UK Energy Market Update – April 2026

The Ofgem price cap has just dropped to £1,641 for the average household (7% lower than the previous quarter). However, forecasts suggest a possible rise again in July 2026. Now is the perfect time to lock in a fixed or renewable tariff and protect yourself from future increases.

Switching to E.ON Next gives you 100% renewable electricity, excellent customer service, and the £50 welcome credit — all while often beating the price cap.
