10/10
Arguably the biggest betting firm in Britain, the pressure is on William Hill to stay top of the pile and they do so by claiming they offer more top prices than the competition. This is focused more on football odds but they are more than competitive with their horse racing prices. They promote betting with a difference and each day line up a host of daily specials ranging from match bets and enhanced doubles to winning distances & favourites betting. Understandably, they also offer Best Odds Guaranteed on UK and Irish racing - every race, every day.
