William Hill's Best Odds Guaranteed Explained

Horse racing is probably the biggest sport for UK bookmakers after football, and this is why the best horse racing bookmakers will often launch promotions to make them favourable to punters. The most common example of this is the Best Odds Guarantee (BOG) promotion, and William Hill offers this to customers.

For punters who are unfamiliar with the concept, from 10 am until the race begins, William Hill will offer a 'Best Price Guarantee'. For example, if the Starting Price (SP) is better than the price which you placed the bet at, William Hill will pay out at the highest price thanks to BOG.

The offer applies to single and multiples, and can only be used on the win markets. Regardless of the regulations, this is a fantastic promotion and customers can get lucky if their horse takes off at a higher price than they initially got when placing the bet.

    Make Your Selection(s) and Good Luck!

    The final step is to place your bet and wait for the race to begin. Of course, if there are no positive changes in the odds, your bet will remain at the same odds. However, if the odds rise, then you will be granted the payout from the SP. Good luck!
