Millions of UK households may avoid further energy bill increases this winter, thanks to improving market conditions and geopolitical developments. Recent fears that the ongoing conflict involving Iran could disrupt liquefied natural gas (LNG) supplies through the Strait of Hormuz—a critical global energy route—caused wholesale gas prices to surge, prompting Ofgem to set a 13% increase in the energy price cap from July to October 2026.
However, optimism is growing following reports of a potential US-Iran peace agreement and expectations that shipping through the Strait of Hormuz will soon return to normal. This positive shift could see the Ofgem price cap decrease in October, easing the financial pressure on millions of British households.
Sanjay Raja, chief UK economist at Deutsche Bank, noted, “It looks increasingly likely that the Ofgem Price Cap could be lower, rather than higher, in October 2026, offering much-needed relief to UK families and businesses.”

This hopeful outlook coincides with inflation remaining steady at 2.8% in May, weaker than many had predicted, mainly driven by a drop in wholesale energy prices. European benchmark gas prices fell below €42 per megawatt hour, down more than 9%, after news of peace talks and plans to reopen the Strait of Hormuz. This narrow shipping route accounts for about 20% of the world’s LNG supplies, underscoring its strategic importance.
Earlier this year, disruptions through this corridor caused European gas prices to spike by 31%, with the region’s overall gas costs rising nearly 50%. The recent price decline suggests traders are increasingly confident that the worst supply disruptions have been avoided.
Crude oil prices have also fallen sharply, currently about 10% below last month’s assumptions. This decrease should ease inflationary pressures and help slow the rise in household energy costs as the year progresses.
For consumers, while an energy bill increase from July is largely unavoidable, fears of another bill hike this winter are easing. Should the ceasefire hold and LNG shipments stabilize, the October price cap could bring a reduction rather than a rise. For an average household, this could mean annual savings ranging from £37 (2% cut) to as much as £92 (5% cut).
Despite this, analysts caution that energy bills are unlikely to return to pre-crisis levels soon. Wholesale gas prices remain approximately 25% higher than last year due to ongoing global supply concerns and damage to export infrastructure in Qatar.
Looking ahead, some optimistic forecasts suggest Europe might experience significantly lower wholesale gas prices over the next decade. If new LNG export projects come online and gas demand diminishes with the transition to cleaner energy and electrification, wholesale prices could fall to about €25 per megawatt hour—roughly half the current level amid the Iran-related crisis.
While this scenario is just one possibility amid various geopolitical risks, it highlights the potential for more stable and affordable energy costs for consumers in the long term.
