Face to face appointments at our London clinic

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

With over 88,000 people living with autism in London alone, 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 London clinic means private assessments are now more readily available.

Since opening our Marylebone clinic, we’ve been 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.
