some have high wagering requirements, which means you likely won't keep much profit from your welcome bonus. It is our duty to inform you of such caveats, so you always make an educated choice!

BOYLE Sports is another flagship bookmaker that has been around since '82. The daily extra places for horse racing are just the icing on the cake for BOYLE – there are promotions running for most of the popular sports. Livestreaming, clean website design, intuitive navigation and responsive customer support are all things that come to mind, when talking about the bookie. Betfair has been a very popular and respected bookmaker for over two decades. The bookie hosts both a regular sportsbook and a betting exchange, making it a versatile and valuable tool for any punter.

11. William Hill

I like the variety of football betting markets, and the plethora of payment methods with low deposit limits. Betfred is an age-old bookmaker with tonnes of experience in the UK market. They're well-known for their football and horse racing markets and promotions, and are ideal for most punters' needs. While some variety in the promotions department wouldn't hurt, Betfred absolutely is a solid choice of a betting site. Sky Bet is a powerhouse when it comes to livestreaming licenses, sponsorships and everything in between.

8. Grosvenor

I would recommend Sky Bet to punters looking for livestreaming and in-play betting on horse racing, football, basketball and boxing. Sky have really put their best foot forward when it comes to market variety and competitive odds. Their promotions are nothing to sniff at either, especially their AccaFreeze feature. Parimatch's presence is not limited to the UK, as the bookmaker is reputable in other countries as well. Being the official betting partner of Nottingham Forest and Leicester City has further affirmed their legitimacy and shown how seriously they take the betting. Betano is one of the most modern-looking betting sites in the UK at this time.

• Most offers require a minimum deposit and a qualifying bet
• Free bet tokens are usually credited within 24 hours
• Wagering requirements and odds restrictions often apply
• Always check the promotion's full terms and conditions
• Some offers are sport-specific, like football or horse racing

The bookie offers a sleek sportsbook with high speeds on both desktop and mobile, as well as superb mobile apps for iOS and Android. The sports selection and the available odds thereof are nothing short of brilliant, with corners, cards and Asian handicaps available for matches left and right.

What really takes the cake, though, are thought-out navigation elements – it feels like everything is easy to find, while features like the bet builder, accumulator and cash out are a click (or tap) away. Not long after BetMGM launched in the UK it gained traction and became a hit with punters. With plenty of experience from the States, BetMGM is an established brand, with a strong welcome offer, good ongoing player promotions and very competitive odds.

No matter what you're looking to bet on and which betting site you sign up with, we strive to help you find the best value possible through promotions, betting offers, competitive odds and boosts thereof. BookiesBonuses was launched by two guys in 2009, as a side project to their studies and other commitments.

The two founders, Eskil and Jens, are still involved, but they are no longer the main writers for the site. As BookiesBonuses grew into a seed for more projects over the years, they had to take on oversight roles. The founders had a background in poker, but were also interested in sports betting. With time they realized there was no service for an easy comparison of welcome offers online. Initially, the site was really just a product for themselves and their friends, aggregating the offers in order to compare. As with all good things, there are also negatives and in the case of BetMGM, that would have to be their basic bet builder, which could use an update. With over 30 sports to bet on, high odds and good customer support, MGM is a solid contender for the top 5.

Grand National Free Bets & Betting Offers for New Customers

Over the coming years, more people found BookiesBonuses and appreciated the service it provided when looking for a good bookmaker. It became a go-to product for a lot of British punters. In 2012, it got its first major facelift, as the two founders were joined by a developer. In 2016, the trio decided to make the side project their full-time job and launched several similar sites in different countries. Also, at this time they realized they needed more hands on deck and recruited a new project leader for BookiesBonuses.

That is when it got its second facelift. Since English is an international language, the website also garnered interest from many other nations. To cater to these punters, information about bookmakers in these countries was also added to the site. Today, we cover 18 countries outside of the UK. The market has changed over the years, but our goal of helping punters find a betting site for their needs remains.

Can I use free bets on any sport?

This is why we constantly check on our email, so you can reach out at any point of your betting journey. Straight talk – if a bookmaker sucks or has poor features, we'll tell you out about it. For example – bet bonus sign up no deposit some betting sites have plenty of sports, but only a handful of ways to bet on them – poor market selection. Or.. BetVictor is another great bookmaker that has made its name in the UK. Widely recognised by punters for their football markets and their frequent promotions for a raft of sports, BetVictor doesn't disappoint. In fact, it is worth mentioning that BetVictor and Parimatch share a license, and are operated by BV Gaming Limited, so any new updates and features will likely be available on both sites.

William Hill is typically among one of the first betting sites UK punters sign up to, largely due to its popularity.

And that popularity is justified with the consistency they've displayed throughout the years. That consistency has manifested in the form of reliable customer support, always competitive odds, constantly featuring boosted odds on popular events and last but not least, always trying to serve the players first. Betway is a very popular bookmaker across Europe.

They've achieved this fame by being really good at what they do and by being official sponsors to different club (currently West Ham United in the EPL). Apart from the usual major sports, Betway leans heavily into esports and is one of the best in the business in that category. PaddyPower ranks highly in the hearts of passionate punters, as the bookie combines their experience with constant innovation. Paddy is known to offer a variety of promotions to new and existing customers alike. Horse racing is definitely a strong suit of the bookie, as the numerous markets and options go to prove. PaddyPower also found a way to keep their community engaged with different features, such as 'Beat The Drop' or unique boosted odds.
