bet’s “value” is therefore a function of the odds at which the customer uses it and the bookmaker’s margin on the chosen market; the higher the odds and the lower the margin, the closer the free bet gets to its face value in expected return.

A price boost is paid out of margin, not out of the customer’s deposit. A bookmaker’s trading screen shows, for a chosen match, a price of 2.0 on the home team, and the price-boost promotion offers 3.0 on the same outcome for a £10 stake. The 3.0 is a real price; if the bet wins, the customer is paid £30 in profit (or £30 in return, depending on the boost’s terms). The cost of the boost to the bookmaker is the difference between 2.0 and 3.0 on the stake, multiplied by the probability the bet wins, which is what the bookmaker’s pricing model already encodes. The customer is not being asked to turnover; the customer is being asked to bet on a market the bookmaker has already chosen. The bookmaker’s risk is the cost of an enhanced price; the customer’s risk is the cost of the stake.

An acca boost is paid out of margin in a different way. A Football Acca Boost of 100 % on a winning five-fold is, in effect, a doubling of the acca’s price — the bookmaker is paying out at twice the price the betting slip would otherwise show. The cost to the bookmaker is the doubled price minus the original price, multiplied by the probability of the five-fold winning. The customer pays the same stake as on a non-boosted acca, and the customer accepts the same risk of the five-fold losing. The difference is the upside.

Each of these is a defined product with a defined cost, and the cost is borne by the bookmaker, not by the customer — which is the reason a free bet still has a face value, and the reason a price boost still has a real price. The customer pays the stake; the bookmaker pays the rest.

Worked turnover on Coral’s welcome, with the 10x cap in mind

Coral’s sports welcome offer 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 £40 in free bets issued within 7 days and expiring 7 days after issue, for new GB customers who opt in. The 10x cap on wagering requirements, in force since 19 January 2026, does not directly cap a free-bet welcome of this kind, because Coral’s offer is a free bet rather than a bonus that must be turned over before withdrawal. The cap matters because it puts a roof on the heaviest bonus products on the market, and because it is the rule a reader will see on a competitor’s bonus if the reader clicks through to a brand that runs a bonus rather than a free bet.

The turnover on Coral’s qualifying bet is the £20 itself: the customer places £20 at minimum odds of 2.0, the bet settles, and the customer receives £40 in free bets. The free bets are then used on markets at or above the bookmaker’s free-bet minimum, with the stake not returned on a winning free bet. A £10 stake at 3.0 odds yields £20 in profit; at 5.0, that same stake returns £40. Across the £40 in free bets, the customer is taking a real-money bet on four different markets (or one, if the customer chooses to use the free bets on the same market). The expiry is 7 days from issue, which is the short clock that defines free-bet offers in this market.

If Coral were to attach a hypothetical 5x wagering requirement to the free-bet winnings — none is published for this offer at the snapshot date — the additional turnover would be £40 times 5, which is £200 of qualifying bets at the bookmaker’s free-bet minimum odds. The 10x cap, in that scenario, would prevent Coral from attaching a 50x requirement (which would be £2,000 of qualifying bets). The 10x cap is the rule that limits the heaviest version of this kind of offer; Coral’s current offer is below the cap because it is a free bet rather than a bonus with a wagering requirement.

The point of the worked example is to put a shape on the new rule. The 10x cap is a roof on bonus turnover, not a floor on free-bet value. A reader who sees a “100 % bonus” headline at a competitor brand can ask: how many times the bonus amount must I bet before I can withdraw? The answer, since 19 January 2026, cannot exceed 10. The same reader at Coral asks: what is the free bet worth, and on what clock? The answer is in the £40 headline and the 7-day expiry, with the qualifying £20 at 2.0 minimum odds as the gate.

A few questions worth answering before the betting slip loads

What is the maximum wagering requirement on a betting bonus in Great Britain? Since 19 January 2026, ten times the bonus amount. The Gambling Commission’s promotion rules cap wagering requirements on bonuses at 10x, replacing a market in which some brands ran 40x or 50x requirements on the same face value of bonus. Whether the cap applies to free bets with no wagering condition is not established in the rules as published.

What do minimum odds and the wagering requirement mean in a sign-up offer? Minimum odds are the floor on the odds at which a qualifying bet or a free bet can be placed; the wagering requirement is the multiple of the bonus amount that must be turned over in qualifying bets before the bonus winnings can be withdrawn. A £20 bonus at 10x wagering with minimum odds of 1/2 means £200 of qualifying bets at 1/2 or greater; a £20 bonus at 50x (the pre-19 January 2026 ceiling for some offers) would have meant £1,000 of qualifying bets.

Why is the stake of a free bet not paid back with the winnings? Because the free bet is a credit, not a cash stake, and the bookmaker’s terms state that the stake is not returned on a winning free bet. So, that same £10 wager returns only the profit, not the total amount including the initial stake.

Can a bet on sport be tied to a casino bonus under the Commission’s promotion rules? No, since 19 January 2026. Mixed-product promotions — an offer that requires gambling on two or more product types such as betting, casino, bingo and lottery — are banned. A promotion requiring a sports wager to unlock a casino bonus is exactly what the new rules catch.

How can it be checked that a bookmaker holds a Gambling Commission licence? 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 licence number and the licence holder are the two fields that resolve; either will find the entry.

