Independent online casinos include Fabulous Bingo, William Hill, Titan Bet, Marathon Bet, NetBet, Super Casino, and Eurobet.
At Sister-Sites.co.uk, we've reviewed 108 independent casinos from operators like VF2011, Universe Entertainment Services and Marathonbet Spain. Not all of the gambling firms hold a valid UK licence, so please verify their legal status before signing up. If in doubt, choose one of our recommended online casinos for December 2025.
Some operators focus on a single website rather than operating a range of sister sites. This approach has pros and cons, and we don't recommend against registering with an independent online casino. Below, you will find a list of all independent operators of online casinos, some of which hold a UK license.

Some operators focus their energy on a single brand rather than launching various gambling websites simultaneously. Such online casinos without sister sites are often referred to as independent.
Whether an independent casino is safe depends on many factors, especially the licence status of its operator. Casumo is a standalone online casino and probably one of the safest in the United Kingdom. It's important always to check whether the firm behind the website holds a valid gambling permit issued by the UK's Gambling Commission.
Independent online casinos enjoy the full focus of their operators, making it easy to iron out potential issues as they appear. However, this benefit is only theoretically true since sister site operators do not reinvent the wheel for each brand. Instead, they use a blueprint that all websites share, making them easy to maintain.
The biggest drawback of standalone gambling websites is the lack of sister sites. If you like the casino or bingo website where you're a customer, you cannot jump to one of its related sites and grab a new bonus. As such, you may feel stuck after a while.
