Autism assessment for adults

At Neuroaffinity, we offer high-quality autism assessments for adults across the UK, online and in person.  If you’ve always felt “different,” struggled with social interactions, sensory overload, or maintaining routines and relationships, you may be wondering if autism could be the reason.

Our team of HCPC-registered clinicians provides compassionate, evidence-based adult assessments for autism designed to bring clarity and support, no matter where you are in life.

Why choose a private adult autism assessment?

Many people reach adulthood without ever receiving an autism diagnosis. Some may have spent years masking their traits, being misdiagnosed with anxiety or depression, or simply feeling misunderstood.

An assessment for autism in adults can offer important validation and a clearer understanding of yourself, your needs, and your strengths.

Choosing a private autism assessment for adults with Neuroaffinity means:

Whether you’re seeking a diagnosis for personal insight, workplace accommodations, or mental health support, your reason is valid, and we’re here to help.

What to expect from our adult autism assessment process

Our autism assessments for adults in the UK follow a clear, clinically rigorous process, while staying supportive and neurodiversity-affirming:

The autism assessment process includes several steps:

01

Initial screening

You’ll complete rating scales and questionnaires to evaluate autism symptoms and their impact. An assessment fee is charged only if you pass this initial screening.

02

Additional background information

Additional details may be gathered from family members or partners to gain a complete understanding of your symptoms.

03

Clinical interview

A specialist autism clinician will conduct a clinical assessment through a face-to-face consultation or via a video conference, which will last between 60 and 90 minutes. For adults, it is beneficial if a family member who has known them since childhood can be present during this assessment.

04

Observational assessment

A second face-to-face or video conference will be conducted, during which our specialists will observe how you interact in various settings. They will assess important aspects of communication, social skills, and repetitive behaviours. This evaluation may involve assessment tools like the ADOS-2 and can last up to 90 minutes.

05

Diagnostic decision and feedback

Based on the gathered information, a diagnostic decision will be made according to the criteria from the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This will be done at a separate feedback appointment.

06

Receive your report

Within 7 working days of your autism feedback appointment, you will receive a written report by email. This report will include the clinical diagnosis and, if applicable, a proposed treatment plan.

I cannot recommend this Neuroaffinity enough! My 7-year-old nephew is autistic and has mild ADHD, and this clinic has been a blessing for him and his young parents family. From the very first visit, the staff was warm, patient, and incredibly knowledgeable. They took time to understand his unique needs and created a personalised plan that helped with communication, sensory regulation, social skills, focus, and emotional regulation helping him to build the skills he needed. The therapists were amazing with him, and they also gave our family practical strategies to use at home. we’ve seen major improvements in his ability to communicate, handle transitions, calm down, and connect with others. He’s happier, more confident, and making progress we are so grateful for. Thank you to all the staff for everything! Highly recommend Neuroaffinity to any parent or caregiver.

Shehzad has been incredibly helpful throughout my ADHD journey. He was friendly, professional, and always took the time to listen and answer any questions I had. His support has made a real difference, and I felt understood and comfortable from the start. I would highly recommend Shehzad to anyone looking for ADHD support and assessment.

I was really happy with the professionalism shown by Neuroaffinity, specifically Shehzad. As parents we are always nervous and apprehensive but Shehzad put us at ease and took his time to answer all our questions, and dealt with our child remarkably well. Thank you!

I recently got my ADHD diagnosis and just at the end of my titration now. The team at Neuroaffinity has been fantastic, I was in somewhat of a rush as I had my a levels on this year and so I needed to have the diagnosis and initial titration appointment as soon as possible. They were great in facilitating this and beyond that in every area. Would certainly recommend their services!
