HMP Onley, a Category C prison, experienced a challenging year with significant increases in violence and self-harm incidents.

Significant progress was made in resettlement with new partnerships (Greene King, rail track) leading to employment opportunities.

Board Commentary
Staffing
Significant staffing challenges persist across the prison, including in healthcare, substance misuse, and offender management, with several vacancies and reliance on agency staff. Delays in vetting new appointees continue to impact recruitment. While key worker sessions have improved, some staff lack de-escalation skills, and there's limited awareness of the prison drugs strategy.
Healthcare
Healthcare provided by Practice Plus Group has improved in medicine management according to HIMP/CQC. However, significant concerns remain regarding long waiting times for GP appointments, which are deemed unacceptable, and lengthy dental waiting lists. Staffing shortages persist across the healthcare team, notably with no psychologist or assistant psychologist in post, and vacancies in nursing and paramedic roles.
Regime & Daily Life
The regime at HMP Onley is hampered by a lack of purposeful activity and engagement, resulting in many prisoners spending considerable time locked in their cells. Despite a new incentives-driven activities policy, approximately 300 prisoners lack access to work or education. Prisoner comments indicate only two hours out of cell daily and a desire for more socialisation and sport.

Recommendations (12)
Ministry of Justice: 3 HMPPS: 4 Governor / Director: 5 5 repeated
Recommendation 1 Repeated Prev. unaddressed
The Minister should address the persistent problem of missing, mislaid, and delayed prisoner property, particularly on transfer between prisons, which continues despite previous reports.
Ministry of Justice Resettlement
Response
Referred to the Prisoner Property Policy Framework Sept 2022. The Framework does place an emphasis on ensuring compliance with volumetric control limits; anything within these limits will be transferred with the prisoner. 4-week delays are within the Framework. Feedback commonly identifies the need to introduce digital systems to replace paper-based processes for recording prisoners’ items. Digital proposals will be longer term due to the need to prioritise.
Recommendation 2 Repeated Prev. unaddressed
The windows and window frames across the establishment are in a poor condition and an entry point for drone packages and rats. The Minister should arrange for these windows to be replaced, as they are no longer fit for purpose, are an easy target for drone drops and endanger the ongoing security and stability of the establishment.
Ministry of Justice Estate
Response
A programme of works to replace windows site-wide and install anti-barricade doors can now be developed and will be considered for funding once current costs are understood. The Governor has agreed to fund the installation of some new windows and window grills from the prisons budget which have been highlighted as a drone risk. Amey have been asked to cost this.
Recommendation 3
Delays in the vetting process are impacting on non-operational appointees taking up employment. The Minister should address these delays.
Ministry of Justice Staffing
Recommendation 4 Repeated Prev. unaddressed
The Prison Service should provide additional support to reduce drone activity at HMP Onley.
HMPPS Safety
Response
HMPPS continues to work hard to deter, detect and disrupt the illegal use of drones targeting our prisons. The Risk and Capabilities Unit have provided support and guidance to HMP Onley through the completion of a drone vulnerability assessment to understand the local threats and identify appropriate mitigations. A 400-metre drone Restricted Fly Zone has been introduced around all closed prisons. HMP Onley have implemented a local process to take immediate action following the sighting of a drone.
Recommendation 5
The increase in prisoners with severe mental health issues puts considerable strain on the staff. The Prison Service should provide additional support for such prisoners or find alternative, more suitable accommodation for them.
HMPPS Mental_health
Recommendation 6
The state of the floors, showers and cells on some wings and areas of the establishment is poor. The Prison Service should ensure that prisoners are living in a dignified environment.
HMPPS Estate
Recommendation 7
The Board’s view is that one washing machine for wings housing 60-100 prisoners is inadequate. The Board is also of the view that the choice of domestic washing machines over commercial washing machines is adding to the problem of frequent washing machine breakdowns. The Prison Service should address the inadequacy of laundry facilities.
