Question to the Ministry of Justice:

To ask the Secretary of State for Justice, what the median length of service was for prison officers in the latest period for which data is available.

The median length of service for all band 3-5 prison officers in post on 30 June 2025 was 5.2 years.

The length of service in HMPPS is calculated from most recent hire date. Where staff have transferred in from another Government Department or have transferred in through HMPPS taking over a function, length of service is calculated from entry to HMPPS, and therefore the median presented excludes experience in other roles, including in private prisons. Band 3-5 officers includes Band 3-4 / Prison Officers (incl specialists), Band 4 / Supervising Officers, and Band 5 / Custodial Managers.
