The requested information, as of 30 June 2026, the latest date for which these statistics are available, has been included as Annex A.

Releases in error have been increasing for several years and are another symptom of the prison system crisis inherited by this Government. On 11 November, the Deputy Prime Minister announced a five-point national action plan to reduce releases in error, which includes strengthening release checks across prisons and an independent review led by Dame Lynne Owens.

Totals for releases in error, including a breakdown by releasing prison (or Prisoner Escort Custody Services), are published each July in the HMPPS Annual Digest, available via HMPPS Annual Digest, April 2024 to March 2025 - GOV.UK(opens in a new tab), and provide data up to March 2025.

The Government is determined to fix the issue of mistaken releases and ensure the public is properly protected.

The requested data is not held centrally and could not be obtained without incurring disproportionate cost.

In the last financial year (FY 23/24) Forward Trust has received £7,401,140 from the Department for prison contracts.

Forward Trust has received £0 for contracts relating to HMP Maidstone, HMPS Huntercombe and HMP Morton Hall in the last financial year.

Prisoners are not permitted to have mobile telephones, and stringent measures are in place to prevent the entry of mobile telephones into establishments.

To provide data on prisoners remaining in custody beyond their sentence date would require a search of individual records, which could not be done without incurring disproportionate cost.

Information on interpretation and translation costs covering the time period specified is not available. Expenditure interpretation and translation in the current financial year to date is shown in the table below. As both types of expenditure are accounted for under the same budget item, it is not possible to provide a further breakdown.

“Drug-related incident” is not a discrete category within the data collected. A variety of different types of incidents could potentially be drug related. It would therefore be necessary to make a detailed search of individual records to establish which incidents could be categorised in that way. This could not be done without incurring disproportionate cost.

Please see the below table showing the number and rate of assaults on staff in HMP (a) Maidstone, (b) Huntercombe and (c) Morton Hall in each of the last five years, together with the rate of assaults on staff across the estate as a whole.

Number and rate per 1,000 prisoners of assaults on staff¹ within prison custody, 2019 to 2023

These figures have been drawn from the HMPPS Incident Reporting System. Care is taken when processing and analysing returns but the detail is subject to the inaccuracies inherent in any large scale recording system. Although shown to the last case, the figures may not be accurate to that level.

(1) Assaults on staff are a subset of all assault incidents. Some assault incidents may be recorded as both a prisoner-on-prisoner assault and an assault on staff.

(2) Rates express the number of incidents per 1,000 prisoners, and give a more reliable indicator of trends than numbers of incidents because they take account of changes in the prison population over time. The rates are calculated by dividing the number of incidents occurring within a twelve-month period by the average prison population at the end of each month within the same period, multiplied by 1,000. The prison population figures are published in Offender Management Statistics Quarterly.

In 2023-24, 23 education courses were provided at HMP Maidstone, 26 at HMP Huntercombe and 48 at HMP Morton Hall.

Data on the cost of providing these courses at HMP Huntercombe and HMP Morton Hall are in the process of validation. Information in relation to HMP Maidstone is not available, as the costs form part of a single budget item covering a number of prisons and cannot be disaggregated.

Courses, such as the ones offered at these sites, are one of many valuable ways in which we can improve rehabilitation and cut reoffending which costs society more than £18 billion per year.

Information on the number of Band 3 prison officers who were on duty in the prison on that day at HMP Huntercombe, HMP Maidstone and HMP Morton Hall on 1 September 2023, together with the reasons for absence, are set out in the table below:

It should be noted that these figures have been drawn from administrative IT systems which, as with any large-scale recording system, are subject to possible errors with data entry and processing.

The figures for those who were on duty in the prison on that day include all staff who attended for all or part of a shift, including any additional-payment shifts and night duties. Those recorded in the category of ‘Other Absences’ can include staff attending medical appointments, and those on restricted duties, phased return, secondment, maternity leave, jury service, official duty, parental leave, suspension or bed watch, as well as any working at a different grade, taking time off in lieu or working remotely.

We have taken a series of measures to increase the prison workforce. Despite a challenging labour market, the 12 months ending 30 June 2023 saw an increase of 701 Full-Time-Equivalent Band 3-5 prison officers. This means we now have 4,000 more prison officers than in March 2017. We are committed to recruiting up to 5,000 prison officers across public and private prisons by the mid-2020s.

We recently increased the pay of the vast majority of frontline officers by 7 per cent. Combined with other pay rises, this means starting pay for prison officers has increased since 2019 from £22,293 to £30,902 (on the basis of a national rate, 37-hour week with unsocial hours) or £23,529 to £32,851 (on the basis of a national rate, 39-hour week with unsocial hours).

There are no translators employed in prisons on a permanent basis. The Ministry of Justice Language Service Contract provides face-to-face and telephone interpretation services for prisons, on a case-by-case basis, on request.

We are delivering 40 Rapid Deployment Cells at HMP Huntercombe. Units were deployed at the site in September 2023 and essential works are ongoing to get the units ready for occupation. First prisoners are expected to occupy the units from early January 2024.

There is no current plan to deliver Rapid Deployment Cells at HMP Maidstone or HMP Morton Hall.

The Rapid Deployment Cells Project is a key element of the HMPPS Programme to create short-term prison places and this project has a clear strategic goal to deliver additional places at prisons across the country, whilst long-term capacity is built.

We will continue to explore where Rapid Deployment Cells could potentially be deployed at prisons across the estate.

The population, operational capacity and certified normal accommodation (CNA) level of every prison is published monthly: Prison population figures: 2023 - GOV.UK (www.gov.uk).

HMP Huntercombe, HMP Maidstone and HMP Morton Hall are the three foreign national offenders (FNO) only prisons within HMPPS. They hold only those of interest to the Home Office with between 3 and 36 months left to serve. They include embedded Home Office staff with better access to FNOs to facilitate effective deportations.

The table below provides the operational capacity and certified normal accommodation level at (a) HMP Huntercombe, (b) HMP Maidstone and (c) HMP Morton Hall on 16 October 2023.

The Operational Capacity of a prison is the total number of prisoners that an establishment can hold taking into account control, security and the proper operation of the planned regime. It is determined by the Prison Group Directors on the basis of operational judgement and experience.

We are committed to increasing the number of FNOs removed from our prisons, and all FNOs sentenced to custody are referred to us at the earliest opportunity to be considered for deportation.
