• SafetyGood
• RespectReasonably goodDown marginally from good
• Purposeful activityGood
• Rehabilitation and release planningGood

HMIP’s unannounced inspection (report published 14 August 2023) was its first full inspection since 2016. The Chief Inspector described Thorn Cross as having ‘consistently been a successful institution’, overwhelmingly safe, with violence rare and absconds lower than nearly all comparable prisons.

In its survey, 99% of respondents felt safe on their first night. Open conditions mean prisoners are not locked up, and release on temporary licence (ROTL) was used extensively for home visits and paid work outside. Ofsted judged education, skills and work ‘good’.

Staffing and leadership evidence

In shortGood operational staffing and a respected governor, though some staff were deployed elsewhere and some offender management staff needed a more supportive stance.

The governor was described as proactive and respected with a clear vision. Relationships between staff and prisoners were positive, though some offender management staff needed to adopt a more open and supportive stance. A new offender management unit building was being built at inspection.

IMB annual report, May 2025 to April 2026

In shortThe IMB said Thorn Cross remains safe with a strong rehabilitative culture, but noted a weak kitchen, cut courses and rising need.

The IMB’s report, published in August 2026, said Thorn Cross remains safe, with low levels of violence and relatively low self-harm. Relationships between staff and men were ‘good natured and supportive’, and the prison maintains ‘a strong rehabilitative culture with excellent figures for accommodation and employment on release’.

• A significant increase in the number of men needing support, reflecting a changing open-estate cohort, and a new trend of unregulated weight-loss injections.
• The kitchen is inadequate for the prison’s size and had equipment failures.
• Residential units would benefit from investment, and some education courses were cut because of reduced provision.
• A replacement building completed in February 2026 was only occupied in late April because of contractual issues.
• Health care and support for addiction were described as good or excellent.
