We’ve also published new coverage of the growing debate around affordability checks. This remains one of the biggest issues facing UK casino players and operators, particularly as the industry continues to balance safer gambling requirements with a smooth customer experience. A licence means the operator has met requirements on security, fund protection and responsible gambling, and that you are covered by UK law if something goes wrong. Unlicensed casinos offer none of that protection, whatever they claim on the site.

Since January 2026 the UKGC caps wagering at 10x for all UK-licensed operators. This is a significant improvement from the 30x–50x requirements that were previously common. In addition, mixed-product bonuses (e.g. casino and sports bonuses in one offer) are no longer permitted under the new rules. Casino bonuses are legal in the UK when they are offered by operators that are licensed and regulated by the UK Gambling Commission. All of our recommended casinos are fully licensed, and we make sure their offers comply with UK laws and regulations.
