Changes to the Reporting of Injuries, Diseases and Dangerous Occurrences Regulations (RIDDOR) 1995 mean that employers no longer have to report injuries which keep workers off normal duties for seven or fewer days.
The change in legislation was introduced on 6 April and, according to the Health and Safety Executive (HSE) could reduce by 30% the number of incidents that must be reported by law.
In addition, employers will also now be given a longer period in which to report, increasing from 10 to 15 days from the time of the incident.
By increasing the reporting threshold from three to seven days, the change will align with the 'fit note' system which ensures that someone who is off work because they suffered a reportable injury has a professional medical assessment.
Employers and others with responsibilities under RIDDOR must still keep a record of all over three day injuries, for example through an accident book.
HSE Chair Judith Hackitt said:"The change to the RIDDOR regulations will cut paperwork, help employers manage sickness absence and ensure that the reporting system is focused on risks which have resulted in more serious injury.
"This is just one of many changes we are making to the health and safety system to make it simpler, clearer and more easily understood - stripping unnecessary paperwork out of the system without compromising essential protections for workers."
The change to RIDDOR was recommended in the Government commissioned Common Sense, Common Safety report.
