Best UK Betting Sites: Expert Tested & Top Rated (2025)

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 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.

Best Features: Having named bet365 as the best overall bookie, we felt it was best to opt for a different bookie in this category: Virgin Bet. The brand is well-known in the UK, for obvious reasons, and the sportsbook is provided by Kambi. There are some great promotions for football, including the early payout (two goals up).

Biggest Negatives: Virgin Bet remains a relatively new site, so there are still some things to improve. The betting margins could be slightly better, while the minimum deposit for PayPal is quite high. We are clutching a bit at straws, though, as the bookie is one we like and use fairly frequently.

Our View: If you are tired of the mainstream bookies, even if they are all very good, it is definitely worth checking out Virgin Bet. The bookie has a lot to offer, from the fantastic betting app to the early payout promotion, and there is a pretty decent welcome offer as well. It does not get much better than that.

Best Features: Betfred speaks for itself, in many ways, but it's an easy choice for this category thanks to the consistency in the offers. While the offer has changed a few times in the last few years, the sports bonus amount has remained around £40-60, which is great value for any punters in the UK. The rest, as said, does indeed speak for itself.

Biggest Negatives: We do not really see any downside to the welcome offers at Betfred, whether that be the sports, casino, bingo and so on. Even some of the big bookies will add wagering requirements for the casino offers, but that is not the case at Betfred so we only have praise on the welcome bonus front.

Our View: If we disregard the generous welcome offers for a while, there are other good things to say about Betfred. The app is easy to use and gives you everything you need, withdrawals are very quick, and the sportsbook is usually very comprehensive. Improvements can always be made, but there is a lot to like.

Best Features: Based on the Smarkets betting exchange, SBK might not be the oldest bookie on the block but it has established itself 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 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 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 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, with some important markets missing. Furthermore, the betting margins are not exactly fantastic unless your bet gets Kwiffed, or Supercharged, as shown in the image above.

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 Features: BetTom launched in the summer of 2025 and has enjoyed a lot of success already. The partnership with EveryMatrix means there is a comprehensive sportsbook on offer, with low betting margins, while fast withdrawals are also offered (we got our money after just a few minutes).

Biggest Negatives: Since BetTom is such a new site, there are obviously some things that could be done better. For example, the design is not our favourite, while only a few payment methods are accepted by the bookie. There are no glaring issues, though, which is good and means 'easy' improvements can be made.

Our View: We often see new betting sites launching with incomplete products, but this is not the case with BetTom. If anything, the bookie has shown that it intends to compete with the rest of the newcomers and potentially even some of the top dogs. For the latter to happen, however, some improvements will be needed.

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.

Best Features: These days, almost all punters in the UK prioritise good payment method options. E-wallets have grown tremendously in popularity and the introduction of Instant Bank Transfer has changed the way we look at fast withdrawals. On these fronts, William Hill shines with low minimum amounts and many options to choose between.

Biggest Negatives: For the e-wallets, William Hill has a minimum deposit of £10 and that could certainly be lowered. Skrill and Neteller users can withdraw £5, but the PayPal limit is still set at £10 for withdrawals. This will not be a problem for most punters, but it is still worth keeping in mind.

Our View: William Hill is one of the best bookmakers, there is no doubt about it, and having your winnings within just a few minutes (via Instant Bank Transfer) is a huge perk. Anyone who wants a solid bookmaker with a good user experience will likely not be disappointed by the blue and yellow-themed bookie.
