Year: 2023 Published: 1 Nov 2023 Type: Prison · Cat C Population: 240 Recommendations: 4 Key concerns Positive findings

HMP Warren Hill, a Category C adult male prison with an operational capacity of 267, maintained a safe environment despite some low-level bullying. The Board noted improved use of safety interventions (CSIPs, ACCTs) and zero deaths in custody. Key challenges included persistent issues with food provision, the suspension of the ROTL pilot, and delays in progression caused by Secretary of State interventions. The IMB made recommendations regarding food quality, estate investment, digital skills for resettlement, and urges review of the ROTL suspension.

Positive findings

Warren Hill is a prison that feels safe for both prisoners and staff. The IMB is pleased to report an increase in the use of CSIPs and ACCTs, demonstrating staff training has been beneficial. Prisoners are involved in decision-making and have attendance at many formal meetings. The standard of healthcare provision is generally like that in the community. Success at parole hearings continues to be high. The on-site approved premises are welcomed and beneficial for prisoners. The IMB commends the prison's commitment to the Enabling Environment accreditation and notes the impressive skill of prisoners working with raptors.

Key concerns

9 items
Food/Catering Repeated Ongoing concerns about the provision and quality of food provided by the Hollesley Bay kitchen.
Regime/Time Out of Cell The recent decision to suspend the ROTL pilot.
Other Repeated The transfer of prisoners’ property is still a major concern for the prisoners themselves and causes a lot of administrative hassle.
Estate/Conditions There are some areas of the prison where further investment is required and although work is currently underway on one of the shower blocks there still remains much outstanding work.
Resettlement/Release Repeated The IMB would like to see further development in resettlement support, including the use of digital technologies which are so critical to successful functioning in the modern world.
Education/Purposeful Activity Staff shortages continued to affect People Plus, the education provider, which in turn has impacted on the learners at Warren Hill. The IMB are disappointed that People Plus and the prison are still bound by a restrictive contracts process.
Resettlement/Release The intervention (as of May 2023) by the Secretary of State to delay and in some cases prevent movement to category D conditions or to release following successful parole hearings, which has had a serious impact on the mental health and wellbeing of many prisoners affected.
Healthcare There are discrepancies between local authorities when it comes to the funding of social care. Prisoners who come to the prison from, for example, Norfolk are unable to bring equipment with them, and funds and equipment must be reapplied for from Suffolk. This takes time and there is some evidence that Suffolk County Council has been unable to make funds available.
Regime/Time Out of Cell Prisoners have expressed dissatisfaction about pay levels, which are fixed by Warren Hill but appear to be inconsistent across the prison estate. Discontent is further fuelled by the effect of the increasing costs of items they wish to purchase.
