Private Autism Assessments in Cardiff

NICE-Compliant Autism Diagnosis for Children & Adults

Looking for a private autism assessment in Cardiff? Jo Condon Autism Assessments delivers thorough, NICE-compliant autism assessments for children aged 2+ and adults from our central Cardiff clinic on Charles Street, just off Queen Street.

Cardiff and the wider South Wales region face some of the longest NHS autism assessment waits in the UK — Cardiff and Vale University Health Board has reported diagnostic waits of around 26 months, with rural Welsh waits reaching well over three years. Our private pathway is designed to give Cardiff families and adults a faster, clearer route to a formal diagnosis without compromising clinical depth.

Our experienced clinicians serve clients from across Cardiff, the Vale of Glamorgan, Penarth, Rhondda Cynon Taf, and Bridgend.

Every assessment at our Cardiff clinic is carried out by senior, UK-registered clinicians with extensive experience in autism diagnosis across childhood and adulthood. Our team is trained in the ADOS-2 and a full range of supporting diagnostic tools, and works to the same NICE-compliant standards used by Cardiff and Vale’s Integrated Autism Service.

We work hard to make the experience of being assessed feel humane and unhurried. For many of the adults we see in Cardiff, this is the first time they have had an extended conversation with a clinician about their own experience of the world. Our role is to listen carefully, observe with rigour, and offer a clear, evidence-based view at the end of the process.
