UK gas storage levels today: how many days of gas does the UK have?
At the end of gas day 10 November 2026, Britain's storage sites held 10.0 TWh, as measured by National Gas: the eight working sites are 52.7% full (28.1% of all capacity, counting Rough, which is empty). That is 4 days of Britain's average demand over the past seven days (2.6 TWh a day). At the past seven days' net storage withdrawal of 265 GWh a day, the stock would last 38 days.
These are days of cover: how long the gas in storage would last on its own. Gas from the UK North Sea, pipelines from Norway and LNG supply most of what Britain burns in winter, so neither figure is a countdown to running out.
- Storage paused. Centrica said on 23 July 2026 that gas storage operations at Rough "remained paused" after their suspension in 2025 (interim results).
- Consent until 30 April 2027. On 21 April 2026 the North Sea Transition Authority granted a production and storage consent for Rough until 30 April 2027 (NSTA). Centrica said in July that it does not currently intend to seek an extension.
- In store. National Gas's figures show no gas in store at Rough at the end of gas day 10 November 2026, against a capacity of 16.6 TWh.

Why the UK has a few days of gas and months of it at once
Days of demand divide the gas in storage by everything Britain burns in a day, as if storage were the only source. Britain holds little storage for the size of its demand, so the figure is small: a few days in winter, fewer on the coldest day. That is the arithmetic behind "two days of gas" headlines.
The runway divides the same gas by what storage actually gives up, net of refilling. On most days that is a small share of supply, because the North Sea, pipelines from Norway and LNG deliver the bulk of Britain's gas as it is used, and British stores are refilled between cold spells. So the runway is long.
Neither number means the UK is about to run out. The first says storage alone could not carry Britain for long; the second says storage is not being asked to. What would matter is a long cold spell arriving while imports are short, which is when a small store leaves less room to cover the gap.
| Measure | 10 November 2026 | Same date, 2025 | Average, 2021 to 2025 |
|---|---|---|---|
| Gas in storage | 10.0 TWh | 17.1 TWh | 22.4 TWh |
| Britain's demand, past seven days | 2.6 TWh a day | 1.7 TWh a day | 1.9 TWh a day (2022 to 2025) |
| Days of demand | 4 days | 10 days | 12 days (2022 to 2025) |
| Net storage flow, past seven days | drawing 265 GWh a day | filling 205 GWh a day | |
| Days at storage's past-week pace | 38 days | filling | |
| At the pace of the winters 2021/22 to 2025/26, 76 GWh a day | 132 days | 225 days | 295 days |
Today's stock covers 6 days fewer than it did on 10 November 2025, and 8 days fewer than the average for this date (2022 to 2025), each year at its own week's demand.
The pace of the winters 2021/22 to 2025/26: the average net storage withdrawal of those winters from 10 November to 31 March. Demand: gas taken off the national transmission system for local distribution (homes and businesses), power stations and industry, seven-day average; exports and storage injection are left out, and Northern Ireland is supplied through the Moffat export.

Days the screen refuses as corrupt at source are left as gaps. The published history starts in September 2021, so the chart shows five winters and cannot show 2017/18. Rough stored no gas from 2017 until October 2022 and paused storage again in 2025 (Centrica), which moves the winter totals.
UK gas storage capacity: the nine sites
By National Gas's figures for gas day 10 November 2026, Britain's nine storage sites can hold 35.5 TWh between them and held 10.0 TWh, 28.1% full. Rough accounts for 16.6 TWh of that capacity and held none of it (see the Rough status above). The eight working sites, every site but Rough, can hold 18.9 TWh and held 10.0 TWh, 52.7% full.
| Site | Range | In storage | Capacity | Full | Share of stock |
|---|---|---|---|---|---|
| Rough | long-range | 0.0 TWh | 16.6 TWh | 0.0% | 0% |
| Stublach | medium-range | 2.2 TWh | 4.4 TWh | 50.8% | 22% |

Live, dated to gas day 10 November 2026: the opening stock of each site for the gas day after, which is the stock at the end of 10 November 2026. Capacity is the working volume: the stock plus the space National Gas publishes as still available, which it defines as the gap between "the physical workable maximum facility volume (excluding any operating margins stocks)" and the stock. It counts Rough whether or not Rough is storing gas. Medium-range sites cycle gas in and out within weeks; Rough is Britain's only long-range store. Source: National Gas Transmission Data Portal.
