In Great Britain the comparison is shorter than the marketing suggests. A bookmaker that takes a customer in England, Scotland or Wales needs a Gambling Commission licence wherever it sits on the map, and the Commission’s public register is the whole test of who holds one. That makes the licensed set the legitimate set, and it makes the rest of the comparison a matter of taste, terms and what each house asks of the punter who signs up.

What follows is a working comparison of ten licensed remote bookmakers: licence and operator on every card, the welcome offer each site publishes on its own terms, the mobile app, the safer-gambling toolkit and the small print that decides whether the headline number is the one a bettor actually keeps. Two ideas run through it. The first is that a bonus headline is the smallest part of a bonus: the turnover, the minimum odds and the deadline decide what it costs. The second is that a price the bookmaker writes is a price the bookmaker has already kept a margin inside; the arithmetic at the end of the piece shows what that margin looks like.

Data is current as of 27 October 2026 against the Gambling Commission’s public register and each operator’s own published terms.

How this comparison is built, and what each shelf of it does

A comparison of betting sites is not a list of logos. The ten names below come off the Commission’s register as holders of an active remote general betting licence; beyond that, they look nothing like each other. One is a sports-only platform with live streaming and an in-house bet builder, another runs as a betting exchange where punters lay each other rather than the house, a third still offers spread betting on financial markets under a separate regulator. Picking among them is a question of what a punter bets on, what they spend, and how much of the small print they have the patience to read.

The shelves that follow each do one job.

• The ranking sorts the ten licensed operators by what they bring to a comparison in 2026 — depth of market, the tools around the bet, the welcome offer’s actual cost — and tells the reader who each one suits.
• The overview lays out the fundamentals: what a betting site is in the British sense, what licence category covers it, and what the player faces in the first five minutes (age 18, name and address verified before a deposit, no anonymous play).
• Legality is its own shelf because the British answer is statutory and worth stating in plain terms: the Gambling Act 2005, the 2014 point-of-consumption change, and what a non-GB licence means in practice.
• Responsible gambling sits next, because every licensed brand is in GAMSTOP and the LCCP rules on deposit limits and vulnerability checks apply to all of them — these are not features to shop for, they are the floor.
• Bonuses and free bets take the marketing headlines and turn them into the figures that decide the cost.
• Mobile and apps covers what changes when the bettor stops using a laptop and starts using a handset.
• Predictions and strategy handles the searcher who has come to compare odds today and wants to know what an odds comparison is worth.
• Bet types and odds is the working vocabulary — single, accumulator, each-way, cash out, the betting exchange’s back-and-lay — and the calculation that shows what the bookmaker’s margin looks like inside a price.
• Sports and tournaments closes the working shelves with how each operator fits the British fixture list.

The last sections cover each of the ten operators in turn; the FAQ at the end answers the questions that come up most often once a punter has narrowed the shortlist.

The ranking: ten licensed bookmakers, in the order the comparison puts them

A ranking of licensed bookmakers cannot rest on licence alone. The licence is the floor; the order on this page is built on the comparison’s other questions — what each operator bets on, how the app handles the bettor’s everyday wager, what the welcome offer costs after the small print, and where the brand still earns the licence fee’s value. The order below is one the British shortlist tends to arrive at when a punter weighs those questions; readers looking for a different answer will find a different order inside each shelf that follows.

1. bet365 — depth of market and live streaming across most British sports, plus Bet Builder+ for same-game multiples.
2. 888sport — a broad sportsbook with Cash Out, Bet Builder and a steady stream of boosted odds on Premier League and racing.
3. BetVictor — best odds guaranteed on UK and Irish racing, racing streams and a BetFinder form tool.
4. BoyleSports — strong across horse racing and football, with a £20-in-free-bets welcome for £10 staked.
5. Spreadex — the only bookmaker in this ranking that also offers financial spread betting under a separate FCA regulator.
6. Hollywoodbets — South African heritage, a focus on racing and football, and a stake-back free bet for a losing acca.
7. Matchbook — a betting exchange where punters back and lay against each other, with a commission model instead of a margin.
8. Dabble — a social-leaning app whose welcome offer is £10 in free bets for a £10 first deposit.
9. Octobet — a sportsbook whose welcome offer is half the qualifying stake back as a free bet, with a casino side.
10. Bet Ahoy — a smaller sportsbook offering £5 in sports free bets and £5 in acca free bets for a £10 opening bet.

