A betting site in Great Britain does not compete on whether it has a licence. Every brand worth looking at holds one, and the public register at the Gambling Commission is the only test. It competes on what the licence lets it do, on what its own terms charge the punter, and on how the offer collapses once you read past the headline. That is the comparison worth doing.

This page works through the costs. Statutory costs, structural costs, the cost of a bonus you have to clear, the cost a margin hides in the odds, the cost paid by anyone who thinks a cheaper headline number is the cheaper bookmaker. The featured set comprises ten GB-licensed operators; the judgements on each are written from what the brands themselves publish.

The figures and licence references below were checked against the Gambling Commission’s public register and the brands’ own terms pages on 27 October 2026.

Statute: the UK licence, the law that needs one, and what it actually changes

A remote bookmaker serving customers in Great Britain needs a Gambling Commission licence wherever it is incorporated. The Gambling (Licensing and Advertising) Act 2014 closed the “white-list” route: a Malta or Curaçao licence stopped being enough the moment the operator’s website or app became reachable from a British address. Sections 33 and 36 of the Gambling Act 2005, as amended, set the criminal frame; the section 33 offence is the one aimed at the operator, carrying up to 51 weeks’ imprisonment, a level-5 fine, or both on summary conviction (six months in Scotland). No offence aimed at a customer who places a bet on an unlicensed site was found in the framework. The frame stops the operator; it does not prosecute the punter.

What the licence buys is not safety in the marketing sense. It is a defined set of duties the operator has to perform: age verification from the first interaction, identity checks before a deposit is accepted, a public-record financial vulnerability check once the customer’s net deposits cross £150 in a rolling 30 days, GAMSTOP coverage, a 10x ceiling on bonus wagering requirements, and access to approved dispute resolution if a payout is withheld. None of these is optional, and the Commission’s compliance teams can and do enforce them. A brand that fails the register, or that operates under a foreign licence while taking British custom, gives the customer none of that and exposes the operator to the section 33 action. The honest framing: a GB licence means the operator has consented to a specific list of consumer-protection duties, and a customer can hold the operator to those duties if something goes wrong.

The licensing categories matter because they are what determine which markets a site can offer. The five that show up in the public register for sports betting are: remote general betting standard (real events), remote general betting standard (virtual events), remote general betting limited, remote pool betting, and remote betting intermediary. The exchange category is the last one — that is the licence a betting exchange runs under, and the rules for an exchange (back and lay, commission on net winnings, no bookmaker margin) are different from the rules for a fixed-odds bookmaker. A single licensee can hold several categories and run several brands from them. Paddy Power and Betfair share a parent. Ladbrokes and Coral share a parent. Each brand on the register is a trading name, not an independent operator, and a comparison that lists them as competitors is half-true at best.

Northern Ireland is outside the Gambling Act 2005. A GB-licensed operator does not, by holding a Commission licence, become licensed to take bets in Northern Ireland. Most of the brands below do not serve Northern Ireland at all; a few hold additional cover. The frame for Northern Ireland is the older Betting, Gaming, Lotteries and Amusements (Northern Ireland) Order 1985, and the operator that crosses the Irish Sea has to clear both regimes. None of the featured operators is licensed for Northern Ireland unless the brand’s own page says so.

Player protection: what the licence makes the operator do

A bookmaker is licensed, not safe. The duties the licence imposes are the only ones a customer can rely on, and they are worth taking one at a time.

Age 18 is the floor, not a guideline. The LCCP makes age verification a condition of the licence, and the customer journey for a GB-licensed site is built around catching under-18s at registration. A site that does not check, or that lets a minor register with a parent’s card, is breaking its licence conditions.

Identity and address checks happen before the first deposit. The Commission tightened these in May 2019, and they are not optional even when the deposit is small, the bonus is “free”, or the wagering requirement is zero. A site that asks for a driving licence and a recent utility bill before letting a customer stake £5 is not being difficult; it is meeting a condition the licence imposes. The check covers free bets and bonus credits: a free bet is a stake, and a stake is gambling, and gambling requires an identified customer.

GAMSTOP is the national multi-operator self-exclusion register and a mandatory licence condition for online operators since 31 March 2020. The customer registers once, picks a period (six months, one year, five years, or five years with auto-renewal), and every GB-licensed online operator is bound to refuse that customer’s account. After the minimum period the exclusion stays in force for a further seven years unless the customer lifts it directly with GAMSTOP. Betting shops run a separate in-shop scheme; GAMSTOP itself does not cover them.

Financial vulnerability checks. From 30 August 2024 the LCCP requires operators to run a public-record check on customers whose net deposits exceed £150 in a rolling 30 days. The check looks at county court judgments, bankruptcies and similar public markers; it is not a credit reference check, it is not an income check, and it is not a “can you afford to bet” interview. The fuller financial risk assessments, sometimes called affordability checks in the press, are announced in a staged plan (Commission article of 7 July 2026) and have no start date. The honest read: the £150 public-record check is in force, the deeper affordability interview is not yet, and the press coverage that talks about “affordability checks” ahead of a stated date is overreaching.

