Warren Hill has been both a juvenile establishment and an adult category C male offenders’ prison. In September 2014 it assumed its current role of a category C men’s prison for those on indeterminate sentences with a history of failing in open conditions or absconding; this group of prisoners are no longer eligible for open conditions or temporary release. Warren Hill is classed as a NOMS national resource.
In addition, the prison has a democratic therapeutic community (TC) that was separate from the progression regime; it had moved to Warren Hill in February 2014 from HMP Blundeston via for a short period of time HMP Norwich
