The HSE, or the Health and Safety Executive, is the executive branch of the government, under the Department for Work and Pensions, that keeps watch for the safety of all individuals engaging in work in the United Kingdom. They inspect companies and the work conditions of their employees and create resolutions and recommendations to make things safer. They also create the national rules and regulations regarding employee safety and health welfare in the workplace.
An adult spends about a third of his or her life working. Being such a big part of one’s life, the conditions of work should be made as safe as possible. The British government understands this; that’s why the Health and Safety at Work Act was passed and enacted in 1974, creating what is now the Health and Safety Executive.
If you want to call the HSE up to report injury or a fatal incident, then you can dial the HSE phone number: 0345 300 9923.
If you wish to contact the HSE because of an emergency (fatal incident, a workplace incident resulting in multiple casualties, a major disruption that caused damage to buildings, roads and injured many), then call the officer on duty on 0151 922 9235.
