Most “online betting sites comparison” pages are bookmaker advertisements in a table shape. This one is not. It compares ten online betting sites that actually hold a Gambling Commission remote licence on what their own published terms say, and it closes each block on what those terms cost the bettor. Comparison on this page means: a licence number a reader can verify on the public register; the odds format and the margin built into those odds; the deposit, free-bet and bonus mechanics in plain English; and the safer-gambling machinery every licensed operator has to carry. Where the roster of sites meets the rules around them, the meeting point is where this page lives.

Current as of 27 October 2026, checked against the Gambling Commission’s public register and each operator’s own UK site.

Shortlist at a glance: the ten licensed bookmakers on this page

A licensed bookmaker in Great Britain is one whose name appears on the Gambling Commission’s public register against a holder of a remote general betting licence (or a remote betting intermediary licence for an exchange). Ten sites meet that test on the register as of the date stamped above; the ranking that follows is not issued by the Commission and is not a recommendation. It ranks them on what this page argues matters: licence transparency, the operating-company name printed on the UK site, and the cost of their headline offer to a real bettor rather than the marketing.

Several brands on the roster run under the same parent. Ladbrokes sits under LC International Limited within the Entain group; Paddy Power and Betfair are run by PPB Counterparty Services Limited; Matchbook and Betdaq are now both under Triplebet Limited. Reading the table as ten independent operators is the first mistake a comparison makes. They are ten sites, fewer groups, and the licence number is the test of who actually holds the permission.

What “licensed” means in Great Britain, and what it does not

A bookmaker serving customers in Great Britain needs a Gambling Commission licence wherever it is based. The Gambling (Licensing and Advertising) Act 2014 closed the previous loophole that let operators run from overseas jurisdictions for a British customer base. The Commission’s public register is the whole test of who holds a licence. It can be searched by business name, trading name, domain or account number, and an account number on the register is conclusive — no print, screenshot or footer claim substitutes for it. A Curaçao, Isle of Man or Gibraltar licence is not a substitute for a Commission licence; several of the operators on the roster are based in Gibraltar for tax reasons, but each one is named on the register against a UK account.

The Act does not cover Northern Ireland. Northern Ireland runs on older legislation and a bookmaker serving customers there needs a different licence; never write that a GB licence regulates Northern Ireland, and never write that a single brand is “the only” licensed one. There is no state monopoly, no cap on the number of licences and no statutory list of permitted markets — what an operator may offer is set by its licence category and its own conditions.

The two paths into the same register are remote general betting standard (real events) for a fixed-odds bookmaker and remote betting intermediary for a betting exchange. A spread-betting brand whose contracts are on financial markets is regulated by the Financial Conduct Authority instead; Spreadex runs both books, fixed-odds under the Commission and financial spread betting under the FCA, and states that spread betting losses can exceed the deposit. That warning is not on a fixed-odds slip because on fixed odds it does not apply; it is on a spread slip because there the loss is not capped at the stake.

Mobile and app: the operating surface most readers actually use

The browser is the fallback, not the front door. A comparison that ranks bookmakers on the desktop product they offered in 2015 reads as out of date the day it ships. What matters is whether the app loads fast, holds a login, settles in-play without lag, and exposes the bet builder, the cash-out button and the live stream where the operator offers one. Betfair’s app carries in-play, Bet Builder, free live streaming of UK and Irish horse racing and football, and a 90 Minute Payout market on selected football fixtures; bet365 carries in-play, live streaming of events worldwide, Bet Track, Match Live and a Live Golf Tracker, plus Bet Builder+ for combining markets from one event pre-match and in-play; Midnite’s app carries in-play, an acca builder, popular accas and price boosts, with maximum-stake limits printed next to each boost. These are not interchangeable. A reader who wants to back and lay on the same fixture needs an exchange, and only two on this list run one.

The iOS rating is a noisy proxy, not a verdict. Ladbrokes’ GB App Store listing is rated 4.66 from 101,255 ratings, which is a useful number when read as scale of users who bothered to leave one; it is not a quality mark — bookmaker apps are routinely trashed in reviews by customers who lost and rated, and the rating aggregates that signal without separating it. Use it as evidence that the app is downloaded and used, not as a verdict on its quality.

