What is the Football Acca Boost?
The Football Acca Boost is a long-running promotion that rewards your
winning football accumulators with a
The promotion is available online and in shops, covers key football markets (90 mins, BTTS, Over/Under, etc.), and requires no opt-in. As long as your acca meets the criteria, the boost is applied automatically at settlement.
How it works (step by step)
1. Build a qualifying football acca
- Create a football acca with 4 or more selections.
-
Every leg must be from the Promotion Markets:
- 90 Minutes
- 90 Minutes 2 Up
- Both Teams To Score
- Match Under/Over Goals
- Each selection must be priced at 1/5 (1.2) or bigger. If any leg is below 1/5, the whole bet does not qualify.
- Stake must be cash (any amount, no minimum stake) – not Free Bets.
2. Place your bet online or in-shop
- Online: via the William Hill website or iOS/Android apps.
- Retail: via a Sports Betting Terminal or over the counter on Smart Hub SSBT.
- Standard over-the-counter paper slips in shops do not qualify.
3. Let the acca settle
- If all selections win and the acca remains 4+ legs, your profit (winnings minus stake) receives the Acca Boost percentage.
- The extra is paid in cash, alongside your normal returns, as part of the settlement process.
- If your acca loses, there is no refund – this is a winnings-boost offer, not insurance.
4. What happens with void legs?
- If one or more selections are void, the acca is recalculated with the remaining legs.
- The Acca Boost still applies, but the percentage is based on the final number of winning selections.
- If your acca drops to 3 selections or fewer, it loses “Qualifying Acca” status and the boost will not apply.
Acca Boost percentage table
Your boost percentage depends on how many qualifying selections are in your winning acca.
| Number of selections | Acca Boost on winnings |
|---|---|
| 4 selections | 5% boost |
| 5 selections | 7.5% boost |
| 6 selections | 10% boost |
| 7 selections | 15% boost |
| 8 selections | 20% boost |
| 9 selections | 25% boost |
| 10 selections | 30% boost |
| 11 selections | 35% boost |
| 12 selections | 40% boost |
| 13 selections | 45% boost |
| 14 selections | 50% boost |
| 15+ selections | 100% boost (double winnings) |
The maximum Acca Boost per bet is £2,000 in shops and £10,000 online. There is no daily limit on how many Qualifying Accas you can place.

Fair play & responsible betting
- William Hill may cancel bonuses, void bets or remove winnings if it detects unfair play such as minimal-risk wagering, collusion, exploiting loopholes or abusing personalised offers.
- Promotions are for eligible customers only; excluded players, or those flagged for safer gambling reasons, may not participate.
- Remember that more legs means lower hit rate. Treat the boost as a nice extra, not a reason to over-stake.
- Set clear limits on your acca stakes and if betting stops being fun, consider using deposit limits, time-outs or self-exclusion tools.
