Casino sister sites are online casinos that share the same parent operator, gaming licence infrastructure or software platform. In the UK, each sister site casino must individually hold a UKGC licence — meaning they all meet identical standards for responsible gambling, fair play and player fund protection.
The UK market is dominated by major operator groups: GVC Holdings, Flutter Entertainment, Kindred Group and 888 Holdings. Each group operates dozens of sister casino sites with different branding but shared game libraries and payment processors. This means finding a sister site casino UK is often as simple as exploring a network you already trust.
Sister sites casino UK also share GamStop self-exclusion. If you register with GamStop, your exclusion automatically applies to every UKGC-licensed sister site casino, providing comprehensive protection across entire operator networks.
