Summary

Summary written by this site (AI-generated)
HMP Millsike, a newly opened Category C prison run by Mitie Care & Custody, experienced a chaotic first year due to a reduced mobilisation period, design flaws, and an inexperienced and short-staffed workforce. Despite an interim Director's efforts leading to improved stability and staff morale, significant challenges persist with staffing, unpredictable regimes, and the prevalence of illicit items. The Board escalated concerns to the Prisons Minister regarding the unacceptable impact on prisoners and systemic issues with new prison openings.

Positive findings

Summary written by this site (AI-generated)
The Board is pleased to note a significant improvement in staff morale since the arrival of the new Director and that some improvements have been observed by the end of the reporting year. Prisoner-on-staff assaults dropped towards the end of the year, and weekly Use of Force scrutiny meetings have been introduced. The Board welcomes additional resources for property management. The library is a positive, inspirational, and enthusiastic place, and over 100 education courses and 340 vocational courses were successfully completed. The number of work and education places has increased, and staff and prisoners are being treated with respect. The new arrangements for visits are preferred by all prisoners, and the Fixed Term Recall 56 process was managed well. Rule 45 boards have been rectified and adjudications are fair.

Recommendations were extracted from the report by AI, and responses and their status from the ministerial response by AI. Each recommendation shows whether its wording has been checked against the report.

Recommendation 1

Addressee: Ministry of Justice · Topic: Safety · Repeated from a previous year

Recommendation (the Board's words)
The Board continues to be concerned that new prisons are being opened knowing that it will take two or three years for them to stabilise, with significant implications for the safety and humane treatment of prisoners during that period. This concern is further exacerbated when prisons are built in remote locations, where recruitment and retention challenges can be particularly acute. At what point will this be recognised as unacceptable, and what steps are being taken to ensure that more effective arrangements are put in place before new prisons open?
Government response (as published)
The Prisons Minister stated: 'Our experience from other prison openings is that it can take up to four years to meet its full potential, but during this period they should maintain stability and be making incremental improvements.' The Minister also acknowledged the compressed mobilisation but cited unprecedented demand for prison places. The Minister stated that the issue of vetting is being addressed.

Recommendation 2

Addressee: Ministry of Justice · Topic: Staffing

Recommendation (the Board's words)
The Board is concerned about delays in the vetting process, which are affecting the recruitment of IMB members, as well as staffing across all organisations working at HMP Millsike. What action is being taken to address these delays, and by when does the Minister expect vetting times to return to a level that no longer hinders recruitment and the effective operation of the prison?
Government response (as published)
The Prisons Minister stated: 'I can assure the IMB that the issue of vetting is being addressed.'

Recommendation 3

Addressee: HMPPS · Topic: Estate

Recommendation (the Board's words)
Despite the fact that design faults had been highlighted following the builds at HMP Fosse Way and HMP Five Wells, no changes were made to the design at HMP Millsike. Whilst the Board was informed that a ‘lessons learnt’ exercise was taking place in 2025 (and provided some limited input), no details have been received of the outcome Have any changes been made, or are any changes planned, to the design of future prison builds, including the next new prison being built by the Prison Service?

Recommendation 4

Addressee: HMPPS · Topic: Safety

Recommendation (the Board's words)
Given the fact that it was clear to the Board very early on that the mobilisation team had not completed all the work required before the prison was opened, why wasn’t the opening postponed? Whilst the Board was aware of the capacity problems in the prison estate at that time, opening the prison at that time resulted in prisoners being treated inhumanely, in our view.
Government response (as published)
Lord Timpson stated: 'I fully acknowledge that the mobilisation for HMP Millsike was compressed... However, the MoJ was facing unprecedented demand for prison places... There was a significant risk that postponing the opening could have worsened the overcrowding crisis.'

Recommendation 5

Addressee: HMPPS · Topic: Other

Recommendation (the Board's words)
The Board is concerned about the impact of the continued use of improvement notices. In the Board's view, senior leaders and managers are focusing on meeting action plan requirements rather than embedding stable day-to-day operations, which is contributing to a number of the issues raised in this report. How will the Prison Service ensure that improvement requirements support, rather than hinder, the long-term stability and development of new prisons?

Recommendation 6

Addressee: HMPPS · Topic: Staffing

Recommendation (the Board's words)
How will the Prison Service ensure that HMP Millsike has sufficient time to recruit, retain and train staff, and establish effective resettlement services, before increasing capacity further, particularly given the implications for the Mitie Care & Custody contract?
Government response (as published)
Lord Timpson stated: 'Mitie has committed to ensuring that the current regime can be maintained as the prison continues to populate and that further regime enhancements will be implemented only once sufficient staff are in place.'

Recommendation 7

Addressee: HMPPS · Topic: Safety

Recommendation (the Board's words)
How is the Prison Service working with Mitie Care & Custody to balance commercial considerations with the safe ramp-up of the prison, and to ensure that prisoners are treated humanely throughout this process?
Government response (as published)
Lord Timpson stated: 'HMPPS will continue to work closely with Mitie to ensure that the ramp-up of the prison is managed safely and humanely.'

Recommendation 8

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

Recommendation (the Board's words)
The Board remains concerned about delays in the vetting process, which appear to be affecting both the recruitment of IMB members and staffing across organisations working at HMP Millsike. Could you the Prison Service provide an update on whether any steps are being taken to improve the situation, particularly given the Ministry of Justice’s contractual six-week timeframe for the vetting of Millsike staff?
Government response (as published)
Lord Timpson stated: 'HMPPS remains committed to reducing the current delays in vetting and returning to the contractual six-week timeframe.'

Recommendation 9

Addressee: HMPPS · Topic: Mental Health

Recommendation (the Board's words)
The Board is concerned that the service level agreement between the Samaritans and HMPPS for the delivery of Listener training does not include private prisons. This has resulted in a significant delay in the deployment of Listeners at HMP Millsike, which the Board finds unacceptable. Why are private prisons excluded from these arrangements, and what action will be taken to ensure timely access to Listener training in future?
Government response (as published)
Lord Timpson stated: 'I am pleased to inform you that HMPPS and Samaritans have agreed on a way forward to ensure that private prisons are included in the Listener scheme.'

Recommendation 10

Addressee: HMPPS · Topic: Safety

Recommendation (the Board's words)
When planning new prisons, how is consideration being given to the implementation of the Crime in Prison Referral Agreement, given concerns that the current process may present particular challenges for private prisons?
Government response (as published)
Lord Timpson acknowledged concerns regarding the CiPRA for private prisons and stated HMPPS is working with providers.
