RIDDOR stands for the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013. It is the UK law that requires employers, the self-employed, and those in control of premises to report specific work-related incidents to the HSE.

What injuries are RIDDOR-reportable?

RIDDOR-reportable injuries include fractures (excluding fingers, thumbs, and toes), amputations, permanent loss of sight, crush injuries causing internal organ damage, serious burns, scalping, unconsciousness due to head injury or asphyxia, and any injury requiring hospital admission for more than 24 hours. Over-7-day incapacitation injuries are also reportable.

How do I report a RIDDOR incident?

RIDDOR reports are submitted online via the HSE's RIDDOR reporting website. Fatal and specified injuries should also be reported immediately by telephone to the HSE Incident Contact Centre on 0345 300 9923. All online reports must be submitted within the required timeframes.

What are the RIDDOR reporting deadlines?

Deaths and specified injuries must be reported immediately (without delay). Over-7-day incapacitation injuries and dangerous occurrences must be reported within 15 days. Reportable occupational diseases must be reported within 15 days of the diagnosis being notified to the employer.

Is accident investigation legally required?

Yes. Under the Management of Health and Safety at Work Regulations 1999, employers must investigate workplace incidents to identify root causes and prevent recurrence. A thorough investigation is also essential to defend against HSE enforcement action and civil claims.

What happens if a RIDDOR incident is not reported?

Failure to report a RIDDOR-reportable incident is a criminal offence. It can result in HSE enforcement action, prosecution, unlimited fines, and increased scrutiny of your organisation. Late reporting can also be treated as an offence.

Who is responsible for RIDDOR reporting?

The employer, self-employed person, or person in control of the premises where the incident occurred is responsible for RIDDOR reporting. For employees, it is the employer's duty. For non-employees (e.g. visitors, members of the public), it is the duty of the person in control of the premises.

What is a dangerous occurrence under RIDDOR?

A dangerous occurrence is a specified near-miss event that had the potential to cause serious harm — such as the collapse of scaffolding, failure of load-bearing parts of lifts, explosions or fires causing work stoppage, uncontrolled release of flammable substances, or electrical incidents causing fire.

What occupational diseases are reportable under RIDDOR?

Reportable occupational diseases include carpal tunnel syndrome, occupational dermatitis, hand-arm vibration syndrome (HAVS), occupational asthma, tendonitis or tenosynovitis, occupational cancer (e.g. mesothelioma), and diseases caused by biological agents. They must be reported when diagnosed by a doctor and linked to the work carried out.

Can Arinite submit RIDDOR reports on our behalf?

Yes. Arinite can prepare and submit RIDDOR reports accurately and compliantly on your behalf, ensuring correct classification, appropriate detail, and timely submission. We also provide the supporting investigation report.

Does reporting a RIDDOR incident trigger an HSE investigation?

Not always. The HSE uses a risk-based approach to decide which incidents to investigate. However, fatalities, multiple-injury incidents, serious specified injuries, and incidents involving poor compliance history significantly increase the likelihood of an HSE investigation.

What are the penalties for not complying with RIDDOR?

Penalties include unlimited fines for organisations, up to 2 years' imprisonment for individuals under the Health and Safety at Work Act 1974, HSE enforcement notices, and civil liability. Directors and senior managers can be personally prosecuted for consent, connivance, or neglect of safety duties.

What records must I keep under RIDDOR?

Employers must keep records of all RIDDOR-reportable incidents for at least 3 years. Records should include the date, time, and location of the incident, details of the injured person, the nature of the injury or disease, a description of what happened, and any action taken. An accident book or incident log system should be maintained.

HSE inspections up 47% - HSE carried out over 13,200 workplace inspections in 2024/25.

Accident Investigation & RIDDOR Reporting

RIDDOR Reporting, Accident Investigation & Legal Compliance

When a serious workplace accident occurs, what you do next determines your legal exposure.

