Energy price caps and the Warm Home Discount

Mae’r dudalen yma ar gael yn Gymraeg.
Price caps are here to ensure you pay a fairer price for your gas and electricity, and to protect against overcharging. Here we explain how it works and applies if you get the Warm Home Discount, and how you can save even more by switching. 

If you get the Government’s Warm Home Discount (WHD) and pay for your gas or electricity using a prepayment meter, you are protected by the prepayment meter price cap.

If you get the WHD and are on a ‘standard variable’ tariff or an energy contract you’ve not chosen (a ‘default’ tariff) your energy prices are protected by the default tariff cap. This started on 1 January 2019.

The default tariff cap has different levels set to reflect how you pay, where you live and the type of energy meter you have.

Not sure what your energy tariff is?

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?
