Key concerns
Positive findings
HMP/YOI Isis experienced a significant increase in violence in 2024, with both prisoner-on-prisoner and staff assaults rising, alongside a worrying over-representation of black prisoners in violence metrics and PAVA use. Key concerns include slow emergency cell bell response times, poor hygiene in living areas, and the holding of mentally unwell prisoners in segregation. Despite these challenges, there have been improvements in educational attainment and some healthcare attendance, though staffing shortages continue to impede a full regime and purposeful activity.

Positive findings
HMP/YOI Isis has shown improvements in several areas, notably in educational attainment where 817 out of 954 prisoners successfully completed courses, achieving an 86% success rate in 2024. Communication between departments was effective in ensuring prisoners on early release schemes completed their education. The induction process has also seen gradual improvements, including a new informative booklet for arrivals. Furthermore, attendance at Friday prayers has significantly improved, and the prison's weekly Use of Force review meeting is commended for its thoroughness and objectivity.
Key concerns
Safety
Violence in the prison increased markedly again this year. Data presented at the monthly safety, equalities and use of force meeting show 419 incidents of prisoner assaults and fights in 2024, compared with 319 recorded in 2023, an increase of 31%. Assaults on staff increased from 161 in 2023 to 207 in 2024, up 28%.
Equality/Diversity
The Board was concerned about the over-representation of black prisoners in these figures and undertook further analysis of the use of force data in “large” incidents involving four or more prisoners... This analysis provides a rationale for the over-representation, but we feel further investigation of the over-representation of black prisoners in violence and use of force, especially the significant over-representation in those affected by PAVA, is required, and the Board will be monitoring this more closely over the next year.
Safety
Repeated
IMB analysis showed that the average and median times to answer cell bells in the house blocks in August was beyond the five minutes required in the Notice to Staff (NTS 53.18) guidance - the most recent we could find. Furthermore, the analysis shows peaks in the times to answer at around 9am and 1pm - coinciding with morning meetings and lunchtime. We are concerned that this puts prisoners at risk if they are unwell or in danger.
Estate/Conditions
Repeated
The general standard of cleanliness of the spurs continued to be of concern. In particular, serveries were often left overnight with dirty pans and remnants of food from the previous day.
Mental Health
The Board remains concerned that prisoners with serious mental health problems were held in the Segregation Unit, often whilst waiting for an appropriate transfer to a specialist hospital, as the prison has no in-patient facility.
Regime/Time Out of Cell
Repeated
The amount of time that prisoners are locked in their cells remains a problem, with prisoners’ time out of cell typically being five hours a day from Monday to Thursday, and at most two and a half hours for the remaining three days. This is far less than the HMIP recommendation that prisoners should have a minimum of 10 hours out of cell each day. The Board was particularly concerned about prisoners who were on separate regimes... These prisoners were only allowed out of their cells when other prisoners were locked up, and so may be out of their cells for as little as 30 minutes a day.
Other
Repeated
Prisoner property remains a concern for the Board. Prisoner complaints about property were, at 28% of all complaints, by far the most common, and 22% (45) of IMB applications concerned property, with over half of them (12%) relating to property during transfer or in another facility.

What is the MoJ strategy for the management of young adults in the prison estate?
Response
I have read your report with care and share your concerns about the rising levels of violence at HMP/YOI Isis, particularly amongst young adult prisoners. HMP/YOI Isis is dual designated, which allows it to hold 18 to 21-year-olds in addition to the older adult population. It is essential that reception prison places are maintained to effectively serve local courts. It is important that this cohort can progress to the next stage prison as designated by the national offender flows, and prisons of all categories designed to hold 18 to 21-year-olds should not routinely refuse to accept them. As HM Prison and Probation Service (HMPPS) continues to navigate through population pressures, SDS40 and other initiatives have provided opportunities to progress prisoners through the system. This includes aiding the rehabilitation and access to the right services for 18 to 21-year-olds in the next stage prisons. |

