A price boost, a Super Boost, a Daily Boost, an Uniboost, a Bet Boost, a Supercharge — every British high-street name now puts a louder version of yesterday’s odds in front of the customer. The louder version still has the bookmaker’s margin inside it, the bigger free bet unlocked beneath it still has a wagering requirement, and since 19 January 2026 the rules that price both have changed. This page walks through ten Gambling Commission-licensed operators in Great Britain running price boosts, acca boosts and free-bet welcome packages, ranks them under the cost angle a serious punter actually cares about, and works through one turnover calculation that shows what those offers are really worth.

The figures are checked as of 27 October 2026 against the Gambling Commission’s public register and each operator’s own terms. The cap on bonus wagering (10x) and the ban on mixed-product promotions took effect on 19 January 2026 under the Commission’s social responsibility code and are the rule book the rankings below measure against.

Where price boosts sit under UK law

Great Britain runs gambling under the Gambling Act 2005, with the Gambling Commission (UKGC) as the regulator for the whole commercial market. Since the Gambling (Licensing and Advertising) Act 2014 the licence is required at the point of consumption: an operator whose remote facilities are used in Britain needs a Commission licence wherever it is actually based, and a Curaçao, Maltese or Gibraltar licence does not stand in for one. There is no state monopoly and no statutory cap on the number of licences, which is why the public register runs into the thousands rather than tens.

Inside that licence the operator picks from categories: 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 a betting exchange runs on). Every brand reviewed below holds the remote general betting standard (real events) category under a remote licence matched to a Commission account number; Matchbook and Coral additionally hold the betting intermediary category on the same licence. The register is searchable by business name, trading name, domain or account number, and it is the only place that decides whether a brand is licensed to take a bet in Britain — the domain proves nothing, because licensed operators in this market commonly use .com as well as .co.uk.

Nothing in the Act names what may or may not be bet on. In-play, esports, virtual events, politics, novelty markets and accumulator bets are all permitted; what an operator offers is the operator’s own choice under its licence conditions and the Licence Conditions and Codes of Practice. A separate FCA authorisation covers financial spread betting, not sports spread betting — Spreadex, for instance, is authorised by the FCA for spread betting and separately licensed by the Commission for fixed-odds betting, and spread-betting losses on its platform can exceed what the customer paid in.

The closest Britain gets to a “what may be bet on” rule is the bonus code, and that is where the most concrete rule of 2026 sits. Since 19 January 2026 the Commission’s social responsibility code has put two ceilings in place: bonus wagering requirements are capped at 10x the bonus amount, and mixed-product promotions — an offer that ties a sportsbook free bet to casino play, or lottery entry to bingo, across the same sign-up — are banned outright. A £10 bonus at the old 50x rate needed £500 of qualifying bets; under the cap no more than £100, and the rollout since January has caught a number of headline offers mid-flight. Whether the cap catches free bets that carry no wagering condition at all is not settled by the Commission’s published guidance; what is settled is that any offer named or described as needing wagering cannot exceed 10x.

The second thing 19 January changed was the marketing frame around those offers. The Code’s marketing condition still requires bonuses to be described clearly, expiry and eligibility to be readable in plain sight, and “risk-free” language to be earned (a “risk-free” free bet, whose stake is not paid back with the winnings, is not a refund in money). That is the marketing rule that bites when an advertisement promises a “free” amount the punter cannot actually withdraw without playing through.

What a price boost is — and what it isn’t

A price boost is the bookmaker taking one market on its own site and pricing it above the price the same firm would normally quote. The headline word is “boosted”. The mechanics underneath look like a price change in a sportsbook’s trading screen: a selection that would normally be 6/4 is showing at 7/4, or a four-fold accumulator normally 9/2 is showing at 11/2. The name on the button varies — Sky Bet calls them Sky Bet Super Boosts, bet365 calls them Super Boosts, Unibet calls them Uniboosts, Coral calls them Odds Boosters, William Hill runs Daily Bet Boosts, BoyleSports runs Daily Free Bet Boosts, Kwiff calls its version Supercharge and is the only UK brand that promises an instant, after-the-fact upgrade from 2/1 to 20/1.

In every case the boost is bound by the bookmaker’s stake cap and pre-match / in-play status. The cap is rarely advertised in the marketing line and is the part the punter finds out about only when the bet is rejected at the slip — most UK books cap single boosts between £5 and £20 and run tighter caps on the busy Saturday afternoon slate. Coral’s daily Reward Shaker spins a promotional prize with a similar ceiling; William Hill caps its Football Acca Boost at a £10,000 maximum per online bet, which is generous until the punter remembers the boost is a percentage of the winnings, not a stake match.

What a price boost is not is a margin-free gift. The bookmaker’s margin sits inside the boosted price just as it sits inside the un-boosted price. A 6/4 shot boosted to 7/4 still returns a return that bakes in the firm’s overround, and on a multi-leg price boost the operator’s edge compounds leg by leg. The honest reading of a price boost is “a generous line on a market the firm has decided it wants action on today”, not “a free lunch”.

A second distinction matters: a price boost is usually paid as cash into the return, so the boosted part can be withdrawn with the win; a free bet credited as a result of an offer is paid only as the winning portion, and the stake is rarely returned. Bet365’s Winnings Boosts on Bet Builders and selected singles sit closer to the cash side; Sky Bet’s three £10 free bet tokens sit on the credit side. Conflating the two is the way a punter walks out of an offer worse off than the marketing suggested.

