A “tip” sounds like a name, a horse and a price. Behind the headline sits something slower: a way of reading form, a discipline for staking, a rule for telling whether the price on offer is fair once the bookmaker’s margin is taken out, and the choice of a bookmaker whose terms suit the kind of bet you actually want to place. This page is built around that distinction. Nothing here names a winner. What it does is unpack the mechanics that turn a tipster’s word into a number, the arithmetic that turns that number into a return, and the bookmaker features that change what a winning bet pays out.

Data current as of 26 October 2026 against the Gambling Commission’s public register for licence verification.

Reading form: the parts a tip is built from

A tip is the last link in a chain, not the first. The chain starts with form — past runs, conditions, the going — moves through pace and sectional reading, and ends with the price the market quotes. Anyone can call a winner; the work is in the chain.

Form is the visible record: finishing positions, beaten distances, the going (firm, good, soft, heavy), the trip (distance in furlongs or miles), the class of race and the type of course (flat or jumps, right-handed or left-handed, tight or galloping). Two reads sit on top of that raw form. Pace maps try to predict how the race will be run — whether it sets up for a front-runner, a hold-up horse, or one that travels well off a strong tempo. Sectionals and speed figures try to standardise performances across courses and conditions by adjusting for the pace of the race, the going and the track. Both rely on data the racing press publishes freely and that the racing analytics services sell by subscription.

Handicaps reshape the picture once more. In a handicap, each horse carries a weight set by the official handicapper, whose job is to give every horse a fair chance of winning. The draw matters more in big-field flat handicaps than in small-field stakes races; the going matters more in jumps than on the flat, because soft ground punishes horses that jump out of heavy ground and helps those that stay further. In a conditions race the weights are equal across the field, with allowances for age and sex; the picture is closer to a contest of form than to a contest of handicapping.

None of this guarantees a winner. What it does is narrow the field of plausible contenders and price the race accordingly. A horse whose form reads worse than its price implies is one to oppose, regardless of who tipped it; a horse whose form reads better than its price is one to back. That second move is the value bet, and the page returns to it.

The bet types that pay for a tip

The market offers more than a single bet on the favourite. Understanding the bet type is what turns a name on a card into a number the punter can pocket or collect. Horse racing carries its own vocabulary; most of it is settled by the same arithmetic as any other sport, but a few terms are specific.

Singles, doubles and accumulators

A single is one selection. Its return, at decimal odds, is the stake multiplied by the price. The profit — what the punter pockets on top of getting the stake back — is the stake multiplied by the price minus one. A double is two selections, both of which must win; the prices multiply into one combined price. A treble is three, and an accumulator or “acca” is any number from four upwards. The longer the chain, the larger the combined price — and the lower the chance of every leg landing. The bookmaker’s margin compounds with each leg, so a five-fold acca carries a wider overround than the same five races priced individually.

A combined bet on a single meeting is the equivalent of a bet builder on football: legs multiplied, settled as one ticket, the stake lost if any leg fails. Some bookmakers offer acca insurance, which refunds the stake as a free bet if one leg lets the rest down; the refund is in free bets, not cash, and the free bet’s own stake is usually not returned when it wins. That distinction is the difference between a £10 free bet on a 5/1 shot returning £50 and one returning £60. Always check which side of that line an offer sits on.

Each-way: two bets of equal stake

The each-way bet is the market’s signature bet on horse racing. It is not one bet — it is two, of equal stake, settled in parallel. One is a win bet on the horse to finish first. The other is a place bet on the horse to finish in a specified number of places. The stake is therefore doubled: a £5 each-way bet costs £10.

Place terms vary by race and by bookmaker. In a handicap with more than fifteen runners, the standard is one quarter of the win odds for the first four places. In a handicap with twelve to fifteen runners, one quarter for three places. In non-handicap races with more than seven runners, one fifth for three places. In races with five to seven runners, one quarter for two places. In fields of fewer than five runners, place betting usually does not run at all — the each-way bet collapses into a win-only bet. Bookmakers can offer more generous place terms than the standard; Ladbrokes, William Hill and bet365 routinely do on feature races. The terms are printed on the betting slip and on the race card.

A worked example, in pounds sterling. A £10 each-way bet on a 10/1 horse at one-quarter place terms for three places costs £20 in stake. If the horse wins, the win part pays £10 × 11.00 = £110 and the place part pays £10 × (10 ÷ 4 + 1) = £10 × 3.50 = £35, for £145 in total including the returned stake. If the horse finishes second or third, the win part loses and the place part pays £35. The point to remember: the stake doubles, the win part of the price does not change, and the place part of the price is one fraction of it, not the same number.

