How We Rate Betting & Casino Sites

By the Odds Harbour editorial teamLast updated: How we rate

We only list operators licensed by the Gambling Commission of Great Britain. Each site is assessed on six weighted criteria — offer terms, payments, markets, features, safer gambling tools and support — and every offer shows the date we last checked it. Commission never buys a place in our rankings.

Criteria and weights

CriterionWeightWhat we check
Licence and safetyPass/failActive Gambling Commission licence for the domain, checked on the public register. Without it a site is not listed.
Welcome offer terms25%Qualifying stake, minimum odds, expiry, excluded payment methods, wagering (casino) and how clearly terms are shown — not the headline amount.
Payments and withdrawals20%Supported methods, minimums, fees and the time a withdrawal actually takes, measured on a real account.
Markets and odds20%Depth of football and racing markets, in-play coverage and price competitiveness on popular events (casino: game range and providers).
Features and app15%Cash out, bet builder, streaming, Best Odds Guaranteed, app stability and speed.
Safer gambling tools10%How easily you can find and set deposit limits, reality checks, time-outs and self-exclusion.
Customer support10%Channels available and whether they resolve a real question.

Where we are now

This site is new. Scores are published only after a site has been tested on a real account using the criteria above, so listings without a score have not completed testing yet, and their order is editorial. Facts we have not verified are shown as “being verified” or a dash — we do not estimate or copy unverified figures.

How we verify offers

How we make money

At the moment we have no commercial agreements with any operator. If we join an operator’s affiliate programme, links to that operator will be marked #ad and this section will say so. Commission will never decide the order of our lists.