Three more licensed names appear below the ranking in their own slots: Geoff Banks (live in-play and ante-post on racing and football), Kalooki Sportsbook (a sports-only platform with a small licence footprint), Midnite (an esports-rooted sportsbook with a popular acca builder), Unibet (a long-running Scandinavian-licensed brand on Platinum Gaming’s UK account), BetMGM UK (LeoVegas-published), 10bet, Betmaster, BetWright, London.bet, Copybet, Fitzwilliam Sports, Silkbet, Lottoland UK and Kwiff — each described where the comparison turns to the part of the market they serve.

A note on what the ranking is not. It is not a “best betting site” list in the consumer-magazine sense; the licence test is binary, the marketing claims are not, and what suits a £2-each-way punter on the National Hunt does not suit a football-trader with a Bet Builder habit. Each write-up below says who the brand suits and where it does not.

What a UK betting site actually is, and what the licence covers

A betting site in the British sense is one of two things. Either it is a bookmaker that takes fixed-odds bets on sporting events and pays out at the price it has written — the model the ten ranked names mostly run — or it is a betting exchange that lets two customers back and lay against each other and takes a commission on net winnings. The licence category differs: a remote general betting standard (real events) licence covers the first; a remote betting intermediary licence covers the second, and Matchbook in this ranking is the only name that runs on one.

What every site on this page has in common sits upstream of those distinctions. Each is licensed by the Gambling Commission under the Gambling Act 2005 (since the 2014 amendment, an operator whose remote facilities are used in Great Britain needs a Commission licence wherever it is based). Each is on GAMSTOP. None of them takes anonymous play: since 7 May 2019, name, address and date of birth are verified before the customer can deposit or gamble, including on a free bet or bonus. The minimum age is 18, and the marketing rules around the 25-year-old image cap concern who appears in an advertisement, not who may bet.

The categories on the Commission’s register matter more than they look. A remote general betting licence covers real sporting events; virtual events are a separate category. Pool betting on horse and dog racing has its own licence. Spread betting on financial markets is regulated by the FCA, not the Commission. An operator on the register under one category may not be licensed under another; the register, searchable by business name, trading name, domain or account number, is the only test.

The British legal frame, and what a non-GB licence is worth here

The honest lead for a British bettor is short. The Gambling Act 2005 covers Great Britain — England, Scotland and Wales — and is enforced by the Gambling Commission, a non-departmental public body sponsored by the Department for Culture, Media and Sport. Northern Ireland has its own older law; a GB licence does not regulate a Northern Ireland customer and a Northern Ireland licence does not cover a GB one.

Since the Gambling (Licensing and Advertising) Act 2014 the rule has been point-of-consumption: an operator needs a Commission licence wherever it is based if it takes remote bets from a customer in Great Britain. Sections 33 and 36 of the 2005 Act, as amended, are the relevant offences. A Curaçao, Malta or Gibraltar licence is no substitute for a British one; the brand may be reputable, the regulation is not British.

There is no state monopoly and no cap on the number of licences. The register lists far more brands than any article could feature. No single brand is “the only” licensed one; a place on this page is not a licence, and an exclusivity claim of that shape would be wrong on its face.

What the licence buys the bettor is the package named in the LCCP — the Licence Conditions and Codes of Practice — and the social responsibility code that sits inside it. KYC verification before the first deposit; GAMSTOP coverage; the 10x wagering cap on bonuses (since 19 January 2026, no bonus carries more than ten times its value in turnover); a financial vulnerability check at £150 of net deposits in a rolling 30 days (since 28 February 2025); safer-gambling tools as a condition, not a feature; a Commission complaints route; an approved alternative dispute-resolution body. The bettor also pays no tax on winnings — General Betting Duty is the operator’s tax on gross profits, currently 15% and rising to 25% on remote betting (other than remote bets on UK racing) from 1 April 2027 — and never write that the player is charged duty.

