Private London ASD assessments for children, teens and adults.
Autism Spectrum Disorder (ASD) is a neurodevelopmental condition that affects communication, behaviour and social interaction. Because autism presents differently in each person, a clear and accurate diagnosis is essential.
Our specialist ASD assessments offer the clarity, understanding and guidance needed at any age.
ASD assessments for children
Parents may notice early signs such as reduced eye contact, delayed language, sensory sensitivities or repetitive behaviours. Early assessment helps families understand their child’s needs and access support as soon as possible.
ASD assessments for adults
Many adults seek a private autism assessment after recognising long-standing traits or challenges. A diagnosis can offer relief, validation and access to tailored support.
Whether you are a parent seeking answers for your child or an adult exploring assessment for yourself, our team provides compassionate and professional guidance throughout the process.
What are the signs of autism?
Autism characteristics vary widely, but common signs include:
-
Difficulties with social communication or understanding social cues
-
Repetitive behaviours or highly focused interests
-
Sensory sensitivities (e.g., sound, textures, lights)
-
Challenges adapting to change
-
Delayed or atypical language development
If these signs feel familiar, a structured autism evaluation in London can provide clarity and direction.
What happens during a private autism assessment?
A private ASD assessment does not rely on a single test. Instead, our team uses a combination of internationally recognised tools, interviews and clinical observations to provide an accurate diagnosis.
Our multidisciplinary approach includes consultant psychiatrists, psychologists and therapists who work together to understand the individual's developmental history, behaviour and needs.
Private autism assessments for children
Our child ASD assessments help parents identify developmental differences and understand their child’s strengths and support needs.
Assessments typically include:
-
Initial parental consultation: Reviewing developmental history and key concerns.
-
Observations and play-based assessments: For younger children, interactive tools help assess communication, behaviour and social interaction.
-
Standardised testing: Tools such as the Autism Diagnostic Observation Schedule (ADOS-2) provide detailed clinical insight.
-
Feedback session & report: Clear recommendations for therapies, school support and next steps.
Private autism assessments for adults
Adults receive a structured, evidence-based assessment that includes:
-
In-depth diagnostic interview: Exploring childhood development, social communication, behavioural patterns and daily challenges.
-
Standardised diagnostic tools: Such as the Autism Diagnostic Interview–Revised (ADI-R).
-
Comorbidity screening: Considering co-existing conditions like ADHD, anxiety or depression for a full clinical picture.
-
Comprehensive written report: Detailing findings, recommendations and tailored strategies for ongoing support.
