When Can NHS Staff Legally Restrain a Patient?

Restraint is only lawful as a last resort - after de-escalation, verbal intervention and other options have genuinely been tried and haven't worked, and only where there's a real risk of harm to the patient or others.

It has to be proportionate to the risk, used for the shortest time necessary, and properly recorded afterwards.

For mental health units specifically, the Mental Health Units (Use of Force) Act 2018 - often called Seni's Law - puts a legal duty on hospitals to have a use-of-force policy, train staff properly in it, and record and report every use of force. It exists precisely because restraint carries real risk of physical and psychological harm when it's used without proper training behind it.

Knowing the legal threshold is one thing; recognising in the moment whether you've actually reached it is another - that's the gap our Advanced Conflict Management: Clinical Holding course is built to close.
