Irp inspection of HMP Pentonville (2026-03-16)
Pentonville is a historic, reception prison in North London that held 1,189 men at the time of this inspection. It is never an easy jail to run, with overcrowded cells, crumbling infrastructure and a fast-changing population that includes many men who are mentally ill, addicted to drugs and homeless, or who are involved with criminal gangs. At this inspection, however, we found a prison that had seriously deteriorated, with scores of poor in our healthy prison assessments for safety, purposeful activity and preparation for release, and not sufficiently good for respect. As a result of the very worrying findings, I issued an Urgent Notification to the Secretary of State. The treatment of new arrivals to the jail was completely inadequate; prisoners were placed in ill-equipped cells without some basic items such as bedding, pillows or cutlery. Due to the national population pressures, some men spent their first night in the prison housed not on the induction wing, but elsewhere in the jail where staff could not tell us who they were or which cell they were in. In our survey, 44% of prisoners said they felt unsafe at the time of the inspection, the highest number in any reception prison during my time as Chief Inspector. The care for some of the most vulnerable was appalling and so far in 2025 three prisoners had killed themselves. Support for those who were at risk of self-harm or suicide was cursory at best and we found staff who were supposed to be looking after men on constant watch asleep, reading or entirely absent. Many of the wings at Pentonville were chaotic and noisy with lots of shouting from both staff and prisoners. Levels of violence were high, often fuelled by the ingress of drugs into the jail, and inspectors frequently smelt cannabis on the wings. Relationships between prisoners and staff were often poor and prisoners complained that staff seemed to be indifferent to them or their needs. While there were many dedicated staff members at the jail, inspectors witnessed an apparent lack of care from too many officers. The ineffective allocations system meant that many jobs or education places were not filled, meaning that the vast majority of prisoners spent more than 22 hours a day locked in their cells. Staff on one wing were unable to account for the whereabouts of their prisoners during the working day; symptomatic of a prison in disarray. Attendance at education was poor with many prisoners failing to turn up to their lessons. For a few men, there were some activities, such as bike maintenance, that were designed to help them find work on leaving the jail. Overall, the numbers getting into work on release was very low. There were some more positive findings in this inspection. A dedicated health care team managed to deliver a good service, with some particularly good levels of care for some very unwell men on the inpatient unit. The incentivised substance free living (ISFL) unit was better than we often see, with men given good support to address their addiction. The well-regarded Time for Change programme, run by an experienced custody manager, supported some of the younger men at Pentonville. Inspectors were shocked to find that staff were consistently failing to calculate prisoners’ sentence length correctly. This is a fundamentally important task to make sure that prisoners are released on the correct day. At Pentonville, this work was not being done accurately or in a timely fashion, meaning that many men had been kept in the prison after their sentence should have ended. While we believe that most had only been released a day late, there may have been others who were held for longer. In this report we describe comprehensive failures by leaders to make sure that there was effective oversight and management of some of the basic operations of a reception prison. It will take support and investment from the prison service to turn round this this
4.1 Reception and induction Four different Governors headed the early days in custody (EDIC) wing during the reporting year, so some fresh approaches were short-lived. Reception processed over 22,000 movements in and out of the prison. Reception staff were observed to treat new arrivals with respect, compassion and efficiency. When asked by Board members, prisoners generally said they were treated with respect. New arrivals were interviewed by a trained officer, but a lack of privacy may have inhibited frankness, which contributes to risk assessment. Men were also interviewed by a nurse and referred, if necessary, to the GP who was on duty each evening. Prison orderlies (trusted prisoners who take on work to provide services that contribute to the running of the prison) were a cheerful presence and gave the new arrivals kit and an induction booklet and served a hot meal. Prisoners arriving on transfer often brought several bags of property and had to choose one, which was searched by prison officers, emptying it on to the floor, before the prisoner could take it to his cell. There was a body scanner in reception but still no scanner for property, which the Board believes could make the process more respectful and quicker. Despite the emphasis on decency by the Governor, the standard of first-night cells slipped. Random checks by the Board (or a Governor) sometimes found essentials missing, such as a pillow, blanket or kettle and, occasionally, a cell was filthy. Housekeeping [...]
