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 in most areas now run 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 typically cost between £400 and £1,500 depending on the provider, 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 4 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.

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.
