What can I do if an autism or ADHD referral is refused, or I disagree with an assessment outcome in the UK?
A refused referral, discharge after triage, no-diagnosis result, factual error and disagreement with a clinical conclusion are different problems and may have different review or complaint routes.
Current understanding
First ask the referrer or assessment service to explain what decision was made and why: a referral may have been declined, triage may have concluded that a full assessment is not indicated, or a completed assessment may have reached a no-diagnosis or different conclusion. Check whether missing or inaccurate factual information can be supplied or corrected and what the local review, re-referral, second-opinion or complaint route is. The NHS England autism page explicitly says that a person who disagrees with the result can ask the GP or assessment team about referral to another team for a second opinion; ND Oracle does not generalise that exact mechanism as a UK-wide entitlement. In Scotland, Wales and Northern Ireland the practical route must be checked with the relevant NHS board, health board/HSC Trust, GP or service. Disagreement alone does not establish that the assessment was wrong, and a service decision does not erase support needs that may still require attention.

What evidence is still needed
- Current nation- and service-level second-opinion, re-referral, records-correction and complaints routes for autism and ADHD assessments outside the explicit England NHS autism example.
Where people may disagree
- Clinical disagreement can reflect new evidence, a flawed process, genuinely uncertain presentation or a defensible difference in professional judgement; ND Oracle should preserve those possibilities rather than declaring either side correct.
When this answer should be revisited
- National health services publish materially different second-opinion or neurodevelopmental review rules.
- Local service review/complaint arrangements materially change.

Cross-UK route assembled from current public assessment guidance. England's explicit NHS second-opinion wording is kept England-specific; elsewhere the route directs readers to the relevant service/GP/Trust/board process rather than inventing a uniform right.
