Ofgem and Citizens Advice commissioned BMG Research to run the latest wave of the Energy Consumer Satisfaction Survey.
This survey explores domestic consumers’ experiences of the energy market, including satisfaction with the service provided by their energy supplier.
In our Forward Work Programme 2024 to 2025, we committed to improving our collection, use and dissemination of supplier performance data. By publishing more data, we aim to enable more informed consumer choice, and thereby drive up standards.
In line with this commitment, we have published two indicators of customer satisfaction for nine energy supply groups. The two indicators are 'overall satisfaction with their supplier' and 'satisfaction with the customer service they have received from their supplier'. These indicators are based on the current survey wave's data, and can be found in a subsidiary document on this page.
This is the second time supplier-level indicators have been published from the Energy Consumer Survey Satisfaction Survey. You can find the previously published indicators on the webpage for the August to September 2023 wave.
The data reported reflects customers’ perceptions of their supplier and the service they receive based on surveying energy consumers from England, Scotland and Wales (Great Britain). The survey asked respondents to name their energy supplier, then asked questions about their experiences with that supplier. The satisfaction results are based on all respondents, regardless of whether they had been in contact with their supplier or not. The results do not provide an independent assessment of suppliers’ processes or practices.
Energy suppliers are also required by Ofgem's rules to publish their performance in the Citizens Advice Star Rating. Read more about the rating and its methodology.
Fieldwork for the survey was conducted from 18 January to 10 February 2024.
The research reached 3,855 domestic energy bill payers across Great Britain. The survey used a mixed mode data collection, including face-to-face interviewing targeted at digitally excluded respondents. Quotas were set on age, gender, region, Index of Multiple Deprivation (IMD), ethnicity and payment type to achieve a sample representative of households in Great Britain.
A sample boost of people from ethnic minority groups, prepayment and standard credit customers was also included in this wave of the survey. These customers were boosted to increase the sample size and allow for more robust analysis of these groups.