What it does not buy is anonymity, an unlimited bonus, a maximum size of stake set by statute, or a guarantee that any particular market will be offered. Operators set their own maximum stakes and may restrict a customer on the operator’s own terms. In-play betting is offered under each operator’s licence conditions; it is not “unrestricted” as a legal conclusion, and the controls are operational, not statutory.

What a non-GB licence costs the bettor is the absence of that package. No GAMSTOP coverage; no Commission complaints route; no approved dispute-resolution body; no British consumer redress if funds are withheld; not bound by the 10x bonus cap or the £150 vulnerability check. It is also not an offence aimed at the customer to bet on an unlicensed site; what the bettor loses is the protection, not the liberty. Neither the licensed nor the unlicensed choice is “the safe choice” by default; the licensed choice is the one with a regulator attached, and that is the comparison this page runs.

Responsible gambling: the floor every licensed site sits on

Every name on this page runs on a Gambling Commission licence, and that licence carries the same floor of player-protection rules regardless of marketing. The LCCP and the social responsibility code write them in, and the Commission’s enforcement arm applies them. Two of those rules are worth understanding in detail because they shape what a punter experiences day to day.

The first is GAMSTOP, the national multi-operator online self-exclusion scheme. Self-exclusion at one licensed brand excludes the customer at every online GB operator; the scheme became a mandatory licence condition for online operators on 31 March 2020. The minimum period is six months; periods run to 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 remove it. GAMSTOP covers online sites and apps; betting shops use a separate service. Every brand on this page is a GAMSTOP member.

The second is the financial vulnerability check under LCCP condition 3.4.4, in force since 30 August 2024 and extended in scope since 28 February 2025. Once a customer’s deposits minus withdrawals exceed £150 in a rolling 30 days, the operator runs a public-record check — bankruptcy, county court judgments, similar — at the licensed site. It is not an income check and not a credit reference check; the data sources are public records. The bettor sees a check, not a refusal; the check is part of the operator’s social responsibility duty.

Deposit limits sit alongside, under the Remote Technical Standards. Operators must offer a gross deposit limit on a fixed time frame; the first phase has applied since 31 October 2025 and a second phase was postponed to 30 September 2026. Whether that second phase is live in 2026 is not established here; describe it as “announced, in phases”, not “in force”.

The financial risk assessments the press calls affordability checks are a separate, larger plan, announced in a Commission article of 7 July 2026 with no start date; the comparison does not write them as live.

Help, when a customer wants it, is independent of the operator. GamCare runs the National Gambling Helpline; GambleAware funds treatment and education; the NHS runs gambling clinics; Gamblers Anonymous runs peer support. Several of the brands on this page surface those links in their safer-gambling pages, and the link goes through to the right place regardless of the brand.

Two further rules shape the day-to-day. Credit cards are banned for gambling in Great Britain, since 14 April 2020, including credit-card-funded payments through an e-wallet; debit cards and bank-based payments are not covered. No state-set deposit or loss ceiling for betting exists — limits are the customer’s choice. Spread betting on financial markets, where Spreadex in this ranking operates, is regulated by the FCA; the Commission does not cover that side of the business, and a customer laying a financial spread has different redress.

Bonuses and free bets: what the headline buys, and what the small print takes back

The welcome offer is the part of the comparison a reader skims to first and the part they regret skim-reading last. Marketing writes the headline; the small print decides the cost. The shelf that follows takes each offer the comparison has named, names the headline on the operator’s own terms, then reads the conditions the way the operator has published them. No bonus, no offer and no promo code appears on this page in working form: the comparison describes what an offer is worth, not how to claim it.

A few terms run across every offer on this page and are worth stating once, in the words the operators use.

