What is RIDDOR (UK)?

Let’s break down RIDDOR into bitesize chunks to help you understand what needs to be done.

First off, RIDDOR stands for the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013.

These Regulations in the UK (United Kingdom) require employers, the self-employed and those in control of premises to report specified workplace incidents.

This guidance will help clarify how RIDDOR applies and whether certain types of incident are reportable.

The HSE (Health and Safety Executive) will pass on reported information about incidents to other regulators where appropriate.

For basic information on the requirements of RIDDOR, such as, who should report, how to report and when to report, keep reading!

What is a RIDDOR Report?

As an employer, it is a legal requirement to report all incidents, no matter how big or small, as well as ill health at work.

In order to be legally compliant, a record must be kept of all incidents. Keeping RIDDOR records includes:

  • Recording all reportable accidents, injuries, illnesses, dangerous occurrences, work-related deaths and specific injuries lasting more than seven days
  • Keeping all records in a file, accident book, on a computer or a written log
  • RIDDOR reporting is done through an online reporting system via the HSE website
  • Understanding and patterns in injuries and/or accidents to be considered when undertaking risk assessments
  • Keeping all records organised and up-to-date. In the event of a work related claim, the insurance company will need to see your records – if they are not up-to-date or it is determined that there are incidents missing, this is against the law
  • All employees’ RIDDOR records must be kept strictly confidential and are stored away securely. If the records are not kept confidential and stored properly, they will not be deemed compliant with the Data Protection Act

There are specific rules and regulations in regards to the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations; aside from basic information such as keeping all records updated, the following is also important:

  • A company with more than 10 employees must have an accident book
  • Owners and/or occupiers of quarries, mines and factories must have an accident book
  • RIDDOR records must be kept for a minimum of 3 years after the date of the last incident in the book
  • It is advised that RIDDOR records are kept for 5-6 years in order to allow time for any civil litigation to be made
  • Incidents must be reported within a 10-day timeframe after the occurrence

Who should actually Report?

Only ‘responsible persons’ including employers, the self-employed and people in control of work premises should submit reports under RIDDOR.

If you are an employee (or representative) or a member of the public wishing to report an incident about which you have concerns, please refer to the HSE advice.

An employer or person in control of premises

If you are an employer

If you are an employer, you must report any work-related deaths, and certain work-related injuries, cases of disease, and near misses involving your employees wherever they are working.

If you are in control of premises,

If you are in control of premises, you must report any work-related deaths, certain injuries to members of the public and self-employed people on your premises, and dangerous occurrences (some near miss incidents) that occur on your premises.


If you are working in someone else’s work premises and suffer either a specified injury or an over-seven-day injury, then the person in control of the premises will be responsible for reporting, so, where possible, you should make sure they know about it.

If there is a reportable accident while you are working on your own premises or in domestic premises, or if a doctor tells you that you have a work-related disease or condition, then you need to report it.

For information on other types of responsible persons, see here.

RIDDOR What to Report

For most types of incident, including:

  • accidents resulting in the death of any person
  • accidents resulting in specified injuries to workers
  • non-fatal accidents requiring hospital treatment to non-workers and
  • dangerous occurrences

The responsible person must notify the enforcing authority without delay, in accordance with the reporting procedure (Schedule 1). This is most easily done by reporting online.

NB: A report must be received within 10 days of the incident.

For accidents resulting in the over-seven-day incapacitation of a worker, you must notify the enforcing authority within 15 days of the incident, using the appropriate online form.

Cases of occupational disease, including those associated with exposure to carcinogens, mutagens or biological agents, as soon as the responsible person receives a diagnosis, using the appropriate online form.

What is the specific RIDDOR information I need to record?

  • The date of reporting
  • The date, time and location of the incident
  • Personal details (name, job title etc) of the person(s) involved
  • A description of the injury, illness or occurrence

The responsible person should complete the appropriate online report form on the Health & Safety Executive’s website (or HSENI in Northern Ireland). The form will then be submitted directly to the RIDDOR database and you’ll receive a copy for your records.

More information on when, and how, to report very serious or dangerous incidents, can be found by visiting the ways to contact HSE webpage. If you want to report less serious incidents out of normal working hours, you can always complete an online form.
