Household energy bills in Great Britain saw a 7% reduction starting April 1, 2026, as a new price cap took effect and calculation methods were revised. However, this relief is tempered by rising network maintenance costs and the looming threat of a significant increase this summer due to escalating global oil prices.
The annual bill for a typical dual-fuel household paying by direct debit is now £1,641, a decrease of £117 from the previous quarter. Yet, prices remain approximately one-third higher than pre-Ukraine war levels.
The energy price cap, set by regulator Ofgem every three months, limits the maximum charge per unit of gas and electricity for around 19 million households on standard variable tariffs in England, Wales, and Scotland. From April to June, gas is capped at 5.74p per kWh and electricity at 24.67p per kWh.
Concerns are mounting for the next adjustment period beginning July 1. The recent surge in oil prices, linked to the US-Israel conflict with Iran, could drive bills sharply higher. Energy consultancy Cornwall Insights forecasts a potential 18% rise, adding about £288 to bring the typical annual bill to £1,929.
Chancellor Rachel Reeves has indicated that support will be available for "those who need it most" if bills spike, though specific eligibility criteria and implementation details remain undisclosed.
Recent changes to bill calculations have removed charges for insulation schemes and shifted 75% of renewable energy project funding to general taxation for three years, benefiting nearly all households. However, a £28 billion investment to upgrade the UK's energy grid will introduce new costs. Starting this April, typical households will see an additional £6 per month added to bills, with total contributions expected to reach £108 by 2031.
In a separate development, prepayment meter customers—numbering about six million—now pay the same rates as direct debit users. Their typical annual bill has fallen to £1,597, down from £1,711.
The government has also announced plans to reform electricity pricing by spring 2027 to reduce household bill vulnerability to gas price spikes and better pass on savings from cheaper renewable energy sources like wind and solar, though the exact scale of potential savings has not been specified.
