A price boost looks like free money. It rarely is. The headline number gets bigger, the marketing claim reads “best odds”, and the fine print underneath decides whether the boost is worth the bet that unlocked it. This page works through ten UK-licensed bookmakers, looks past the welcome banners, and counts what each promotion actually pays the punter who takes it.

Last verified: 27 October 2026 against the Gambling Commission’s public register.

Responsible Gambling in Great Britain: The Frame Around Every Offer

Every promotion in this comparison is read against the same British safeguards. They are the floor under the offers and the ceiling on what an operator can ask of a customer. The rest of the page assumes them; this section names them.

The Gambling Commission is the regulator. It licenses every online bookmaker that takes a bet from a customer in Great Britain, sets the social responsibility code that licensees must follow, and runs the public register that lets anyone check a brand’s status. Since 2019 a customer cannot deposit or place a first bet at a licensed site without passing name, address and date-of-birth verification. A free bet is not a way past it: a bonus is still gambling under the Commission’s rules, and verification runs before the bonus is credited.

GAMSTOP is the national self-exclusion register. Every UK-licensed remote operator is a member. A self-exclusion can run six months, one year, five years, or five years with auto-renewal, and after the minimum period a further seven years of exclusion continues unless the customer asks GAMSTOP to remove it. An excluded customer who tries to register or deposit at a participating site is stopped at the door.

A financial vulnerability check runs once a customer’s net deposits across a rolling 30-day window cross £150. It is a public-record check, not an income check and not a credit search. A separate affordability assessment, the kind that asks about wages and outgoings, sits in a Commission plan announced in July 2026 with no start date written in. Operators are required to offer deposit limits on a fixed time frame; the first phase of those changes applied from 31 October 2025, and a second phase was pushed to 30 September 2026.

Credit cards have been banned for gambling since April 2020, including credit-card-funded payments through an e-wallet. Debit cards and bank-based payments stay outside that ban. The bettor who hits a deposit ceiling at one brand and tries the same card at another will find the same ceiling, because the cap is the customer’s, not the wallet’s.

Help exists outside the operators. GamCare runs the National Gambling Helpline. GambleAware funds treatment. The NHS runs gambling clinics. Gamblers Anonymous runs meetings. None of these routes requires the customer to have an open account with the operator, and the Commission expects licensed brands to point customers at them.

Two things to carry through the rest of the page. The first: a GB licence is the price of admission, and ten of the brands below hold one. The second: a price boost is still a bet on a margin-loaded market, and the protection the regulator offers the punter is the same whether the price is boosted or not.

Bonuses and Free Bets: What the Headline Really Buys

Price boosts, free bets, acca insurances, enhanced odds, bet credits, “risk-free” refunds. The marketing language is thick and the categories overlap. Underneath it sits a small set of distinct offer types, each with its own arithmetic and its own cost to the punter.

The Commission Rule That Sets the Ceiling

Since 19 January 2026 the Gambling Commission has capped wagering requirements on bonuses at ten times the bonus amount, and banned mixed-product promotions that ask a customer to gamble on two or more product types to clear an offer. A book bonus that hands out £10 in casino credit for placing a sports bet is the textbook mixed-product case the rule catches. A sports-only free bet on a sports-only market is not.

The cap lands directly on the bonus. A £10 bonus at 50x wagering needed £500 of qualifying bets before any winnings could be withdrawn; under the cap no more than £100 of qualifying bets is required. Where the cap ends is where a free bet has no wagering condition at all. Whether the 10x rule reaches those is not established in writing, and the question is worth asking the operator’s customer support before claiming an offer of that shape.

What “Free Bet” Actually Means

A free bet credits the punter’s account with a stake the house pays for, and pays back only the winnings. A £10 free bet at 3/1 returns £30 in profit, not £40. The stake is not returned, and the difference between a free bet and a cash bonus is the stake: a cash bonus credits the account with money that can be withdrawn or staked, and a free bet is a single-use token. The offers in this comparison lean heavily on free bets because that is the form most British welcome offers now take.

