Prepay or prepayment meter

A prepayment meter tariff means you pay upfront for your gas or electricity use. You can ‘top up’ using an app on your phone, by text or through a token or key card at a shop. More.

Default tariff

If you’ve never switched energy supplier or have switched only once, you’re likely to be on a poor value, more expensive ‘default’ tariff. Default tariffs, including standard variable tariffs, are a basic tariff from an energy supplier. More.

Here you can find information for energy suppliers on the price cap levels we have set to apply to prepayment, default and standard variable (SVT) energy tariffs. We publish updated levels for the caps in February and August to apply in April and October, respectively.
