The Best Accumulator Betting Sites UK 2025

The Ins and Outs of Accumulator Betting

Before we get into the finer details of accumulator betting and show you how to claim the best acca bonuses online, let’s first cover the basics. We’ll start by describing exactly what a bet accumulator is, before introducing some of the terms you need to know when placing this type of bet. You’ll then want to stick with us a little longer, because we’ll also show you how to calculate acca betting odds and offer an introduction to each way accas, which is popular with horse racing fans. 

Accumulator Bets Explained

An accumulator is a bet which combines two or more selections into a single wager. In order to win an accumulator bet, each individual selection must win.

Sports betting accumulators are extremely popular among bettors as they offer the possibility of much higher returns compared to collective single bets. Of course, with greater returns comes greater risks – just one losing selection in your accumulator means the whole wager is lost.

You can build an accumulator bet using events from most top sports at the best online bookies, combining fixtures across different match days and even crossing over to different sports. What’s generally not allowed at a number of sportsbooks, however, is choosing multiple selections from the same event. 

These bets can instead be placed using special custom markets such as PaddyPower’s #WhatOddsPaddy and Ladbrokes’ #GetAPrice, where customers can request odds on same game multiples, amongst other markets, using Twitter. While these custom bet builders are becoming increasingly popular, they’re less common at new betting sites.

Doubles, Trebles and Beyond

You’ll find there isn’t much to take note of when it comes to types of standard accumulator bets. The only variable here is the number of selections. To begin with, accumulators with only two or three selections are known as ‘double’ and ‘treble’ respectively. While the returns on these are relatively modest in comparison to a huge accumulator with 10 or more selections, they’re both simple, solid options to add your bet slip. While combining multiple selections could give you a tidy odds boost, having just two or three selections means you’re mathematically more likely to win, as there are less possible outcomes.

Once you progress beyond three selections, a bet with four selections is known as a four-fold accumulator, a bet with five selections is a 5-fold accumulator, six selections for a six-fold, and so on. To limit any potential losses on their end, most bookies impose their own cap on the number of legs you can add to your accumulator.

Same Game Accas

Offered at the best accumulator betting sites, same-game accas combine multiple bets on a single match into one wager. This is unlike standard accas which are usually placed across different events.

Football is one of the most popular sports for same game accas thanks to its diverse selection of markets. Take a Euro 2024 qualifying match between Ukraine and Italy for example. You might like to combine the following bets:

• Both teams to score (BTTS) – 5/6
• Over 9 corners – 6/4
• Ruslan Malinovsky to be booked – 11/10

The odds of this treble are multiplied to give 8.62/1. 

Same-game accas can be a little difficult to construct, as markets can’t always be combined due to the fact the outcomes affect one another. That’s where the bet builder enters, a feature found at all the best accumulator betting sites. It works in a similar way to a same-game acca, but the odds are calculated using an advanced algorithm based on the chance of all legs succeeding. 

You could place a bet builder on a Champions League match between PSG and Newcastle, for example:

• PSG to win the match;
• Both teams to score;
• Even number of goals.

When we plugged these markets into bet365, the bet builder odds ended up at 17/2.

How to Calculate the Odds of an Accumulator Bet

When betting online, your accumulator odds are virtually always calculated for you. As soon as you add two selections to your betslip, the option to place a ‘double’ bet will appear. More options will become available as and when you add more selections.

If you ever need to work out the odds yourself, or simply want to know how your accumulator odds are calculated, all you need to do is multiply the prices of your selections in their decimal format.

Here’s an example of a four-fold football accumulator:

• Southampton @ 3.0 to beat Huddersfield
• Liverpool @ 2.0 to beat Watford
• Manchester and Arsenal to draw @ 4.0
• Norwich @ 2.0 to beat Ipswich

To calculate the price you can expect for your accumulator selections, simply multiply the decimal odds.

• 3.0 x 2.0 x 4.0 x 2.0 = 48.0

So, a winning £5 accumulator bet would result in £240 earnings including your original stake.

Each Way Betting

If you fancy a flutter on the races and don’t want to be let down by an unfortunate photo finish, then an each way bet is definitely worth a shot. An each way bet is essentially two bets – one for your selection win and another for your selection to place. Each bet is an equal stake, so a £5 each way bet, for example, will have £5 on your selection to win the event and £5 on your selection to finish either first, or in one of many places, such as 2nd, 3rd and 4th.

Whether you’re betting on horse racing, greyhounds or even the outright football betting markets, you’ll receive a full payout if your pick wins, and a fraction of this payout if your pick places. 

Different bookies will pay out on a different number of places, so be sure to check out the terms and conditions of each way betting at your chosen bookie before you add to your bet slip.

You can place an each way accumulator, too. Here, you’re still placing two bets – one for all of your selections to win and one for all of your picks to place. If one of your picks does neither, the bet is lost.