Two further terms attach to nearly every free bet. The first is a minimum odds floor: a free bet is usually restricted to selections at or above a stated price, often 1/2 (1.50) or 4/5 (1.80). The second is an expiry, often seven days from the moment the free bet is credited. A free bet the punter never uses, or uses at the wrong price, is a free bet that paid the operator for the marketing.

Price Boosts and Enhanced Odds

A price boost raises the odds on a named market. The boost sits on top of the operator’s own price, so the margin the operator is taking on that market is the same as on any other price, and the boost is the punter’s only real gain. A Super Boost at 33/1 on a goalscorer market is still a market the operator prices to a margin it controls. The boost is not a free lunch; it is a discount.

Several operators in this comparison run a daily price-boost shelf, a Supercharged section, or a Bet Boost button on selected selections. Where the boost is on a market the punter would have bet on anyway, the boost is pure upside. Where the boost is on a market the punter would not otherwise have touched, the boost is a marketing nudge to take a worse bet.

Acca Insurance and Acca Boosts

Acca insurance refunds a stake as a free bet if one leg of a qualifying accumulator lets the punter down. Acca boosts add a percentage to the winnings of a winning acca, scaling with the number of legs. Both are paid in free bets, both have minimum-stake and minimum-odds floors, and both have an expiry. They sit on top of the accumulator’s own margin, which is already higher than a single’s because the legs multiply.

The 10x Cap in Practice

A worked example shows the cap’s weight. A book bonus of £40 with a 10x wagering factor asks the punter to place £400 of qualifying bets before the bonus converts to withdrawable cash. At a flat £10 per bet the punter needs forty bets. At a £20 stake the punter needs twenty. At £50, eight. The actual clearing cost depends on the margin of the markets the punter wagers on, and the average punter clears the bonus by losing the expected share of the turnover to margin. The cap is a ceiling; the cost is whatever the markets underneath charge.

The Comparison: 10 UK Bookmakers With Price Boosts

The table below holds the licence facts and the price-boost posture of each operator. The operator write-ups after it walk through the offer shape, the qualifying terms, the expiry and what a typical punter pays to clear it.

Matchbook is the odd one out in this set. It is a betting exchange, and exchanges do not run price-boost shelves the way a traditional book does. The 110-day commission-free window is the offer; commission is the price of every bet afterwards.

Matchbook: Commission-Free Window, Exchange Mechanics

Matchbook’s new-customer offer is 110 days of commission-free betting from the moment a customer registers and deposits. The qualifying mechanic is a registration with the code shown in the listing and an opening deposit; standard commission applies to every bet placed after the 110 days end. The exchange model sets the price through back and lay bets between customers, and the operator’s cut is commission on net winnings rather than a margin baked into the price.

A punter used to a traditional bookmaker sees a different shape here. The price on a Premier League match is set by what other customers are willing to back and lay, and the operator’s take is commission rather than overround. There is no boosted odds shelf to walk through, and the welcome offer is a discount on the operating cost rather than a sweetener on a particular selection. The Commission account is 039504-R-319407-024, with Triplebet Limited as licence holder.

A punter who already understands exchange liquidity and commission tables will read this as the natural home. A punter who wants a Bet Boost button on a Sunday acca is in the wrong shop.

Coral: Daily Shaker, Odds Booster, Welcome Pair

Coral runs a daily Reward Shaker, a free-to-play game that hands out free bets and other promos once a day, and an Odds Booster that runs across hundreds of markets. The welcome offer is a £40 free bet bundle for a £20 qualifying bet: deposit and bet £20 or more at minimum odds of 2.0 (1/1), the £40 in free bets arrives within seven days and expires seven days after issue, and only new GB customers who opt in and fund the deposit with a debit card or instant bank transfer qualify. The app adds free-to-play games including Football Super Series with a £10,000 jackpot.

The licence is held by LC International Limited under Commission account 054743-R-330863-014. The payment-method roster runs to Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly.

The Shaker is the part most punters underestimate. It is a daily nudge back to the app, and the free bet it hands out is paid as a free bet rather than cash, so the stake is not returned with any win. The Odds Booster covers hundreds of markets, which is a wide shelf, but the boost amount is set by the operator and varies market to market. The welcome offer sits inside the 10x cap comfortably: no wagering factor, a free bet paid as a free bet, and a clean seven-day window.

