ADHD & Autism Assessment Providers in London
London has the largest concentration of ADHD and autism assessment providers in the UK, with dozens of CQC-registered clinics operating across the capital. Both NHS Right to Choose and private assessment routes are available. Right to Choose wait times in London vary significantly by ICB — some boroughs have wait times of 12–18 weeks, while others may be longer.
