A complete breakdown of private ADHD assessment costs in the UK in 2025 — what's included, how to compare clinics, and how to avoid hidden fees.
If you're considering a private ADHD assessment in the UK, cost is almost certainly one of your first questions. Prices vary more than you might expect — and not always in ways that reflect quality. This guide breaks down exactly what you should expect to pay, what's included, and how to make sure you're not caught out by hidden fees.
For adults, private ADHD assessments in the UK currently range from around £495 to £1,200, with the national average sitting at approximately £700–£900 for a comprehensive assessment.
The wide range reflects several factors: location (London clinics tend to charge more), whether the assessment is online or in-person, the seniority of the assessing clinician, and what's included in the package.
Online vs in-person: Online assessments (conducted via video call) are typically 10–15% cheaper than in-person assessments at equivalent clinics. The quality of the clinical assessment is not meaningfully different — online ADHD assessments are fully legitimate and widely accepted by GPs and employers.
A thorough ADHD assessment should include all of the following — check carefully before booking whether any of these are listed as extras:
For many people, the initial assessment is just the beginning of the financial picture. If you're diagnosed with ADHD and want to try medication, be prepared for:
Titration: This is the process of finding the right medication and dosage for you. It involves regular appointments — typically every 3–4 weeks — until your medication is stabilised. Each appointment typically costs £80–£200. Most people need 3–6 titration appointments.
Prescriptions: Private ADHD medication prescriptions typically cost £15–£30 per prescription, plus the medication itself. ADHD medications are not currently available free on a private prescription — however, if your GP agrees to shared care, they'll take over prescribing via the NHS, meaning you pay only the standard NHS prescription charge (currently £9.90 per item, or free if you hold a prepayment certificate).
Shared care — the most important question to ask: Before you pay for any private assessment, ask your GP whether they will agree to shared care if you're diagnosed. Some GPs refuse, and if yours does, you'll be paying private prescription costs indefinitely. Getting clarity on this upfront could save you thousands.
Not necessarily. Price reflects many factors beyond clinical quality — overheads, location, marketing spend, and the seniority of the assessing clinician. A £595 online assessment from a CQC-registered clinic with GMC-registered psychiatrists can be every bit as thorough as a £1,200 in-person assessment in Harley Street.
What matters more than price:
Right to Choose (England only): If your GP refers you for ADHD assessment, you have the right to choose any NHS-contracted provider — including some private clinics like Psychiatry UK and ADHD 360. If this route is available to you, it means a private-standard assessment at no personal cost. Ask your GP specifically about Right to Choose.
Health insurance: Most standard UK health insurance policies do not cover ADHD assessments as standard, but some policies do. Check your policy documents or call your insurer directly.
Employer occupational health: Some larger employers will fund an assessment through occupational health, particularly if ADHD is affecting your work performance. Worth asking your HR department.
