# UK Gas Storage Crisis: Why Britain Has Just 2% of Europe's Capacity and What It Means for Energy Security

> The UK has the lowest gas storage capacity in Europe at just 2 billion cubic metres, enough for 4-5 days of winter demand, compared to Germany's 90-day supply. This leaves Britain uniquely exposed to price spikes and supply shocks, but expanding storage faces economic and political barriers.

## Key takeaways

- The UK has just 2 billion cubic metres of gas storage capacity, equivalent to 4-5 days of winter demand, the lowest in Europe and down from 5 billion cubic metres in 2010
- Germany has 24 billion cubic metres (90 days), France 13 billion (45 days), and Italy 18 billion (60 days), giving them far greater resilience to supply shocks and price volatility
- The UK closed its largest storage facility, Rough, in 2017 due to safety concerns, and no major new storage has been built since, leaving the country reliant on imports and just-in-time supply
- Low storage made the UK more vulnerable during the 2021-22 gas crisis, contributing to sharper price spikes and higher bills than countries with larger reserves
- The government announced plans in 2024 to double storage capacity by 2030, but projects face high costs, planning delays and uncertain economics, and no new facilities have reached construction stage

## Context: the storage gap and its consequences

Gas storage is the unglamorous backbone of energy security. It allows countries to stockpile gas during summer when demand is low and prices are cheap, then draw it down in winter when demand surges and prices spike. It provides a buffer against supply disruptions—whether from pipeline failures, geopolitical shocks or extreme weather—and smooths price volatility by reducing the need to buy gas at spot prices during crises.

The UK has less gas storage than any major European economy, and the gap is stark. As of January 2026, the UK has **2 billion cubic metres (bcm)** of working gas storage capacity, equivalent to just 4-5 days of winter demand. Germany has 24 bcm (90 days), France 13 bcm (45 days), Italy 18 bcm (60 days), and even the Netherlands, a much smaller country, has 13 bcm (50 days). The UK's storage capacity has fallen sharply over the past 15 years, from 5 bcm in 2010 to 2 bcm today, due to the closure of the Rough facility in 2017 and the lack of investment in new storage.

This vulnerability was exposed brutally during the 2021-22 gas crisis. When wholesale gas prices surged from 50p per therm in early 2021 to £6.50 in August 2022, the UK had no reserves to draw on and was forced to buy gas at spot prices throughout the crisis. Countries with large storage were able to fill their reserves when prices were low and draw them down when prices spiked, dampening the impact on consumers. The UK, by contrast, experienced some of the sharpest price rises in Europe, contributing to the £4,279 energy price cap peak and the £40 billion cost of government support.

The government has acknowledged the problem. The 2022 British Energy Security Strategy committed to doubling gas storage capacity by 2030, and in 2024 it launched a consultation on policy support for new storage projects. But progress has been slow. No major new storage facilities have been built, and the economics remain challenging: storage is expensive to build and operate, and in a liberalised market it is hard to make a profit unless there are large seasonal price swings. The UK is caught between the need for energy security and the reluctance to subsidise infrastructure that may not pay for itself.

## The data: how the UK compares

As of January 2026, the UK has **2 bcm** of working gas storage capacity across 8 facilities, according to Gas Infrastructure Europe's storage database. The largest is Rough (0.7 bcm), a partially reopened offshore facility in the North Sea. The rest are small onshore salt cavern sites: Holford (0.4 bcm), Humbly Grove (0.3 bcm), Hornsea (0.2 bcm), Aldbrough (0.2 bcm), Stublach (0.15 bcm), and two smaller sites totalling 0.05 bcm.

This 2 bcm represents **4-5 days** of winter gas demand. The UK uses around 400-450 million cubic metres (mcm) of gas per day in winter, so storage can cover less than a week of consumption. In summer, when demand falls to 150-200 mcm per day, storage covers 10-13 days, but summer is when storage is least needed.

Compare this to the rest of Europe:

| Country | Storage capacity (bcm) | Days of winter demand |
|---|---|---|
| Germany | 24.0 | 90 |
| Italy | 18.0 | 60 |
| France | 13.0 | 45 |
| Netherlands | 13.0 | 50 |
| Austria | 9.0 | 100 |
| UK | 2.0 | 4-5 |

Germany's 24 bcm is twelve times the UK's capacity, despite having a population only 20% larger. Italy, with a similar population to the UK, has nine times the storage. Even small countries like Austria have far more storage relative to demand.

The UK's storage capacity has fallen sharply over time. In 2010, the UK had **5 bcm** of capacity, with Rough accounting for 3.3 bcm. When Rough closed in 2017, capacity dropped to 1.7 bcm. Rough partially reopened in 2022 with reduced capacity (0.7 bcm), bringing the total to 2 bcm, but this is still 60% below the 2010 level.

## What's changing: the Rough closure and the failure to replace it

### The rise and fall of Rough

Rough was the UK's strategic gas reserve. Located 18 miles off the Yorkshire coast, it was a depleted gas field converted to storage in 1985, with a capacity of 3.3 bcm—70% of UK total. It operated as a seasonal storage facility: gas was injected in summer and withdrawn in winter, smoothing supply and prices. At its peak, Rough could meet 10% of UK winter gas demand.

But Rough was ageing. By the 2010s, the offshore infrastructure—wells, pipelines, platforms—was over 30 years old and showing signs of wear. In 2017, safety inspections by the Health and Safety Executive found that the facility could not be operated safely without major investment. Centrica, the owner, faced a choice: spend hundreds of millions on refurbishment or close the facility. With gas prices low and storage margins thin, Centrica chose closure.

