HMP Warren Hill

Report on an unannounced inspection of HMP Warren Hill by HM Chief Inspector of Prisons 3–21 February 2025.

Warren Hill healthy prison scores

What we found

The prison was providing an impressively strong and supportive culture, with very little violence or drug use. There were good relationships between staff and prisoners and a level of engagement rarely seen elsewhere. Almost all of the men were in full-time purposeful activity and prisoners were unlocked for more than 11 hours on Mondays to Thursdays. Living conditions were well-maintained, with prisoners housed in single cells and able to cook for themselves. Facilities included a coffee shop, barber and well-stocked prison shop.

Points to note: Despite the many positives, there was some disgruntlement among prisoners, some of whom had expected more from the jail. Furthermore, half of those released from Warren Hill were being recalled to custody and leaders needed to address this.
