Summary

Summary written by this site (AI-generated)
HMP Thameside, a busy local Category B/C prison, faces significant challenges despite efforts to maintain safety. Key concerns include persistent issues with healthcare provision, delays in mental health transfers, and inadequate resettlement services leading to poor outcomes for prisoners. While there have been improvements in staffing levels and specific unit regimes, the Board remains concerned about the quality of ACCT documentation, inconsistent application of incentives, and late court returns.

Positive findings

Summary written by this site (AI-generated)
The IMB commends the increased staffing and regime improvements on houseblock wings and specialized units (IPU, CSU, IDTS, EDC). Positive steps have been taken to address CMS issues, and the chaplaincy, E&D, neurodiversity, library, Catch 22, Shannon Trust, and Families First teams continue to provide excellent services. The introduction of EDiC meetings and improved communication with healthcare providers are welcomed, as is the hard work of the gym team and increased time out of cell on reception wings.

Recommendation 1

Response: In progress

Addressee: Other, minister · Topic: Mental Health · Repeated from a previous year

Recommendation (the Board's words)
While the proportion of transfers to external mental health facilities has improved this year, there were still too many patients (two-thirds) transferred beyond the 28-day limit. What concrete steps will the Minister take to address this issue and within what timeline?
Government response (as published)
I appreciate the Board’s ongoing concerns about access to secure mental health facilities. While it is encouraging that the proportion of timely transfers has improved, it is unacceptable that two-thirds of patients were transferred beyond the 28-day limit. As you will be aware, the Mental Health Bill introduces a 28-day timeframe for transfers, placing NHS England’s Best Practice guidance on a statutory footing. The Bill is currently in its final stages having gone through all three readings in both the House of Lords and House of Commons. The Ministry of Justice is working closely with the Department of Health and Social Care, NHS England, the Welsh Government, the Home Office and the Youth Custody Service to create and to deliver operational improvements within 18–24 months following Royal Assent.

Recommendation 2

Response: In progress

Addressee: Other, minister · Topic: Resettlement · Repeated from a previous year

Recommendation (the Board's words)
The lack of probation and community support for all prisoners means that they are more likely to return to prison. What measures is the Minister taking to address the shortfalls of probation and community support in the London area?
Government response (as published)
I acknowledge the Board’s repeated concerns regarding probation and community support. Recruitment and retention remain a priority for the Probation Service, which has seen a 20% increase in staffing since unification in June 2021. Between June 2024 and June 2025, the London region saw a 4% increase in full-time equivalent Probation Officers, with 24 additional staff recruited, and it continues to prioritise recruitment efforts. These increases form part of a broader strategy to strengthen probation services, we have committed to onboarding a further 1,300 probation trainees in 2025/26 to help ensure that individuals leaving custody receive the necessary support to reintegrate successfully into the community.
Probation and community resources

Recommendation 3

Response: In progress

Addressee: Other, minister · Topic: Resettlement · Repeated from a previous year

Recommendation (the Board's words)
Probation support for remand prisoners, in particular, remains inadequate, despite the promised investment. The increase in the remand population has not been matched with a sufficient increase in resettlement resources, to ensure that the majority of prisoners get the support they need. What specific, measurable steps will the Minister take to increase probation support and ensure adequate resettlement for all remand prisoners?
Government response (as published)
I recognise the particular challenges faced by remand prisoners. The increase in the remand population has placed additional pressure on resettlement resources. Serco is working with HM Prison and Probation Service (HMPPS) to align resources accordingly, and while previous funding requests for resettlement and remand support were declined, discussions remain ongoing. The ID Banking Clerk role is now a full-time provision, with Catch22 continuing to support structured interventions. The absence of Bail Information Officers has been raised and is being addressed to ensure that remand prisoners receive the support they need.

Recommendation 4

Response: In progress

Addressee: HMPPS · Topic: Resettlement · Repeated from a previous year

Recommendation (the Board's words)
Probation and community resources remain inadequate, despite promised investment – see above, ‘to the Minister’.

