Positive findings

AI-generated summary
HMP Stocken is generally a safe place for both prisoners and staff, with physical health provision considered as good as that in the community. The quality of interactions between staff and prisoners on ACCTs has improved, and the diligence of staff in identifying illicit drug sources is commended. Processes for self-isolating prisoners have improved, and the ethnic diversity of prison officers continues to increase. The Board acknowledges the invaluable contribution of the chaplaincy team and notes improvements in complaint responses and the introduction of a social prescribing link worker. Adjudications are conducted well, and progress with DIRFs is seen as a strength of the prison. The Minister also praised the leadership's clear vision and efforts to support prisoners nearing release.

Key concerns

12 items
Regime/Time Out of Cell Repeated The Board is concerned that prisoners’ excess personal property will continue to be lost or mislaid, as long as all ‘sending prisons’ are not required to enforce the same volumetric property controls.
Mental Health Repeated It takes too long to transfer prisoners with mental health problems to secure mental health facilities, often resulting in prolonged stays in the CSU.
Resettlement/Release Repeated As noted in last year’s report, there has been an increase in the number of prisoners held at HMP Stocken who are out of the area. This, coupled with the rural location of the prison, makes keeping family ties difficult. Although social video calls are available, not every prisoner’s family have the knowledge or means to make use of this facility.
Safety Repeated Given that HMP Stocken is one of the larger public-run prisons in England, when is ‘enhanced’ gate security going to be improved with up-to-date equipment?
Estate/Conditions Repeated With the ageing prison population, when are more cells suitable for those with disability or mobility issues going to be made available? Even on the new wing opened last year, there are no ‘disabled’ cells, only two ‘low mobility’ cells, which can’t accommodate a hospital bed.
Other Certain prisoners held in the CSU on suspicion of illicit activities are not sufficiently briefed by the security department about the reasons for their investigation.
Equality/Diversity Some members of the SMT don’t seem to be fully committed to the aims of the equality and diversity department, particularly in regard to the implications of the wealth of data available on a monthly basis.
Other With constant moves of prisoners in and out of HMP Stocken, it is difficult to recruit and maintain prisoner representatives.
Healthcare The healthcare unit has gone through a difficult period this reporting year, with a high turnover in staff, although, from the Board’s observations, they have worked hard to limit the impact this has had on the prisoners. However, one result of this has been that there has been long delays in healthcare staff replying to prisoners’ applications/complaints.
Healthcare As reported below, a new pharmacy opened towards the end of the reporting year. However, a number of prisoners have reported issues in applications to the Board. It is hoped that the appointment of permanent pharmacy technicians, rather than relying on agency staff, will improve the situation.
Estate/Conditions However, despite some repairs being carried out, the oldest wings are showing signs of their age.
Regime/Time Out of Cell However, towards the end of the reporting year, the amount of time prisoners spend out of their cells in the late afternoon/evening period has been restricted. This is due to the increased drone activity.

Recommendation 1

Addressee: Other — minister

Given that HMP Stocken is one of the larger public-run prisons in England, when is ‘enhanced’ gate security going to be improved with up-to-date equipment?

Repeated Source text verified

Government response
I have read your report carefully and note your request for an update on Enhanced Gate Security (EGS). EGS is one of the priorities of both the Governor and Prison Group Director with funding and resources being made available earlier this year. However, the quote to complete the work far exceeded the funding agreed. The physical space inside the gate house is simply too small to fit all of the equipment and associated infrastructure. Therefore, either sizeable building works were required, or the installation of a modular unit to accommodate everything required. This scope increased the costs to well above the financial threshold approved. However, an x-ray baggage scanner was provided to the prison in February 2024 to enhance HMP Stocken’s prisoner property searching capabilities.

Recommendation 2

Addressee: HMPPS

With the ageing prison population, when are more cells suitable for those with disability or mobility issues going to be made available? Even on the new wing opened last year, there are no ‘disabled’ cells, only two ‘low mobility’ cells, which can’t accommodate a hospital bed.

Repeated Source text verified

Government response
It is recognised that the rise in the number of older prisoners over the past 20 years has caused issues for some prisons, particularly around their often complex health and social care needs. The physical prison estate can present challenges for this cohort, and the new prison places we are building are accessible by design and will significantly increase the number of cells adapted to the needs of those with mobility issues and physical disabilities across the estate. At HMP Stocken there are a number of accessible cells available that are occupied by prisoners on the recommendation of healthcare, based on the level of need. There are also a number of other reasonable adjustments (e.g. fitted hand rails) that have been made to standard cells to support prisoners with varying needs.

Recommendation 3

Addressee: HMPPS

Until ‘sending prisons’ are required to apply volumetric controls, property in excess of these will continue to be mislaid or lost. When will the Prison Service enforce its own restrictions on transferring prisoners?

Repeated Source text verified

Government response
HMPPS note the Board’s concerns about the handling of prisoners’ property. The findings in the IMB national thematic report on how property loss impacts on prisoners, as well as those received from Independent Prisoner Complaint Investigations following a thematic review of the property complaints they have received in the last five years, are being considered. Since receiving the reports, Governors and other senior leaders have been reminded of the most important property handling points. This includes the need to ensure compliance with volumetric control limits. Consultation is taking place with prisons on further areas raised in the reports. Locally, HMP Stocken has put measures in place to limit the amount of property that prisoners can have in possession, including not accepting perishable items such as consumables.

Recommendation 4

Addressee: Governor / Director

The Board is concerned that certain prisoners held in the CSU on suspicion that they are involved in illicit activities within the prison are not sufficiently briefed by the security department about the reasons why they are under investigation.

Topic: Fair Treatment

Recommendation 5

Addressee: Ministry of Justice

It takes too long to transfer mentally ill prisoners to secure mental health facilities. This often means that they have to be held in the care and separation unit (CSU) for their own safety for extended periods of time.

Repeated Source text verified

Government response
The Ministry is working with the Department of Health and Social Care to introduce a Mental Health Bill as soon as possible. This will introduce reforms to improve access and support for patients in the criminal justice system, bearing in mind the pressures on such services nationally. NHS England will continue to escalate the demands for places within the prison population.
