Below you can find the best tennis betting sites in Bojoko’s opinion. You can find our ranking factors in more detail below, but without further ado, our top 2 tennis bookmakers for UK players!
William Hill is one of the best choices of a bookie for UK players in general, and with tennis being such a popular sport here it’s of course heavily featured. This means that great odds and wide betting markets can always be found for tennis at William Hill.
In addition to being one of the best places to bet on tennis in general, the special tennis offers the bookie has are almost unmatched in the industry. With live streams also being available for many top-quality tournaments, there isn’t much bad to be said!
For new players, by depositing £10 and betting the same amount with minimum odds of 1/2 you will receive 2 x £15 free bets! Enjoy our extensive William Hill betting review to find out more.
➕ Pros: £30 free bet sign-up offer, Top quality markets, live streams, great tennis offers
➖ Cons: Not the greatest user interface
LeoVegas is not a UK bookie, but the Nordic betting giants are a great choice for UK players’ tennis bets thanks to the great odds provided on the site with price boosts being often available for the most interesting tournaments. In addition to this, Leo is one of the best mobile bookies out there.
This means that when you're on the go, Leo's award-winning mobile app or browser version is probably the best choice for your mobile bets. Markets are available on almost all smaller tennis tournaments as well, so with this lion you're in good hands.
At Leo new players are treated to a 100% profit boost on their first in-play bet on a mobile device up to £100! This bonus can be received by choosing Sports Welcome Bonus when making your first deposit, which must be at least £10.

There are of course some other things to check out when choosing betting sites for tennis, such as style, mobile and responsible gambling functions.

The best tennis tournaments to bet on are, of course, the biggest and most followed ones, as they have the most betting markets available on them. The biggest tennis tournaments each year are the Grand Slams, of which there are four each year.
The Australian, French and US Open and the legendary Wimbledon gather millions of viewers from around the world, while the Olympics’ tennis tournaments are also closely followed by most tennis fans. In addition, plenty of tennis betting odds are available for both the ATP & WTA Tours.
The second Grand Slam tournament of the season (after Australia) is the French Open, named after famed French pilot Roland Garros and his namesake stadium. Played on clay unlike any other grand slam, the undoubted king of the tournament has been Rafael Nadal, who has taken the crown 14 times, including the 2022 edition.
The fast-paced clay courts give advantage to more physical players with harder hitting shots, which you should always take into account with your bets.
Are you interested in betting on the French Open? Below you will find the early outright odds for both the men's and women's tournaments. The odds are provided by the betting site LeoVegas which offers all new players a 100% deposit bonus on opening a new account.
French open men's singles odds:
Tournament over, Novak Djokovic champion.
Enjoy the best french open odds at Leovegas »French open women's singles odds:
Tournament over, Iga Swiatek champion.
Bet french open at Leovegas »After Wimbledon, the tennis world takes a trip across the pond to the United States for the US Open. Held in Queens, New York, the USTA Billie Jean King National Tennis Center has been home to some legendary tournaments and provides fantastic betting opportunities every year.
Below you will find the latest betting odds for the USA Open tennis tournament that will take place in 2023. It is worth noting that all of the odds listed below are provided by BoyleSports, which is one of the reliable tennis bookmakers for UK punters.
If you are a newly-registered player at BoyleSports and put down a deposit of only £10, you will be rewarded with £20 in free bet tokens credited to your account.
US open men's singles odds:
US open women's singles odds:
The Wimbledon tennis tournament is long-awaited every year, and the 2023 edition of grass mastery will continue the Grand Slam season with its showpiece event.
Being the third major tournament of the year and the only one to be played on grass, the most famous tournament in tennis is the highlight of the year for players and bettors who know what happens when you play on the most classic court of the sport.
The men's tournament last year saw little drama when Novak Djokovic, who has a record of 7 title wins on the Wimbledon grass took home yet another victory to add to his tally over Nick Kyrgios. There aren't many realistic challengers for the Serbian this year, but Carlos Alcaraz is in with the best shot.
The bookies are also favouring Daniil Medvedev and Matteo Berrettini to be within a shout. Check out the best odds on the tournament offered by betting site 21Luckybet, claim the brand's £40 free bet offer and place your bets.
Odds updated: 27 July 2024
Tournament over, Carlos Alcaraz is the Wimbledon Champion 2023.
Bet on Wimbledon at 21luckybet »Wimbledon women's singles odds:
Iga Świątek is the favourite to win the women's singles in Wimbledon. She has emerged as the number-one favourite for almost all tennis tournaments she ends up competing in, but on grass at Wimbledon the competition is much tougher for her away from her preferred surface of clay.
Odds updated: 27 July 2024
Tournament over, Marketa Vondrousova is the women's Wimbledon Champion 2023.
Enjoy the best Wimbledon odds at 21luckybet »The ATP Tour is the premier competition for male tennis players, going on across the year. If you really want to get into tennis bets, the ATP Tour will be your bread and butter where you can make the most consistent profits. Unlike at the Grand Slams, at ATP tournaments all of the best players in the world won’t necessarily be playing.
You must always know the players competing at an ATP tournament, along with of course their form, how important the tournament is to them, possible injury issues etc. before choosing your bets.
The WTA Tour is the womens’ equivalent of the ATP Tour, with the tournaments often going hand in hand in terms of schedule. All the same betting rules mentioned above apply to the WTA tournaments as well, so there isn’t much to add here.
One thing that you should always remember when betting on the WTA and women's tennis in general is that the matches are always settled over a maximum of three sets.
If you want to place a tennis bet, there are many different choices to choose from in a tournament or for any given match. The amount of betting markets available of course depends heavily on the size of the bookie, but you can find the following bets nearly always at the best UK betting sites:
In addition to these, there are always some player and tournament specials to be found, such as which player will make it further in the tournament etc. These however aren’t usually the best bets to choose, as advantages in them are hard to find for a bettor.
Your tennis betting strategy should always be based on statistics more than your heart. By using the tips below you can get started with tennis betting the in the easiest way.
In addition to these tips, you should also know the most important statistics for evaluating how a match will go. These four are:
By analyzing these you can usually get a good idea of how a matchup will end up, especially when it comes to the amount of winners a player hits and a player's amount of points they win with their second serve.
Second serve efficiency is particularly important to know, and star players who don't excel in this aspect are particularly at risk for upsets if their first serve is having problems.
In many sports, bettors tend to bet more on the favourites or big names with a brand. Big teams like FC Barcelona in football or the Los Angeles Lakers in basketball get a lot of turnover in betting every single time. But in tennis, it tends to go the other way. Academic studies have shown that tennis bettors tend to lean more toward the underdogs. This phenomenon is known as the favourite longshot bias.
The bigger the tournament, the bigger this bias seems to be. Tennis bets on the underdog seem to be particularly common in the biggest tournaments like Grand Slams and the Olympics, which may be due to less experienced tennis bettors placing more bets.
According to a 2015 University of Navarre study, bias on the underdog is especially prevalent in tennis matches in the biggest tournaments, in later round matches of tournaments, and between lower-ranked players. Other studies have also shown this effect on tennis bets.
Knowing this can already give you an advantage over many other bettors. Especially when betting on bigger tournaments, according to the studies, there should be more value to be found on the favourites. So when the other stats, injuries and the bracket is good, bet more on the favourites.
Tennis is a classic and one sport that truly captures the hearts of British punters. There are plenty of other options when it comes to betting, and they may be interesting to you when good tennis bets aren't available.
You may want to take a look at the following:
