Belmarsh

Year: 2025 Published: 28 Nov 2025 Type: Prison · Cat Category A local Population: 730 Recommendations: 13 Key concerns Positive findings

HMP Belmarsh is a Category A local prison facing significant challenges during the reporting year ending June 2025. The Board noted a concerning rise in violence, strain on staffing impacting key worker sessions and daily regimes, and inadequate provision for vulnerable and seriously ill prisoners due to bed shortages and transfer delays. While staff professionalism and some positive initiatives were observed, persistent issues with property management, infrastructure, and purposeful activity, particularly for young offenders, require urgent attention.

Positive findings

The Board commends staff and senior leaders for their dedication and professionalism in maintaining a safe and positive environment despite daily challenges. Positive developments include new neurodiversity initiatives, improved support for remand prisoners, and successful vocational training courses. Significant efforts have been made in developing an incentivised substance-free living spur, which has positively impacted the houseblock atmosphere. The prison has also seen improvements in reducing out-of-action cells, external area cleanliness, and the overall quality of healthcare provision. The equality team's work and the chaplaincy's support are also highlighted as positive.

Key concerns

13 items
Safety There was a 14% rise in incidents of violence, and violence was most frequent in the young adult age group (18-25 years old). This was accompanied by a 22% increase in the number of weapons found in the prison.
Safety Repeated The Board observed another significant rise in the number of vulnerable prisoners (VPs) deemed to be at risk of being targeted by other prisoners. There are too many VPs to accommodate on the prison’s dedicated spur and, at the time of reporting, between 20 and 30 VPs were being held in cells on general spurs alongside other prisoners.
Safety Repeated Insufficient care was being taken in some cases to ensure the wellbeing of prisoners who self-isolate. IMB members noted several occasions during the year when houseblock records were not up to date and officers were not clear about how many prisoners were self-isolating.
Staffing There was a dramatic fall in the number of sessions between prisoners and their key workers. This was caused by a significant rise in the number of staff on sick leave. Staff absence also had a negative effect on the daily regime in the houseblocks, healthcare centre, segregation unit and the HSU.
Segregation The Board had raised concerns to prison management about several issues in the segregation unit: The number of multi-unlock close supervision centre (CSC) prisoners being held at Belmarsh. The number of spaces in the segregation unit for use by the prison - just eight - after CSC prisoners and out-of-action cells were considered. Officers were obliged to manage prisoners involved in serious incidents on the houseblocks rather than in the segregation unit. The number of young adults (under 25) and young offenders (under 21) being managed in the segregation unit.
Regime/Time Out of Cell Repeated The Board does not believe HMP Belmarsh is sufficiently well resourced to be a suitable location for these younger individuals.
Healthcare Repeated Seriously ill patients on ‘do not unlock’ regimes were treated on the prison’s houseblocks or in its segregation unit because cells were not available in the in-patient unit (IPU). The shortage of cells in IPU is due, in no small part, to the number of high-profile prisoners with life sentences who are being held in the unit. There has been a rise in the number of seriously ill multi-unlock patients in the prison awaiting transfer to a secure hospital setting. A transfer should take place within 28 days of a referral being completed but it is taking on average 80 days.
Healthcare Repeated There were disturbing cases of prisoners hoarding their medicine, cases of prisoners either not receiving their prescription or being prescribed the wrong medication, and concern was expressed by the Prison and Probation Ombudsman about dispensing procedures in the case of more than one death in custody.
Equality/Diversity Repeated The Board continues to be concerned about the failure to make proper provision for communicating with foreign national prisoners who struggle with English, especially in healthcare and at key worker sessions.
Resettlement/Release Repeated Although the numbers at Belmarsh have fallen over the year, the Board remains concerned about the situation of IPP (imprisoned for public protection) prisoners, some of whom have served much longer than their original minimum term and still have no clear route to release.
Education/Purposeful Activity Repeated The Board is particularly concerned about the lack of purposeful activity for category A young offenders (aged 18-21 years old) and the negative impact it has on their mental health.
Estate/Conditions Belmarsh is a relatively recent addition to the prison estate, but years of under-investment have started to show, and several areas of the prison need refurbishment.
Other Repeated The Board noted the frustration and stress prisoners experience when their property has been lost in the system. This remains the case, despite assurances from the Minister and HMPPS that the new Prisoners’ Property Policy Framework would improve the situation and outcomes.

