In England, you can seek an autism assessment through the NHS or through a private clinic. Both routes lead to a clinically valid diagnosis — but there are important practical differences families should know.
NHS pathway
- Referral via GP required
- Current wait: 1–5 years in most areas
- No cost to the family
- Post-diagnosis support available
Private clinic
- No GP referral required
- Faster access
- Appointments typically within days
- Cost: £1,200–£2,500+ (varies)
- Specialist psychologist-led
- Full report issued; accepted by schools & EHCP
Many families come to us after years on an NHS waiting list, particularly when their child is struggling at school and needs support now, not in three years. A private assessment report carries exactly the same clinical weight as an NHS diagnosis and is recognised by local authorities for Education, Health and Care Plans (EHCPs).
