Update mental vulnerability and mental capacity DSO guidance

Recommendation

The Home Office must review and update Detention Services Order 04/2020: Mental Vulnerability and Immigration Detention: Non-Clinical Guidance to set out comprehensive guidance for detention and healthcare staff where there are concerns that a detained person is suffering mental ill health or lacks mental capacity. This must include an appropriate system for: the routine handover or sharing of relevant information between detention custody staff and healthcare staff (for example, in Security Information Reports and Anti-Bullying Support Plans); the identification and follow-up of missed medical appointments; the assessment of mental capacity where indicated; and mental health assessment where indicated. The Home Office must ensure that training about the updated guidance takes place on a regular (at least annual) basis for detention and healthcare staff, as well as those responsible for managing them. The training must be subject to an assessment.

Published Evidence Summary
The following publicly available evidence relates to this recommendation:
The Home Office stated it was considering policy on detained people with mental ill health as part of wider work on vulnerable adults and scoping requirements with NHS England (Government Response, March 2024). While the government reported in January 2025 that this was on track for closure by summer 2025 (Angela Eagle, Written PQ 23170, 15 January 2025), a High Court ruling in December 2025 found a systemic disconnect between Adults at Risk policy, ACDT systems, and Rule 35 processes at Brook House (AH and IS v SSHD [2025] EWHC 3269 (Admin)). HM Inspectorate of Prisons also reported "Insufficient Progress" in August 2025, noting limited engagement with charities and issues with adults at risk.
