UK faces highest winter energy bills as gas storage hits decade low

Wholesale gas prices across Europe climbed to €97 per megawatt-hour on Monday, marking the highest level recorded since 2022. The surge reflects growing anxiety over winter supply reliability and shifting geopolitical dynamics in the Middle East. Traders responded to falling temperatures across the continent by pricing in increased demand for heating.

The price jump coincides with reports that the United States and Israel have prepared plans for renewed military strikes against Iran following the recent U.S. midterm elections. These developments pushed oil prices to a peak of $117 per barrel on Friday. By Monday, the international Brent crude benchmark had retreated by approximately 2%, yet it remained above $114 per barrel.

Supply concerns are compounded by low storage levels entering the winter season. European gas reserves stand at approximately 75% capacity, the lowest point in more than a decade. This deficit stems from a slowdown in exports from Qatar and higher summer consumption driven by the need for refrigeration and cooling. The seasonal average for storage levels at this time of year is closer to 80%.

The United Kingdom faces particular pressure due to its reliance on imported gas. British energy regulators stated that the country is expected to incur some of the highest energy costs in Europe this winter. The UK possesses some of the smallest gas storage facilities on the continent, a legacy of decades of relying on North Sea production. According to the Office for National Statistics, Britain paid a record £4 billion for power imports in the year ending in August, with half of that sum allocated to electricity from France.

The UK also made near-record payments over the past year to operate gas plants while wind and solar farms were compensated to reduce output due to grid bottlenecks. British households are now facing rising energy bills, with forecasts indicating a 16% increase in January. The typical annual dual fuel bill is projected to reach the equivalent of roughly £2,000.

Market reactions on Monday showed modest gains in equities despite the energy cost pressures. The Stoxx Europe 600 index, which tracks the largest companies in Europe, rose by 0.3% in early trading. The UK’s FTSE 100 blue-chip index increased by 0.4%, aided by the slight drop in oil prices from its Friday peak.
