A punter standing at a counter with a pen and a blank betting slip is doing one of two things. They are adding legs to an accumulator, ticking a price, waiting for the kick-off — or they are wondering, after seeing a friend walk away with a wad of twenties, what the long-shot ticket on the counter actually pays when five legs all come in. The first question is about which bookmaker to use. The second is about the bet itself. Both are answered here, and they are answered in the order a reader needs them: the mechanism first, because the marketing photographs never explain it, and then the licensed sites, because that is where the comparison starts paying the rent.

The accumulators that turn up on coupon pages, acca boosts and “acca insurance” promos are not a separate product class. They are a way of staking on multiple selections at once, multiplying the prices together and taking a single return — or losing the lot on one losing leg. Every term in this guide (the full cover bets, the acca insurance, the bet builder, the cash out, the bet credits and the free bets that attach to them) is read against that single rule. A punter who knows it never reads the marketing the same way again.

How a bookmaker builds the price on an accumulator

An accumulator is a single bet that links two or more selections. All must win, or the bet loses. A leg that pushes — a horse dead-heats in a place market, the over/under lands exactly on the line — is removed and the odds contract to match what is left.

That is the whole of the structure. Everything else on this page is variation around it: the multiplication of the odds, the ways a bookmaker pays out early, the promotions that dress the ticket up, and the conditions that cancel those same promotions on a free bet.

The multiplication that turns three legs into a small fortune — or a stake lost

The return on an acca is the product of the odds of each leg, multiplied by the stake. Decimal odds make this trivial: 1.50 × 2.00 × 2.50 × £10 = £75 (a 5.00/1 in old money, the stake returned as part of the £75). In fractional form, the same three at 1/2, evens and 6/4 read 1.50, 2.00 and 2.50, and the arithmetic is identical. For an unrelated punter who has met fractional prices all their life, “decimal odds” was never a foreign concept — it is just the conversion done before the multiplication.

Here is the worked example with the inputs the page is built around: selections at 1/2 (1.50), evens (2.00) and 6/4 (2.50), a stake of £10 on an accumulator.

• The combined price is 1.50 × 2.00 × 2.50 = 7.50.
• The gross return at the same stake is £10 × 7.50 = £75.
• Net profit, after the £10 stake comes back inside the £75, is £65.

Three short-priced favourites that are each money down to the bookmaker and a single decimal of product give a stake its biggest lift. At £2 a line on a full-cover bet such as a Trixie (which uses the same three selections across four bets) the total stake is £8, and the biggest-pay line is the four-fold accumulator itself, which pays £15. Where a 4-fold or higher is one of several lines on the slip, the table on the slip is already doing the work — but the punter should still know what each line pays before the bet is struck.

Two riders belong next to that number. First, a leg that pushes removes that leg from the equation rather than voiding the whole bet — a 5-fold with one push becomes a 4-fold on the same terms. Second, an accumulator with one leg at very short odds and one at long odds is not “safer” than an accumulator of three middling selections. The multiplication treats every price the same way; the dominant risk lives with the leg the punter knows least about, not with the leg the bookmaker has priced shortest.

> At -110 moneyline odds a $110 stake returns $210 including the stake.

Why the bookmaker’s price always sits a little below the “true” odds

The leg prices the punter sees on the slip are not the probabilities an economist would write down. A bookmaker sets each market so that the implied probabilities of the outcomes sum to more than 100 per cent — the excess is the overround, also called the margin, and it is the bookmaker’s edge on every unit staked on the market.

The relationship is mechanical: with three outcomes priced as 1.30, 4.50 and 9.00 (decimal), the implied probabilities are 1/1.30 + 1/4.50 + 1/9.00 = 0.769 + 0.222 + 0.111 = 1.103, so the overround is 10.3 per cent and the payout share to customers is 1/1.103 = 90.7 per cent. The bookmaker keeps about 9.3 per cent on turnover, before any betting duty or operating cost. Lower overround means fairer prices; higher overround means the bookmaker’s cut is fatter.