NetBet: Daily Boosts and a Bet Builder

NetBet’s app advertises Daily Boosts, Profit Boosts and free bet offers, alongside a Bet Builder that recalculates odds in real time and sports stats for the major leagues. The licence is held by Netbet Enterprises Limited under Commission account 039170-R-319343-032. The welcome offer is not detailed in the public app listing, and the daily shelves are the operator’s main draw for a punter who already has an account.

The Bet Builder is the most transparent of the in-app features: the odds update as the punter adds or removes a selection, and the margin the operator takes on the combination sits inside that live number. The Daily Boost is the more conventional product, with named selections at raised prices. A punter who uses the builder for singles already has a feel for the operator’s margin; the boost is a small discount on top.

A punter who wants daily price boosts and a working Bet Builder on the same app has both here, and the licence sits in the right place. The welcome offer’s specific shape is best confirmed in the app before the qualifying bet, because the public listing does not carry every term.

Unibet: Twenty-Six Years of UK Trading

Unibet states it has operated since 1999, and the UK site is run by Platinum Gaming Limited, Gibraltar, under Commission account 045322-R-324275-019. The welcome offer matches Coral’s headline figure: a £40 free bet bundle for a £20 qualifying bet at minimum odds of 2.0 (1/1), with free bets expiring within seven days of issue and a debit card or instant bank transfer deposit. The app adds daily Uniboosts, Bet Builder, in-play betting, live streaming through Unibet TV, Best Odds Guaranteed on horse racing and Cash Out on thousands of markets.

The offer profile is the most complete in the comparison. A punter who wants a price boost, a bet builder, a live stream and cash out on the same bookmaker does not need to hold a second account. The trade-off is the depth of the welcome offer’s free bet window: seven days is tight, and a punter who waits until the weekend to use the token will find it gone.

The 10x cap does not bind the welcome offer. The free bet is paid as a free bet, no wagering factor is stated, and the qualifying bet is a single £20 stake at minimum odds of 2.0 (1/1). The cost of clearing is the qualifying bet itself: at 2.0 with the operator’s margin built in, the expected loss is the margin share of the £20.

Betboro: A Single Welcome Boost, A Tight First Bet

Betboro’s sports welcome offer is a 100% matched free bet of up to £25 on the first qualifying wager. A debit card deposit of at least £10 and a first bet between £5 and £25 with at least three selections, each at 3/5 (1.60) or higher, is required. The licence is held by Webmedia Development N.V. under Commission account 044181-R-324363-007. No daily price-boost shelf is flagged in the public terms.

The shape of the offer is the tell. A first bet of up to £25 with three legs each at 1.60 or higher is a small accumulator with a long minimum price. The combined price of three 1.60 legs is 4.096, so the qualifying bet itself is a market the operator has priced to its own margin, and the matched free bet is paid as a free bet rather than cash. A punter who backs a 1.60 treble once a week will recognise the shape immediately; a punter who backs singles will not.

A punter who already builds small accas will read this as a clean welcome. A punter who wants a daily price boost to lean on will not find one in the public listing.

London Bet: A Clean Licence and a Short Public Footprint

London Bet is published by Thistle Bet Limited, holds a Commission licence under account 066162-R-340278-004, and its app carries a 17+ age rating. The public App Store listing is short on product detail, and no daily price-boost shelf or named welcome offer is listed. A punter who wants the operator’s full offer profile will find it in the app and the operator’s own terms rather than a public listing.

The licence is current and the operator is a Commission licensee. The promotional surface area of the brand is narrower than the bigger names in this comparison, and a punter who prizes a thick daily-boost shelf will read that narrower surface as a reason to keep the bigger bookmaker in the rotation.

10bet: A Bonus Headline Worth Reading Slowly

The 10bet app advertises a 100% up to £50 betting bonus for UK sign-ups, with daily free bets and free spins on the same listing. The licence is held by Blue Star Planet Limited under Commission account 043173-R-322899-023. The product page does not carry the full terms of the welcome bonus, and the daily-free-bet shape sits in the customer terms rather than the App Store copy.