Under the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 (RIDDOR), employers, the self-employed, and those in control of premises have strict legal duties to report, record, and investigate specific work-related incidents. RIDDOR reports are submitted to the Health and Safety Executive (HSE) and form part of the national picture of workplace health and safety.

Failure to comply with RIDDOR can result in:

HSE enforcement action — improvement and prohibition notices
Criminal prosecution under the Health and Safety at Work Act 1974
Unlimited fines for organisations and individuals
Increased HSE scrutiny and more frequent inspections following future incidents
Directors' personal liability for health and safety failings

Arinite provides professional accident investigation and RIDDOR reporting services, helping organisations meet their legal obligations, protect directors from personal liability, and prevent incidents from recurring.

What Is RIDDOR?

RIDDOR stands for the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013. It is the UK regulation that requires specific work-related accidents, occupational diseases, and dangerous occurrences (near misses) to be formally reported to the HSE or the relevant enforcing authority (usually the local authority for offices, shops, and leisure premises).

The HSE uses RIDDOR reports to:

Identify serious workplace risks and emerging trends
Detect patterns of failure across industries and sectors
Decide when to investigate incidents or prosecute dutyholders
Inform national workplace health and safety statistics and policy

Incorrect, late, or incomplete RIDDOR reporting — or failure to investigate properly — can significantly increase your legal exposure and the likelihood of HSE enforcement action.

Who Has Duties

Who Has Duties Under RIDDOR?

RIDDOR reporting duties apply to:

Employers — for incidents involving their employees
Self-employed persons — for incidents arising from their work
Those in control of work premises — for incidents involving anyone affected by the premises (including visitors and members of the public)

This includes responsibility for incidents affecting:

Employees and workers
Contractors and sub-contractors
Visitors and customers
Members of the public affected by work activities

Reportable Incidents

What Must Be Reported Under RIDDOR?

Specific categories of incidents must be reported when they arise out of, or in connection with, work. Not all workplace injuries are RIDDOR-reportable — the regulations specify exactly which incidents require a formal report.

Work-Related Deaths

All deaths to workers and non-workers must be reported to the HSE if they result from a work-related accident, including acts of physical violence to workers.

Specified Injuries (to Workers)

The following specified injuries to workers must be reported:

Fractures — excluding fingers, thumbs, and toes
Amputations — loss of any limb or part of a limb
Permanent loss or reduction of sight
Crush injuries causing internal organ damage
Serious burns — covering more than 10% of the body or affecting the eyes, respiratory system, or vital organs
Scalping — requiring hospital treatment
Unconsciousness — caused by head injury or asphyxia
Any injury requiring resuscitation or admission to hospital for more than 24 hours

Over-7-Day Incapacitation

Where an employee is incapacitated — unable to carry out their normal work duties — for more than 7 consecutive days (not counting the day of the accident). The report must be made within 15 days of the accident.

Reportable Occupational Diseases

Certain occupational diseases must be reported when diagnosed by a doctor and linked to the type of work carried out:

Carpal tunnel syndrome
Severe cramp of the hand or forearm (writer's cramp)
Occupational dermatitis
Hand-arm vibration syndrome (HAVS)
Occupational asthma
Tendonitis or tenosynovitis of the hand or forearm
Occupational cancer (e.g. mesothelioma, bladder cancer from workplace carcinogens)
Any disease attributable to a biological agent

Dangerous Occurrences (Near Misses)

Specified dangerous occurrences — incidents that did not result in injury but could have caused serious harm — must be reported:

Collapse, overturning, or failure of load-bearing parts of lifts, cranes, or scaffolding
Explosions or fires causing work stoppage for more than 24 hours
Uncontrolled release of flammable liquids or gases
Electrical short circuit or overload causing fire or explosion
Accidental release of dangerous biological agents
Collapse or partial collapse of a building or structure

Gas Incidents

Gas-related incidents resulting in death, loss of consciousness, or hospital treatment must be reported by the registered gas engineer involved. This applies to incidents involving piped natural gas and LPG.

