What Exactly Is Changing — and Why
From 1 April, Ofgem's price cap, the energy regulator (ofgem.gov.uk), which sets the cap under powers from GOV.UK legislation (gov.uk/government/organisations/ofgem) will set the maximum electricity unit rate as determined by Ofgem (ofgem.gov.uk), subject to FCA consumer protections at 24.67p per kilowatt hour (down 10.9%) and the gas rate at 5.74p per kWh (down 3.2%). For a household using a typical 2,700 kWh of electricity and 11,500 kWh of gas per year, paid by direct debit, this translates to an annual bill of £1,641 — down £117 from the current January–March cap of £1,758.
The primary driver is the November 2025 Budget, in which Rachel Reeves scrapped the Energy Company Obligation (Eco) scheme and shifted several green energy levies away from bills and into general taxation. This policy change alone was intended to deliver a £150 annual saving, but rising network maintenance costs — the expense of strengthening power lines, cables and gas pipes for the energy transition — clawed back roughly £66, diluting the saving to £117.
Critically, the savings apply to all households, not just those on variable tariffs governed by the price cap. The approximately 40% of homes on fixed-rate energy deals will also see the government's intervention passed on by their supplier. Ofgem has confirmed it has enforcement powers if suppliers fail to pass on the savings. Households on prepayment meters will pay slightly less than direct debit customers, with a typical bill of £1,597 per year, while those paying quarterly by cash or cheque face a higher typical bill of £1,772.
