  • What we do in the Gas Industry

    • All gas in the UK passes through National Grid’s national transmission system on its way to consumers. As the sole owner and operator of gas transmission infrastructure in the UK, we work with other companies to ensure that gas is available where and when it’s needed.

      !n the UK, gas leaves the transmission system and enters the distribution networks at high pressure. It is then transported through a number of reducing pressure tiers until it is finally delivered to consumers. There are eight regional distribution networks, four of which are owned by National Grid.

      Gas is owned by your gas supplier, however, National Grid is responsible for this gas whilst it is being transported.

      Our UK distribution networks deliver gas to around 10.9 million consumers.

      LNG CareersWhat are the main functions of the UK gas industry?

      There are four main elements:

      •  Production and importation – gas comes from offshore fields in the North and Irish seas. It’s also brought over from Ireland, Belgium and the Netherlands via three interconnector pipes and imported in the form of liquefied natural gas (LNG). A small amount is produced on shore, too. Gas producers, LNG importers and interconnector operators bring the gas on shore to reception terminals and LNG importation terminals. National Grid owns and operates an LNG importation terminal in Kent.
      •  Transmission – National Grid is the sole owner and operator of gas transmission infrastructure in the UK. Gas producers supply gas to our national transmission system (NTS) through reception terminals. Gas from the importation terminals is injected into the NTS after quality checks. Also, gas that’s been held in storage can be reintroduced into the system. Our compressor stations keep the gas flowing through the system.
      •  Distribution – gas leaves the NTS at 49 points across the UK. It’s odorised for safety then transported in the distribution networks for final delivery to consumers. There are eight regional distribution networks in the UK, four owned by National Grid and four by other companies.
      •  Supply – whichever gas supplier they choose, gas is delivered to most consumers’ premises through a pipe belonging to the local distribution network. Our distribution networks deliver gas to around 10.8 million consumers.

  • What we don't do

    • We don’t produce gas for the UK market.
    • We don’t own the gas that is conveyed through our national transmission and distribution networks.

    Who pays for what?

    Gas producers and importers sell gas to licensed shippers who then own the gas as it travels through the transmission and distribution networks.

    Shipping involves buying gas from the producers, arranging for it to be conveyed to supply points (via our NTS) and selling it to gas suppliers. We are not a gas shipper.

    Shippers pay us to run their gas through our national transmission network and LNG importers pay for the right to land LNG at our importation terminals.

    Shippers also pay National Grid and other gas distribution network operators to transport their gas to homes and businesses. These charges are passed on to consumers and reflect the cost of building, maintaining and operating the networks and running a 24-hour gas emergency helpline.

    Gas consumers – homes and businesses throughout the UK – have many gas supply companies to choose from. The supply companies pay the gas shippers who buy gas and arrange for it to be transported.
