How we rate online casinos
Six weighted criteria, a score out of 10, and sources limited to the Gambling Commission register and the operators' own documents.
Every operator on All British Casinos gets a score out of 10, built from six criteria with fixed weights. The score comes only from public documents: the Gambling Commission's public register and the operator's own terms and conditions, bonus rules, help-centre pages and app store listings. We do not open accounts, deposit or play, and no operator can pay for a score.
Licensed operators only
Before anything is scored, the operator must hold an active remote licence from the Gambling Commission for the product shown. The licence holder, account number and listed domains come from the register. An operator without an active GB licence is never listed, ranked or linked, whatever its offer.
The six criteria and their weights
| Criterion | Weight | What is assessed |
|---|---|---|
| Licence | 20% | Active GB licence, clear licence holder, domain on the register, any published regulatory action |
| Terms | 25% | Wagering, caps, expiry and how clearly the significant terms of offers are written |
| Payments | 15% | Methods published, minimum deposit, withdrawal rules and stated processing times |
| Safer gambling | 15% | Deposit limits, reality checks, time-outs, self-exclusion and GAMSTOP information |
| Games | 15% | Range of games and studios named in the operator's own lobby and documents |
| Transparency | 10% | How easy it is to find who runs the site, the full terms and the complaints process |
Each criterion gets a sub-score from 0 to 10. The overall score is the weighted average, rounded to one decimal place. Terms carry the most weight because the small print decides what an offer is really worth, and since 19 January 2026 Great Britain's rules cap bonus wagering at 10x and require terms to be clear and easy to find.
What the score words mean
- 9.0 to 10: Excellent
- 8.0 to 8.9: Very good
- 6.5 to 7.9: Good
- 5.0 to 6.4: Fair
- Below 5: Weak
Operators with register facts only
Some licensed operators are listed while their own documents cannot yet be read in full, for example when the terms are behind a login. Until they can be, those operators get default sub-scores for the criteria that depend on their documents, and their pages say that current offer and payment details are set out in the operator's own terms. Their scores are updated once the documents are read, and they are never described beyond what the register shows.
Updates and corrections
Offers and terms change often. Scores are rechecked against the current documents, and each terms sheet shows the date it was last checked. If you spot a fact that has changed, the contact page explains how to tell the editors. Who does the checking is set out on the editorial team page, and how affiliate income is kept apart from scores is explained in the advertising disclosure.
Questions readers ask
Can a casino pay for a higher score?
No. Scores come only from the six criteria and the public documents behind them. Commercial relationships do not change sub-scores or ranking order.
Do you test casinos by playing?
No. Scores are built from the Gambling Commission register and the operators' own published documents, not from accounts, deposits or play.
Why is an operator with a big bonus scored lower than one with a smaller offer?
Terms are scored on wagering, caps, expiry and clarity, not on headline size. A smaller offer with fewer restrictions can score higher.
