London has the highest concentration of private ADHD clinics in the UK, with most offering appointments within 2–4 weeks. Prices range widely — from under £700 at newer clinics to over £2,000 at Harley Street practices. The majority are CQC-registered and offer NHS Shared Care agreements, meaning your GP can take over prescribing after diagnosis.