Deposit limits are a customer-set tool, not a state-set ceiling. The Commission’s Remote Technical Standards require operators to offer a gross deposit limit over a fixed time window. The first changes applied on 31 October 2025; a second phase was postponed to 30 September 2026. There is no state-set ceiling on a single deposit or a single loss, and the limits that show up on a betting site are the customer’s own choice.

The bonus cap. From 19 January 2026, wagering requirements on bonuses are capped at 10x the bonus amount. A £10 bonus with a 50x requirement needs £500 of qualifying bets to clear; under the cap, the same £10 bonus cannot require more than £100 of qualifying bets. The cap does not cover free bets with no wagering condition, and it does not set a money ceiling on the bonus itself — it caps the multiplier, not the headline. Mixed-product promotions are banned: an offer that requires the customer to bet on football to get free spins on a slot is no longer licensable.

Winnings from betting are not taxed on the player. General Betting Duty is the operator’s tax on gross profits, currently 15% across most categories, with a new 25% rate applying to remote bets from 1 April 2027 while pool betting, in-shop terminal bets and remote bets on UK horse racing stay at 15%. The duty is the operator’s bill. Whether the operator passes it on through tighter odds is an open question: research did not establish that operators systematically lower payouts in response, and no comparison should claim they do without the data. The player’s winnings, in any case, are paid gross.

What the licence does not do. The licence does not guarantee a payout. The licence does not guarantee competitive odds. The licence does not guarantee that a customer will like the app, that the markets will be deep, or that the in-play offering will be broad. The licence is a floor, and the comparison above the floor is the comparison the rest of this page does.

Bonuses and free bets: the cost of the headline number

The betting industry’s marketing language is built around giving things away. None of it is free in the sense a customer means by the word. Every welcome offer, every price boost, every free-bet token carries a cost the headline does not show, and the cost lives in the small print, the wagering requirement, the minimum odds, the deadline and the cap on winnings. A comparison that ranks welcome offers by headline amount is comparing numbers that mean different things. The comparison that matters is offer-for-offer on the same arithmetic.

The structural categories. A cash bonus is bonus money added to the account, withdrawable only after the wagering requirement is met; a free bet is a token that pays the winnings of a successful wager but not the stake itself; a stake-back offer refunds a losing first bet as a free bet of equal or capped value; a price boost raises the odds on a specific outcome; an accumulator insurance refunds the stake as a free bet if one leg of a multi lets the punter down; a cashback offer returns a share of net losses over a period. Each of these works differently. The free bet, because the stake is not returned, is worth less than its face value on average; a 5/1 free bet of £10 returns £60 if it wins (£50 profit) and £0 if it loses, with an expected return that depends on the market margin. The point that travels to every offer is the same: the headline is the entry price, not the value.

The 10x cap. The 19 January 2026 rule changes the calculation. A bonus that demanded 50x the bonus in qualifying bets is no longer licensable; a 40x offer is no longer licensable. The ceiling is 10x, and that puts a hard floor under the cheapest reasonable clear. A £10 bonus with a 10x cap requires £100 of qualifying bets; a £50 bonus requires £500; a £100 bonus requires £1,000. None of that is small, and the time the bonus sits in an account while the customer churns through the volume is the cost the marketing never names.

Free bet expiry. The standard expiry on a GB-licensed free bet is seven days from issue; the longer expiries exist but are not the norm. Seven days is tight on a sport with a quiet fixture list, looser on football. The offer that gives the customer three weeks is friendlier than the one that gives them a week, and the difference is real money in expected terms.

The cap on free-bet winnings. A free bet that pays winnings up to a cap is a worse offer than a free bet that pays them uncapped, all else equal. A £10 free bet on a 10/1 winner with a £100 winnings cap pays £100; a £10 free bet on a 10/1 winner uncapped pays £110. The cap is the kind of clause a comparison misses unless it is being read for, and it is the kind of clause a customer misses unless they read the small print.

The minimum odds. A bonus or free bet that requires the qualifying bet to be at minimum odds of 1/2 (1.50 decimal) clears faster than one that requires 4/1 (5.00), and faster still than one that requires 10/1 (11.00). The minimum odds are the part of the offer that decides whether the customer is realistically going to clear it, and they are the part of the offer the marketing image usually omits.

A live example. Hollywoodbets’ sports welcome offer returns a first losing accumulator of £10+ with three or more legs at minimum odds of 4/1 as a free bet up to £30, settled within seven days, one free bet per customer. The 4/1 floor is the meaningful number. At 4/1 the cumulative probability of three legs all landing is small; the offer is a stake-back, not a typical free-bet-with-bonus, and the realistic outcome is that the customer either wins (no free bet) or loses (free bet, which is not free because its stake is not returned on a win). BoyleSports’ £20-in-free-bets for a £10 bet has the same structure, and the £20 is not £20 of value; it is a free-bet token that pays the winnings of a successful wager at the qualifying minimum, with a 7-day expiry. Reading the offer as a £20 gift is the wrong read; reading it as a stake-back on a specific market is the right one.