The “free spins” line is the part that does the work. A sports welcome bonus that arrives with a free-spins tail is a mixed-product promotion under the Commission’s January 2026 rules, and the shape of the offer is the first question to ask the operator’s customer support. A pure sports free bet stays well inside the rules; a sports-plus-casino bundle does not.

The £50 ceiling is the largest welcome figure in this comparison. The cost of clearing is the wagering factor on the bonus, and under the 10x cap no more than £500 of qualifying bets is required to convert the bonus. The actual clearing cost is the margin of the markets the punter wagers on across those bets.

LiveScore Bet: A Wide Payment Rail, A Modest Public Listing

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 056859-R-332720-005. The price-boost terms sit in the in-app promos area rather than the public payment-methods page, and the welcome offer’s full shape is best confirmed in the app.

A punter who has been locked out of a welcome bonus at a competitor by a payment-method restriction will read the payment rail here as a feature in its own right. Pay by Bank and Revolut Pay both route through the customer’s bank rather than a card network, and that route stays outside the credit-card ban in a way that some e-wallet routes do not.

The Commission licence is current, the payment roster is the most public-facing feature in the listing, and the price-boost offer is the part of the operator a punter sees only after the app is on the phone.

Kalooki Sportsbook: A Newer Brand With a Horse-Racing Lean

Kalooki Sportsbook is operated by Kalooki Sports Book Ltd, a company registered as number 12938274, and is licensed by the Gambling Commission under account number 057730-R-333396-005. The brand is a GAMSTOP member. The site advertises 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 product profile leans toward British and Irish racing. Best Odds Guaranteed pays the starting price or the taken price, whichever is higher, and is the kind of concession a racing punter reads as table stakes. Extra place races extend the place-paying positions in selected fields, which is a real edge for each-way punters. The instant-withdrawal claim is a feature the operator makes on its own site and a punter should test before the first withdrawal is needed.

A racing-first punter has a home here. A football-first punter will find a thinner in-play product than the bigger names, and the daily boost shelf’s depth is narrower.

Hollywoodbets: A Welcome Built Around the First Acca

Hollywoodbets’ sports welcome offer is a stake-back free bet of up to £30 on the first qualifying losing accumulator. New players who deposit £10 or more by card get the free bet on a losing first acca with a stake of £10 or more, three or more legs, and combined odds of 4/1 or greater, settled within seven days. One free bet per customer. The licence is held by Hollywoodbets International UK Limited under Commission account 053028-R-330019-013.

The offer rewards the punter who has already decided to bet an acca and loses. A winning first acca pays out at the operator’s normal odds; a losing first acca returns the stake as a free bet of up to £30, with the cap set by the stake the punter placed. The free bet is paid as a free bet rather than cash, with a seven-day expiry from credit.

A punter who backs small accas at combined odds above 4/1 has the welcome offer built into the bet they would have made anyway. A punter who backs singles has to construct a qualifying acca to claim the offer, and that construction adds the operator’s accumulator margin to the underlying bets.

Overview: What a Price Boost Is, and What It Is Not

A price boost is a temporary or standing increase in the odds on a named market. The operator’s own price becomes the floor; the boosted price is the ceiling. The boost sits on top of the operator’s margin, so the punter is paying the same margin the operator always charges and is being given a small discount on top. A boost that raises a price from 5/2 (3.50) to 7/2 (4.50) is a 1.00-point discount on a market the operator still prices to a margin it controls.

A boost is not a margin cut. A boost is not a free bet. A boost is not an arbitrage opportunity against the operator’s own unboosted price, because the punter can only take the boosted price on the terms the operator has set, and the terms usually include a maximum stake, a named market, and a window. A boost that runs across hundreds of markets and applies to singles is the closest the punter gets to a margin cut, and even then the boost amount is operator-set and varies.

The price boost sits inside a wider landscape of British betting promotions. Free bets credit the punter with a stake the house pays for, and pay back only the winnings. Enhanced odds work like a price boost but are usually tied to a one-off event or new-customer offer. Acca insurance refunds a stake as a free bet if one leg lets the punter down. Acca boosts add a percentage to a winning acca’s payout, scaling with the number of legs. Bet builders let the punter combine markets from one event into a single bet, with the operator’s combined margin baked into the live odds. Cash out lets the punter settle a bet before the event is over, at a price the operator sets.

