Household energy bills across Great Britain are expected to climb to a three-year high this winter, according to analysis reported by the Guardian. The government’s cap on energy prices is on track to rise by 4% from this October, the outlet reported.
The increase would take the cap to the equivalent of £1,729 a year through the final three months of 2026, according to analysis by the energy consultancy Cornwall Insight. The Guardian described the expected quarterly rise as the highest in three years.
The increase could hit struggling households especially hard this winter, when energy use typically rises with colder weather, according to the Guardian’s report of the analysis.
According to the Guardian, the rise is being driven by the impact of the Middle East war, which is feeding through to the prices households pay for electricity and gas.
The forecast increase is also expected to wipe out Andy Burnham’s VAT cut on electricity bills, meaning any relief households might have seen from that measure could be offset by the higher cap, the Guardian reported.
The price cap is reviewed quarterly, so the October change would apply to bills over the last three months of the year.
Why it matters
Energy costs are a major part of household budgets, and a rise to a three-year high during winter could squeeze families already facing financial pressure. The forecast also illustrates how international conflict can flow through to everyday bills in Britain.
