On 19 January 2026, the UKGC introduced new rules that make casino bonuses safer and easier to understand. We inspect all promotional terms to ensure they comply with UKGC rules, which include transparent and achievable wagering requirements, fair game contribution tables, no misleading bonus wording and clear expiry times. Choosing a trustworthy online casino requires more than simply checking whether a site holds a UKGC licence. As part of our February 2026 testing cycle, we reviewed the bonus terms of 22 UKGC-licensed casinos after the new rules came into effect.