Face ID login and Apple Pay funding are common across the licensed set. bet365 accepts debit card, PayPal and Apple Pay, and supports Face ID login on supported devices; LiveScore Bet accepts debit cards, Apple Pay, PayPal, Pay by Bank through Open Banking and Revolut Pay; Midnite accepts Visa, Mastercard, Apple Pay, Google Pay and Trustly. The licensed set broadly agrees on what the funding rails look like, and broadly diverges on which specific wallets and instant-bank rails each has chosen. A reader who is locked into one wallet — Revolut users, Google Pay defaulters, Open Banking-only bank account holders — should check the operator’s banking page before opening the account.

Bet types and odds: what a price actually pays

A decimal price of 2.00 means a £10 stake returns £20 — the £10 stake plus £10 profit. Fractional odds of 1/1 (evens) mean the same. 5/1 fractional is 6.00 decimal: 5 divided by 1 plus 1. A reader who bets only in fractions and a reader who bets only in decimals are reading the same market; this comparison’s table cells use decimal because the conversion is mechanical and the reading is unambiguous. Fractional 5/1, decimal 6.00, return on £10 is £60. The two formats carry identical information; they are spelled differently.

The bookmaker’s margin is the share of every pound staked that the book keeps on average across all outcomes of one market. For an illustrative two-way market at decimal odds 1.90 / 1.90, the payout share works out as 1 ÷ (1/1.90 + 1/1.90), which is 1 ÷ 1.0526, or roughly 0.95; the margin is therefore about 5%, give or take a fraction. Stated as a band rather than a single figure: depending on how a book rounds its prices, the margin on a market priced symmetrically at 1.90 / 1.90 will sit between roughly 4% and 6% — a tight book at the bottom of the band, a typical book in the middle, a generous-to-the-punter book at the top. The same market at 1.85 / 1.85 widens that band by a couple of points; the same market at 1.95 / 1.95 tightens it. The bookmaker’s margin is not the stake the bettor loses on any single bet — it is the average the book earns across a large number of bets at those prices.

The single bet, the double, the treble and the accumulator (acca) multiply. A double at 3.00 and 4.00 has combined odds of 12.00, so a £10 stake returns £120. A four-fold acca at 2.00, 3.00, 4.00 and 5.00 has combined odds of 120.00, and a £10 stake returns £1,200 if all four legs win. Each added leg increases the price and decreases the probability all four legs land; the multiplication is real and so is the compounding chance of one leg letting the bet down. That is the bet builder’s appeal and its risk in the same line. Each-way is two bets of equal stakes: a £10 each-way stake is £20 total, half on the win and half on a place at the place terms printed for that race. A Lucky 15 is 15 bets (4 singles, 6 doubles, 4 trebles, 1 four-fold accumulator) and the unit stake multiplies by 15, so a £1 Lucky 15 costs £15 to place.

The exchange is a different market entirely. On a fixed-odds book the bookmaker sets the price and the bettor backs or lays at that price; on an exchange like Betfair or Matchbook, punters set the price and back or lay against each other, with the exchange taking a commission on net winnings. Matchbook runs on that model under a remote betting intermediary licence held by Triplebet Limited; Betfair runs a sportsbook and an exchange under the same parent. The Betdaq brand has been acquired by Triplebet Limited and Betdaq accounts will not transfer to Matchbook. A reader comparing exchanges compares commission rates and liquidity, not margins, because there is no margin to compute — the book on an exchange is the spread between the best back price and the best lay price.

Sports and tournaments: what the roster covers

Football dominates the British fixed-odds market by turnover and by handle. Premier League, Championship, the FA Cup and the Scottish professional divisions carry the deepest books; the Champions League and the major European leagues sit underneath. bet365 is the official global betting partner of the UEFA Champions League, which is not a regulatory marker but a commercial one — it tells a reader which brand the tournament and its clubs accept money from.

