RIDDOR: what to report and when
RIDDOR is the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013. Employers, the self-employed and people in control of work premises must report certain work-related accidents to the HSE. Most reports are made online on the HSE website.
What must be reported
| Event | Deadline |
|---|---|
| Death of a worker or a member of the public caused by a work accident | Without delay; report within 10 days |
| Specified injury to a worker (for example a fracture other than to fingers, thumbs or toes, an amputation, serious burns, loss of consciousness from a head injury) | Without delay; report within 10 days |
| Worker unable to do their normal work for more than 7 consecutive days (not counting the day of the accident) | Within 15 days of the accident |
| Member of the public taken from the scene straight to hospital for treatment | Within 10 days |
| Diagnosed occupational disease (for example carpal tunnel syndrome, occupational dermatitis, occupational asthma) | When you receive the written diagnosis |
| Dangerous occurrence (a listed near miss, for example collapse of scaffolding or a lifting equipment failure) | Within 10 days |
Fatal and specified injuries can also be reported by telephone to the HSE incident contact centre.
Over-3-day injuries
If a worker is off or on light duties for more than three consecutive days, you do not report it, but you must record it. An accident book entry counts as that record.
What is not reportable
- Accidents that are not work-related, for example a customer who trips over their own shoelace with nothing wrong in the premises.
- A member of the public taken to hospital only for checks, or as a precaution, with no treatment.
- Most road traffic accidents on public roads.
Records
Keep a record of every reportable incident, and of over-3-day injuries, for at least three years: date and method of reporting, date, time and place, personal details of those involved and a brief description. Businesses with 10 or more employees must also keep an accident book under social security law.
Record the accident and check RIDDOR in one go. The free online accident book asks the key questions, tells you whether the incident looks reportable and gives you a PDF record. Pro stores all records with your other fire and COSHH paperwork.

Who reports under RIDDOR?
The “responsible person”: the employer for employees, the self-employed person for themselves, or the person in control of the premises for members of the public and some self-employed workers.
Is a near miss reportable?
Only if it is one of the dangerous occurrences listed in Schedule 2 of RIDDOR. Other near misses are worth recording internally but are not reported.
Does RIDDOR apply in Northern Ireland?
Northern Ireland has its own RIDDOR regulations (1997), reported to HSENI. The 2013 regulations cover Great Britain.
