Private autism assessments in our Sussex 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 Sussex clinic means private assessments are now more readily available across the South East.

Since launching our Sussex clinic in 2022, we’ve been able to increase regional capacity and carry out hundreds of assessments. Currently, we’re only carrying out autism assessments although these are available for both adults and children.

If you require an ADHD or combined assessment, please book at one of our other locations. Our Surrey clinic in Guildford is currently our closest clinic that carries out both pathways.

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

All the staff and clinicians were very friendly and put you at your ease. The whole process was so reassuring and you were made to feel comfortable at all times.

I would highly recommend The Autism Service. Everyone we had contact with was incredibly kind, understanding, empathetic and very helpful. They responded to emails almost immediately, which made the whole process much less stressful for us. My daughter usually does not like talking on the phone or online, but she felt comfortable and opened up during the appointments. She was happy to answer questions, which shows that the staff truly know how to approach and support their patients. Even after the assessment was completed, they continued to be helpful and supportive. We are very grateful for their professionalism and care. I highly recommend this service.

Such a positive experience from start to finish. We had been waiting three years for an NHS Assessment and decided to go private for our daughter. From the start, there was a detailed plan in place. I knew what was going on at every stage and the whole process was quick and well informed. We have finally been listened to and have a report that helps us to provide the help and guidance our daughter deserves. Thank you!

For a long time we struggled with our son and just knew there was something different about him. After being told NHS waiting times were over 24 months, we felt we had no choice but to go private for the sake of our 9-year-old. At that point, he would have been starting secondary school before we even received a diagnosis, and he was already struggling. As parents, we felt it was our duty to get answers sooner rather than later. Choosing The Autism Service was honestly the best decision we could have made. From start to finish the whole process was smooth, professional, and well communicated. We felt listened to, supported, and reassured every step of the way. I would highly recommend this service to any parent in a similar position.
