However, we award extra points to sportsbooks that cover niche markets like esports and virtual sports, which are both increasing in popularity in the UK. It’s rare to find one sportsbook with the best odds for every event, but sites like Bet365 and Betway are commonly legal sports betting sites at the top of the list. One of the most fundamental aspects of any online sportsbook is the odds available. The team at British Gambler is committed to bringing you the best and most rewarding betting opportunities, which is why this page introduces you to the top-rated betting sites.

For the biggest events, this is usually daily price boosts, giving you more value on selected players. Another real positive I like here is the value when it comes to the odds on offer. These are often strong, sometimes the very best on the market, the odds compilers at Spreadex keep things very fair for players, and it’s great to see. Onto what they offer, the welcome bonus here is excellent, with £60 in free bets given to new players, that’s a huge amount and bigger than many others on the market.

The first telltale sign of an untrustworthy site is the clear lack of licencing and regulation. Above all, you should never deposit real money to sites of this kind, regardless of how attractive their initial bonus funds or football markets appear. Some bookies have a huge range of sports markets, while others keep it simple. Luckily for some of us, we get the choice between quantity and quality. For that reason, the key to getting what you want is to compare odds and markets to find a compatible place to wager.

The live in-play section of the All British Sports sports betting site is always populated with different options and a number of sports are covered.

The UK betting sites includes Kwiff, which not only has a generous £30 free bets offer, but also supercharges many customer bets. Roughly 80% of bettors get at least one supercharge on a monthly basis, with every wager open to the prospect of being boosted. There are also surprise bet rewards which are well worth checking out.

It’s a really easy site to navigate and one I will return to again. A new UK online bookmaker for 2023 so not one I’m hugely familiar with. However, at first glance, I was impressed with the layout of the BetMGM site. The gold and black colour theme is a nice backdrop to the great variety of sports markets available to customers. I particularly like the inclusion of smaller sports that are native to specific countries – as an example, bandy is not hugely well known outside of Scandinavia. The sports homepage provides a wealth of information, including suggestions for trending bets and an outline of how to read betting odds.

Like union, the best bets to place at leading betting sites include handicaps, match winners, try bets, and over/unders. We love exploring the betting options available at new sports betting sites. One thing we have noticed is that they often focus on niche sports, Esports, US events as well as political betting and entertainment markets. There may also be a larger emphasis on virtual sports at new UK bookies, which is great if you like them.

In that case, this is a great pick, especially for newer players looking to combine media and sports betting in one experience.
