Double bunking in prisons

Double bunking is a standard operational practice across the prison estate. Corrections staff use a comprehensive assessment tool called the Shared Accommodation Cell Risk Assessment (SACRA) to review the compatibility of prisoners before they are placed in a shared cell. The tool does not replace staff judgement, but helps inform their decision-making, and minimises any potential risk.

The SACRA report identifies key risk factors to consider before placing a prisoner in a shared cell. The assessment captures a range of information about the person, including their age, security classification, offending history, history of imprisonment, gang affiliation, notable physical characteristics, mental health concerns and any other special needs.
