RIDDOR
The Reporting of Injuries, Diseases and Dangerous Occurrences Regulations 2013 (SI 2013/1471), known as RIDDOR, place a legal duty on responsible persons in Great Britain to report certain workplace injuries, occupational diseases and “dangerous occurrences” to the HSE or local authority.
What must be reported
Fatalities of workers or members of the public arising from a work-related accident.
Specified injuries — including fractures (other than fingers/toes), amputations, permanent loss of sight, crush injuries to the head/torso, serious burns, scalpings, loss of consciousness from head injury or asphyxia, and any injury requiring resuscitation or hospital admission >24 hours.
Over-7-day injuries — incapacitation for more than seven consecutive days (excluding the day of the accident).
Occupational diseases — including carpal tunnel syndrome, severe cramp of the hand or forearm, occupational dermatitis, hand-arm vibration syndrome, occupational asthma, tendonitis or tenosynovitis, occupational cancer and any disease attributed to biological agent exposure.
Dangerous occurrences — listed in Schedule 2 (e.g. collapse of lifting equipment, escape of flammable substances, electrical short circuit causing fire/explosion).
Gas incidents — by gas distributors and registered gas fitters.
Timing and method
Most reports are made online via the HSE RIDDOR portal. Fatalities and major incidents must be reported “without delay” by phone. Other reports must be made within 10 days for over-7-day injuries; 15 days for occupational diseases.
Insurance relevance
Employers’ liability and public liability proposal forms routinely ask for RIDDOR reports over a defined period.
RIDDOR data is the primary input to HSE statistics and to actuarial industry loss benchmarks.
Failure to report is a criminal offence; it can also damage credibility in subsequent EL/PL claim defence.
