What Does SGN Do?

SGN was formerly called Scotia Gas Networks and it operated as Scotland Gas Networks and Southern Gas Networks before they were all jointly branded as SGN. SGN is the gas distribution network operator for the whole of Scotland as well as the South of England and part of Northern Ireland.

Given the rural terrain of Scotland, SGN has a more diverse role than other gas distribution network operators as they manage the contracts for gas shippers and transporters who deliver gas to remote parts of Scotland.

The SGN gas distribution network serves 5.9 million homes and businesses and operates over 71,000 km of pipes. They are responsible for maintaining the gas distribution network in their regions which includes repairs, pipe replacements, and upgrades, as well as connecting new homes and businesses to the gas network.

SGN is one the four local gas distribution operators in the UK which has the largest and most diverse terrain of all the operators.

History of SGN

The gas industry in the UK prior to 1948 was made up of over a thousand separate private companies and local authority undertakings, but as a result of the Gas Act 1948, these companies were nationalised and merged into 12 regional gas boards.

In 1972 the gas industry was restructured by the Gas Act 1972 where all 12 regional gas boards were merged into one as the British Gas Corporation.

In 1986 the gas industry was privatised as part of the Gas Act 1986 and shares of British Gas were floated on the London stock market. The gas distribution business was separated out from British Gas and named Transco in 1997 and then sold by British Gas in 2000. The gas distribution network at this point was divided into eight regions.

In 2002 Transco merged with National Grid Group who operate the national gas transmission system and the electricity transmission system. In 2005 National Grid plc sold four of the eight gas distribution network areas and renamed their remaining gas distribution business as National Grid plc.

Scotia Gas Networks was formed in 2005 when Scottish and South of England gas distribution networks were purchased. The business operated under the names Scotland Gas Networks and Southern Gas Networks. In 2014 Scotia Gas Networks, Scotland Gas Networks and Southern Gas Networks were rebranded under one identity as SGN to create a better brand for its entire gas distribution business.

SGN is currently jointly owned by SSE, Ontario Teachers’ Pension Plan Board, Borealis Infrastructure, and ADIA.
