The measures behind the bands

Position is where the prison sits among its 50 peers on that measure alone (lower incident rates are better; higher grades and outcomes are better). For incident outcomes the position is after adjusting for who the prison holds.

Fourteen measures in four pillars, each pillar weighted equally.

Incidents compared with what we would expect

Rates are incidents per 1,000 prisoners over April 2025 to March 2026. The expectation is the average of a statistical model of who the prison holds (sentence length, remand, recalls, age, turnover, crowding) and the average of its HMPPS comparator prisons. Neither includes the prison's own result.

OutcomeActualModel expects Similar prisonsExpected (used)Actual ÷ expected Reading
Prisoner-on-prisoner assaults1131402051700.67×Lower than expected, but within what chance and recording differences could produce

A flag appears only when the result is outside statistical limits and in the same direction under the model, the comparators and their average. It is a prompt to look, not a finding of fault. Counts of one or two incidents are suppressed in the source and estimated here.

Similar prisons

HMPPS names these prisons as the closest comparators, matching on age, sentence length, turnover, sex-offender share, complexity, building age and setting. Rates are per 1,000 prisoners; reoffending is the share of people released in April 2023 to March 2024 who reoffended within a year.

Who the prison holds

These describe the population, not the prison's performance. They are what the expectations above adjust for. Averages over the four quarter-ends of 2025/26.

Remand is decided by courts and recall by probation and the Parole Board. They are context here, not something a prison controls.

Also shown, not scored

Staff sickness and resignations

Sickness: 9.4 days per full-time employee (HMPPS target 9). Contracted prisons report this through a different route, so it is not compared with public prisons.
Resignation rate: Not published for contracted prisons.

Contracted prisons report sickness through a different route, so no position is given. Related to quality in our tests, but the direction of cause is unclear, so it is not scored.

Reoffending after release

33.2% of 1,024 people released in April 2023 to March 2024 reoffended within a year. Expected given who is released and the mix of the prison and its comparators: 26.6%. Result: about as expected.

The Ministry of Justice says rates by releasing prison should not be used to assess prisons: they do not control for sentence or offender characteristics, and the prison of release may not be where the sentence was mainly served. About two years old.

Not scored. We cannot separate real disorder from differences in how incidents are recorded, and more finds can mean better searching rather than more contraband. Also recorded: 1 escape from an HMPPS escort; 2 releases in error; 1 active concerted indiscipline incident; 1 hostage incident.

The CQC does not give prison healthcare a graded rating, so this is context only.