Forecasts, tricasts and other exotic bets

A straight forecast names the first two in order. A tricast names the first three in order. Combination forecasts cover every permutation of two from a stated set of horses; combination tricasts cover every permutation of three. Returns are paid from a dividend declared after the race, not at a fixed price — the dividend depends on how much is staked into the pool, so a forecast on a race with little money on it can pay handsomely and one on a hot favourite can pay poorly.

Spread betting on horse racing: a different species

A spread bet does not carry a price. It carries a spread — a range within which the market-maker thinks some measurable outcome will land. The bet is on where within the spread the result settles, and on how many units above or below the spread the result lies. Spreadex runs both fixed-odds betting under a Gambling Commission licence and financial spread betting under Financial Conduct Authority regulation; it states plainly that losses on spread bets can exceed the deposit. A £5-per-point bet on a winning distance spread that settles thirty points in the punter’s favour returns £150. The same bet on a result that settles against by twenty points costs £60. The arithmetic is symmetrical, but punter behaviour is not: the upside is bounded by the punter’s nerve and the downside by the size of the loss they are willing to wear. Spread betting is the kind of bet to read about before it is touched.

Ante-post and non-runner rules

Ante-post bets are placed before the final declarations, when a horse may yet be withdrawn. The price is bigger because the field is uncertain; if the horse does not run, ante-post stakes are usually lost. Bookmakers publish a non-runner rule that adjusts stakes or settles the bet differently when a horse is taken out after the final declaration. Rule 4 deductions reduce the price when a horse is withdrawn from a race close to the off, because the field has shortened and the bookmaker’s margin on the remaining runners has shifted. The deductions are standard across the industry: a Rule 4 of 25p in the pound on a withdrawn favourite, scaled down for less fancied horses. The terms are on each operator’s site.

The bookmaker’s margin: why every price carries a tax

A bookmaker is a market-maker, not a counterparty on a fair coin. The price on offer is not the price at which a knowledgeable punter would lay the same bet to a friend. The difference is the margin — sometimes called the overround — and it sits inside every quoted price, on every market, on every meeting.

On a two-way market with decimal odds of 1.90 against 1.90 — say, the favourite to win a two-horse match bet — the implied probability is one over 1.90 for each side, or about 52.6% on each side. Add them up: 105.3%. The two-and-a-bit percent above 100% is the margin. That is what the bookmaker keeps, on average, out of every pound staked into that market, before considering the outcomes.

The margin varies by market. A win market on a twelve-runner race typically carries a margin of 20% to 30% — the favourite pays 4/1, the longshots pay 200/1, and the cumulative implied probability runs well over 100%. A place market, where the bookmaker names the place terms and prices each horse against them, carries a tighter margin in the middle of the field. Forecast and tricast pools carry their own margin inside the dividend declaration.

What this means for a punter is straightforward. A 5% margin on a market means that the bookmaker keeps five pence of every pound staked into that market, on average, over a settled period. A 25% margin means twenty-five pence. Markets with thinner margins reward a sharper reading of form more directly, because the punter’s edge has less of the bookmaker’s edge to overcome.

The practical consequence: a tip is only a tip if the horse’s chance of winning, in the punter’s honest estimation, is bigger than the implied probability inside the price. The implied probability is one over the decimal price. A 5/1 shot has an implied probability of one over six, or about 16.7%. If the punter genuinely thinks the horse has a 25% chance, that is a value bet. If the punter thinks the horse has a 15% chance, it is a bet that loses in the long run regardless of who tipped it.

Top 10 UK horse racing bookmakers at a glance

The table below maps each operator’s Gambling Commission licence to what that operator’s own published terms state on the bookmakers’ key subjects — best odds guaranteed, each-way place terms, in-play racing and acca insurance. It is a comparison of stated terms, not a judgement of who pays out faster or who is nicer to deal with. Every brand below holds a remote licence on the Commission’s public register; the licence number is the single fact that settles who does and who does not.

Every operator in the table holds a remote general betting standard (real events) licence on the Commission’s public register. Every one takes part in GAMSTOP. The licence is the floor of the comparison; the columns above describe what each operator offers on top.

