What should you look for when choosing free bets?

Whether you found a new bookie that you’d love to see us add, or you have a burning question for our team of experts, we want to know all about it. 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 – some betting sites have plenty of sports, but only a handful of ways to bet on them bet new customer offers betting app no deposit – poor market selection. Or..

Fantastic for a Football Bet– talkSPORT BET

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! Existing customer bonuses are just as important in our quest to provide you with the most value. Many mid-tier betting sites stop engaging the player after they've claimed the sign-up offer. What makes a bookie stand out are the various bonuses and promotions you can claim time after time, weeks down the road. 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.

Betway - Strong Alternative

So we make sure to find these valuable offers that you can claim even if you're already a registered customer. We have thoroughly tested and deposited with the top 20 betting sites of all time listed below. When it comes to the other couple of hundred betting sites, while we do look at what features are available, as well as what the user experience feels like, we don’t always deposit and play with every single bookmaker – though it still happens. We believe our time is better utilised finding value and deals for you! There are several hundred licensed bookmakers in the UK – a lot to go through and sometimes you just need a reliable set of bookies. The bookie hosts both a regular sportsbook and a betting exchange, making it a versatile and valuable tool for any punter.

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.

Pros of using a betting site that excels in their new customer offering

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. They're well-known for their football and horse racing markets and promotions, and are ideal for most punters' needs.

• Bet £15 Get £15 Free Bet plus £15 casino bonus
• Free Bet if your first NBA bet is on the moneyline
• Refund up to £20 in cash for a losing first Formula 1 bet
• Loyalty points multiplier for your first month
• Free Bet for using a specific payment method first time

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. 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.

Choosing the Right Betting Site

We put together a table listing all sister betting sites with sign-up offers to show which betting companies restrict you to only one welcome bonus per player and which companies let you claim every welcome bonus from every betting site they operate. We also listed all casino sister sites to cover you on that front too – now you can see how many casino bonuses you can claim per betting licence. Since its inception in 2009, BookiesBonuses's sole purpose has been to help punters find the best betting sites for their needs.

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. In addition, the bookie offers many ways to get in touch with them from live chat, email, phone call, to Facebook and X. Betano is one of the most modern-looking betting sites in the UK at this time. The bookie offers a sleek sportsbook with high speeds on both desktop and mobile, as well as superb mobile apps for iOS and Android.
