What Makes a Casino Safe for UK Players?
In the United Kingdom, all online gambling sites must hold a licence issued by the UK Gambling Commission (UKGC) — the government body responsible for regulating commercial gambling. Without this licence, an operator cannot legally accept wagers from UK residents.
UKGC-licensed sites are legally required to offer responsible gambling tools including deposit limits, self-exclusion options, and reality checks. They must also segregate player funds, use fair and independently-audited RNG software, and prominently display problem gambling support information.
Our 8-Point Review Checklist
