Energy bills to rise again from January but spring falls to come, research firm Cornwall Insight forecasts

Energy bills are to rise again next year, according to a respected forecaster.

Costs from January to March are projected to rise another 1% to £1,736 a year for the average user, according to research firm Cornwall Insight.

The energy price cap, which sets a limit on how much companies can charge per unit of electricity, is also expected to rise, costing typical households an extra £19 a year.

It’s a further increase after energy costs rose 10% from October.

After the latest hike, there were hopes of a fall in the new year, but volatile wholesale gas and electricity markets are still above historic average costs.

Prices have gone up due to supply concerns arising from Russia‘s war in Ukraine, and maintenance of Norwegian gas infrastructure.

But spring is expected to herald a reduction as is October 2025, Cornwall Insight said.

Every three months energy regulator Ofgem revises the cap based on wholesale costs.

The official January price cap announcement will be made on Friday.

It comes as millions of pensioners lost their automatic winter fuel allowance payment after the government means-tested the benefit.

Meanwhile, Cornwall Insight’s principal consultant Dr Craig Lowrey warned “millions” of households won’t heat their homes to “recommended temperatures, risking serious health consequences” with bills on the rise.

“With it being widely accepted that high prices are here to stay, we need to see action,” he said, suggesting options like cheaper rates for low-income homes, benefit restructuring, or other targeted support for the vulnerable “must be seriously considered”.

The energy price cap system is being reviewed by Ofgem with possible changes to the standing charge coming over the next year.