How a sign-up offer actually pays out

A sign-up welcome offer — Coral’s “Get £40 in Free Bets when you bet £20”, Sky Bet’s three £10 free bet tokens after a 5p first bet, Unibet’s identical-shape £40 in free bets for a £20 qualifying bet, Hollywoodbets’ stake-back free bet on a losing accumulator, BoyleSports’ £20 in free bets for a £10 bet, Betboro’s 100% matched free bet up to £25, Spreadex’s £60 free bets from a £10 fixed-odds qualifying bet, Matchbook’s 110 days of commission-free exchange betting, the SBK £60 free bets package from a Smarkets-linked sportsbook, 10bet’s 100% up to £50 betting bonus — works on the same skeleton.

Three things define the shape of every welcome package, and they are the three things a punter should write down before claiming:

• Qualifying bet. A stake the punter must place with their own money first. Coral, Unibet, Sky Bet, Hollywoodbets and Spreadex all set their own minimum at £5, £10 or £20 depending on package, with Hollywoodbets pinning the qualifying bet to an accumulator of three or more legs at 4/1 or bigger. The qualifying bet is paid in cash and, if it wins, the return is the punter’s to keep regardless of what comes next.
• Minimum odds. The shortest price the qualifying bet may be placed at. Coral sets it at 2.0 (1/1); Unibet at 2.0 (1/1); Sky Bet at 1/1 or greater, with the qualification further compressed to a 5p minimum stake; Hollywoodbets on 4/1 for the accumulator; Spreadex at 1/2; Betboro at 3/5 (1.60) and a maximum £25 first bet. The minimum odds are the price below which the wagering requirement is treated as not met, and they exist because offers priced any shorter than the floor are arbitrable against the book’s normal margin.
• Bonus or free bet credit. Coral credits £40 in free bets within 7 days, expiring 7 days after issue; Sky Bet credits three £10 tokens for use on any market; Spreadex credits £60 usable across fixed-odds and spread betting once the qualifying bet is placed within 28 days; Unibet runs the same 7-day expiry pattern as Coral; BoyleSports credits the £20 once the £10 qualifying bet has settled. A free bet typically does not return the stake on a win — the punter sees only the profit, which is what makes the calculation below land where it does.

One additional mechanism shows up on a smaller set of brands: opt-in. Welcome offers in Great Britain are opt-in rather than auto-enrolled, which is itself a Commission rule — the operator cannot quietly credit a bonus without an explicit “I want this” click. Hollywoodbets, Betboro and the others run on the same opt-in flow, with the toggle usually living in the “My Offers” tab rather than on the deposit screen.

A reward mechanism, separate from a welcome package, runs alongside the welcome bet. Coral’s daily Reward Shaker, William Hill’s Football Acca Boost (running until 30 May 2027), bet365’s daily Bet Boosts, Kwiff’s Supercharge, BoyleSports’ Acca Insurance (paid as a free bet if one leg lets down) and Acca Loyalty (paid as a free bet once five settled legs have gone in) are all reward mechanics, not sign-up bonuses. They sit on top of the welcome package and run for the life of the account.

What “free” actually costs: the working sum

A free bet paid as a free bet is the offer the marketing language most often hides behind. It looks like £40 in value; the calculation says £40 minus whatever the bookmaker’s margin would have taken had the punter bet with cash instead.

Take Coral’s £40 free bet package as the worked example. The qualifying bet is £20 at minimum odds of 2.0 (1/1), placed with cash on the sportsbook. The free bet amount is £40, split as the operator decides across the credit, with a 7-day window from issue and a 7-day stake limit on any single placement with the credit. The free bet stake is not returned on a winning bet — the punter sees only the profit at the boosted price, not the £40 returned alongside it. The number that matters is how much profit the credit produces on average, not the face value of the credit itself.

For a free bet whose stake is not returned, the average value is calculated as free-bet amount × (odds − 1) ÷ odds × payout share of the market. Take a typical Premier League match with a margin of about 5%, which gives a payout share around 95%. Place the free bet on a single at odds of 3.0 (2/1): expected value on the free bet is £40 × (3.0 − 1) ÷ 3.0 × 0.95, that is £40 × 2/3 × 0.95 ≈ £25.33. That is the average profit the £40 credit returns across many bets at that price on that kind of market.

If the punter places the free bet on a 5.0 shot the average climbs — £40 × 4/5 × 0.95 ≈ £30.40. On a 2.0 shot it drops — £40 × 1/2 × 0.95 = £19.00. Lower odds mean more of the value sits in the stake that is not returned. Higher odds mean the missing stake matters less, but the margin on long-priced markets is wider — bookmakers keep a fatter slice of 20/1 and 50/1 bets than they do of evens — so the realistic average on the wilder end pulls back from the headline.

This is the sum Coral’s £40 free bet does not put on its homepage. The free bet is worth roughly £20 to £30 in average profit depending on where it is placed, with 7 days in which to place it. Compare that with Spreadex’s £60 in free bets from a £10 qualifying bet: same shape, larger headline number, same condition that the free-bet stake is not paid back. Compare it with Sky Bet’s three £10 tokens: £30 face value, broken across three separate bets with their own minimum odds, which means the punter cannot concentrate the credit on the one price they most fancy.

