UK energy price cap set to rise 4% to an average £1,723 per household from October
Executive summary: Ofgem raised the UK energy price cap by 4%, resulting in an average annual household energy bill of £1,723 effective October 2026. The increase raises living costs for millions of households, affects disposable income, and may strain public finances if further subsidies are needed.
Who is involved: Ofgem (UK energy regulator), UK households, gas and electricity suppliers, and the UK government which oversees energy policy.
Likely next: The new cap will take effect on 1 October 2026; the government may announce targeted winter support, and Ofgem will review the cap again quarterly based on wholesale market movements.
Ofgem announced a 4% increase in the energy price cap, raising the typical annual bill to £1,723 starting October 2026. The rise reflects persistently high international gas prices that continue to push up wholesale energy costs in the UK. While the increase was anticipated, it adds further pressure on household budgets and may prompt calls for additional government support measures.
