INDEPENDENT GUIDANCE — not project-specific legal/design advice or a compliance certificate. Check the official current requirements and applicable transition.

RIDDOR requires specified work-related injuries, diseases and dangerous occurrences to be reported by the responsible person. Not every accident or near miss is reportable, but an event need not cause injury to fall within a dangerous-occurrence category. Reporting does not replace emergency response or investigation.

WHAT TO CHECK
[ ] Protect people and arrange emergency assistance before dealing with reporting administration.
[ ] Identify the responsible reporter and gather reliable facts on the event and work connection.
[ ] Compare facts with the correct reportable category, including specified dangerous occurrences and non-worker cases.
[ ] Check the category-specific reporting deadline and use the official reporting route without unnecessary delay.
[ ] Keep the required record, investigate causes and track preventive action separately from the submission.

RECORDS TO KEEP
- Incident facts, witnesses and relevant contemporaneous evidence handled appropriately.
- Reportability decision, submitted report and acknowledgement where applicable.
- Investigation findings, corrective actions and required accident records.

WHEN TO GET SPECIALIST HELP
Use current HSE category guidance promptly when reportability or the responsible person is unclear; seek competent safety advice without delaying an applicable statutory deadline.

SCOPE AND EDITION
Sources reviewed 17 October 2026. Applies in Great Britain, including England. Deadlines and records depend on the event; no single deadline in this entry should be substituted for category-specific current requirements.