Horse racing is the second pillar of British betting and a separate licensing consideration. Off-course pool betting on horse or dog racing is its own licence category and duty, and an operator offering only fixed-odds horse racing may be on a different licence than one offering Premier League football. The Irish and UK horse-racing calendars drive most of the year: the Cheltenham Festival in March, the Grand National meeting in April, Royal Ascot in June, the Galway Races in July-August, the Punchestown Festival in April-May. Bar One Racing sponsorships at Dundalk, Fairyhouse, Navan, The Curragh, Curraheen Park and Cork mark it as an Irish independent with racing as a flagship, and its UK-facing product is shaped around the Irish and UK racing calendar.

Golf carries sustained interest across the four majors, the Ryder Cup, and the week-to-week PGA Tour and DP World Tour schedules. The Open Championship in July is the British centre of gravity; the Masters in April, the PGA Championship in May and the US Open in June complete the majors calendar. Tennis runs almost year-round on the ATP and WTA tours with the four Grand Slams as peaks. Boxing, darts, snooker and cricket each carry their own seasonal cadence. A reader who bets only on one sport should rank bookmakers on that sport’s coverage and not on the generalist pitch — depth on a niche is not the same as breadth across the catalogue.

In-play markets are offered by every fixed-odds bookmaker on this list. The Commission’s rules do not require them and do not forbid them, and the controls are operator-level. A reader who bets in-play is betting against a market that moves faster than the slip can be confirmed; the bet builder, the cash-out button and the live tracker on bet365 are tools for that market, not a substitute for the discipline it requires.

The ranking: ten sites compared on what their own terms say

The ranking that follows is editorial. It is based on what the operators’ own published terms say, the betting products they offer and the licence transparency each one carries on its UK-facing site. It is not the Commission’s view and is not a recommendation to sign up.

1. bet365 — official partner of the UEFA Champions League

bet365 is the official global betting partner of the UEFA Champions League, and the GB App Store listing describes it as the most downloaded sports betting app in the UK. Its app carries in-play betting, live streaming of events worldwide, Bet Track, Match Live and a Live Golf Tracker. Bet Builder+ combines markets from one event into a single bet, available pre-match and in-play. The operator offers Super Boosts, Winnings Boosts on Bet Builders and selected singles, and daily Bet Boosts.

Accounts fund by debit card, PayPal and Apple Pay, with Face ID login on supported devices. The product surface is the widest on this list: in-play, live streaming across multiple sports, a bet builder for football and other sports, multiple boost formats, and a tracker layer for following bets in play. The cost of the breadth is the same as it is on any generalist — the specialist product on a niche sport tends to be thinner than a specialist’s. For a reader whose betting is the Premier League, the Champions League and the major US sports, bet365 is the strongest single-app proposition on this list. For a reader whose betting is lower-division English football, or Irish horse racing specifically, the proposition is solid but not differentiated.

2. Betfair — sportsbook plus exchange under PPB Counterparty Services Limited

Betfair runs two products on one licence: a sportsbook under PPB Counterparty Services Limited and an exchange under the same parent. The sportsbook offers in-play betting, Bet Builder, free live streaming of UK and Irish horse racing and football within the app, and a 90 Minute Payout market on selected football fixtures. The exchange lets a reader back and lay on the same event with other punters rather than with the house, which is the proposition an exchange actually is.

A reader who wants both — the sportsbook for the bet builder and the streaming, the exchange for the back-and-lay and the in-running trading — gets them both on one account. A reader who wants only the sportsbook has better pricing on a pure bookmaker because the sportsbook’s margin funds the exchange’s commission discount elsewhere. Betfair and Paddy Power share the same licensee and the comparison treats them as one operator on two fronts, not as two independent operators. For a reader who values the exchange’s liquidity and price on Premier League football and the major horse racing meetings, Betfair is the obvious pick. For a reader who bets singles only and never backs-and-lays, the sportsbook’s headline offer is comparable to a mainstream bookmaker.

3. Unibet — operating since 1999 under Platinum Gaming Limited

Unibet states it has operated since 1999, and its UK site is run by Platinum Gaming Limited under account 45322. Its safer-gambling tools include deposit limits, a Player Profile test, product restrictions and self-exclusion, with live chat support and links to BeGambleAware, GamCare, GAMSTOP, Gambling Therapy and the BGC. The product surface is broad, the safer-gambling machinery is fully wired and the operator’s UK site prints its licence prominently.