• Free bet is a token the customer wagers once; on a win, the stake is not returned, and what the customer has is the winnings, not the stake-plus-winnings. That is why a £10 free bet at evens (£2.00) pays £10, not £20.
• Best odds guaranteed (BOG) means the operator pays the starting price if it is higher than the price the customer took; BetVictor in this ranking names it on UK and Irish racing.
• Enhanced odds and price boosts are higher prices on selected selections for a short window; the stake and the payout follow the operator’s stake rules.
• Accumulator insurance refunds a stake as a free bet if one leg of an acca lets the punter down, usually when there are five or more legs and the operator’s minimum-odds rule is met.
• Cashback returns a share of net losses over a period; the form is the operator’s choice.
• Wagering requirement is the multiplier of bonus value the customer must turn over before the bonus is withdrawable; since 19 January 2026 the cap is 10x, and the Commission applies it.
• Stake not returned is the line that turns a “free bet” into a free-bet token rather than a refund; the offer is described on its own terms, with that distinction kept.
• Minimum odds decide which selections count toward wagering; an acca at 4/1 or greater is a common floor.

A wagering requirement at the 10x cap is the headline’s first filter. A £10 bonus at the cap needs £100 of qualifying bets; at 50x it would need £500. The cap has been in force since 19 January 2026 and applies to every licensed brand on this page. Mixed-product promotions — “bet on football to get free spins” — have been banned in the same rule change.

A welcome offer is also deposit-gated, odds-gated, expiry-gated and stake-gated in ways the headline does not show. The shelf below does not promise a free-bet value; it says what the headline means and what the small print costs.

Mobile and apps: what the bettor does on a handset

A British punter in 2026 bets on a phone more often than on a laptop, and the app is the surface the operator most often sells. The comparison shelves below look at what changes between a desktop site and an app, and at what each operator’s app does that the desktop does not. A note on what is not on this shelf: the app ratings, the download numbers and the in-app UX details that change every release. Those age fast, and the comparison reads from what each operator’s store listing and site say, not from a benchmark.

Three things distinguish a strong British sportsbook app in 2026.

• Face ID and biometric login. bet365’s listing names Face ID on supported devices; that is the level the better apps reach.
• Live in-play and live streaming. Streaming on a phone, on the bettor’s data plan, is what separates the apps that handle in-play from the apps that point at it. In-play betting is offered under each operator’s licence conditions, and the controls are operational.
• Bet Builder on the slip. Bet Builder and Bet Builder+ combine markets from one event into a single bet; bet365 names Bet Builder+ pre-match and in-play. 888sport names a Bet Builder; Matchbook, as an exchange, settles on its own slip.

A live streaming shelf sits inside the app where the operator has rights. BetVictor names enhanced live race streaming alongside BOG; bet365 names in-play streaming of events worldwide; 888sport names racing streams. None of these is a free-standing feature — they live inside the operator’s rights portfolio, and a stream that exists on Monday may not exist on Saturday, depending on the deal.

Payments from a phone lean on Apple Pay and Google Pay, plus debit card and PayPal. Midnite names Visa, Mastercard, Apple Pay, Google Pay and Trustly; bet365 names debit card, PayPal and Apple Pay; the rest follow the same pattern. The credit-card ban covers the mobile side as much as the desktop side; an e-wallet funded from a credit card does not work either.

App age ratings are 17+ for the gambling apps in this ranking. That is the App Store’s gate, not the operator’s licence; the legal age to bet is 18.

Predictions and strategy: what an odds comparison is worth

The searcher who has come to compare odds today usually has one of three things on their mind. They want to know which site is paying the best price on a particular selection; they want to know how to compare two prices without losing the calculation in the format change; or they want a tip, a forecast, a system that wins. The shelf below answers the first two and refuses the third, because nobody can know an outcome and a reader who acts on a predicted one loses real money on this page’s word.

An odds comparison is a price comparison. The British bookmaker publishes decimal odds (6.00, 3.75) and, where the operator’s site is older or covers racing, fractional odds (5/1, 11/4, evens); the conversion is a/b → a ÷ b + 1, so 5/1 in decimal is 6.00, 11/4 is 3.75, evens is 2.00. A price of 2.50 means a £10 stake returns £25 (£10 stake plus £15 profit); a price of 6.00 means a £10 stake returns £60 (£10 stake plus £50 profit). Two prices on the same selection are comparable only when both are converted to the same format.

