HMP Wolds opened in April 1992 as a remand prison and in 1993 was re-roled to a local category B prison holding sentenced prisoners. The initial management contract ran for five years and was renewed for a further five years in 1997. In 2001, HMP Wolds was subject to a competitive re-bid. G4S was the successful bidder for the contract to run HMP Wolds as a category C training prison for a further 10 years.
HMP and YOI Ashfield opened on 1 November 1999 and accommodated both juveniles (aged 15 to 17) and young offenders (aged 18 to 21) until February 2004 when it was re-roled as an all juvenile establishment holding young people between 15 but under 18 years of age.
Performance Management Group (National Offender Management Service) owns and manages the Prison Performance Assessment Tool (PPAT) which assesses around 120 public prisons by looking at performance in 33 indicators, which is then cross checked with a rating produced by assessing against a set of 44 indicators in the public prison weighted scorecard. For private prisons only the PPAT is used to produce the data driven assessment. Both HMP Ashfield’s and HMP Wolds’ performance ratings were published on 12 December 2008 and are available via the following link:
In the most recent published ratings (quarter 2) both prisons achieved a level 3 rating for good performance.
