In the UK, the entire gambling industry is regulated by the UK Gambling Commission (UKGC). It is an independent body that ensures all gambling activity takes place legally, fairly, and responsibly. The UKGC sets strict standards that casino sites must follow to receive a license; these cover everything from player protection to anti-money laundering measures. The casino regulations ensure players can trust that licensed sites are safe, transparent, and committed to fair play. It’s important to note that credit cards are banned for gambling in the UK due to concerns about responsible gaming.
