Additional information
-
Terms and conditions apply. You could save by choosing our fixed tariffs instead of our Standard Variable tariff, which is governed by Ofgem’s price cap. Savings based on average domestic gas and electricity energy consumption values (gas: 11,500kWh, electricity: 2,700kWh). The exact savings achieved will vary depending on your energy use. Our customers taking part in PeakSave are saving £24 on average per year. PeakSave average savings per household up to 30th September 2024. If the price cap falls after April 2025, you could pay more for your energy with a fixed tariff. See our latest predictions for the price cap.
