  • Who supplies gas?

  • What is National Grid’s role within the gas industry?
    The role of National Grid and other distribution network companies is to transport gas through their pipelines to your property.

    National Grid does not sell gas.

    The gas in your home or business is supplied to you by a Gas Supplier.  Only suppliers licensed by Ofgem (Office of Gas and Electricity Markets - see can sell you gas. You can more information about who supplies gas in your area from the Energy Networks Association website.

    If you know that you do not have an existing gas service or service pipe at your home or premises please refer to the Connections section of this website.

    If you do not have a gas meter yet or you cannot find the information on your bill, please call the M Number enquiry line on 0870 608 1524* and ask them for your MPRN (Meter Point Reference Number) which is the unique identifier for your gas supply point and also the identity of the current registered gas supplier at your premises.

    *0870 numbers will cost 7 per minute plus your phone company’s access charge

    *All calls to the National Gas Emergency Service and National Enquiry lines may be recorded and monitored.

  • Who does 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.
  • The network code

  • The Uniform Network Code is the hub around which the competitive gas industry revolves, comprising a legal and contractual framework to supply and transport gas. It has a common set of rules for all industry players which ensure that competition can be facilitated on level terms. Network Code came into effect in March 1996 after two years of negotiation between Transco and the shippers.

    In 2005 as a result of the sale of four of the gas distribution networks, the Network Code was replaced by the Uniform Network Code (UNC). The UNC is managed by the Joint Office of Gas Transporters.
