Best Odds Guaranteed is one of the most common promotions when it comes to horse and greyhound racing and is therefore something every punter who wants to get the most out of their bets should be utilising.

William Hill offer Best Odds Guaranteed on all UK & Ireland horse and greyhound racing so if you take a price on a horse or greyhound and the Starting Price (SP) is bigger, then William Hill will settle your bet at the bigger odds.

For example, if you take a price on a horse at odds of 15/1, but the SP is 20/1, then you’ll be paid out at the bigger price of 20/1.

The offer is available online and via the William Hill mobile sports app and is open to new and existing customers.
