Energy Bills to Hit Three-Year High as Ofgem Confirms 4% Autumn Rise

Household energy bills are to climb to their highest level in three years this autumn, after the regulator Ofgem announced a 4% increase in the price cap, driven by a surge in wholesale gas costs linked to the conflict in Iran. From 1 October, a household using a typical amount of gas and electricity will pay £60 more per year, bringing the average annual bill to £1,723. More than a third of households, however, are on fixed tariffs and will be shielded from the immediate increase.

The Prime Minister, Andy Burnham, acknowledged the rise would be "difficult" for families, but pointed to the government’s planned cut to VAT on electricity bills, which he said would save the average household £45 from the same date. He insisted the government would "continue to look... at how we get energy prices down in the long term." Alongside the VAT reduction, the government has highlighted the warm homes discount, which will take £150 off bills for six million low-income households this winter. Yet these measures have done little to quell a growing political storm, with the opposition arguing that Labour is not doing enough to address the persistent cost-of-living pressures.

Shadow energy secretary Claire Coutinho said the government must "put cheap energy first," claiming that while it had promised to cut bills by £300, they had "gone up by nearly £400 instead." The Liberal Democrat spokesperson for energy, Pippa Heylings, echoed the criticism, urging Mr Burnham to "wake up to the scale of the challenge." In a further intervention, former Prime Minister Gordon Brown proposed a novel solution: a "machine gaming tax" to raise funds for struggling households. He also suggested the government should examine the introduction of a social tariff for energy, a move he believed the Prime Minister would be open to.

The price rise, described by Ofgem’s director general for markets, Neil Kenward, as technically 3.6% before rounding, has been driven by international wholesale costs, which now constitute just over a third of a typical dual-fuel bill. The average price of gas has been 61% higher over the past three months compared to late 2025, according to Energy UK, the suppliers' trade body. Households are still paying roughly 70% more on average than before Russia's full-scale invasion of Ukraine precipitated the energy crisis in 2022, a stark illustration of the conflict's enduring economic fallout.

Mr Kenward sought to offer a sliver of consolation, noting that while gas bills were rising by 8%, electricity bills were actually falling slightly due to the government's VAT cut. He argued this widening gap between the cost of gas and electricity made it cheaper for households to transition to heat pumps. He also advised consumers that "savings are available by choosing a fixed tariff, which are available at £100 or more below the October price cap."

The prospect of further pain on the horizon is adding to the anxiety. Analysts at the consultancy Cornwall Insight have forecast that domestic energy prices may rise by an additional 9% in the new year, bringing renewed concern during the coldest months. This warning comes as suppliers report that energy debt has rocketed to an estimated collective total of £6bn, with expectations it will rise to £7bn by the end of the year. Energy UK has renewed its call for a flexible discounted tariff for the most vulnerable, funded by taxation, a position supported by debt charities.

For families like Dana Lazarevic, a single mother and lecturer from Leeds, the rising costs mean careful planning. She told the BBC she coordinates her washing times to make use of cheaper off-peak periods. "When winter comes and the cold bites, you need to put on the heating and need to have the money to pay for it," she said. Vanessa Northam, director at the debt charity StepChange, reported that those seeking help now often carry an average energy debt of £2,600, on top of other financial commitments. Her advice for those who may be just managing is to take stock of their finances, check bills for accuracy, and, crucially, to tell their supplier if they think they are going to struggle, as support schemes are available.
