All about RIDDOR reporting | Injuries & Report Submission

The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR) set out legal duties for employers, people who are self-employed and people who control premises to notify and report specified work-related events. By embedding comprehensive reporting procedures, organisations can satisfy regulatory requirements, drive proactive risk management and demonstrate that they are committed to protecting their workers and members of the public.

In this article, we will explore each aspect of RIDDOR compliance in depth – its history, scope, practical procedures and strategic integration – so you can transform a legal obligation into a catalyst for continuous improvement.

What is RIDDOR? An overview

RIDDOR regulations represent the UK’s statutory framework for capturing data on serious workplace incidents. Originating from regulations introduced in 1985 and updated in 1995 and 2013 to reflect evolving work-related hazards, RIDDOR derives its authority from the Health and Safety at Work etc. Act 1974. It has three main purposes:

Information gathering – by mandating notifications of certain events, RIDDOR provides the Health and Safety Executive (HSE) and local authorities with an evidence base to monitor trends, identify high-risk sectors and direct enforcement resources effectively.
Prevention and learning – analysis of reported incidents, ranging from major injuries to dangerous “near misses”, uncovers root causes and hidden failures. Sharing these insights across an industry helps prevent recurrence.
Legal accountability – dutyholders who fail to report qualifying incidents may face enforcement action. Transparent incident management is crucial.

RIDDOR applies across virtually all workplaces in Great Britain, including offices, factories, construction sites, agricultural holdings and retail outlets. Northern Ireland has separate but similar regulations. For the latest official guidance and downloadable reporting forms, refer to the HSE RIDDOR portal.

Why reporting matters: Safety and legal accountability

Driving a positive safety culture

Effective RIDDOR reporting is a barometer of an organisation’s safety maturity. When incidents are logged and analysed, stakeholders – from frontline workers to senior executives – gain visibility of real hazards, ultimately leading to better safety.

This transparency empowers teams to engage in meaningful discussions about controls, behaviours and design improvements, reinforcing a culture where safety concerns are raised without fear of blame.

Fulfilling legal obligations

Under RIDDOR, failure to notify or report a qualifying incident constitutes a breach.

Enforcement action can include improvement or prohibition notices, financial penalties and, in extreme cases, prosecution for organisations and individuals. It’s not uncommon for courts to hand out six-figure fines for companies that conceal serious incidents or display systemic neglect.

In contrast, timely reporting and full cooperation with inspectors often mitigate the severity of enforcement action.

Supporting corporate governance and insurance

Investors, insurers and corporate auditors increasingly scrutinise health and safety performance as part of environmental, social and governance (ESG) criteria. A robust RIDDOR record demonstrates that an organisation has done its due diligence and is aware of risks. This can lead to more favourable insurance terms and enhance the organisation’s reputational standing.

It’s also important to remember that clear documentation of incident investigations and corrective actions supports the organisation’s defence against civil claims.

Who must report under RIDDOR?

Employers

Any organisation that employs staff – whether full-time, part-time, casual or agency – bears RIDDOR duties. Limited companies, partnerships, charitable organisations and public bodies are all included.

Employers are responsible for the health and safety of every individual they pay, including contractors.

Self-employed people

Individuals who carry out work activities in a self-employed capacity must report incidents that affect themselves or others.

Typical examples include building contractors, waste-management operatives, agricultural workers and independent consultants whose tasks involve physical risks.

People in control of work premises

Those who manage premises where work takes place must also report incidents that occur on their sites. This affects facilities managers, landlords of business parks or proprietors of multi-occupancy buildings, among other individuals.

Even if a tenant or contractor conducts the immediate work, the premises controller is responsible for reporting in cases where hazards occur due to structural or service deficiencies (e.g., if a wall collapses or electrical installations fail).

Shared responsibilities

Clarity is essential on complex sites, such as construction projects with principal contractors and multiple subcontractors. Each party must determine its sphere of control and agree in writing which incidents each will report. This helps avoid duplication or gaps.

This is often achieved through site induction packs, project health and safety plans and formal subcontractor agreements.

What types of incidents are reportable?

RIDDOR categorises reportable events into four broad groups, each with its own thresholds and definitions. Dutyholders should be familiar with all the categories so nothing that needs reporting slips through the cracks.