Recommendation 5

Response: In progress

Addressee: HMPPS · Topic: Resettlement · Repeated from a previous year

Recommendation (the Board's words)
Inaccurate data on BCS2s and BCS3s was being logged continuously on the pre-release team’s systems from July 2024 for 11 months, without any investigation as to its validity or the performance of the team (see 7.5). Is the team required to regularly submit data to either the Probation Service or HMPPS on the completion rate of these and other mandatory tasks?
Government response (as published)
Data Accuracy and Quality Assurance in Pre-Release Teams: There is currently no national infrastructure for reporting the work undertaken by pre-release teams, which has been identified as a gap. In response, London Regional Probation has developed a local reporting system that relies on managers and staff to log completed tasks. Data is submitted monthly and managed by the administrative team. HMPPS has been involved in discussions to strengthen quality assurance processes with interventions now in place to ensure improvement and provision for escalation of corrective actions where needed. Locally, the Head of Offender Management Delivery attends monthly Senior Leadership Team meetings to review and discuss team performance.

Recommendation 6

Response: In progress

Addressee: HMPPS · Topic: Resettlement · Repeated from a previous year

Recommendation (the Board's words)
The processes followed by the resettlement team to support prisoners in finding accommodation on release remain inadequate, resulting in too many men leaving the prison homeless. How will the Prison Service improve the processes?
Government response (as published)
Homelessness on Release: We acknowledge and share the Board’s ongoing concern regarding homelessness upon release, which remains a significant challenge. The Strategic Housing Specialist at Thameside engages in five borough panels to plan interventions ahead of release. Barriers to commissioned rehabilitative services (CRS) referrals include limited access to prisoners and facilities and late referrals. To address these issues, the ‘Right First Time’ briefing and Good Industry Practice document were introduced. New contracts for CRS are being procured, effective Spring 2027, to better support housing and employment outcomes. Locally, Catch22, Probation, and the Pre-Release Team coordinate referrals to St Mungo’s and CAS3, with high-risk cases directed to Approved Premises. The Strategic Housing Lead collates outcome data and chairs bi-monthly Reducing Reoffending meetings to keep this under review and seek further improvements.

Recommendation 7

Response: In progress

Addressee: HMPPS · Topic: Resettlement · Repeated from a previous year

Recommendation (the Board's words)
There is a lack of coordination and effective oversight of the various agencies providing resettlement services. This, along with continuing recruitment issues, results in prisoners in Thameside not getting the resettlement support they need. What will the Prison Service do to address this issue?
Government response (as published)
Coordination and Oversight of Resettlement Services: Resettlement activity in London is overseen by a dedicated Head and Deputy Head of Service; an exception adopted three years ago to address specific regional challenges. Pre-release information sharing meetings operate across all London prisons alongside Interdepartmental Risk Management Meetings (IRMMs) to ensure pre-release planning for every sentenced prisoner and that any actions are identified and overseen by custody based Senior Probation Officers. A deficit remains in the offer for remand prisoners, but the effectiveness of an immediate release pilot at Wandsworth has been recognised and may be rolled out nationally. Locally, fortnightly pre-release meetings and monthly IRMMs include all relevant agencies to ensure join up.

Recommendation 8

Response: Noted

Addressee: HMPPS · Topic: Regime · Repeated from a previous year

Recommendation (the Board's words)
While the Board acknowledges the measures taken to clear the backlog of court cases, this has resulted in vans regularly arriving at the prison after the lock out time of 8.00 pm. (see table 1, Annexe C). What actions will the Prison Service take in conjunction with the Prisoner Escort and Custody Service to minimise this?
Government response (as published)
Late Court Sittings and Reception Capacity: Prisoners are allocated from court to prison based on pre-agreed alignments, irrespective of the time court proceedings conclude. This approach ensures a balanced distribution of remand prisoners and places individuals in the most appropriate establishment aligned to their originating court. Any changes to this system would disrupt the existing logistical framework and likely result in delays, negatively affecting court service delivery including increased courtroom wait times due to unaligned prisoner movements. We recognise the need for flexibility and, where necessary, HMP Thameside collaborates with healthcare providers to accommodate late arrivals and ensure prisoner needs are met. Practice Plus Group has reviewed its reception resources and implemented a flexible plan to support efficient healthcare screening. Low-risk or non-Integrated Drug Treatment System prisoners are fast-tracked through reception, ensuring only those requiring clinical attention remain. This reduces wait times and addresses first-night concerns. The Serco Reception Officer team operates independently and is well-versed in reception procedures. As part of the broader site Detail Review, it has been identified that the reception team roster should be adjusted to include later finishes to better manage late arrivals. In the interim, HMP Thameside continues to monitor staff sickness and absence, promote employee wellbeing across the site, and maintain daily engagement between senior management and staff to address any concerns.