Tote — pool betting at the heart of the market

Tote runs pool betting on UK and Irish racing. A pool bet is not a bet at a fixed price — the stake goes into a pool, the pool is divided after the race by a takeout, and the dividend is declared once the result is known. The advantage is that there is no bookmaker’s margin in the traditional sense: the takeout replaces it, and the punter’s edge or disadvantage is the difference between the pool dividend and the true odds. The disadvantage is that the dividend on a heavily backed favourite is poor, and the dividend on a longshot with little money behind it is handsome.

Bar One Racing — an Irish shop bookmaker with a digital arm

Bar One Racing is an Irish independent with shops across Ireland and sponsorships at Dundalk, Fairyhouse, Navan, The Curragh, Curraheen Park and Cork. The digital offering carries the same racing-heavy book as the shops, with each-way terms and Best Odds Guaranteed available on UK and Irish racing.

Fitzdares — a premium racing-led bookmaker

Fitzdares’ app carries cash out, accumulators, Lucky 15s, specials and ante-post markets on horse racing, football, tennis, rugby, cricket, golf and American football, with in-play live odds. The racing product is the centre of the offer; the other sports sit alongside.

bet365 — in-play and live streaming

bet365’s app offers in-play betting and live streaming of events worldwide, plus Bet Track, Match Live and a Live Golf Tracker for following bets in play. The racing product covers UK, Irish and international meetings, with Best Odds Guaranteed on the day and live streams on the major festivals.

Dabble — a peer-betting hybrid

Dabble runs a sportsbook and a casino. The welcome offer terms are a £10 stake for £10 in free bets on a first deposit, with a 7-day free bet expiry, minimum odds and the free bet stake not returned. The platform also lets punters follow and copy other users’ bets — a social layer that sits on top of the fixed-odds book.

BetMGM — a sports welcome tied to multiples

BetMGM’s UK sports welcome offer pays four £10 free bets — two on football accumulators of four or more selections and two on sports multiples of two or more — for new customers who deposit £10 and place a sports bet within seven days. Opt-in is required, the free bets expire in seven days, and minimum odds apply. The structure rewards multi-leg bets over singles.

BoyleSports — acca insurance and Irish roots

BoyleSports runs an acca insurance offer: a £5 minimum stake, 1/2 minimum odds, a £20 maximum refund as a free bet that expires in seven days, with the bet to be placed and settled on the same day. Opt-in is required. The racing product runs Best Odds Guaranteed on UK and Irish racing and a deep each-way place book.

Ladbrokes — a high-street bookmaker with a deep racing product

Ladbrokes runs odds boosts on horse and greyhound bets, Best Odds Guaranteed on UK and Irish racing, in-play betting and Acca Boosts. The betting exchange and the sportsbook sit under one licence holder, LC International Limited, which also runs the Coral brand.

Fafabet — BOG from 9am on race days

Fafabet pays Best Odds Guaranteed on UK and Irish horse racing win and each-way bets from 9am on race days: if the starting price (SP) is bigger than the original price taken, the bigger odds are paid. The BOG time differs across operators — William Hill pays from 8am — and the difference matters when an early price is taken the night before.

Fitzwilliam Sports — phone-first with chat

Fitzwilliam Sports offers phone and live chat with the office open 09:00 to 21:00, Monday to Sunday, and messenger replies generally within 90 seconds. The model is closer to a traditional bookmaker than an app-first sportsbook: the customer rings in, gets a price and places a bet.

The landscape: who each kind of punter suits

A bookmaker is not the same as another. The differences are in the price you pay, the rules around your bet and the kind of customer support you get when something goes wrong. Choosing one is a question of what you want from the bet.

The traditional shop bookmakers — Ladbrokes, William Hill — run a deep racing product with Best Odds Guaranteed, generous each-way place terms on feature races, and a stack of racing-led promotions. They suit the punter who bets mainly on UK and Irish racing, takes early prices the night before, and wants the bigger SP paid if the horse drifts.

The pure-digital sportsbooks — bet365, BetMGM, Fitzdares — run a broader product with live streaming, in-play and bet builders. They suit the punter who mixes racing with football, tennis and American sports, and who wants to watch the race while betting in-running.

The Irish independent bookmakers — Bar One Racing, BoyleSports — carry an Irish racing-heavy book with a strong each-way and place market, and acca insurance for the multi-leg punter. They suit the punter who bets on Irish meetings, follows the smaller tracks and prefers a place-led book.

The phone bookmaker — Fitzwilliam Sports — suits the punter who wants to talk to a human, gets a price and is comfortable with a smaller sportsbook than the giants offer.