For a marketing description that calls the offer “free”, the realised number on the average bet is closer to two-thirds of the face value on a typical single at evens or longer. That is the measure the rest of this page works to. A bigger headline number on a longer qualifying bet does not make a better offer if the qualifying bet itself carries a margin cost the punter pays out of pocket.

What the 19 January cap does to a bonus

Bonuses with a wagering condition are a different animal from free bets without one. A bonus is paid in cash, but the cash cannot be withdrawn until the punter has turned over the bonus (or in some packages the bonus plus deposit) a set number of times at a set minimum price. The 10x cap from 19 January 2026 is the rule that re-priced the whole British bonus market.

Before the cap a £10 bonus at 50x wagering needed £500 of qualifying bets; under the cap it cannot. A £50 bonus at 10x needs £500 of qualifying bets (the same total as the old £10-at-50x), which made the headline bonuses climb through 2025 until the bigger numbers ran into the new ceiling. The Commission’s stated rationale was that the wagering burden had drifted beyond the point where most customers ever cleared the bonus, which is the same complaint that drove the parallel ban on mixed-product promotions.

The expected cost of clearing a bonus is the part the marketing never mentions. For a bonus turnover, required turnover = bonus base × wagering factor, bets needed = turnover ÷ stake per bet, and expected cost = required turnover × margin of the market that the wagering is being placed on. Take a £50 bonus at 10x with a £5 stake per bet on a market with a 5% margin: turnover is £500; the punter needs 100 qualifying bets of £5 each; the expected cost of clearing the bonus on average is £500 × 0.05 = £25. That is half the bonus’ face value lost back to the margin before the punter sees a penny of withdrawable winnings — and that is the calculation on a brand with a normal book margin, not the wider-margin markets that bonus wagering often routes through.

That is also why the second rule matters. A £50 bonus at 10x on football singles (5% margin) is a much smaller expected loss than the same £50 bonus at 10x routed through in-play markets, exotic markets, casino, or any combination the operator can construct. The mixed-product ban, in effect since 19 January 2026, closes off the casino-reroute that older welcome packages used to fold wagering into. Betting and casino are now separate permits with separate rules, and any operator that still tries to roll slots turnover into a sportsbook bonus is in breach of the new code.

What the cap does not do is cap the value of the bonus itself. A £200 free bet package is not forbidden — only its wagering condition is. Hollywoodbets’ stake-back free bet, Spreadex’s £60 free bet, Coral’s £40 free bet, Sky Bet’s three £10 tokens all sit comfortably below the cap because they are free bets with no wagering condition rather than bonuses that need playing through. Whether the 10x cap reaches free bets with no wagering condition is not established. The Commission’s published guidance covers bonuses; free bets that carry no playthrough, no minimum-odds gate and a straightforward 7-day expiry are differently structured and have not been the subject of an enforcement bulletin on this point.

The honest framing for the punter is to read the offer as either a bonus (paid as cash, gated by wagering, capped at 10x since 19 January 2026) or a free bet (paid as credit, stake not returned, usually no wagering, expiry 7 days). They look similar in the marketing line and they cost the punter very differently.

The ranking, ranked on what the offer costs

The table below takes the ten Gambling Commission-licensed operators running price boosts and sign-up packages and lines them up by what those offers actually pay out. The column layout treats every brand equally: licence status, the shape of the welcome package as each operator’s own terms describe it, and where the head-to-head breaks. No column is a recommendation column — the closer reading sits in the operator notes that follow.

A few reading points worth holding onto. Coral and Unibet run the same shape of welcome package (bet £20, get £40 in free bets, minimum odds 2.0, 7-day expiry, debit card or instant bank transfer qualification) and split the difference on which one runs the better daily boosts underneath. Sky Bet’s package looks modest against Coral on face value but the qualifying bet is 5p — a price that turns the offer into a low-stake welcome with a £30 free bet ceiling rather than the £40 ceiling Coral offers for a £20 cash outlay. Hollywoodbets runs the rarer stake-back-on-a-losing-accumulative shape — the welcome pays on a loss, not a win — and ties it to accumulator qualification at 4/1, which is a sharply higher bar than Coral’s 2.0. Spreadex advertises the largest single free-bet pot in the set at £60, but it is the same shape of free bet as the others: stake not returned, expiry 28 days from when the qualifying bet was placed (rather than from the credit, as Coral’s is). Matchbook sits on a different kind of welcome — commission-free exchange betting for 110 days from registration — and is rated against the same comparison column not because the offer is identical to Coral’s, but because a price-boost-conscious punter comparing welcome packages should know which one trades welcome-bet value for exchange economics.

The brands not appearing in the rank — Midnite, Kwiff, LiveScore Bet, Star Sports, bet365, William Hill, BetVictor, NetBet Sport, London Bet, DAZN Bet, QuinnBet, Kalooki Sportsbook, Kalooki in the second row — are not absent from the licensed list. They are either not the focus of this comparison (some are casino-led and run sportsbook as a secondary product) or are reserved for the operator notes beneath this table. Where they touch the price-boost conversation specifically, they come in through the notes below and through the responsibility and payment coverage further down.

