William Hill Offers for Football

- Impact Sub – Your bet remains live even if your player is substituted. It simply rolls onto the player who replaces them. This is similar to the bet365 sub on play on offer and runs on bet builders as well as singles.
- Bet Builder Winnings Boost – Place a bet builder and if you’re eligible, you can click the Boost button in your betslip to get an additional 25% winnings on selected matches.
- 2 Up at William Hill – The 2 Up offer at William Hill means you get paid out as a winner if your selected team goes into a two-goal lead. This offer is not as good as the bet365 2 goals ahead early payout, though, because it isn’t available on as many bet types.
William Hill Offers for Horse Racing

William Hill Flash Odds
Sometimes, William Hill will release a ‘flash odds’ promotion. This means you will get the chance to bet on a highly boosted single or multiple across a variety of sports. You can normally expect a flash odds boost ahead of the Saturday afternoon Premier League fixtures or during big horse racing events such as the Cheltenham Festival or Royal Ascot.
When there are flash odds available, we will add the odds to the William Hill price boosts at the top of this page so they’re easy to find.
William Hill Best Odds Guaranteed on Horse Racing
One of the most popular and best William Hill betting offers is their best odds guaranteed on all UK and Irish horse racing. This is the best offer you will find for horse racing, and you should never place a bet at a bookie who does not have it available.
Simply take the price when you place a bet, and if the starting price is bigger, you will get paid out at the bigger odds. For example, If you back your selection taking an Early Price of 4/1 and the SP returns at 5/1, you’ll get the bigger price of 5/1. If the SP returns at 3/1 you’ll still get paid at 4/1.