The honest comparison of welcome offers is the comparison that puts the same offer on the same market at the same minimum odds, holds the wagering cap at 10x, and then works out what the offer is worth on average to a customer who clears it. That is a longer calculation than this paragraph can carry, but the conclusion that travels is short: the headline number on a welcome offer is the worst possible thing to compare, and the only thing worth comparing is what the offer actually pays in expected terms once the small print has been read.

Mobile and app: the on-device bookmaker

The UK sportsbook market is mobile-first. Most bets are placed from a phone, most live betting happens on a train or in a pub, and the apps have become the primary product rather than a desktop supplement. A bookmaker with a thin app is a bookmaker that has already lost the comparison for most customers.

The first thing to check is whether the app exists at all. A GB-licensed bookmaker that does not have a UK App Store or Google Play listing is not necessarily a poor operator, but it is a less mobile-friendly one, and the cost of the missing app shows up in friction — slower odds updates, no Face ID login, no native push notifications, no clean cash-out flow. Most of the featured set has both iOS and Android apps, and the comparison that matters is the comparison between the apps, not the comparison between an app and a website.

Face ID and biometric login is the new baseline. The customer who logs in with a fingerprint or a face scan is the customer who does not have a password to lose, and the licence condition on identity verification is met before the bet rather than at registration. bet365’s app supports Face ID on supported devices; the same pattern is true of 888sport and of most of the featured set.

In-play and live streaming. The two features that justify the app are in-play betting and live streaming. In-play lets the punter back or lay during the event; live streaming lets them watch the event on the same screen. A bookmaker with neither is a bookmaker that has decided it does not want the modern customer. bet365 offers both for a large set of events worldwide; Midnite shows in-play events with price boosts and acca-builder support; 888sport offers live streaming on racing. The depth of the in-play offering — the number of markets per event, the number of events covered, the delay between event and price — is the metric a comparison should be built on, and the metric the marketing does not give.

The bet builder. A bet builder is a same-game multi: a tool that lets the customer combine markets from one event into a single bet, with the odds adjusted to reflect the correlation between the legs. bet365’s Bet Builder+ is the most visible example and works both pre-match and in-play; other operators offer equivalents under different names. The depth of the builder is the question: how many markets per event, how many legs, what is the maximum combined odds, what is the minimum. A builder with three markets and a 100/1 ceiling is not a builder in the meaningful sense.

Push notifications and alerts. The mobile app’s strongest feature is the alert. The customer who gets a price-boost alert at half-time is the customer who backs the boost, and the operator who designs the alert well is the operator who keeps the in-play volume. The flip side is the marketing alert: a bookmaker that pushes promotional notifications at the customer who has asked for price alerts is a bookmaker that has made the alert less useful, and the trade-off between coverage and noise is the part of the design that does not show up in a feature list.

Predictions and strategy: what the comparison lets a customer do

A betting prediction is a forecast of an event. A betting strategy is a rule for staking and selection. The two are different things, and the comparison between bookmakers is a comparison on what the strategy can be — not a comparison on whose prediction is right, because nobody can know the outcome of a sporting event in advance and a tip that claims to know is a tip that has decided the punter is the one to lie to.

What a strategy looks like. The strategy is the rule, not the call. A flat-stake strategy bets the same amount on every selection, regardless of confidence; a proportional strategy bets a fixed share of the bankroll on every selection; a Kelly-style strategy bets a share of the bankroll scaled to the perceived edge. None of them knows the outcome in advance. What they do is keep the bankroll alive long enough for the edge, if there is one, to show. A bookmaker that supports a strategy is a bookmaker that does not cap the stakes, does not restrict the customer, does not close the account when the customer wins, and pays withdrawals promptly. A bookmaker that does those things is a bookmaker that has decided it does not want the long-term customer, and the comparison between operators is partly a comparison on whether they will let the customer keep betting.

Predictions. The published predictions industry — tipsters, betting-tip websites, social-media tipsters — is built on the claim that past form predicts future outcomes. Some of it is more rigorous than the rest. None of it is reliable in the sense a customer can act on without a model of their own. The right read on a tipping service is the right read on any other paid forecast: check the track record over hundreds of selections, check whether the record is independent (the service verifying its own winners is not independent), and treat the tip as one input into a model rather than the model itself. The bookmakers in the comparison do not run a tipping service — they sell odds. The customer’s job is to compare those odds and act.

A note on “compare predictions” searches. The phrase is short and the question behind it is short: who is going to win? The honest answer is that nobody can know, and a comparison that names a winner is a comparison that is wrong before it starts. What the comparison can do is show which bookmaker has the best odds on the favourite, the second favourite, the draw, the over 2.5, the BTTS yes, and the rest of the market — because the best odds on a known outcome are the part of the prediction a customer can actually use.

