At Compare.bet our aim is simple – to provide unrivalled comparison of online gambling providers, from sports betting to casino, bingo to eSports and lots more. Our editorial team has conducted detailed research of the market to bring you our specially curated top-list of UK-licensed gambling operators. There are hundreds of places to gamble online, but we’ve distilled that long list down to only the best of the best.

We’re currently focusing on sports betting, and have put together a fantastic list of bookies for you to test out. You’ll find plenty of info on their free bets and bonuses, mobile apps, odds and markets plus much more. If you have any feedback, we’d love to hear it at [email protected]

What should I be looking for when choosing a bookmaker?

There are a number of things to consider. Many people automatically think about free bets and bonuses – and with good reason. You’ll often find offers like ‘bet £5 get £10 free’, or ‘100% deposit match up to £50’. While they will usually have a number of terms and restrictions applied, they certainly boost the incentive for getting started with one bookie over another. You’ll also want to think about range of markets, availability of live betting, bonus features like cashout or live streaming, and mobile friendliness – all of which are covered in our in-depth betting site reviews.
