Best Accumulator Bonuses From UK Betting Sites

Accumulators are some of the most popular bets to place at UK online bookmakers, but sports fans up and down the country may not realise how many betting bonuses there are out there.

Due to the extremely high levels of competition in the industry between betting brands, in order to attract new users and retain existing customers, top-value promotions are offered.

As a result, a variety of accumulator bonuses and special deals such as acca insurance are now available to be claimed at online bookmakers in the UK, across a range of sports and markets.

As there are so many options out there when it comes to betting bonuses, it can be hard for sports fans to keep up to date with the latest offers - and work out whether they are good value.

After all, the small print of the terms and conditions always needs to be checked as the details can include things that would put a player off from using a betting bonus if they were to spot it.

Without further ado, let's take a look at some top accumulator bonuses from UK bookmakers.

bet365

Bet365 Accumulator Bonus

Bet365 is famous for its betting bonuses, so there is no surprise it has a great acca bonus too.

Tennis fans can get a boost on their winnings of up to 70%, depending on how many selections they add to their betslip. Doubles will get a 5% increase, which rises to 10% for trebles, 15% for four-folds, 20% for five-folds and so on. Top tennis competitions such as any Grand Slam, ATP, WTA or Challenger Tour event are covered here.

A similar top acca bonus deal is in place for football, with trebles getting a 5% bump. Bet365 has made the acca bonus available for 80 competitions, including the Premier League.

William Hill

William Hill Acca Freedom

Acca Freedom is the William Hill version of this type of promotion, with two different strands. First up, William Hill customers are able to boost the odds of trebles and above to win more.

There is also the option to claim acca insurance, with William Hill offering to give users a refund on their stake up to £20, paid as a free bet, if one leg lets them down for a winning wager.

In order to qualify, William Hill customers need to place an acca with five or more selections and each selection must also be made at odds of 1/5 (1.2) or bigger as well.

BoyleSports

The acca bonus offer at BoyleSports is fairly similar to what is on the table from William Hill.

BoyleSports customers can get a boost of up to 100% on their bets if they make 14 or more selections in their wager, with the deal starting at a 10% boost on five-folds. As is the case at William Hill, BoyleSports customers who want to qualify must ensure that each selection is made at odds of 1/5 (1.2) or bigger as well.

BoyleSports also has a form of acca insurance too, with up to £20 refunds paid out as a free bet here in the event that one leg lets down an accumulator with five or more selections.

Traditional British betting brand Betfred is known for its bonuses, with those who love to place accumulators able to get a top deal on this site.

Betfred is offering football fans who place a bet with five or more selections a refund of up to £10 in the event that just one leg lets them down. Various markets are covered like HT/FT, BTTS and total goals and each selection must be made at odds of 1/5 (1.2) or bigger.

However, what makes Betfred acca insurance stand out from the crowd is the fact that the refund of up to £10 is paid out as cash here, rather than as a free bet as it is elsewhere.

When adding qualifying acca bets to their betslip, Ladbrokes customers will also see the option to boost their odds, increasing the potential profits that are up for grabs from this type of bet. For the odds boost offer, there is a maximum stake of £50 that will be paid at the increased price.

Different Types of Accumulator Bonuses and Features

Sports fans using UK online bookmakers might not realise that there are a few different types of accumulator bonuses and features to look out for. Here, we have broken down the top options:

Acca Bonus Offers

This is an umbrella term that is often used to describe any type of betting bonus that covers accumulators, with various types included. However, an acca bonus boost is the most popular type of offer out there, with some UK online betting sites offering their users up to 77% extra winnings on their accumulators as long as some certain conditions are met.

Acca Insurance

One of the top betting bonuses of recent years has been the rise of acca insurance. All sports fans who like to place a bet have probably experienced the pain of being close to landing a big bet only for a late change of score to leave them with one losing leg.

With acca insurance, as long as qualifying conditions are met when placing the wager - there is usually a minimum odds per leg requirement - customers get a refund if just one leg is a loser. It is often repaid in the form of a free bet, but sometimes acca insurance does pay out in cash.

Free Bet Clubs

Some top online betting sites in the UK now offer customers who place accumulators on a regular basis a free bet per week as a reward for their loyalty. As a top example, Betway users can get £10 in free bets every week by staking £25 on acca wagers.

Acca Cash Outs

A popular feature on most major betting sites these days, cashing out is normally available on accumulator wagers for sports such as football and tennis. When cashing out, players have a chance to lock in some guaranteed profit from a wager, or maybe cut their losses. There are pros and cons to acca cash outs, with sports fans who take an offer early then find that the wager would have gone on to be a winner perhaps wishing they had let it ride.

Acca Bet Builders

Many betting sites now offer their customers a bet builder option, which can be treated as a form of accumulator for the same game. For example, a betting brand might let a user create their own acca by picking a football team to win a game, naming the first scorer and what the final result will be. These acca bet builders are only going to get more popular.

Edit Acca Options

One recent development in the world of accumulator bonuses has been betting sites giving their customers the chance to edit their acca after the bet has been placed. Giving customers a new level of flexibility over their wagers, editing acca bets are likely to be something that an increasing number of UK online bookmakers look to add in the near future.
