RIDDOR: The Guide for UK Workplaces

RIDDOR stands for the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations. It’s a set of UK health and safety laws that require employers, the self-employed, and those in control of work premises to report and record certain serious workplace incidents. This includes specific injuries, diagnosed occupational diseases, dangerous occurrences and work related deaths.

RIDDOR isn’t just red tape. It’s about identifying risks, learning from mistakes, and creating safer workplaces for everyone. If you’re running a business, managing a site, or even just working on the tools, understanding RIDDOR is essential.

Why is RIDDOR Important?

Failing to comply with RIDDOR can land you in serious trouble. We’re talking fines, legal action, and even prison in extreme cases. But it’s not just about avoiding penalties. RIDDOR:

Helps identify workplace risks and trends.
Triggers investigations that can prevent future accidents.
Demonstrates your commitment to health and safety (which is good for morale, reputation, and the bottom line).
Keeps you compliant with UK law. No one wants the HSE knocking on the door.

Who Needs to Report Under RIDDOR?

Not everyone needs to file a report. Just the “responsible person” does. That’s usually:

Employers (for their workers)
Self-employed people (for themselves)
People in control of work premises (like site managers or landlords)

Employees and the public don’t report directly under RIDDOR, but if you witness something dodgy, you should absolutely tell the person in charge!

What Incidents Must Be Reported Under RIDDOR?

Not every scraped knee or paper cut makes the cut. RIDDOR focuses on the big stuff, incidents that are serious, work-related, and meet specific criteria. Here’s what you need to know:

1. Work-Related Deaths

Any fatality caused by a workplace accident (including non-workers, like visitors or customers).

2. Specified Injuries to Workers

These include:

Fractures (except fingers, thumbs, toes)
Amputations
Loss of sight (temporary or permanent)
Serious burns (covering more than 10% of the body, or damaging eyes, respiratory system, or vital organs)
Scalpings (where the skin is separated from the head)
Loss of consciousness caused by head injury or asphyxia
Crush injuries to the head or torso, causing internal organ damage
Injuries from working in confined spaces.

3. Over-Seven-Day Injuries

If a worker is unable to perform their normal duties for more than seven consecutive days after an accident, it’s reportable. (Don’t count the day of the accident, but do include weekends and rest days).

4. Occupational Diseases

Diagnosed by a doctor and caused by work activities, such as:

Carpal tunnel syndrome
Severe cramp of the hand or forearm
Occupational dermatitis
Hand-arm vibration syndrome
Occupational asthma
Tendonitis or tenosynovitis
Certain cancers and biological agent exposures.

5. Dangerous Occurrences

These are “near-miss” events with the potential to cause serious harm, such as:

Collapse of scaffolding or lifting equipment
Explosions or fires
Uncontrolled release of substances (like chemicals or gas)
Electrical short circuits causing fire or explosion
Structural collapses.

6. Injuries to Non-Workers

If a member of the public is injured on your premises and taken directly to hospital for treatment, you must report it.

What Doesn’t Need to Be Reported?

Minor injuries (cuts, bruises, sprains).
Absences of less than seven days (unless it’s a specified injury).
Incidents that aren’t work-related.
Gradual injuries with no specific incident (unless diagnosed as an occupational disease).

How to Make a RIDDOR Report

Step 1: Identify the Incident

Is it work-related?
Does it meet the criteria above?
Are you the “responsible person”?

Before making a RIDDOR report, you must confirm that the incident occurred as a result of work activities, fits one of the specific categories outlined by RIDDOR (such as a specified injury, occupational disease, dangerous occurrence, or fatality), and that you are the designated “responsible person” (typically the employer, self-employed, or person in control of the premises) legally required to report.

Step 2: Report Promptly

Fatalities and specified injuries: Report without delay (ideally within 10 days).
Over-seven-day injuries: Report within 15 days.
Occupational diseases: Report as soon as you receive a diagnosis.
Dangerous occurrences and gas incidents: Report immediately.

Timely reporting is crucial. Fatalities and major injuries should be reported as soon as possible, ideally within 10 days, while over-seven-day injuries must be reported within 15 days, and occupational diseases as soon as they are diagnosed; dangerous occurrences and gas incidents require immediate notification to ensure compliance and enable swift action by the authorities.

Step 3: Use the Right Channel

Online: Most incidents are reported via the HSE’s RIDDOR portal.
Phone: Only for fatalities and major injuries (see HSE for the current number).

Step 4: Keep Records

You must keep records of all reportable incidents for at least three years (but five to six years is safer for insurance and legal claims). Records can be digital or paper, but they must include:

Date and time of incident
Details of those involved
Description of the incident and injuries
Place where it happened
What action was taken

It’s a legal requirement to maintain organised records of all reportable incidents for at least three years (though keeping them for five to six years is best practice), ensuring you include all relevant details, such as dates, those involved and a factual account, which supports compliance, future investigations, and potential insurance claims.

