Switching your energy supplier

Mae’r dudalen yma ar gael yn Gymraeg.

If you shop around to find a deal or tariff that best suits your own energy usage, you may be able to significantly reduce your energy bill.

As the market becomes more competitive, so the energy companies increasingly have to compete with each other on price and other areas.

It is possible that other energy suppliers can offer you a deal that is more competitive than the one you are on.

Be an energy shopper

We’ve created an easy guide, Go Energy Shopping, to show how our recent Simpler, Clearer, Fairer reforms to the energy market can help you compare tariffs and get a better deal on your gas and electricity bills.

The website includes:

  • New tools to help people compare the different tariffs
  • A glossary explaining the language used on bills
  • Links to other useful sites
  • A downloadable guide which visitors can print off and read at their leisure, or pass on to family members who don’t have internet access

We have also approved a number of online comparison services that are a good place to look when comparing deals. These websites operate in accordance with our Confidence Code and can be trusted as a source of information when you are looking at different deals and tariffs.

For a list of accredited comparison websites go to: Switching your energy supplier – the Confidence Code                                                                                                                                

Where can I find more information?

You can find a list of suppliers and their telephone numbers in our Energy Best Deal booklet.

We are changing the way suppliers put together and explain their tariffs in order to make it simpler to choose which is best for you. You can read more about these changes in our section Simpler, Clearer, Fairer.

The Citizen's Advice website has information on how to move your gas or electricity meter.