Bet types and odds: what the bet actually is

A bet is a contract: the customer stakes an amount, the bookmaker prices the outcomes, and the contract settles on the result. The stake is the customer’s money at risk. The return is the stake plus the winnings on a successful wager. The profit is the winnings alone. Decimal odds multiply the stake to give the return; fractional odds express the profit as a fraction of the stake. A 5/1 fractional price returns six times the stake (five times profit, plus the stake itself); the decimal equivalent is 6.00. A 1/2 fractional price returns 1.50 times the stake (profit half the stake, plus the stake itself); the decimal equivalent is 1.50.

The market margin. Every market a bookmaker offers has a margin built into the prices. The margin is the share of every unit staked that the bookmaker keeps on average across all outcomes. For a two-way market at 1.90 / 1.90 the calculation is straightforward: the reciprocal of each price is 0.5263, the sum is 1.0526, and the payout share is 1 ÷ 1.0526 = 0.9500, leaving a margin of 1 − 0.9500 = 0.0500, or 5.00%. A market priced at 1.85 / 1.85 is wider: each reciprocal is 0.5405, the sum is 1.0811, the payout share is 0.9250, and the margin is 7.50%. A market priced at 1.95 / 1.95 is tighter: each reciprocal is 0.5128, the sum is 1.0256, the payout share is 0.9750, and the margin is 2.50%. A margin of 2.50% is excellent for a mainstream sport; 5% is good; 7.5% is the kind of margin an unfancied event earns; double digits is the kind of margin a novelty market carries, and the customer who bets on a novelty market is the customer paying for the privilege.

The same arithmetic extends to three-way markets. For 1X2 football at 2.10 / 3.40 / 3.50, the reciprocals are 0.4762 / 0.2941 / 0.2857, the sum is 1.0560, the payout share is 0.9470, and the margin is 5.30%. The bookmaker keeps 5.3 pence of every pound staked on the match across all three outcomes, before considering the favourite-longshot bias that some markets carry. A margin of 5–6% on a Premier League match is competitive; a margin of 8–10% is uncompetitive, and the customer who prices two bookmakers against each other finds the difference in a single line.

The band the calculation gives. Worked through cleanly, the 1.90 / 1.90 example produces a margin of 5.00% on the nose, and a 1.95 / 1.95 example produces 2.50%. The page’s band on the cost of margin is the range that realistic pricing produces on a typical two-way event: roughly 2.5% to 7.5%, with the tighter end reserved for the deepest mainstream markets and the wider end for the more exotic ones. A specific bookmaker on a specific match on a specific day will sit somewhere in that band, and the customer who shops the line moves towards the tighter end.

Combination bets. A double is two selections; a treble is three; an accumulator (“acca”) is four or more. The combined price multiplies the leg prices, and the implied margin grows with the number of legs. A double at 1.90 / 1.90 carries a margin of 1 − 1 ÷ 1.0526 = 5.00% on each leg, but the combined margin is closer to 9.75% because the reciprocals multiply rather than add. A four-fold at 1.90 each leg carries a combined margin of 1 − 1 ÷ 1.0526⁴ ≈ 18.55%. The customer who builds a four-fold is paying the bookmaker nearly 19 pence of every pound staked on average, before any leg lets the bet down. The marketing of accumulator insurance refunds the stake on one losing leg; it does not lower the margin on the other legs.

Cash out. A cash-out offer lets the customer settle a bet before the event finishes, at a price the bookmaker sets. The cash-out price is built from the live prices of the remaining legs, with a margin layered on top. A cash-out at “fair value” would pay the live mid-price; a cash-out at the bookmaker’s price pays less, sometimes substantially less, and the difference is the bookmaker’s cut on the early settlement. The customer who cashes out a winning bet at a low margin is paying for the certainty; the customer who cashes out a winning bet at a high margin is paying the bookmaker for the privilege of locking in a profit that would have settled higher.

Each-way betting. An each-way bet is two bets of equal stake: one on the win, one on the place. The place terms vary by race and by operator — a fifth of the field pays a quarter of the win odds in a typical handicap, a quarter pays a quarter in non-handicap, an eighth pays an eighth. The each-way customer is paying for the place coverage and accepting that the place leg is structurally worse than the win leg. The place terms are part of the operator’s own rules, and the comparison between bookmakers is partly a comparison on place terms in similar races.

Betting exchanges. A betting exchange (Matchbook is the one in the featured set) runs on a different model. The exchange is the intermediary: it matches back bets and lay bets, takes a commission on the net winnings of the winning side, and does not set a margin in the same way a bookmaker does. The price on an exchange is set by the customers, the commission is the exchange’s cut, and the comparison between an exchange and a bookmaker is the comparison between a margin-based price and a commission-based price. For liquid markets on mainstream events the exchange is often tighter; for illiquid markets the exchange is often empty, and the bookmaker is the only game in town.

