A daily rebuilt record of prisons, young offender institutions and immigration removal centres across England and Wales.

Landing page captured for the 2026-09-13 issue.

Field notes

The project assembles prison-estate information from official releases into a daily rebuilt database, then exposes it through a map, historical establishment pages, national bulletins, and recall tables. The page reports 123 establishments and separates figures by release cadence: its national snapshot covers the week ending 7 September 2026, while establishment figures are dated 24 August. Developers can retrieve JSON or GeoJSON, and the site says even failed ingestion runs are logged.
