How We Rate Casinos

At Boss Services, we've developed a comprehensive methodology to evaluate non-Gamstop casinos operating in 2026. Our ratings help UK players find safe, fair, and enjoyable gaming experiences. Below is how we assess each casino across seven key criteria.

1. Licensing & Regulation
