This website gives information on the regulation of health and safety for the natural gas supply industry. It outlines how the hazards and risks posed by the network are controlled and describes what HSE are doing to work with industry to achieve this.

The information is aimed at duty holders who work in the gas supply industry as well as gas consumers, stakeholders and others who may be affected by it.