For a reader who values a long track record and a fully disclosed safer-gambling toolkit, Unibet is the strongest profile on this list on those two counts. The product surface is competitive but not differentiated from bet365 or Betfair. The key question for a reader is whether the safer-gambling machinery is enough on its own — it is necessary, not sufficient — and whether the sportsbook’s pricing beats the leader’s on the markets the reader bets.

4. Ladbrokes — Entain group, large user base

The Ladbrokes Sports Betting App is published by Entain Operations Limited and is rated 4.66 from 101,255 ratings in the GB App Store. The scale of users who left a rating is the signal; the rating itself aggregates too many motives to read as quality. Ladbrokes sits under LC International Limited within the Entain group, alongside Coral; treating Ladbrokes and Coral as two independent operators is the error this list corrects for. The product surface is generalist, the high-street brand recognition is high, and the app’s user base is large.

A reader who values brand familiarity and high-street presence gets a familiar experience; a reader who wants the sharpest in-play price or the deepest exchange gets a sharper product elsewhere. The Ladbrokes and Coral pair are two sites, one group, one licence per group.

5. BoyleSports — £20 in free bets for a £10 qualifying bet

BoyleSports’ sports welcome offer for UK players is £20 in free bets when a £10 bet is placed, with €30 in free bets for a €10 bet for Irish players. The UK-facing offer is the same shape as every other bookmaker’s welcome offer: a stake threshold, a free-bet payout, a window in which to use it. The value of a £20 free bet whose stake is not returned is set by where the bettor places it and at what price, not by the headline £20 figure.

For a UK reader comparing welcome offers, BoyleSports is in the middle of the band: £20 in free bets for £10 down is competitive but not unusual. For an Irish reader, the offer is sized in euros and tied to the Irish market, and the comparison is to other Irish-facing bookmakers rather than to UK-facing ones.

6. QuinnBet — free-bet terms spelled out in plain English

QuinnBet free bets are valid for 7 days from credit and can be used on any market at odds of 1/2 (1.5) or greater, with maximum odds of 50/1; straight accumulators are allowed but Trixies, Patents and Yankees are not. The terms are the clearest on this list: a 7-day window, a minimum price of 1.5, a maximum price of 50, and an explicit list of bet types that are and are not eligible.

For a reader who values clarity, QuinnBet is the easiest offer on this list to read; the cost is the restrictions. A bettor who wants to place a system bet like a Patent or a Yankee cannot use a QuinnBet free bet for the qualifying stake; a bettor who wants to place a high-price acca cannot exceed 50/1. These are not unusual restrictions — they are typical of the market — but QuinnBet is the operator that prints them clearly.

7. Midnite — fresh UK licence under Midnite Limited

Midnite’s site cites Gambling Commission licence 101839 and shows in-play events, an acca builder, popular accas and price boosts with maximum-stake limits. The operator is one of the newer entrants on this list, the licence is recent, and the product is shaped around a younger audience: in-play, acca builders, price boosts. Funding is by Visa, Mastercard, Apple Pay, Google Pay and Trustly; safer-gambling links run to GambleAware, GamCare, GamStop and BetBlocker.

For a reader who values a fresh product surface and a recent licence, Midnite is worth opening; the product is competitive with the major generalists on in-play and acca, and the funding rails include Apple Pay and Google Pay. The product’s relative youth is also its relative untested — fewer years of in-play stability, fewer settled disputes, fewer published complaints upheld or rejected by an ADR body.

8. NetBet — Daily Boosts, Profit Boosts, Bet Builder with instant dynamic odds

NetBet Sport offers Daily Boosts, Profit Boosts and free bet offers, a Bet Builder with instant dynamic odds, and sports stats for major leagues. The product is generalist, the boost formats are layered, and the bet builder’s “instant dynamic odds” — the price updating as selections are added and removed — is a useful feature for a reader who builds singles into combined bets across markets.

For a reader who values a layered boost structure (daily boosts on selected markets, profit boosts on accas, free-bet offers across the calendar), NetBet is competitive with the rest of the generalists; the product is not differentiated by a single standout feature, but it is competitive across the catalogue.

