UK Gambling Commission
It was in 2005 when the UK Gambling Commission was first established and its full powers came into effect in 2007. This body is responsible for overseeing remote gambling, as well as certain areas of the land based establishments within the United Kingdom.
Any casino looking to obtain a license from this body will need to first pay the licensing fees, as well as taxes. With this sort of license, the casino is then able to operate within the borders of the UK. Those casinos that are based outside of the UK are still able to advertise to the UK market if they have been whitelisted by the UK Gambling Commission. With this title, they are considered to be licensed through the commission and they are also considered legitimate within the UK.
It was in 2014 when the power of the UK Gambling Commission was greatly expanded. From this point, all casinos operating within the UK had to receive a license within this area, including each segment of the casino (games, sports betting, poker etc.). Strict taxation was also imposed on the casinos.
