What this page is for
This article explains how we list prisons associated with “G4S” in our England and Wales listings. It complements the operator hub page, which shows the live grid for that label.
Operator strings are taken from the HMPPS export; management arrangements can change, so treat the label as a directory snapshot rather than a legal description of the contract.
Establishments in this operator group
We currently list 6 establishments sharing this operator label.
Examples include: HMP Five Wells, HMP Oakwood, HMP Rye Hill, HMP/YOI Altcourse, HMP/YOI Parc. Full membership is linked below and on the operator hub.
Figures and labels on Prisons Online come from published HMPPS prison information. 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.
Frequently asked questions
- Does “operator” mean the prison is privately run?
