### Script


`[CUE 1]` *A timeline from Royal Assent in December 2025 to commencement over ten years, with a marker for today*

**EMMA**  [00:00]
George, the new Mental Health Act. I've seen a dozen posters, three training days and two rumours. Is it law yet?

**GEORGE**  [00:08]
It's law, but it isn't all in force. That distinction is the first thing to get clear. Royal Assent was 18 December 2025. That made it an Act. It didn't switch the provisions on.

**EMMA**  [00:22]
So when does it start?

**GEORGE**  [00:24]
In pieces. A small number of provisions are already in force. Most have to be commenced by regulations, and the plan is phases over potentially ten years. The statutory Code of Practice has to be drafted, consulted on and published first. Workforce training is planned for 2026 and 2027, and the first major phase is expected from 2027.


`[CUE 2]` *Four principles as four cards: choice and autonomy, least restriction, therapeutic benefit, the person as an individual*

**EMMA**  [00:47]
What do I do on the ward on Monday?

**GEORGE**  [00:50]
Keep working to the 1983 Act as it stands until your trust tells you a provision is in force. Don't change practice because of what the 2025 Act will provide. That's the single most useful sentence in this course.

**EMMA**  [01:06]
Right. What's it actually trying to do?

**GEORGE**  [01:09]
Four principles, taken from the independent review in 2018. Choice and autonomy. Least restriction. Therapeutic benefit. And the person as an individual. The Code of Practice has to reflect them.


`[CUE 3]` *A balance showing nature, degree and likelihood of harm on one side and a reasonable prospect of therapeutic benefit on the other*

**EMMA**  [01:21]
Principles are easy to write. Do they change anything?

**GEORGE**  [01:24]
They explain the rest. Choice is why people can plan ahead. Least restriction is why a restriction needs justifying. Therapeutic benefit is why detention has to be for treatment that has a real prospect of helping. And the individual is why culture, history and preferences matter.

**EMMA**  [01:43]
The part everyone asks about is who can be detained.

**GEORGE**  [01:47]
Under sections 2 and 3, there has to be a risk of serious harm, to their own health or safety or someone else's. And the decision maker has to consider the nature, the degree and the likelihood of it. So possible harm isn't enough any more.


`[CUE 4]` *A vague observation note beside a specific timed note with behaviour, risk and response*

**EMMA**  [02:05]
And section 3 specifically?

**GEORGE**  [02:07]
There has to be real therapeutic benefit. The treatment available must have a reasonable prospect of alleviating the disorder, or stopping it getting worse, or easing symptoms. Treatment that can't offer that isn't a basis for compulsion.

**EMMA**  [02:22]
I'm a nurse, though. I don't detain anyone.

**GEORGE**  [02:25]
No, that's for approved mental health professionals and doctors. But what you observe and write is what those decisions and the later reviews are built from. If the test asks about nature, degree and likelihood of harm, a vague note is no use to anybody.


`[CUE 5]` *A person with a learning disability or autism choosing community support before a crisis, with the new register and reviews in the background*

**EMMA**  [02:43]
What does a good note look like?

**GEORGE**  [02:46]
Specific behaviour, specific risk, specific response to treatment, in your own words and timed. Not agitated and unsettled all day. What they did, what you saw, what you did about it, what happened.

**EMMA**  [02:59]
What about learning disability and autism? I've heard that's big.

**GEORGE**  [03:03]
It is. Once those provisions commence, a person can't be detained for treatment under section 3, or put on a community treatment order, just because they have a learning disability or are autistic. They'd also need a psychiatric disorder that meets the criteria.

**EMMA**  [03:20]
So where do they go?

**GEORGE**  [03:22]
That's the point of the other half. Statutory Care and Treatment Reviews for detained children and young people. And integrated care boards have to keep a register of people at risk of admission, so support can be arranged in the community before a crisis.

**EMMA**  [03:39]
Anything I can do now?

**GEORGE**  [03:41]
Start asking, for anyone with a learning disability or autism, what support in the community would make admission unnecessary. And read your trust's commencement plan when it arrives, rather than a poster.

