Prisons data

Safety and order

Prisons need to be and feel safe for both staff and prisoners. Violent incidents are the most obvious issue, but this is also about wider culture and atmosphere of the prison and the support it provides to vulnerable prisoners.

Audits and inspections are reported on a 4-point scale,from 1 (lowest rating) to 4 (highest rating).

MQPL safety audit

The MQPL survey of prisoners' perceptions is a validated way of gauging the quality of Decency and Safety, which are vital business aims but difficult to define and measure by other means.

Questionnaire scores are made more meaningful by comparing them to what might typically be expected from prisons of a similar type, but the comparison should not be judged at face value without reference to the specific context of the prison in question.

The MQPL survey is undertaken as a part of a rolling three-year programme. The data presented here shows the most recent assessment for each prison establishment

The summary percentage is based on audits published internally by HMPPS. The annual prison performance ratings publication includes audits which had not been published when it was released and were therefore suppressed from the data tables. Including these suppressed scores, the overall percentage of prisons scoring a 3 or 4 is 80.5%

Values:

• Rating 1: 7 prisons
• Rating 2: 16 prisons
• Rating 3: 85 prisons
• Rating 4: 10 prisons
