Home Assessments Adult autism assessment
Adult autism assessment
A full diagnostic assessment for adults using the ADI-R and ADOS-2, the same standardised tools used in NHS autism services. We take particular care with masked and less typical presentations. Every assessment is independently reviewed, and you receive a co-signed report and a feedback session.
Adults (18+) only. We provide diagnosis only, not medication.

Two clinicians, not one
Your assessor carries out your screening, history and live diagnostic interview. Your independent psychologist is a fully qualified, HCPC-registered Clinical or Educational Psychologist. They review your full file, check it against diagnostic criteria and co-sign your final report.
Every diagnosis is independently verified before it reaches you. How it works

Report & feedback
Report + feedback sessionYou receive your co-signed written report and a feedback session where everything is explained in plain language.
Before you book: the informant interview
The ADI-R needs an interview with someone who knew you well as a young child – usually a parent – lasting around 2–3 hours. If no informant is available, please mention this on your initial call. We can discuss whether an assessment is still possible and what it would involve.
Is it right for you?
Who this assessment is for
Designed for you if…
- You're an adult (18+) seeking a formal autism diagnosis
- You've been on an NHS waiting list, or want to avoid joining one
- You have someone who can complete the informant interview
- You want a report you can share with your GP, employer or university
It may not be the right fit if…
- You're under 18 – we assess adults only for now (children's autism assessments will follow our children's ADHD service in 2027)
- You're in crisis or need urgent mental health support
- You're looking for ongoing therapy rather than assessment
Not sure? That's what the free initial call is for, and there's no obligation to continue afterwards.
An alternative to the NHS wait
In Kent and Medway, routine NHS Right to Choose autism assessments have been put on hold after the local budget ran out. They're not expected to restart before April 2027, and then there's a backlog. A self-funded assessment gives you a route to diagnosis on your own timeline. Read the full Right to Choose update