Sports and tournaments: what the comparison covers by event

The featured set is a sports-betting comparison, and the sports that dominate the volume are football, horse racing, tennis, and the major US sports. The depth of the offering on each sport is part of the comparison, and the depth varies.

Football. The Premier League is the volume driver. Every GB-licensed bookmaker offers the 1X2, the over/under, the BTTS, the Asian handicap, and the player markets. The depth is in the lower leagues and in the specials: who scores first, who gets booked, the match-result combined with the total goals. A bookmaker with a thin Championship offering is a bookmaker that has decided the customer who bets on the second tier is not its customer. Champions League and the European competitions sit alongside the domestic leagues; bet365’s status as the official global betting partner of the UEFA Champions League is a sponsorship, not a margin advantage, but it does mean the in-play offering on Champions League nights is the deepest in the market.

Horse racing. The meeting at the heart of British racing is the one the bookmakers price first. Best Odds Guaranteed (BOG) is the customer-facing offer: if the customer takes a price and the starting price (SP) is larger, the customer is paid at the larger price. BOG is the kind of clause that is hard to find on a comparison list and easy to find on a terms page, and it is the kind of clause that matters on a long-priced outsider. BetVictor offers BOG on UK and Irish racing; the same pattern is true of most of the featured set, and the comparison between them is the comparison on whether the offer extends to each-way bets and how the place terms are handled.

Tennis. The Grand Slams and the ATP/WTA tours are covered across the set. The depth is in the live markets: who wins the next set, who breaks next, the total games in the set. In-play tennis is one of the markets a serious comparison is built on, and the bookmaker with the thinnest tennis offering is the one that has decided tennis is a niche.

US sports. The NFL, NBA, MLB and NHL are covered across the featured set with varying depth. The customer who bets the NFL is the customer who wants the in-play offering and the player props; the comparison is on whether those markets exist at all and how deep they go.

Esports and virtuals. Esports are treated like any other event under the licence; the markets are the bookmaker’s own call. Virtual events are a separate licence category and a separate product. The customer who bets on esports is the customer who checks the operator’s terms before staking.

The Top 10: what each one does, and what it costs

The ten brands below are presented with a write-up and a verdict for each. The set is not a recommendation; the place in the ranking is the licence order, not a quality score. Each write-up closes on what the brand actually offers the punter and where it falls short.

1. 888sport — the broad-market bookmaker with a long feature list

888sport is one of the better-known GB-licensed brands and the trading name of 888 UK Limited, with Gambling Commission account 39028 and a remote general betting standard (real events) licence. The offering is broad: pre-match and in-play betting, Cash Out, a Bet Builder, racing live streams, BetFinder form tools, a live bet feed and a daily boosted-odds list. The combination is closer to a full-feature bookmaker than a niche.

The cost. The daily boosted-odds list is the kind of feature that pays back over a long period and is hard to value in a single bet. Cash Out is a margin-adding feature by construction; the early-settlement price is below the live mid-price, and the difference is the cost of the certainty. The Bet Builder is a same-game multi, and the combined margin on a three-leg builder at 1.90 legs is in the same cost band. None of this is unusual; it is the standard cost of the standard feature.

The verdict. 888sport is the right choice for a customer who wants one app to cover most of what they bet on, and the wrong choice for a customer who wants the absolute tightest margin on a Premier League match. The daily boosts are useful but not free; the live racing streams are useful and not unique. A punt at this bookmaker is a punt at a competent mid-market operator, and the comparison with the next brand on the list is a comparison on what the next brand does better.

2. Geoff Banks — the small-press bookmaker with ante-post depth

Geoff Banks is published by GB Sports Advisors Limited under Gambling Commission account 54095, with a remote general betting standard (real events) licence. The brand is smaller than 888sport, and the offering is built around the niche: live in-play prices and ante-post prices on future events. Ante-post is the market for backing an outcome weeks or months ahead of the event, and the depth of the ante-post book is the part of the comparison that matters for a customer betting on the Grand National in February or the Champion Hurdle in March.

The cost. Ante-post markets carry non-runner rules that differ from the day-of-race rules. A bet on a horse that does not run loses the stake; the bookmaker does not refund. The same bet placed on the day of the race, with the non-runner declared, falls under Rule 4 and a deduction. The comparison between ante-post and day-of-race is the comparison between a higher price and a non-runner risk, and the customer who places the bet at the higher price is paying for the price with the non-runner risk. The brand’s terms carry the rule; the customer’s job is to read it.

The verdict. Geoff Banks suits a customer who bets on futures and who values a deep ante-post book over the breadth of a 888sport. The narrower offer is a feature, not a flaw, and the comparison is on what the customer actually bets. Punters needing in-play tennis, a bet builder, and a daily boosted-odds list will find this brand less suited to their needs.