Accumulator Betting Bonuses and Promotions

Bookies usually offer a range of bonuses and promotions, and you’ll see a fair few tailored to accumulator betting. From acca insurance to enhanced accas, we’ve listed some of the most common types of accumulator bonuses and promos below, along with some of the benefits and drawbacks of each. Let’s take a look.

Acca Insurance

How many times have you been just one result away from landing a huge accumulator win? Some bookies have given punters some room for error with their generous ‘acca insurance’ offers. These promotions see top betting sites pay out on winning accumulators as well as those with one incorrect selection.

This promotion isn’t always available on every market and is usually offered on five-fold accumulators and above, but it’s a great safety net to fall back on should your accumulator fall short. With a typical insurance offer, you’ll receive your stake back as a free bet token.

Accumulator Bonuses

A number of top bookies also offer bonuses on winning accumulators. This is usually referred to as an acca bonus or parlay bonus. The concept is simple – the more selections you include in your accumulator, the more your bookie will add on in bonus funds. Bet365 are well known for their football acca bonus promo, which sees treble bettors rewarded with a 5% bonus and 13-folds boosted by a whopping 90% bonus. Similarly, Betfair offers an optional feature called ‘acca edge’. Opting in means that if one result lets you down then Betfair will offer you money back as cash in return for a slight reduction in odds.

Enhanced Accumulators

If you don’t fancy building your own accumulator, you’ll often find that the biggest and best bookies do the legwork for you. Enhanced accumulators are offered on a daily basis at some bookies. This offer sees the bookies pick out an accumulator for you at a higher price than originally offered. All that’s left for you to do is decide whether or not you fancy a flutter.

Edit Bets In-Play

Some operators, such as Bet365, offer players the chance to edit their accumulators in play. This means you can add, change, or remove wagers from your acca for unsettled selections, with the stake of your new bet usually being equal to its current cash out value. Operators that allow players to edit their accas in play have varying rules and available markets for the feature, so it’s best to check the terms and conditions before settling on an operator that offers it.

Welcome Bonuses

Once you’ve signed up to a new site, you might be wondering if your welcome bonus can be used for accumulators. Generally speaking, you should be able to wager your welcome bonus funds in combination with accas. That being said, it’s important to check the terms and conditions for your welcome bonus when figuring out which one suits you best. 

Aside from whether or not your bonus funds are eligible for accumulators, sites often place additional rules on wagering requirements that might make wagering your bonus on accas an inefficient way to unlock withdrawals. If your chosen site includes accas as a way to chip at your wagering requirements, be sure to check what percentage of your wagers will be factored in. Using your bonus funds may also make you ineligible for other accumulator bonuses, such as boosts and acca insurance, so be sure you know the finer points of your operator’s terms and conditions before getting started.

Typical Acca Terms and Conditions

Although placing an accumulator doesn’t typically come with many terms and conditions, there are stipulations that apply to promotions like accumulator insurance and acca boosts. Let’s take a look at the main T&Cs to be aware of.

Winning Limits

There may be a cap on how much you can win from an online betting bonus. Winning limits are more commonly applied to casino promotions, but it’s always worth checking whether there’s a maximum profit on your acca. Some betting sites offer payout boosts for accas of a certain number of legs — in this case, there’s usually an upper limit on the bonus winnings.

Minimum Odds

With offers such as accumulator insurance where you can claim a free bet if one leg of your acca lets you down, there may be minimum odds per selection. Paddy Power’s iteration of this offer, for example, requires minimum odds per leg of 1/4 (1.25) to qualify.

Eligible Sports

Some accumulator bonuses may only apply to certain sports. For example, if there’s an odds boost up for grabs on any football acca, your bet may become ineligible if you add selections from other sports.

Pre or In-Play Bets

Most accumulator insurance offers apply exclusively to pre-match bets, which means your bet won’t be eligible if it includes matches that are currently in play. To be on the safe side, scout out available bonuses in advance and get your acca ready before your selections kick off.

Best Accumulator Bookmakers by Sport

To illustrate how accumulators work best, let’s look at some hypothetical scenarios across a range of popular sports. We’ve kept things simple by using three-fold accas (also known as trebles) as examples, but the same principles apply to larger accumulator bets, whether it’s four-fold, five-fold or even fifteen-fold. Just remember that with every leg you add to the acca, the less likely it is to win. However, you can apply the same principle to a four-fold accumulator, a six-fold accumulator, and so on. 

Best Accumulator Bookmaker for Football

With multiple matches regularly kicking off at the same time, football lends itself perfectly to accumulator betting. Most bookies offer markets on thousands of matches from football leagues and competitions around the world, with many of the top sites also promoting football acca bonuses.

Here’s an example of a three-fold acca on a round of Premier League matches:

• Tottenham to beat Liverpool @2.0 
• Luton Town to draw with Aston Villa @4.0
• Brentford and Crystal Palace, both teams to score @2.0

Acca odds are calculated by multiplying each leg together, which in the above example comes to 16.0 (2.0 x 4.0 x 2.0). A winning £5 wager on these three selections would therefore return £80 (16 x 5). 

