LONDON / RankWire.AI / – British households face another sharp rise in energy costs this winter as forecasts point to higher regulated bills from January. Energy UK said the average of current projections puts the January 2027 price cap near £2,077. The current cap stands at £1,723 for a typical dual-fuel household paying by direct debit. Ofgem introduced that level on October 1 after a 4% quarterly increase. Around 22 million households remain covered by the default-tariff cap across England, Scotland and Wales.
Energy UK said the projected January level would bring household costs close to those seen during the 2022 energy crisis. The comparison reflects changes in typical energy use since that period. A £2,500 annual bill in 2022 terms equals about £2,100 under current consumption assumptions. The government set the Energy Price Guarantee at £2,500 for a typical household during winter 2022/23. Households also received £400 through a separate support scheme during that period.
Cornwall Insight has issued a similar warning for the start of 2027. It expects the Ofgem price cap to rise to £1,999 for a typical dual-fuel household in January. That would mark a 16% increase from the current level and add £276 to annual costs. The increase would be the largest quarterly rise since January 2023. Wholesale gas prices remain a major driver of household energy bills. European gas storage levels also entered September below their long-term average.
Energy debt adds pressure on households
Household energy debt has climbed alongside higher living costs. Energy UK estimated domestic energy debt reached a record £6 billion in the first half of 2026. More than three million customers were in debt or arrears, with average balances near £1,800. Ofgem separately reported £5.02 billion in combined domestic debt and arrears at the end of the second quarter. That total was 13% higher than a year earlier and continued the increase recorded since 2023.
The October price cap already added £60 a year for a typical dual-fuel household paying by direct debit. Average electricity prices now stand at 26.32 pence per kilowatt hour. Gas averages 7.97 pence per kilowatt hour. Electricity standing charges average 54.83 pence a day, while gas charges average 29.68 pence. Actual bills vary according to energy use, region, meter type and payment method. About 11 million households on fixed tariffs do not face the current default-tariff increase.
Electricity VAT cut softens part of increase
The government removed VAT from household electricity bills on October 1, with the change running through March 31, 2027. Gas bills continue to carry 5% VAT. The electricity tax cut reduces costs that would otherwise appear in household bills this winter. Wholesale energy costs still make up a major part of the price cap calculation. The cap also includes network charges, supplier operating costs and regulated allowances. Ofgem reviews the cap every three months using updated underlying cost data.
Debt levels remain another key measure of pressure in the UK energy market. Industry estimates indicate domestic energy debt could reach £7 billion by the end of 2026. Ofgem data show average arrears without repayment plans reached £1,872 for electricity and £1,613 for gas during the second quarter. Nearly 1.19 million electricity customers had arrears without repayment arrangements. About 955,000 gas customers were in the same position. Higher regulated prices and record debt now define the winter affordability challenge for millions of households.
