ADHD and autism

An assessment that
does not end at the
diagnosis.

Adults and young people · By secure video · No GP referral needed

Assessed by a consultant psychiatrist or consultant paediatrician on the GMC Specialist Register. £650 for the first hour, which comes off the price of a full assessment if you go ahead. Then the part most clinics leave you to sort out yourself: the dose, the letter to your GP, and someone still prescribing if they say no.

Start here

One hour with a consultant to work out whether a formal assessment is the right next step, and which one. Deducted in full from an assessment booked within 3 months.

Initial assessment

£650 60 minutes

An hour with a consultant to establish whether a formal assessment is the right next step, and which one.

  • A written summary you keep, whatever we conclude
  • Deducted in full from a diagnostic assessment booked within three months

How it works.

You complete the questionnaires online — a structured diagnostic interview, a childhood account, and the health and impairment history. The consultant reads them before the appointment rather than working through them during it, which is what makes an hour enough.

Adults

Every assessment includes the written report. Fees are for secure video; in person in London is available and quoted when you book.

Frequently Asked Questions

At The Wellness the initial assessment is £650 for an hour with a consultant, and it comes off the price of a full assessment booked within three months. A full adult ADHD assessment is £950 and an assessment for an under-eighteen is £1,450, each including the written report. Across the UK assessments run from about £400 to £1,500. Ask any provider what happens after the diagnosis before you compare prices — titration and prescriptions usually cost more than the assessment did.

Often, but no one can promise it. Shared care is voluntary and your GP is not obliged to enter into it, and some practices and some areas decline all new agreements regardless of the assessment. What we can do is write the letter to your own integrated care board’s guidance, which is what most refusals turn on. If your GP declines, we continue prescribing rather than leaving you to find someone who will.

They have to consider it. The SEND Code of Practice is clear that a local authority cannot reject a professional report solely because it was obtained privately. What they can question is the quality, so reports for under-eighteens are written to be read by a school and a local authority as well as by a doctor, with the history, the impairment across settings and the reasoning set out rather than a conclusion on its own.

No, and the national guidance says so explicitly — a diagnosis must not rest on a rating scale alone. The assessment here uses a structured diagnostic interview against DSM-5 criteria, a corroborating account of childhood symptoms, and evidence of impairment in more than one setting. The questionnaires you complete beforehand inform that interview; they do not replace it.

No. You can book the initial assessment directly. Bring any previous reports or letters if you have them, because they carry history the consultant would otherwise have to reconstruct.

Yes. The transfer of care appointment is £395 and exists for this. Your existing report and prescription are reviewed, the physical health checks are brought up to date, and prescribing continues without a gap. Bring the original diagnostic report if you still have it.

No referral is needed and there is no waiting list. If you are already diagnosed and stranded because a previous provider stopped prescribing, the transfer of care appointment is the one you want.
