Learn how to report asbestos incidents under RIDDOR in 2025. Understand legal duties, exposure risks, and how to stay compliant with UK law.
Asbestos exposure incidents remain a major concern across the UK, especially in older buildings and commercial spaces. The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 (RIDDOR) makes it mandatory to report certain types of asbestos breaches. Property owners, contractors, and employers must understand when and how to report, or risk legal penalties and health consequences. This guide explains how RIDDOR applies to asbestos in 2025 and how to stay compliant.
What Is RIDDOR and Why Does It Apply to Asbestos?
RIDDOR requires responsible parties to notify the Health and Safety Executive (HSE) of specific workplace incidents. It applies to asbestos when fibres are accidentally released or exposure occurs under unsafe conditions. Even single-event exposures can fall under these regulations if there’s a risk to health due to failure in control measures.
It applies because asbestos exposure is classified as a dangerous occurrence. Employers must report when workers are exposed due to procedural failure, absence of PPE, or accidental disturbance of asbestos-containing materials.
Which Asbestos Incidents Must Be Reported Under RIDDOR in 2025?
The following situations usually require reporting:
- Disturbance of asbestos materials during work without adequate controls
- Exposure due to damaged or deteriorating asbestos where occupants are at risk
Not all asbestos incidents require a report. For example, discovering asbestos without any disturbance or exposure does not qualify. Misreporting non-events wastes HSE resources and dilutes attention from genuine risks.
Who Is Legally Responsible for Reporting Asbestos Breaches?
The duty to report rests on employers, building managers, landlords, and duty holders. If a contractor uncovers and disturbs asbestos, the main contractor or site manager may also share liability.
In multi-tenant buildings, coordination is key. Whoever controls the work or space is usually responsible. Ignoring this responsibility can lead to prosecution and fines.
How Do You Report an Asbestos Incident Under RIDDOR?
Reporting must be done through HSE’s online system. In cases of severe injury or fatality, reports can be made by phone. A typical report includes:
- Date and location of incident
- Details of exposure: type, duration, number of individuals affected
- Control failures or lack of training that led to exposure
The law requires reports to be filed within 10 days of the incident unless the exposure caused a death, which must be reported immediately.
What Are the Health Risks That Make Asbestos Exposure Reportable?
Asbestos exposure causes serious and sometimes fatal diseases. These include:
- Mesothelioma and lung cancer, often developing decades after exposure
- Asbestosis, a condition marked by lung scarring and difficulty breathing
Even brief or low-level exposure can pose future health risks if fibre levels are high or repeated. RIDDOR acknowledges that single breaches can have long-term effects.
What Evidence Do You Need Before Filing a RIDDOR Report?
HSE requires detailed, fact-based evidence that supports your claim. Air monitoring results are one of the strongest forms of proof, especially when fibre levels breach control limits. Witness statements help establish the sequence of events and whether safe systems were in place. Photographs of the area, especially those showing disturbed materials or damaged containment, add visual support. Documentation from your asbestos register, contractor logs, and previous survey records show whether known risks were being managed. Keeping a clear paper trail reflects how seriously your site treats asbestos control.
What Happens After a RIDDOR Report Is Filed?
Once submitted, HSE reviews the report to determine risk severity and breach type. If the case is serious, inspectors may request internal documents, training records, and logs. They may visit the site and speak to workers. If the incident shows failure to follow asbestos protocols, legal consequences are possible. Having a current management plan, updated surveys, and evidence of staff awareness puts you in a stronger position during review.
How Can You Prevent Reportable Asbestos Incidents?
Most asbestos breaches are avoidable. Preventive steps include:
- Conducting asbestos surveys before any work begins
- Ensuring contractors are trained and briefed on site risks
Update your asbestos register regularly and avoid any DIY testing or removal. All staff, especially those in maintenance roles, should receive asbestos awareness training.
What Are the Legal Penalties for Failing to Report Under RIDDOR?
Failing to report can result in:
- Fines ranging from fixed penalties to unlimited court fines
- Personal prosecution of directors or managers for neglect
Repeated offences or falsified documentation escalate risks. Insurance cover may also be lost if exposure was concealed or unmanaged.

RIDDOR compliance is about transparency and prevention. By reporting asbestos exposure correctly, you reduce harm, show legal responsibility, and avoid further penalties. Keeping good records, training teams, and acting fast after incidents are your best defence against costly legal consequences.
Frequently Asked Questions
No. Only exposure incidents where fibres are released or safety procedures fail must be reported.
Symptoms may take decades. RIDDOR reporting is still required based on exposure risk, not health outcome.
Yes. Self-employed individuals must report their own exposure if working on another client’s premises.
Submit a basic report first to meet the deadline, then follow up with supporting documentation.
Not through RIDDOR, but employees can report concerns via HSE’s confidential channels.
The duty holder should assess evidence. If in doubt, it’s safer to report and let HSE decide.
