High levels of illicit substances and drone activity contributed to violence and self-harm, while a large number of inexperienced officers struggled with de-escalation. Despite some improvements, the estate suffers from poor cell conditions and broken essential equipment, impacting prisoner well-being and purposeful activity.

Positive findings
AI-generated summaryThe Board observed professionalism and care in reception and induction, with improvements in ACCT documentation and key work session completion. Positive developments include the introduction of safety officers, peer mentoring, and a well-received 'Feel Good Friday' regime initiative. Healthcare made efforts to improve communication, and the OMU effectively managed transfers. Education tutors were commended, and the library was popular, with strong engagement from the Employment Advisory Board and the Greene King Academy for resettlement.
Key concerns
The high availability of illicit substances has driven debt, self-harm, bullying and violence despite the remedial work of prison staff
Despite interceptions, there continued to be a significant level of drone activity.
There continued to be high numbers of inexperienced prison officers on the wings who lacked the skills to de-escalate challenging situations.
Frequently prisoners felt frustrated that their complaint and/or the complaint process had failed to address the issue or issues they had raised
The poor condition of most cell windows enabled access for vermin and illicit items via drones
Cell doors on some wings enabled prisoners to barricade
Despite some redecoration, the cells and shower facilities on the older wings remain in a poor condition and require attention
There were ongoing issues with repairs and/or replacements of kitchen machinery, wing washing machines and tumble dryers
Food choice, quality and quantity was considered poor by many prisoners.
There were long wait times for non-emergency dental appointments
Despite the mental health team being fully staffed by the end of the reporting year, they had no capacity to provide additional mental health interventions.
There were ongoing challenges to improve prisoner engagement in education and employment
Approximately 200 prisoners were on the waitlist for the Building Choices programme at the end of the reporting year due to staff shortages.
Urgent attention needs to be given to the vetting of prison officers and staff recruited by partner agencies because the length of time it is taking is having a negative impact on the daily operation of the prison.
The length of time it is taking to replace laundry and catering machinery parts and/or broken equipment is having a negative impact on the daily lives of prisoners.
The recruitment and retention of prison officers remain an ongoing concern.
The dropping of illicit items via drones continued to threaten the safety of all at HMP Onley.
The site wide upgrade of the closed-circuit television (CCTV) system is not happening despite assuring the Board in the response to last year’s annual report that funding had been secured.
What further investment can be made to enable unused workshops to be brought back into operation so activity space capacity can be increased?
Emergency escorts on occasion were declined by the prison due to staffing issues.
Property not following the prisoner on transfer to HMP Onley from another establishment continues to cause frustration.
Recommendations
Urgent attention needs to be given to the vetting of prison officers and staff recruited by partner agencies because the length of time it is taking is having a negative impact on the daily operation of the prison. How does the Minister plan to address this?
Government response
Regarding the delays in recruitment due to security vetting, I understand the operational pressures this can cause. However, I must stress that vetting is a critical safeguard for our institutions. Current data indicates that most pre-employment checks are completed in a timely manner with most cases concluded within a matter of days once all required applicant information is provided. I appreciate that the local vetting process at HMP Onley does not permit for prioritisation, but I am reassured that the team monitors applications closely and engages regularly with vetting services to reduce avoidable delay.
Recommendation 2
The length of time it is taking to replace laundry and catering machinery parts and/or broken equipment is having a negative impact on the daily lives of prisoners. What does the Minister plan to do about the failure of these maintenance contracts?
Recommendation 3
When will a start date be given for the window and door replacement programme?
Government response
I can confirm that the major capital project commissioned to replace the windows and doors in A, B, C, D, E and G and H wings is progressing and will be considered for funding to begin delivery in the 2026/27 financial year. As referred to in my response to last year’s report, the provision of local funding has enabled progress to begin sooner on specific elements of this work. This includes the manufacturing and fitting of some new window grills on I Wing.
Recommendation 4
The recruitment and retention of prison officers remain an ongoing concern. If continued shortages impact on the scheduled opening of the new house blocks at the end of 2026 how will this be addressed?
Recommendation 5
What further investment can be provided to help tackle the constant drone incursions at HMP Onley?
Government response
Drone incursions remain a complex and evolving threat, which are increasingly linked to organised criminal activity. At HMP Onley, targeted upgrades are underway to address this risk. Funding has been secured for a site-wide upgrade of the Closed-Circuit Television (CCTV) system, which is expected to be complete by March 2026. In tandem, a project to replace all the windows across the older wings is progressing and will be considered for funding to allow delivery to begin in the 2026/27 financial year.
Recommendation 6
Can the Prison Service explain why the site wide upgrade of the closed-circuit television (CCTV) system is not happening despite assuring the Board in the response to last year’s annual report that funding had been secured?
Recommendation 7
What further investment can be made to enable unused workshops to be brought back into operation so activity space capacity can be increased?
Recommendation 8
Can the Governor provide assurance that work to improve the standard of the outside exercise yards will commence and that improved standards will be maintained?
Government response
Work parties were engaged to improve the condition; some maintenance was evidenced.
