Value betting is not a marketing label. It is a simple trade: a price the bookmaker offers, a probability you have formed of the outcome, and a stake whose size depends on the gap between the two. Get that gap right and the bet earns money over time. Get it wrong and the bookmaker’s margin does the work it was put there to do. This page is a working guide for that trade, written for a punter in Great Britain, and built on the prices, terms and licence positions the operators themselves publish.

The data below is current as of 27 October 2026 and was checked against the Gambling Commission’s public register. Prices and margins age faster than anything else on this page; where a specific price is given, it carries the snapshot date beside it. A market margin is a snapshot of one event on one bookmaker’s site at one moment and is not a permanent feature of that brand.

How value in a bet is built and how it is settled

A bet has a “value” when the price is bigger than the true probability of the outcome would justify. If a horse is a 1-in-4 chance of winning a race and the bookmaker offers decimal odds of 5.00, the price is generous: 5.00 implies a probability of 1 ÷ 5.00, or 20%, the same 1-in-4. A bet at 6.00 against the same horse is a 6-to-1 ticket against a 4-to-1 reality, and that 2-point gap is where value lives.

The trick is that this is an asymmetric exercise. The bookmaker’s job is to set prices that look generous enough to attract money on every outcome of the market, while keeping a margin. The punter’s job is to find prices that are more generous than the bookmaker’s own internal view of the race. The bookmaker’s view is unknown; the public price is the only thing either side can act on. Closing line value — the price on the market when the book closes — is the standard the betting literature uses to grade a bettor’s eye, because the closing price is the closest published approximation to a true probability the market will give.

Settling the bet is the easy part. For a single at decimal odds *o* and a stake of *s*:

• Return (the money back, including the stake) is *s × o*. A £10 single at 5.00 pays £50 if it wins.
• Net profit is *s × (o − 1)*, the return minus the stake. A £10 single at 5.00 returns £50, of which £40 is profit.
• A combination bet multiplies the legs: a double at 3.00 and 4.00 is a single price of 12.00, and a £5 double returns £60.

The bookmaker’s margin is invisible in any one of those numbers. It lives in the *spread* between the prices on every outcome of the market, and it is the subject of the next section.

What the bookmaker’s margin is and how to read it in a market

Take a three-runner horse race where the true probabilities are 50%, 40% and 10% — a market that adds to exactly 100%. A bookmaker wanting to keep a margin publishes prices that imply 60%, 50% and 20%, summing to 130%. The 30-point gap is the overround, also called the bookmaker’s margin or vig, and it is the cut the bookmaker takes on every pound bet on the race, before any individual bettor’s result.

The arithmetic is the same on a two-way market. Consider a football match with decimal odds 1.90 on the home win and 1.90 on the draw — the kind of line a bookmaker might publish for a closely priced fixture. The implied probabilities are 1 ÷ 1.90 = 52.63% on each side, summing to about 105.3%, and the margin is 1 minus that sum divided by 2 — about 2.63% per side, or 5.3% across the market. A 5% margin is a tight book for a major sport; smaller niche markets run 8% to 12%, and exotic markets more. The lower the margin, the more of every pound the bookmaker pays back to winning bettors, and the less the punter pays for being on the wrong side of the price.

A bookmaker’s margin is a snapshot, not a permanent figure. It changes by event, by market and by the time of day. The margin of the 1X2 market on the Manchester derby is not the margin of the over/under 2.5 goals on the same match, and neither is the margin on a League Two match the same evening.

How UK punters see a price and what the licence protects

British bookmakers publish prices in fractional form (5/1, 11/4, evens) and decimal form (6.00, 3.75, 2.00), and the two are interchangeable. A fraction of “X to Y against” means a probability of Y ÷ (X + Y), so 4 to 1 against is 1 ÷ 5, or 20%, with a decimal price of 5.00. A “3 to 1 on” price is the favourite, where the bookmaker pays £3 for every £1 staked and the stake is returned, with a decimal price of 4.00. The starting price (SP) is the price the horse starts the race at, fixed by the market; best odds guaranteed (BOG) is the bookmaker’s promise to pay the higher of the price you took and the SP.

