How we rank UK casino sites
Our rankings aren't paid placements. Each site is scored against the same criteria so you can compare like for like. Commercial relationships with operators never change the order — they only fund our testing.
Our scoring criteria
- Bonus value & fairness — headline size matters less than realistic wagering requirements.
- Game library — number and quality of slots, plus provider variety (Pragmatic, NetEnt, Play'n GO).
- Withdrawal speed — how quickly we actually received our money in testing.
- Licensing & safety — a UKGC licence is mandatory; we verify it before listing.
- Mobile experience — most UK players use mobile, so we weight it heavily.
What to look for in a UK casino site
A big welcome bonus is eye-catching, but the wagering requirement determines whether it's actually worth claiming. A "100% up to £100" offer with 35x wagering is usually better value than "200% up to £200" at 65x. Always read the terms.
Wagering requirements explained
Wagering (or "playthrough") is how many times you must bet a bonus before withdrawing winnings. A £50 bonus at 35x means £1,750 in bets. Lower is better — and a handful of sites now offer wager-free spins, which we flag in the table above.
Frequently asked questions
Are these casino sites legal in the UK?
Yes. Every site we list holds a licence from the UK Gambling Commission, which is a legal requirement to offer real-money gambling to UK residents.
How do free spins work?
Free spins let you play selected slots without using your own balance. Winnings may be subject to wagering unless the offer is explicitly "wager-free".
