Accumulator Bonus at UK bookmakers
Checked 17 August 2026
What is an accumulator bonus?
An accumulator bonus, or acca bonus, adds a percentage to your winnings on a winning multiple, with the boost usually rising as you add more selections. Some bookmakers pay it as cash, others as a free bet. It rewards you for combining several bets into one accumulator rather than backing them singly.
Acca insurance explained
Acca insurance is the flip side: if one leg of a qualifying accumulator loses, the bookmaker refunds your stake, typically as a free bet up to a set amount. Terms vary on the minimum number of legs and the minimum odds per selection, so check those before you place.
What to check first
Look at the minimum number of legs, the minimum odds per leg, whether the reward is cash or a free bet, and any maximum payout. A generous headline percentage is worth less if the qualifying terms are hard to meet.

How many selections do I need for acca insurance?
Most acca insurance offers require a minimum number of legs, often five or more, each at a minimum price. The exact figure is set by the bookmaker, so read the offer terms.