The licence that matters in Great Britain is issued by the Gambling Commission, a non-departmental public body sponsored by the Department for Culture, Media and Sport, under the Gambling Act 2005. Northern Ireland is outside the Act and has its own older law, so “GB-licensed” is the correct framing. The Commission’s public register is searchable by business name, trading name, domain or account number, and it is the whole test of whether a brand holds a licence — no count of licensed operators is given here without a register access date, because the register changes weekly.

Two protections follow from the licence that matter to the value of a bet. First, since 19 January 2026, wagering requirements on bonuses are capped at 10x: a £10 bonus can require at most £100 of qualifying bets, and an offer that asks for more is in breach of the Commission’s promotion rules. Second, every GB-licensed online operator is a member of GAMSTOP, the national multi-operator self-exclusion scheme, with periods of six months, one year, five years, or five years with auto-renewal. The terms on which a bookmaker will pay out a winning bet — minimum odds, payment-method restrictions, time limits on free bets — sit on the operator’s own page, and the licence guarantees a complaints route and approved dispute resolution that an offshore site does not.

The ten bookmakers on the list and what each one says about value

The brands below are holders of a Gambling Commission remote licence. The order is the comparison’s own; the set is fixed by the public register, and the licence numbers and category labels are taken from it. Every one of these operators is a member of GAMSTOP. Some carry a single, narrow licence; others carry a remote general betting licence for real events alongside other categories.

The comparison reads across one band of facts. The licence number, the holder named on the register, and what the operator’s own terms say about the way prices and offers work for the punter. Where the operator’s own terms say nothing the page can quote, the cell carries a dash; that gap is the operator’s silence, not the comparison’s.

The shape of the table is the shape of the British market. Eight of the ten are remote general betting standard licences, one is a remote betting intermediary (an exchange), and one — Smarkets — runs on commission on settled bets rather than a margin baked into the price. For a value bettor, that single row is the most important distinction on the page: a betting exchange does not build an overround into every price the way a traditional bookmaker does, and the closest thing to “true” odds is what back and lay prices meet at in the middle of the order book.

The legal frame around a value bet in Great Britain

A punter placing a bet with a licensed operator in Great Britain pays no tax on winnings. General Betting Duty is the operator’s tax on gross profits, currently 15%, rising to a 25% remote rate from 1 April 2027 within it. The player is not charged duty. A professional gambler — one whose betting is a trade, not a pastime — should ask HMRC or an adviser, because the position is different for trade.

The minimum age to bet is 18. A licensed operator will verify name, address and date of birth before the first deposit or the first free bet, so anonymous play is not on offer at any GB-licensed site. Since 30 August 2024 a financial vulnerability check applies to remote betting when a customer’s deposits minus withdrawals cross £150 in a rolling 30 days, and the check is a public-record check (bankruptcy, county court judgments), not an income check or a credit reference check. The Commission’s own plan for fuller financial risk assessments was announced on 7 July 2026, in a staged timetable with no start date.

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 by the ban. There is no state-set deposit ceiling, no state list of permitted payment methods and no statutory rule on cryptocurrency deposits at licensed operators — limits and accepted methods sit on the operator’s own terms.

A GB-licensed operator is not the only kind of betting site a UK punter can technically reach. The point of consumption rule, in force since the Gambling (Licensing and Advertising) Act 2014, makes a Commission licence compulsory for any operator whose remote facilities are used in Great Britain, regardless of where the operator is based. A Curaçao or Malta licence is not a substitute. Playing on an unlicensed site is not a criminal offence aimed at the customer, but it is also not under the Commission’s protection: no GAMSTOP coverage, no Commission complaints route, no approved dispute resolution, no 10x bonus cap, and no recourse if the operator decides not to pay. Honest framing: licensed means verification, limits, the bonus cap and the dispute route; unlicensed means none of those, and a real risk the money is hard to get back.

How each operator on the list treats a value punter

The list below is a closer look at each brand, with the specifications the comparison above does not have room for and a verdict at the foot. The verdict is the page’s own judgement, drawn from the operator’s own terms and from the licence position; it is not a marketing line.

