Average Private ADHD Assessment Costs in 2026

Based on data from providers listed on ADHD Map and national research, typical private ADHD assessment costs in 2026 are:

  • Online-only assessment (video call): £350–£600. Usually the cheapest option. Assessment is conducted by a psychiatrist or nurse prescriber via secure video.
  • Face-to-face assessment at a clinic: £500–£1,000. Includes an in-person consultation at a clinic, typically lasting 1.5–3 hours.
  • Comprehensive assessment with full report: £800–£1,500. Includes a detailed written report suitable for employers, universities, or Access to Work applications.
  • Combined ADHD + Autism (AuADHD) assessment: £1,800–£2,600. Covers both conditions using gold-standard tools like DIVA, ADOS-2, and ADI-R.
  • Child ADHD assessment: £800–£1,800. Higher cost reflects additional informant interviews (parents, teachers) and play-based observation.

What Is Included in the Assessment Fee?

Not all assessments include the same things. Before booking, confirm exactly what your fee covers:

  • Pre-assessment screening questionnaires (ASRS, DIVA) — usually included.
  • The diagnostic interview itself (1–3 hours) — always included.
  • A written diagnostic report for your GP — usually included, but sometimes an extra £50–£150.
  • A letter to your GP recommending shared care — usually included.
  • Informant interview (partner, family member, or friend) — varies; some providers charge extra.
  • QB test (objective ADHD measure) — often £200–£300 extra if required.
⚠️
Important

The assessment fee almost never includes medication titration. Titration typically costs an additional £300–£500 and is a separate process after diagnosis. Always ask about total pathway costs, not just the assessment fee.

Hidden Costs After Your Assessment

The assessment fee is just the start. Budget for these common follow-up costs:

  • Medication titration: £300–£500 (4–8 review appointments at £75–£150 each).
  • Private prescriptions during titration: £15–£30 per prescription plus the cost of medication itself.
  • Annual review with your specialist: £150–£300 per year if your GP does not take over.
  • Private medication costs if GP refuses shared care: £60–£120 per month depending on the drug and dose.
  • Additional reports (for employers, DVLA, universities): £50–£200 per report.

How to Get Assessed for Free via Right to Choose

If you are registered with an NHS GP in England, you may be able to access a free ADHD assessment through the NHS Right to Choose. This is a legal right that allows you to choose an approved private provider for your assessment — at NHS cost.

Wait times via Right to Choose are typically 2–12 weeks, compared to 3–7+ years on many NHS waiting lists. The assessment is clinically identical to a private assessment.

Use our provider finder to filter by "Accepts NHS Right to Choose" and find approved providers in your area. This is the most cost-effective route for most patients.

Regional Price Differences

Private ADHD assessment costs vary significantly by region. London and the South East tend to be the most expensive, while online-only providers and those based outside major cities often charge less.

In the East of England — the region covered by ADHD Map — we have found assessment costs ranging from £395 (ADHD Norfolk screening) to £1,800 (Cambridge Adult ADHD & ASD Clinic full assessment). Online providers accepting patients nationally typically charge £450–£800.

How to Choose a Provider Based on Value

The cheapest assessment is not always the best value. Consider:

  • Is the provider CQC-registered? This is essential for your diagnosis to be accepted by the NHS.
  • Does the fee include a GP report? Without this, you cannot request shared care.
  • What is the total pathway cost (assessment + titration + first year of medication reviews)?
  • Does the provider accept Right to Choose? If so, the assessment is free.
  • What are reviews from other patients like? Check our provider profiles for ratings and wait time reports.

Frequently Asked Questions

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

Typical costs in 2026 range from £350 for a basic online assessment to £1,500+ for a comprehensive assessment with a full written report. Combined ADHD and Autism assessments cost £1,800–£2,600.

Can I get an ADHD assessment for free?

Yes — through your NHS GP (wait times vary from months to 7+ years depending on your area) or through the NHS Right to Choose scheme, which lets you choose an approved private provider at no cost. Wait times via RTC are typically 2–12 weeks.

What is the cheapest private ADHD assessment?

Online-only assessments start from around £350. Some providers in the East of England offer screening assessments from £395. However, always check what is included — the cheapest option may not include a full diagnostic report or GP letter.

Does the assessment fee include medication?

No. The assessment fee covers diagnosis only. Medication titration (finding your optimal dose) is a separate process costing £300–£500 additionally. Ongoing medication costs depend on whether your GP accepts shared care.

Is a private ADHD assessment worth it?

For many patients — yes. NHS waiting lists can exceed 3–7 years in many areas. A private assessment gives you answers in weeks and enables access to medication and workplace support much sooner. The total cost including titration is typically £800–£1,500.

What is the difference between screening and full assessment?

A screening (£250–£400) is a preliminary evaluation that indicates whether ADHD is likely. A full diagnostic assessment (£500–£1,500) is conducted by a qualified specialist and results in a formal diagnosis that your GP and other professionals will accept.
