About ADHD assessments in London
If you're looking for an ADHD assessment in London, you have two main routes: private assessment or the NHS. NHS waiting lists vary widely by area, from months to several years, which is why many people choose to pay privately or use the NHS Right to Choose scheme to access a private provider at no cost.
Private ADHD assessments in London vary by provider, depending on the length of the assessment, and whether it's conducted by a psychiatrist or a specialist nurse. See our full ADHD assessment cost guide for a detailed breakdown. Online assessments are generally cheaper than in-person appointments and are equally valid.
Women with ADHD are often diagnosed much later than men due to different symptom presentations. If you think your ADHD may have been missed or misdiagnosed, read our guide on ADHD in women and why it's often missed.
Some clinics in London offer combined ADHD and autism assessments — a single process that evaluates for both conditions simultaneously. This is often quicker and more cost-effective than two separate assessments. Use the Combined ADHD & Autism filter above to see these providers.
London has 6 Right to Choose providers listed above. If you're registered with a GP in England, ask your GP to refer you under the Right to Choose scheme — the assessment is funded by the NHS at no cost to you. See our Right to Choose guide for the full process.
Frequently asked questions about ADHD assessments in London

How long is the wait for an ADHD assessment in London?

Right to Choose clinics also tend to have shorter waits than the standard NHS pathway. Use the 'Wait ↑' sort above to find the fastest options.
What happens at an ADHD assessment?
A comprehensive ADHD assessment usually involves a detailed clinical interview covering your symptoms, history, and daily functioning. The clinician may ask you to complete standardised questionnaires (such as the Conners or DIVA). Some assessments include input from a third party (such as a parent or partner). At the end, you will receive a diagnosis and, if appropriate, recommendations for treatment.
Are online ADHD assessments valid in London?
Yes. Online ADHD assessments carried out by CQC-registered clinicians are clinically valid and can be used for diagnosis, prescribing, and workplace/educational adjustments. Several providers listed above offer online-only assessments, which are often more affordable and have shorter wait times.
