Who Are Our London ADHD ASSESSMENTS FOR?
Who Are Our London ADHD ASSESSMENTS FOR?
Private ADHD assessments in London are for adults who want a thorough clinical evaluation from a qualified doctor, without waiting years for an NHS appointment.
NHS ADHD services across London are delivered through several trusts, with Central and North West London NHS Foundation Trust covering much of central and west London. Waiting times from GP referral to first ADHD clinic appointment across London trusts have been consistently high, with patients commonly waiting two years or more. For many working professionals in London, that wait is not a realistic option when ADHD is affecting performance at work, relationships or daily functioning.
Our London ADHD assessments are suitable for:
- Adults who have suspected ADHD for years but have never been formally assessed.
- Professionals whose ADHD symptoms are affecting their performance at work.
- Those referred by a London GP but facing long NHS waiting lists.
- Adults who need a written ADHD report for an employer or occupational health.
- People seeking a medico-legal cognitive or ADHD assessment report.
- Those already diagnosed privately who want medication initiated or reviewed.
At the end of your assessment, your doctor will give you a clear diagnosis and a plan for next steps, including medication where clinically appropriate.
What Your London ADHD ASSESSMENT COVERS
What Your London ADHD ASSESSMENT COVERS
Your ADHD assessment at our Marylebone clinic is a structured clinical appointment with an experienced private doctor. The appointment runs considerably longer than a standard GP slot and follows a recognised diagnostic process aligned with NICE guidelines for adult ADHD.
Your doctor will begin by taking a detailed history of your symptoms, how long you have experienced them and how they affect your daily life and work. They will explore whether symptoms were present before the age of 12, as required under NICE criteria.
Your doctor will then use validated clinical tools. These include the DIVA 2.0 structured diagnostic interview and the Conners Adult ADHD Rating Scales, which assess inattentive, hyperactive-impulsive and combined ADHD presentations across both adult and childhood domains.
Your doctor will also consider conditions that can present alongside ADHD or mimic its symptoms, including anxiety, depression, sleep disorders and autism, and will factor these into their assessment.
By the end of the appointment, you will have a clear diagnosis and a plan for next steps. If ADHD is confirmed and medication is clinically appropriate, your doctor can issue a private prescription at the same visit. You can also arrange formal written reports for employers, occupational health, legal proceedings, or professional bodies.
Private vs NHS ADHD ASSESSMENT IN LONDON
Private vs NHS ADHD ASSESSMENT IN LONDON
NHS ADHD waiting lists across London are among the longest in England. Demand across Central and North West London NHS Foundation Trust and other London trusts is consistently high, and patients typically wait two years or more from GP referral to first ADHD clinic appointment. For London professionals managing careers, mortgages and family responsibilities, that wait often means years of avoidable difficulty.
Private ADHD assessment in London gives you access to a qualified doctor within days at our Marylebone clinic. Your assessment meets the same clinical standards as an NHS assessment and follows NICE guidelines for adult ADHD diagnosis.
A private ADHD diagnosis from our London clinic is accepted by most NHS GP practices for shared care, allowing your GP to take over prescribing of ADHD medication on the NHS once our doctor has initiated it. We recommend confirming this with your GP before booking.
If you need a written ADHD report for an employer, occupational health, an insurance matter, a professional registration body or legal proceedings, your doctor can provide one. This is a common requirement for London patients and can be arranged at the same appointment.
Most major health insurance policies cover private ADHD assessments. Self-paying patients do not need a referral to book.
