Best Tennis Betting Sites in the UK for 2026

A year-round sport with a British summer peak

Tennis is one of the few sports that runs almost all year, from the Australian Open in January to the ATP and WTA Finals in November. For UK punters the calendar peaks in June and July, when the grass-court swing at Queen's, Eastbourne and Wimbledon dominates the schedule and British players attract heavy interest.

The challenge for a tennis sportsbook is volume. On a typical weekday there are dozens of ATP, WTA, Challenger and ITF matches, often running at the same time across several continents. A strong tennis site needs to price them all, keep in-play odds moving point by point and settle retirements and walkovers clearly.

bet365 and Unibet set the standard

bet365 tops this ranking with the deepest tennis offering we found among UK-licensed bookmakers. It covers matches well into the Challenger tour, offers set and game handicaps, total games and next-game markets in play, and streams a large share of matches to customers with a funded account. Its 9.4 odds rating matters here, because tennis margins vary widely between operators.

Unibet is second and is a real alternative rather than a distant runner-up. Its tennis coverage is excellent, the app scores 8.8, and its odds rating of 8.9 keeps it competitive on main-tour matches. BetMGM, in third, is strong on Grand Slams and ATP 1000 events but thinner on lower-tier tournaments, while LeoVegas earns its place with the best mobile app on our list, which is useful when you are following a match point by point on your phone.

Tennis markets worth understanding

Match winner is the simplest bet, but heavy favourites often offer little value. Experienced tennis bettors tend to look at other markets:

• Set betting: picking the exact score, such as 2-1 in a best-of-three match, pays more than the match result.
• Game handicaps: useful when a favourite is expected to win comfortably.
• Total games: a way to bet on how competitive a match will be without picking the winner.
• In-play next game or next set: fast-moving markets that reward close attention but can also encourage impulsive betting.

Retirement rules and surfaces

Bookmakers handle retirements differently. Some void the bet if a player retires before the match finishes, while others settle on the player who advances once a set has been completed. Check the rules on each site before you place a bet, especially early in the clay or grass seasons when injuries are more common.

Surface form matters more in tennis than in most sports. A player with a big serve can thrive at Wimbledon and struggle on clay at Roland-Garros, so look at results on the same surface rather than overall ranking alone. Tennis in-play can be intense, with a new market every few minutes, so set a session time limit in your account if you tend to follow long matches.
