How we rate UK casinos
Our 4-axis CasinoIndex evaluates every operator on bonus value, games, player safety, and customer support. Each axis is scored out of 100; the overall CasinoIndex is the blend. Here is exactly what each axis measures and how we score it.
Bonus
What we measureHeadline value, wagering generosity, eligible-game breadth, max-cashout caps, and bonus-code redemption friction.
How we score itTop score: a bonus with sub-30x wagering, no max-cashout, and slot eligibility above 90%. We mark down steep wagering, narrow eligible-game lists, low conversion caps, and clunky claim flows.
Games
What we measureLibrary breadth across slots, table games and live dealer; provider count and quality; mobile coverage.
How we score itTop score: thousands of slots from recognised studios, deep table-game and live-dealer rooms, and a mobile lobby that mirrors desktop. We penalise thin libraries and missing live coverage.
Player Safety
What we measureKYC and withdrawal-verification practices, responsible-gambling tooling, and complaint history.
How we score itTop score: fair, timely identity verification and a full set of safer-gambling tools (deposit limits, time-outs, reality checks, self-exclusion). We mark down slow or opaque verification and thin safer-gambling controls.
Customer Support
What we measureChannel availability (live chat, email, phone), response times, and the quality of help on bonus and withdrawal queries.
How we score itTop score: 24/7 live chat with fast, accurate answers on wagering and cashout questions. We mark down email-only support and slow or scripted responses.
Why CasinoIndex matters
A single star rating hides the trade-offs that actually decide whether an offer is worth claiming. By splitting the score into four axes, CasinoIndex shows you where an operator is strong and where it is not — a big bonus with punishing wagering will score high on Bonus headline but lower once safety and support are weighed. We verify bonus terms by hand and stamp each page with the month it was last checked, because bonus pages change faster than reviews. Every operator we list is commercially independent of its score: we may earn a commission when you sign up through our links, but that never moves the ranking.
