The ADI-R cost in the UK as part of a full private autism assessment typically ranges from £650 to £2,500, depending on the provider and what’s included. This structured interview is essential for gathering developmental history, and clinics often bundle it with other assessment stages.

What Influences the ADI-R Cost?

Costs vary due to several factors, including the clinic’s approach, location, and what’s included in the assessment package:

Evaluation Pricing

At practices like Berkshire Autism Service, the ADI-R phase alone costs £650, forming part of a larger assessment package that totals around £2,000. Other providers may charge more or less depending on service scope.

Clinical Fees

Private autism evaluations often include multiple components and typically range from £1,500 to £3,000 for a complete assessment.

Autism Interview Charges

Some clinics blend the ADI-R with a feedback session and report within a comprehensive package. The Priory, for example, starts full adult assessments from around £2,150, which include both ADI-R and ADOS‑2 stages.

What You’re Paying For

Here are the main elements typically included in the ADI‑R cost:

A one- to two-hour structured interview conducted with someone knowledgeable about early development.

Responses are scored and interpreted by trained clinicians.

Written summary with findings and recommendations.

Some larger packages also include ADOS‑2 observation, multidisciplinary team review, and post-diagnostic support.

In summary, the ADI‑R cost in a private UK assessment generally falls between £650 (interview-only phase) and £2,500 (full evaluation package), with most complete adult or child assessments priced around £1,800–£2,200.