A price boost on a market the punter would have bet on anyway is a clean gain. A price boost on a market the punter would not otherwise have touched is a marketing nudge to take a worse bet at a better-looking price.

Legality and Regulation: The British Frame

The Gambling Commission licenses the commercial market under the Gambling Act 2005, which covers Great Britain. Northern Ireland runs a separate older law, so a GB licence does not extend to customers there, and a brand that holds a GB licence is licensed for Great Britain specifically. The Commission’s public register can be searched by business name, trading name, domain or account number and is the whole test of whether a brand holds a licence. Every operator in this comparison holds one.

The Commission’s reach is the point of consumption. Since 2014 an operator whose remote facilities are used in Great Britain needs a Commission licence wherever the operator is based. A Curaçao, Maltese or Gibraltar licence is not a substitute. Several operators in this comparison are run from Gibraltar; the Commission licence is the British permission, the Gibraltar incorporation is the corporate shape. Both can sit on the same page of the register.

Betting licence types in Great Britain cover remote general betting standard (real events), remote general betting standard (virtual events), remote general betting limited, remote pool betting and remote betting intermediary (the licence for betting exchanges). The Commission’s register lists the categories each licence covers, and an operator’s offer sits inside the categories on its own licence. The brands in this comparison are licensed for remote general betting standard (real events); Matchbook also holds the betting intermediary category that lets it run an exchange.

A minimum age of 18 applies. Name, address and date of birth are verified before the first deposit or first bet, including when the bet is paid for by a free bet or bonus. The verification runs through the operator’s own process, often via a third-party provider, and the punter who cannot pass it cannot move money in or out of a licensed account.

The advertising rules sit with the ASA through the CAP Code (non-broadcast) and the BCAP Code (broadcast), alongside the Commission’s own marketing conditions in the LCCP. Marketing must be socially responsible, must not be of strong appeal to under-18s, and no one who is or seems to be under 25 may feature in gambling marketing. The whistle-to-whistle ban on TV advertising around live sporting events has been in industry operation since August 2019.

Tax sits on the operator, not the punter. The player pays no tax on betting winnings in Great Britain, and that is general information rather than tax advice. 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% will sit within it, with remote bets on UK horse racing, self-service betting terminal bets, pool betting and in-person betting staying at 15%. The Commission’s statutory levy is a separate charge to the operator. Whether an operator passes part of the duty through to customers in lower odds is not established, and the framing should never say the punter pays duty.

The Offshore Alternative

A betting site that does not hold a Commission licence is not licensed for Great Britain, no matter where the site is incorporated. A Curaçao-licensed site that takes bets from a customer in Manchester is breaking section 33 of the Gambling Act 2005 at the operator end. The customer side has no offence attached to it, but the protections do not attach either: no GAMSTOP coverage, no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld, and the 10x bonus cap and £150 vulnerability check do not bind the operator. The Commission does not block unlicensed sites at the ISP level; it works through cease-and-desist notices, search-engine referrals, registrar and host work, and payment-provider pressure. A punter who uses an unlicensed site is gambling on an operator with no British check on it.

The Arithmetic of a Welcome Offer: What It Actually Costs to Clear

The Commission’s 10x cap sets a ceiling. The market margin sets the floor. The two together decide what a punter actually pays to convert a welcome bonus into withdrawable cash.

A worked example with the headline offer in this comparison. A £40 free bet bundle for a £20 qualifying bet is a free-bet offer, not a bonus with a wagering factor. The free bet is paid as a free bet, the stake is not returned, and the punter needs to win at minimum odds of 2.0 (1/1) for the qualifying bet. The clearing cost is the qualifying bet itself: at 2.0 with the operator’s margin built in, the punter’s expected loss on the £20 is roughly the margin share. A typical Premier League match margin sits around 5% to 7%, so the expected loss on the £20 qualifying bet is around £1.00 to £1.40. The free bet is then worth whatever the punter can win on it before it expires.