For an accumulator the margin compounds with each leg. Three legs at a 6 per cent overround each give a combined overround of roughly 19 per cent, even before the operator’s choice of which markets to offer is itself a margin lever. The punter never sees the overround on the slip, but it is on every line of the ticket. The reader who wants to check it should divide each leg’s price into 1, add them up, and compare to 1 — the gap is the margin.

“Acca freeze”, cash out and edits after the kick-off

Modern bookmakers offer three products that live on top of an open accumulator: the cash-out, the acca edit (where supported) and the freeze feature that stops further cash-out changes after the punter has accepted the price offered.

Cash out pays the bet off before the final leg has run, at a price the bookmaker quotes from its current model of the remaining events. The punter is selling the ticket back at a discount to its present value — the discount is the bookmaker’s fee for ending the bet early, and it widens as the bet gets closer to settlement. Accepting a cash out is not a way of locking in profit; it is a way of swapping a possible larger return for a smaller certain one.

Acca edit lets a punter substitute one or more legs of an open accumulator — an injured striker pulls out, a horse is withdrawn — for a different selection on the same event or market. The edited bet is settled as a fresh accumulator with the same stake, and the price of the new legs replaces the old. Whether a bookmaker offers it on free bets is a separate question, taken up in the bonus section of this page.

Freeze is the position a punter holds in cash out: once they have accepted the price they have stopped the live quote, so the next price does not roll over theirs. Most operators freeze automatically, but a punter should not assume it; it is in the operator’s terms.

Full cover bets — many lines, one set of selections

The full cover bets are acca-shaped packages that share a set of selections across every sensible combination. The point of them is to cover a wider range of outcomes while keeping the leg prices that an acca punter wanted in the first place. They are not an alternative to the accumulator; they are the multiple-line version of the same selections.

• Trixie — 3 selections across 4 bets (3 doubles and 1 treble).
• Patent — same 3 selections across 7 bets (3 singles, 3 doubles and 1 treble).
• Yankee — 4 selections across 11 bets (6 doubles, 4 trebles and 1 four-fold).
• Lucky 15 — 4 selections across 15 bets (4 singles, 6 doubles, 4 trebles and 1 four-fold).
• Canadian — 5 selections across 26 bets.
• Heinz — 6 selections across 57 bets.
• Super Heinz — 7 selections across 120 bets.
• Goliath — 8 selections across 247 bets.

> A Heinz covers 6 selections in 57 bets and a Super Heinz covers 7 selections in 120 bets.

The total stake on a full cover bet is the unit stake multiplied by the number of bets. A Lucky 15 at £1 a line costs £15; a Goliath at 50p a line costs £123.50. This is the cost a punter must know before claiming a “free bet” on such a structure, where the bookmaker refunds one leg as a free bet rather than settling the whole coupon.

The full cover bets are settled as independent lines, and a push on one leg removes that leg from every line that uses it; the others stand. This is closer to the punter’s view of “what does each line actually need” than the accumulator is, and it is the structure where acca insurance (one leg down, free bet back) is most often written.

The legal frame in Great Britain

An accumulator is a bet on sports outcomes offered by a bookmaker licensed to take it. The Gambling Commission is the regulator, the Gambling Act 2005 is the statute, and the Commission’s public register is the test of who is licensed. In Great Britain there is no list of permitted bets — an operator holds a category of licence and offers markets under its own house rules and the LCCP.

The licence test, and what it means in practice

Every bookmaker serving customers in Great Britain needs a Gambling Commission operating licence, whatever its home jurisdiction. A Curaçao, Malta or Gibraltar base is irrelevant: the point-of-consumption rule has applied since the Gambling (Licensing and Advertising) Act 2014. There is no state monopoly and no cap on the number of licences.