Coral — the daily boost anchor with the headline welcome

Coral sits in the centre of any UK price-boost comparison. The welcome package is the workhorse: bet £20, get £40 in free bets, minimum odds 2.0, debit card or instant bank transfer qualification, free bets credited within 7 days and expiring 7 days after issue. The marketing is clear, the qualifying bet is a normal sportsbook stake, and the floor price is not set so high that only exotic markets qualify.

Underneath the welcome sits the daily offer. Coral’s Odds Booster runs across hundreds of markets, with a free daily Reward Shaker spinning promotional prizes on opt-in. The Reward Shaker is a free-to-play game that credits free bets, free spins or jackpot entries depending on the day’s draw; the Odds Booster is a hard price boost on selected markets with a small maximum stake. Coral’s Football Super Series is a separate free-to-play product with a £10,000 jackpot. Payment coverage is wide: Apple Pay, Visa, Visa Electron, Mastercard, Revolut Pay, Google Pay, TrueLayer, Earthport and Trustly. The licence is held by LC International Limited, also the licensee of Ladbrokes — both brands sit under one licence, which a punter can confirm on the Commission’s public register.

The verdict on Coral is that the welcome shape is what every other UK bookmaker is benchmarked against, and the daily boost machinery is the most consistently distributed across markets. The £40 free bet ceiling is meaningful, the 7-day expiry is the standard, and the payment coverage makes the qualifying bet the easiest part of the package to land.

Unibet — best odds guaranteed, Uniboosts, the long-established welcome

Unibet’s UK site is run by Platinum Gaming Limited, Gibraltar, under Gambling Commission account 45322; the parent brand has operated since 1999 and Unibet’s British licence has been continuous since the early days of the post-2014 point-of-consumption regime. The welcome package runs on the same £40 free bet for a £20 qualifying bet skeleton as Coral, with the same minimum odds of 2.0 (1/1), the same 7-day free-bet expiry and the same debit card or instant bank transfer qualification. Where Unibet stretches further than Coral is on the live product: Uniboosts run daily, the acca builder is a same-game multi, Best Odds Guaranteed on horse racing pays the larger of the SP and the price taken, and Unibet TV streams thousands of live events each year. Cash Out is on thousands of markets.

The verdict on Unibet is that it offers the same welcome package as Coral with a wider live product behind it; the differentiating feature is the broadcast, the best-odds-guaranteed horse racing and the in-play depth, which a punter who wants to use a free bet on a Saturday afternoon football slate will actually feel.

Sky Bet — the 5p-qualifying welcome that pulls in the small-stake punter

Sky Bet’s welcome is unusual. The package is £30 in free bets, credited as three £10 free bet tokens after a deposit of at least £5 and a first single or each-way bet of at least 5p at odds of 1/1 or greater. Three tokens is a hard ceiling on the welcome value compared to Coral’s £40, but the 5p qualifying bet flattens the entry cost to almost nothing. A punter with £5 in their account and 5p to stake on any selection at 1/1 or longer will trigger the welcome package; the three tokens can be spent on any market at any qualifying price, with the usual 30-day expiry on Sky Bet free bets.

Sky Bet is also one of the British books running enhanced-price welcome offers — a one-shot bigger price for new customers on a named football or racing market, paid as cash into the return with no wagering condition. The Super Boosts, the Super 6 free-to-play game and the Sky Sports-adjacent marketing push make the brand a high-traffic choice.

The verdict on Sky Bet is that the welcome is best suited to a small-stake punter who wants the welcome package without committing £20 to a qualifying bet at the Coral bar; the £30 ceiling is honest about its size, and the three-token structure forces three separate bets rather than the one big free bet a Coral-shaped welcome allows.

Hollywoodbets — the stake-back on a losing acca

Hollywoodbets is the rarer shape in this comparison. The welcome offer is a free bet of up to £30 paid on a losing first qualifying accumulator — three or more legs, minimum odds of 4/1, settled within 7 days of placement, with one free bet per customer. The qualifying bet is paid as cash; if the accumulator wins, the punter keeps the cash return and the welcome is over. If the accumulator loses, Hollywoodbets refunds the qualifying stake as a free bet, up to £30.

The 4/1 floor for the accumulator and the 3-leg minimum are sharper than the Coral welcome’s 2.0 floor on a single. A punter who would otherwise bet on a same-game multi or a longer-odds acca anyway is the natural customer for this offer; a punter looking for a generic £20 qualifying bet on a single is not.

The verdict on Hollywoodbets is that the offer flips the standard shape — Coral pays on a win, Hollywoodbets pays on a loss — and pins that to a sharper price and longer acca, which makes the offer good value for the punter whose natural bet is a four-leg football acca at the weekend and wasted value for the punter whose natural bet is a single.

Spreadex — the fixed-odds welcome with spread-betting depth

Spreadex is one of the few dual-authorised names on the comparison. FCA-regulated for spread betting, Gambling Commission-regulated for fixed-odds betting. Spread betting on Spreadex can lose more than the deposit, which is a different shape of risk from the fixed-odds welcome package. The fixed-odds welcome is £60 in free bets for a £10 fixed-odds bet, with a qualifying bet at minimum odds of 1/2 and a 28-day window from account opening for the qualifying bet. The free bets are usable across fixed-odds and spread betting markets, and the qualifying bet must be placed in the first 28 days.

