Written by: Dr Rano Bhadoria, Consultant AdultPsychiatrist, Private Medical Clinic

At Private Medical Clinic, a private ADHD assessment costs £950 for an adult and £1,295 for a child. This includes thefull clinical process, not just the appointment, screening questionnaires, adetailed interview with a psychiatrist or psychologist, and a written report with a diagnosis and treatment recommendations. Medication titration and follow-up appointments, if you’re prescribed treatment afterwards, are arranged and charged separately.

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

Independent research comparing 41 UK ADHD assessment providers found prices ranging from £289 to£2,240, with a median of £950 — so PMC's adult assessment sits right at the reported market median, not at either extreme. The gap between providers usually comes down to three things: whether QbCheck computer-based testing isincluded, whether a consultant psychiatrist writes the report rather thananother clinician, and whether medication titration is bundled in or billed as a separate service.

What’s included in the Private Medical Clinic price?

The £950 adult fee covers pre-assessment screening questionnaires, a clinical interview with a psychiatrist or psychologist, optional QbCheck computer-based testing, screening for commonly overlapping conditions such as anxiety or autism, a complete written report setting out the diagnosis andtreatment recommendations, and a follow-up feedback session to talk through theresult. It does not include medication.

Are there additional costs?

Yes, if a diagnosis leads to a medication recommendation. Titration,the process of finding the right dose, along with the review and follow-up appointments that go with it, is arranged as a separate service once adiagnosis is confirmed, and isn’t part of the initial £950 or £1,295 fee. If your assessment identifies a second condition that needs its own separate assessment, that would also carry its own cost.

Why do private ADHD assessment costs vary so much?

The £289–£2,240 range reported across UK providers largely comesdown to three things: who’s doing the assessing (a consultant psychiatrist’s time costs more than a psychologist’s or a nurse specialist’s), whether objective testing like QbCheck is included alongside the clinical interview,and whether the price bundles in the follow-up feedback session and post-diagnosis support or charges for these separately. A lower headline priceis often narrower in scope, so it’s worth checking exactly what’s included before comparing two prices side by side.

How does this compare with the NHS?

An NHS ADHD assessment itself is free, funded through general taxation rather than paid for directly. What it costs instead is time: BBC Newsreporting has found that adults referred for an NHS ADHD assessment arecurrently waiting an average of 618 days from referral to being seen. A private assessment doesn’t skip clinical rigour, it follows the same diagnostic criteria, but it removes that waiting list entirely, which is the main reason people choose to pay for one.

What happens during a private ADHD assessment?

You’ll first complete screening questionnaires covering your history and current symptoms. This is followed by a detailed clinical interview with a psychiatrist or psychologist, who may also use QbCheck, a computer-based testt hat measures attention, impulsivity and activity levels objectively along side the interview. The clinician then screens for commonly overlapping conditions,since anxiety, autism and mood disorders often present alongside ADHD and canaffect the picture. You receive a full written report setting out the diagnosisand treatment recommendations, followed by a feedback session to go through itwith you.

Who may consider a private ADHD assessment?

People who suspect they or their child may have ADHD and don’t want to wait well over a year for an NHS assessment are the most common reason we see. It’s also a reasonable option for adults who were never assessed aschildren and want clarity now, or for anyone whose current NHS assessment hasstalled and who wants a second, faster route to a diagnosis.

Is a private ADHD assessment worth the cost?

That depends on what you’re weighing it against. You’re paying fortime, typically an assessment within days or weeks rather than well over 618 days, and for a comprehensive, all-inclusive process rather than a bare-minimum interview. It isn’t a shortcut to a more favourable diagnosis; the clinical criteria are identical to the NHS. For someone who needs an answer now, whetherfor work, education or simply their own wellbeing, most people find that trade-off reasonable. For someone with no urgency, waiting for the NHS routeremains a valid, free option.
