HMP Everthorpe Created as a
borstal in 1958, Everthorpe was converted to house male convicts in 1991. After a two-day riot during the Christmas and New Year period of 1995/1996, the prison was criticised for its lack of security, bad management and the deployment of inexperienced staff during the riot. The prison was substantially expanded in 2005, but was criticised by the
Chief Inspector of Prisons in 2006 because places on resettlement and offending behaviour programmes had "failed to keep pace" with the increased number of prisoners held at the prison.
HMP Wolds In 1991,
G4S won the UK's first private sector prison management contract. Initially a
remand prison, HMP Wolds opened in April 1992, becoming a local Category B prison holding sentenced prisoners in 1993. In 2001, HMP Wolds was re-rolled again to a Category C training prison, holding adult males (including prisoners serving second stage
life sentences). The prison reverted to the public sector in 2013.
Merger In June 2013, it was announced that HM Prisons Everthorpe and Wolds would be merged into one larger prison, to be named HMP Humber. The merger took effect in April 2014 and a secure connecting corridor between the two prisons was completed in May 2015. However, the merger was said to have been "traumatic and prolonged", according to a
HM Inspectorate of Prisons report, with "significant" delays in the corridor being built and changes to the staffing structure. ==Current prison==