An odds comparison on the same event across licensed operators usually shows small differences. A £10 stake at 2.50 returns £25; at 2.55 it returns £25.50. Over a season of small-stake bets that adds up, and an odds-comparison site exists to surface it. What the comparison cannot surface is the operator’s other rules: stake limits on boosted odds, restricted accounts, market availability, terms on free bets attached to a selection.

A prediction is not part of the comparison. A tip, a system, a model — all of these claim to know something about an outcome that the operator’s own traders have priced; the consistent finding is that they do not, and the licensed bookmaker’s margin is the only number the price carries with certainty. A bettor who wants a tip is paying for a tipster’s marketing, not for an edge.

A strategy the comparison does endorse is bankroll discipline: stake as a share of the bank, stop at the stop, walk away on the bad week. The Commission has no view on staking strategy; the bankroll’s discipline is the bettor’s.

Bet types and odds: the working vocabulary, and what the margin is

A British punter meets a small working vocabulary every time a slip opens. Single, double, treble, accumulator (“acca”); each-way on racing; bet builder on football; cash out on in-play; spread betting at the one operator that offers it; back and lay at the betting exchange. The shelf below sets out what each is and what it costs the punter, and closes with the calculation that shows where the bookmaker’s margin sits inside a price.

Single. One selection, one stake, one return. A £10 single at 2.50 returns £25.

Double, treble, accumulator. Two, three or more selections combined into one bet; the odds multiply into one price. A double of 2.50 and 3.00 has combined odds of 7.50; a £5 double returns £37.50. An accumulator with more legs carries a higher combined price and a smaller hit rate.

Each-way. Two bets of equal stake — one on the win, one on the place — at the same odds; the stake doubles, and the place terms vary by race and operator. An each-way single at 2.50 with a £5 stake is £10 staked across two bets.

Bet Builder / same-game multi. Combines markets from one event into a single bet; bet365 names Bet Builder+ as available pre-match and in-play.

Cash Out. Settles a bet before the event ends, at a price the operator writes; the operator’s margin sits inside that price and the bettor is paying for certainty.

Betting exchange. Matchbook in this ranking is the exchange; punters back and lay against each other and the operator takes a commission on net winnings, rather than running a margin.

Spread betting. Spreadex in this ranking is the one operator that runs financial spread betting on top of its sportsbook; losses can exceed the deposit, and the regulator is the FCA, not the Commission.

Wagering requirement. The multiplier of bonus value the customer must turn over before the bonus is withdrawable; capped at 10x since 19 January 2026.

Margin. What the bookmaker keeps out of every unit bet on a market; the calculation is below. A 5% margin means 95 pence in payout share for every pound staked across all outcomes.

The margin, worked out

The bookmaker’s margin is the share of every pound staked on that market that the operator keeps, averaged across all outcomes. The payout share is the share returned to the punter, and the two add up to 100%. The arithmetic is mechanical and worth doing once.

Take an illustrative two-way market at decimal odds 1.90 / 1.90. The implied probabilities are 1 ÷ 1.90 on each side, which gives roughly 52.63% per outcome. The payout share is the inverse of the sum of those probabilities: 1 ÷ (0.5263 + 0.5263) = 1 ÷ 1.0526, which is about 95.00%. The margin is 1 − 0.9500, or about 5.00%.

That is the floor of the answer. A real margin depends on the operator, the market and the event; for a popular Premier League match the margin on the 1X2 market is typically tighter than 5%, for a smaller football league it is wider. The result above is a band — a starting point at even prices, not a quoted price from a single operator on a given day. The page presents it as a band with its condition: at 1.90 / 1.90 the margin is around 5%; at 1.80 / 1.80 the margin tightens to roughly 5.6%; at 2.00 / 2.00 the margin widens to roughly 5.3%. The market’s margin is what the punter pays for the convenience of a one-slip bet, and a narrower margin is a better price at the same selection.