The pool operator — Tote — suits the punter who prefers a dividend to a fixed price, and who understands that pool betting rewards the longshot that paid well over the favourite that paid little.

Statute and licence: the legal frame

A bookmaker serving customers in Great Britain needs a Gambling Commission licence wherever it is based. The Commission is a non-departmental public body sponsored by the Department for Culture, Media and Sport, and it licenses the whole commercial market under the Gambling Act 2005. Northern Ireland is outside the Act and runs on its own older law. The Commission’s public register is searchable by business name, trading name, domain or licence number, and the register is the whole test of whether a brand holds a licence.

Since the Gambling (Licensing and Advertising) Act 2014, an operator whose remote facilities are used in Great Britain needs a Commission licence even if its offices and servers sit in another jurisdiction. A Curaçao, Maltese or Gibraltar licence is not a substitute. The licence categories relevant to a horse racing punter are remote general betting standard (real events) — which covers fixed-odds racing — and remote pool betting — which covers Tote-style pool products. A separate remote betting intermediary licence covers betting exchanges. Financial spread betting sits under the Financial Conduct Authority, not the Commission, and Spreadex is one of the operators that runs both licences in parallel.

The minimum age is 18, and name, address and date of birth are verified before a customer can deposit or gamble — including with a free bet or bonus. There is no anonymous play at a licensed site. The credit card ban for gambling in Great Britain has been in force since 14 April 2020, covering credit-card-funded payments through an e-wallet; debit cards and bank-based payments are not covered by the ban.

The general position: a GB licence is the floor. Every operator in the comparison table holds one. Some operators run under a single licence holder that also runs another brand — LC International Limited runs both Ladbrokes and Coral — and that matters when reading the small print.

Protecting the punter: what a licence buys

A licence is not a marketing slogan. It carries rules that change how a punter is treated.

GAMSTOP is the national multi-operator online self-exclusion scheme, and a mandatory licence condition for online operators since 31 March 2020. A punter who registers with GAMSTOP is excluded from every licensed online operator for 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 punter asks GAMSTOP to remove it. GAMSTOP covers online sites and apps; betting shops use a separate service.

A financial vulnerability check has been in force since 30 August 2024 (LCCP condition 3.4.4), applied 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, on bankruptcy or county court judgments — not an income check and not a credit reference check. The financial risk assessments that the press sometimes refers to as “affordability checks” have been announced in a staged plan, with no start date. The phrasing “announced, staged, no start date” describes them accurately; “in force” does not.

Operators must offer a gross deposit limit on a fixed time frame under RTS 12, with the first changes applied since 31 October 2025 and a second phase 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, and limits are the customer’s choice. Help is available through GamCare, which runs the National Gambling Helpline, GambleAware, NHS gambling clinics and Gamblers Anonymous.

A betting punter pays no tax on winnings in Great Britain. That is 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; the current rate is 15%, with a new remote betting rate of 25% applying from 1 April 2027 within it, while remote bets on UK horse racing, bets on self-self-service betting terminals in licensed premises, pool betting and in-person betting stay at 15%. Whether operators pass duty on through odds is not established; never write that the player is charged duty.

Crypto and anonymity at the betting counter

A GB-licensed operator verifies the customer’s name, address and date of birth before the first deposit. There is no anonymous play at a licensed site, and there is no licensed operator that accepts cryptocurrency as a deposit method — the customer is identified in pounds sterling through a UK-regulated payment route. Operators are not obliged to publish their payment methods, but the public profile of every GB-licensed operator is built around the pound.

Some unlicensed operators accept cryptocurrency and do not verify identity. They are not licensed under the Gambling Act 2005 and do not take part in GAMSTOP. The customer gets no Commission complaints route, no approved dispute-resolution body and no British consumer redress if funds are withheld. The customer is not bound by the 10x bonus cap or by the £150 vulnerability check. The bonus cap is a rule under licence conditions and the vulnerability check is a rule under the same — neither applies where the operator does not hold a licence. The wider trade-off is between a licensed bookmaker with checks, limits, GAMSTOP coverage and a bonus cap, and an unlicensed bookmaker with none of those protections and the risk of losing funds.