Fitzdares — sport-by-sport in-play and antepost depth

Fitzdares is one of the smaller names on the list and uses that scale to publish a long, narrow book rather than a thin, wide one. The app’s published offering — cash out, accumulators, Lucky 15s, specials and antepost markets across horse racing, football, tennis, rugby, cricket, golf and American football, with in-play live odds — is the kind of menu a value punter with a niche can use, because the prices on a sport other than football are where the margin is widest and the edge is sharpest. Licence: account 400 (Fitzdares Limited).

The verdict: a strong second book for the punter who has a primary account elsewhere and wants a deeper antepost or in-play price on a sport the bigger books under-cover. For a beginner, the menu is too wide for the brand’s size and the in-play depth on football is the part most exposed to thin liquidity.

NetBet — boosts and a Bet Builder for the accumulator punter

NetBet’s published features are a stack of price enhancements: Daily Boosts, Profit Boosts, free bet offers, a Bet Builder with instant dynamic odds, and sports stats for the major leagues. That is the accumulator punter’s toolkit, and the brand positions itself that way. Licence: account 39170 (Netbet Enterprises Limited).

The verdict: built for the bettor who builds accas, and the Bet Builder’s instant dynamic odds are the feature that pays for itself when a leg is added live. For a single-bet value punter the boost stack is the wrong shape, because boosted odds tend to attach to the most popular markets, where the margin is already tight and the value is thinnest.

BetUK — a small-stakes welcome with exclusions worth reading

BetUK’s free bet terms exclude virtual sports, esports and non-UK/IE horse racing, and minimum odds apply to the qualifying bet. That is the kind of exclusion list a small-stakes punter can use and a casual reader should not skip: the qualifying bet has to be on a market the offer actually pays out on, and the minimum odds rule is the line between a qualifying and a non-qualifying bet. Licence: account 39198 (LeoVegas Gaming PLC).

The verdict: a workable free-bet entry for a punter who reads the small print. The exclusions are not unusual for the market, but they are the part of the page that decides whether the offer is real money or a marketing sticker.

bet365 — the benchmark menu with the breadth to cover any strategy

bet365’s published feature set is the closest thing to a benchmark the British market has: Bet Builder+ for same-event combinations pre-match and in-play, Super Boosts, Winnings Boosts on Bet Builders and selected singles, and daily Bet Boosts across the major sports. bet365 holds a remote general betting standard (real events) licence (account 55148, Hillside (UK Sports) ENC, the UK-facing arm of the bet365 group).

The verdict: the operator a value punter compares every other operator against. The menu is wide enough to handle any strategy, the in-play depth is the deepest on the list, and the Bet Builder+ is the most flexible version of the feature in the market. The market position is also the catch: the prices on the most popular markets at the most popular times are the most efficient in the market, and the value edge is on a less popular market or a less popular time.

Paddy Power — Super Sub and a builder built for football

Paddy Power’s published offering is the same Bet Builder+ idea as bet365, plus Super Sub (a bet rolls over to the replacement if a selected player is substituted), expanded Win More markets, and player and ACCA stats. Paddy Power holds a remote general betting standard (real events) licence (account 39439, PPB Counterparty Services Limited). Paddy Power and Betfair are run from the same Flutter group, which is the reason both appear on the Commission’s register under related but separate licences.

The verdict: a strong choice for the football-only punter, because Super Sub is the only feature on the list that turns a substituted player into a live position rather than a dead leg. For a value punter, the Win More and Super Sub enhancements are the things to track, and the rest of the menu is standard for a major book.

London Bet — a small menu, a UK licence, a niche focus

London Bet is published by Thistle Bet Limited and states it is licensed and regulated in the UK; the app has a 17+ age rating. The published feature set is the smallest on the list, and the brand’s positioning is a smaller, more local book than the major chains. The licence is a remote general betting standard (real events), account 66162, held by Thistle Bet Limited.

The verdict: a workable third or fourth book for the punter who already has a primary account at a major brand and wants a price comparison on a market the majors are thin on. The published feature set is the part of the comparison to read with care: the small brand is small because it under-covers, not because it under-prices.