Underneath the welcome sits Spreadex’s Acca Boosts, a cash boost from 5% (on three selections) up to 100% on longer football accumulators, paid on the winning return. The cash boost sits closer to a price boost than the credit-style free bets Coral and Hollywoodbets run.

The verdict on Spreadex is that the largest single welcome pot in the comparison (£60 free bets for a £10 qualifying bet) runs alongside a sharp reminder that spread betting on the same platform is a different product — high-leverage, FCA-supervised, and capable of returning a loss that exceeds the deposit.

BoyleSports — the £10 qualifying bet, two markets in one app

BoyleSports runs a UK welcome of £20 in free bets for a £10 bet (with a parallel €30 free-bet package for Irish players). The qualifying bet shape is the simplest in this comparison: a £10 cash bet at minimum odds that the operator does not pin to a sharp bar, with the £20 credit landing on settlement. BoyleSports also runs Acca Insurance (a free bet if one leg of a qualifying acca lets down, max refund £20, min stake £5, min odds 1/2, settled on the same day) and Acca Loyalty (a free bet once 5+ qualifying legs at combined odds of 3/1 have settled, min stake £5). The Acca Insurance and Acca Loyalty packages are paid as free bets expiring after 7 days.

The verdict on BoyleSports is that the £10 qualifying bet and the £20 free bet make this the lowest-friction welcome package in the comparison, and the Acca Insurance + Loyalty combo is a deeper reward structure than most rivals run.

Betboro — the matched free bet that pins to a minimum legs floor

Betboro’s welcome is a 100% matched free bet of up to £25, requiring a debit card deposit of at least £10 and a first bet of £5 to £25 with at least three selections each at 3/5 (1.60) or higher. The free bet is matched to the qualifying stake, capped at £25, paid as a free bet rather than as cash. The three-selection minimum and the 1.60 floor on each selection push the qualifying bet toward an accumulator rather than a single.

The verdict on Betboro is that the matched-free-bet shape is rarer than a fixed free-bet credit, and the three-leg minimum prices this welcome above Coral for the punter whose natural bet is a short-odds treble.

10bet — the 100% bonus and the daily free-bet wrapper

10bet’s UK offer runs as a 100% up to £50 betting bonus alongside daily free bets and free spins. The bonus is a betting bonus rather than a fixed free-bet credit, which means wagering conditions apply in the operator’s own terms. Under the 19 January 2026 cap any wagering condition cannot exceed 10x the bonus; the operator’s own terms carry the exact minimum odds, expiry and qualifying market.

The verdict on 10bet is that the headline figure is the largest 100% bonus in the comparison, but the marketing is the bonus side of the free-bet-versus-bonus split rather than the cleaner free-bet credit Coral and Hollywoodbets run. The punter should read the wagering condition in the operator’s terms before claiming.

Matchbook — the exchange welcome that is not a free bet

Matchbook is a betting exchange, not a traditional sportsbook. The welcome is 110 days of commission-free betting from registration, refundable against the customer’s first deposit, with the operator’s standard commission applying after the 110 days are out. The promotion is opt-in and requires a deposit at registration.

For a price-boost comparison Matchbook is the outlier: the value sits in the exchange commission discount rather than in a free-bet credit. The Commission’s gambling intermediary licence category is what makes Matchbook’s offer legal in Great Britain — remote betting intermediary (real events) sits on the same licence as the standard betting categories. The punter who would otherwise have paid Matchbook’s standard commission rate on lay bets and on the back side of the bets they match pays zero for the first 110 days.

The verdict on Matchbook is that this is the welcome for the punter who already bets on exchanges and wants a four-month window without commission; the price-boost comparison above treats it as a different shape of offer rather than as a smaller version of Coral.

SBK — the Smarkets-linked sportsbook that mirrors the exchange parent

SBK is the sportsbook sister of Smarkets. The UK welcome is £20 first deposit and £20 bet at minimum odds of 3.0 for £60 in free bets within 48 hours of settlement, with Cash Out, Bet Builder and live horse racing streams included in the app. The SBK licence sits on the public register as a remote general betting standard (real events) operator under a Smarkets-linked licensee.

The verdict on SBK is that this is the cross-over welcome — a sportsbook offer on top of an exchange parent — and the £60 free bet ceiling is one of the larger in the comparison, with a 3.0 minimum odds floor on the qualifying bet higher than Coral’s 2.0.

The other licensed brands in the comparison

A serious price-boost comparison does not stop at the ten welcome packages above. The Commission’s register lists licensed brands running their own daily boosts, and four are worth pulling into the discussion even though they are not the headline comparison.

bet365 runs the largest daily boost catalogue in the British market: Super Boosts, Winnings Boosts on Bet Builders and selected singles, daily Bet Boosts and the in-play version of the same machinery on selected markets. Bet Builder+ combines markets from one event into a single bet, available pre-match and in-play. The welcome on bet365’s UK app is a Bet £10 Get £30 in Free Bets package, with the cash returns paid into the punter’s withdrawable balance.

William Hill runs the Football Acca Boost across accas of two or more legs at minimum odds of 1/5 per leg, with boosts from 3% on a double to 200% on 20+ legs and a maximum boost of £10,000 per online bet. The promotion runs until 30 May 2027. William Hill’s daily Bet Boosts and enhanced odds sit alongside the Acca Boost as the brand’s price-boost machinery.

