iSupplyEnergy customer score
In September and October 2015 we surveyed 8,902 UK adults who pay for their household energy, about their experience with their gas and electricity suppliers.
The percentage customer satisfaction score is based on the responses consumers gave for both overall satisfaction and their likelihood to recommend the energy supplier to a friend. Both questions are given equal weighting, and only those giving a valid response to both questions are included in the analysis. The responses are analysed and scaled to give a rating from 0-100%.