Where Britain's winter gas comes from
From 1 October 2025 to 31 March 2026, 480 TWh of gas entered Britain's national transmission system. 69% came through the beach terminals, where gas from the UK North Sea and Norway lands, 25% from LNG import terminals, 5% from storage and less than 1% through the interconnectors from Belgium and the Netherlands. Storage gave a small share of that gas, which is why the runway above is long while days of demand are short.
National Gas publishes the beach terminals as one figure, so UK North Sea and Norwegian gas are not split here. Norwegian gas landing at Easington is on the Norway gas flows page, and Britain's LNG terminals are on the LNG send-out page.
| Entering the system through | Winter 2025/26 | Winter 2026/27 so far | Past seven gas days |
|---|---|---|---|
| Beach terminals: UK North Sea and Norway | 334 TWh · 69% | 72.0 TWh · 85% | 13.9 TWh · 69% |
| LNG import terminals | 121 TWh · 25% | 8.3 TWh · 10% | 4.3 TWh · 21% |
| Storage | 24.2 TWh · 5% | 4.5 TWh · 5% | 1.9 TWh · 9% |
| Interconnectors from Belgium and the Netherlands | 1.1 TWh · less than 1% | 4 GWh · less than 1% | 3 GWh · less than 1% |
| Total | 480 TWh | 84.8 TWh | 20.0 TWh |
Winter 2025/26: 1 October 2025 to 31 March 2026; so far: 1 October 2026 to 10 November 2026; past seven gas days: 4 November 2026 to 10 November 2026. Source: National Gas Transmission Data Portal: System Entry Energy, Aggregate Physical Energy, the gas physically entering the national transmission system each gas day from beach terminals, LNG importation, storage withdrawal and interconnectors. Some of it leaves again as exports to the continent and Ireland or injection into storage, so the total is more than Britain burns. Shares are rounded. A window with any day missing is not shown.
What happened to UK gas storage
Rough, off the Yorkshire coast, was Britain's largest gas store. In June 2017 Centrica stopped storing gas there after finding it could not safely return to injection. It reopened in October 2022 with space for up to 30 bcf, about a fifth of its former capacity, and doubled that to 54 bcf in 2023. Centrica paused storage in 2025 because seasonal prices no longer covered the cost, and in its July 2026 results said storage remained paused and that it does not currently intend to seek an extension of Rough's production consent, which expires in April 2027.
With Rough paused, Britain relies on medium-range stores built to cycle gas quickly rather than to hold it for a season. The government's gas security consultation of November 2025 counted eight storage facilities with 35 TWh between them, around 13 days of average winter demand. It does not name them; by our reading of National Gas's site figures, that total counts Rough.
Questions people ask about the UK's gas
How many days of gas does the UK have left?
At the end of gas day 10 November 2026, Britain's storage sites held 10.0 TWh, as measured by National Gas: the eight working sites are 52.7% full (28.1% of all capacity, counting Rough, which is empty). That is 4 days of Britain's average demand over the past seven days (2.6 TWh a day). At the past seven days' net storage withdrawal of 265 GWh a day, the stock would last 38 days. These are days of cover: how long the gas in storage would last on its own. Gas from the UK North Sea, pipelines from Norway and LNG supply most of what Britain burns in winter, so neither figure is a countdown to running out.
Does the UK only have two days of gas?
