The Importance of a Bookmakers Blacklist

The list of betting sites in the UK almost appears to be endless, and new betting sites are constantly being added to it as well. Therefore, as it can even be difficult for us to stay on top of the developments, inexperienced punters do not stand much of a chance. This is where our bookmakers blacklist comes in, hoping to provide you with a fundamental benchmark in your betting ventures.

Although some sites may offer enticing welcome offers and promotions, it is important to dig deeper and investigate the site's general practices. In our reviews, we place a great amount of focus on factors such as registration, identify verification and customer precedents. All in an attempt to gather the most comprehensive picture of a site, which can suffer from serious faults despite good offers. You can read more about how we rate betting sites here.

Our reviews are thus the foundation of the bookmakers blacklist, ensuring that the latter is both reliable and accurate.

Why You Should Avoid Certain Bookmakers

Unfortunately, there are far too many examples of betting sites with poor practices in the UK, with especially new sites being culprits of this. These practices can involve anything from unjustified account suspensions to withholding of winnings. Another big issue has been a lack of social responsibility, with even the top UK bookmakers allowing customers to bet way beyond their means before taking action.

In short, it is important for new customers to carry out due diligence on the site in question, even though that can sometimes be difficult. Our bookmakers blacklist will hopefully help with this and as always, you can also read our review of the site in question. Not all sites are avoid-worthy, of course, but it is always good to find out more about a site before signing up regardless.

Just as identifying poor bookmakers is not always easy, that can also be the case for finding the best ones. Fortunately for UK punters, there are indeed several good bookmakers on the market. Below, we have picked out a few operators that stand out from the rest, and which certainly are worth giving a go if you have not tried them already.
