A representative sample of 1,502 people were surveyed by telephone during October 2023 and November 2023. They were told that energy suppliers may need to invest in a range of areas in the future, with some of these costs potentially being passed on to customers. These areas were environmental projects, network reliability and help for vulnerable customers.
Respondents were asked which areas of investment, if any, they would be willing to pay a little extra for on their bills. More than four in five of those asked (83%) said they would not be willing to pay anything extra – this is up from 63% in 2022 and 54% in 2021.