The register is searchable by business name, trading name, domain and account number, and every brand on this page is on it as a remote general betting standard (real events) licensee. A licence is not a recommendation. It is permission to operate under the Commission’s licence conditions, and a listing on this page is “registered to do this”, not “good at this”.

Identity checks and the credit-card ban

Customers at a licensed site verify their name, address and date of birth before their first deposit, since 7 May 2019. Credit cards are banned for gambling in Great Britain, including credit-card-funded payments through an e-wallet. Debit cards and bank-based payments are not covered by that ban. The implication for a punter is that “sign up and bet in 60 seconds” is not a realistic expectation at a licensed site; the verification step is part of the licence, and an unlicensed site that skips it is one whose customer protections do not exist.

Bonuses, advertising and the 10x cap

Wagering requirements on bonuses are capped at 10x since 19 January 2026. A £10 bonus at 50x needed £500 of qualifying turnover; under the cap, no bonus carries more than £100 of required bets per £10 of bonus. Mixed-product promotions — an offer that requires gambling on two or more product types such as betting, casino, bingo and lottery — are banned. The 10x cap does not bind a free bet with no wagering condition, and there is no statutory cap on the money value of a bonus at the time of writing.

Advertising falls under the CAP Code (non-broadcast) and BCAP Code (broadcast), enforced by the ASA, alongside the LCCP marketing conditions. 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 the carve-out for marketing placed where a bet can be made directly). This rule is about who appears in an advertisement; the betting age is 18. None of this is a code a punter consents to; it is the framework the licensed operator operates inside.

Tax and what it means for the punter

The player pays no tax on betting winnings in Great Britain — this is general information, not tax advice, and a professional gambler is a different category to ask HMRC or an adviser about. General Betting Duty is the operator’s tax on gross profits; it is 15 per cent under current rules and from 1 April 2027 a new 25 per cent rate applies to remote betting, with UK horse racing, pool betting and in-person betting staying at 15 per cent. Whether operators pass duty on through odds is not established and a punter should not assume they do.

Offshore, and the loss of protection

Offshore betting has its own price, even when the price on the slip looks the same. A customer of an unlicensed site in Great Britain does not have GAMSTOP coverage, the Commission’s complaints route, an approved dispute-resolution body, or British consumer redress if funds are withheld. The 10x bonus cap, the £150 vulnerability check and the other player-protection rules do not apply. The Commission treats this as a matter of consumer protection and runs enforcement through disruption — cease-and-desist notices, work with registrars, hosts and payment providers — rather than blocking. Using an unlicensed site is “legal to access” in the loose sense a customer uses the word; the legal frame around it is the absence of the British protections just listed, and the punter carries that absence.

Where the ten licensed operators sit

The brands below are licensed for remote general betting (real events) on the Commission’s public register. The table is built around the four matters that decide an accumulator comparison: who holds the licence, on what account number, what the licence is for, and what each operator’s own terms say about the bet class in question. The pages that follow the table carry the detail behind each row.

The licensed acca bookmakers in Great Britain

A note on the column labels. The licence-holder column carries the company that is on the register against the trading brand; in several cases (BetUK and Betfred especially) the licensed company is the parent, and the trader sits underneath that parent as a brand. The page does not flatten these — the trader is the entity the punter sees and the licence holder is the one the Commission regulates, and they are written on the page as the register names them. The fourth column is a snapshot of what each operator’s own terms say about accumulators and the structures around them, not a list of every market offered. The terms page is the only place those are written out in full; the column is the cue, not the contract.

bet365 — the in-play heavyweight with a stacked acca product

Bet365’s accumulator offering sets the bar the rest of the market is measured against. The pre-match and in-play Bet Builder product is a same-game multi for one event; Super Boosts and the Winnings Boosts on Bet Builders and selected singles are additional price-promo products the operator runs on a fixture-by-fixture basis, not structural features. Cash out, partial cash out and auto cash out are present across the offer. Punters looking for the deepest in-play book on Premier League, Champions League and the top European leagues treat bet365 as the default; punters looking for a niche sport do not, because the depth is at the top of the football pyramid.

