Prison service instructions and Prison service orders

Prison service instructions (PSIs) and Prison service orders (PSOs) set out the rules and regulations that determine how prisons are run. Both are defined and managed by HM Prison Service.

PSIs are guidelines that convey short-term instructions to prison staff. They are subject to periodic review and have a fixed expiry date. PSOs are longer-term mandatory instructions that can last for an indefinite period.