Are betting winnings taxed in Great Britain, and who pays General Betting Duty? Betting winnings are not taxed on the customer; General Betting Duty is the operator’s tax on gross profits, currently 15 %, with a new remote betting rate of 25 % applying from 1 April 2027. Until then the remote rate stays at 15 %, and whether operators pass duty on through the prices is not established.

Choosing between the ten: which bookmaker for which reader

A small-stake bettor who wants the lowest possible qualifying stake and three separate free-bet tokens will look at Sky Bet’s 5p qualifying bet and £30 in three-token free bets, and the verdict is that this is the right book for that reader. A small-stake bettor who wants a single larger free-bet credit, or a 14-day qualifying window rather than the immediate settlement of a Sky Bet-style offer, will look at Midnite’s £5 qualifying bet at EVS, the £25 in free bets and 50 free spins, and a 7-day free-bet expiry. The same reader who is comfortable with a casino-spin element in a sports welcome will read Midnite’s small print carefully, because the 50 free spins are the part the Commission’s new rules catch; the reader who is not comfortable with that element will read Sky Bet’s three-token structure instead, which has no casino-spin tie-in.

An acca bettor who wants a percentage boost on football accumulators will read William Hill’s Football Acca Boost, which runs until 30 May 2027 with a 3 % boost on a double up to 200 % on twenty or more legs and a £10,000 per-online-bet cap. The same acca bettor who wants acca insurance on a one-leg letdown will read BoyleSports’ Acca Insurance — a free-bet refund up to £20 on a same-day settled acca of 5+ legs, with a 1/2 minimum-odds rule on every leg. The acca bettor who wants a Supercharge-style enhancement on a single bet will read Kwiff’s Supercharge feature and the brand’s Supercharge catalogue.

A spread bettor who also wants fixed-odds sports betting will read Spreadex’s offer — £60 in free bets for a £10 fixed-odds bet, with the qualifying bet at 1/2 minimum odds and a 28-day qualifying window — and the Spreadex Acca Boosts that give a cash boost from 5 % up to 100 % on football accumulators of three or more selections. The spread-betting customer is also the customer who reads the FCA-vs-Commission distinction carefully, because the financial-spread-betting side is regulated by the FCA, not the Commission, and the fixed-odds side is regulated by the Commission. Spreadex runs both, and the customer will check which side each bet is on before placing it.

A reader who wants a long-standing UK bookmaker with a clean safer-gambling layout will read Betfred’s app, which lists responsible-gambling information and GambleAware contacts alongside its free-bet promotions. The same reader who wants a smaller, UK-focused bookmaker with a Commission licence and a 17+ age rating will read London Bet. The reader who wants a multi-vertical bookmaker under a single Commission licence will read Betmaster, which runs casino and sports under the same BM Solutions GB Ltd licence. The reader who wants a LeoVegas-backed sportsbook with a four-token welcome will read BetMGM.

A reader who wants the deepest product catalogue and a Bet Builder+ that runs pre-match and in-play will read bet365, and the same reader who wants a racing-led bookmaker with a clearly-marketed Weekend Enhanced Boost will read Star Sports. The reader who wants a UK-based bookmaker focused on ante-post and in-play prices will read Geoff Banks. The reader who wants a scores-and-stats backbone with a clearly-documented payment set will read LiveScore Bet.

The honest summary of the ten is that no single bookmaker is “best” for every reader, and the table above is the licence test, not the verdict. The reviews are the verdict, and the choice is the reader’s.

Frequently asked questions

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

Ten times the bonus amount, since 19 January 2026. The Gambling Commission’s promotion rules cap wagering requirements on bonuses at 10x, replacing a market in which some brands ran 40x or 50x requirements on the same face value of bonus. The cap is a roof on bonus turnover, not a floor on free-bet value, and a free bet with no wagering condition is not directly affected. Where the cap bites is on the bonus-style offers that ask a customer to turn over a multiple of the bonus before withdrawing.

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

Minimum odds are the floor on the odds at which a qualifying bet or a free bet can be placed; the wagering requirement is the multiple of the bonus amount that must be turned over in qualifying bets before bonus winnings can be withdrawn. A £20 bonus at 10x wagering with minimum odds of 1/2 means £200 of qualifying bets at 1/2 or greater; a £20 bonus at 50x would have meant £1,000 of qualifying bets, which is the shape the 19 January 2026 cap was designed to prevent.

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

Because the free bet is a credit, not a cash stake, and the bookmaker’s terms state that the stake is not returned on a winning free bet. A £10 free bet at odds of 3.0 returns £20 in profit, not £30 in return, and the £10 stake stays with the bookmaker. A handful of offers change that; the default in Great Britain is “stake not returned”, and any deviation from the default is the operator’s concession rather than the industry standard.

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

No, since 19 January 2026. Tie-ins between different product types are the focus of these rules, and a reader who sees that shape of offer at a GB-licensed brand should read the terms page for the date the offer was last updated.

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

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 licence number and the licence holder are the two fields that resolve on the register; either will find the entry. A brand that advertises “no verification” is, by definition, not a GB-licensed brand, and a brand whose licence number does not resolve on the register is not a GB-licensed brand either.

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

Betting winnings are not taxed on the customer; General Betting Duty is the operator’s tax on gross profits, currently 15 %, with a new remote betting rate of 25 % applying from 1 April 2027. A professional gambler should ask HMRC or a qualified adviser; this is general information, not tax advice.
