Energy bill forecasts are indicating that UK households may face significant increases in the coming months, with some predictions suggesting rises exceeding £400. According to the energy regulator Ofgem, the average household energy bill will rise to £1,723 from October, marking a £60 increase, or about four per cent, compared to the current rate. However, an independent forecast from EDF Energy suggests a much higher 30 per cent increase, pushing the average bill to £2,165, while Bloomberg Economics estimates a 25 per cent rise to £2,150 for the January to March period. These figures would mark the highest energy bill levels since June 2023. Tensions between the US and Iran have contributed to rising fuel prices, with ceasefire talks breaking down in July. This has added pressure to global fuel markets, especially after the effective closure of the Strait of Hormuz, a crucial oil shipping route, which began in February. Energy consultancy Cornwall Insight predicted in August that the energy price cap for January would be set at £1,872, an increase of £149 from the current level. However, wholesale energy prices have risen further since then, and a new forecast from a leading energy firm is expected later this month. The energy price cap is the maximum amount energy suppliers can charge for each unit of energy for households on standard variable tariffs, which cover most UK homes. The cap is presented as an annual bill for the average home, but it is not the maximum possible yearly cost. The regulator regularly updates its methodology to reflect changes in average energy usage. Under the previous calculation method, the EDF forecast would equate to £2,425 per year, a level close to the £2,500 threshold at which the government intervened in 2022 to protect households from the price shock caused by Russia’s invasion of Ukraine. Prime Minister Andy Burnham’s early policy move was to introduce a temporary VAT cut on energy bills, saving the average household £45 per year starting in October. This followed an earlier initiative from former Chancellor Rachel Reeves in 2025 aimed at reducing the average energy bill by £150 by scrapping two energy efficiency schemes. A significant rise of over £200 in January could effectively negate these measures, though energy bills would still be lower than they would have been without the policies. The increase could also worsen the already difficult economic situation for the government, potentially pushing the headline inflation rate above 4 per cent. The UK’s Consumer Price Index (CPI) rose to 3.1 per cent in August, largely driven by rising fuel costs. Chancellor John Healey is set to announce his first Budget as chancellor at the end of October, where further action on energy bills and the cost of living is expected. A government spokesperson stated that the Chancellor is focused on providing relief to families and businesses, noting that VAT has been removed from electricity bills and that electricity costs for over 10,000 manufacturing businesses are being reduced by up to 25 per cent through the British Industrial Competitiveness Scheme.
