How do I switch energy supplier to save money on my bills?

Energy companies often offer good discounts for new customers which is why many people are switching their energy supplier each year. It is always a good idea to talk to your current energy supplier to see if they can improve on the rates or tariffs you have been offered.

Step 1

If you want to switch supplier you will need the following information (found on your energy bill):

  • the name of your current tariff
  • how much gas or electricity you have used in the last 12 months
  • your current payment method
  • your postcode

Step 2

Find the best deal for you. You can either use a price comparison service or contact each energy supplier directly.

Use one of the price comparison sites accredited by Ofgem's Confidence Code:

Step 3

Once you have agreed a new contract your energy supplier could switch from between three and 14 days, it depends on the cooling off period that the company offers. You should remember to cancel any payment method with your previous energy company. 

If you have any difficulties during the process you should speak with the energy company in the first instance. If you require further advice you can contact the Citizens Advice consumer helpline on 03454 04 05 06.
