In the gas pages you will find out about the connections process, how to manage a connection, charges for connections, market operations and data, how we balance the network, how we manage capacity, and more.
We own and operate the gas National Transmission Systems (NTS) in Great Britain, with day-to-day responsibility for balancing supply and demand. Our network comprises over 7,000 kilometres (4,400 miles) of high-pressure pipe and more than 600 above-ground installations.
Our role is to transport gas through the pipelines. We do not sell gas. The gas in your home or business is supplied to you by a gas supplier. Only suppliers licensed by Ofgem can sell you gas. You can find more information about who supplies gas in your area from the Energy Networks Association website.
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 NTS and liquified natural gas (LNG) importers pay for the right to land LNG at our importation terminals. Shippers also pay 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.
Your gas supplier is responsible for providing a meter and organising for your meter to be read. You should contact your gas supplier for any issues regarding your gas meter. You will find contact details for your gas supplier on your gas bill.
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:
0870 608 1524
This call will cost 7p per minute plus your phone company’s access charge.
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.
If you smell gas:
Call the 24-hour National Gas Emergency Service on 0800 111 999 immediately
Do turn off the gas at the meter unless the meter is in a cellar/basement
Don’t smoke or strike matches
Don’t turn electrical switches on or off
Do put out naked flames
Do open doors and windows
Do keep people away from the area affected.
Future of gas
Delivering the energy needs of over 23 million customers across the UK affordably, securely and sustainably is an increasingly complex task. As an industry, we all have a role to play in supporting policymakers to make the right decisions for the long and short term to ensure we continue meeting those demands. The Future of gas looks in detail at the key priorities for addressing how gas could, and should, be part of the energy mix.
UK gas transmission
We own and operate the gas national transmission system in Britain, with day-to-day responsibility for balancing supply and demand.
Gas codes are governed by the Uniform Network Code (UNC), which is administered by the Joint Office of Gas Transporters. The UNC is the hub around which the competitive gas industry revolves, comprised of 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.