3. BoyleSports — the high-street name with an app-first sportsbook

BoyleSports is the trading name of Boylesports Enterprise under Gambling Commission account 39469, with a remote general betting standard (real events) licence. The brand is a high-street name in Ireland and the UK, and the app is built around the sportsbook. The current welcome offer for UK players is £20 in free bets for a £10 qualifying bet (€30 in free bets for a €10 bet for Irish players).

The cost. The £20 is not £20 of value; it is a free-bet token that pays the winnings of a successful wager, with the stake not returned. The expected value of a free bet depends on the market it is used on, and the market the offer steers the customer towards is the market the brand wants the customer to bet on. The 7-day expiry is the standard. A customer who lets the free bet expire has paid the qualifying bet and received nothing in return; a customer who uses the free bet at minimum odds on a low-margin market has paid the qualifying bet and received the winnings net of the free-bet cost. The arithmetic is the same, with the customer’s market chosen by the offer terms.

The verdict. BoyleSports suits a customer who has a specific market in mind for the free bet, who bets on football, racing and the mainstream sports, and who is comfortable with the standard 7-day expiry. The welcome offer is mid-table; the brand underneath is mid-table, and the comparison with the next brand is the comparison on what the next brand does better. Those looking for the deepest ante-post book or broadest US sports offering may find more suitable alternatives.

4. Hollywoodbets — the stake-back offer on the first acca

Hollywoodbets is the trading name of Hollywoodbets International UK Limited under Gambling Commission account 53028, with a valid GB licence for sports betting. The sports welcome offer is a stake-back on the first qualifying losing accumulator: a £10+ deposit by card, a first acca of £10+ with three or more legs at minimum odds of 4/1, settled within seven days, returning a free bet of up to £30 on a losing bet, one free bet per customer.

The cost. The 4/1 floor on each leg is the meaningful number. At 4/1, three legs all landing is a roughly 1-in-125 outcome (1.9% implied per leg, allowing for margin, with three legs roughly compounding). The offer is structured so the customer either wins the first acca and gets no free bet, or loses the first acca and gets a free bet whose stake is not returned. The 4/1 minimum is not a soft floor; it is the floor the offer is built around, and the customer who bets shorter than 4/1 does not qualify. The 7-day settlement window and the one-per-customer limit are the standard small print.

The verdict. Hollywoodbets suits a customer who was going to place a first acca anyway and who accepts the 4/1 minimum. The free bet is a hedge on the first-bet outcome, not a gift, and the offer’s value depends on whether the customer would have placed the bet regardless. Customers wanting single-bet offers or betting shorter than 4/1 may find better value elsewhere.

5. Dabble — the £10-for-£10 free bet offer

Dabble is the trading name of Dabble Sports UK Ltd under Gambling Commission account 65677, with a valid GB licence for sports betting. The welcome offer is a £10 free bet on a £10 first deposit for new customers, with a minimum-odds requirement, a 7-day free-bet expiry, and the stake not returned on a winning free bet.

The cost. The £10 is a free-bet token, not £10 of withdrawable cash, and the value is the winnings of a successful wager at the qualifying minimum odds. The 7-day expiry is the standard. The minimum-odds requirement is the part that decides whether the customer is realistically going to use the token: a 1/2 (1.50) minimum is easy to clear, a 4/1 (5.00) minimum is harder, and the difference shows up in expected value.

The verdict. Dabble suits a customer who wants a simple offer and who has a market in mind at the qualifying minimum. The £10-for-£10 framing is the kind of headline that reads better than the arithmetic, and the customer who treats it as £10 of value is the customer who will be surprised on settlement. Others looking for stake-back offers or futures markets should look elsewhere.

6. Matchbook — the betting exchange with a separate pricing model

Matchbook is the trading name of Triplebet Limited under Gambling Commission account 39504, with a remote general betting standard (real events) and remote betting intermediary licence. The latter is the exchange category, and the comparison between Matchbook and a fixed-odds bookmaker is the comparison between a commission-based price and a margin-based price. Triplebet also operates the Betdaq brand, which has been acquired and is run alongside Matchbook; Betdaq accounts do not transfer to Matchbook and the two brands are separate.

The cost. An exchange charges commission on net winnings, not margin in the price. The commission is the operator’s cut; the price is set by the customers. For a liquid market on a Premier League match the price on Matchbook is often tighter than the price on a fixed-odds bookmaker, and the customer who backs at the exchange price pays the commission on the net winnings rather than the margin in the odds. For an illiquid market the exchange may have no quotes at all, and the fixed-odds bookmaker is the only option.

The verdict. Matchbook suits a customer who is comfortable laying bets, who wants the tightest price on a liquid market, and who is willing to learn the mechanics of an exchange. The pricing model is different; the comparison is a comparison on which model the customer prefers. Those seeking cash-out, bet builders, or daily boosts typical of fixed-odds bookmakers should consider other options.

