All reputable UK-licenced online casinos display their license number in their website’s footer. Therefore, the best way to tell if a casino is licensed and regulated in the UK is by clicking on the license number. If the link is valid, it should take you directly to the United Kingdom Gambling Commission–an organization that manages and grants licenses for all internet gambling sites that accept players from the UK. The UKGC is widely considered reputable and reliable by most industry experts and independent observers.