9. LiveScore Bet — debit cards, Apple Pay, PayPal, Pay by Bank, Revolut

LiveScore Bet accepts debit cards (Visa and Mastercard), Apple Pay, PayPal, Pay by Bank (Open Banking) and Revolut Pay. The funding surface is the widest on this list: five distinct rails, including the Open Banking rail that reads directly from a bank account and the Revolut rail that serves the Revolut user base specifically. The product surface is generalist and not differentiated; the funding surface is the proposition.

For a reader who is locked into Revolut, or whose only bank account is Open Banking-only, LiveScore Bet is the operator whose funding rails match that reader. For a reader who uses a debit card and PayPal, the rails are no different from the rest of the roster.

10. Bar One Racing — Irish independent with horse racing sponsorships

Bar One Racing has rebranded as BAR 1 Betting, an Irish independent bookmaker with shops across Ireland and horse racing sponsorships at Dundalk, Fairyhouse, Navan, The Curragh, Curraheen Park and Cork. The Irish racing calendar is the centre of gravity: Irish racing sponsorships are a marketing choice, not a coverage statement, but they are an honest signal that the operator knows Irish racing better than the average generalist.

For a reader whose betting is Irish horse racing specifically, BAR 1 Betting is worth a look; for a reader whose betting is Premier League football, the proposition is generalist and undifferentiated. The UK-facing product is on a Commission licence and the comparison to the rest of this list holds on those terms.

Matchbook — exchange under Triplebet Limited, with Betdaq now under the same group

Matchbook runs a betting exchange on a remote betting intermediary licence held by Triplebet Limited. The Betdaq brand has been acquired by Triplebet Limited, and Betdaq accounts will not transfer to Matchbook — the two brands are now under one operator, not two competing exchanges. The exchange product lets a reader back and lay on the same event with other punters; commission on net winnings is the operator’s revenue.

For a reader who trades in-running on Premier League football or the major horse racing meetings, Matchbook is one of two UK-licensed exchange options (Betfair is the other); for a reader who only places singles, the product is wrong on a comparison that lists fixed-odds bookmakers. The proposition is for the back-and-lay user, not the singles-only user.

Bonuses and free bets: what an offer is actually worth

The £20 in free bets for a £10 qualifying bet is the same headline as every other bookmaker’s welcome offer, and the headline is where the comparison usually stops. The comparison this page runs does not stop there. Three numbers tell a reader what an offer is worth: the qualifying stake and minimum odds; the wagering requirement on bonus funds (if any); the expiry window and the eligible bet types.

The 10x wagering cap on bonuses took effect on 19 January 2026 under Commission promotion rules. A £10 bonus at the cap requires £100 of qualifying bets; a £10 bonus at 50x (the old market rate) required £500 of qualifying bets. Whether the cap applies to free bets with no wagering condition, and any cap on the money value of a bonus, are not established — write “the cap applies to wagering requirements on bonuses” and not “the cap applies to all free bets”. Mixed-product promotions — an offer that requires gambling on two or more product types such as betting, casino, bingo and lottery, for example “bet on football to get free spins” — are banned under the same rule. A reader who sees an offer that gates free spins or casino play behind a sportsbook bet should not sign up to claim it; the offer is non-compliant.

The free bet whose stake is not returned is the standard shape. A £20 free bet placed at decimal odds of 4.00 returns £60 in profit — the £20 stake is forfeit, the £60 profit is paid. The same free bet at 2.00 returns £20 in profit; at 10.00 returns £180. The higher the price, the higher the return; the lower the probability of landing, the lower the hit rate. A bookmaker’s 7-day expiry (QuinnBet’s terms) is a window the bettor chooses how to use, not a window the bookmaker offers out of generosity — a bettor who lets the free bet expire wastes it.

The each-way free bet is two bets of equal stakes and pays on both win and place. A £10 each-way free bet is effectively £20 of stake split across win and place; the place terms are the race card’s printed place terms. A free bet on a non-runner is governed by the operator’s non-runner rule; a Rule 4 deduction reduces the price of a winning bet when a runner is withdrawn. These are the bookmaker’s own rules and they vary by operator; the comparison this page runs treats the rule as the operator’s choice and not as a uniform rule across the industry.