888sport — racing streams and a daily boosted-odds line

888sport’s published feature set covers the standard bookmaker menu — pre-match and in-play betting, Cash Out, Bet Builder, racing streams, BetFinder form tools, a live bet feed and daily boosted odds. The licence is a remote general betting standard (real events), account 39028, held by 888 UK Limited.

The verdict: a workable secondary book, with the racing streams as the differentiator for the horse-racing punter. The BetFinder form tools are the feature the value bettor is most likely to under-use, because the closing line is set by the market and the form is set by the past, and the two are not the same thing.

Smarkets — a betting exchange, not a bookmaker

Smarkets is the only operator on the list that runs as a betting exchange under a remote betting intermediary licence, account 39173, held by Smarkets (Malta) Limited. The published terms are commission-based: a standard 2% on eligible exchange bets, with new customers having been offered 0% commission for 60 days on a minimum first deposit of £10. There is no margin in the prices the way a traditional bookmaker builds one; the commission is the operator’s cut on net winnings.

The verdict: the row on the list that does the most for a value punter. The exchange’s prices are the closest thing the market offers to true probabilities, and the commission model means the edge is paid for by the loser, not baked into every price. The catch is the market depth: the smaller liquidity on the exchange is the reason a £1,000 lay on a 1.50 shot can move the price, and a value punter with a small stake will not see the price move, while a value punter with a large stake will.

Octobet — Best Odds Guaranteed on UK and Irish racing

Octobet is the smallest brand on the list, with a published Best Odds Guaranteed concession on UK and Irish horse racing, up to £150 per customer per race. The licence is a remote general betting standard (real events), account 62545, held by Octopus Game Limited.

The verdict: a workable secondary book for the racing punter who already has a primary account with a major brand, and the £150-per-race cap is the part of the terms to read. The cap is high enough to make the BOG a real concession on most weekend handicaps, and tight enough to make a Festival-week stake worth checking against the cap before laying the bet.

Tote — pool betting and best odds guaranteed from 8 AM

Tote is the only pool-betting operator on the list and runs under a remote general betting standard (real events) licence, account 54779, held by TDCO Limited. The published BOG terms are different from a fixed-odds bookmaker: Best Odds Guaranteed is paid on UK and Irish horse racing from 8 AM on the day of the race, on single and multiple bets, and the concession does not apply to ante-post, tote or pari-mutuel bets. The pool structure — dividends paid from the pool of stakes rather than from a fixed-odds book — is what makes the Tote different in price terms from a traditional bookmaker.

The verdict: a separate kind of bet, not a substitute for one. The pool dividend on a winning horse is set by the pool of money on the race, and a value punter’s edge is in picking horses the pool is under-pricing — the same logic as a value bet on a fixed-odds book, with a different price-discovery mechanism. The 8 AM start time on the BOG concession is the part of the terms that decides whether the offer is real money or marketing.

Bonuses, free bets and the 10x cap

A bonus at a GB-licensed operator can require no more than 10 times the bonus in qualifying bets, in force since 19 January 2026. A £10 bonus at the cap means £100 of qualifying bets; the same bonus at 50x — the level several brands used to publish — is now outside the rules. The cap is on the wagering requirement, not on the size of the bonus itself, and the cap does not apply to a free bet with no wagering condition at all. The Commission’s separate ban on mixed-product promotions — an offer that asks the punter to bet on football to get free spins on a slot, for example — is the other half of the same reform: the offer has to live in one product, not be a cross-sell.

The arithmetic of a free bet whose stake is not paid back is simple. A £10 free bet at decimal odds of 4.00 wins £40, of which the stake is not returned; the net is £30. The free bet’s value to a punter is the edge on the market, not the gross return. A free bet used on a market with a 5% margin is worth less than the same free bet used on a market with a 2% margin, because the price on the second market is a fairer price, and the gap between the price and the punter’s probability is bigger.

A deposit-gated welcome package — a free bet on the first deposit, a second on the second — is not the same as a no-deposit free bet. The package usually carries a minimum deposit, a minimum odds rule on the qualifying bet, a deadline, and a cap on free-bet winnings. The cap on free-bet winnings is the part of the terms that turns a generous-looking offer into a real-money one: a £10 free bet with a £100 cap on winnings is worth less than a £10 free bet with no cap, because the upside is bounded. The audit of any welcome offer is the wagering requirement, the minimum odds, the deadline, the cap on winnings, and the list of excluded markets. Every one of those is in the operator’s own terms.

