Licensing, in plain terms
What a British licence actually gets you
Any business offering online casino games to people in Great Britain must hold an operating licence from the Gambling Commission. That is not a badge for the footer; it carries obligations that matter on the days things go wrong. Licensed operators must check your age before you play, keep customer money separate from company money to a disclosed standard, publish the terms governing your bonuses, and give you working tools to limit or stop your own play.
The licence also names addresses. Each register entry lists the web addresses the licensee may trade from — the most useful check a player can run, because if the site in your browser is missing from that list, you are not covered by the protections you assume you have. Every address in our table came from it.
Two limits, bluntly: a licence does not make a casino generous, and it does not improve the odds. Nor does it cover Northern Ireland, which has its own gambling law; the Commission licenses gambling in England, Scotland and Wales.