The welcome offer is not the only offer. Daily Boosts, Profit Boosts, price boosts with maximum-stake limits and acca insurance are recurring promotions across the generalists. A price boost lifts the price on a selected market for a limited window; an acca insurance refunds the stake as a free bet if one leg of an accumulator lets the bet down; a Profit Boost multiplies the winnings on a selected accumulator. Each is a marketing mechanism that shifts the price on a specific bet for a specific window; the cost to the reader is the same as any other bet at the boosted price, and the benefit is the better price for that bet.

Responsible gambling: what the licensed set has to offer

GAMSTOP is the national multi-operator online self-exclusion scheme and a mandatory licence condition for online operators since 31 March 2020. Periods are six months, one year, five years, or five years with auto-renewal; after the minimum period the exclusion stays in place for a further seven years unless the customer asks GAMSTOP to remove it. It covers online sites and apps; betting shops use a separate service. Every GB-licensed online operator takes part in GAMSTOP; an unlicensed brand does not. A reader who needs to self-exclude needs to be on a licensed site for the exclusion to apply across the licensed set.

The financial vulnerability check is in force since 30 August 2024 under LCCP condition 3.4.4. It applies to licensed remote betting when a customer’s deposits minus withdrawals exceed £150 in a rolling 30 days (since 28 February 2025). It is a public-record check — for example bankruptcy or county court judgments — not an income check and not a credit reference check. The financial risk assessment (the “affordability checks” of the press) is announced in a staged plan (Commission article of 7 July 2026), with no start date. A reader who hears about “affordability checks” should know the financial vulnerability check is in force and the broader risk assessment is not yet started.

Deposit limits (RTS 12): operators must offer a gross deposit limit on a fixed time frame. The first changes applied since 31 October 2025; a second phase was postponed to 30 September 2026. Whether the second phase is live is not established. There is no state-set deposit or loss ceiling for betting — limits are the customer’s choice within the operator’s product surface. The deposit limit is the bettor’s tool, not the state’s. Unibet offers deposit limits, a Player Profile test, product restrictions and self-exclusion; Midnite links to GambleAware, GamCare, GamStop and BetBlocker; LiveScore Bet’s safer-gambling surface is shaped by the operator’s own page. The licensed set broadly agrees on what the safer-gambling machinery looks like; the surface differs.

Help: GamCare runs the National Gambling Helpline; GambleAware funds treatment and education; the NHS runs gambling clinics in some regions; Gamblers Anonymous runs peer-support meetings. A reader who needs help should reach the National Gambling Helpline directly rather than wait for an operator’s customer service to signpost it.

Offshore, illegal and the loss of British protections

An unlicensed brand offering facilities in Great Britain is operating illegally. The Gambling Act 2005 (as amended by the 2014 Act) makes it an offence under section 33 to provide gambling facilities in Great Britain without the licence the Act requires. The offence is aimed at the operator; no offence aimed at a customer who merely bets on an unlicensed site was found. State the cost to the customer honestly: 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, not bound by the £150 vulnerability check. The bettor who bets on an unlicensed site is not breaking the law and is not “safe”; the bettor is unprotected in the ways British law protects bettors.

Enforcement is disruption, not blocking: cease-and-desist notices, search-engine referrals, work with registrars, hosts and payment providers. The Commission has been given, or is about to receive, court-order DNS blocking powers — write “is being given, or is about to receive” and not “is operating”. Honest framing: licensed = checks, limits, GAMSTOP, bonus cap, but also verification before the first bet; unlicensed = none of those protections and possible loss of funds. Neither is “the safe choice” by default.

Tax: who pays, and who does not

The player pays no tax on betting winnings in Great Britain. General information, not tax advice; a professional gambler should ask HMRC or an adviser. General Betting Duty is the operator’s tax on gross profits, currently 15%; from 1 April 2027 a new remote betting rate of 25% applies within it, while remote bets on UK horse racing, bets on self-service betting terminals in licensed premises, pool betting and in-person betting stay at 15% (HM Government policy paper of 26 November 2025). Until 1 April 2027 the remote rate stays at 15%.

