CapWatch UK shows the maximum unit rates and standing charges Ofgem allows suppliers to charge on standard variable (default) tariffs in England, Scotland and Wales. It is not your bill. What you pay depends on how much energy you use, your meter, how you pay and your tariff. If you are on a fixed tariff, the price cap does not change your rates. Bill figures use Ofgem's typical consumption assumptions and are rounded. This site is not financial advice and does not recommend any supplier or tariff. We are not affiliated with Ofgem.
