William Hill Acca Boost: Get Up to 200% Extra on Accumulator Winnings

William Hill has given accumulator bettors an extra reason to build their weekend multiples, with its Acca Boost offering up to a 200% boost on winnings from qualifying football accumulators. The promotion is available both pre-match and in-play, while NFL accumulators are also included on selected markets.

One of the strongest aspects of the promotion is its simplicity. There is no opt in and no minimum cash stake, with the boost applied automatically when an eligible accumulator meets the qualifying conditions. For football, customers need at least two selections at minimum odds of 1/5 per leg, using qualifying markets including 90 minute match betting, 2 Up, Both Teams to Score and match over/under goals.

The More Selections, the Bigger the Boost

William Hill rewards bettors for building larger accumulators, with the boost rising on a sliding scale as more selections are added. An acca with two legs receives a 3% boost, rising to 7.5% for five selections, 20% for eight and 30% for ten. The increase becomes particularly significant for bigger accas, with 15 winning selections earning a 100% boost, 18 selections receiving 150%, and an accumulator containing 20 or more winning selections qualifying for the headline 200% Acca Boost. If you prefer enhanced prices on individual selections rather than multiples, our price boosts page rounds up the best boosted odds available today.

The boost applies to the winnings rather than the original stake and is added automatically as part of the normal settlement process. Online customers can receive a maximum Acca Boost of £10,000 per qualifying accumulator, while the retail maximum is £2,000. There is also no daily limit on the number of qualifying accumulators customers can place.

Football and NFL Acca Boosts

Football provides plenty of scope to use the promotion without having to rely exclusively on match result selections. Both Teams to Score and Over/Under Goals are included alongside William Hill''s standard 90 minute and 2 Up markets, making it possible to build an accumulator around several different types of football prediction. NFL customers can use Money Line, Spread and Total Match Points selections in the same way.

Accumulators remain popular because they allow several relatively short priced selections to be combined into one potentially much larger return, and the Acca Boost adds another layer by increasing the winnings when the complete bet lands.

The fact that the promotion starts with just two selections also means it is not exclusively aimed at bettors chasing enormous 15 or 20 team multiples.

Exclusions to Remember

There are some important exclusions to keep in mind. Free Bet stakes cannot be combined with the Acca Boost, while an accumulator that has been cashed out will no longer qualify. Void selections can reduce the applicable boost according to the final number of winning legs, and an accumulator reduced to a single selection loses its qualifying status.

The promotion runs until 23:59 UK time on 30 May 2027 and is available to eligible William Hill customers in the UK and Ireland, as well as UK retail customers placing qualifying bets through Sports Betting Terminals.
