Over-seven-day incapacitation of a worker Accidents must be reported where they result in an employee or self-employed person being away from work, or unable to perform their normal work duties, for more than seven consecutive days as the result of their injury. This seven day period does not include the day of the accident, but does include weekends and rest days. The report must be made within 15 days of the accident. You can do this by submitting the online form.

HSE is only able to provide generic information on health & safety issues and cannot give specific advice on individual cases, as the circumstances of each individual situation will be different. Ultimately, only the courts can give an authoritative interpretation of the law when considering the application of the Health & Safety at Work etc Act 1974 (HSWA) and the Management of Health and Safety at Work Regulations 1999 (MHSWR).

Our role requires us to ensure that duty holders comply with the above legislation, however we do not prescribe in detail how that is achieved. Because every undertaking is unique and diverse, the onus is on the duty holder to ensure that they comply with current legislation.

Our website www.hse.gov.uk contains comprehensive health and safety information and guidance, which, if followed by those in industry, will ensure that such duty holders achieve compliance with the relevant legislation.

Please be aware that HSE is not permitted to offer a health & safety consultancy service. If you feel you need to engage the services of a health & safety consultant you may wish to visit the Occupational Safety & Health Consultants Register (OSHCR), which provides information about qualified health & safety consultants – see link for information www.oshcr.org
