Section 5 MHA: The Holding Powers Explained for Patients and Families
Section 5 of the Mental Health Act 1983 contains two distinct short-term holding powers, Section 5(2) and Section 5(4), that allow informal (voluntary) patients in hospital to be temporarily prevented from leaving while a formal assessment for detention is arranged. This guide explains clearly how these powers work, who can apply them, how long they last, and what rights a person retains.
What Is Section 5 MHA?
Section 5 provides holding powers for patients who are already admitted to hospital, but as informal (voluntary) patients, not under a formal section. An informal patient has entered hospital voluntarily and would normally have the right to leave at any time.
Section 5 powers are used when a clinical professional has urgent concern that a voluntary patient who wishes to leave needs a formal mental health assessment before discharge would be safe. The powers buy time for that assessment to take place.
Section 5 does not authorise treatment without consent, it is solely a power to prevent departure while further assessment is arranged.
Section 5(2): The Doctor’s Holding Power
Who can apply it: Section 5(2) can be applied by the patient’s Responsible Clinician (RC), usually the consultant psychiatrist, or by their nominated deputy, who must be a registered medical practitioner.
How it works: The doctor furnishes a report to the hospital managers stating that the patient needs to be detained in the interests of their own health or safety, or for the protection of others, and that formal assessment for detention is required.
Duration: Section 5(2) lasts for a maximum of 72 hours from the time the report is furnished. This provides a 72-hour window for a full Mental Health Act assessment to take place.
What happens during the 72 hours: An AMHP and two doctors should assess the patient to determine whether a Section 2 or Section 3 is warranted. If the assessment concludes that formal detention is not required, the Section 5(2) lapses and the patient resumes informal status.
Limitations: Section 5(2) can only be applied by a doctor who is responsible for the patient’s care, or their nominated deputy. It cannot be used for outpatients or patients in accident and emergency departments.
Section 5(4): The Nurse’s Holding Power
Who can apply it: Section 5(4) can be applied by a registered nurse, specifically one whose ordinary nursing speciality is mental illness or learning disability. This must be a nurse with the appropriate professional registration and specialist practice.
How it works: The nurse forms the view that the patient is suffering from a mental disorder to such a degree that it is necessary for their health or safety (or for the protection of others) that they be prevented from leaving, and that it is not practicable to secure the immediate attendance of a doctor.
Duration: Section 5(4) lasts for a maximum of 6 hours from the time it is invoked, or until a doctor arrives and either invokes Section 5(2) or decides that detention is not required.
The purpose of Section 5(4): It fills the gap that would otherwise exist out of hours or in emergencies when a doctor is not immediately available. It provides a short but legally authorised window for the nurse to prevent a patient who poses immediate risk from leaving before a doctor can attend.
What Are the Patient’s Rights Under Section 5?
The right to information: The patient must be informed that they are being held under a holding power and should be told why.
The right to advocacy: Patients held under Section 5 are entitled to access an Independent Mental Health Advocate (IMHA), though the very short duration of Section 5(4) makes this difficult to access in practice within that time frame.
The right not to be treated without consent: Neither Section 5(2) nor Section 5(4) gives authority to treat a patient without their consent. They are purely holding powers.
The right to challenge: As holding powers are very short in duration, formal appeal mechanisms (such as the Mental Health Tribunal) are not practically available within the timeframe of Section 5. However, if the holding power results in a formal Section 2 or Section 3, full appeal rights become available.
How Section 5 Fits into the Broader MHA Framework
Section 5 is a gateway, a short-term tool that enables a safe transition from informal status to formal assessment, where clinical concern is urgent. The hierarchy runs broadly:
| Section | Purpose | Duration | Applied by |
| 5(4) | Nurse’s emergency hold | 6 hours | Specialist nurse |
| 5(2) | Doctor’s hold | 72 hours | RC or deputy |
| 4 | Emergency assessment | 72 hours | One doctor + AMHP |
| 2 | Assessment | 28 days | Two doctors + AMHP |
| 3 | Treatment | 6 months (renewable) | Two doctors + AMHP |
Supporting Wellbeing After a Holding Power Experience
Being held in hospital, even under a short holding power, can be a frightening and disorienting experience. The physiological impact of the associated anxiety and stress is real and often persists after the holding itself has resolved.
At Herba Naturalle, the Nervous System Reset Bundle is designed to support the physiological recovery of the nervous system after periods of acute stress, anxiety, and psychiatric crisis. The Gotu Kola Complex within the bundle specifically targets the surface nervous system, the physiological layer that holds the residual anxiety and vigilance after a frightening experience.