Hillside (UK Sports) ENC is the registered licence holder, remote general betting standard (real events), account 55148 on the Commission’s register. The verification flow is the standard Commission one — name, address, date of birth — and the operator runs GAMSTOP exclusion through the same flow as every other licensed remote bookmaker. For the punter, the verdict here is straightforward: where bet365 is strong, nothing in this comparison catches it, and the gap is most obvious on in-play on the Premier League. Where bet365 is shallow — niche sports, smaller leagues, niche markets — the comparison below still catches up.

Geoff Banks — ante-post and live prices, a smaller book

Geoff Banks is a smaller bookmaker focused on horse racing and greyhound racing, with ante-post prices on future events and an in-play book on the same fixtures as the day’s racing. The acca offering is more limited than bet365’s; the operator’s identity is the depth it covers on the racing side, where its app and site carry long-form ante-post and form data the bigger books compress. Multi-sport accumulators are not the focus, and a punter looking to load five football legs in one tap will not find their book here.

GB Sports Advisors Limited is the operator, licenced by the Commission for remote general betting (real events), and the trading brand sits underneath. The verification flow is the standard one, and GAMSTOP is honoured. Verdict for the punter: Geoff Banks is the right shop for racing-led accumulators — singles and multiples on the day’s racing — and the wrong one for a Premier League acca or a Champions League multi.

Kwiff — surprise boosts on the long-odds legs

Kwiff’s Supercharge feature is its identity in the acca comparison. The operator can boost the odds on a bet from a starting price to a much higher one — the operator’s own example is 2/1 to 20/1 — and the boost can apply to a multi-bet on any sport. The feature is the marketing image of the brand and it is also the line on which Kwiff is judged, because the boosts are not always there and the price the punter sees is the price after the boost, with the same composition rules as everyone else.

Spryme Ltd is the trademark operator and Eaton Gate Gaming Limited is the Commission’s licensed entity. The licence is a remote general betting standard (real events) licence, and the app has a 17+ age rating on the Apple App Store. Verdict: Kwiff is for the punter who wants a surprise on a long-odds accumulator leg. The standard price book is the operator’s regular one with Supercharge layered on top, and where Supercharge is on the leg the punter wants, no one in this comparison matches it.

Fitzwilliam Sports — Oddschecker-priced lines and a long-form book

Fitzwilliam Sports prices its selections against Oddschecker’s average price for the same selection at the time of bet placement. The implication for a punter comparing prices line by line is that Fitzwilliam is rarely the longest and rarely the shortest on the market — it is the average, plus or minus what an Oddschecker pull happens to hold at the moment the bet is struck. The bookmaker offers an iOS and Android app alongside the site, and the accumulators sit on the same slip as the singles.

SBKI Limited operates the site under a Gambling Commission licence for remote general betting. The verification flow is the standard Commission one. Verdict: Fitzwilliam is for the punter who has read Oddschecker and seen that the price on a selection is identical or close across the book, and who values that consistency as much as they value a sharp price somewhere else. It is the average book, and on accumulators it does what accumulators do at the average market price — nothing more, nothing less.

Dabble — social betting with a GAMSTOP-friendly onboarding flow

Dabble operates a social betting model, which is its identity: customers can follow tipsters, copy bets into their own slip and load accumulators in the same way other books do. The onboarding carries the same identity verification as every licensed bookmaker under the Commission’s rules, and a punter who is excluded through GAMSTOP will not pass that check on Dabble any more than they would elsewhere.

Dabble Sports UK Ltd is the licensed entity, holding a remote general betting standard (real events) licence. Verdict: Dabble is the right book for a punter who treats accumulators as a social event rather than a solitary one. The price book is operator-specific, the social features are unique to this operator in this comparison, and the licence terms are the Commission’s standard ones.