Kwiff runs Supercharge, the only price-boost feature in the British market that promises an instant upgrade from 2/1 to 20/1 on a bet the punter has already placed — the boost lands after the bet is struck, not before. Kwiff also runs Bet Builder and Bet Builder+ (the latter combining Bet Builder bets across different games) and a guaranteed weekend acca boost.

Kalooki Sportsbook is the newer entrant. Operated by Kalooki Sports Book Ltd (company number 12938274), licensed by the Commission under account 57730, 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 welcome on Kalooki’s UK site is a stake-back free bet for a losing first qualifying bet, paid as a credit.

Midnite — Commission account 101839 — runs an in-play catalogue with an acca builder, popular accas and price boosts with maximum-stake limits visible in the app. Star Sports runs pre-event and in-play markets with Bet Boosts, Daily Specials and Weekend Enhanced Boosts. DAZN Bet offers Cash Out, Bet Builder, daily bet boosts and in-play betting, with the explicit caveat that cash-out availability is not guaranteed. NetBet Sport runs Daily Boosts, Profit Boosts and free-bet offers with a Bet Builder that shows instant dynamic odds. QuinnBet credits free bets valid for 7 days at minimum odds of 1/2 (1.5) and maximum odds of 50/1, with straight accumulators allowed but Trixies, Patents and Yankees excluded. London Bet is published by Thistle Bet Limited and runs as a smaller-scale licensed sportsbook with a 17+ App Store age rating. LiveScore Bet accepts debit cards (Visa and Mastercard), Apple Pay, PayPal, Pay by Bank (Open Banking) and Revolut Pay.

None of these brands are the head of the comparison because their welcome packages do not dominate on cost, but they are the wider context the comparison is honest about. A price-boost punter comparing Coral against Unibet against Hollywoodbets should also know that bet365’s Super Boost catalogue is the largest daily distribution and that Kwiff’s Supercharge is the only post-strike boost in the British market.

How payments shape the qualifying bet

The credit-card ban on gambling in Great Britain (in force since 14 April 2020, LCCP condition 6.1.2) closes one route and forces every welcome package to qualify through debit cards, bank transfers, e-wallets or instant bank payments. Coral and Unibet both pin the £20 qualifying bet to a debit card or instant bank transfer, which means a punter depositing via PayPal or Revolut Pay will see the welcome package locked out until the qualifying deposit lands through the right rail. LiveScore Bet takes debit cards, Apple Pay, PayPal, Pay by Bank and Revolut Pay, which is a wider payment coverage than most rivals and means no payment-method gap for LiveScore Bet’s own offers.

The Practical Payments Holding Pen: where the operator’s welcome terms tie the qualifying deposit to a specific payment rail, claim the offer with that rail on the first deposit. A £20 PayPal deposit at Coral will not trigger Coral’s welcome; the same £20 debit-card deposit will. There is no API that fixes this on the punter’s behalf; the qualifying payment rail is a checkbox on the deposit page, not on the operator’s terms page, and missing it is the most common reason a welcome package does not credit.

For withdrawals the licensed operators run a different timing. Kalooki advertises instant withdrawals by bank transfer within minutes; the bigger names settle withdrawals between four hours and a couple of working days depending on the rail. The Commission’s identity-verification rule, in force since 7 May 2019 and now part of the standard onboarding flow, requires a name, address and date-of-birth check before the first deposit is placed, with a free bet or bonus also covered by that check. A licensed site is not anonymous, even on the welcome package.

Better Gambling tools that come with the licence

A Gambling Commission remote licence is not just a permission to take bets in Britain. It carries the safer-gambling duties under the Licence Conditions and Codes of Practice, and the practical effect for the punter is a set of tools that an unlicensed site does not have to offer.

GAMSTOP is the national multi-operator online self-exclusion scheme, free at the point of use, mandatory for every online licensee since 31 March 2020. Self-exclusion periods are six months, one year, five years, or five years with auto-renewal, and after the minimum period the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to lift it. GAMSTOP covers online sites and apps only — betting shops run a separate service. A punter excluded from one licensed brand is excluded from all of them.

Deposit limits are mandatory for online licensees under the Remote Technical Standards (RTS 12). The first changes applied on 31 October 2025, a second phase was postponed to 30 September 2026, and the live status of phase two is not settled by the public record. Operators offer deposit limits on a fixed time frame (daily, weekly, monthly), with the customer’s choice the binding ceiling. There is no state-set deposit or loss ceiling for betting: the operator’s tools are the customer’s choice, taken at a level the customer sets.

A financial vulnerability check runs under LCCP condition 3.4.4 (in force 30 August 2024) when a customer’s deposits minus withdrawals exceed £150 in a rolling 30 days (the threshold has applied since 28 February 2025). The check is a public-record check — bankruptcy, county court judgments, IVA — and is not an income check or a credit-reference check. This is the cheapest of the customer-protection layers and the one most licensed brands will not draw attention to in the marketing.

A financial risk assessment sits above the vulnerability check as a fuller affordability review. The Commission’s staged plan for these was published on 7 July 2026 with no start date, and the live status remains “announced, staged, no start date”. When these come in they will replace the press shorthand “affordability checks”; for now the vulnerability check is what is in force.

