How We Rate Casinos
At CDL Sites, we've developed a comprehensive methodology to evaluate and rank the best betting sites in the UK. Our expert reviewers assess each casino across eight key criteria to ensure fair, transparent ratings that help you find the perfect platform.
1. Licensing & Regulation
Player safety is our top priority. We verify that every casino holds valid licenses from recognised regulatory bodies, with preference given to:
- UK Gambling Commission (UKGC) – The gold standard for UK-based operators

- Curaçao Licensing – Established offshore jurisdiction
- Local GB Licenses – Additional UK regulatory compliance
We check licensing status, regulatory history, and player dispute handling records.