Work-related injuries
- Fatalities and specified major injuries
- Injuries leading to more than seven days’ incapacitation
Occupational diseases
- Conditions diagnosed by a registered doctor and attributed to exposure in the workplace
Dangerous occurrences
- “Near misses” that had potential to cause significant harm, even if no injury occurred.
Work-related deaths
- Any fatality arising from a work activity, including deaths due to occupational disease or accidents involving members of the public.

A rigorous internal process – typically led by health and safety managers or designated supervisors – should screen all incidents against these criteria. If there’s doubt, the HSE encourages dutyholders to seek clarification rather than risking non-compliance.

Injuries that must be reported

Major injuries

Schedule 1 of RIDDOR lists specific injuries that are severe enough to warrant immediate reporting. These include, but are not limited to:

Fractures, excluding those of fingers, thumbs and toes
Amputations of limbs or digits
Serious burns covering more than 10% of body surface or affecting the eyes, respiratory system or other vital organs
Loss of sight (temporary or permanent)
Crush injuries leading to internal organ damage
Any injury requiring hospital admission for more than 24 hours

Reporting must occur without delay – ideally within 10 days – via phone. This must be followed by an online submission. Case law demonstrates that prompt notification is critical to preserving evidence and enabling timely HSE intervention.

Over-seven-day injuries

An injury is reportable if the injured person is unable to perform their normal work duties for more than seven consecutive days, excluding the day of the incident but including weekends and rest days.

Monitoring systems – such as return-to-work interviews and absence registers – must flag any employee whose sickness absence crosses the seven-day threshold.

Reports for over-seven-day injuries are due within 15 days of the incident.

Practical example

A warehouse operative fractures a wrist when a pallet stack collapses. While the fracture does not require more than 24 hours’ hospitalisation, the injured worker is off duty for 12 days. This meets the over-seven-day criterion and must be reported online within the 15-day window.

Reportable occupational diseases

Occupational diseases often have long latency periods, complicating attribution. RIDDOR requires a report when a doctor diagnoses a listed condition and believes it was probably caused or made worse by work.

Key diseases include:

Carpal tunnel syndrome and other repetitive strain injuries caused by prolonged typing, assembly-line tasks or the use of hand-held power tools
Occupational asthma triggered by exposure to flour dust, isocyanates, wood dust or other respiratory sensitisers
Hand-arm vibration syndrome (HAVS) resulting from the use of vibrating machinery such as pneumatic drills or grinders
Dermatitis caused by contact with skin irritants (e.g., solvents, detergents) or sensitisers (e.g., chromates)
Noise-induced hearing loss, where audio testing confirms a permanent threshold shift caused by work-related noise
Occupational cancer, including mesothelioma from asbestos exposure or lung cancer linked to crystalline silica dust

Once a condition is diagnosed, the employer must file a report within 15 days. In practice, it helps to keep close contact with occupational health providers and encourage employees to let their line manager know right away if they receive such a diagnosis.

Dangerous occurrences explained

Dangerous occurrences capture high-potential near misses that didn’t cause harm but reveal significant system weaknesses. RIDDOR’s Schedule 2 lists 27 categories, including:

Collapse or failure of lifting equipment
Explosions or fires that cause normal work to be suspended
Accidental release of flammable liquids or gases
Structural failures of cranes, scaffolding or derricks
Exposure to biological agents with the potential for serious health effects

Although none of these events may cause injury, they point to hidden defects in equipment, procedures or design. Investigating and reporting near misses contributes to a learning culture, enabling organisations to implement corrective controls – such as enhanced maintenance regimes or revised emergency procedures – before something more serious happens.

Immediate notification

Any work-related fatality must be notified to the HSE Incident Contact Centre without delay – ideally by phone within 24 hours – followed by an online report within 10 working days. This includes:

Deaths due to accidents on site or while travelling for work
Fatalities from occupational diseases
Deaths of members of the public resulting from work activities

Legal implications

Fatal incidents trigger mandatory inquiries by the HSE and often involve coroners. They may also trigger investigations under the Corporate Manslaughter and Corporate Homicide Act 2007, exposing organisations and senior staff members to criminal liability where gross negligence is proven.

