Reporting RIDDOR incidents

This page provides an overview of the regulatory requirement to report work-related deaths, certain work-related injuries, specific occupational diseases and specific dangerous occurrences to us. The procedure for reporting will be different depending on the type of accident or incident being reported and the seriousness.

Who to contact to report a serious incident

The ORR accident reporting line is staffed Monday to Friday 09:00 to 17:30 hours. All serious incidents occurring during these hours should be reported to ORR by telephone on 020 7282 3910.

Outside these hours, and at weekends and public holidays, serious incidents should be reported to the Department for Transport (DfT) Duty Officer on telephone 020 7944 5445.

Details to be notified

You must pass on the following details to ORR or the DfT Duty Officer:

  • your name, organisation and telephone number;
  • the date and time the incident occurred;
  • where it occurred;
  • the train involved;
  • what happened;
  • number of casualties;
  • whether the casualties were passengers, rail employees, or other members of the public eg motorist, pedestrian etc.;
  • the initial cause/influencing factors if known;
  • the line/route affected and any delays to services.

You should make a note of the name of the person you spoke to and the time you made the notification.


The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 (RIDDOR 2013) require deaths, certain injuries, specific diseases and specific dangerous occurrences, which arise out of or in connection with work to be reported to the relevant enforcing authority. All RIDDOR 2013 reports arising from work on the operational railway or on a tramway or other guided transport system, including occupational disease or diagnoses reportable under regulations 8 and 9, should be reported to ORR. All other reportable RIDDOR 2013 reports should be reported to the Health and Safety Executive (HSE).

We have produced guidance on RIDDOR 2013 pdf icon PDF, 488 Kb for the railways, tramways and other guided transport systems. The Health and Safety Executive (HSE) has produced general guidance on RIDDOR 2013 which applies to all industries on its website. If a transport system falls outside the scope of ORR's guidance please refer to HSE's general guidance.

Reporting incidents to us under RIDDOR 2013

RIDDOR 2013 require the notification to the relevant enforcing authority of all reportable injuries, fatalities and dangerous occurrences by the quickest practicable means without delay and then a written notification within 10 days. A report of all occupational diseases must be sent to the relevant enforcing authority without delay. The procedure for reporting incidents to ORR will differ according to whether you are reporting:

  • serious injuries and serious dangerous occurrences and fatalities;
  • injuries, and dangerous occurrences that are not serious; or
  • a diagnosis of an occupational disease, occupational cancer, or a diagnosis due to occupational exposure to a biological agent.