#RecommendationAddresseeStatus
1 As set out in previous years’ reports, will the Minister require the Prison Service to urgently review its procedures on the transfer of property and introduce basic automated systems using available technology? Repeated
Response
I fully understand the Board’s continued concerns about the handling of prisoners’ property and appreciate your frustration that you have raised similar concerns in your last three reports. HM Prisons and Probation Service (HMPPS) has carefully considered the IMB national thematic report on the impact of property loss on prisoners, and the thematic review by the Independent Prisoner Complaint Investigations of the property complaints they have received over the last five years. In considering both reports, consultation with prison staff took place on the issues raised. A revised version of the Prisoners’ Property Policy Framework was consequently published on 17 November 2025 and includes additional guidance on the forwarding of excess property, the handling of prisoners’ laundry, and on the correct completion of the cell clearance certificate, as these issues have been identified as common areas of difficulty. Additionally, HMPPS has once again reminded Governors and other senior leaders of key points around property handling, including the importance of prisoners complying with volumetric limits. Compliance with volumetric control remains of key importance, since property within those limits (as well as certain items, such as legal papers, which are exempt from the limits) will be moved with prisoners when they transfer to other establishments. I also note the Board’s concerns about the lack of digital improvements on property handling. Whilst it is recognised this will be disappointing, other pressures around digital changes mean that it is not anticipated that an electronic property card will be in place in the immediate future. Please be assured that HMPPS remains committed to improving the management of prisoners’ property and considers possible areas for improvement on an ongoing basis.

2 Will the Minister take further steps to ensure that number of IPP prisoners continues to fall and that all remaining IPP prisoners have a clear route towards release? Repeated
Response
I can assure the Board that we are not standing still on the important issue of progressing those serving Imprisonment for Public Protection (IPP) sentences towards a prospective future release. As mentioned in last years’ response, we are continuing to support the rehabilitation of IPP offenders through the IPP Action Plan that was refreshed on 17 July 2025. The Action Plan now also includes measurable targets to ensure transparency and accountability. The refreshed Action Plan was published in our IPP Annual Report and can be accessed on GOV.UK. With public protection as the number one priority, we are working with organisations and campaign groups to ensure appropriate action is taken to support those still serving these sentences, such as improved access to mental health support and rehabilitation programmes.

3 Will the Minister work with colleagues across the NHS to provide more beds in secure hospitals to enable prisoners with acute mental health needs receive the most appropriate therapeutic treatment? Repeated
Response
With regard to the issues you raise around secure hospital transfers, NHS England and healthcare providers are focussing on ensuring that where people in prison have increasing and complex mental health presentations, there are services in place within the prison setting that can meet their needs, reduce further deterioration, and help people to stay well, thereby reducing the likelihood of an admission to inpatient services or external hospital. Where prison is not the right environment for a person with mental health needs, prompt referral to external services is made so that people can receive treatment in clinically appropriate settings. NHS England’s 2024/25 priorities and operational planning guidance reinforces this focus on improving patient flow as a key priority, with systems directed to reduce the average length of stay in adult acute mental health wards in order to deliver more timely access to local beds. To address the wider system issues that impact on health services, a further £1.6 billion has been made available via the Better Care Fund from 2023-25. This funding can be used to support mental health inpatient services as well as the wider system. This is being supplemented by a further £42 million recurrent investment from 2024/25 for all Integrated Care Boards in the country to recommission inpatient care, in line with local models that provide the best evidence of therapeutic support.

4 Will the Prison Service invest in the prison infrastructure at HMP Belmarsh to avoid continued deterioration in its facilities?
Response
HMPPS remains committed to maintaining safe, secure, and decent prison environments across the estate. At HMP Belmarsh, bids have been made for the installation of anti-drone wires and the replacement of the main generator. These projects are currently at an early stage of development and are progressing through the project assurance process and funding consideration. A range of other bids have also been submitted to HMPPS Estates. Projects currently estimated to complete by the end of the financial year include upgrade/replacement of visitor recognition system and key racking system and replacement of the residential unit fire alarm panel. The investment required across the estate is continually reviewed to ensure resources are allocated effectively. Within this pipeline, projects awaiting compliant and affordable bids include: replacement of the Building Management System, LV switch panel replacement, installation of a new fire alarm system, upgrades to showers in the High Security Unit, replacement of cell call systems, smoke extraction system improvements, CCTV network expansion, electrical locking updates, bomb door replacement, and fire door remedial works. Future proposals will be informed by data collected during recent condition surveys at each prison. These surveys will underpin long-term forward maintenance registers, enabling prioritisation against future capital budgets. Whilst all requests from establishments are considered carefully, demand for maintenance significantly exceeds available funding. Therefore, once a bid is received, HMPPS prioritises works to make best use of resources, focusing on projects that address risks to life, capacity, and decency.

