With NHS waiting times for ADHD assessment remaining lengthy in many parts of England, more people are weighing up a private diagnosis. For most, one of the first questions is a practical one: how much does a private ADHD assessment cost in the UK?
The answer depends on the provider, the age of the patient, whether the assessment takes place online or in person and what is included in the fee. The cost of a private ADHD diagnosis in the UK also rarely ends with the assessment itself, as medication, follow-up appointments and ongoing prescribing can add considerable cost to the total.
Based on prices published by providers and reviewed by Medical Travel Market in November 2026, adult assessments at the established clinics we looked at range from £695 to £950 for an online appointment. In-person appointments and faster-track pathways can cost considerably more.
How much is a private ADHD assessment in the UK?
Published prices vary considerably between providers.
For example, Private ADHD charges £795 for an adult assessment and £900 for a child assessment, while Clinical Partners charges £895 for adults and £995 for children. Psicon lists £950 for an adult assessment and £1,200 for a child assessment, and Psychiatry UK’s private adult service is also £950.
ADHD 360 offers an Essential assessment from £795, while its faster Comprehensive pathway, with an appointment within seven days, costs £1,550.
The ADHD Centre provides a useful example of how online and in-person ADHD assessment costs can differ. Its adult assessment costs £695 online and £1,095 in person, while child assessments are currently £1,395 online and £1,695 in person.
The table below illustrates the prices at some of the leading ADHD clinics in the UK.

| Psicon | £950 |
| Psychiatry UK | £950 |
Prices were checked in November 2026 and may change. Patients should always confirm the latest fee, and exactly what is included, directly with the provider before booking.

Why do private ADHD assessment costs vary?
Not all ADHD assessments are structured in the same way. Some providers operate predominantly online, while others offer face-to-face appointments. Fees can also vary according to the clinician carrying out the assessment, the length of the consultation, pre-assessment screening, the diagnostic tools used, the level of detail in the written report and whether follow-up appointments are included.
NICE guidance states that ADHD should be diagnosed only by a specialist psychiatrist, paediatrician or another appropriately qualified healthcare professional with training and expertise in diagnosing ADHD. The diagnosis should follow a full clinical and psychosocial assessment, including a developmental and psychiatric history, and should not be based solely on a questionnaire or rating scale.
What is normally included in the assessment fee?
A private ADHD assessment will generally involve pre-assessment questionnaires or screening, followed by a detailed clinical interview exploring symptoms and how they affect different areas of life. Developmental history, education, employment, relationships, mental health and other possible explanations for symptoms may also be considered.
Many providers include a diagnostic outcome letter or full written report within the fee. Policies on follow-up appointments differ. Psychiatry UK, for example, states that a follow-up appointment needed to complete the assessment is included in its £950 fee, while The ADHD Centre lists standard follow-up appointments separately at £225 for adults. It is important to check exactly what is covered.
It is also worth remembering that paying for an ADHD assessment does not guarantee an ADHD diagnosis. The purpose of the assessment is to establish whether someone meets the diagnostic criteria and whether other conditions or explanations need to be considered.
What does ADHD treatment cost after diagnosis?
The assessment fee may be only the beginning if treatment is required. If medication is recommended, patients may face additional costs for titration (the process of finding the right dose, which can take around 12 weeks), follow-up consultations, private prescriptions and the medication itself.
Providers structure these costs in different ways. Psychiatry UK lists a 12-week titration plan at £750, with medication and a blood pressure monitor charged separately. Psicon lists £995 for 12 months of prescriptions and clinically required review appointments, while Private ADHD charges £245 a month for titration appointments and £95 a month for repeat prescriptions once treatment is stable. ADHD 360’s Essential assessment and treatment package costs £1,585 when paid in full, with medication billed separately.
Taken together, an assessment and titration come to £1,700 at Psychiatry UK, while Psicon’s assessment and 12 months of prescriptions and reviews come to £1,945, in both cases before the cost of any medication.
The medication itself is usually charged separately, and providers rarely quote a fixed price for it. ADHD 360 and Psychiatry UK both state that the cost depends on the medication, the dose and the pharmacy, so patients should ask what to expect before committing to treatment.
It is therefore worth asking a provider about the likely first-year cost of assessment and treatment, rather than looking only at the initial assessment fee.
Will the NHS pay for medication after a private ADHD diagnosis?
Not automatically.
Some patients move to NHS prescribing through a shared care agreement once their medication has been started and stabilised by a private specialist. However, shared care is not guaranteed and a GP practice can decline the arrangement. NHS organisations therefore advise patients considering a private ADHD assessment to discuss shared care with their GP beforehand.
The difference in cost can be significant. If shared care is accepted, patients in England pay the standard NHS prescription charge, currently £9.90 per item unless they are exempt, alongside any annual review fee charged by the private provider. If it is declined, patients may need to keep paying privately for specialist reviews, prescriptions and medication. Psychiatry UK, for example, charges £25 per prescription plus a £180 annual review in that situation, with the medication itself an additional cost.
For eligible patients in England, Right to Choose is different from self-funded private treatment. It may allow a patient referred by their GP to access an independent ADHD provider through an NHS-funded pathway, meaning the patient does not pay privately for the assessment. Availability and waiting times can vary by area.
What should you ask before paying for an ADHD assessment?
Before booking your ADHD assessment, find out who will conduct the assessment and whether they are appropriately qualified to diagnose ADHD. Confirm whether the quoted fee includes pre-assessment screening, the diagnostic consultation, a written report and any follow-up appointments.
If medication may be required, also ask about titration, prescription and medication costs, and what happens if your GP does not accept shared care.
The headline assessment price is important, but the true cost of a private ADHD diagnosis in the UK depends on the complete pathway. Understanding both the initial fee and the potential cost of ongoing treatment can help patients make a more informed decision.