Recommendation 9

Response: In progress

Addressee: HMPPS · Topic: Other

Recommendation (the Board's words)
In order to carry out its statutory duties, the IMB is entitled to be given data from the agencies contracted by HMPPS who carry out resettlement work. This includes the number of prisoners receiving support, achievement of targets and staffing levels. When asked for this data, some teams ignored the Board’s repeated requests, while others had to get permission from managers (causing unnecessary delays). Will HMPPS please confirm with the contracted agencies that they can (and should) provide the IMB with data on request?
Government response (as published)
IMB Access to Resettlement Data: The Statutory Role of the IMB document will be shared with all staff and stakeholders to promote awareness of the IMB’s role and reporting requirements. The Director at HMP Thameside remains committed to resolving access to information requests and supporting appropriate escalation where necessary.

Recommendation 10

Response: In progress

Addressee: NHS / Healthcare Provider · Topic: Mental Health · Repeated from a previous year

Recommendation
NHS England should outline what is being done to increase capacity for mental health transfers from prison to hospital, particularly in light of the proposed statutory 28-day time limit.
Government response (as published)
I note that you have also raised a query for NHS England around its capacity to support this. NHS England is improving data collection and monitoring, reviewing referral processes, and providing training to prison staff. The newly established Mental Health and Justice Strategic Advisory Group will provide clinical leadership and oversight across the pathway, helping to identify and address common causes of delay. A dedicated resource has also been assigned to scrutinise data and escalate breaches of the 28-day target directly with trusts and Integrated Care Boards (ICBs). In addition, a further £42 million recurrent investment from 2024/25 will support ICBs in recommissioning inpatient care aligned with local therapeutic models. These steps reflect our shared commitment to ensuring that people in custody with severe mental illness receive timely and appropriate care.

Recommendation 11

Addressee: Governor / Director · Topic: Safety · Repeated from a previous year

Recommendation
The Director should ensure that processes are in place for routine regular audits of ACCT documentation and that all staff are aware of their responsibilities in completing these documents.
Government response (as published)
Concerns remain that 80% of documents continue to fall below an acceptable standard in the prison’s own audits and that regular audits have not taken place for much of the year.

Wording differs from source

Recommendation 12

Addressee: Governor / Director · Topic: Regime · Repeated from a previous year

Recommendation 13

Addressee: Governor / Director · Topic: Regime · Repeated from a previous year

Recommendation (the Board's words)
What measures can the Director take to improve prisoners’ confidence in the incentives system so that it is more consistently applied and that quality assurance is routinely carried out?
Government response (as published)
Some improvement has been noted in relation to canteen issues, but no change to property processes (see above). The Board understands that a review of the incentives process will be carried out.

Key concerns 25 items

Key concerns were extracted from the report text by an AI model.

Key concern 1

Safety · Repeated from a previous year

However, the Board remains concerned about assessment, care in custody and teamwork (ACCT) documentation (used to support prisoners who are at risk of self-harm and suicide) and the poor ratio between overall and proven adjudications.

Key concern 2

Safety

The lack of a quality assurance audit for Challenge, Support and Intervention Plans (CSIPs) has been a concern.

Key concern 3

Mental Health · Repeated from a previous year

There is still no effective Listener scheme (whereby prisoners are trained by the Samaritans to offer confidential emotional support to other prisoners) and the alternative provision has significant limitations.

Key concern 4

Safety

Funding for an effective restorative justice post was discontinued.

Key concern 5

Regime/Time Out of Cell · Repeated from a previous year

Although the prison’s policies and processes are designed to be fair, there are still some areas where inadequate management results in unfairness, in the Board’s view. For example, the handling of prisoner property requires a major overhaul, and the administration of the incentives policy requires management oversight to ensure a more consistent approach.

Key concern 6

Healthcare · Repeated from a previous year

Poor administration and management of healthcare complaints and clinic bookings, long waiting times, delays and omissions in medication provision, and concerns regarding safe medication administration.