Sports and tournaments: how each operator fits the British fixture list

A British sportsbook lives or dies on its football and racing. Premier League, Champions League, the domestic and European cups, the Championship and the lower leagues; the National Hunt, the Flat, the big meetings at Cheltenham, Aintree, Ascot and Goodwood; the international cricket, the Six Nations, the Open, Wimbledon, the Grand Slams. The shelf below is what each of the ten ranked operators does with those fixtures, and where the long tail — darts, snooker, MMA, the niche esports — fits.

Football is the core. Every ranked operator runs an extensive Premier League book with pre-match and in-play markets; 888sport, BetVictor, BoyleSports and Hollywoodbets are strongest on the football-and-racing pair the British punter tends to split their betting time across. Bet Builder and Bet Builder+ combine match markets into a single slip; 888sport, bet365, BoyleSports and Hollywoodbets name the feature on their listings.

Horse racing is the second pillar. BetVictor names best odds guaranteed on UK and Irish racing, ante-post markets, racing streams and a BetFinder form tool; 888sport names racing streams and a daily boosted odds feed; BoyleSports and Hollywoodbets name racing markets as part of their core offer. The Commission’s pool betting licence is a separate category on the register; most of the ranked operators are not licensed for pool betting and run fixed-odds books instead.

In-play is everywhere. bet365, 888sport, BetVictor, BoyleSports, Hollywoodbets, Dabble, Octobet, Bet Ahoy, Spreadex and Matchbook all offer in-play markets; the depth varies by event. In-play controls are the operator’s licence conditions and customer-protection duties, not a statutory list.

Niche sports and esports are where the operators with a specific focus pull away. bet365 names live streaming of events worldwide, plus Bet Track, Match Live and a Live Golf Tracker for following bets in play. Midnite, with an esports-rooted origin, runs esports markets alongside the more conventional football and racing. Matchbook, as an exchange, settles on the punter’s side of the bet on the markets the liquidity supports.

Tournaments cut across sports. The Champions League — bet365 is the official global betting partner — and the Premier League, the Grand Slams, the Six Nations, the Open, the domestic cups. The bookmaker’s margin is tightest on the events with the deepest liquidity, widest on the niche; a small-stake bettor pays more per unit on the long tail than on the head.

The table: ten licensed bookmakers at a glance

The comparison table below carries the four matters a British shortlist tends to settle first: the brand, the Gambling Commission account number and licence holder, and what the operator’s own terms say on the offer. The headline number on the offer is described, not printed in working form.

Three further licensed names appear in this ranking and are written up below the table: bet365 (Commission account held by Hillside (New Media) Limited), Unibet (45322, Platinum Gaming Limited), Midnite (101839), BetMGM UK (39198, LeoVegas Gaming), 10bet (43173), Betmaster (65699, BM Solutions GB Ltd), BetWright, London.bet (Thistle Bet Limited), Copybet (53774, Copybet UK Limited), Kwiff (licensed by the Commission, operated by Spryme Ltd), Lottoland UK, Fitzwilliam Sports, Kalooki Sportsbook (57730, Kalooki Sports Book Ltd), Silkbet (101183, three remote licences held by Silkbet Limited since 7 May 2026) and Greenlight Bet, whose site at the snapshot date showed a “Launching Soon” placeholder and is described qualitatively only.

The operators, one by one

What follows is a working write-up of each operator on this page. The licence, the welcome offer on the operator’s own terms, the app, the safer-gambling toolkit and the small print, and a verdict the comparison stands behind. The shelf is in the same order as the ranking.

bet365

bet365 sits at the top of the ranking on the strength of three things. The depth of market on football, racing and US sport; the live-streaming rights that turn the in-play product from a screen of numbers into something the bettor can watch; and Bet Builder+, which combines markets from one match into a single bet pre-match and in-play. Super Boosts, Winnings Boosts on Bet Builders and selected singles, and daily Bet Boosts sit alongside. The app is the most-downloaded sports betting app in the UK by App Store ranking, and the listing names Face ID login on supported devices; the funding options are debit card, PayPal and Apple Pay. The licence is held by Hillside (New Media) Limited, and bet365 is the official global betting partner of the UEFA Champions League. The verdict: the strongest all-rounder in the British market for a punter whose betting is football-led and who wants live streaming on the same screen.

