Buckley Hall was the 4th contracted-out prison in the UK, and the first privately managed category C establishment holding medium-security prisoners, and was operated by Group 4 Prison Services. After a tendering process in June 2000, the establishment reverted to Prison Service control. In April 2002 it re-roled to a closed female training prison. As a result of population pressures in the male estate, it was then re-roled back to a male category C prison in September 2005.