5.1 Accommodation, food Accommodation Pentonville was built in 1842 to accommodate 540 prisoners in single cells. By the end of March 2025, the unlock figure was 1180, with two men living in cells originally built for a single prisoner. These 12 x 8ft cells had a bunk bed, a table and a chair, although there was not always adequate furniture for both occupants of a shared cell. Cells had a toilet, but not all had effective screening. Furthermore, the crumbling fabric of the building was susceptible to continual infestations of mice, cockroaches, flies and rats. This was evidenced in the shutting down of the kitchens in April 2024 for 14 weeks due to a rat infestation. Blitzes by a pest-control company provided only temporary respite with rats frequently being found behind boxed-in pipework in the cells. Although in-cell TVs and phones alleviated boredom and allowed contact with the outside world, the potential health hazard of living with vermin, together with the lack of privacy and cramped conditions, are not decent or humane. Major problems with the fabric and infrastructure of the prison were evidenced in the regular applications from prisoners to the Board relating to the antiquated heating and plumbing systems. Problems with plumbing, drainage, heating and hot water occurred regularly, affecting personal hygiene. Some of the higher landings experienced intolerable temperatures in the summer, made worse by new windows that did not allow air flow. Several showers had [...]
Offender management unit (OMU) In its three previous annual reports, the Board has been critical of the OMU. This reporting year, 14% of all applications to the Board related to OMU services, similar to the previous year. Continuing from last year, there have been a series of different government-imposed measures, which have placed substantially increased demands on the OMU. These were implemented to manage prison overcrowding by releasing some prisoners early. These initiatives are extremely complex and require additional training of already overburdened staff. This inevitably resulted in a lack of time to deal with the routine services provided by the team. In addition, due to the high number of prisoners on remand, there were 20-35 immediate releases each week. These required extensive, rapid and accurate checks and resulted in a backlog of sentence calculations and transfers for other prisoners. All of these are matters of extreme frustration and anxiety for prisoners. By early March, there were between 60 and 70 sentence calculations outstanding. It also meant that there was no resumption of wing-based OMU clinics, which happened for a brief period during the last reporting year and were much appreciated by the prisoners. The following measures have been introduced to support the OMU: • since December, there have been two heads of the OMU, one operational and one non-operational. The operational appointment was initially temporary, with a permanent appointment made by [...]
From the Board’s observations, the education programme in Pentonville is a great resource and is appreciated by the prisoners, with the courses and the teachers receiving praise. An internal audit by the provider, Novus, reported in March 2025 that: ‘Learners’ behaviour and attitudes across the department are exceptional… reflecting high expectations set by leaders and managers.’ Nevertheless, throughout the year, late unlocking by wing staff remained a frustration, as this meant attendance and punctuality were erratic. In December, a payment was introduced for taking the basic skills assessment (BSA), usually on day two in the prison and a requirement for getting a job or participation in education, but this ended on 31 March. This was unfortunate, as it appeared to have a positive effect. In February, when the scheme was fully embedded, induction attendance was 94% and education attendance was 60%. This fell in March, possibly because prisoners knew the incentive was due to be stopped. A wide variety of courses and activities was delivered, including the following: Customer service Fire Safety Duke of Edinburgh Bronze and Silver Awareness Awards Food safety Peer Mentoring Vocalise with the University of Law Painting and Business Enterprise Distance Learning with The Open Decorating University Barbering Maths Criminology Level 3 with Westminster University Writing Group E nglish Business with Urban Lawyers Radio Production ESOL Public speaking with John Bercow The library [...]