RIDDOR in Practice: Real-World Examples

Here’s how RIDDOR works in the wild:

Example	Is it Reportable?	Why?
Warehouse worker breaks arm falling from ladder	Yes	Specified injury (fracture)
Office worker off for 10 days after slipping	Yes	Over-seven-day injury
Customer taken to A&E after tripping in shop	Yes	Injury to a non-worker taken to hospital
Engineer finds faulty gas boiler leading to confirmed CO poisoning	Yes	Dangerous gas incident – Reportable to Gas Safe, not the HSE
Worker diagnosed with hand-arm vibration syndrome	Yes	Occupational disease
Forklift bumps into racking, no injuries	No	Not reportable unless it’s a dangerous occurrence (e.g. collapse)

RIDDOR for Construction Workers, Plumbers, Gas Engineers, and Electricians

RIDDOR is especially critical for those working in construction and building services, where the risks are high and the consequences of non-compliance can be severe. Data from the Health and Safety Executive revealed the scale of the challenge: a staggering 47,000 people working in construction trades suffered a non-fatal injury at work between 2021/22 and 2023/24. Even more sobering, the construction industry experienced nearly one fatality every week, with 51 fatal injuries recorded in 2023/24 alone. These figures highlight just how important it is for everyone in the sector, whether you’re on the tools or managing a site, to understand and meet your RIDDOR obligations.

Construction Workers

Construction sites are high-risk environments, so RIDDOR reporting is especially important. All deaths and serious injuries on site, such as fractures (excluding fingers, thumbs, and toes), amputations, permanent loss of sight, crush injuries to the head or body, serious burns, scalping requiring hospital treatment, and loss of consciousness due to head injury or asphyxia, must be reported. Over-seven-day injuries, where a worker cannot perform their normal duties for more than seven consecutive days, are also reportable. Dangerous occurrences, like scaffold collapses, electrical incidents, or the unintentional release of hazardous substances, must be reported immediately to help prevent future accidents.

Plumbers

For plumbers, RIDDOR reporting often centres around work-related injuries and dangerous occurrences involving water or heating systems. If you or a colleague suffer a serious injury (such as a fracture, amputation, or burn) while working, or if there’s a dangerous occurrence, like an unvented water cylinder explosion or major water leak that could have caused harm, it must be reported. Over-seven-day absences due to injury are also notifiable. Additionally, if you come across gas-related incidents while working on heating systems, you may have a duty to report under RIDDOR, especially if you’re Gas Safe registered.

Gas Engineers

Gas engineers have specific and critical obligations under RIDDOR. You must report any work-related accident that causes death or a specified injury, but you’re also legally required to report dangerous gas fittings or appliances. IGEM produced the Gas Industry Unsafe Situations Procedure (GIUSP) to bring consistency and reliability to how gas engineers deal with unsafe situations and the reporting of RIDDOR.

Situations where a gas appliance or installation are found to be so dangerous, i.e. that it could result in death, loss of consciousness, or require hospital treatment, such as accidental gas leaks, incomplete combustion, or inadequate removal of combustion products, would result in a report to Gas Safe. If there had been an explosion or exposure to CO confirmed in a medical environment, then a RIDDOR report would need to be made to the HSE. There is a subtle difference in that if there is a potential risk, Gas Safe would need to be informed, whereas if there is an actual incident, HSE would need to be informed via a RIDDOR report.

Keeping detailed records of all reportable incidents, including gas-related near misses, is essential for ensuring compliance and maintaining public safety.

Electricians

Electricians face unique risks, particularly from electrical shocks, burns, and fires. Any incident where an electrician (or anyone else) suffers a reportable injury, like a serious burn, electric shock leading to loss of consciousness, or other specified injuries, must be reported. Dangerous occurrences, such as electrical short circuits causing fire or explosion, or the collapse of equipment, are also notifiable under RIDDOR. Over-seven-day injuries are common in this trade and must be reported if they prevent normal work for more than a week.

Why Does This Matter?

Accurate and timely RIDDOR reporting helps identify hazards, prevent future incidents, and demonstrates your commitment to health and safety. For construction workers, plumbers, gas engineers, and electricians, it’s a legal duty that protects you, your colleagues, and the public.

If you’re unsure whether an incident is reportable, always err on the side of caution and consult the HSE’s official guidance or reach out to your health and safety officer.

Common RIDDOR Mistakes (And How to Avoid Them)

One of the most common RIDDOR mistakes is not recognising which incidents are actually reportable. To avoid this, use a clear checklist or flowchart so you can quickly determine whether an event meets the RIDDOR criteria. Missing reporting deadlines is another frequent pitfall, but setting up reminders or using automated systems can help ensure you never let a report slip through the cracks.

Under-reporting near-misses is also a significant issue; regular training will help your team spot and report dangerous occurrences before they escalate into something more serious. Poor record keeping can lead to compliance headaches and lost information, so make sure you centralise and securely store all RIDDOR-related records. Finally, don’t focus solely on immediate injuries. Remember to track and report long-term conditions and occupational diseases, as these are just as important for workplace safety and legal compliance.

What Happens If You Don’t Comply?

Non-compliance isn’t just a slap on the wrist. Those who don’t comply with RIDDOR can face:

Fines and legal action: The HSE can and will prosecute.
Insurance headaches: Claims may be denied if you haven’t followed RIDDOR.
Reputational damage: No one wants to work for a company that ignores safety.
Prison: In extreme cases, custodial sentences are possible.

Final Word

RIDDOR is a vital tool for making workplaces safer, more transparent, and ultimately more productive. By understanding your responsibilities and embedding RIDDOR processes into your daily operations, you’re not just ticking a legal box; you’re actively contributing to a culture of safety that protects your team, your business, and the wider public.

For construction workers, plumbers, gas engineers, and electricians, the risks on site are real and ever-present. Prompt and accurate reporting of incidents under RIDDOR doesn’t just help you stay on the right side of the law; it also provides valuable data that can be used to prevent future accidents, improve training, and drive up standards across the industry.
