The fee includes a full clinical diagnostic interview (60–90 minutes), a structured assessment following NICE guideline NG87, a comprehensive written diagnostic report issued within 5 working days, and a discussion of treatment options where clinically appropriate. There are no hidden fees.
Can I get a free ADHD assessment on the NHS?
Yes, NHS ADHD assessments are free. However, waiting times currently exceed 3–5 years in most parts of England. Under the NHS Right to Choose pathway, you can self-refer to a private provider for an NHS-funded assessment — meaning you get a private assessment at no cost to you, without waiting on the NHS list.
Does health insurance cover private ADHD assessments?
Some private health insurance policies cover ADHD assessments. Check your policy documents or contact your insurer directly. You will typically need to confirm that the provider is CQC-registered and that the clinician is GMC-registered. ADHD Assessment UK meets both requirements.
Are there payment plans available?
Yes. We offer interest-free payment options to spread the cost of your assessment. Contact us to discuss payment plan arrangements before booking.
Why is there such a wide range in private ADHD assessment costs?
The cost varies based on the type of clinician (psychiatrist vs specialist nurse), the length and depth of the assessment, whether a written report is included, and the overhead costs of the provider. Online-only questionnaire-based assessments are cheaper but may not meet the clinical standards required for a formal diagnosis. ADHD Assessment UK provides a full clinical assessment at a competitive price.
