How to get an ADHD diagnosis as an adult in England

Last reviewed October 2026 · England only

GPs don't diagnose ADHD. Your GP refers you to a specialist, and in England you can choose which NHS-contracted provider does the assessment, using Right to Choose.

Who can diagnose ADHD

Under NICE guideline NG87 on ADHD, ADHD should be diagnosed by a specialist psychiatrist or another appropriately qualified healthcare professional with training in ADHD. A diagnosis needs a full clinical assessment, not just a questionnaire.

What a specialist looks for

The steps

  1. Write down your evidence. Main difficulties, since when, and where they cause problems. Old school reports and a family member's account help. The free evidence organiser does this with you.
  2. Choose a provider. Check they hold an NHS contract and can take referrals from your area now. See what to check.
  3. See your GP with your referral letter and the provider's form.
  4. Complete the provider's questionnaires quickly when they arrive. Late forms are a common cause of delay.
  5. Attend the assessment, usually a long online or face-to-face appointment.
  6. After diagnosis, discuss treatment options, which may include medication and support.
You can ask your employer for reasonable adjustments while you wait. You don't need a diagnosis to ask.
