Top Accumulator Betting Sites 2021:

The bookies in the table above were chosen as a result of stringent testing from our team of dedicated experts. We looked at many things from odds percentage to the events available, which we will address in the coming paragraphs.

What is an Accumulator Bonus?

An accumulator bonus is ometimes known as an ‘acca boost’, it is simply and odds boost to your accumulator bet. This means, the bookmaker will increase you payout by a certain percentage, to what would have been the normal payout.

The Criteria for the Best Betting Sites for Accumulators

When it comes to analysing a bonus of any type, there has to be some form of standard to assess them with. It goes with without saying, things like payout, minimum odds, and other requirements are all important. In the boxes below, you can see a more in-depth explanation.

Although you may have seen our page on the no deposit bonus, this offer has different criteria to be judged by. It is essential that you take each promotion and analyse them individually, rather than making a wholesale general statement. That’s why we have these specific categories below.

The Maximum Percentage You Can Utilise

Many of the best accumulator betting sites will cap their promotion at a certain level, this will be then the maximum percentage. Naturally, the higher it is, the better your returns. The max we found so far was 80%, so if you find one around that level than you will be on to a good one!

The Minimum Percentage You Can Receive

On the contrary, there will also be a minimum percentage that you can receive. This is generally based on the number of selections in your acca. The lowest we found was starting at 2%, but we also saw starting offers at 4%. In general, this is a pretty small amount and wouldn’t give you much of a boost at the end of the day.

The Amount of Events Needed (Min and Max)

As is expected, the best bookies for accumulators have certain rules and regulations in place. This means there are a minimum and maximum number of selections needed on your betslip in order to partake in the bonus. This is usually from 3 selections to 25. This is pretty standard across all of the offers.

The Minimum Odds of the Selections

It is often the case that an accumulator bonus will include the stipulation that each selection must be at odds higher than a certain amount, along with the cumulative selections. For an individual one it can be around 1/5 (1.25), and then overall it should be 3/1+ (4.00). Obviously, this depends wholly on each offer, so read the T&C’s.

The Sports, Events and Betting Types You Play on Your Acca

This type of offer is generally allowed on most sports and is perfect for football. Usually, the exception is on horse racing and greyhounds. The best betting sites for accumulators generally have a whole host of sports and events on offer, so you won’t be left wanting for choice, something that is integral to your enjoyment.

Often times the offer is restricted to straight-line accas, on in other words single bets accumulated. However, there may be some exceptions. Things like the ‘win’ part of an each-way bet may be boosted, it is enitrely dependent on the specific bookie and there relevant terms.

The Advantages and the Disadvantages

Like any type of betting bonus, there are always some pros and cons to what is on offer. The best accumulator betting sites are no exception. The main advantage is clearly that you can dramatically increase your potential winnings from your acca.

However, it must be noted that in order to receive a larger percentage boost, you need to have more selections on your betslip. This inevitably means you will face more risk of your bet losing, thus not winning anything at all. This is clearly a big disadvantage to you.

How to Claim an Accumulator Bonus

When we accessed the best bookmaker for accumulators UK, we decided it would be a good idea to create a step by step guide for you in order to claim the promotion. Below, our dedicated experts have done exactly that for you.

In following these general steps, you will be able to claim an acca offer at most sites. Of course, there may be slight specificities depending on the bookie, but this is a very good starting point. As we always say to our punters, please read the T&Cs before you commit to anything.

The Best Betting Sites for Accumulators

Many of you are probably familiar with our list of best betting sites, but what about the top bookies for accumulators? The five listed below are simply the ones you should use. We will explain why throughout our detailed descriptions.

Karamba Accumulator Bonus: The Acca Boost

The Accumulator Bonus of Karamba
Bookmaker: Karamba
Website: www.karamba.com
Max Bonus %: 77%
Max Events: 15
Min Odds: 3.00 / 1.20
Min Bonus %: 4%
Min Events: 4

The Karamba bonus is our favourite of the bunch. They call it the ‘Karamboost’, and any accumulator with four selections is eligible. It’s a great little boost that goes up in stages.

The minimum odds of 1.20 for each individual selection is more than reasonable. The way the boost works is that for four selections you get 4%, for five you get 7% for six it is 10%, and it works all the way up to 77% for 15 selections. Overall, we really like the offer and it gives you the ultimate choice and flexibility in how you want to play your acca.

William Hill Accumulator Bonus: The Big Bet Boost

The Accumulator Bonus of William Hill
Bookmaker: William Hill
Website: www.williamhill.com
Max Bonus %: n/a
Max Events: 25
Min Odds: n/a
Min Bonus %: n/a
Min Events: 3

Now we move on to the William Hill bonus and see that this is also an enticing offer. The maximum stake that can be boosted is £20, other than that there aren’t many stringent guidelines you have to adhere to.

You can bet on any sport, other than horse racing or greyhounds, so get your football bets ready. You can even place an each way bet, with the win part being boosted. This is something that isn’t available at every bookie and is certainly a positive of this offer. We could not find any minimum odds, the only stipulation being that you have to place a minimum of three selections, which is pretty standard.

Ladbrokes Accumulator Bonus: Bag the Best

The Accumulator Bonus of Ladbrokes
Bookmaker: Ladbrokes
Website: www.ladbrokes.com
Max Bonus %: n/a
Max Events: n/a
Min Odds: 4.00 / 1.25
Min Bonus %: n/a
Min Events: 5+

The Ladbrokes bonus is a unique offering. They have a three-part promotion. Firstly, the acca insurance means that if you have a 5-leg+ acca, if one loses, then you will get your money back in terms of a free bet.

Then, the so-called ‘tack’ feature, allows you to edit your acca once you have placed the bet. You can do this in-play, and delete losing legs! This is a great and unique feature.

Lastly, the ‘boost’, gives you an extra percentage on top of your winnings. We could not find any specific info here, however, it is most likely a case by case scenario.

Paddy Power Accumulator Bonus: The Insurance

The Accumulator Bonus of Paddy Power
Bookmaker: Paddy Power
Website: www.paddypower.com
Max Bonus %: n/a
Max Events: n/a
Min Odds: 3.0 / 1.25
Min Bonus %: n/a
Min Events: 4

Now, let us get to something a little bit different. The Paddy Power bonus is not a boost. Instead it is an insurance against your bet losing. Basically, they say if one leg lets you down, they will cover you stake up to £10.

All you have to do, is place an acca of 4+ legs. The minimum odds per selection is 1/5 (1.25). Then if you one selection doesn’t come through, you’ll then get a free bet to cover the stake amount.

You have to use it within seven days, but it’s a pretty good offer and gives you a little bit of a backup when going for those weekend accas.

Coral Accumulator Bonus: 10% Boost

The Accumulator Bonus of Coral
Bookmaker: Coral
Website: www.coral.com
Max Bonus %: 10%
Max Events: n/a
Min Odds 2.50 / 1.25
Min Bonus %: 10%
Min Events: 3

The Coral bonus is a pretty decent offer. Like all accumulator bonuses, there are some rules and regulations to follow. Namely, you need to place an acca the comprises of at least three separate events. In doing so, you will then be eligible for a boost.

This applies to your first football accumulator every day. You will then receive 10% up to £100 when you win. This will then be paid out in the form of a free bet.

You can only play on the football, so it is a little restrictive compared to others, even so we were very impressed with the frequency of this deal.

Below, you can find some of the most freqeuntly asked questions. If you want to get in touch, please do at info@bestbettingsites.com and we’ll get back to you.