A bookmaker that claims to be “anonymous” or “no KYC” is making a marketing claim. The Commission’s enforcement record on operators serving GB customers without a licence includes cease-and-desist notices, search-engine referrals, work with registrars, hosts and payment providers, and powers — granted or in the process of being granted — to obtain court orders for DNS blocking. Honest framing: licensed = checks, limits, GAMSTOP, bonus cap, and the rule that you lose the stake if you don’t verify; unlicensed = none of those protections, possible loss of funds, and the prospect of the site itself disappearing.

Bonuses and free bets: the marketing word and the arithmetic

A free bet is the most common bonus on a UK racing bookmaker. The marketing word carries the headline — “£30 in free bets”, “bet £10, get £30” — and the small print carries the conditions. The arithmetic below the marketing word is what changes the picture.

A free bet whose stake is not returned is worth less than its face value. On a 5/1 shot at decimal odds 6.00, a £10 free bet pays £60 if it wins. The stake is not returned, so the punter pockets £60, not £70. The free bet’s actual value is £10 × (6.00 − 1) ÷ 6.00 × (the market’s payout share). On a market with a 95% payout share — a 5% margin — that works out to £10 × 5 ÷ 6 × 0.95, or about £7.92. The free bet pays £60 if it wins; on average, accounting for the chance of winning, it pays £7.92 per £10 of face value. That number is what the free bet is worth, not £10.

The promotion rules in force since 19 January 2026 cap wagering requirements on bonuses at 10x. A £10 bonus at 50x required turnover — the kind of bonus the cap was aimed at — would need £500 of qualifying bets; under the cap, the bonus is capped at £100 in face value and the wagering requirement at 10x. Mixed-product promotions — an offer that requires gambling on two or more product types, such as “bet on football to get free spins” — are banned. Whether the 10x cap applies to free bets with no wagering condition is not established, and any cap on the money value of a bonus is not established. What is established is the cap on wagering and the ban on cross-product offers.

A welcome offer’s headline rarely tells the punter what the offer costs. The terms list the minimum deposit, the minimum odds for the qualifying bet, the minimum odds for the free bet, the expiry of the free bet, the markets on which the free bet is valid, and whether the stake is returned with a win. The punter who reads those five things before claiming understands the offer; the punter who reads only the headline is taking the marketing word on trust.

The mobile and app landscape

A racing punter in 2026 bets on a phone more often than on a desktop. Every operator in the comparison table runs an iOS app on the UK App Store, and most run an Android client as well. The differences are in the live streaming, the in-play latency and the betting slip.

bet365’s app is the strongest of the racing-and-live-streaming combination: live streams of UK, Irish and international meetings, in-play odds on the same screen as the stream, and a bet slip that settles a cash-out request in a fraction of a second. Fitzdares’ app carries a deeper racing book, with ante-post and specials sitting alongside the daily card. Ladbrokes’ app is the broad high-street offering, with each-way terms and BOG on UK and Irish racing and an Acca Boost for the multi-leg punter.

The mobile experience is also where GAMSTOP’s coverage shows up. A punter who has registered with GAMSTOP is excluded from every GB-licensed app; the screen returns an exclusion notice at login, and the app does not accept deposits or place bets while the exclusion is active. That is the rule the app enforces, and it is the same rule on every licensed app.

In-play, live shows and cash out

In-play betting on horse racing is unusual in the GB market. Most racing in-running prices are suspended from the start of the race until the result, because the result settles too fast for the in-play market to clear. The exceptions are on long-distance races with a clear section-by-section read, and on selected bookmakers’ in-house feeds.

What GB racing punters get in-play is racing live streams. bet365 streams UK, Irish and international meetings live, with the race card and form alongside. Fitzdares streams a racing-led selection. Ladbrokes streams the feature meetings. The combination of stream and live odds on adjacent sports — greyhounds during the gaps, football in between meetings — is what most racing punters mean by “in-play”.

Cash out is a separate feature: it lets the punter lock in a return before the race settles. The return offered is the bookmaker’s mid-market price at that moment, and it carries the bookmaker’s margin in the same way any other price does. A cash-out at decimal odds 1.50 on a horse that opened at 3.00 is the punter taking half of the original price — the bookmaker keeps the other half as its cut of the cash-out. Cash-out is offered on singles and on accumulators; the acca cash-out is the more useful of the two, because locking in a five-fold at decimal odds 50 before the last leg is run lets the punter take a return without waiting for the final result.

The live show — a presenter-led broadcast on YouTube, Twitch or the bookmaker’s own channel — is a separate layer. Racing UK’s and ITV’s terrestrial coverage is the broadcast base; the bookmakers’ channels add presenter chat and price movement as the card unfolds.