Help. GamCare runs the National Gambling Helpline. GambleAware signposts self-help and treatment. The NHS runs gambling clinics in several regions. Gamblers Anonymous runs in-person meetings. Every licensed brand listed above has safer-gambling information on its app and links out to GamCare and GAMSTOP. A punter using an unlicensed site has none of these protections, and the practical difference is that a dispute on winnings, a withdrawal stop-payment or a self-exclusion breach has no Commission complaints route, no approved dispute-resolution service and no British consumer redress.

Tax, exchange-rate and offshore reminders

Betting winnings in Great Britain are not taxed on the punter’s side. General Betting Duty is the operator’s tax on gross profits at 15%, with a remote betting rate of 25% from 1 April 2027 within that duty for remote bets outside UK horse racing, self-service betting terminals and pool/in-person betting. Until 1 April 2027 the remote rate stays at 15%; whether operators pass duty on through odds is not established and the punter is never charged duty directly. Spread betting has its own rates (3% financial, 10% other). This page is general information, not tax advice; a professional gambler should ask HMRC or an adviser.

Offshore is the parallel set of brands licensed outside the British point-of-consumption regime. The Commission’s enforcement is disruption rather than blocking: cease-and-desist notices, search-engine referrals, registrar work and a planned court-order DNS-blocking power that is not yet in operation. A punt on an unlicensed site is not, on the customer’s side, the offence the Act creates; the Act targets the operator. A customer using an unlicensed site loses GAMSTOP coverage, the Commission complaints route, the approved dispute-resolution body and any British consumer redress; the bonus cap does not apply; the £150 vulnerability check does not apply. Honest framing: licensed is checks, limits, GAMSTOP, the bonus cap — and identity verification before the first bet; unlicensed is none of those, with the possibility of funds being hard to recover. Neither is “the safe choice” by default.

Putting the operators alongside each other

Head-to-head, the offer the punter should know about is not the highest headline. Coral’s £40 free bet for a £20 qualifying bet at 2.0 minimum odds is the workhorse — generous on face, clean in the terms, and matched by a wide payment coverage. Unibet runs the same shape but stretches it further on the live product, the Best Odds Guaranteed on racing and the broadcast. Sky Bet pulls in the small-stake punter with a 5p qualifying bet and a £30 three-token ceiling. Hollywoodbets re-shapes the welcome onto the accumulator with a 4/1 floor and three legs minimum. Spreadex runs the largest single free-bet ceiling in the comparison (£60 for a £10 qualifying bet) but asks the punter to deposit within 28 days, with a spread-betting product underneath that does not look like the fixed-odds welcome. BoyleSports runs a £10-to-£20 welcome with the cleanest qualifying shape and a deeper Acca Insurance + Loyalty structure. Betboro matches the qualifying stake up to £25, with a three-leg floor on each selection at 1.60. 10bet runs the largest 100% bonus headline but on the bonus side of the free-bet-versus-bonus split. Matchbook is the exchange welcome on commission-free betting for 110 days. SBK runs a £60 free-bet ceiling for a £20 qualifying bet at 3.0.

Outside the ranking, bet365 runs the largest Super Boost / Winnings Boost / daily Bet Boost catalogue and the welcome is a Bet £10 Get £30 in Free Bets package. William Hill runs the Football Acca Boost until 30 May 2027 with boosts from 3% on a double to 200% on 20+ legs and a £10,000 maximum boost. Kwiff is the only post-strike boost (Supercharge) on the British market. Kalooki Sportsbook is the newer entrant with instant withdrawals by bank transfer and a stake-back free bet on the first losing qualifying bet. Midnite, Star Sports, DAZN Bet, NetBet Sport, QuinnBet, London Bet and LiveScore Bet are the wider licensed set with their own boost machinery, payment coverage and smaller welcome packages.

The angle this page works to is cost — what this costs the punter — and the close of the ranking is the same. The cheapest welcome to clear on average is the one whose qualifying bet sits on a market with a thin margin, whose free bet expiry is wide enough to find a 2.0+ price on, and whose wagering condition sits below the cap. Coral, Unibet and BoyleSports sit closest to that shape. bet365, William Hill and Kwiff cover the punter whose natural bet is the daily boost catalogue rather than the welcome package. Hollywoodbets and Spreadex cover the punter who likes a sharper price or the larger single pot.

Bonus turnover: a worked example under the 10x cap

Take 10bet’s “100% up to £50 betting bonus” as the headline number, and apply the 10x cap that has been in force since 19 January 2026. The bonus base is £50 (the matched amount), the wagering factor is 10x, the stake per bet is £5, and the minimum odds are whatever 10bet’s terms name for a sportsbook wagering market. Run the formula:

Turnover = bonus × wagering factor = £50 × 10 = £500.

Bets needed = turnover ÷ stake per bet = £500 ÷ £5 = 100 qualifying bets at minimum odds or longer.

Expected cost = turnover × margin of the market. A pre-match football single on a major league sits at a margin of about 5% on most British books; an in-play market sits wider at 6% to 8%; an exotic market sits at 8% to 12%. On 5% margin the expected cost of clearing the £50 bonus is £500 × 0.05 = £25. On 8% margin it is £500 × 0.08 = £40. On the wider exotics it is £500 × 0.10 = £50.

