England and Wales. Least restrictive practice is a legal and ethical obligation under the MCA 2005, MHA 1983 Code of Practice, and ECHR Articles 5 and 8.
Core Principles
Restriction Ladder
Always start at the lowest level of restriction. Move up only when lower levels have been tried and are insufficient to manage risk safely.
No restriction
Person makes their own informed decision with information and support.
Verbal guidance
Gentle verbal redirection or guidance without physical intervention.
Environmental modification
Adjusting the environment to reduce risk (e.g., removing hazards, locked doors).
Supervision
Increased observation and monitoring without physical restriction.
De-escalation
Therapeutic verbal and non-verbal techniques to reduce distress and agitation.
Medication (voluntary)
PRN medication offered and accepted voluntarily by the patient.
Physical intervention
Physical holding or restraint — only when all other options have been exhausted and there is immediate risk of harm.
Seclusion
Placing a patient alone in a locked room. Strict legal and policy requirements apply under the MHA Code of Practice.
Rapid tranquilisation
Emergency medication given without consent. Requires clinical justification, post-administration monitoring, and documentation.
