Energy tariff

Mae’r dudalen yma ar gael yn Gymraeg.

Tariffs are what energy suppliers charge you for gas and electricity. If you don't know what your energy tariff is, contact your energy supplier or check your last energy bill. 

You can find your supplier's contact details on your gas or electricity bill. If you don’t know who your supplier is see Who is my gas or electricity supplier?

You should talk to your supplier or look at their website to see what tariffs they have available and if you can pay less. You can also use a price comparison website to see if another supplier can offer you a better tariff. A list of Ofgem approved online comparison services are available at Ofgem Confidence Code.

If you’ve never switched energy supplier or have switched only once, you’re likely to be on a more expensive ‘default’ tariff. Default tariffs, including standard variable tariffs, are a basic tariff from an energy supplier. Find out about the default tariff price cap

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. Find out about the prepayment tariff price cap