The decision was economically rational but strategically disastrous. Overnight, the UK lost 70% of its gas storage capacity, leaving it uniquely exposed to supply shocks. The government did not intervene—there was no legal obligation to maintain storage, and the prevailing view was that the market would provide alternatives. It did not.

Rough partially reopened in 2022, after the gas crisis made storage economics more attractive. Centrica invested in limited refurbishment and brought 0.7 bcm of capacity back online, but the facility remains far below its original size and is expected to close permanently by 2030 as the infrastructure deteriorates further.

### Why no new storage was built

The obvious question is why, in the five years between Rough's closure in 2017 and the 2021-22 gas crisis, no new storage was built. The answer is economics and policy.

Gas storage is expensive. Building a new salt cavern storage facility costs £200-500 million for 0.5-1 bcm of capacity, and offshore storage is even more expensive. Operating costs are high, and revenue depends on the seasonal price spread—the difference between summer and winter gas prices. In the 2010s, this spread was narrow (5-10p per therm), making storage unprofitable. Developers could not justify the investment without subsidies or regulatory mandates, and the government provided neither.

The UK's liberalised energy market, which relies on competition and market signals rather than state planning, assumes that if storage is needed, the market will provide it. But storage is a public good—it benefits everyone by stabilising prices and enhancing security, but the benefits are diffuse and hard to monetise. This is a classic market failure, and it requires government intervention to fix.

Several storage projects were proposed in the late 2010s and early 2020s, including expansions of existing salt cavern sites and new offshore facilities, but none progressed to construction. Planning delays, uncertain economics and lack of policy support killed them. The government's 2024 consultation on storage support mechanisms—such as cap-and-floor regulation (guaranteeing minimum revenues) or strategic reserve mandates—has not yet led to concrete action.

## What it means: the cost of low storage

The UK's low storage capacity has three main consequences: higher price volatility, greater exposure to supply shocks, and higher costs during crises.

### Price volatility

Without storage, the UK is a price taker in the global gas market. When demand is high or supply is tight, the UK must buy gas at spot prices, which can spike sharply. Countries with large storage can draw down reserves and avoid buying at peak prices, dampening volatility. During the 2021-22 crisis, UK gas prices rose faster and higher than in Germany or France, partly because the UK had no reserves to cushion the shock.

### Supply shock exposure

Storage provides resilience against supply disruptions. If a pipeline fails, a cold snap hits, or a geopolitical event cuts supply, countries with storage can draw down reserves to cover the gap. The UK, with just 4-5 days of storage, has almost no buffer. A major supply disruption—such as a failure of the Norway pipelines, which provide 60% of UK gas imports—would leave the UK scrambling to buy LNG on the global market, likely at extreme prices.

### Crisis costs

Low storage made the 2021-22 crisis more expensive for the UK. The government spent £40 billion on the Energy Price Guarantee to cap bills, and consumers still faced a near-quadrupling of the price cap. Countries with large storage, while not immune, faced smaller price rises and lower government support costs. The UK's lack of storage effectively transferred billions from taxpayers and consumers to global gas suppliers.

## What to watch next

Watch the government's response to the 2024 storage consultation. If it introduces cap-and-floor regulation or strategic reserve mandates, it could unlock investment in new storage. If it relies on market signals alone, storage capacity will remain low and the UK will remain vulnerable.

Watch the Rough facility. Centrica has said it will close permanently by 2030, which would cut UK storage by 35% unless new capacity is built. If Rough closes and no replacement emerges, the UK's storage position will worsen.

Watch the economics of storage. If seasonal gas price spreads widen—due to increased reliance on renewables (which makes winter demand more gas-dependent) or geopolitical instability—storage becomes more profitable and investment may follow. If spreads remain narrow, storage will struggle to attract private capital without subsidies.

The UK's gas storage crisis is a policy failure, not a technical one. The infrastructure can be built, the sites exist, and the need is clear. What's missing is political will and a recognition that energy security is a public good that requires public investment. Until that changes, the UK will remain uniquely exposed to the next gas crisis—and there will be a next one.

## Frequently asked questions

### Why does the UK have so little gas storage compared to other countries?

The UK historically relied on North Sea gas production and flexible import infrastructure (pipelines from Norway and LNG terminals) rather than storage. The logic was that storage is expensive and the UK could buy gas when needed from global markets. This worked when gas was cheap and abundant, but the 2021-22 crisis exposed the vulnerability: without storage, the UK must buy gas at spot prices during supply crunches, leading to sharper price spikes. The closure of Rough, the UK's largest storage facility, in 2017 due to safety issues cut capacity by 70% and no replacement was built.

### What happened to Rough and why wasn't it replaced?

Rough was a depleted offshore gas field converted to storage, with 3.3 billion cubic metres capacity—70% of UK total. It was closed in 2017 after safety inspections found the ageing infrastructure could not be operated safely without major investment. The owner, Centrica, decided closure was more economical than a costly refurbishment. Rough partially reopened in 2022 with reduced capacity (0.7 billion cubic metres) to help with the energy crisis, but it remains far below its original size. No new large-scale storage was built to replace it because low gas prices in the 2010s made storage unprofitable.

### Would more storage lower energy bills?

Not directly, but it would reduce price volatility and provide insurance against supply shocks. Storage allows the UK to buy gas when it is cheap (summer) and use it when it is expensive (winter), smoothing prices. During the 2021-22 crisis, countries with large storage (Germany, France) were able to draw down reserves and avoid some of the worst price spikes. The UK, with minimal storage, had to buy gas at peak prices throughout the crisis. More storage would not eliminate price rises, but it would dampen them and reduce the risk of extreme spikes.