Example scenario

A delivery driver suffers a fatal head injury due to a fall on icy premises. The employer must immediately notify the HSE, preserve the scene for investigators and liaise with emergency services. Swift action ensures that inspectors can secure evidence and identify whether inadequate gritting procedures or vehicle maintenance contributed to the death.

Timeframes and deadlines for reporting

Here are the key timeframes for RIDDOR:

Fatalities and major injuries – phone notification within 24 hours; online report within 10 working days
Over-seven-day injuries – online report within 15 calendar days of the incident
Occupational diseases and dangerous occurrences – online report within 15 calendar days of diagnosis or occurrence

Organisations often integrate RIDDOR milestones into electronic safety-management systems, triggering automated reminders when report deadlines are approaching. Assigning clear ownership for each report – and auditing compliance quarterly – minimises the risk of late or missing submissions, which can result in enforcement notices or fines.

How to submit a RIDDOR report

Step-by-step guide

Identify the incident category
Verify whether the event qualifies as a death, major injury, over-seven-day injury, occupational disease or dangerous occurrence. You can consult the HSE RIDDOR guidance or seek advice from an accredited safety consultant if you’re unsure.
Telephone notification (if required)
For fatalities or specified major injuries, call the HSE Incident Contact Centre on 0300 003 1647. Provide concise details: the incident type, date, location, employer name and a brief description of events. The call handler will issue a report reference number.
Access the online portal
Visit the HSE’s online RIDDOR reporting system, log in or proceed as a guest and select the appropriate form.
Complete organisational details
Enter your contact information, employer name, address and Standard Industrial Classification (SIC) code. Accurate SIC codes help the HSE analyse sector-specific incident rates.
Describe the incident
Provide the date, time and location, followed by a clear, factual narrative. Include equipment involved, environmental conditions and sequence of events. Avoid jargon; use plain English.
Specify the affected person
Indicate the affected person’s status (employee, self-employed, contractor, member of the public), job role and whether the incident occurred on or off site during work activities.
Detail immediate actions
Outline first-aid administered, site shutdowns or evacuations, and remedial steps taken to secure the area.
Submit and record confirmation
After submission, you’ll receive an automated confirmation email that contains the report reference. File this alongside your internal investigation records.

Alternative routes

In Scotland, dutyholders have the option to report to their local authority rather than the HSE, depending on the type of premises.

Northern Ireland has its own reporting portal managed by the Health and Safety Executive for Northern Ireland (HSENI).

What information must be included?

A strong RIDDOR submission strikes the right balance – brief, but with enough detail for the HSE to understand the situation. Essential information comprises:

Incident identification – precise date, time and location, including site address and department or unit
Dutyholder details – the employer or self-employed person’s name, contact phone number and SIC code
Incident classification – clearly reference the RIDDOR schedule entry (e.g., “Schedule 1, Major Injury: Amputation of thumb”)
Narrative description – a concise but comprehensive account, covering the activities immediately before and during the incident, atmospheric conditions, equipment status and any safety measures in place
Information about the casualty – the injured person’s role, employment status and whether they received hospital treatment or first aid only
Preventive and corrective actions – immediate measures taken to prevent the incident from happening again, such as isolating machinery, revoking permits or enhancing supervision

Precise language reduces the need for HSE follow-up queries and speeds up their ability to prioritise inspections.

The role of the responsible person

The “responsible person” is the individual appointed by the dutyholder to prepare and submit RIDDOR reports. Their responsibilities include:

Incident screening – evaluating all serious incidents and near misses against RIDDOR criteria
Report preparation – gathering factual information, liaising with witnesses, reviewing CCTV or maintenance logs, and drafting the incident narrative
Submission and liaison – contacting the HSE Incident Contact Centre when required, completing online forms and providing additional documentation upon request
Record maintenance – ensuring confirmation references, investigation reports and corrective-action plans are archived for the statutory retention period

To ensure resilience, organisations should nominate deputies and include RIDDOR duties within job descriptions. Training – either in-house or via certified providers – helps those responsible stay up to date with changes in the legislation.

Record-keeping requirements

Even when an incident doesn’t meet the RIDDOR reporting thresholds, it should still be documented as part of a strong safety management system. For reportable events, organisations must keep the following:

RIDDOR confirmation emails and reference numbers
Internal investigation reports, including root-cause analyses and witness statements
Corrective-action plans showing how risks were mitigated
Training records updated in response to findings (e.g., retraining on manual-handling techniques)

Keep records for at least three years from the date of the incident. Electronic safety-management platforms enable easy retrieval and trend analysis. They also make it simple for reports to be integrated with audit schedules.

