See Clinicians for this Assessment

An in-person autism assessment for children and young people aged 6–17, including a detailed multidisciplinary (MDT) diagnostic report, held at our clinic in central London.

If you are seeking clarity or a formal autism diagnosis for your child, our in-person assessments provide a structured, child-centred way to understand what is going on and plan the right support. Being in the room with a clinician can feel more natural for some children and families, especially where anxiety, communication differences or sensory needs make online-only appointments more challenging.

We offer weekday and Saturday appointments, which can make it easier to attend without your child needing to miss school.

This is a two-part multi disciplinary assessment that combines:

  • A 60-minute in-person ADOS-2 session at our clinic with you and your child, led by Neurodiversity Specialist including child and adolescent services within NHS.
  • A separate 30-minute online ADI-R–informed developmental interview with the parent/carer only, led by our Chartered Psychologist.

Using more than one clinician and combining direct observation (ADOS-2), parent/carer interview (ADI-R framework) and questionnaires reflects best practice NICE compliant pathways for autism assessments and accepted by the NHS. The assessment also involves feedback from the child’s school.

Your child’s assessment report can be used to support an application for EHCP (Education Healthcare Plan).

To schedule your child’s in-person Autism assessment, please select a suitable date and time, then follow the instructions to complete your payment. Flexible payment options (including Klarna) are available.

Please Note: We do not accept insurance payments for this type of appointment.

Why book an In-Person Child Autism Assessment?

Parents come to us for an in-person autism assessment when they:

  • Want a clear, formal autism diagnosis (or to rule autism out) for their child or teenager
  • Prefer their child to meet a clinician in-person in a calm, structured clinic setting
  • Need appointments that fit around school and work commitments, including Saturday clinics
  • Have noticed differences in social interaction, communication, play, flexibility, sensory responses or routines and want to understand why
  • Feel that school or other services recognise difficulties, but there is still no clear explanation or plan
  • Are on a long NHS waiting list and need timelier answers and recommendations
  • Need a detailed report that can be used to inform school support, EHCP applications, or other services
A focused MDT assessment helps you and your child:
  • Put long-standing difficulties into context
  • Understand whether your child meets criteria for autism, and how this relates to their day-to-day life
  • Identify any co-existing difficulties (for example anxiety, low mood or ADHD traits) that also need attention
  • Agree evidence-based treatment options that feel realistic for your family
  • Have more confident conversations with school, your GP and other professionals
