The Mental Health Act 2025 – a missed opportunity? What changes does it make and when?
The Mental Health Act 2025 (the 2025 Act) completed its Parliamentary passage on December 18, 2025. Does this mean that we can wave goodbye to the Mental Health Act 1983 (the 1983 Act)? Unfortunately, the answer is no. The 57 sections and the three schedules to the 2025 Act are almost exclusively concerned with making amendments to the 1983 Act and many of the provisions contained in the 1983 Act remain untouched. There is no evidence to suggest that the UK Government considered the option of preparing a Consolidating Bill. As set out in the preface to the 27th edition of the Mental Health Act Manual:
If the Mental Health Act is to be modernised, is it appropriate to base the modernisation on a legislative structure that was established over 60 years ago by the Mental Health Act 1959? The process of bolting on multiple miscellaneous amendments to that structure over the years has resulted in an Act which is overly complex, confusing, and expensive to operate…
This unfortunate situation is exacerbated by the UK Government’s estimate that the provisions in the 2025 Act will be brought into force in a piecemeal fashion over a ten year period. Some of the 2005 Act’s provisions, noted below, will come in force on 18 February even though a updated Code of Practice has not been published in England or in Wales, and is unlikely to be published soon.
Although some of the 2025 Act’s provisions have merit, many of the proposals contained in the ‘Independent Review of the Mental Health Act’ (the Wessley Review) that eventually found their way into the 2025 Act were high on rhetoric, but low on evidence. Indeed, the process that was followed can be categorised as a prime example of the “Stakeholder State” in that respected “stakeholders” submitted proposals to the Wessley Review that chimed with current thinking and were accepted in the absence of any evidence that they would improve matters.
The provisions of the 2025 Act that will come into force on 18 February, 2026, include:
Conditional discharge for restricted patients
It will be possible for the Secretary of State for Health and Social Care (the SoS) to impose conditions amounting to a deprivation of liberty (DoL) when discharging restricted patients. Such conditions can be imposed if the SoS is satisfied that those conditions are necessary for the protection of the public from serious harm. This new power responds to the decision of the Supreme Court in MM v Secretary of State for Justice [2018] UKSC 60, which confirmed that a patient with capacity cannot be discharged in this manner under the 1983 Act.
For the Mental Health Tribunal in England and Mental Health Review Tribunal for Wales (the Tribunal) to effect such a discharge it must be satisfied that:
- (1) conditions amounting to a DoL would be necessary for the protection of another person from serious harm while discharged; and
- (2) that for the patient to be discharged subject to those conditions it would be no less beneficial for their mental health than for them to be recalled to hospital.
Tribunal applications and references
Because of the new provisions relating to the conditional discharge of restricted patients, timetables for applications and references to the Tribunal have been updated in the amendments made to subsections (1) and (2) and the insertion of subsection (2A) into section 75 of the 1983 Act which now reads as follows:
“Applications and references concerning conditionally discharged restricted patients.
- (1) Where a restricted patient has been conditionally discharged under section 42(2), 73 or 74 above (“conditionally discharged”) and is subsequently recalled to hospital:
- (a) the Secretary of State shall, within one month of the day on which the patient returns or is returned to hospital, refer his case to the appropriate tribunal; and
- (b) section 70 above shall apply to the patient as if the relevant hospital order, hospital direction or transfer direction had been made on that day.
- (2) Where a restricted patient has been conditionally discharged as aforesaid but, is not subject to conditions amounting to a deprivation of liberty and has not been recalled to hospital he may apply to the appropriate tribunal:
- (a) in the period between the expiration of 12 months and the expiration of two years beginning – beginning with the date on which he was conditionally discharged;
- (i) in the case of a patient who has previously been subject to conditions amounting to a deprivation of liberty, with the date on which the patient most recently ceased to be subject to such conditions; and
- (ii) in any other case, with the date on which the patient was conditionally discharged; and
- (b) in any subsequent period of two years.
- (2A) Where a restricted patient has been conditionally discharged, is subject to conditions amounting to a deprivation of liberty and has not been recalled to hospital, the patient may apply to the appropriate tribunal:
- (a) in the period between the expiration of six months and the expiration of 12 months beginning with the date on which the patient most recently became subject to conditions amounting to a deprivation of liberty (whether or not that was the date on which the patient was conditionally discharged); and
- (b) in any subsequent period of two years.”
Extending the remit of s48 in relation to the removal to hospital of other patients
The power of the Secretary of State to remove unsentenced prisoners to hospital for medical treatment will be extended to include persons detained under:
- (i) the Immigration Act 1971;
- (ii) section 62 of the Nationality, Immigration and Asylum Act 2002 (detention by Secretary of State);
- (iii) section 36 of the UK Borders Act 2007 (detention of offenders for deportation); or
- (iv) regulation 32 of the Immigration (European Economic Area) Regulations 2016 (S.I. 2016/1052) (which are saved by the Citizens’ Rights (Restrictions of Rights of Entry and Residence) (EU Exit) Regulations 2020 (S.I. 2020/1210)).
The rest!
Rather than summarising the provisions of the 2025 Act that will (or will not) be brought into effect during the next ten years, we will be publishing separate bulletins at the relevant times.