A £10 bonus at 10x wagering is the cap’s ceiling example. The required turnover is £100. At a flat £5 per bet the punter needs twenty bets. At £10, ten bets. The clearing cost is the margin of the markets wagered, applied to £100 of turnover. At a 5% margin the expected loss is £5. At 7% it is £7. A punter who picks the lowest-margin markets and the smallest qualifying stake keeps the cost down; a punter who picks popular markets and a higher stake pays more.

The 10x cap matters most for the offers that fall just under it. A bonus that would have asked for £500 of turnover at 50x is now asking for £100 at 10x, and the difference is the punter’s expected loss across the gap. The cap is the difference between a bonus that costs the punter tens of pounds to clear and one that costs single digits.

The free bet paid as a free bet is the cheapest welcome offer shape in the comparison. A bonus with a wagering factor is the most expensive, because the punter pays margin across the turnover. A stake-back offer on a losing acca sits between the two: the punter pays margin on the qualifying acca, and the free bet’s value is paid on the next bet, with the stake not returned.

What a £20 Qualifying Bet at 2.0 Buys

A £20 bet at decimal odds 2.0 returns £40 if it wins (stake £20 plus £20 profit). If it loses, the punter loses the £20. The free bet that follows is paid at the operator’s chosen price floor and expires in seven days. A punter who uses the free bet at 3/1 (4.00) gets £80 in profit if it wins; if it loses, the punter loses only the operator’s stake, not their own money. The expected value of the free bet depends on the market the punter uses it on, the price they take, and the operator’s margin on that market.

Why “Risk-Free” Is the Wrong Word

A “risk-free” bet is usually a stake-back offer: the operator refunds the stake as a free bet if the first bet loses. The stake is not refunded as cash, the refund is paid in the same currency the offer is marketed in (free bet, not money), and the free bet expires on the operator’s clock. A punter who reads “risk-free” as “no cost” is reading past the refund’s shape. The first bet is paid in the punter’s own money, and the free bet the punter receives is paid in the operator’s.

How to Read a Bookmaker’s Licence

The Commission’s public register is the single source of truth. A punter who wants to check a brand enters the trading name, the corporate name, the domain or the account number, and the register returns the licence, the categories it covers, the licence holder and the trading names. The Commission also lists the operating licence number and the remote licence reference, and the two together identify the brand unambiguously. The page a punter wants is the one that says “operating licence” rather than the one that says “apply for a licence” or “find a local bookmaker”.

A punter who sees a brand advertised as “licensed and regulated” without a licence number on the same page has not been given enough information. The licence number is the only string that resolves against the register. A licence that names a holding company rather than the brand is normal: a brand can sit under a parent, and several brands can sit under one parent. The Commission registers the licensee, and the licensee lists the trading names it operates.

A licence on the register does not mean an offer is good value. It means the operator has met the Commission’s licensing conditions, runs under the LCCP, takes part in GAMSTOP, applies the 10x bonus cap and accepts the Commission’s complaints route. The rest of the offer’s value is the punter’s call.

Operator Selection Notes and Trade-Offs

Matchbook is a betting exchange, and a punter who wants a daily price-boost shelf on a traditional book is in the wrong shop. Coral and Unibet run the largest daily-boost shelves, with Coral’s Shaker adding a daily free-bet element. NetBet and Kalooki carry daily boosts with narrower selections. Hollywoodbets and Betboro build the welcome offer around a single bet rather than a daily shelf. 10bet’s headline is a bonus figure rather than a daily-boost promise, and the offer’s specific shape sits in the customer terms. London Bet’s public surface is narrow. LiveScore Bet’s strongest public feature is the payment rail.

The 10x cap shapes the most expensive offers most. A punter who reads the bonus headline as the gain and ignores the wagering factor is reading past the cost. The cap is the Commission’s backstop; the punter’s arithmetic is the front line.

The seven-day expiry on most free bets is a soft pressure to bet again. A punter who lets a free bet expire has paid the qualifying stake and received nothing back. A punter who uses the free bet inside the window at a sensible price keeps the expected value.

