Millions of UK households may avoid further energy bill increases this winter, thanks to a promising shift in the international gas market. Just weeks ago, rising tensions with Iran and threats to gas shipments through the Strait of Hormuz had raised fears of soaring energy costs. This caused wholesale gas prices to spike, contributing to Ofgem’s decision to increase the energy price cap by 13% from July to October 2026.
However, recent developments have brightened the outlook. News of a potential US-Iran peace agreement has raised expectations that shipping through the critical Strait of Hormuz — a vital route for roughly 20% of the world’s liquefied natural gas (LNG) supplies — will normalize soon. This improvement has triggered a sharp fall in European benchmark gas prices, dropping below €42 per megawatt hour, down by more than 9%.
Sanjay Raja, Chief UK Economist at Deutsche Bank, commented, “It’s increasingly likely that the October 2026 Ofgem price cap could be lower, easing financial pressure on households and businesses across the UK.”

Inflation held steady at 2.8% in May, surprising some economists who expected a rise. The easing in wholesale energy costs plays a significant role in this moderation. Alongside gas prices, oil prices have also declined by around 10% compared to last month’s forecasts, which could further help reduce inflation and household energy expenses later this year.
Despite the unavoidable increase in energy bills from July, fears of another rise this winter have diminished. If the ceasefire remains stable and gas exports through the Strait of Hormuz return to previous levels, UK households could see a decrease in the October energy price cap instead of an increase, potentially saving as much as £92 annually with a 5% reduction.
Currently, the price cap from July stands at approximately £1,849 per year for a typical household. A modest 2% drop in October would save about £37 annually, while a 5% decline could deliver £92 in savings.
It’s important to note that even with a potential October cut, energy bills will likely remain higher than in previous winters since wholesale gas prices are still around 25% above their levels from 12 months ago. This is due to ongoing concerns about global supply disruptions and damage to export infrastructure in Qatar.
Looking further ahead, there is cautious optimism. Research by the Centre for the Study of Democracy and the Regional Centre for Energy Policy Research suggests that increased global LNG exports combined with declining gas demand in Europe—driven by cleaner energy adoption—could halve wholesale gas prices over the next decade to about €25 per megawatt hour.
While this scenario isn’t guaranteed and depends on geopolitical stability and market conditions, it does offer hope for more affordable energy costs in the long term.
