1. Who was affected?
Indicative guidance only — not a legal determination. Nothing you enter is stored.
What has to be reported under RIDDOR?
In broad terms: work-related deaths; "specified injuries" to workers (such as fractures other than to fingers/thumbs/toes, amputations, serious burns or loss of consciousness); injuries that stop a worker doing their normal job for more than seven days; injuries to members of the public that take them to hospital for treatment; certain diagnosed occupational diseases; a list of "dangerous occurrences" (serious near-misses); and gas incidents. Minor injuries aren't reported, but you should still record them.
Reporting timescales
Deaths, specified injuries and dangerous occurrences must be reported without delay (a phone report is accepted for the most serious), with the written report following within 10 days. Over-7-day injuries have up to 15 days from the accident. Getting the timescale right matters as much as reporting at all.
Keep incidents logged and ready
The businesses that handle RIDDOR well are the ones already logging every accident, incident and near-miss — so when something serious happens, the record and the decision are quick. Complys keeps that log and the evidence behind it, and you can gauge your wider position with the workplace H&S checker.
RIDDOR — FAQs
What is RIDDOR?
RIDDOR is the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013. It requires employers, the self-employed and people in control of premises to report certain serious workplace incidents to the HSE — deaths, specified injuries, over-7-day injuries to workers, injuries to members of the public taken to hospital, certain occupational diseases, listed dangerous occurrences and gas incidents.
What's the difference between an over-3-day and an over-7-day injury?
If a worker is incapacitated (can't do their normal duties) for more than 3 consecutive days, you must record it. It only becomes reportable to the HSE if the incapacitation lasts more than 7 consecutive days, not counting the day of the accident — reportable within 15 days.
How do I report a RIDDOR incident?
Most reports are made online using the HSE's RIDDOR form (F2508). Deaths and specified injuries can also be reported by phone to the HSE without delay. This checker points you to the right route for your situation.
Is this an official HSE tool?
No. It's an independent Complys tool that gives indicative guidance to help you decide — it isn't a legal determination and isn't affiliated with the HSE. If you're in any doubt, follow the official HSE RIDDOR guidance or take advice.
