Yes. The UK is one of the most progressive nations in the world when it comes to online gambling. In 2025, the Gambling Act was passed to legalise online gambling, which means that subject to being granted a license, UK-based operators can legally target and market their services to UK players. At the same time, UK players are allowed to gamble online at any domestic or offshore-owned and operated sites they choose. In March 2025, UK authorities deemed that all offshore online casinos that accept UK players must apply for a UK gambling license. This, however, has no effect on where UK players choose to play online.