Whether operators pass duty on through odds is not established. Never write that the player is charged duty; never write that the player is not charged duty on the way the operator prices. The bettor sees the price and pays the stake; the duty sits between the operator and HMRC.

The Commission’s statutory levy is a separate charge, not a tax. It funds the regulator and is paid by the operator. A reader comparing bookmakers does not need to know the levy number; a reader writing to their MP about gambling policy does.

Advertising, sponsorship and the 9pm watershed

Advertising is not licensed by the Commission; it runs through the CAP Code (non-broadcast) and BCAP Code (broadcast), enforced by the ASA, alongside the LCCP marketing conditions. CAP Code section 16: marketing must be socially responsible, must not be of strong appeal to under-18s, and no one who is or seems to be under 25 may be featured gambling or play a significant role (with an exception for marketing placed where a bet can be made directly). That rule concerns who may appear in the advertisement, not who may bet.

“Whistle-to-whistle” is an industry code, not law: since 1 August 2019 betting advertisements are not shown on TV from five minutes before a live sporting event to five minutes after it, before the 9pm watershed (horse and greyhound racing excluded). The Premier League clubs’ withdrawal of gambling sponsorship from the front of matchday shirts (from 2026/27; sleeves and hoardings remain) is voluntary, not law. Operators are responsible for marketing by their affiliates.

Where the comparison actually pays off

Ten sites sit on the register; one is an exchange; one is a newer entrant on a fresh licence; one is an Irish independent with racing at its centre. The General Betting Duty rise in 2027 will reshape margins on remote bets and the cost will land somewhere — the comparison this page runs is honest about that and will need to be re-stamped next year. The 10x bonus cap and the £150 vulnerability check are the two rule changes that have already changed what a bettor sees at a licensed site in 2026.

The honest question is not “which is the best” — that is the marketing question, and ten sites cannot be one best — but which one fits which reader, at what cost, on which sport, with which safer-gambling machinery wired up. A reader who backs and lays on the Premier League in-running picks Betfair or Matchbook; a reader who wants a wide product surface and live streaming picks bet365; a reader who values a fresh product and a recent licence picks Midnite; a reader who wants Irish racing depth picks Bar One Racing. The comparison that names the brand and the cost is the comparison a reader can use.

Frequently asked questions

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

The Commission’s public register can be searched by business name, trading name, domain or account number, and an account number on the register is conclusive. The domain extension proves nothing — licensed operators use .com as well as .co.uk. No screenshot, footer claim or third-party listing substitutes for an account number on the register itself.

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

For decimal odds, return = stake × odds, and net profit = stake × (odds − 1). For example, a £10 stake at decimal odds 4.00 returns £40 and profits £30. For a combination bet the odds of the legs multiply into one price, so a double at 3.00 and 4.00 has combined odds of 12.00 and a £10 stake returns £120.

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

For a market with n outcomes, payout share = 1 ÷ (1/odds₁ + … + 1/oddsₙ), and margin = 1 − payout share. For an illustrative two-way market at 1.90 / 1.90, the payout share is roughly 95% and the margin is roughly 5%, give or take rounding. Stated as a band: typically between roughly 4% and 6% at those prices, tighter at 1.95 / 1.95 and wider at 1.85 / 1.85.

Which tools for controlling play does a licensed bookmaker have to offer?

Every GB-licensed online operator takes part in GAMSTOP (the national multi-operator self-exclusion scheme, six months to five years plus a seven-year tail) and offers deposit limits under the RTS 12 framework. Unibet’s published toolkit adds a Player Profile test, product restrictions and self-exclusion; the broader licensed set publishes comparable surfaces with different naming.

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

No tax is due on betting winnings in Great Britain (general information, not tax advice; a professional gambler should ask HMRC or an adviser). General Betting Duty is the operator’s tax on gross profits, currently 15% on remote bets; from 1 April 2027 a remote rate of 25% applies, while remote bets on UK horse racing, pool betting and in-person betting stay at 15%. The duty sits between the operator and HMRC; the bettor sees the price and pays the stake.