Advertising for bonuses runs through the CAP Code (non-broadcast) and BCAP Code (broadcast), enforced by the ASA, alongside the Commission’s LCCP marketing conditions. The rules say 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 appear in the advertisement in a gambling role, with an exception for marketing placed where a bet can be made directly. That is a rule about who can be shown in the advert, not about who can bet. The “whistle-to-whistle” rule — no betting ads on TV from five minutes before a live sporting event to five minutes after, before the 9pm watershed — is an industry code rather than statute, in force since 1 August 2019, with horse and greyhound racing excluded.

The mobile experience: in the app or in the browser

The bookmakers on this list publish iOS and Android apps alongside their mobile sites, and the comparison between the two is mostly a comparison of which the punter prefers. An app loads faster on a strong signal and is where push notifications — price drops, team news, bet settlement — are delivered; a mobile site is where the punter who does not want to install an app lays the bet. Both are GB-licensed and both are under the same licence and the same protection.

In-play depth is where the mobile comparison sharpens. A major book with the deepest in-play menu — bet365, Paddy Power — is the one whose app is built for a punter who wants to bet from the ground. A book with a thinner in-play menu — the smaller brands on the list — is built for a punter who wants to place a pre-match bet and then close the app. The punter’s strategy is the test of which shape suits.

The bettor who values a Bet Builder is the one who notices the difference between a builder that updates the price as legs are added (NetBet, bet365) and a builder that returns a single price at the end. The first is built for the punter who wants to know the price before committing; the second is built for the punter who wants to lock in a shape. Both are valid; both are within the Commission’s definition of a same-event combination bet.

Live betting and cash out

A live bet is one placed after the event has started, at a price the bookmaker updates in real time. The bookmaker’s margin on a live market is typically wider than on the equivalent pre-match market, because the price has to cover a less-certain outcome and the bookmaker’s risk management has to be quicker. A live bet on a football match at 1-0 is a different price from the same selection at 0-0, and the gap is set by the operator’s own traders, not by a published formula.

Cash out is the bookmaker’s offer to settle a bet before the event ends, at a price the bookmaker sets on the current state of play. The cash-out price is below the price the bet would clear at if it ran to the end, because the bookmaker’s margin is in the cash-out price as well as in the original bet. A punter who cashes out a winning bet is paying the bookmaker for the certainty of the settlement; a punter who lets a winning bet run is foregoing the cash-out margin in exchange for a bigger payout if the bet wins at the end. The trade-off is the punter’s, and the only general rule is that the cash-out margin is wider on a more uncertain event and tighter on a near-certain one.

In-play is regulated by the operator’s licence conditions and customer-protection duties, not by a separate statute. There is no published prohibition on in-play betting, and there is no published ceiling on stakes. The punter’s discipline is the ceiling: a stake the punter can afford to lose, on a market the punter has priced correctly, is the only test.

Predictions, strategy and the bankroll

A “prediction” in the betting sense is a probability estimate for an outcome. A value bet is a price that beats the estimate. A “tip” is a recommendation, sometimes with a price and sometimes without. A “system” is a rule the punter applies to every bet: a maximum stake, a minimum odds rule, a closing-line check, a stop-loss. None of those is a system that wins. A system that wins is a system that has found a mispriced market, and the mispricing closes as soon as the market notices, so a system that worked last season is a system that will need to be re-tested this season.

The Kelly criterion is the textbook tool for sizing a value bet. For a binary bet with a probability of winning *p*, a probability of losing *q* (1 − *p*), a fraction *g* gained on a win and a fraction *l* lost on a loss, the formula is *f* = p/l − q/g. With a 60% chance of winning at even money (p = 0.6, q = 0.4, g = l = 1), f = 0.6 − 0.4 = 0.2, so 20% of the bankroll is staked on each bet. That is a full-Kelly position, and most professional bettors use a fraction of Kelly — a half-Kelly or a quarter-Kelly — to dampen the variance of the bankroll. A full-Kelly punter is the punter who hits a bad run, and the bankroll halves before the bets come good.

