Additional information

  1. Terms and conditions apply. Ofgem increased the price cap on 1st October to £1,717 for the period from 1st October to 31st December. You could save by choosing our 1-year fixed tariff 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. Read more information on how homes could save with British Gas.

  2. Based on electricity prices correct as of 01/11/2024. When you plug in your EV for 6 hours or more covering the period of 12am to 5am, you’ll qualify for a 4p credit towards your EV tariff night rate of 7.9p/kWh for all electrical consumption. 4p/kWh credit also applies at any other time of day on any other British Gas electricity tariff if your EV is left plugged in for 6 hours or more.  By managing your charger with Hive SmartCharge we’ll give you a credit each month with money back directly on your British Gas bill.
