How we rank

Licensed businesses are ordered by our Standing Score v1, 0 to 100, built only from public records: years since the license was first issued (up to 35, capped at 20 years), a full classification with no limitation (20), no expiry within 90 days (10), no board discipline in the last 5 years (15), the license's monetary limit (up to 10), and website, phone and opening hours listed on OpenStreetMap (up to 10). Ties go to the longer-licensed business, then by name. A signal we do not have scores 0 and is shown as not available.

Years licensed, discipline and monetary limit are still being collected from the board for this trade, so this order currently uses license class, expiry and contact details only.

Google ratings do not affect this order, and no business pays to be listed or ranked. Full methodology.