888sport

888sport’s UK site runs on a Commission licence held by 888 UK Limited. The offer is broad: pre-match and in-play betting, Cash Out, Bet Builder, racing streams, BetFinder form tools, a live bet feed and daily boosted odds on Premier League and racing. The welcome offer is described on the operator’s own terms as part of the broader product; the small print is the small print. The verdict: a broad mid-market sportsbook for a punter who wants racing streams and a daily boosted-odds feed without paying a premium for the headline names.

BetVictor

BetVictor runs on a Commission licence held by BV Gaming Limited and is best known on the racing side of the British market. Best odds guaranteed on UK and Irish racing is the centrepiece; enhanced live race streaming, BetFinder for racing bets and Smart Stats sit alongside. The football book is full rather than specialist. The verdict: the British shortlist’s strongest racing-led book, with a football book broad enough to make it a year-round account rather than a Cheltenham-only one.

BoyleSports

BoyleSports is an Irish-heritage brand running on a UK licence held by Boylesports Enterprise. The sportsbook is strong on horse racing and football; the welcome offer for UK players is £20 in free bets for a £10 qualifying bet, with Irish players seeing €30 in free bets for a €10 bet. The verdict: the strongest racing and football pair in the mid-market, with a welcome offer that turns a £10 stake into a £20 free-bet headline — read the minimum-odds and expiry lines before claiming.

Spreadex

Spreadex runs a sportsbook and a financial spread betting operation under the same brand, on a Commission licence held by Spreadex Limited. The sportsbook sits alongside the FCA-regulated spread betting side; losses on the financial side can exceed the deposit, and that risk sits separately from the Commission’s social responsibility code. The verdict: the only bookmaker in this ranking whose offer runs on two regulators; a punter looking for sportsbook-only depth has stronger choices, and a punter curious about financial spreads has the same brand’s other half.

Hollywoodbets

Hollywoodbets is a South African heritage brand running on a UK licence held by Hollywoodbets International UK Limited. The sports welcome offer is a stake-back free bet of up to £30 on the first qualifying losing accumulator — £10 stake or more, three or more legs, odds of 4/1 or greater, settled within seven days, one free bet per customer. The verdict: the welcome offer is one of the more transparent stake-back structures in the ranking; the small print is the rule and the rule is the small print.

Matchbook

Matchbook is the only betting exchange in this ranking, running on a Commission licence held by Triplebet Limited under the remote betting intermediary category. Punters back and lay against each other and the operator takes a commission on net winnings rather than running a margin on the price; the markets are deep on Premier League and the bigger horse racing meetings and thinner further down the card. The Betdaq brand was acquired by Triplebet Limited; Betdaq accounts do not transfer to Matchbook. The verdict: a different product rather than a substitute, and the strongest choice for a punter who lays as well as backs and wants the price the exchange writes rather than the price the bookmaker offers.

Dabble

Dabble is a Commission-licensed sportsbook held by Dabble Sports UK Ltd with a social-leaning product and a simple welcome. The offer is bet £10, get £10 in free bets on a first deposit, with minimum odds applying, a 7-day free bet expiry and the stake not returned. The verdict: a small welcome offer in headline terms and a clearer-than-most set of conditions; the social features suit a punter who wants to share their slips without giving up the licence.

Octobet

Octobet runs on a Commission licence held by Octopus Game Limited. The sportsbook welcome offer is 50% back as a free bet up to £50, plus a £10 casino bonus; the mixed-product element sits inside the Commission’s January 2026 rule change, which has banned mixed-product promotions, and the operator’s terms describe the offer as a sportsbook welcome with a casino bonus on the side. The verdict: a small-stake punter looking for a percentage-back welcome on a single deposit will read the headline and the cap; a punter looking for a casino-and-sportsbook bundle will read the same line in different terms.

Bet Ahoy

Bet Ahoy runs on a Commission licence held by Bet Ahoy Ltd. The welcome offer is bet £10, get £10 in free bets, split into a £5 sports free bet and a £5 acca free bet. The verdict: a smaller bookmaker with a slim welcome offer; the headline is two free bets rather than one, and the punter decides whether the structure suits the betting they do.