Swifty Sports — BOG and a Bet Builder still arriving

Swifty Sports sits on a tighter feature set than the bigger books in this comparison. Best Odds Guaranteed on UK and Irish racing, cash out on horse racing and football markets, daily price boosts and live streaming are present and verified; Bet Builder is listed by the operator as coming soon. For the punter loading a horse racing accumulator with BOG on every leg, Swifty does what an accumulator needs; for a punter loading a same-game multi on the Premier League tonight, it does not, until the Bet Builder lands.

Swifty Global (UK) Ltd holds the operator’s licence from the Gambling Commission for remote general betting. Verdict for the punter: Swifty is the right book for horse racing and football accumulators without a same-game leg. The price book is the standard one for a book of this size, the BOG is the differentiator on racing days, and the verification flow is the standard one.

Octobet — racing-led book with a £150-per-race BOG

Octobet’s offer is Best Odds Guaranteed on UK and Irish horse racing, with a £150 stake cap per customer per race. The cap is the line a punter with a planned long stake must read before they strike: a tenner on every leg is unaffected, a hundred pounds on the favourite in a feature race is unaffected, but a large stake on a single horse in a smaller race will be capped.

Octopus Game Limited carries the Commission licence for remote general betting (real events). Verdict for the punter: Octobet is the racing book for the punter whose accumulators are mostly small-stake and frequent on UK and Irish racing, where the BOG pays out the difference between SP and the early price if the early price is shorter. A punter with a planned big stake on one leg in one race will look elsewhere.

BetGoodwin — three welcome tokens, one of them an acca

BetGoodwin’s sports welcome offer is structured as three free bets of £5 each: a £5 sports bet, a £5 acca free bet and a £5 Sub-Cover bet, in exchange for a £10 qualifying stake at minimum odds. The acca slot is the position the operator has built its welcome around, and the offer is the operator’s identity in this comparison: three small free bets, each on a different bet class, none of them large.

Goodwin Racing Limited is the Commission-licenced operator for remote general betting. Verdict for the punter: BetGoodwin is the book that has decided to take new customers with a structured acca welcome rather than a straight free bet. The welcome is small, the acca slot is built in, and the rest of the price book is smaller than the bigger operators’ on everything except racing.

Betfred — Bet Builder, Extra Places, Racing Post data

Betfred is the longest-running brand in this comparison, and the feature set on the app matches that heritage. Bet Builder and Sub Switch (an edited multi-substitution tool), Racing Post data on the racing side, Extra Places, in-play and a casino and bingo product sit under the same licence. Accumulators on football and racing are the main book, with promotions on those two sports running most weeks.

Petfre (Gibraltar) Limited acts as the licence holder for remote general betting. Verdict for the punter: Betfred is the multi-feature book in this comparison. The price book is not the longest on the market, but the depth of product and the data integrations are the differentiator, and a punter with a racing accumulator that wants Extra Places on every leg will find the offer already loaded.

BetUK — free bets with a sport-and-region restriction

BetUK’s welcome offer, like BetGoodwin’s, is built around free bets at minimum odds, and the operator’s terms exclude virtual sports, esports and non-UK/IE horse racing from the qualifying conditions and from the use of the free bet itself. The minimum-odds rule on the free bet is the same as every other book; the sport restriction is the part to read before claiming the offer.

LeoVegas Gaming PLC maintains the remote general betting licence issued by the Commission. Verdict for the punter: BetUK is the book for the punter whose planned accumulator is on football, UK and Irish racing, or mainline sports, with no esports or virtuals in the legs. The exclusion is on what counts toward qualifying and on what the free bet can be spent on, and it is the line that decides whether this offer sits beside the others.

Acca bonuses and free bets, and what each one takes to clear

The marketing of accumulators in Great Britain runs on three product names — acca insurance, acca boosts and acca free bets — each of which sits inside the 10x cap on bonuses and the standard Commission rules on free bets. The offers are described qualitatively in this section; the codes and the up-to-date figures are operator-side and outside the page.