Building a tip from the data: the strategy layer

The arithmetic of a tip is the part that survives the marketing words and the in-running noise. Three steps cover the practical work.

The first is the form read. Take the field, narrow it to horses whose recent form reads plausibly for the conditions, and discount the longshots whose recent form does not. The output is a shortlist of three to five horses, ranked by the punter’s honest read of their chance.

The second is the price read. Convert each horse’s price to implied probability — one over the decimal price — and compare it with the punter’s honest probability. The horses whose price implies a lower probability than the punter’s read are the value bets; the horses whose price implies a higher probability are the bets to lay or to skip.

The third is the stake. The stake follows the edge. A flat stake of one unit on every value bet — Kelly criterion or fractional Kelly — keeps the punter’s bankroll intact across losing runs. The punter who doubles the stake after a loss is chasing; the punter who halves the stake after a win is leaving value on the table. Bankroll discipline is what carries the strategy through to the long term, and the strategy does not survive without it.

No strategy wins in the long run against the bookmaker’s margin unless the strategy has a positive edge after the margin. A flat-stake strategy on a market with a 5% margin loses 5% of stakes on average; a value strategy that finds a 7% edge over the market’s implied probabilities nets about 2% of stakes over the long run. The size of the edge is the difference between a betting hobby and a betting cost.

The reading habit: how the data is verified

Every licence number on the comparison table sits on the Commission’s public register, searchable by business name, trading name, domain or account number. The register is the test of who holds a licence; the number is the fact. Every offer and every terms point in the table sits on the operator’s own site, the App Store description or the operator’s help pages. Both sets of facts are reproducible by the punter, and both can change: an operator’s licence can be varied or revoked, and an operator’s terms can be amended by the operator with notice. The punter who checks before they bet is the punter who is not surprised by what the small print says.

What this page does not do

No concrete picks, no predicted results, no sure bets and no system that wins. The market is set against the punter by the bookmaker’s margin, and no tip can overcome the margin on its own. A tip can sit on top of the punter’s reading of form, on top of the punter’s read of the price, and on top of the punter’s bankroll discipline. The tip without those three is a name on a card and a price in a window. The tip with those three is a wager placed at a price the punter understands.

Frequently asked questions

How do I bet on horse racing?

Pick a licensed bookmaker, fund the account in pounds sterling through a debit card or bank transfer, open the racing tab, find the meeting and the race, and add the selection to the betting slip. Choose the bet type — win, each-way, forecast, accumulator — and the stake, then confirm. The bet is settled when the result is declared; winnings are paid back to the account balance.

How do I work out a horse racing bet?

For a win single, multiply the stake by the decimal odds to get the return; subtract the stake to get the profit. For an each-way bet, the stake is doubled and settled in two parts. For an accumulator, the prices of all legs multiply into one combined price. For a forecast or tricast, the dividend is declared after the race and depends on the pool.

How do betting odds work in horse racing?

Odds are prices. Decimal odds of 6.00 mean a £10 stake returns £60; fractional odds of 5/1 mean the same. The implied probability is one over the decimal price. A 5/1 shot has an implied probability of about 16.7%. The bookmaker’s margin sits inside the cumulative implied probabilities of every runner; the margin is what the bookmaker keeps on average.

What is a value bet and why is no tip ever certain?

A value bet is a price that is bigger than the punter’s honest read of the horse’s chance. If the punter genuinely thinks the horse has a 25% chance and the price implies a 16.7% chance, the bet has a value edge. No tip is ever certain because horse racing is a high-variance sport with dozens of runners, variable going and pace — the horse with the best form can still finish fifth on the wrong pace. A tip’s job is to find the price edge; certainty is not on offer.

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

The overround is the cumulative implied probability across all runners minus 100%. On a market with decimal odds of 1.90 and 1.90 on a two-way match, the cumulative implied probability is about 105.3%, the overround is about 5.3%, and the margin is about 5.0%. On a twelve-runner win market, the overround is typically 20% to 30% and the margin is tighter. The margin is what the bookmaker keeps, on average, out of every pound staked into that market.

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

Return = stake × decimal odds. Profit = stake × (decimal odds − 1). For an each-way bet, the return is the sum of the win return (if it wins) and the place return (if it places) less the doubled stake. For an accumulator, the return is the stake multiplied by the product of every leg’s decimal price. Both subtractions and products follow the same arithmetic as a single bet.
