Why is it so important to choose the right bookmaker?

The bookmaker is the “partner in crime” for your entire sports betting career. He is the one who supplies you with odds for your wildest bets, from who wins elections to how many yellow cards a certain player will have over the course of a season.

The relationship with your bookmaker is significant for your betting results. As always, little things always add up: a sub-par bonus here, slightly higher odds there, and a broker can quickly find itself removed from the top spots of anyone’s mind.

How to choose the best bookmaker for betting on sports?

When choosing a betting site, there are many things you should consider. We’ve made a list of all these factors, and also a small list of brokers who we consider are the best in the UK sports betting business at this moment in time. The factors we’ve measured are:

– The variety of sports they present. Simply put, the more the better. We expect each top bookmaker to offer its customers more than enough sports to choose from.

– The quality of their bonuses. Sub-par bonuses simply don’t cut it in today’s market. A top bookmaker should have a good selection of free bets and sign up bonuses that cater to all player’s needs, regardless of play style and systems used.

– Customer support and money management. Versatility, ease of access and quickness to respond are the things we’re looking at here.

– Website and app quality. Any betting enthusiast will spend a good amount of hours using the website and the mobile app a bookmaker provides. That website should be easy to use, have great design and be easy to navigate.

– Licensing and popularity. We are firm believes that if a bookmaker has millions of customers, they can’t all be wrong – especially if we’re talking about a licensed bookmaker.

A few examples of new online bookmakers

32Red Sport – Companies which own casinos and open sportsbooks additionally are not typically well-seen, but 32Red is one of the few exceptions – especially since they’ve been around for quite some time. All this experience easily translates in a great website, awesome customer support and very easy-to-use apps, all added to a bonus scheme which competes with the best in the business. Currently, 32Red’s sign-up bonuses are second to none in the UK market.

Mr Green is another example of a company who moved from the casino gambling business into sports betting with great success. This success game mostly due to the fact that they stuck to what they knew best: creating great websites and customer interfaces, having good, quick customer support and giving their clients bonuses on an almost weekly basis. These things keep betting enthusiasts on their toes, not to miss the next big offer – and keep a bookmaker close to the top.

ComeOn are a great example of an up-and-coming bookmaker. Sure, odds might be 0,01 – 0,02 off for certain events, since they don’t currently trade the same volume of bets as other powerhouses, but when you have great bonuses, 24/7 customer support, and one of the best betting apps on the market, do you really care? Convenience should come with a price, which ComeOn are more than willing to pay.

Most popular sports for betting online

Not all sports are created equal either. We already mentioned that football is the most popular sport when it comes to betting, and for good reason, too. It is currently the most popular, widely-viewed and played sport on the planet, with billions of fans around the globe.

Other games simply cannot threaten first place, but are more than happy to compete for other sectors of the market. Interestingly enough, although football is popular around the globe, other sports are more geographically-dependant.

For example, although the British love their football betting dearly, they are very passionate about horse racing betting too. Basketball and ice hockey, while very popular in other countries (such as the U.S, Spain or Canada) simply have no success in the U.K.

Tennis is another very popular sport, but is very tied to a nation’s success in it. Serbian’s passions for the sport grew immensely with Djokovic’s success, while Nadal is a national hero in Spain, who also brings important gains for the betting industry.

Other more niche sports such as cycling have their fair share of fans, while E-sports are also making a good case recently. Games like League of Legends, Dota 2 and StarCraft 2 have millions of fans around the world, who all want to be able to place a bet on their favorite team.

Of course, not all sports are equal in the betting world – the undisputed victor is football (soccer, for our U.S. readers), which controls more than half of the worldwide funds when it comes to betting.

Other sports such as tennis, cricket, basketball, horse racing or E-sports enjoy brief spells of popularity in different nations and areas, as well as times. But one factor will always remain important, regardless of the sport we’re researching: the bookmaker.


To sum up, there are more than enough bookmakers on the UK betting scene to cater to your needs and passions, regardless of the sport you’re passionate about. These betting websites range from traditional ones who have been around for tens of years to up-and-coming stars, all with their pros and cons. It’s vital to figure out what your betting objectives are and what you want to achieve through sports betting before picking a bookmaker. If you nail this decision, you’re in for quite good times.
