Ofgem 13% Price Cap Rise Takes Effect — Households Feel Immediate Cost Jolt
Ofgem’s new energy price cap took effect from today, with household energy bills up 13% year-on-year for the average dual-fuel household. The rise is the largest single-quarter cost-of-living jolt of 2026 so far and immediately becomes political territory for the incoming Burnham government. Standing charges are rising alongside unit rates, meaning even low-usage households will see meaningful bill increases through the summer. The Warm Home Discount scheme has been extended but critics say the expansion is not enough given the scale of the price rise. Fixed-tariff customers are protected until their deal ends. The Burnham team is expected to review the price-cap architecture as an early policy priority.
The Ofgem price cap has become the effective benchmark for domestic UK energy pricing since 2019. The 13% rise reflects the delayed pass-through of Q1 wholesale gas price rises and the impact of higher network costs. The cost-of-living angle will be politically significant given the timing of the Burnham leadership transition — the incoming Prime Minister will inherit an immediate policy question about whether to reform the price-cap architecture, extend the Warm Home Discount further, or accelerate the switch to smart-meter time-of-use pricing. Warm Home Discount reform is one of the areas Burnham has flagged in speeches as a priority.
