As the Mental Health Bill 2024–25 progresses through Parliament, it is set to bring some of the most substantial changes to mental health legislation in England and Wales in decades. The Bill has now completed the committee stage in the House of Commons, where several significant amendments were either upheld or reversed. For those working in adult social care, especially in statutory or commissioned services, these reforms carry important implications for practice, accountability, and patient rights.
Why Is the Mental Health Bill Being Introduced?
The current Mental Health Act has long been seen as outdated, overly reliant on restrictive powers, and insufficiently protective of individual rights. The new Bill aims to modernise mental health legislation by placing greater emphasis on patient autonomy, better oversight of compulsory powers, and improved integration with human rights frameworks. These changes also respond to longstanding concerns around racial disparities, inappropriate detentions, and the overuse of hospital settings.
Key Areas of Debate and Change
Powers of Detention: Police vs Professionals
One of the most contentious issues was whether to extend police powers under Sections 135 and 136 of the Mental Health Act to health and social care professionals, including Approved Mental Health Professionals (AMHPs). While the House of Lords passed this amendment, the government ultimately removed it in the Commons. Concerns focused on safeguarding therapeutic relationships and avoiding unnecessary criminalisation of mental health crises. The final position maintains that only police should hold these powers.
Community Treatment Orders (CTOs)
The Bill was also set to limit CTOs to a maximum of 12 months and require a second psychiatrist’s agreement to renew them. These changes were intended to prevent indefinite restrictions on liberty. However, the Commons overturned the proposal, arguing that the current review system already includes sufficient checks and balances. The government emphasised that CTOs can only be extended if there is a serious risk to the patient or others, and a reasonable expectation of therapeutic benefit.
The Role of the Nominated Person
Replacing the “nearest relative” with a “nominated person” is another major reform. For individuals under 16 who cannot make decisions themselves, the Lords introduced a structured hierarchy to guide who could act in this role. The Commons removed this hierarchy, asserting that local authorities and AMHPs need discretion to appoint the most appropriate adult in each unique situation. The final wording prioritises parental responsibility but retains professional judgment.
Human Rights Protections in Private Settings
One of the most widely welcomed changes is the confirmation that private care providers commissioned by local authorities or the NHS under Section 117 must now be treated as public bodies for the Human Rights Act. This closes a longstanding legal gap and ensures that vulnerable individuals in non-NHS settings are afforded the same legal protections as those in public care.
Strengthening Advance Choice Documents
Advance Choice Documents (ACDs) allow people to outline their treatment preferences while they are well, offering a tool for self-advocacy during future crises. The Bill now places clear duties on health bodies to provide information about ACDs, ensure individuals receive help in completing them, and discuss these documents within a year of discharge from mental health detention. This change aims to give more weight to the patient voice and reduce unnecessary interventions.
Missed Opportunities and Ongoing Advocacy
Several important amendments were not adopted, including proposals to give AMHPs a role in Section 3 renewals and to place legal duties on local authorities to promote mental wellbeing. The government also resisted calls for mandatory debriefing sessions with Independent Mental Health Advocates post-discharge, citing concerns over system capacity.
The Bill also does not provide a clear timetable for implementing the long-delayed Liberty Protection Safeguards (LPS), which are intended to replace the current Deprivation of Liberty Safeguards (DoLS). Ministers now indicate they are reconsidering the value of LPS altogether, a move that continues to cause uncertainty within the sector.
What Happens Next?
The Bill will soon return to the House of Commons for its report stage and third reading, followed by a final review in the House of Lords. Once both Houses agree on the final wording, the Bill will receive Royal Assent and become law. Implementation will then begin with a new Code of Practice by 2026, followed by training and phased reforms from 2027. Full implementation may take up to a decade.
What It Means for Adult Social Care
For practitioners and commissioners, the Bill underscores the need for legally sound, person-centred decision-making. It reinforces the value of timely assessments, capacity-focused approaches, and clear care planning. It also highlights the ongoing role of AMHPs and the legal weight of the decisions they are asked to make.
