How long is the NHS waiting list for adult ADHD assessment in the UK?

Waits vary widely by region; 2–5 years or more is common in 2026, and some trusts have temporarily closed their waiting lists. Right to Choose is usually substantially faster.

What is Right to Choose for ADHD?

In England, you have a legal right to choose any NHS-contracted provider for outpatient mental-health assessment, including several NHS-contracted private providers. You stay within the NHS but typically wait months rather than years.

How much does a private ADHD assessment cost in the UK?

Typically £500–£1,500 for a one-off psychiatric assessment, plus ongoing costs for follow-up and medication if needed. A Shared Care Agreement can later shift long-term prescribing back to your NHS GP.

Can a GP diagnose ADHD?

No. In the UK, an ADHD diagnosis must be made by a psychiatrist (or, in some services, a specialist nurse) after a structured clinical assessment. GPs refer for assessment.

Is adult ADHD covered by the NHS?

Yes. Adult ADHD assessment, diagnosis, and treatment are covered by the NHS — either through your local service or via Right to Choose at an NHS-contracted provider.

How to Get an ADHD Diagnosis as an Adult in the UK

In the UK, adult ADHD is diagnosed by a psychiatrist after a structured clinical assessment. You have three routes: NHS (free, often long waits), Right to Choose (NHS-funded, faster), or private (typically £500–£1,500). All three end with the same legally recognised diagnosis. Here is exactly what each one involves, and how to navigate them.

Do I have ADHD as an adult? (the common signs)

Common adult ADHD signs include: lifelong difficulty with focus or follow-through; impulsivity; restlessness; struggles with time and planning; emotional sensitivity (often rejection-sensitive); chronic forgetfulness; cycles of intense interest followed by abandonment. Most adults who reach assessment recognise the pattern stretching back to childhood. Self-screening tools (the ASRS-v1.1, free online) are a reasonable starting point — they suggest but don't diagnose.

Step 1: Talk to your GP

Book a routine appointment. Tell them you'd like to be referred for an ADHD assessment. Helpful preparation: a brief written list of symptoms across childhood and adulthood, examples, and (if possible) collateral from a parent or partner. GPs cannot diagnose ADHD themselves — they refer.

Route A — NHS (free, long wait)

Your GP refers you to your local NHS adult ADHD service. Waiting lists vary widely by region; 2–5+ years is common in 2026, and some trusts have temporarily closed their lists. Free at point of care, with the same eventual outcome.

Route B — Right to Choose (NHS-funded, much faster)

In England, you have a legal right to choose any NHS-contracted provider for outpatient mental-health assessment — including several private providers that hold NHS contracts (Psychiatry UK, ADHD 360, ProblemShared and others). You're still using the NHS; you just choose where. Waits are usually months, not years.

How to use it:

1. Ask your GP for a "Right to Choose referral to [provider]" — bring the provider's referral form.
2. Provider assesses you (NHS-funded).
3. If diagnosed, NHS-funded treatment continues.

This is currently the fastest free route for most adults in England. (Right to Choose is England-only; Scotland, Wales and Northern Ireland have different rules.)

Route C — Private assessment

Cost: typically £500–£1,500 for a one-off psychiatric assessment, plus ongoing costs for follow-up and medication. Pros: fast (often weeks). Cons: ongoing private prescriptions can be expensive, though many people can later move to an NHS Shared Care Agreement.

What to look for in a private provider:

A GMC-registered psychiatrist doing the assessment (not just a "coach")
A structured assessment (e.g. DIVA-5)
A written report your GP will accept
Realistic medication and Shared Care information up front

What happens after diagnosis?

You'll get a written report. Treatment usually combines:

Medication (stimulants like methylphenidate or lisdexamfetamine; non-stimulants like atomoxetine)
Psychological support / coaching
Workplace and academic adjustments under the Equality Act 2010
Lifestyle scaffolding (external-brain systems, body doubling, routines)

Shared Care Agreements — the medication question

Most adults end up on medication. With a Shared Care Agreement, your psychiatrist (NHS or private) writes the initial prescription and titration; once you're stable, your GP takes over prescribing long-term. Not all GPs accept Shared Care from private providers — worth asking your surgery before paying privately.