1.1 HMP Pentonville in North London is one of the oldest prisons in the country. It received its first prisoners in 1842 and was designed to hold 520 people in single cells. Today, it is a category B reception prison, holding over 1,100 remand and convicted male prisoners aged 18 and over. 1.2 At our previous inspections of HMP Pentonville in 2019 and 2022 we made the following judgements about outcomes for prisoners. Figure 1: HMP Pentonville healthy prison outcomes in 2019 and 2022 Good Reasonably good Not sufficiently good Poor
HMP Pentonville in north London is one the oldest prisons in the country. It received its first prisoners in 1842 and was designed to hold 520 people in single cells. In recent times, it has routinely been one of most challenging and troubled prisons, with a succession of poor inspections. Our last full inspection in 2019 was no exception to this sorry history, but at our scrutiny visit in 2020 we saw evidence of fragile progress. At this inspection, the promise of improvements had been realised in part, but many serious concerns remained, including some fundamental weaknesses in offender management and provision of activities. Safety had improved, with much reduced violence, a well-run segregation unit and better governance of force. Nevertheless, there was still a high rate of illicit drug use, there had been seven self-inflicted deaths since 2019 and care for those at risk of self-harm was not yet good enough. In addition, time out of cell and constructive activities were seen, at least in the short-term, as acceptable collateral damage in the drive to improve safety. This approach did not sufficiently recognise that an institution that promotes safety is also one that considers the impact of lengthy periods of lock-up on mental health and on prisoners’ chances of being released into society with the skills that might help them to stay out of trouble. There were other indications of a prison that was headed in the right direction. For example, it was positive to see the ambitious long-term vision represented by the plan for a new unit intended to care for neurodiverse prisoners, and the unusually good work that was done to support young offenders. Leaders had also taken steps to address deep-rooted problems in the staff culture and capability even if results were, so far, limited. However, Pentonville has had more false dawns than most prisons. It is an indication of the profound problems it faces that, despite the improvements that were being made and the considerable dedication and capability of its leaders, outcomes for prisoners were still not good enough in any of our healthy prison tests. This report gives the reasons for these judgements in some detail, but one concern is worthy of particular mention. Pentonville remains a cramped early Victorian relic, with claustrophobic wings and a crumbling physical infrastructure that require constant repair and refurbishment to meet the most basic standards of decency. The prison currently holds over 1,100 prisoners and this number is continuing to rise. While it has added some new living units, the increased capacity has come about largely by placing two people in cells designed for one. Over 60% of prisoners are in overcrowded cells and the prison’s footprint is not markedly different from when it held fewer than half the current number. It is hard to avoid the conclusion that Pentonville cannot safely and decently care for its current population, as illustrated, for example, by the high number of prisoners with mental health needs who could not get prompt appointments, and the wholly inadequate access to purposeful activity. If the prison is to make further progress, national leaders need to accept the limitations of an establishment that has to work harder than most to battle through its entrenched problems.

Urgent Notification Where HM Chief Inspector of Prisons identifies significant concerns on the treatment and conditions of those detained in prisons, he may write to the Secretary of State within seven calendar days of the end of the inspection, providing notification of the significant concerns and the reasons for those concerns. See: https://www.justiceinspectorates.gov.uk/hmiprisons/about-hmi-prisons/urgent- notifications/ About this report HMP Pentonville 5 About this report A1 Her Majesty’s Inspectorate of Prisons (HMI Prisons) is an independent, statutory organisation which reports on the treatment and conditions of those detained in prisons, young offender institutions, secure training centres, immigration detention facilities, police and court custody and military detention. A2 All visits carried out by HM Inspectorate of Prisons contribute to the UK’s response to its international obligations under the Optional Protocol to the UN Convention against Torture and other Cruel, Inhuman or Degrading Treatment or Punishment (OPCAT). OPCAT requires that all places of detention are visited regularly by independent bodies – known as the National Preventive Mechanism (NPM) – which monitor the treatment of and conditions for detainees. HM Inspectorate of Prisons is one of several bodies making up the NPM in the UK. A3 Independent reviews of progress (IRPs) are a new type of visit designed to improve accountability to ministers about the progress prisons make towards achieving HM Inspectorate of Prisons’ recommendations in between inspections. IRPs will take place at the discretion of the Chief Inspector when a full inspection suggests the prison would benefit from additional scrutiny, and will focus on a limited number of the recommendations made at the inspection. IRPs will therefore not result in assessments against our healthy prison tests. HM Inspectorate of Prisons’ healthy prison tests are safety, respect, purposeful activity and rehabilitation and release planning. For more information see our website: https://www.justiceinspectorates.gov.uk/hmiprisons/our-expectations/ A4 The aims of IRPs are to: - assess progress against selected key recommendations - support improvement - identify any emerging difficulties or lack of progress at an early stage - assess the sufficiency of the leadership and management response to our main concerns at the full inspection. A5 This report contains a summary from the Chief Inspector and a brief record of our findings in relation to each recommendation we have followed up. The reader may find it helpful to refer to the report of the full inspection, carried out in April 2019 for further detail on the original findings: https://www.justiceinspectorates.gov.
