Gas Safety (Management) Regulations

Last updated: 18 May 2022

These regulations apply to the conveyance of natural gas through pipes to consumers and include the safe management of gas flow through a network. A network begins from a gas processing facility, storage facility, or an interconnector, except a connected network of pipes used exclusively for conveying gas to non-domestic premises. 


All gas transporters are required to prepare a safety case, submit it to the Health and Safety Executive (HSE), and have it approved before beginning operations. The safety case must be kept up to date and take account of alterations to the gas transporters’ system, method of operation, management structure, and other aspects. Significant changes must be submitted to the HSE for approval. Furthermore, whether altered or not, safety cases must be reviewed every three years with a report sent to the HSE (regulation 9(1)(e)).


In the case of gas escaping into the atmosphere from the network, the operator of that part of the network must, as soon as is reasonably practicable after being informed of the escape, attend the place and, within 12 hours of being so informed of the incident, prevent the gas escaping.