When the Boost Costs More Than the Boost Pays

A price boost is paid for in the market the punter backs. A boost at 10/1 from a base of 6/1 is a 4-point discount on a market the operator still prices to a margin. If the punter backs a market they would not otherwise have touched, the boost is paying for a worse bet. The boost is not the gain; the bet is the bet.

The same logic applies to acca insurances. A free bet refunded on a losing acca costs the punter the acca’s margin across the qualifying stake. A punter who backs accas at 5/1 (6.00) combined is paying a margin higher than a single’s, and the insurance is a refund only on a loss. The expected value is the difference between the insurance’s refund probability and the acca’s own losing probability, and on most acca shapes that difference is small.

The 10x cap is the single biggest cost-cutting rule in this comparison. An offer that would have asked for £500 of turnover at 50x now asks for £100, and the punter’s expected loss across the gap is the cost the cap has removed.

Choosing a Bookmaker From This List

A punter who wants a wide daily-boost shelf, a Bet Builder and a Cash Out button on the same book reads Unibet or Coral first. A punter who wants a commission-free window on an exchange reads Matchbook first. A punter who backs small accas at 4/1 or higher and wants a stake-back welcome reads Hollywoodbets. A punter who wants a Bet Builder with dynamic odds and a tight welcome offer reads NetBet. A punter who backs horse racing and values Best Odds Guaranteed reads Kalooki. A punter who has been blocked from a welcome bonus by a payment-method restriction reads LiveScore Bet. A punter who wants the largest bonus figure in the comparison reads 10bet, and asks the operator’s customer support about the mixed-product shape before claiming.

The Commission’s register is the only place that resolves any licence question. The rest of the comparison is the punter’s call.

Frequently Asked Questions

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

The Gambling Commission has capped wagering requirements on bonuses at ten times the bonus amount since 19 January 2026. A £10 bonus can require no more than £100 of qualifying bets to clear, and an offer that asks a customer to gamble across two or more product types to unlock a bonus is banned. Whether the cap reaches a free bet with no wagering condition is not established in the Commission’s published rules.

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

Minimum odds set the price floor for the bets that count toward clearing the offer. A 1/2 (1.50) floor means only bets at decimal 1.50 or higher count. The wagering requirement sets how many times the bonus must be staked before it converts to withdrawable cash. Under the 10x cap, a £40 bonus needs £400 of qualifying bets at the minimum odds, and a punter who backs a market at 1.50 with a 5% margin loses about £20 of expected value across the clearing.

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

A free bet is paid in the operator’s money, not the punter’s. The operator credits the stake and pays back only the winnings. A £10 free bet at 3/1 (4.00) returns £30 in profit, not £40. This is the standard shape of British free bets and the reason a free bet’s expected value sits below the same price on a cash stake. A free bet’s stake-not-returned rule is the operator’s protection, and the punter’s edge is the price the free bet is taken at.

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

No. The Commission’s January 2026 rules ban mixed-product promotions that ask a customer to gamble on two or more product types to unlock an offer. A sports bet that earns free spins, a sports deposit that unlocks casino credit, or a casino bonus that requires a sports wager is the textbook mixed-product case the rule catches. A sports-only free bet on a sports-only market is unaffected, and a casino-only bonus on a casino-only product is unaffected.

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

The Commission’s public register can be searched by business name, trading name, domain or account number. The register returns the operating licence, the remote licence reference, the licence categories, the licence holder and the trading names. A brand that does not appear on the register, or that appears with a licence that does not cover the product it sells, is not licensed for the offer it is making in Great Britain. The register is the only test of licence status, and a licence number printed on the operator’s own site is a string to resolve against the register, not a fact in its own right.

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

The punter pays no tax on betting winnings in Great Britain. General Betting Duty is the operator’s tax, currently 15% on gross profits from general betting, with a new 25% remote betting rate scheduled from 1 April 2027. The duty is the operator’s liability, and whether any of it is passed through to customers in the form of lower odds is not established. A professional gambler should ask HMRC or an adviser, because the punter-side tax treatment of a professional’s betting income sits outside the general position. General Betting Duty, the operator’s levy to the Commission, and the punter’s tax position are three different things, and only the first two sit with the operator.
