GamCare — free, 24/7

Yes. Every casino on this page holds an active licence from the UK Gambling Commission. We check licence status monthly and immediately delist any operator whose licence is suspended or revoked. You can verify any casino's licence yourself at gamblingcommission.gov.uk.
We score across five areas: game selection, bonus fairness, user experience, payment speed and mobile quality. Each area gets a mark out of 10 and the overall score is a weighted average. We update scores monthly.
You must be 18 or older to gamble online in the UK. Licensed operators are required to verify your identity and age before you can deposit. Underage gambling is a criminal offence.
Fully legal and regulated under the Gambling Act 2005. Only operators holding a UKGC licence may lawfully offer gambling services to British residents.
Check for a UKGC licence number in the footer, look for SSL encryption (the padlock icon in your browser bar), and read the terms and conditions. Reputable casinos also use independent game testing from eCOGRA or iTech Labs. Every casino we list has passed all these checks.
Visa debit, Mastercard, PayPal, Apple Pay, Paysafecard and bank transfer are the most common options. Credit cards have been banned for UK gambling since April 2020. E-wallets typically offer the fastest withdrawals — often under 24 hours.
Yes. Every casino we review works on mobile browsers (iOS and Android). Several also offer dedicated apps. Most games, including live dealer tables, run without issues on smaller screens.
Register at gamstop.co.uk to block yourself from all UKGC-licensed sites for 6 months, 1 year or 5 years. It's free and takes a few minutes. Individual casinos also offer their own deposit, loss and session limits in account settings.
No. We're a review and comparison site. We don't hold a gambling licence, don't accept bets and don't host any games. When you click a link to a casino, you leave our site and go to that operator's own platform.

SlotGrader is an affiliate website. We may earn a commission when you click through and register at a casino — this costs you nothing extra. Commercial relationships never affect our scores or editorial judgement. All listed operators are independently assessed against the same criteria.

We don't run gambling services, accept wagers or host games. All brands and trademarks are the property of their respective owners. Gambling involves risk. Players must be 18+. T&Cs apply to every offer mentioned on this site. Please gamble responsibly.
