Your local autism assessment options in London
London has more independent autism assessment capacity than anywhere else in the UK, which makes it one of the few places where choosing between providers is a real decision rather than taking whoever is available. That choice matters more for autism than for ADHD: providers differ in whether they use ADOS-2, ADI-R or an interview alone, whether they gather informant history, and whether a written report is included or charged separately. NHS waits for adult autism assessment commonly run to years.
