What Happens When Young People Become Adults?
Adulthood does not arrive all at once, even though the paperwork can make it feel that way. Services change, new teams get involved and some familiar support comes to an end — but support does not simply stop at 18. Knowing roughly what changes, and when, takes a lot of the uncertainty out of it.
- Transition planning is about preparing for adulthood: where someone will live, learn, work, and how they will stay connected and well.
- For young people with an EHCP, preparing for adulthood should be part of annual reviews from Year 9 (around age 13 to 14).
- Children's social care support may end or change, with adult social care taking over where the person is eligible under the Care Act 2014.
- Education can continue after 18 — an EHCP can remain in place up to age 25 while it is still needed for education or training.
- Health support often moves from children's services to adult services, sometimes with a different team, referral route or waiting time.
- Adults are assumed to be able to make their own decisions under the Mental Capacity Act, with support to do so where needed.
- Some benefits change at 16 and again at adulthood, for example moving from DLA to PIP.
- Planning early helps: it gives time to visit options, ask questions, gather evidence and challenge decisions if needed — instead of deciding under pressure.
Planning ahead is easier with someone alongside you. Advocacy and community services can help you understand options and speak up in meetings.
