How to Report under RIDDOR: the Form, the Deadline, the HSE
The RIDDOR report is a procedure, and the procedure is what makes the report right the first time: find the reportable, use the form, beat the deadline, and run the internal procedure that catches the reportable before the deadline. This guide is the reporting procedure in working form.

The step: find the reportable, then report
The first step is the check, not the form. When an incident happens on site, the question is: does it sit on one of the five RIDDOR lines — the death, the specified injury, the over-7-day injury, the notifiable disease, the dangerous occurrence? If yes, it is reportable, and the clock is running.
The report comes second. The internal record happens the same day, the first-aid response happens immediately, and the RIDDOR report goes to the HSE inside the deadline. Report first, investigate second — the investigation runs in parallel; it does not gate the report.
The form: the online route, and what to include
The report goes to the HSE three ways: online (the HSE website, the typical route, about 10 minutes), by phone (the 24-hour line, for the immediate reports — the death and the specified injury), or by post. The phone report is followed up with the online form.
The form captures four blocks: the reporter (name, contact, role), the person injured (name, occupation), the incident (date, time, location, description), and the details (the injury, the part of the body, the cause). A supervisor who knows the site can complete the form in one sitting — which is the point of the internal procedure.
The deadline: the clock runs from the incident
The RIDDOR clock runs from the date of the incident — not from the investigation, not from the end of the week. The death, the specified injury, and the serious dangerous occurrences are reported immediately, as soon as practicable. The over-7-day injury, the notifiable disease, and the other occurrences are reported within 15 days.
The deadline is not optional: a late report is an offence, and the offence is what the prosecution is built on. The procedure that misses the deadline is the procedure that fails — whatever else the site did well.
The internal procedure: the supervisor knows
The internal procedure runs the incident to the report: the incident (record it, first aid, the same shift), the reportable check (the five lines, a yes or no), the deadline (the clock, from the incident), and the report (online or phone, to the HSE).
The supervisor owns the procedure, and the supervisor is briefed on it in the toolbox talk. A procedure that is not reviewed is a procedure that does not work — the review is annual, and after every near-miss that was close. The internal report is the duty in Section 7 of the HSWA, and it is what feeds the RIDDOR.

RIDDOR Reporting Timescales (the Deadlines at a Glance)
The deadlines, at a glance: the death — 15 days; the dangerous occurrence — 15 days; the specified injury — 15 days; the over-7-day incapacitation — 7 days; the notifiable disease — 14 days. The report goes to the HSE on the RIDDOR online form, and the phone line is for the urgent. The internal procedure runs ahead of the deadline — the event is reported to the supervisor the same shift, the first facts are recorded while they are fresh, and the responsible person decides the reportable and the deadline, on the day, not at the end of the week.
Who Is Responsible for RIDDOR Reporting?
The duty to report sits with the responsible person — the employer, the self-employed, or the one who controls the premises (the school, the hospital, the prison, the construction site where there is no employer). The worker reports to the supervisor, the supervisor to the responsible person, and the responsible person to the HSE. The chain is the procedure, and the procedure that fails is the one where the worker is told to "not make a fuss" — the internal report is the duty in Section 7 of the HSWA, and it is the one that feeds the RIDDOR.
Need the sign-off, not just the guide?
The guide is the preparation; the sign-off is the professional. For the ISO 45001 implementation and audits, the RIDDOR and CDM work, the statutory assessments and the training that comes with them, ask Muhammad Umer — 8+ years across Iraq, KSA and Pakistan, and the programme runs through umer-hse.pro. One message gets the written scope.
Common questions
How to Report under RIDDOR — answered
How do you report an incident under RIDDOR?
To the HSE: online (the HSE website, the typical route, about 10 minutes), by phone (the 24-hour line, for the immediate reports — the death and the specified injury), or by post. The report captures the reporter, the person injured, the incident (date, time, location, description), and the details (the injury, the cause).
What is the RIDDOR reporting form?
The online form on the HSE website: the reporter, the person injured (name, occupation), the incident (date, time, location, description), and the details (the injury, the part of the body, the cause). A supervisor who knows the site can complete it in about 10 minutes. The phone report is followed up with the online form.
What are the RIDDOR reporting time limits?
The death and the specified injury: immediately, as soon as practicable. The over-7-day injury, the notifiable disease, and the dangerous occurrence: within 15 days of the incident. The clock runs from the date of the incident, not from the investigation.
Who is responsible for RIDDOR reporting?
The responsible person: the employer, the self-employed, or the one who controls the premises where there is no employer. The worker reports to the supervisor, the supervisor to the responsible person, and the responsible person to the HSE.
What happens if you do not report under RIDDOR?
Failing to report is an offence, and the penalty is a fine — unlimited on summary conviction. The fine can reach the company and the responsible person. A late report typically starts with an HSE letter, and the letter can become an improvement notice.
What is the difference between RIDDOR and an incident report?
The scope. The incident report is the internal document: what happened, why, the actions, the owner. The RIDDOR is the report to the HSE: the reportable incident, the facts, the deadline. Every RIDDOR incident has an incident report; not every incident report becomes a RIDDOR.
