How the regional group is defined
We include 13 establishments whose administrative region in the import matches “LONG TERM & HIGH SECURITY ESTATE”. Region names and boundaries follow the source data; if a site sits near a border, check the establishment profile and official listings.
Figures and labels on Prisons Online come from the HMPPS prison export used in this build. Security category and function wording are administrative fields in that source (and category may be inferred where the export does not map cleanly). Always confirm visiting rules, contact details, and regime information with official HMPPS or GOV.UK sources.
