Energy bills will rise by £209 a year to £1,850 from July, forecaster says

Energy consultancy Cornwall Insight forecasts that Great Britain's typical annual gas and electricity bill will rise by £209 (nearly 13%) to £1,850 from July 2026 under Ofgem's quarterly price cap, driven by surging wholesale gas prices linked to Iran's closure of the Strait of Hormuz amid conflict with the US and Israel. While a temporary ceasefire eased historic market highs, lingering supply disruptions mean a return to April's £1,641 cap level in autumn is unlikely, prompting calls for targeted government support for vulnerable households and accelerated renewable energy rollout to stabilize future costs.
