Face to face appointments at our Chelmsford clinic

The Autism Service has been delivering autism and ADHD assessments for both children and adults since 2019.

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.

In 2025, The Autism Service will launch its Chelmsford clinic; one of three clinics in Essex. We will be able to increase regional capacity and carry out hundreds of assessments with our full range of assessments available. We are able to carry out assessments for both autism & ADHD as well as combinations of the two. Crucially, all assessments are available for both children and adults.

Our clinicians deliver fast, accurate diagnostic assessments to identify whether an individual has ASD or ADHD.
