Is it RIDDOR reportable?
Tell us about the incident in plain English. In about 60 seconds we'll tell you whether you need to report it under RIDDOR, what the deadline is, and how to do it.
What happened?
Pick the option that fits best.
Who was injured?
How serious was the injury?
Pick the most serious outcome that applies.
Were they taken to hospital?
For RIDDOR, what matters is whether they went to hospital from the scene for treatment of an injury that arose from the work activity.
Which condition has been diagnosed?
RIDDOR's reportable disease list is short and specific. Pick the closest:
Which "dangerous occurrence"?
RIDDOR has a defined list of 28 dangerous occurrences. Pick the closest:
Yes — this needs to be reported.
Category: Death (RIDDOR Regulation 6)
Any death of a worker, contractor or member of the public arising out of, or in connection with, work is RIDDOR reportable.
- Notify HSE without delay — fatalities should be reported by telephone in the first instance.
- Written report deadline: within 10 days of the incident.
- Phone (fatalities): 0345 300 9923 (Mon–Fri 8.30am–5pm)
Yes — this needs to be reported.
Category: Specified injury to a worker (Regulation 4)
Specified injuries to workers are always RIDDOR reportable, regardless of how much time the worker subsequently takes off.
- Deadline: within 10 days of the incident.
- Who reports: the responsible person — usually the employer, or the person in control of the premises.
- Keep the records: RIDDOR records must be kept for at least 3 years.
Yes — this needs to be reported.
Category: Over-7-day injury to a worker (Regulation 4)
Where a worker is incapacitated for more than 7 consecutive days as a result of an occupational accident or injury, the incident is RIDDOR reportable.
- Deadline: within 15 days of the incident (longer than the 10 days for specified injuries).
- How "7 days" is counted: excludes the day of the incident, but includes weekends and rest days.
- You also need to record over-3-day injuries in the accident book — these don't get reported to HSE, but must be kept for 3 years.
Yes — this needs to be reported.
Category: Injury to a non-worker (Regulation 5)
Injuries to members of the public or others not at work are reportable when they're taken to hospital from the scene of the accident for treatment of an injury that arose out of, or in connection with, the work activity.
- Deadline: within 10 days of the incident.
- Examination only doesn't count: the hospital visit must be for treatment of the injury, not just precautionary check-up.
Yes — this needs to be reported.
Category: Occupational disease (Regulation 8)
The condition you've selected is on RIDDOR's reportable disease list, provided the worker's job exposed them to the relevant risk and a doctor has formally diagnosed it.
- Trigger: the diagnosis must be in writing from a registered medical practitioner.
- Deadline: as soon as possible after the diagnosis is received.
- Use the right form: there's a separate form for diseases on the HSE site.
Yes — this needs to be reported.
Category: Dangerous occurrence (Regulation 7)
The event you've described is on RIDDOR's list of 28 dangerous occurrences. Even if no-one was hurt, it's reportable because of the potential for harm.
- Deadline: within 10 days of the occurrence.
- Investigate it as well: the report is the legal minimum — a near-miss like this should always trigger a root-cause investigation.
This needs a closer look.
RIDDOR's list of dangerous occurrences is specific (28 categories) but covers a lot of ground. If you're not sure, the safe course is to check the HSE list directly — or call us and we'll help you decide.
- HSE list: the full list is in Schedule 2 of the regulations.
- When in doubt, report: non-reporting of a reportable event is an offence; over-reporting isn't.
Yes — gas incidents are usually reportable.
Category: Gas incident (Regulations 11 & 12)
Two things to check — (a) gas distribution incidents (death/injury/property damage arising from a flammable gas distribution incident) are reportable by gas conveyors; (b) Gas Safe registered installers must report any gas appliance defect that could cause death, loss of consciousness or admission to hospital.
- Deadline: within 14 days of becoming aware (gas appliance defects).
- Use the dedicated gas form on the HSE website.
No — but you still need to record it.
Minor injuries that don't meet the "specified injury" or "over-7-day" thresholds aren't reportable to HSE under RIDDOR — but they still need to be entered in your accident book.
- Over-3-day injury rule: if the worker is off normal duties for more than 3 days, you must keep a written record (kept for at least 3 years) — but no HSE report.
- Always investigate: minor incidents are early warning signs. A real near-miss culture catches these and stops them escalating.
- Watch for cumulative patterns: repeated minor injuries to one person, or in one area, may point to an underlying control failure.
No — but record and review.
Injuries to members of the public are only RIDDOR reportable when the person is taken from the scene to hospital for treatment. First aid, walk-away injuries, or hospital visits made later under the person's own steam don't trigger a RIDDOR report.
- Document it: first-aid log, witness statement, photo of location.
- Investigate: if the public was exposed to a hazard from your work, find out why and prevent recurrence.
- Check your insurer: public liability cover usually requires notification of any incident, not just RIDDOR ones.
No — but check the full HSE list before you close the case.
The conditions on this tool's shortlist cover most cases. If your scenario doesn't fit any of them, it's likely not RIDDOR reportable as a disease — but RIDDOR's full list includes a longer set of cancers and biological-agent diseases worth a quick look before you decide.
- Even if not reportable: work-related ill-health should still be investigated and controls reviewed.
- Talk to occupational health: a clinician's view will help you understand whether work caused or contributed to the condition.
This tool gives general guidance only. RIDDOR is layered, and edge cases exist. When in doubt, report — or call us on 01843 852277 and we'll talk it through with you.
RIDDOR in 90 seconds.
RIDDOR — the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 — is the legal framework that tells employers, the self-employed and people in control of work premises which work-related incidents need to be reported to the HSE.
Five things get reported: deaths, specified injuries to workers, over-7-day incapacities, injuries to non-workers taken to hospital from the scene, certain occupational diseases, and a defined list of dangerous occurrences. Gas incidents have their own pathway.
The "responsible person" — usually the employer, or the person in control of the premises — must report. Most reports go in within 10 days of the incident; over-7-day injuries get 15 days.
Failure to report is an offence under the Health and Safety at Work etc Act 1974. Penalties range from improvement notices to unlimited fines on summary conviction. The bigger risk, though, is reputational and operational — clients, insurers and HSE inspectors all use RIDDOR data as a signal of how seriously a business takes safety.
