Here you can view the price cap levels we have set for suppliers to apply to prepaymentopen key term pop-up and default energy tariffs, including standard variable (SVT)open key term pop-up energy tariffs. Your energy bill isn’t capped – this will vary depending on how much energy you use. The caps apply to the price your supplier charges for each unit (kWh) of electricity and gas used, and your standing charge.
It's best to contact your supplier for your specific tariff price details. You can find their contact details on a recent bill, or see find my supplier.
If suppliers raise their prices, they must write to inform you before a new price applies, and ensure you have enough time to consider your options and switch away if you want to.