What plans are there for a strategy that aims to reduce violence among young offenders in the community before they are sentenced, after sentencing and after their sentence is over?
Response
I also recognise your concerns about gang culture and knife crime within our communities as well as our prisons. The Government is taking a number of steps to go ‘upstream’ of the crimes and behaviour that lead to young people committing knife crime and other serious offences. We will intervene earlier to stop young people being drawn into crime, creating a new Young Futures programme with a network of hubs with youth workers, mental health support workers, and careers advisers on hand to support young people’s mental health and avoid them being drawn into crime. Local prevention partnerships will identify young people who could be drawn into violence and intervene. We have begun plans to test and pilot these in 2025/26. We are also legislating through the Crime and Policing Bill to create a new offence of criminal exploitation of children, to go after the gangs who are luring young people into violence and crime. The Mayor of London continues to commission and support a wide variety of programmes across London to reduce violence in the community, with a number specifically focused on those being released from custody or with active involvement in the criminal justice system. This includes the GPS tagging programme for knife crime offenders, which often tags prisoners as they are released from HMP/YOI Isis and has been shown to reduce reoffending post-release. |

How will the Minister allocate the necessary resources for this age group in HMP/YOI Isis?
Response
I appreciate that managing these issues can be resource intensive. In March 2025, HMP/YOI Isis gained staff on detached duty, and this allowed for improved regime delivery as well as increased key work delivery to around 400 sessions per month. Whilst this is still below the target, it is a significant improvement. It is recognised how beneficial improved staffing is in supporting the establishment managing a complex population. As of May 2025, I am pleased to report that the prison was almost fully staffed with the required number of prison officers. In addition, retention rates are improving, and sickness levels have recently significantly improved. |

Does the prison service have reoffending rates for specific prisons and, if not, what will the prison service do to obtain reoffending rates for different prisons?
Response
Subject to satisfactory quality assurance and development, the intention is for the Ministry of Justice to resume the publication of reoffending rates by prison establishment in 2026. |

What research has been done into the reasons why black young men are disproportionately involved in violence including multiple prisoner fights and how can this be disseminated to prisons like HMP/YOI Isis, for whom this is a major factor in the levels of violence?
Repeated
Response
Recent surveys and safe space discussions with young black men revealed that the majority had been exposed to violence during their childhoods. They were more likely to have grown up expecting physical violence as a punishment from their carers. Other opinions given were community issues that have happened outside and continue to affect life inside an establishment. HMP/YOI Isis delivers a trauma informed response approach and many interventions to support young black men. Earlier this year a Use of Force survey on black men was carried out at the prison to deep dive into experiences of young black men in HMP/YOI Isis and an action plan was subsequently created to support this minority group. Interventions such as Belong, Men of Purpose, Changing the Game and Black Heroes Journey are all established in the prison to address the issues faced by black men in and outside prison and help change any patterns. Delivery of ‘Aspire Higher’ a Black Excellence programme to gain life skills such as leadership, teamwork, relationship building, personal development and problem solving has also had a positive impact. There has been a focus on ensuring that there is no disproportionality in the treatment of young black men and forums such as 'Black prisoner experiences' have been held regularly to give prisoners a voice on their perspective and better understand the disproportionality. |

If similar schemes can be expected in the future, how will the MoJ ensure that staff in the prison and probation service are adequately supported such that the prisoners not within the scope of these schemes do not experience a reduction in the support available, due to limited resources being diverted elsewhere?
Response
The impact of capacity-related measures and activity on OMUs has been recognised and the work that has been delivered by OMU staff across the estate has been central to their successful delivery. While there has been an unprecedented pressure, temporary resource uplifts have been made available to prisons to assist with this, including an uplift to recognise extra work on Home Detention Curfew and the provision of incentivised overtime for OMU staff. In addition, a central team has been providing support in completing OASys assessments to support prison OMUs. In response to SDS40, HMPPS has completed a national lessons learned review and this learning will inform the development of any capacity management measures we deploy in future, beginning with those we develop as part of the programme to implement the changes resulting from the Independent Sentencing Review. |
