The Energy Price Guarantee will ensure that a typical household in Great Britain pays an average of £2,500 a year on their energy bill until April 2023. This Energy Bill Guarantee limits the amount you can be charged per unit of gas or electricity so your exact saving will be influenced by how much energy you consume. The level of discount people receive also depends on people’s tariff price. From April 2023 to April 2024 government is capping energy at £3,000.