Key concern 7

Healthcare · Repeated from a previous year

Suboptimal healthcare staffing levels, including an absence of consistent senior leadership, and inconsistent coordination, attendance, and reporting of healthcare meetings.

Key concern 8

Mental Health · Repeated from a previous year

Continued delays for mental health transfers to external facilities, with too many patients transferred beyond the 28-day limit.

Key concern 9

Resettlement/Release

Insufficient information and resources for visitors, both on the website and in the visitors’ centre, regarding visits, ID, property hand-ins, parking, and appropriate clothing.

Key concern 10

Resettlement/Release

Lack of secure storage for visitor property, despite repeated assurances.

Key concern 11

Resettlement/Release · Repeated from a previous year

Serious concerns regarding the adequacy of resettlement services for prisoners, especially the probation and pre-release teams.

Key concern 12

Other

Delayed or lack of responses from some resettlement agencies to requests for data from the Board.

Key concern 13

Resettlement/Release · Repeated from a previous year

The lack of probation and community support for all prisoners means that they are more likely to return to prison.

Key concern 14

Resettlement/Release · Repeated from a previous year

Inadequate probation support for remand prisoners, despite promised investment, and insufficient increase in resettlement resources to match the significant increase in the remand population.

Key concern 15

Resettlement/Release · Repeated from a previous year

Inaccurate data on BCS2s and BCS3s was being logged continuously on the pre-release team’s systems from July 2024 for 11 months, without any investigation as to its validity or the performance of the team (see 7.5).

Key concern 16

Resettlement/Release · Repeated from a previous year

The processes followed by the resettlement team to support prisoners in finding accommodation on release remain inadequate, resulting in too many men leaving the prison homeless.

Key concern 17

Resettlement/Release · Repeated from a previous year

Lack of coordination and effective oversight of the various agencies providing resettlement services, coupled with continuing recruitment issues, prevents prisoners from getting the resettlement support they need.

Key concern 18

Regime/Time Out of Cell · Repeated from a previous year

Court vans regularly arriving at the prison after the lock-out time of 8.00 pm, impacting prisoner and staff welfare.

Key concern 19

Other

In order to carry out its statutory duties, the IMB is entitled to be given data from the agencies contracted by HMPPS who carry out resettlement work. This includes the number of prisoners receiving support, achievement of targets and staffing levels. When asked for this data, some teams ignored the Board’s repeated requests, while others had to get permission from managers (causing unnecessary delays). Will HMPPS please confirm with the contracted agencies that they can (and should) provide the IMB with data on request?

Key concern 20

Safety

Over the reporting year, the Board’s monitoring of both houseblocks, as well as the CSU and IPU, has noted broken or faulty observation panels in cell doors. This poses a potential risk, especially when the prisoners in these cells are on heightened unlock. In a final report on a death in custody at Thameside, published in May 2025, the PPO found that a broken/faulty observation panel contributed to the death of a prisoner (see 4.2.2).

Key concern 21

Estate/Conditions · Repeated from a previous year

The lift in the gym remains out of use, which means that prisoners with mobility issues are unable to access the cardio room.

Key concern 22

Regime/Time Out of Cell · Repeated from a previous year

This has continued during the current reporting year, although broken/faulty in-cell CMS still occur with depressing frequency. Lack of access to CMS greatly impacts prisoners’ lives, as most of the routine systems and processes in the prison rely on it, e.g, booking visits, ordering canteen and booking gym and library sessions, as well as contacting the various prison departments.

Key concern 23

Estate/Conditions · Repeated from a previous year

Inadequate heating and ventilation system: unfortunately, the building design means little can be done to address this.

Key concern 24

Food/Catering

• Lack of staff supervising the serving of meals. • Lack of appropriate clothing for servery workers. • Food temperature probes either not being available or not being used. • Contamination of halal food with non-halal food, due to misuse or lack of designated utensils and food trays.

Key concern 25

Regime/Time Out of Cell

The Board was saddened to hear that, over the reporting year, there were four instances where prisoners were unable to attend the funerals of a close family member, despite advance authorisations from security and subsequent arrangements made by chaplaincy. The Board understands that in all cases, there was a breakdown of communication on the day between staff who were detailed to facilitate this.
