Ofgem’s energy price cap will fall this weekend, but there are fears the average household could still end up paying more for energy this winter than last year.

The energy regulator announced in August that the cap on a unit of gas and electricity would reduce the average bill from £2,074 to £1,923 for the three months from October 1 in England, Wales and Scotland.

The cap does not set an upper limit on actual bills, and households will pay more or less depending on how much energy they use.

Despite the reduction, the new cap will still be 50% higher than pre-crisis levels, and the Government is yet to announce any financial support along the lines of last year, when the Energy Price Guarantee limited average bills to £2,500 per year and each household received a further £400 over six months to offset the soaring costs.

These measures brought the average monthly cost of energy down to £141 but this year, unless further support is announced, average costs from October to December 2023 will rise to £160.

Bill payers are advised to submit meter readings ahead of October 1 to ensure their supplier can accurately bill them for energy used before and after the price cap drop.

On announcing the latest cap, Ofgem chief executive Jonathan Brearley said that now energy prices were easing, the regulator had allowed suppliers to earn a little more money off their customers.

He said: “This means there should be no excuses for suppliers not to be doing all they can to support their customers this winter, and to reinforce this we’ll be introducing a consumer code of conduct which we will look to have in place by winter.”

Mr Brearley is one of many to question the effectiveness of the price cap and point towards the benefits of a social tariff, which would offer cheaper gas and electricity to those most in need.

Without that, experts expect that average energy bills will remain at around £2,000 for vulnerable households for years to come.

Simon Francis, coordinator of the End Fuel Poverty Coalition, which is part of the Warm This Winter campaign, said: “From October 1, all households in every part of the country will pay more on energy standing charges, more into the profits of energy firms and many are more in debt to their suppliers.

“Average energy bills are still almost double what they were three years ago and Government help for households, which was available last winter, has been axed. This means this winter will feel worse for many households.

“If Members of Parliament on the House of Commons Energy Security Committee can see problems households will face, why can’t the Government? The MPs’ recent report on tackling the energy bills crisis sets out sensible recommendations to help vulnerable households and ministers need to implement these ideas immediately.”
