Compare gas and electricity prices

Mae’r cyngor hwn yn berthnasol i Cymru

You can use our price comparison tool to compare prices from different energy suppliers.

You’ll need the name of your supplier and tariff - this will be on your energy bill.

You can get a more accurate quote if you know your annual consumption - this is the amount of gas or electricity you've used over the last year, measured in kilowatt hours (kwh). Find this on your annual statement if you have one.

If you have a non-Economy 7 ‘multi-rate’ electricity meter

You should call your chosen supplier before you switch to a single rate tariff.

Tell them you have a multi-rate meter and ask them to double-check the price and tariff you’ve seen online.

Check which type of meter you have before you start if you’re not sure.