Under the UK GDPR, personal data within these records must be handled securely, with access controls and appropriate retention policies.

RIDDOR and incident investigations

RIDDOR reporting dovetails with structured incident investigations. Best practice involves:

Immediate scene preservation – secure the area, isolate equipment and preserve any physical evidence.
Evidence collection – interview witnesses promptly, capture photographs and review maintenance logs or health-monitoring data.
Root-cause analysis – apply techniques such as the “5 Whys”, fault-tree analysis or fishbone diagrams to trace back to underlying system failures. For example, these might be procedural, human-factor or technical.
Action planning – develop SMART (specific, measurable, achievable, relevant, time-bound) corrective actions, assigning clear owners and deadlines.
Communication and training – share the findings with affected teams via strategies like toolbox talks. Make updates to operating procedures and provide refresher training sessions.
Verification – conduct follow-up inspections and audits to confirm that actions have been implemented and remain effective.

When reporting under RIDDOR, incorporate investigation findings to present regulators with a clear picture of causes and controls, reducing the likelihood of extensive HSE queries.

Integration with risk assessments and safety policies

A sophisticated health and safety management system treats RIDDOR as a feedback loop within the broader plan-do-check-act (PDCA) cycle. Key integration points include:

Risk assessments – update risk assessments to reflect hazards that RIDDOR incidents have revealed. For instance, they might be mechanical failures, poor ergonomic design or process deviations.
Safety policies – embed lessons learned into formal policies, such as permit-to-work systems, emergency-response plans and contractor management procedures.
Training and competence – incorporate incident case studies into training modules, emphasising human-factor considerations and reinforcing safe behaviours.
Performance monitoring – track RIDDOR metrics alongside audit scores, near-miss reports and leading indicators (e.g., safety observations) to gauge the effectiveness of interventions.

Aligning RIDDOR outcomes with international standards – like the ISO 45001 Occupational Health and Safety Management Systems – shows the organisation is committed to continual improvement. It also facilitates integration with other management systems (quality, environment).

Enforcement and penalties for non-compliance

HSE powers

Inspectors have wide-ranging powers under RIDDOR. In the event of non-reporting or late submission, they may issue:

Improvement notices, mandating specified corrective actions within a set timeframe
Prohibition notices, halting activities that pose an immediate risk
Prosecutions, leading to unlimited corporate fines and potential criminal records for responsible individuals

Case law example illustrations

A construction worker suffered a traumatic leg amputation after an excavator tipped over on site in January 2019. The incident was not reported to the regulator within the required 10 days under RIDDOR, and only came to light following a complaint months later. By then, a proper investigation was no longer possible. The employer had also failed to provide adequate health and safety procedures or compulsory liability insurance.

The court found high culpability, noting cost-cutting at the expense of safety, delayed improvements and lack of remorse. The employer was sentenced to 24 weeks’ immediate custody and ordered to pay costs.

Recent prosecutions have seen organisations fined hundreds of thousands of pounds for concealing major injuries or failing to report dangerous occurrences that resulted in severe harm. In one landmark case, a manufacturing firm received a £500,000 fine after a near-miss explosion – caused by inadequate ventilation of solvent vapours – went unreported, and a subsequent incident injured two workers.

Mitigating enforcement risk

To demonstrate proactive compliance and reduce enforcement exposure:

Maintain up-to-date RIDDOR records and register them in internal dashboards.
Cooperate fully with inspectors, providing clear documentation and investigation reports.
Implement audit programmes that include RIDDOR compliance checks.
Conduct periodic mock drills of the reporting process to test how responsive they are.

Building RIDDOR reporting into your health and safety approach is about treating each notification as an opportunity to learn, adapt and strengthen controls. Done well, it protects your most valuable asset: your people. It also builds trust with stakeholders and keeps you on the right side of the law. Clear roles, good training, lessons fed into risk assessments, and careful record-keeping all help.

In this way, RIDDOR becomes a tool for creating safer, stronger and more resilient workplaces.
