by RIDDOR Reporting in the UK: A Practical Guide to Incident Compliance
13 Oct, 2026You’ve just witnessed a slip-and-fall in your warehouse. The employee is shaken but seems okay. Do you stop work? Call an ambulance? Or just fill out an internal form and move on? If you’re running a business in the UK, that last option might land you with a hefty fine. RIDDOR (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013) isn’t just bureaucratic red tape; it’s the legal framework that keeps workplace safety data accurate across the country. Ignoring it doesn’t make the problem go away-it just makes you vulnerable during an inspection or a lawsuit.
What Exactly Is RIDDOR?
Think of RIDDOR as the mandatory diary for workplace safety. It requires employers, self-employed people, and those in control of premises (like landlords) to report specific incidents to the Health and Safety Executive (HSE). The goal isn’t to punish you for accidents happening; it’s to identify trends. If three factories in the same region report similar chemical leaks, the HSE can investigate systemic issues rather than individual blunders.
The regulations cover three main categories: injuries, diseases, and dangerous occurrences. You don’t report every bruise or minor cut. There are thresholds. For instance, if an injury prevents an employee from working their normal duties for more than seven consecutive days, it becomes reportable. This distinction saves businesses from drowning in paperwork while ensuring serious risks are tracked.
When Must You Report? The Critical Triggers
Timing is everything. Miss the deadline, and you’re non-compliant, even if you eventually file the report. Here is how the clock works for different scenarios:
- Fatalities and Major Injuries: These must be reported without delay. Ideally, call the HSE immediately after the incident occurs. If you can’t reach them by phone, submit the online report as soon as possible.
- Over-Seven-Day Injuries: You have 15 days from the date of the accident to report this. Note that the "seven days" refers to calendar days, not working days, excluding the day of the accident itself.
- Occupational Diseases: Once a registered medical practitioner provides a diagnosis, you have 15 days to report. Common examples include carpal tunnel syndrome, tendonitis, or hand-arm vibration syndrome.
- Dangerous Occurrences: These are near-misses or events that could have caused harm, like a crane collapse or a gas leak. Report these without delay.
What counts as a major injury? It’s not subjective. It includes fractures (other than fingers, thumbs, and toes), amputations, loss of sight due to chemical burns, or any injury leading to unconsciousness caused by head trauma. If your worker breaks a wrist, that’s a fracture. That’s reportable.
How to File Your RIDDOR Report
Gone are the days of mailing paper forms. Today, almost all reports go through the HSE Online System. It’s straightforward, but preparation is key. Before you log in, gather the following details:
- Employer Details: Your company name, address, and industry code.
- Injured Person’s Info: Name, age, gender, and job title. You don’t need their home address for public records, but you need it for your internal file.
- Incident Details: Date, time, location within the site, and a clear description of what happened. Avoid jargon. Write as if explaining it to someone who wasn’t there.
- Outcome: What was the injury? Was hospital treatment required? How many days off work resulted?
If you prefer speaking to a human, you can call the Incident Contact Centre. However, keep a note of the reference number they give you. Without that, proving you reported on time becomes a nightmare during an audit.
Common Pitfalls and Misconceptions
Many managers assume that if an accident happens outside working hours, it’s exempt. Wrong. If the activity was work-related-say, a team-building exercise or a client dinner where alcohol was served-you likely still have reporting obligations. Another common error is confusing first aid cases with reportable injuries. Applying a plaster isn’t reportable. Stitches might be, depending on severity and recovery time.
| Scenario | Reportable? | Reason |
|---|---|---|
| Employee slips on wet floor, sprains ankle, takes 3 days off | No | Under 7-day threshold |
| Employee falls from ladder, breaks arm | Yes | Major injury (fracture) |
| Contractor develops dermatitis from cleaning chemicals | Yes | Occupational disease diagnosed by doctor |
| Near miss: Heavy object falls but hits nobody | Maybe | Only if classified as a 'dangerous occurrence' under Reg 4 |
Who Is Responsible?
It’s rarely just one person. While the employer bears the ultimate responsibility, the duty extends to anyone controlling the premises. Imagine a scenario where a contractor injures themselves in your office because of a faulty cable managed by your facilities team. Who reports? Usually, the employer of the injured person reports the injury, but the party responsible for the hazard might also need to report a dangerous occurrence. Coordination between contractors and clients is vital to avoid double-reporting or, worse, no reporting at all.
Self-employed individuals have a narrower scope. They generally only report injuries to themselves that arise from their work activities and prevent them from doing their usual work for more than seven days. They do not report injuries to others unless those others are employees under their management.
Consequences of Non-Compliance
Why bother getting it right? Because the HSE has teeth. Failing to report a reportable incident is a criminal offense. Prosecution can lead to unlimited fines in the Crown Court. Beyond financial penalties, unreported incidents skew safety statistics. If your company appears safer on paper than it actually is, you might face unexpected scrutiny when inspectors arrive. Conversely, transparent reporting shows regulators you take safety seriously, which can sometimes mitigate enforcement actions.
Also, consider insurance implications. Insurers often require proof that statutory notifications were made. If you skip the RIDDOR step, you might find yourself arguing over coverage for a claim related to that very incident.
Beyond the Form: Building a Safety Culture
Reporting shouldn’t feel like a punishment. Use it as a tool. When you file a RIDDOR report, you’re forced to analyze why the incident happened. Was it training? Equipment failure? Fatigue? Documenting these root causes helps prevent recurrence. Keep a simple log of all incidents, even those below the reporting threshold. Patterns emerge quickly. Five minor trips in a month might signal a lighting issue that needs fixing before someone breaks a bone.
Do I need to report accidents involving visitors or customers?
Yes, but only if they are taken directly from the scene of the accident to a hospital for treatment of an injury arising out of or in connection with work. If a customer slips in your lobby and goes home, then visits a GP later, it’s usually not reportable unless the injury is severe enough to warrant immediate hospital transfer.
What happens if I miss the 15-day deadline?
You should still report it. Late reporting is better than no reporting. However, you may face enforcement action for failing to comply with the regulation. The HSE inspector will look at why the delay occurred. If it was an administrative error, they might accept it with a warning, but repeated offenses lead to fines.
Are mental health issues covered under RIDDOR?
Generally, no. Stress, anxiety, or depression are not currently listed as reportable occupational diseases under RIDDOR 2013, unless they result from a physical injury or accident. However, always check for updates, as health and safety laws evolve to reflect modern workplace realities.
Can I delete a RIDDOR report if the injury turns out to be minor?
No, you cannot simply delete it. If you realize you reported an incident that didn’t meet the criteria (e.g., the employee returned to work within 6 days instead of 7+), you should contact the HSE to inform them of the correction. Transparency is key; hiding errors looks worse than admitting them.
Does RIDDOR apply to remote workers?
Yes. If a remote worker suffers an injury while performing work tasks at home (e.g., tripping over a laptop charger during a video call setup), and it meets the reporting criteria, it is reportable. The location doesn’t negate the work-related nature of the incident.
