Making mealtimes with an autistic child easier

For private assessments, we aim to arrange a pre-assessment with a Specialist Doctor within 72 hours. If a full autism assessment is recommended, all appointments are typically completed within 4 weeks. Some delays may occur for example if the educational placement is closed during the holiday period. A comprehensive report, including a diagnosis where appropriate, is usually delivered within 10 days of your final appointment.

If you are referred through your NHS Trust, timelines are similar, although this can vary depending on local demand.

No, you do not need a GP referral to access our private autism assessment service. Your first step is a consultation with one of our Specialist Doctors, all of whom also work within the NHS. They will discuss your child’s needs, development, and any concerns you or their school may have. If appropriate, you will be offered a short video consultation to review your child’s needs in more detail and decide whether to proceed with a full assessment.

The cost of a private autism assessment varies depending on the provider and the complexity of the assessment. To compare costs from other providers our costs cover the initial consultation, full diagnostic assessment, and a detailed written report. Mostly, you will be charged over £2,000 with some private clinics charging up to £3,500. We work hard to deliver our assessments at a lower rate than most of the market without compromising on quality. For example, some providers will assess your child without meeting them face-to-face. We believe that for an assessment to be thorough, we have to see your child in person.

Although our clinicians do carry out ADHD assessments in their NHS practice, we do not currently offer ADHD assessments at Autism Clinic London. Our Autism Assessments do include a comprehensive report and will highlight if there are possible ADHD concerns, which can then be explored in future by your child’s local NHS trust or by another provider.

Private autism assessments are highly accurate when conducted by experienced clinicians using evidence-based diagnostic tools and NICE guidelines.

A screening is an initial check to see whether autism may be present, while a full assessment is a comprehensive diagnostic process that can lead to a formal diagnosis. If you are concerned that your child has signs of Autism, please contact us and we can arrange an initial assessment in the first instance.

Some parts of the assessment process, such as initial consultations and diagnostic interviews with parent or carer, can be carried out online. However, a full diagnostic assessment will require in-person observation. Other providers may offer fully virtual assessments but such assessments do not meet our standards.

An autism diagnosis helps individuals and families understand their experiences, access appropriate support, and make informed decisions about education, healthcare, and daily life.

A diagnosis doesn’t change who your child is, but it can open doors to support, reduce uncertainty, and provide clarity for families and professionals. Once you have a confirmed diagnosis, you can also access appropriate and targeted post-diagnostic care, which can help day-to-day life enormously.

Yes, a diagnosis can help schools better understand your child’s needs and provide appropriate support, accommodations, and learning strategies. It can help inform an EHCP and a more complete approach to your child's educational needs.