7. Spreadex — the spread betting and fixed-odds hybrid

Spreadex is the trading name of Spreadex Limited under Gambling Commission account 8835, with a remote general betting standard (real events) licence. Spreadex is also regulated by the Financial Conduct Authority for spread betting. The combination is unusual: a bookmaker that offers fixed-odds sports betting on the same platform as financial spread betting, with the FCA and the Gambling Commission covering their respective halves.

The cost. Spread betting carries a risk the fixed-odds side does not: the loss can exceed the deposit. The spread bettor who gets the direction wrong can lose more than they staked, and the FCA requires the firm to flag the risk. The fixed-odds side carries the same cost as any other bookmaker: the margin in the price, the terms on the welcome offer, the cap on free-bet winnings, the same as the rest of the set.

The verdict. Spreadex suits a customer who specifically wants spread betting and fixed-odds on the same platform. The dual regulation is a feature for the customer who understands the products; the loss-can-exceed-deposit risk on the spread side is a cost the marketing does not always lead with. Those wanting a deep fixed-odds book without the spread-betting component may find more straightforward alternatives.

8. BetVictor — the racing bookmaker with Best Odds Guaranteed

BetVictor is the trading name of BV Gaming Limited under Gambling Commission account 39576, with a valid GB licence for sports betting. The brand has a long history in the British market and the offering is built around horse racing: Best Odds Guaranteed on UK and Irish racing, enhanced live race streaming, a BetFinder feature for finding racing bets, and Smart Stats for form study.

The cost. BOG is the headline offer. The customer who takes a price and the SP is larger is paid at the SP, and the offer is most useful on a long-priced outsider where the SP drift is largest. The cost is built into the everyday price: the bookmaker offering BOG is the bookmaker whose morning price is, on average, slightly shorter than the bookmaker that does not offer BOG, and the comparison on a single race is the comparison on which bookmaker’s price is larger on the day.

The verdict. BetVictor suits a customer who bets on UK and Irish racing and values BOG, the racing live streams, and the form tools. The racing focus is a feature for the racing customer and a narrowing for the customer who bets across sports. Those betting primarily on football in-play or wanting broader US sports coverage might look elsewhere.

9. Octobet — the half-back welcome offer with a casino add-on

Octobet is the trading name of Octopus Game Limited under Gambling Commission account 62545; it holds a remote licence to operate sports betting in Great Britain. The sportsbook welcome offer is 50% back as a free bet up to £50, plus a £10 casino bonus for new customers. The dual-product structure is the point: the offer is built to get the customer to try both halves of the site.

The cost. The 50% back is a stake-back, with the stake not returned on a winning free bet. The 50% ceiling means a £10 losing bet returns a £5 free bet; a £100 losing bet returns a £50 free bet. The casino bonus carries its own wagering requirement, capped at 10x under the 19 January 2026 rule, and the cross-product nature of the offer sits on the side of a mixed-product promotion that the LCCP allows only where the betting and casino legs are separable. The customer who clears the sportsbook half separately from the casino half is the customer who is operating within the rule; the customer who treats the offer as a single gift is the customer who will be surprised on settlement.

The verdict. Octobet suits a customer who was going to bet on the sportsbook and play the casino anyway. The 50% structure rewards the larger first bet more than the smaller one, and the cap at £50 is a ceiling on the headline. Those interested in a single-product offer or betting smaller than £20 on the first bet may prefer another brand.

10. Bet Ahoy — the split free bet on sports and acca

Bet Ahoy is the trading name of Bet Ahoy Ltd under Gambling Commission account 100094; it is licensed to provide sports betting services within Great Britain. The welcome offer is “Bet £10 & Get £10 in Free Bets”, made up of a £5 sports free bet and a £5 acca free bet. The split is the point: the offer is built to get the customer to use one half on a single, the other half on a multi.

The cost. The £5 sports free bet pays winnings only; the £5 acca free bet pays winnings only. The split means the customer is steered towards both halves of the offering, and the expected value of each half depends on the market. The 7-day expiry is the standard. The split is a real restriction: a customer who would rather use £10 on a single is forced to use £5 on the single and £5 on the acca, and the restriction is a real cost.

The verdict. Bet Ahoy suits a customer who bets on both singles and accumulators and is comfortable with the split. The £10 headline is a smaller headline than the £20 BoyleSports offers, but the structure is similar. It is the wrong choice for a customer who bets on singles only or who wants the deepest ante-post offering.

The fundamentals: how to compare two bookmakers

The comparison above is built on what the brands publish. The comparison a customer does themselves runs through the same fields, in the same order, and ends on a verdict the marketing does not give.

The table is a starting point, not a verdict. The fields that decide between two bookmakers on a given bet are the margin on the market, the depth of the in-play offering, the cash-out margin, the cap on free-bet winnings, and the time it takes to withdraw. Each of these varies by market, by event, and by the customer’s account history, and a single comparison cannot pin them all. The job of the comparison is to give the customer the questions; the customer does the rest on the terms pages of the brands they actually bet with.