Stated as the band the page commits to: clearing a £50 bonus under the 10x cap costs the punter, on average across many bets and many markets, between £25 and £50 of expected margin before the bonus face value is realised. The lower end of that band is what a careful punter who pins the wagering to pre-match major-market singles can land; the upper end is what a punter who lets the wagering drift across in-play and exotic markets will pay. The wagering cap takes 50x to 10x and brings the headline bonus into line, but it does not cancel the cost — it moves the cost into a smaller, but still meaningful, margin loss. That is the working sum under the new rules: the wagering cap tightens, and what is left for the punter is to keep the qualifying bets on markets thin enough that the margin does not eat the bonus.

The calculation is a statistical estimate: the £25-to-£50 expected cost is the average over many bets under the conditions named, not a guarantee for any single £50 bonus cleared on any single series of bets.

What this costs the punter in plain sentences

The offer on Coral, Unibet, Hollywoodbets, Sky Bet, Spreadex, BoyleSports, Betboro, 10bet, Matchbook and SBK can be summarised in three lines a punter can carry in their head.

The free-bet welcome on Coral, Unibet, Hollywoodbets, Sky Bet, Spreadex, BoyleSports, Betboro and SBK pays roughly two-thirds of the face value of the credit on average, because the stake is not returned and the margin on the average market takes another slice. £40 in free bets is worth about £24 to £30 in average profit; £60 is worth about £40 to £45; £30 split into three tokens forces three separate bets, each one shorter on average than a single consolidated credit.

The 10x bonus cap that has been in force since 19 January 2026 makes every bonus cheaper to clear than the 2024 shape, but it does not make the bonus free. A £50 bonus at 10x requires £500 of qualifying bets, which carries an expected margin cost of £25 to £50 depending on the market the wagering is being placed on. The mixed-product ban that came in at the same time closes the casino route, which is what the older 50x offers used to lean on.

The price boost in the daily catalogue — Sky Bet’s Super Boosts, bet365’s Super Boosts and Bet Boosts, Unibet’s Uniboosts, Coral’s Odds Boosters, William Hill’s Football Acca Boost, BoyleSports’ Daily Boosts, Kwiff’s Supercharge — is a marketing word for the bookmaker’s choice of which market it wants action on today. The boosted price still carries the firm’s margin; the stake cap is rarely advertised at the headline; the expiry on a free bet unlocked by the boost is the operator’s standard 7 days.

That is the cost. A price-boost-conscious punter’s net is the headline value of the welcome package minus the qualifying bet’s expected margin cost, minus the free-bet’s stake-not-returned haircut, minus the price boost’s stake cap. The table above is the headline-by-headline view; the worked sum on the Coral welcome and the bonus-turnover sum on the 10bet 100% bonus are the two figures that put the cost in numbers.

Frequently Asked Questions

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

The Gambling Commission’s social responsibility code, in force since 19 January 2026, caps bonus wagering requirements at 10x the bonus base. Before that date the market ran as high as 50x on headline welcome packages; under the cap no operator may require more than £100 of qualifying bets for every £10 of bonus. The cap does not, on the public record, reach free bets with no wagering condition — those sit outside the wagering definition.

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

Minimum odds are the shortest price the qualifying bet must be placed at for the welcome package to credit — Coral sets the floor at 2.0 (1/1), Hollywoodbets at 4/1 on the accumulator leg, Spreadex at 1/2, Sky Bet at 1/1 on a 5p minimum stake. The wagering requirement is how many times the bonus (or bonus plus deposit) must be staked before the bonus is withdrawable. On a £50 bonus with a 10x wagering the punter needs £500 of qualifying bets at or above the minimum odds.

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

A free bet is credited by the operator as a stake credit, not as a cash deposit, and the operator’s terms treat the stake as the firm’s money throughout the bet. On a winning bet the firm pays only the profit at the boosted price; the stake is consumed by the bet. The average value of a free bet is therefore the face value multiplied by (odds − 1) ÷ odds multiplied by the market’s payout share — for Coral’s £40 free bet at odds of 3.0 on a market with a 5% margin, that is about £25.33 in expected profit, not £40.

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

No. The same 19 January 2026 code that capped wagering at 10x also banned mixed-product promotions — an offer that requires gambling on two or more product types such as sportsbook and casino. A welcome package that bundled a sportsbook free bet with casino free spins would no longer be compliant. Sportsbook bonuses and casino bonuses are now separate permits with separate rules, and any operator still bundling the two is in breach.

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 it is the only place a licence can be confirmed. Each operator above is listed with its remote licence number (for example Coral at 054743-R-330863-014 under LC International Limited; Unibet at 045322-R-324275-019 under Platinum Gaming Limited; Hollywoodbets at 053028-R-330019-013 under Hollywoodbets International UK Limited). The domain itself proves nothing, because licensed operators use .com as well as .co.uk; only the register entry confirms the licence.

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 on gross profits and is not charged to the customer. The duty sits at 15% under the current regime, with a 25% remote betting rate within the duty from 1 April 2027 on remote bets outside UK horse racing, self-service betting terminals and pool/in-person betting. A professional gambler should ask HMRC or an adviser, because that is general information not tax advice.
