NHS vs Private Assessment: What's the Difference?

10 April 2026

There are two main routes to getting an ADHD, autism, or dyslexia assessment in the UK: through the NHS or through a private provider.

NHS assessments are typically free at the point of access, but waiting times are often long due to high demand. In many areas, people may wait several months or longer for an appointment.

Private assessments involve paying for the service, but they usually offer significantly shorter waiting times. Many providers can offer appointments within weeks rather than months.

Private assessments may also provide more flexibility in scheduling and choice of clinician, including remote options.

For many people, the decision comes down to urgency, budget, and availability.
