The Mental Health Act 2025 & its impact on the social care sector
The Mental Health Act 2025 represents the most significant reform to mental health legislation in decades. With Royal Assent granted on 18 December 2025 and phased implementation beginning on 18 February 2026, the Act introduces a modern framework for how people with mental health needs can be supported, safeguarded and empowered.
When fully implemented, these reforms will not only reshape the experience of individuals subject to the Act but will also have important operational implications for social care providers working within increasingly complex community environments.
This article provides an overview of the key changes introduced by the Act and highlights the areas likely to have the greatest impact on social care providers. Join us for our webinar with Care England on 21 April and learn what you can do to prepare for its implementation.
The broad scheme of the Act
What will the Act do?
The Mental Health Act 2025 amends and updates the Mental Health Act 1983, aiming to modernise and align mental health law more closely with the values underpinning contemporary society, and mental capacity and human rights legislation.
When fully implemented, the Act is expected to deliver several core shifts:
- Empowerment and representation – promoting advance decision making about an individual’s own care, choice over their ‘nominated person’ (no longer a ‘nearest relative’) with expansion of the range of decisions on which nominated persons need to be consulted, and widening the role of Independent Mental Health Advocacy
- Improving access to the Tribunal & its procedures – giving detained patients more frequent access to Tribunal, and increasing the Tribunal’s powers to (for example) approve certain care arrangements amounting to a DOL, and scrutinise care and treatment plans
- Moving treatment from hospital to the community – reserving hospital for the most serious cases, while bringing all other patients (particularly those with learning disabilities and autism) into the community for treatment
- Introducing an approach to decision making in mental health law based on four core principles of ‘choice and autonomy, ‘least restriction’, ‘therapeutic benefit’ and seeing ‘the person as an individual’. A revised Code of Practice is expected to clarify how these principles will operate in practice.
Consultation on the draft Code is anticipated to happen later this year, with a final version of the Code expected around 12 months after that.
Implementation
Though certain changes being made by the Act came into force in February 2026, those changes are unlikely to have a significant impact on the social care sector.
At the time of this article, it appears likely that the remainder of the Act will be implemented over the next 10 years. Giving time for the new Code of Practice, we consider the next tranche of significant changes could come into force in around 18–24 months from the consultation on the Code of Practice starting.
This is, however, only our best guess. In this article, we look to consider what the impact on social care providers will be and identify key ‘points to prepare for’ for the sector.
Impact on social care providers
While the Act will affect a wide range of stakeholders, its implications for social care providers are likely to be most visible at an operational level.
Three themes stand out:
- Increasing complexity of need
With fewer individuals expected to be detained, it is likely social care providers will need to prepare to support more individuals with highly complex mental health needs within community settings. This reinforces the importance of ensuring staff competence and training to meet the needs of an increasingly complex patient group.
Noting that over the longer term, the Act is particularly looking to ensure that no individuals with learning disabilities or autism are detained by that reason alone, it would seem even more timely for providers to prioritise their mandatory Oliver McGowan training.
Point to prepare for: What are the services your organisation offers, and how might caring for individuals with a greater complexity of mental health need affect your day-to-day operations? Consider training, staffing needs, staffing qualifications, and resourcing requirements
- Care and treatment plans on a statutory footing
For the first time, the Act places on a statutory basis care and treatment plans for patients within its scope. The Act provides that this will apply to patients in the community who are ‘liable to be detained’ other than in certain emergency situations, where the individual is subject to guardianship under the Act, or is subject to a CTO. The purpose of this care plan is, at a minimum, to set out a plan for how a patient’s needs ‘arising from or related to mental disorder’ are to be met. Should those patients be discharged, and owed a s 117 ‘aftercare duty’ it is likely such care plans will be a strong starting point for identifying what needs they have and how they should be met
Where service users are therefore subject to a CTO or owed a duty under s 117, on inspection it is likely that the CQC will look – at a minimum – to see (1) whether a service user’s care and treatment plans are held locally, (2) evidence of the strength of communication between providers and community mental health teams, and (3) how well those care plans have been taken into account, and align with the full range of support the individual is getting. Without evidence of these care plans being held and acted upon, providers are at increasing risk of falling down on the ‘Person Centred’ pillar of assessment.
Point to prepare for: Do you know which service users are under a CTO or entitled to s 117, and what services they have been assessed as needing to meet their needs ‘arising from or related to mental disorder’? Do you discuss this with service users in care plan reviews? Is this information written down, and held in your records? Do you know who is the key point of contact for the individual’s care plan? If not, can you encourage staff to think about these possibilities when bringing a person’s care plans together?
- Greater emphasis on advance decisions
The importance of advance planning – which is already a CQC priority under ‘planning for the future’ Quality Statement – is elevated further by the Act. In preparation for a CQC inspection, providers should look to ensure that any service user who may be liable to detention under the Act has had the opportunity to discuss, and have recorded, a clear ‘advance decision’ capturing their wishes and preferences for treatment under the Act.
This would sit alongside existing planning requirements such as end‑of‑life planning, and absent evidence of it being explored, providers are again at risk of falling down on the ‘Person Centred’ pillar of assessment.
Point to prepare for: Do you have a holistic view of your service user’s mental health, and mental capacity? Do you discuss planning for the future with individuals routinely? Does, or could, this include a discussion about mental health care treatment? What training could staff benefit from to support them having these discussions?
Conclusion
The Mental Health Act 2025 marks a fundamental shift in the legal and operational landscape of mental health care in the UK. Its emphasis on autonomy, community support, and interdisciplinary coordination will require social care providers to adapt their practices, enhance staff training and ensure robust collaboration with mental health services.
While the impact on the social care sector is not likely to be immediate, it is likely to be felt profoundly by those providers working with patients under the Act. We have identified some points for thought above, and will be providing periodic updates as we get to know more about the Act, the Code, and how the new modern approach will work.
To support providers through these changes, we invite you to join our webinar on 21 April, where we will explore the Act in more depth, share updates, and discuss real, practical steps providers can take to prepare for implementation.