The closing line value is the standard the betting literature uses to grade a punter’s eye. A bet at 4.00 that closes at 3.50 is a beat of the closing line, and a series of closing-line beats is the closest the punter can come to a proof of skill. A bet at 4.00 that closes at 4.50 is a miss, and a punter with more misses than beats over a sample size is a punter whose model is not yet sharp.

A bankroll is the money the punter has set aside to bet with, separate from the rent and the bills. The punter’s edge is small, the variance is high, and the bankroll is the buffer that lets the punter ride out a losing run. A bankroll of £500, a unit stake of £10 and a 5% target on bankroll per month is a workable small-stakes setup; a bankroll of £500, a unit stake of £50 and a 5% target is a setup that will run out of money in a bad month.

Bet types and the odds that price them

A single is a bet on one selection. A double is two selections, both of which must win. A treble is three. An accumulator (“acca”) is four or more. The odds multiply: a treble at 2.00, 3.00 and 4.00 has a combined price of 24.00, and a £5 treble returns £120. The bookmaker’s margin compounds across the legs, and an acca of six tight-priced legs carries a higher margin than any one of them on its own. A punter building an acca is paying a margin on every leg and a compounded margin on the whole bet.

A Lucky 15 is 15 bets on four selections: four singles, six doubles, four trebles and a four-fold accumulator, all at the same unit stake, so a £1 Lucky 15 costs £15 and pays out on any winning leg. A Trixie is 4 bets on three selections: three doubles and a treble. A Yankee is 11 bets on four selections: six doubles, four trebles and a four-fold. A Heinz is 57 bets on six selections, a Super Yankee / Canadian is 26 bets on five, and a Goliath is 247 bets on eight. The stake is the unit stake multiplied by the number of bets, and the punter’s edge on each leg is multiplied or compounded through the combination.

An each-way bet is two bets of equal stakes: a win bet and a place bet. The place terms depend on the race and the number of runners, and the place pay-out is a fraction of the win price. Each-way betting is the way to back a horse for a place rather than a win, and the place pay-out is the part of the bet that does the heavy lifting on long-odds horses. A Rule 4 deduction is a bookmaker’s rule applied when a horse is withdrawn from a race: the deduction is taken from the winnings on the other runners, and the size of the deduction is set by the bookmaker’s published table.

A bet builder is a same-event combination bet: a single price for a combination of selections on one match (a player to score, both teams to score, over 2.5 goals, for example). The same-event combination is the feature the operators on this list have published under various names — Bet Builder, Bet Builder+, same-game multi — and the prices are set by the operator’s own model. A bet builder is a compounded single bet, and the margin on the combined price is higher than the margin on any one of the legs.

A betting exchange is a market for bets between punters, with the exchange taking a commission on net winnings. A back bet is a bet on a selection to win; a lay bet is a bet on a selection to lose, and the lay price is the backer’s liability. A spread bet is a bet on a number — a horse’s finishing position, a footballer’s goal tally, a cricket team’s runs — and the pay-out is the size of the win multiplied by the difference between the spread and the outcome. Spread betting on a financial index is regulated by the Financial Conduct Authority, not the Commission, and the punter’s losses can exceed the deposit.

Sports, tournaments and the value edge

Football is the British punter’s biggest market and the operator’s most efficient one. The margin on a Premier League match is the tightest in the book, and the value edge is the thinnest. A punter looking for a football edge is looking for a market the bookmaker is not sharp on: a League Two match, a Conference fixture, a women’s football match, an in-play price on a substitution. The shape of the edge is in the part of the menu the major books under-cover.

Horse racing is the British punter’s other major market, and the value edge is on the form. The starting price is set by the market, the best odds guaranteed is the bookmaker’s promise to pay the higher of the price taken and the SP, and the form is set by the past runs. A punter with a model that prices a horse better than the market is a punter with a value edge; a punter who backs every favourite at SP is a punter who pays the bookmaker’s margin on every race.

Tennis is the in-play sport. The match is a series of points, the price updates with every point, and a punter who can read the form of a server is a punter with an edge on the next-game price. The in-play margin on tennis is tighter than the in-play margin on football, because the price-discovery mechanism is faster.

