The prison was given a full inspection in July 2026, the full report can be read on the HM Inspectorate of Prisons website, just follow the links below. In their latest report the inspectors said:
HMP & YOI Chelmsford is a category B local prison for adult men in Essex, run by HM Prison and Probation Service, holding 661 prisoners against an operational capacity of 660, with 64% on remand, 16% foreign nationals and 24% from a minority ethnic background. This was a reinspection following the 2024 visit, itself a reinspection after the Urgent Notification issued in August 2021. Inspectors rated safety reasonably good, an improvement from not sufficiently good in 2024, and preparation for release also improved to reasonably good from not sufficiently good, while respect and purposeful activity both remained not sufficiently good, unchanged.
Inspectors found the improvements made since the Urgent Notification had been sustained and built upon. Drug use had been reduced, with a random mandatory drug test positive rate of 16%, far lower than at most similar prisons, violence had fallen significantly, and leaders had worked with prisoners to design an imaginative range of incentives for good behaviour, including the chance of an enhanced family visit. Self-harm was down by 23%, relationships between staff and prisoners were generally good, and better retention meant a more experienced team. An impressive library sat at the heart of the jail, family contact was supported through an extensive and creative range of initiatives, and an innovative resettlement centre offered strong help with housing, drug treatment and employment ahead of release. Inspectors recorded eight examples of notable positive practice, and the Chief Inspector said Chelmsford was now safer, more supportive of prisoners and better led than most of the reception prisons the inspectorate visits.
Inspectors nonetheless raised 15 concerns, five of them priorities. Self-harm remained higher than at similar prisons, and health care, a concern at the last inspection too, continued to be hampered by longstanding governance issues, with prisoners missing hospital appointments for lack of escort staff and mental health and drug treatment services under-resourced. Many prisoners still did not get enough time out of their cells, with Fridays particularly poor as staff training meant officers often failed to turn up, and the jail was not doing enough for disabled prisoners, younger men and those on the vulnerable prisoner wing. Monitoring of phone calls, especially for prisoners with restrictions on contact with children, was still not good enough despite being raised at the last two inspections.