Only if storage were Britain's only source of gas, which it is not. Divide the 10.0 TWh in store at the end of gas day 10 November 2026 by last winter's highest daily demand, 4.1 TWh a day on 5 January 2026, and it covers 2 days. That arithmetic is where "two days of gas" headlines come from; a Guardian report of 8 March 2026 said Great Britain had "only two days of gas stored", with 6,999 GWh in store by National Gas's figures. Britain holds little storage for the size of its demand: the government's November 2025 consultation counted eight storage facilities with 35 TWh between them, around 13 days of average winter demand. Most of the gas it burns each day arrives the same day, from the North Sea, Norway and LNG, so a short days-of-demand figure is not a countdown to running out. The Guardian, 8 March 2026
What happened to UK gas storage (Rough)?
Rough, off the Yorkshire coast, was Britain's largest gas store. Centrica stopped storing gas there in 2017 after finding it could not safely inject and store, reopened it in October 2022 with space for up to 30 bcf, about a fifth of its former capacity, and doubled that to 54 bcf in 2023. It paused storage again in 2025 because seasonal prices no longer covered the cost, and in July 2026 said storage remained paused and that it does not currently intend to seek an extension of Rough's production consent, which expires in April 2027. National Gas's figures show Rough holding 0.0 TWh at the end of gas day 10 November 2026.
What is the UK's gas storage capacity?
By National Gas's figures for gas day 10 November 2026, Britain's nine storage sites can hold 35.5 TWh between them, 16.6 TWh of it at Rough, whose storage Centrica has paused. The government's gas security consultation of November 2025 counted eight storage facilities with 35 TWh between them, around 13 days of average winter demand. It does not name them; by our reading of National Gas's site figures, that total counts Rough. DESNZ gas security of supply consultation, November 2025
Where does the UK get its gas from in winter?
Of the gas that entered Britain's national transmission system from 1 October 2025 to 31 March 2026, 69% came through the beach terminals, where UK North Sea and Norwegian gas land together, 25% from LNG import terminals, 5% from storage and less than 1% through the interconnectors from Belgium and the Netherlands, by National Gas's figures.
Is the UK running out of gas?
No figure on this page says so. Storage is a small part of Britain's supply: on most winter days the North Sea, pipelines from Norway and LNG deliver the bulk of the gas and storage covers the peaks. At the end of gas day 10 November 2026 Britain's stores held 10.0 TWh, 4 days of the past week's demand. What would matter is a long cold spell arriving while LNG is scarce, which is when low storage leaves less room to cover the gap.
Where does this UK data come from?
National Gas Transmission's data portal, which publishes each storage site's opening stock and the gas taken off the national transmission system every gas day. Storage here is the sum of Britain's nine storage sites as National Gas measures them, not GIE AGSI+, whose UK series is an estimate over part of British storage. Demand is the gas taken off the system for homes and businesses, power stations and industry; exports and gas injected into storage are left out.

How the days are worked out
- Stock. National Gas's daily aggregated stock level, which equals the sum of the nine sites' opening stocks. The figure published for a gas day opens it, so it is dated here to the day before, the day it closes, which is how GIE AGSI+ dates stocks on the Europe and Germany pages. Some published days are corrupt at source, with blank zeros or jumps no store can make; they are refused and left out, never filled.
- Days of demand. Stock divided by Britain's average demand over the newest seven complete gas days: local distribution, power stations and industry, without exports or storage injection. National Gas posts a day's figures as zero until they settle, so a day counts only when all three parts are in, and a week that ends more than two days before the stock's gas day is not shown.
- Past-week pace. Stock divided by the fall in storage over the past seven gas days, per day, shown only while storage is being drawn down within a year.
- The pace of the winters 2021/22 to 2025/26. The average net withdrawal of those winters over the part of the withdrawal season still ahead of this date. National Gas's published history begins in 2021, so the pace reaches back no further than the 2021/22 winter.
No prices are used or shown. GIE AGSI+ carries an estimated UK series over part of British storage, which this page does not use.
