Acca Freedom gives every existing customer a daily acca token. The token can be applied to an accumulator in your bet slip to either boost your potential payout or insure your stake against a losing leg (only one can be chosen each day). If you choose bet best new customer offers bookies to boost your acca bet with the token, it must have a minimum of 3 legs and the maximum stake is £20. On the other hand, the acca insurance option can only be applied to an accumulator consisting of 5 legs or more (each selection must have minimum odds of 1/5). If one leg loses and all others hit, you get a free bet equal to your losing stake up to £20. On selected ante-post and race-day markets, William Hill offers your stake back as a free bet if your selection is declared a non-runner. Applicable races are flagged with an “NRMB” tag.

The bookmaker was ordered to pay a record £19.2 million fine by the UKGC in 2023 for KYC issues. In fact, the Gambling Commission seriously considered suspending William Hill’s licence before the bookmaker acknowledged its role in the failures and moved quickly to address them. I found William Hill to be one of the best bookmakers for bonuses, with a solid sports welcome offer and several good existing customer promotions, especially for accumulator bettors. The promos I took advantage of most during my William Hill review were the Reward Hub, Acca Freedom and Acca Club offers. First, I’ll break down William Hill’s two welcome offers (sports and casino), then I’ll go over every promotion available to existing customers. Bonus Drop is a free daily game giving existing customers a chance to win free spins, casino credits, cash, or a free bet. Players drop a disc down a pegboard, and it can lead to one of three spots: Win, No-Win, or Retry. Prizes are awarded randomly, and Friday prizes can be multiplied depending on how many times you’ve played Bonus Drop throughout the week.
