Privately managed prisons were introduced to the UK in the 1990s.
HM Chief Inspectorate of Prisons inspects private prisons in the same way as public sector prisons. All private prisons have a 'Controller' linking them to the National Offender Management Service, and the governors of private prisons are called 'Directors'.
At present there are 14 private prisons contractually managed by private companies such as Sodexo Justice Services, Serco and G4S Justice Services.
