UK gas reserves at 6,700 GWh—below two days’ supply—due to Middle East tensions and reduced output, sparking price spikes despite secure supply.

The UK has less than two days of natural gas storage, with reserves at about 6,700 gigawatt hours—down from 18,000 GWh in 2025—due to Middle East tensions, tanker diversions, and Iran’s closure of the Strait of Hormuz. Gas prices have surged, with UK month-ahead prices reaching 137p per therm, exceeding European benchmarks. Despite low reserves, officials say supply remains secure thanks to diverse imports from Norway, the North Sea, and LNG, along with interconnectors and flexible storage. Experts warn the UK’s limited storage makes it vulnerable to global shocks, urging investment in new facilities and floating storage to improve resilience amid declining North Sea output and rising demand.
