Question to the Ministry of Justice:

To ask the Secretary of State for Justice, what the average cost was of (a) a prison place, (b) the supervision of a person on licence following release from prison and (c) the delivery of a community order by the Probation Service in the latest 12 month period for which data is available.

Information on the average annual cost per prisoner, cost per prison place and overall prison unit cost for each private and public sector prison in England and Wales is published by His Majesty’s Prison and Probation Service (HMPPS) after the end of each financial year on the gov.uk website.

The overall average cost for running a prison place for a year (per prison place) in 2022-23 was £51,724. This information can also be found through the following link: https://www.gov.uk/government/publications/prison-performance-data-2022-to-2023.

The Ministry of Justice expects the 2023-24 Prison Unit Cost data to be published in December 2024, once the 2023-24 HMPPS Annual Report & Accounts have been published.

The average cost to the Probation Service in 2023-24 of an additional person on the probation licence caseload (including probation pre-release costs) was estimated at c.£4,500 compared with c.£3,150 for an additional person on the probation court order caseload (community orders and suspended sentence orders). This can be found through the following link: https://assets.publishing.service.gov.uk/media/65537c7d50475b000dc5b590/Sentencing_Bill_-_IA_-_HDC.pdf.

Note that the costs presented exclude some costs to the Ministry of Justice, such as the costs of building prisons, costs not directly tied to changes in probation caseload and MoJ HQ costs.