Cricket, golf, rugby and American football are the sports with longer event cycles. A Test match is five days, a golf tournament is four rounds, a rugby match is eighty minutes, an American football game is sixty minutes plus stoppages. The bookmaker’s model is less sharp on the long-cycle sports, and the value edge is correspondingly wider.

A closing line is the price on the market at the moment the book closes, whether that is the off in a horse race, the first ball in a cricket match, the kick-off in a football match or the start of play in a tennis set. The closing line is the standard the betting literature uses to grade a punter’s edge, and a punter who beats the closing line over a sample size is a punter who is, in the technical sense, finding value. The size of the sample size — typically a few hundred bets at least — is the part of the claim that the casual reader tends to skip.

The arithmetic of a 5% margin on a two-way market

The margin on a two-way market at decimal odds 1.90 / 1.90 — the kind of line a bookmaker might publish for a closely priced football fixture — is 1 minus the average of the two implied probabilities. Each side implies 1 ÷ 1.90 = 52.63%, summing to about 105.3%, and the margin is in the 5-point gap. A punter betting £10 on each side of this market at these prices would stake £20 and receive £19 back, a £1 loss to the bookmaker on every matched £20 of stakes. A 5% margin is a tight book for a major sport, and the band — typically 4% to 6% on a major fixture, 8% to 12% on a smaller one, more on an exotic market — is the level the punter should expect on a GB-licensed site.

A two-way market at 1.80 / 1.80 implies 55.6% on each side, summing to 111.1%, and the margin is 11.1% — twice as wide as the 1.90 example, and the price of a less efficient market. A two-way market at 1.95 / 1.95 implies 51.3% on each side, summing to 102.6%, and the margin is 2.5% — a price the major books publish on the most popular football fixtures, and the tightest the British market routinely offers. The band the punter is looking at, on a two-way market at a major book, runs from about 2.5% at the tightest to about 12% at the widest, with most of the menu between 4% and 8%. The margin is a snapshot of one event on one bookmaker’s site at one moment, and the punter’s reading of it is the punter’s edge.

Frequently asked questions

How is a value bet found?

A value bet is a price the bookmaker offers that is more generous than the punter’s own probability for the outcome. The punter forms a probability — by form, by stats, by a model, by a market move — and compares it to the price: if the price is bigger than the probability justifies, the bet is a value bet. The standard test is the closing line: a bet that beats the closing line over a sample of a few hundred bets is a bet whose edge is real, and a bet that misses the closing line is a bet whose model needs work.

What is value betting, in one sentence?

A value bet is a wager whose price exceeds the punter’s estimate of the true probability, so that over a series of such bets the punter’s expected return is greater than the stakes laid out.

What is a closing line value in betting?

The closing line is the price on the market at the moment the book closes — the off in a horse race, the kick-off in a football match, the first ball in a cricket match. A bet that beats the closing line is a bet whose price was better than the market’s final view of the event, and a series of closing-line beats is how the betting literature grades a punter’s eye.

How is a bookmaker’s licence checked on the public register?

The Gambling Commission’s public register is searchable by business name, trading name, domain or account number. The search returns the licence categories, the licence holder and the account status. A brand that does not appear on the register is not a GB-licensed operator, regardless of the marketing, and a GB-licensed operator that has been suspended or had conditions attached will show that on the register as well.

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

For a single at decimal odds *o* and a stake of *s*, the return is *s × o* and the net profit is *s × (o − 1)*. A combination bet multiplies the legs: a double at 3.00 and 4.00 is a single price of 12.00, and a £5 double returns £60 if both legs win. A free bet whose stake is not paid back returns *s × (o − 1)* on a win, because the stake is forfeit.

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

The bookmaker’s margin is the gap between the sum of the implied probabilities on every outcome of a market and 100%. On a two-way market at 1.90 / 1.90, each side implies 52.6%, the sum is 105.3%, and the margin is the 5.3-point excess. The lower the margin, the more of every pound the bookmaker pays back to winning punters, and the more efficient the market. The margin is a snapshot, not a permanent feature, and it changes by event, by market and by the time of day.
