Recommendations

Recommendation 1

Addressee: Ministry of Justice

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?

Repeated Source text verified

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 3

Addressee: HMPPS

When will a start date be given for the window and door replacement programme?

Repeated Source text verified

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.

What further investment can be provided to help tackle the constant drone incursions at HMP Onley?

Repeated Source text verified

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.
