Thorn Cross

IMB Annual Report 2023 · Published 4 August 2023

HMP/YOI Thorn Cross is a Category D open prison that maintains a very safe environment with extremely low violence levels and effective drug reduction strategies. Relationships between staff and prisoners are generally positive, fostering a rehabilitative culture. While healthcare provision is deemed excellent and rehabilitation efforts are at the heart of the prison's operations, concerns remain regarding low transfer rates for long-sentence prisoners, property transfer issues, and limitations in internet and mobile phone access for prisoners.

Positive Findings
HMP/YOI Thorn Cross is a very safe establishment with good staff-prisoner relationships and a strong rehabilitative culture. Healthcare provision is considered excellent, comparable to or better than community services, and substance misuse support is particularly strong. Education attendance and success rates are high, with a well-stocked library and effective employment and training strategies leading to a reduction in absconds and improved post-release support.
Key Concerns
Resettlement/Release
The low transfer rate of lifers and IPP prisoners compared to previous levels, impacting their rehabilitation.
Other
The need to reconsider the re-sentencing of IPP prisoners.
Other Repeated
Continuing issues with the transfer of prisoner property, leading to items going missing and slow resolution.
Education/Purposeful Activity
Lack of limited internet access for prisoners undertaking university and college courses.
Regime/Time Out of Cell Repeated
Lack of mobile phone access for remote visits, especially for prisoners living far from the prison or those on the TPRS scheme.
Safety
Failure to use Body Worn Video Cameras for every instance where force is used, with only 24 of 82 incidents recorded.
Safety
The need to review the guidance for the use of cuffs, especially rigid cuffs, ensuring their use is based on current risk assessment rather than past events.
Food/Catering
Unsuitable current proposals for central dining that will not resolve issues with food quality due to long waits in heated trolleys.
Complaints/Property
Poor recording of adjudication outcomes, making it difficult to determine the justice of decisions when tariffs are outside recommendations without stated reasons.
Regime/Time Out of Cell Repeated
Ineffectiveness of the Prison Council as a means of consultation and communication, with frequent cancellations and unclear follow-up.
Equality/Diversity Repeated
Limited analysis of prison activity by protected characteristics and insufficient availability of such data for areas like use of force or random drug testing.
Other
Irregular and untimely provision of information and evaluation of prison performance to the Board.
Food/Catering
Poor facilities for prisoners who wish to cook their own meals, offering fewer resources than some Category C prisons for independent living.
Mental Health
Lack of mental health provision available in the evenings and at weekends, despite an acknowledgement of the need for 7-day access.
Regime/Time Out of Cell
Lack of a suitable strategy for men transferred under the Temporary Re Categorisation Scheme (TPRS), with concerns about its destabilizing impact and their inability to benefit from rehabilitation.
Education/Purposeful Activity
Disruption for prisoners attending education due to being required to be elsewhere during the core day.
Board Commentary
Staffing
Staff absence has significantly decreased, aiding stability. However, some staff remain on temporary promotion, impacting long-term stability. While healthcare staffing is nearing full capacity after recent appointments, the Offender Management Unit remains understaffed, leading to high caseloads. Staffing shortages also occasionally affect relationships with prisoners and the consistency of gym opening hours.
Healthcare
Healthcare provision is generally excellent, often surpassing community standards, with most needs met on-site. Substance misuse support by CGL is particularly strong, serving about a third of the population. New investment in mental health services is planned, aiming to expand capacity and staffing, including out-of-hours provision. GP waiting times are currently around two weeks, impacted by recent population increases and prior staffing gaps, now being addressed.
Regime & Daily Life
The prison has restored its pre-pandemic regime with gradual changes. While the gym now offers consistent opening hours, overall regime flexibility is limited, with few facilities for prisoners to cook their own food. Meals often suffer from long waits in heated trolleys, and the proposed central dining room is not expected to resolve this. Disruptions to education for other prison activities and the lack of supervised mobile phone use are ongoing issues.
