This page matters more on this site than on most. The casinos reviewed here sit outside GamStop, which is the main brake the British system provides, so the responsibility for limits sits with you.
If you are looking for a site outside GamStop because GamStop is stopping you from gambling, that is the clearest possible sign to stop and talk to someone. The helpline below is free and you do not need to be in crisis to use it.
National Gambling Helpline — 0808 8020 133. Free, confidential and open at any hour of any day, run by GamCare. There is a live chat option at gamcare.org.uk.
BeGambleAware — begambleaware.org has a self-assessment tool and a directory of free local treatment across England Scotland and Wales.
Gordon Moody — residential and online treatment for severe gambling addiction.
GamAnon — support for family members and friends, who are frequently affected as much as the person gambling.
GamStop does not cover the casinos reviewed on this site. Device-level blocking does.
BetBlocker is free, covers tens of thousands of gambling sites and can be set for a fixed period you cannot undo. Gamban is paid and works across phone tablet and desktop. Either will block sites GamStop cannot reach, which is exactly the gap that matters here.
Your bank may also help. Most UK banks now offer a gambling block on card transactions which you can switch on in the app, and some enforce a cooling-off period before it can be switched off again.
Gambling for longer than you meant to. Going back to win back what you lost. Borrowing money or selling something to fund it. Hiding how much you gamble from people close to you. Feeling anxious or low when you are not gambling. Finding it has started to crowd out things you used to care about.
Any one of those is a reason to pause. Several together is a reason to ring the helpline today rather than at some point.
Decide what you are prepared to lose before you deposit and deposit only that. Keep gambling money in a separate account from money that has a job. Set a time limit as well as a money limit because sessions stretch. Never gamble to solve a money problem, and never gamble while drinking or upset.
Use the operator's own deposit limit and cool-off tools where they exist. On sites outside the UK system those tools are usually thinner than the UKGC versions, which is another reason to set your own limit rather than relying on the site to set one for you.
