Prison service orders (PSOs)

Policy and guidance for prison and probation professionals in England and Wales.

Applies to England and Wales

Index and notes

This page lists all current prison service orders (PSOs). From 2010, new prison operational policies were issued as prison service instructions (PSIs).

If the PSO you want is not listed here, check the PSO index. This document lists every PSO issued and includes details of those which have been cancelled, updated or replaced by a PSI or policy framework. The index also includes the most up-to-date contact details for the owner of each PSO.

A PSO remains in force until it is formally cancelled, even if the document has passed its expiry date.

Some PSOs are not published here because they are restricted or sensitive. HR and other staff-related PSOs are not published here but are available on departmental intranets.

If you have any questions about the contents on this page or would like an electronic copy of a cancelled policy, please , email
