Best Betting Sites (December 2025)

Best UK Betting Sites by Category

After rigorous tests, our experts compare and rank the best betting sites available for UK punters. Of course, picking the "best" betting site is undeniably subjective, with all UK online bookmakers on our list offering great gambling products.

Also, no one bookmaker is universally perfect for everyone, and you will only find out if it's right for you by trying it yourself. Below, we have listed the best betting sites for the most prominent sports in the UK, seeing as many punters only tend to bet on one sport. It makes sense, therefore, to choose the best bookie for the sport in question.

🏆 Best Betting Site Overall: bet365

Best Features: If there is one thing that our experts have in common, it is the love for bet365. The betting site offers everything you need and consistently stays ahead of the competition with innovative features. The most important one, in our opinion, is the bet builder tool which is miles ahead of the competition.

Biggest Negatives: The bet365 website and mobile app are very user-friendly and easy to use. However, the design can be a bit boring at times and this is something that the bookie can improve. We are clutching at straws here, though, as we genuinely feel that be365 has no weaknesses.

Our View: Bet365 is the best sports betting site in the UK because it offers a wide range of sports and markets, competitive odds, live betting and streaming, a user-friendly platform, and a number of other features and benefits. Once you try the site, you will likely never want to leave. One can also respect bet365's decision not to launch any sister sites, focusing solely on the core.

🏇 Best Horse Racing Betting: Unibet

Best Features: Unibet is truly one of the best bookies when it comes to horse racing, covering meetings from all over the world. Best Odds Guaranteed is in place for UK and Irish races, as you would expect, and the promotion Uniboost allows punters to boost the odds of a horse racing bet three times per day (!). The latter really makes the bookie and out.

Biggest Negatives: Perhaps the only downside of using Unibet for horse racing betting is the fact that Tote betting is not offered. Almost all of the top horse racing competitors offer this, such as Placepot and Quadpot, so Unibet should probably look at getting that fixed as soon as possible.

Our View: Unibet is an extremely solid bookmaker for most sports and the racing section has been given a bit more love. Promotions are not really offered for any other sports, not even football most of the time, so it is clear that the bookmaker focuses more on racing in the UK.

🔢 Highest Betting Odds: SBK

Best Features: Based on the Smarkets betting exchange, SBK is a rather new sportsbook but it has already made a strong splash in the industry thanks to market-leading odds. SBK is made for mobile and the betting app works brilliantly on all types of devices.

Biggest Negatives: The live streaming available at SBK is limited right now, with a more no-frills approach taken compared to some of the other top mobile betting sites around.

Our View: Sports fans who want to make sure they get the best possible value out of their bets really should be using SBK as its odds come from the Smarkets betting exchange and are usually the best around in our tests. The mobile app from SBK works like a dream, so it is easier and faster than ever before for users to place in-play bets.

💻 Best Live Streaming: William Hill

Best Features: William Hill is certainly one of the best bookmakers in the UK, offering great depth for almost all sports, and live streaming has been a key strength of the site for many years. Most punters will have heard of William Hill TV and the reputation is indeed warranted, with many different events to stream.

Biggest Negatives: Although the live streaming is very good, William Hill is not always the most 'flashy' bookmaker. The site design is rather dull and while there are some good promotions, one can understand why punters might opt for another bookie. After all, these days, the design and overall feel are very important.

Our View: William Hill remains a good choice for almost every sport and this is also the main strength of the site. If you are a punter who likes to bet on several different sports, William Hill could be the perfect site for you.

📱 Best Betting App: Kwiff

Best Features: Kwiff was initially launched as a mobile-only brand in 2015, but has since expanded its operations to desktop and mobile browsers. Based on the ratings, with 4.5 and 3.-5 out of five stars on the App Store and Google Play Store respectively, Kwiff has one of the best betting apps on the market. After all, you cannot argue with the experiences of other punters.

Biggest Negatives: The sportsbook at Kwiff is still a bit undeveloped compared to other betting sites in the UK. As we covered in our review of the site, there is currently no bet builder and this is something that will have to be fixed. The depth of markets is also not as impressive as the bid dogs.

Our View: Kwiff is a fun and engaging betting site thanks to the 'Kwiffed' or 'Supercharged' feature. This means that randomly, the bookie might decide to boost the odds of your placed bets, which adds an element of surprise to the betting. If you are tired of the conventional bookies, therefore, Kwiff could be worth a try.

🆕 Best New Betting Site: Lottoland

Best Features: Lottoland is not exactly known for its sportsbook, which is a relatively new section of the site, and thus some UK punters might be hesitant. However, the sportsbook is actually fairly decent and the ability to deposit just £1 could come in handy, even if it might be hard to make a profit.

Biggest Negatives: Similarly to Kwiff, the sportsbook still needs a lot of work to be considered among the best in the UK. There is a bet builder, which Lottoland deserves praise for, but the depth of markets is currently not enough. The popular e-wallets are also missing from the list of payment methods.

Our View: As often is the case with less prominent bookies, Lottoland has clearly decided to focus on one thing to gain attention, more specifically the low deposit and withdrawal amounts. And props to them, because that strategy is working! The £1 minimum deposit will surely catch the eye of many punters.

📊 Best Spread Betting Site: Spreadex

Best Features: While spread betting is complex and not suitable for beginners, Spreadex makes it straightforward to learn all about how it works and gets users up and running very quickly. The site also has a simple sportsbook so there is much more on offer here than just spread betting.

Biggest Negatives: Spread betting is not something for the faint-hearted and it is possible to lose substantial amounts of money, though Spreadex is good at helping its users to set limits in place so it is fairly easy to ensure that customers always stay in control of their betting here.

Our View: Spread betting is still seen as a fairly niche option within the UK online betting world, but Spreadex also has a solid sportsbook site so it covers a wide range of bases. There is no doubt that the popularity of spread betting is on the rise, with Spreadex well-placed to profit.