How a “free bet” on an acca actually settles

A free bet has two key rules: the stake is usually not returned with the win, and the offer expires on a date the operator sets (commonly seven days for a sports free bet). A £5 acca free bet at minimum odds of, say, 1/2 (1.50) per leg, on a five-fold of 1.50 prices, gives a return of £5 × 7.59 = £37.97 if every leg wins; the punter does not see the £5 stake come back. The promise is the winnings of an accumulator paid for by the bookmaker; the cost is the punter’s full qualifying stake at the front, which itself is staked at minimum odds.

Where the offer is “money back as a free bet if one leg lets you down” (sometimes labelled “acca insurance”), the refund is a free bet in the same shape — stake not returned, expiry the same seven days, and the winnings of the refund are paid on whatever the punter chooses next. The minimum price for the qualifying bet, and the maximum refund the operator will issue, are the conditions the punter should read first.

Whether acca freeze works on a free bet is a per-operator answer

Acca freeze is the cash-out feature. A free bet is a free bet — the operator’s terms decide whether it is cash-outable. Most licensed operators treat the stake of a free bet as non-withdrawable and therefore the bet itself as non-cash-outable, because the cash-out price would be derived from a stake the punter did not pay. Where the operator offers cash out on a free bet, it states the rule on the offer page; where it is silent, the default is no. The punter should not assume it.

Acca edit is the same story with a different mechanism: an edit replaces one or more legs and the new bet is settled as a fresh accumulator. Where the operator offers it, it covers selections that started on the same bet; where it does not, the punter voids the bet and re-stakes. Free-bet edits are operator-specific and rare, and the punter should check the operator’s terms before planning around the feature.

The 10x cap and what it does to a “big” welcome

The 10x cap applies to the wagering requirement on a bonus. A £10 bonus with a 10x cap needs £100 of qualifying bets before withdrawal — a constraint that puts a ceiling on the “£500 free bet” type headline, which would have needed £5,000 of bets. The cap is binding on a bonus with a real wagering requirement; a free bet with no wagering condition is not affected, and neither is a price boost (which is settled at the boosted price with no further play-through). Mixed-product promotions — a free bet tied to a casino signup, for example — are banned outright.

The upshot for the punter: a “free” headline is read at the value of the qualifying stake, the time it takes to clear, and what happens to the stake. A £5 acca free bet that settles at the £37.97 number above is about the qualifying £10 the punter has already paid, not the £5 token, and the page does not dress the offer up.

Setting a stake on a single leg

The size of a stake is not licensed. Operators set their own maximum stakes, and on a heavily-favoured accumulator leg the maximum can be small for new or untested customers. Operators also carry the right to restrict, and a high-volume accumulator punter can find the limits tightened without notice.

The punter’s stake is the punter’s choice; the operator’s stake cap is the operator’s. The £150 BOG cap on Octobet, the daily maximums at other brands and the in-play limits inside the bet builder are all the same fact seen from different books. None of them are about risk on one bet — they are about sizing the account, and a punter who reads the operator’s terms before staking reads the right thing.

The safer-gambling frame around the accumulator

Every licensed bookmaker in this comparison runs inside the same safer-gambling framework: GAMSTOP exclusion, GamCare referrals, identity verification before deposit, and the Commission’s financial-vulnerability check. The framework does not change the bet; it changes the conditions around it.

GAMSTOP and the self-exclusion route

GAMSTOP is the national multi-operator online self-exclusion scheme and a mandatory licence condition for online operators since 31 March 2020. Exclusion 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. The scheme covers online sites and apps; betting shops use a separate service.

An excluded customer will not pass the identity check at the licensed site. That is the point of the framework. Self-exclusion does not run on an operator-by-operator basis; the punter registers once and the registration applies across the licensed market.

Vulnerability checks and the £150 rolling deposit threshold

A financial vulnerability check (LCCP condition 3.4.4, in force since 30 August 2024) applies to licensed remote betting when a customer’s deposits minus withdrawals exceed £150 in a rolling 30 days, since 28 February 2025. The check is a public-record check (bankruptcy, county court judgments, IVAs), not an income check and not a credit reference check. Financial risk assessments are at the announced, staged, no-start-date stage of the Commission’s plan.

A punter who reaches £150 in net deposits across 30 days at the same book will see the check. None of this changes the bet — it changes the conditions the customer plays under, and the punter who cares about the difference reads the operator’s safer-gambling page before the limit is reached.

Where to get help

GamCare runs the National Gambling Helpline. GambleAware funds the National Gambling Treatment Service and the clinics. The NHS operates gambling clinics in several regions. Gamblers Anonymous runs peer-support meetings. The Commission’s own safer-gambling pages cover a customer’s rights to refunds, complaints and dispute resolution. These are the services a punter should know about before a session goes wrong; they are not the work of the comparison above, and the comparison above does not claim to replace them.

What an accumulator comparison is for

The ten licensed bookmakers above cover the spread of a Great Britain accumulator market. None of them is the cheapest, deepest and most socially-innovative at the same time; each one is a position on that triangle. Bet365 takes the in-play depth. Kwiff takes the surprise boost. Betfred takes the multi-feature book. Fitzwilliam takes the average price. Octobet and Swifty take racing accumulators. Dabble takes the social book. BetGoodwin and BetUK take a structured welcome. Geoff Banks takes ante-post racing. None of them is “the only” licensed choice; this is the licensed set, and a punter picks by what they actually want to bet on.

The composition of a winning accumulator is the same at every book — every leg must win, a push removes the leg, and the price is the product of the prices. What changes between the books is the depth of the offer, the in-play book, the bonus attached, the social features, and the verification flow. None of those changes the bet, and all of them change the customer experience of making it.

Frequently asked questions

What is an accumulator bet?

An accumulator is a single bet that links two or more selections, with all of them required to win for the bet to be paid out. Decimal odds are multiplied together to give the combined price, and the stake is multiplied by that combined price to give the return. The same bet is called a parlay, an acca, a multi or a combo bet in different parts of the English-speaking world.

How do accumulator bets work?

Each leg is a separate selection with its own price, and the bookmaker takes a margin on each leg before the legs are combined. The bet wins if every leg wins, loses if any leg loses, and where one leg pushes (a dead heat in a place market, the totals line landing exactly) the leg is removed and the bet is settled on the remaining selections at the reduced price. Cash out pays the bet off before every leg has run, at a price the bookmaker offers.

Can acca freeze be used on a free bet?

The freeze is the cash-out feature. Whether it is available on a free bet is a per-operator decision that sits in the offer’s terms; most licensed operators treat the stake of a free bet as non-withdrawable and therefore the bet as non-cash-outable, and the punter should read the offer page before assuming otherwise.

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

The Commission’s public register is searchable by business name, trading name, account number or domain. The licensed account number and licence holder are on the page for each operator above, and the register is the test. A licence is permission to operate under the Commission’s licence conditions, not a recommendation.

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

For decimal odds the return is stake × price; the profit is the return minus the stake. The combined price of an accumulator is the product of the leg prices, and the return is the stake multiplied by that combined price. Fractional odds of a/b convert to decimal as a/b + 1, and the rest of the arithmetic runs the same way.

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

The margin is the difference between the implied probability of all outcomes on a market and 100 per cent. Divide each price into 1, add the reciprocals together, and the excess over 1 is the margin. For an accumulator the margin compounds with each leg, and a five-fold with a 6 per cent margin on every leg carries a combined margin of roughly 27 per cent. Higher margin means more of the stake is taken by the bookmaker; lower margin means the punter keeps more of a winning bet.
