Private autism & ADHD assessments in our Chelmsford clinic
The Autism Service has been delivering autism and ADHD assessments for both children and adults since 2019. Our aim is simple: to make high-quality, face-to-face assessments more accessible across the UK.
With over 700,000 people living with autism across the UK, we recognised the need to supply face-to-face appointments at more locations. Waiting months for an autism diagnosis can be stressful and opening our Chelmsford clinic means private assessments are now more readily available in Essex.
Since launching in 2025, our Chelmsford clinic has significantly increased local assessment capacity, completing hundreds of assessments for both children and adults. We offer autism, ADHD and combined assessments for both Children and Adults, all delivered by experienced clinicians
Our Chelmsford-based team provides timely, thorough diagnostic assessments, helping individuals gain clarity, understanding, and the right support moving forward.
