William Hill Bet Boost and Epic Boost Explained

The William Hill Bet Boost, along with the Epic Boost, gives punters the freedom to boost the odds of a chosen bet. So, how does it work? Punters at William Hill can use the Bet Boost three times per day: 1x football bet builder, 1x football acca and 1x horse racing bet. The first two need to have at least three selections and the maximum stake is £20 for all three.

William Hill Epic Boost

While there are no exact figures, the Bet Boost could be as much as 10% in some cases, but most of the time the difference between the old and new price is 5-8%. In addition to the Bet Boost, there is also the so-called Epic Boost which can be used three times per week: 1x football bet builder, 1x NBA bet builder and 1x NFL bet builder. These need to have 3+ selections, minimum total odds of 3/1 and a maximum stake of £5.

Pros and Cons of William Hill's Bet Boost & Epic Boost

  • No Winnings Cap: There is no cap on the winnings when using the William Hill Bet/Epic Boost. For example, if you were to score big when betting on football, the winnings would not be cut off.

  • Increased Freedom: The fact that punters can choose the bets they want to boost adds another layer of freedom, which should not be underestimated. It is no wonder that William Hill is regarded as one of the best betting sites in the UK.

  • Use Many Times: The Bet Boost can be used three times per day (1x football acca, 1x football bet builder, 1x horse racing), while the Epic Boost can be used three times per week (1x football bet builder, 1x NBA bet builder and 1x NFL bet builder).

  • Maximum Stakes; For the standard William Hill Bet Boost, the maximum stake is £20 and some might think this is too low. For the Epic Boost, the limit is even lower at £5, thus reducing the potential winnings.

  • Cash Out Terms: When cashing out a bet that has been boosted, the winnings are paid out at the original price, not at the boosted odds given.

  • Sports eligibility: When using the Bet and Epic Boosts, punters can only place bets on football, horse racing, NBA and NFL. It has helped William Hill claim high positions in our rankings of the best football betting sites and the best bookies for the sport of kings, but the promotion could be expanded.
