You can potentially save money by switching your Energy Supplier. If you have never switched before or you are on a standard tariff then the savings could be significant.
One of the best ways of comparing all the different offers and potential savings you can make is by using a price comparison website. CHiL has partnered with Energy Angels to provide this service and they will help you switch should you decide to go ahead.
A recent bill will show you the name of your tariff, your current payment method and your annual energy usage both in terms of money and KWH. You will need all of this information to hand when going through the switching process.