5 Will the Prison Service look at the arrangements that are made for locating CSC prisoners at HMP Belmarsh? If a suitable location is not available, will it undertake to increase staffing?
Response
Allocation and placement of CSC prisoners is centrally managed and a representative from HMP Belmarsh forms part of the Close Supervision Centre Management Committee (CSCMC) who make final decisions regarding placements across the CSC estate. Due to an increase in referrals and other population pressures, there has been an increase in the amount of Designated Cell (DC) prisoners at HMP Belmarsh. This has been a temporary measure, and CSC prisoners are moved to a suitable unit location as soon a reasonably practicable. HMP Belmarsh is funded to hold two DC spaces to aid the overall management of the CSC estate. The prison receives funding for an additional two Band 3 Prison Officers to assist in the delivery of a regime to the CSC prisoner population located in DCs.

6 Working with the Governor, will the Prison Service look at the allocation of ‘high profile’ prisoners to HMP Belmarsh? Will the Prison Service consider an alternative location to in-patient unit in the healthcare centre? Will the Prison Service also provide additional staffing resources to manage these prisoners, to ensure outcomes for the rest of the prison population are not negatively affected?
Response
HMP Belmarsh’s role in serving the Central Criminal Court and holding category A prisoners inevitably brings with it a cohort of high-profile prisoners. The prison has managed this cohort over many years in various locations and not limited solely to the healthcare department. In each case, individual prisoner risks and needs are considered and the Governor is able to manage their location in accordance with the assessment of the local team and relevant stakeholders. High-profile prisoners are managed across the Long Term and High Security Estate (LTHSE) and HMP Belmarsh is not the sole or default allocation for this cohort. HMP Belmarsh continues to manage a small number of high-profile prisoners, and it is recognised their presence can place additional pressure on resources and impact the wider regime. The Governor works closely with the LTHSE Population Management teams to ensure that allocation decisions are risk-assessed and proportionate. Where possible, alternative locations are considered to avoid placing these individuals in the Healthcare Centre’s In-Patient Unit, which is reserved for those with acute clinical needs. Where the use of those facilities is required, additional resources are deployed on a temporary basis to ensure safety and stability is maintained.
HMPPS In progress
7 Will the Prison Service look at ways to mitigate the significant cuts in the education budget? Repeated
Response
HMPPS can confirm that there have been no cuts to the overall national prison education budget. However, the cost of delivering high-quality education has risen significantly in recent years, and while the budget has increased, it has not kept pace with rising costs. Consequently, some reductions in the volume of Core Education delivered have been necessary from October 2025. HMPPS anticipates a national reduction in delivery volume of around 20-25%, although this is subject to final analysis. A revised funding formula has been applied to ensure fair allocation based on prison population and regional cost differences. This redistribution means that some prisons will see greater delivery reductions, while others will see increases. This delivery reduction applies only to Core Education contracts and does not affect other education services such as libraries, careers advice, distance learning or vocational training delivered through industries and workshops. HMPPS is also investing in digital infrastructure, new assessment tools, and specialist staff to ensure that every pound spent delivers the greatest possible impact for learners. The Prison Education Dynamic Purchasing System also remains available to Governors to commission provision to meet the needs of their local prisoner cohort. HMPPS’ priority is to protect the quality of provision and focus on the most effective interventions. The new Prisoner Education Service contracts set clearer expectations for screening and assessment and offer support for learners with additional learning needs. New digital systems will also expand access to secure online education content; reduce repeated assessments; and improve recording of previous achievements and tracking of learners’ progress. It is also important that prisons continue to plan their curriculum based on careful analysis of their population’s needs, and that ongoing efforts are made to improve attendance and allocations to ensure learners can gain the maximum benefit from the provision available.

8 Will the Prison Service look at ways of providing a technological solution, such as computer tablets, to assist in translations for foreign national prisoners with limited English, particularly in a healthcare setting?
Response
HMPPS will be delivering a 9-month pilot of an Artificial Intelligence-powered translation tool. The proof of concept took place in eight prisons and was deemed to be very successful. The pilot will cover 30-40 prisons and HMP Belmarsh has been invited to take part. Following a successful pilot, HMPPS will need to determine if this can be taken forward nationally. A start date for the pilot has not been set but it is envisaged this may commence by April 2026 and run for six months. Whilst it will not replace The Big Word service for legal translations, it is hoped it will become an everyday, easily accessible translation service tool in prisons to aid those whose first language is not English.