Off-brand: what the GB licence does not give the customer

A GB-licensed bookmaker gives the customer the protection the LCCP requires and the duty of care the Commission enforces. It does not give the customer a margin guarantee, a payout guarantee, a deep in-play offering, or a free-bet value that the small print does not eat. The licensed bookmaker is the floor, and the comparison above the floor is the comparison the rest of this page does.

The offshore alternative. A bookmaker licensed only in Curaçao, Malta or Gibraltar is reachable from a British address, and the Commission’s 2014 change means the operator is in breach of section 33 of the Gambling Act 2005 the moment it accepts a British customer. The enforcement is against the operator; the customer is not prosecuted. What the customer gives up is the protection: no GAMSTOP coverage (the offshore brand is not in the scheme), no Commission complaints route, no approved dispute-resolution body, no British consumer redress if funds are withheld, no 10x bonus cap, no £150 vulnerability check. The brand may pay out promptly and offer a tight margin; it may not. The customer’s only protection is the brand’s own terms and the brand’s own regulator in its own jurisdiction, and the brand’s own regulator does not owe the British customer a duty of care.

The honest read. The GB-licensed brand is the brand the Commission can hold to account if something goes wrong. The offshore brand is the brand the customer takes on trust. The customer’s read on the trade-off is the customer’s call, and a comparison that pretends the trade-off does not exist is a comparison that has decided to lie.

Frequently asked questions

Where to compare online betting odds?

The price-comparison sites (sometimes called odds-comparison sites or odds trackers) carry prices on a given event across multiple bookmakers and show the best price on each outcome. The comparison is the right place to start; the customer who wants the tightest margin on a Premier League match reads the prices on the comparison site, opens an account with the bookmaker offering the best price, and stakes there. The comparison site is not a bookmaker and does not place the bet itself; the bet is placed at the bookmaker whose price was the best.

How to compare betting odds?

Three steps. First, pick the market — the 1X2, the over/under, the BTTS, the player prop — and the event. Second, get the price from at least three GB-licensed bookmakers on the same selection. Third, read the small print on each: the maximum stake, the rule on cash-out, the rule on a void outcome, the rule on a Rule 4 deduction. Two bookmakers at the same decimal price may have different rules, and the rule difference is the part of the comparison that decides which one to back. The same arithmetic extends to combination bets, where the combined price is the product of the leg prices and the combined margin is built from the reciprocals.

How to compare betting site features?

The comparison runs on the same five questions across every brand. First, what is the welcome offer and what is the wagering requirement, the minimum odds, the expiry, and the cap on winnings? Second, what is the in-play offering, how many markets per event, how many events, and what is the delay? Third, what is the live-streaming offering, on which sports, and at what account level? Fourth, what is the cash-out offering, on which markets, and at what margin? Fifth, what is the bet builder, how many markets per event, and what is the maximum combined odds? The five questions applied across the set produce a comparison the marketing does not.

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

The Commission’s public register is the only check. It can be searched by business name, trading name, domain, or account number. The account number is the unique identifier on the register; the licence number follows a different format. The register carries the licence type, the licence holder, the trading names, the domain names, and the status (active, suspended, revoked). A brand that does not appear on the register is not GB-licensed, and the brand’s own claim of a licence is not a substitute. The check takes a minute and is worth doing before the first deposit, not after the first problem.

How is the return on a bet worked out from the stake and the odds?

Return equals stake times decimal odds. Profit equals stake times (decimal odds minus 1). A £10 stake at 3.50 returns £35 and pays £25 profit. A £10 stake at 1.50 returns £15 and pays £5 profit. The fractional price is the profit as a fraction of the stake: 5/2 fractional (decimal 3.50) pays £25 profit on a £10 stake; 1/2 fractional (decimal 1.50) pays £5 profit on a £10 stake. The return is the stake plus the profit, and the calculation works for single bets and for combination bets where the leg prices multiply into one price.

What is the bookmaker’s margin and how can it be seen in the odds?

The margin is the share of every unit staked the bookmaker keeps on average across all outcomes. The arithmetic is: reciprocal of each price, summed, the sum inverted to give the payout share, and 1 minus the payout share to give the margin. For a two-way market at 1.90 / 1.90, the reciprocals are 0.5263 each, the sum is 1.0526, the payout share is 0.9500, and the margin is 5.00%. For a three-way 1X2 at 2.10 / 3.40 / 3.50, the reciprocals are 0.4762 / 0.2941 / 0.2857, the sum is 1.0560, the payout share is 0.9470, and the margin is 5.30%. Tighter margins mean more of the stake is returned to customers on average; wider margins mean less. The margin is the bookmaker’s cut, hidden in the price, and the customer who reads the margin is the customer who knows the cost of the bet before the bet is placed.
