Private Autism Assessment Cost UK 2026: Adult & Child
What a private autism assessment in the UK covers for adults and children, the NHS route, reports, school evidence and follow-up, and what to ask about the fee.
Quick answer: NHS autism assessment is free after referral, but waits vary widely by area. Private providers set their own fees. Before paying, compare clinician credentials, assessment length, what evidence is reviewed and whether a written report is included.
What a private autism assessment may involve
| Assessment type | Notes |
|---|---|
| Adult online assessment | Often psychiatrist or psychologist led |
| Adult in-person assessment | Location and clinician mix affect the fee |
| Child autism assessment | May involve multidisciplinary input |
| Additional school report or meeting | Sometimes charged separately |
| Follow-up appointment | Check whether it is included |
No price is given for these. We have not read enough providers' own autism assessment prices to publish one. Our mental health provider directory lists providers with the services their own pages describe and, where a fee could be tied to a named service, that fee with its source.
NHS vs private route
The NHS route is free and remains an important option, especially for children, where education and local authority support may be involved. Some people consider a private assessment where timing, work, education or family circumstances create a need for an earlier answer. Check whether your GP, school or employer will accept a private diagnosis before booking.

Frequently asked questions
How much does a private autism assessment cost in the UK?
Providers set their own fees, and an adult online assessment, an adult in-person assessment and a child multidisciplinary assessment are different services. We have not read enough providers' own autism assessment prices to publish a figure, so none is given here. Our mental health provider directory records what each provider's pages say about the services it offers.
Can I get an autism assessment on the NHS?
Yes. NHS assessment is free after referral, but waiting times vary widely by area and age group.
What should be included in the assessment?
Ask who assesses you, whether standardised tools are used, whether school or family evidence is reviewed, and whether a written diagnostic report is included.
