Waiting times for children's ADHD assessment differ enormously between areas — the same referral can be seen in months in one place and years in another. Nothing about the wait is within your control, but several things around it are.
Find out where you actually stand
- 1Ask your GP practice to confirm the referral was sent, and to which service.
- 2Contact that service directly and ask for the current average wait and your position.
- 3Ask whether the referral is complete — missing school information is a common cause of delay.
- 4Ask about patient choice: whether you can be referred to another provider with a shorter wait.
- 5Diarise a call every three months, and keep a note of names and dates.

Support you do not have to wait for
A diagnosis is not a prerequisite for help at school. Under the SEND framework in England, schools must use their best endeavours to support any child with additional needs, based on need rather than on a label.
- Request a meeting with the SENCO and ask for a written support plan.
- Ask for classroom adjustments now: seating, chunked instructions, movement breaks, extra processing time.
- Look for local parent support and ADHD parenting programmes, which are often available pre-diagnosis.
- Prioritise sleep and routine — both change day-to-day functioning quickly.
- Keep a dated diary of incidents; it becomes evidence for the assessment.
Frequently asked questions
- How long are ADHD waiting lists for children in the UK?
- They vary widely by area, from months to several years. Your local service is the only reliable source for your own wait.
- Can I choose a different NHS provider?
- In many cases yes — ask your GP about patient choice and whether an alternative provider has a shorter wait.
- Can school support start before diagnosis?
- Yes. Support should be based on need, not on a diagnosis, and you can request it now.
