How to switch energy company

Over 250,000 people switch energy company or tariff every month. Energy companies want to make the switching process as simple and hassle-free as possible, which is why they have recently launched the Energy Switch Guarantee. The Guarantee is an industry-led initiative which aims to increase customers’ confidence in the switching process.

There are several ways to switch. You can:

  • phone your energy company or look at their website to find out what deals they have
  • use one of the accredited price comparison websites
  • or you can switch at events in shopping centres and supermarkets
