SGN – what does Scotia Gas Network do?


SGN are Scotia Gas Networks and they are responsible for gas distribution in Scotland and across the South of England. This doesn’t mean that they are your supplier if you live in either of these regions, it means that they are responsible for the upkeep and maintenance of the pipes which carry gas from the national grid and deliver it to homes and businesses. The responsibility of a company like SGN ends when the pipes meet your property, with the pipes and appliances inside your home or business being the responsibility of either you or your landlord.
