Can I Go Back to the NHS After a Private ADHD Assessment?
You may be able to use NHS services later, but a private diagnosis does not automatically guarantee NHS medication, shared care or faster access.
Some NHS GPs may consider shared care, while others may not. This can depend on local policy, the provider used and whether the assessment meets required standards.
Check before paying privately if you hope to transfer ongoing care to the NHS.
