The measures behind the bands
Position is where the prison sits among its 31 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.

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.
| Outcome | Actual | Model expects | Similar prisons | Expected (used) | Actual ÷ expected | Reading |
|---|---|---|---|---|---|---|
| Prisoner-on-prisoner assaults | 436 | 423 | 356 | 388 | 1.12× | About as expected |
| Assaults on staff | 84.6 | 167 | 125 | 144 | 0.59× | Lower than expected, but within what chance and recording differences could produce |
| Self-harm incidents | 935 | 895 | 656 | 766 | 1.22× | About as expected |
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.
| Share of population | This prison | Group median |
|---|---|---|
| Average population | 1,437 | 904 |
| On remand (untried or convicted, unsentenced) | 56% | 59% |
| Sentence under 12 months | 8% | 8% |
| Sentence 12 months to under 4 years | 11% | 9% |
| Sentence 4 years or more (determinate) | 6% | 6% |
| Life or IPP sentence | 1% | 0% |
| Recalled to custody | 17% | 15% |
| Aged under 25 | 16% | 16% |
| Aged 50 or over | 12% | 13% |
| Releases in the year, per prisoner held | 0.82 | 0.83 |
| Prisoners held in crowded accommodation | 56% | 56% |
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: 8.6 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
53.5% of 897 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: 57.6%. 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.
Disorder incidents and finds
| Per 1,000 prisoners, 2025/26 | This prison | Group median |
|---|---|---|
| Incidents at height | 165 | 84.0 |
| Barricades | 0.0 | 15.5 |
| Drug finds | 177 | 338 |
| Weapon finds | 133 | 144 |
| Mobile phone finds | 75.1 | 92.7 |
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: 6 releases in error; 4 active concerted indiscipline incidents; 6 passive concerted indiscipline incidents; 1 hostage incident.

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