What affects the cost?
Location
Prices differ by region. The Price Index shows the average starting price for each region. Online-only providers often charge less regardless of location.
Appointment length
A full ADHD assessment usually takes 2–4 hours across one or more sessions. Shorter assessments cost less but may not be accepted for prescribing or insurance purposes.
What's included
Some prices include a full written report and GP letter; others charge extra. Always confirm what's included before booking.
Clinician type
Assessments conducted by a consultant psychiatrist cost more than those by a specialist nurse or psychologist. Psychiatrist-led assessments can directly prescribe medication.
Follow-up care
Some clinics include medication management and follow-up appointments in the initial price. Others charge separately for titration and ongoing care.