## What changes on the ward: voice, plans, timings and places of safety

**Runtime** about 4 minutes. **Words** 562. **Starts at** 03:54 in the full course recording.

### Learning outcomes to state on camera

- Explain the nominated person and how it differs from the nearest relative
- Explain opt-out independent mental health advocacy
- Describe statutory care and treatment plans and advance choice documents
- State the new detention periods and tribunal timings
- Explain the changes to community treatment orders, police cells and prisons
- List what to do now to prepare

### Script


`[CUE 1]` *A list of relatives with a line through it, and a person choosing their own nominated person*

**EMMA**  [03:54]
George, last time was the headline. Now give me the stuff I'll actually meet on shift. Start with the nominated person.

**GEORGE**  [04:03]
It replaces the nearest relative. Under the old rules the nearest relative came from a list in the Act, so the right to be consulted could land on an estranged parent or someone the patient had cut off.

**EMMA**  [04:18]
I've seen that go badly.

**GEORGE**  [04:20]
Everyone has. Now, if the person has capacity, they choose, and the choice carries on even if they later lose capacity. If they haven't chosen and can't, an approved mental health professional can appoint one. And the nominated person gets new consultation rights and can object to a community treatment order.


`[CUE 2]` *A patient with an advocate reaching out first, then a care and treatment plan and an advance choice document*

**EMMA**  [04:40]
What do I do about it before it's in force?

**GEORGE**  [04:44]
Ask early, while someone's well enough to answer. Who would you want us to speak to? Record the answer, and where it came from.

**EMMA**  [04:54]
What about advocacy?

**GEORGE**  [04:55]
Independent mental health advocacy extends to informal patients, on an opt-out basis. The service has to contact qualifying patients to offer support instead of waiting to be asked. Your job is making sure patients know the advocate exists and can reach them.


`[CUE 3]` *A table of the old and new detention periods and tribunal timings side by side*

**EMMA**  [05:12]
And care plans?

**GEORGE**  [05:13]
They become statutory. For people detained, on a community treatment order or under guardianship, the responsible clinician must prepare a plan and review it regularly. It's where the four principles stop being words.

**EMMA**  [05:26]
I've heard about advance decisions too.

**GEORGE**  [05:29]
Advance choice documents. Healthcare bodies must help people record their wishes and feelings and decisions about future care. Professionals must have regard to them, but they aren't absolutely binding. They're the clearest way someone can still be heard when they're unwell.


`[CUE 4]` *A community treatment order with each condition labelled, and a police cell crossed off a list of places of safety*

**EMMA**  [05:45]
Detention periods. I never remember these.

**GEORGE**  [05:48]
Nobody does, so here's the shape. First section 3 detention goes from six months to three. Renewable for three more. Then six months at a time instead of twelve. More renewals means more reviews, and more occasions where you need to show detention is still justified.

**EMMA**  [06:06]
And tribunals?

**GEORGE**  [06:07]
Section 2 patients can apply within 21 days instead of 14. Section 3 within three months instead of six. And there's automatic referral three months after initial detention, then every twelve months.


`[CUE 5]` *A checklist of preparation steps with a banner reading follow your trust's guidance*

**EMMA**  [06:20]
Community treatment orders?

**GEORGE**  [06:21]
They'll need the same serious harm criteria and appropriate treatment as detention, plus written agreement from the community clinician. And the tribunal can recommend reconsidering specific conditions, so every condition has to be one you can explain.

**EMMA**  [06:36]
Section 136. The police cells.

**GEORGE**  [06:38]
Police cells come out of the definition of a place of safety under sections 135 and 136. Prisons can no longer be a place of safety for people in contact with criminal justice. Local arrangements for people in crisis will have to change, and the government has agreed to consult on emergency police powers.

**EMMA**  [06:59]
So what do I do now? Concretely.

**GEORGE**  [07:02]
Don't change practice early. Do prepare. Find your trust's commencement plan. Check your recording habits. Ask people early who they'd want consulted and about their advance wishes. Make sure advocates are reachable. And read the Act's Explanatory Notes, which are free and clear. Including instead of this course, if there's a conflict.

**EMMA**  [07:23]
Including instead of this course?

**GEORGE**  [07:25]
Always. If anything I've said differs from your trust's guidance, or the statutory Code once it's published, follow them and tell us so we can fix it. A summary is a way in, not the authority.