Reporting Deadlines

RIDDOR Reporting Deadlines & How to Report

Strict reporting deadlines apply depending on the type and severity of the incident. Reports are submitted online via the HSE's RIDDOR reporting website or by telephone for fatal and specified injuries.

Immediate Reporting — Without Delay

Without delay (as soon as possible)

All work-related deaths
All specified injuries to workers

These must be reported immediately — usually by telephone to the HSE Incident Contact Centre (0345 300 9923) followed by a written online report within 10 days.

15-Day Reporting

Within 15 days of the incident

Over-7-day incapacitation injuries
Dangerous occurrences

15-Day Reporting (Diseases)

Within 15 days of diagnosis

Reportable occupational diseases — when a doctor notifies you of the diagnosis and it is linked to work

Late or missed RIDDOR reporting is itself an offence and increases the likelihood of HSE enforcement action.

Investigation Importance

Why Accident Investigation Is Critical

RIDDOR reporting is only one part of your legal duty following a workplace incident.

A thorough, documented accident investigation is essential to:

Demonstrate compliance with the Management of Health and Safety at Work Regulations 1999
Identify root causes — not just immediate causes
Prevent recurrence through corrective and preventive actions
Defend against HSE enforcement action, criminal prosecution, and civil claims
Protect directors and senior managers from personal liability

The HSE frequently criticises inadequate investigations during prosecutions. A well-documented investigation demonstrates that you took your health and safety duties seriously.

OUR PROVEN SYSTEM

The Arinite Transformation™

From Reactive Firefighting to Proactive Health & Safety Compliance

STAGE 1

REACTIVE(Where 60% of Businesses Operate)

No formal HSE systems in place. Everything is reactive, waiting for something to go wrong. Documentation is missing or outdated.

Why It's Dangerous:

✗£50K-£150K average fine when (not if) HSE inspects
✗Can't bid on contracts requiring HSE certification
✗One accident away from director prosecution

This isn't just "non-compliant." It's criminally negligent. Directors face personal prosecution.

STAGE 2

COMPLIANCE(Where Most Businesses Stop)

Basic HSE documentation is in place. Minimum legal requirements met. You can pass a basic audit.

Why It's Better (But Not Enough):

✓Legal protection (no fines if inspected)
✓Can bid on contracts requiring certification
✓Pass basic client audits
✗Still reactive (problems arise, then you respond)
✗Compliance maintained by one person (bottleneck)
✗Systems don't run themselves

Compliance is where most consultants get you, then leave. You're legal, but you're not optimised.

STAGE 3

PROACTIVE(Where Arinite Clients Operate)

Systems run proactively, preventing problems before they occur. Compliance is distributed, not dependent on one person.

Why It's Transformational:

✓Win more contracts (HSE certification opens doors)
✓Save 20+ hours/week (systems run themselves)
✓Peace of mind (sleep soundly, without the fear of prosecution)
✓Focus on your core business while we handle compliance

That's why 95%+ of clients renew year after year.

The Arinite Difference:

”

Robert Winsloe

Managing Director, Arinite

“We work with you to deliver peace of mind. We tailor our service provision to your business to provide proactive, pragmatic health and safety advice and that helps reduce costs by ensuring compliance with relevant health and safety legislation.”

Other Consultants

Arinite

Gets you to Stage 3 (Proactive) and keeps you there.

That's why we call it transformation, not just compliance.

CONSULTANTS + SOFTWARE

Where Health and Safety Consultants
Meet Compliance Software.
Globally.

Health & Safety Consultants+EHS Software+Arinite AI

Consultants+EHS Software+Arinite AI

Traditional consultancies audit, report, and leave. You get a document and the job of implementing it.

Software companies give you dashboards and workflows, but no expertise. The platform stores whatever you put in it - Bad data in, Bad data out.

Arinite exists because global businesses need consultants who know compliance in every jurisdiction, and technology that proves it in real time.

We are not a consultancy that added software. We are not a software company that recommends consultants.

We are the place where those two things finally became one.
