*Slash the cost of your energy bill by £273 on average.  Average saving is based on customers that switched a gas and/or electricity contract between 1st June 2017 and 6th December 2017.  For 99% of customers we were able to directly compare the deal switched to via a Dixons Carphone service vs. the published price of the customer’s existing supplier/tariff (as identified by user).  The saving is a projected annual saving from the new deal purchased, based on the usage data shared with us.  Your actual savings may vary.  Date 07/12/2017
