Private adult ADHD assessment cost in the UK: 2026 price guide

A private adult ADHD assessment is a structured clinical interview, with questionnaires and sometimes information from family or school, carried out by a psychiatrist or other qualified clinician to decide whether symptoms meet criteria for ADHD.

Published guide prices for adult ADHD assessment ran from £180 to £950 in the hospital price lists we retrieved. They are not quotes: each provider decides what its figure includes, and the final price follows assessment.

These are published guide figures from October 2026 and can change. Use them to judge scale, and rely on an itemised written quote for your own circumstances.

The clinician takes a detailed history of attention, impulsivity and restlessness from childhood onwards, often supported by rating scales and sometimes information from someone who knew you as a child. A diagnosis is made if criteria are met and symptoms cause impairment.

Ask what the price covers after the first appointment, how medication would be managed and whether your GP is likely to accept shared care, because that is where long-term costs arise.

If two quotes for adult ADHD assessment differ, the reasons are usually found in the list below rather than in the headline name of the procedure.

• Provider type and clinician: a consultant psychiatrist assessment costs more than some other models, and Psychiatry-UK lists an adult ADHD initial assessment at £950 with a one-hour online consultant appointment.

• What is included in the fee: the same provider lists follow-up to complete the assessment, reports and letters at no extra charge, but other providers charge for them.

• Medication follow-up: starting treatment involves a separate titration phase, and a 12-week titration package is listed at £750 at that provider.

• Review appointments: £180 per review at that provider, and longer reviews cost more.

• Shared care: whether your GP agrees to take over prescribing, which affects ongoing private prescribing costs.

Before comparing totals, compare contents. These are the lines most often included, and the ones most often added afterwards.

Insurers vary on ADHD assessment, and many exclude neurodevelopmental conditions or pay only for specific providers, so check wording before paying.

Authorisation from the insurer before the date is the safest course, and it is worth asking what happens if the plan changes on the day. Self-pay patients may be able to spread the cost, though any finance is a credit agreement.

In England patients can use the NHS Right to Choose to request an assessment from an approved provider at no cost, though waiting lists vary, and local NHS ADHD services may have long waits.

The NHS sets an 18-week standard from referral to treatment for non-urgent consultant-led care, and in England you have a legal right to choose a provider. Waiting times differ by area and specialty, so ask your GP or the provider about current local waits rather than relying on a national average.

There is no physical recovery. If medicines are started, a period of monitoring and adjustment follows, and the cost is mainly in the follow-up appointments and prescriptions.

Complications are uncommon for most patients, yet a quote should say what happens if something does not go to plan.

• A diagnosis does not guarantee an NHS GP will agree shared care, so some people continue to pay privately for prescribing and reviews, and the long-term cost can exceed the assessment fee.

• Assessments vary in quality, so check that the clinician is registered, that the process follows recognised criteria and that the report is likely to be accepted by your GP or employer.

A lower headline figure can hide extras. Use these questions to make quotes for this procedure comparable.

• Is the fee for a consultant psychiatrist assessment and does it include the report?

• What would medication titration and reviews cost?

• Will you support shared care with my GP?

• How many appointments are likely before a diagnosis?

• Which fees are fixed in the written quote, and which, such as consultant or anaesthetist fees, might be billed separately?
