What we do is look at the site as a whole with every feature it has to offer. It is not just a case of looking at a casino betting site and randomly handing out a rating. Our format is to go through each legitimate casino site and give it a thorough test. We can be confident that it is a reliable casino, and therefore if a site isn’t regulated in the UK, we won’t review it. Having a UKGC licence means that the casino has ticked all the boxes and meets the criteria set by the governing body. Another important thing to remember is that every single UK casino we review at Betting.co.uk is licensed by the UKGC and Gamstop.