If the acca we’ve given above interests you, check out our three recommendations for the best accumulator betting sites for football:

• Sky Bet
• BetMGM
• Betway

Best Accumulator Bookmaker for Horse Racing

The huge number of daily races held in the UK, Ireland, and beyond, combined with the array of runners in each event, makes horse racing a great sport for acca betting. There are many more outcomes possible in a single horse racing event compared to wagering on the result of a football match, where only a home win, an away win or a draw can be selected. Horse racing betting odds are therefore much longer than simple football match result betting, which can be very appealing for acca bettors. You won’t need to select too many winners to be in with a chance of winning decent returns, so a successful three-fold horse racing acca can be very lucrative.

Here’s an example of a simple three-fold horse racing acca:

• Haydock 14.45 – Tippy Toes to win @ 12.0
• Sandown 15.55 – Brazen Belle to win @ 5.0
• Ayr 17.55 – Queen Aminatu to win @ 8.0

Calculating the decimal odds (12.0 x 5.0 x 8.0 = 480) shows that a winning £5 accumulator bet on these horse racing selections returns £2,400 (480 x £5).

You can place accumulator bets like the one above at one of these recommended horse racing bookmakers, all of which offer best odds guaranteed:

• BetMGM
• Unibet
• BetGoodwin

Best Accumulator Bookmaker for Greyhound Racing

Similarly to horse racing, greyhound racing odds will also fluctuate in the build-up to a race, particularly within the final 30 minutes. It’s why most bookies will offer best odds guaranteed on this sport too, lending itself well to acca betting.  

Here’s an example of a three-fold acca you might place on greyhound racing. 

• Doncaster 19.30 – Moss Rosie to win @ 3.13
• Henlow 19.55 – Distant Sean to win @ 4.8
• Brighton and Hove 20:45 – Soul Rebel to win @ 9.0

Calculating the decimal odds (3.13 x 4.8 x 9.0 = 135.2) shows that a winning £5 accumulator bet on these horse racing selections returns £676.08 (135.2 x £5). 

Greyhound racing remains a popular sport to bet on, and you can do so at one of these top sites:

• Mr Play
• Unibet
• BetMGM

Best Accumulator Bookmaker for Tennis

Tennis match result odds on matches featuring the biggest players can be small, given that only two outcomes are possible. The dominance of players like Novak Djokovic in the men’s game has also reduced the number of upsets at major tournaments, so you might need to look at some different betting markets in order to build decent accumulator odds. 

Take a look at the below example, which combines different betting markets across men’s, women’s and doubles tennis matches. 

Here’s a three-fold tennis acca example featuring men’s, women’s, and doubles matches:

• Cameron Norrie v Steve Johnson total games under 21.5 @ 3.0
• Emma Radacanu @ 2.0 to beat Caroline Garcia
• H Watson/H Dart @ 2.5 to be set 1 winners against N Dzalamidze/A Krunic

Calculating the decimal odds (3.0 x 2.0 x 2.5 = 15) shows that a winning £5 accumulator bet on these horse racing selections returns £75 (15 x £5).

And if you’re looking to place accumulator bets on the tennis, we recommend scoping out the following three bookmakers:

• Bet Storm
• Betway
• Bzeebet

Set Your Accas Up on the Go

When placing an accumulator bet, mobile apps have several advantages over desktop sites. For many people, acca betting is more intuitive on a mobile app, with streamlined and optimised interfaces making it easier to both select the markets you want to combine, and review each selection clearly before you confirm the acca.

The other major benefit of placing accas via a betting app is the ability to check in with your selections when you’re on the move. You might even be heading to Anfield or the London Stadium to catch one match, and want to make sure you’re kept up to date on the day’s other results.

This type of betting experience is always enjoyed the most when done via a high-performing bookmaker app. You’ll have the ability to review, edit and cash out your accas while you’re on the go, and at the best accumulator betting sites, you’ll even be able to live stream the game of your choice through the bookie’s app.

Take Advantage of Great Incentives

You might expect to find the most generous welcome bonuses, promotions, and incentives with the industry’s established heavyweights, but often it’s the new kids on the block sending out the brightest calls for new customers. Such sites and operators pop up regularly, each vying for your membership and loyalty, so be sure to keep them in the equation when deciding where to place your first deposit. Once you’ve signed up, new UK betting sites are likely to offer regular promotions for returning customers. Why not take a look at our extensive rankings of the best new sites around, and take a punt on something fresh?

Responsible Gambling

No matter the kind of bet you’re placing, responsible gambling is an integral part of ensuring things remain enjoyable and safe. When you’re betting with accas, there’s an inherently lower chance of your bet succeeding, making it all the more important to exercise strict control over your budget.
