ADHD assessment, testing and diagnosis in London: the local picture
Adult ADHD assessment is delivered by several NHS mental-health trusts across London, including South London and Maudsley, Camden and Islington (NELFT), and Barnet, Enfield and Haringey. NHS waits for assessment in London have been widely reported as long, and Right to Choose referrals to private providers under NHS funding are commonly used in the capital. Current NHS waits change frequently — check your local trust's website for the latest figure. The list below shows providers operating in London in person and UK-wide online services that London patients regularly use.
People search for this in different ways — an ADHD test, online ADHD testing, an adult ADHD diagnosis, or an ADD assessment (the older name). In practice these all point to the same thing: a structured diagnostic assessment with a qualified clinician. That is what every provider listed below offers people in London, online or in person.

ADHD assessment in London — frequently asked questions
How long is the NHS ADHD assessment waiting list in London?
NHS adult ADHD assessment waits in London have been widely reported as long — often measured in years rather than months — and vary by trust. Because waits change frequently, check your local NHS trust's website (e.g. South London and Maudsley, Camden and Islington, Barnet Enfield and Haringey) for the current figure before deciding between NHS, Right to Choose and private routes.
Where are the main private ADHD clinics in London?
Most in-person clinics cluster around Harley Street and the City, with newer providers operating from clinics in Canary Wharf, Shoreditch and South London. Many providers are now online-first and only see patients in person when clinically necessary.
Will my London GP do shared care after a private ADHD diagnosis?
Some London PCNs and individual GPs accept shared care agreements with private ADHD providers; others have a blanket policy not to. We flag shared care availability per provider above. Always confirm with your GP before booking, as their answer determines your ongoing medication cost.
Can I use Right to Choose from a London GP?
Yes — patients registered with an NHS GP in England (including London) can use Right to Choose to be referred to certain private providers under NHS funding. Wait times under Right to Choose vary by provider and have lengthened considerably in 2024–25.
Is it cheaper to be assessed for ADHD in London or elsewhere in the UK?
Online providers charge the same fee regardless of where you live. In-person London clinics tend to sit at the higher end of the price range. Compare current prices side by side using the table above.
Is an ADHD test the same as an ADHD assessment?
Mostly, yes — "ADHD test" is the everyday phrase, and clinics call it a diagnostic assessment. A free online ADHD test or screener (a short questionnaire) can suggest whether a full assessment is worth pursuing, but it cannot diagnose you. Only a diagnostic assessment with a qualified clinician — online or in person — can do that, and that is what the providers on this page offer people in London. ADD is simply the older name for what is now diagnosed as ADHD, most often the inattentive type.
