Existing customers are also well-catered for, with five bonus spins and 10% cashback available during the weekends.

One red flag I noted against LeoVegas in testing was their slow customer support. I had some technical issues verifying my identity which took days to resolve due to slow response times and frustratingly inefficient technology.

Remember to always read the terms and conditions before playing, as UK players often forget. You should be looking out for wagering requirements, how easy the wager contribution is to understand, as well as minimum deposits and withdrawal restrictions. Live chat, long opening hours and a short queue are all things that should come as standard at an online casino. We also consider the sheer quality of the service, as well as the accessibility. When it comes to new casino sites in particular, we have noticed that the customer service tends to be best at a new casino the first year after launch.
The deposits are processed quickly, with a flexible minimum limit of £10, plus the withdrawals are secure and hassle-free. There are a large number of pay by mobile casinos available in the UK which accept deposits made using a bettor’s phone tariff. The payment is added to a bettor’s phone bill or comes off their pay as you go balance. The biggest issue with this payment method is that it’s deposit only, with withdrawals not possible.
Apps often give quicker access, push alerts, and sometimes app-only promos; browsers are fine if you prefer not to install anything.

A casino earns a high score for its promos if new players can sign up with both a £50+ deposit match and large number of free spins, especially if these include no deposit offers. After that, we check if there’s daily and weekly bonuses up for grabs, and a VIP or loyalty scheme offering regular players the chance to claim extra rewards. Almost all casinos non GamStop slots have sign-up promos offered as an incentive to new players to create an account and make your first deposit. Welcome bonuses tend to be among the most generous rewards up for grabs at a casino, and normally involve a combination of a deposit match, free spins and/or cashback.
