Adult autism assessments

Autistic brains work differently, affecting how people communicate and interact with the world around them. For many, a diagnosis is a long-overdue validation for feeling different. It can provide clarity, belonging, peace of mind and support.

Yes, as long as your GP provides us with a referral. More information can be found on our Right to Choose page.

Our autism assessment process combines a series of pre-assessment questionnaires with the most trusted, accurate, and widely used diagnostic procedures. Using these tools together helps us provide the most accurate diagnostic decisions and make detailed recommendations.

Where possible, we collect information about your childhood experiences and adulthood from someone who has known you from an early age. This person is referred to as your "informant". Their role is to support your assessment by completing a detailed and attending a diagnostic interview called the ADI-R.

You will also be asked to complete pre-assessment questionnaires and attend your assessment with a specialist clinician matched to your specific requirements. You will then have a feedback appointment to review your results and discuss your next steps.

For more information, please read our adult autism assessment guide.

There are six questionnaires to complete before your appointment. Please ensure you use these to provide as much detail as possible, with specific examples where possible.

  • Your informant's appointment can take up to three hours
  • Your ADOS-2 appointment will last up to 90 minutes
  • Your feedback appointment will be 30 minutes long

Our assessments are all conducted by senior neurodevelopmental specialists with many years of experience assessing and diagnosing autism. We will send you details of your clinician before your assessment.

Our adult autism assessments cost £2250.

In most cases, a GP referral isn't necessary. However, we will let you know if we do need to see one, or any other information, before determining if we are an appropriate service for you.