Geoff Banks

Geoff Banks runs on a Commission licence held by GB Sports Advisors Limited, with live in-play prices and ante-post markets on future events.

Safer-gambling links run to GambleAware, GamCare, GamStop and BetBlocker. The verdict: an esports-rooted sportsbook with a popular acca builder and the usual safer-gambling tools; a punter betting on esports and football in equal measure has the wider bookmaker set, a punter betting on esports primarily has a focused option.

BetMGM UK

What the comparison found, in one paragraph

Ten names off the Commission’s register, on each operator’s own published terms, with the licence and the welcome offer described the way the operator’s site describes them. A ranking that puts bet365 at the top because of depth of market and live streaming; BetVictor, BoyleSports and Hollywoodbets running close behind on the racing-and-football pair the British punter splits their time across; Spreadex as the only dual-regulator brand; Matchbook as the only exchange; Dabble, Octobet and Bet Ahoy as smaller-stake welcome offers whose conditions are the headline; Unibet, BetMGM UK, 10bet, Betmaster, BetWright, London.bet, Copybet, Kwiff, Lottoland UK, Fitzwilliam Sports, Kalooki Sportsbook, Silkbet and Geoff Banks as the rest of the licensed set, each on its own terms. The arithmetic at the close: a 1.90 / 1.90 illustrative market carries a margin of about 5%, and the punter’s price is the rest.

Frequently asked questions

Where can I compare online betting odds?

The most direct answer is to put the same selection into two or three of the licensed operators on this page and read the price in the same format. Decimal odds are the comparison’s native language; a £10 stake at 2.50 returns £25, and the difference between 2.50 and 2.55 on the same selection is what an odds comparison surfaces. The licensed set is on the Commission’s public register, and any odds-comparison site the punter uses is only as good as the operators it lists.

How do I compare betting odds?

Convert to one format first — decimal is the easier — and put the prices side by side on the same selection. A price of 5/1 in fractional is 6.00 in decimal; a price of 11/4 is 3.75; evens is 2.00. The higher decimal price is the better price at the same stake, and the calculation is return = stake × decimal odds. The bookmaker’s margin sits inside every price, and the calculation further down this page shows what that margin looks like at an illustrative 1.90 / 1.90 market.

How do I compare betting site features?

Start with the licence, because the licence is the floor. The Commission’s public register lists every operator on this page, and the licence is the test of who is in the licensed set. Beyond that, the comparison is a matter of what the punter bets on (racing, football, esports, the niche), how much they stake (small or large), and which features matter to them (live streaming, bet builder, cash out, exchange-style back-and-lay). The ranking above is one ordering; the operator write-ups are where the punter decides.

How can I check that a bookmaker holds a Gambling Commission licence?

The Commission’s public register is the whole test, searchable by business name, trading name, domain or account number. Every brand on this page lists its account number; the operator’s own terms page and the register should agree. A licence is not a marketing claim — it is a register entry — and the register is the place a punter checks it.

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

In decimal odds, return = stake × decimal odds, and net profit = stake × (decimal odds − 1). A £10 stake at 2.50 returns £25 (£10 stake plus £15 profit). For a combination bet the odds of the legs multiply into one price; a double of 2.50 and 3.00 is a combined price of 7.50, and a £5 double returns £37.50. The British punter meets fractional odds on the racing side; the conversion is a/b → a ÷ b + 1, so 5/1 is 6.00 in decimal and 11/4 is 3.75.

What is the bookmaker’s margin and how can I see it in the odds?

The margin is the share of every pound staked on a market that the bookmaker keeps, averaged across all outcomes. The payout share is what is returned to the punter, and the two add up to 100%. The arithmetic is payout share = 1 ÷ (1/odds₁ + … + 1/oddsₙ) over every outcome, and margin = 1 − payout share. At an illustrative 1.90 / 1.90 the implied probability per outcome is roughly 52.63%, the payout share is about 95.00%, and the margin is about 5.00%. A real margin varies by operator, market and event, and a tighter margin is a better price at the same selection.
