What are Autism Spectrum Disorders (ASD)?
Autism spectrum disorder assessment is essential for individuals experiencing challenges with social interactions, communication, and behaviour. Autism spectrum disorders include conditions such as Autistic Disorder, Asperger’s Syndrome, and Pervasive Developmental Disorder (NOS). Early private autism evaluation can provide clarity and access to appropriate interventions.
What is Asperger's Syndrome?
Asperger’s Syndrome is a form of high-functioning autism that affects social interactions and communication. Individuals with Asperger’s may exhibit high intelligence, strong subject interests, and strict routines. Our private autism assessment cost includes thorough Asperger’s testing to provide a precise diagnosis and support plan.

Challenges in understanding others' thoughts and emotions
Strong preference for routine and distress when it's disrupted

Our ASD Services in London
We offer a comprehensive ASD service, providing thorough assessment and expert management for all autism spectrum disorders. Our service is designed to support adults, delivered by experienced psychiatrists and psychologists with extensive expertise in autism care.
The process begins with an initial assessment by our medical specialists, incorporating a gold-standard diagnostic interview to evaluate how ASD affects daily life.
To confirm the diagnosis, we use a series of online questionnaires, completed by you or a friend. This allows us to collect objective, reliable data to establish a baseline and measure ASD symptoms accurately. If ASD is diagnosed, this data becomes a valuable tool in monitoring progress, assessing treatment effectiveness, and making adjustments when necessary.
We understand that an ASD diagnosis can be a significant moment for you and your family. Our consultant psychiatrists and paediatricians will guide you through the next steps, offering tailored support and management strategies to help navigate the future with confidence.
How We Diagnose Autism
We understand that medical assessments can feel overwhelming, but there’s no need to worry—our autism assessment is a straightforward and supportive process. No health or blood tests are required. Instead, our specialists focus on observing how you interact socially and communicate with others. We also explore your childhood development and any mental health challenges you may have experienced.
To ensure a thorough and accurate diagnosis, we use a range of validated diagnostic tools, including:
- Autism Diagnostic Observation Schedule (ADOS) – for children
- School Report – for children
- Autism Diagnostic Interview-Revised (ADI-R) & Client Questionnaire
- AQ-10 – Autism Spectrum Quotient screening tool
- AQ-50 – Self-assessment questionnaire measuring autism-related traits
- EQ-40 – Empathy Quotient self-report measure
- RAADS-R – Ritvo Autism Asperger Diagnostic Scale – Revised
- Relative Questionnaire – gathering insights from close family members
- GAD-7 – Generalised Anxiety Disorder assessment (7-item scale)
- PHQ-9 – Patient Health Questionnaire (9-item scale for depression severity and treatment response)
Following the assessment, your results will be carefully evaluated against the diagnostic criteria outlined in the International Classification of Diseases (ICD-10) and the National Institute for Health and Care Excellence (NICE) guidelines. These internationally recognised frameworks, including the DSM-IV criteria, ensure a precise and reliable diagnosis of ASD and Asperger’s syndrome.
