Households facing expected £100 rise to energy price cap from April

Households have learnt they are facing a £100 hike to energy bills in April on the eve of a 2% increase to Ofgem’s price cap taking effect.

Rising charges to operate and maintain Great Britain’s electricity and gas networks, alongside a slight increase in a levy to support the next generation of nuclear power stations, are forecast to push the price cap to approximately £100 higher in April compared with January, experts at Cornwall Insight said.

The news comes on the eve of a 2% increase to Ofgem’s price cap taking effect, pushing energy bills for the average household paying by direct debit for gas and electricity from the current £1,720 to £1,755 per year.

Cornwall Insight has predicted that the price cap will fall in January back to £1,725 a year for a typical dual fuel household, but has now suggested any relief will be short-lived.

Calls for targeted social tariffs and other support measures are expected to grow as households face ongoing pressure on energy bills.

Craig Lowrey, principal consultant at Cornwall Insight, said: “A dip in bills this January might come as a relief for households, but we shouldn’t mistake this as the start of a trend toward cheaper energy.

“The reduction we are forecasting is being driven by relatively small shifts in the wholesale market. At the same time, new charges like those to support nuclear development are starting to appear on bills, and that’s a sign of things to come.

“Any fall in January would represent a pause rather than a permanent drop. By spring, costs are expected to rise again as network charges and policy costs increase.

“It’s a reminder that while wholesale prices may be softening, the costs of running and upgrading Britain’s energy system are moving in the opposite direction.

“Ultimately, adjusting bills, whether through lower standing charge tariffs or redistributing costs, won’t deliver meaningful savings. The only route to genuinely lower energy costs is a move toward secure, sustainable energy.

“That transition comes with an upfront price tag, and there needs to be an honest discussion about the costs, and what they mean for customers.

“The real challenge is how we support households through the shift, with targeted social tariffs playing a vital role. One thing for sure is that the price cap alone cannot solve this crisis.”

Will Owen, energy spokesman at Uswitch, said: “This prediction of higher energy prices in 2026 on the eve of another increase in the price cap is a bitter pill to swallow for hard-working households.

“Suggestions of a small dip in the January price cap are quickly eclipsed by expectations of a £100 hike in April, adding up to more bad news for household bills.

“The predicted rise is driven by the increasing costs of making our energy grid fit for the future, and these charges are being passed on to bill-payers.

“If you’re on a standard variable tariff, you can beat these expected rises and save on bills by switching to a well-priced fixed deal now.

“There are currently 26 fixed deals priced below the October price cap, with savings of around £234 for the average household.”

A spokesperson for the Department for Energy Security and Net Zero said: “The only way to bring down energy bills for good is with the government’s clean energy superpower mission.

“Our energy infrastructure was designed decades ago and has suffered from years of underinvestment in recent years – if we don’t take action British families will be stuck on volatile and unpredictable fossil fuel markets that saw energy bills go through the roof when Russia invaded Ukraine.

“Any commentary on bills is speculative until Ofgem confirms the level of future price caps.”
