Bet Boosts Explained:

As ever, there are a few things worth noting when using bet boosts, starting with the fact that ‘flash odds’ or ‘enhanced odds’ – both existing William Hill promotions – cannot be used in conjunction with it. Also, free bets cannot be used when applying the bet boost – either using a part-value or full value of the free bet.

If you use William Hill’s cash-in facility for any of the bets covered by the boost, any winnings will be based on the original price, not the boosted one, and the daily bet boost must be used in full and only once per day.

For each-way bets, the boost will only be applicable to the winning element of the bet, and if the bet qualifies for Bet Odds Guaranteed – another William Hill offer – the bet will be settled, as per the promotion, at the best odds available and not the boosted odds.

The amount your odds are boosted depends on the selection you make. No formula for working out what your boosted price will be is available – the new odds are at the discretion of William Hill.
