The Best Betting Sites for Bet Builders in the UK 2025

What is a Bet Builder?

Before revealing my best Bet Builders sites, I want to briefly explain what a Bet Builder is, how it works, and why it has become one of the best ways to gamble on football and sports.

In the past, football bettors could only bet on a single market in a football match, such as the winner or the first scorer. Combining two or more picks in a fixture was known as a related bet and was banned. But the Bet Builder changed all that.

Now, you can add multiple markets from one fixture to your bet slip, creating a same-game multiple. Pick the winner, total goals, first scorer, handicap, highest scoring half, half-time/full-time, bookies, and other favourites. You now have multiple reasons to cheer in a match, covering everything from tackles and assists to goals.

How We Rank the Best Bet Builder Sites

How did we find the best Bet Builder sites in such a competitive market? I studied the market in great detail, drawing on my extensive experience. To feature on this page, a bookmaker had to impress me in each of the following areas.

• Range of available markets: More ways to bet means more ways to win, and I selected bookmakers with a wide range of stats-based markets. Each firm featured in this review offers betting on popular markets, such as anytime scorer, but also covers shots on target, cards, tackles, and corners.
• Odds quality: Offering competitive odds is just as important as providing multiple markets. The bookmakers listed on this page are often market top price on the teams, competitions, and bets you love the most. Higher odds mean more cash in your pocket when you pick a winner.
