The Great Britain Gas System
See the latest supply, demand and linepack on Great Britain’s high-pressure gas network, plus the monthly breakdown of where UK gas came from.
What the gas transmission system is
Gas arrives from British production, Norway, liquefied natural gas terminals and continental pipelines. The transmission system supplies local networks, industry, power stations and exports. It does not show gas going to an individual home.
The current snapshot
These are near-live flow rates rather than daily totals.

How to read these figures
Keep these distinctions in mind.
Rates, not daily totals. A value in mcm/day is the rate at that moment expressed on a per-day basis. It is not the volume already used that day.
Transmission system only. These flows do not identify the gas supplied to a particular home, tariff or local network.
Linepack is a stock. It is the amount held in the transmission network, measured in mcm, rather than a flow rate.
Where Britain’s gas comes from
The monthly origin breakdown separates four routes.
- British production: gas from fields in UK waters.
- Norwegian pipelines: direct undersea imports.
- Liquefied natural gas: shipped to coastal terminals and converted back into gas.
- Continental interconnectors: pipelines that can move gas between Britain and Europe.

Where the gas came from
A closed month from the official statistics, not the live flow above. The United Kingdom produced 25,879 GWh of gas and imported 27,716 GWh of it, which together are the whole of supply.
These are United Kingdom figures, including Northern Ireland. The live section higher up this page is the Great Britain national transmission system, which does not reach Northern Ireland — so the two cover different ground as well as different periods, and neither is a check on the other.

Every import route that delivered
Shares are of total imports rather than of all supply. A further 25 published origins delivered nothing this month, which the statistics record as zero rather than leaving blank.

Biomethane: 489 GWh of gas entered the grid from anaerobic digestion rather than from a well. DESNZ reports it separately from gross production and imports.

The sectors above do not add up to published demand on their own; the difference is the last row, and it is shown rather than absorbed.
Supply and demand are published monthly from 1996; the breakdown by route and country begins later, in 2000, so the two series do not cover the same span.

Linepack: the cushion in the pipes
Linepack is the gas held in the pressurised transmission pipes. It acts as a buffer between steady supply and demand that rises in the morning and evening. Falling linepack means demand is exceeding supply at that moment.
Why gas sets the electricity price
Gas-fired power stations often set the wholesale electricity price because they are the last generation needed to meet demand. A change in gas prices can therefore affect both gas and electricity bills.
The effect is strongest during cold, still weather, when demand is high and wind output is low. Current generation is on the live electricity page.
What this means for your bill
Wholesale movements reach standard variable tariffs through the price cap that is set every three months. Fixed-tariff rates do not change during their term.
If you want to know what any of this costs at your meter, our typical household energy use page has the consumption side, and the energy bill calculator turns it into money.
Frequently asked questions
Where does the UK get its gas from?
Four routes, in roughly descending order of size: gas produced from British waters, pipeline imports from Norway, liquefied natural gas shipped in and regasified at coastal terminals, and pipeline links to continental Europe. The mix shifts with price and season, and the supply-by-origin table on this page shows how it is split at the moment the reading was taken.
What does mcm/day mean?
Million cubic metres per day. It is a rate, not a running total: a figure of 200 mcm/day means gas is moving at a pace that would deliver 200 million cubic metres over 24 hours if it held steady, not that 200 million have already flowed today.
What is linepack?
The gas held inside the transmission pipes themselves. The network is pressurised, so it stores a usable cushion of gas that absorbs the mismatch between supply arriving steadily and demand that peaks morning and evening. Linepack is a stock measured in mcm, not a flow, which is why it is reported separately.
Why does the gas price affect my electricity bill?
Because gas-fired power stations are usually the last generation needed to meet demand, and in the Great Britain wholesale market the most expensive plant required sets the price paid to all of them. When gas gets more expensive, the electricity price follows, even for the electricity generated by wind or nuclear.
Does this page show the gas going to my house?
No. These are flows on the national transmission system — the high-pressure pipes that move gas around the country. Your home is supplied from a local distribution network downstream of it, and nothing here identifies gas going to a particular property, supplier or tariff.
