Customer service data
Our interactive customer service indicators
Energy suppliers offer more than different prices – they also offer different levels of customer service. These indicators give a snapshot of the performance trends we monitor on supplier customer service.
Customer service highlights July 2024

Service quality
We all expect certain things from our energy suppliers, like understandable bills and the ability to contact them when we need to. These indicators show customer satisfaction with those and other fundamental points for the overall market and across different groups of suppliers. The data comes from a dedicated energy consumer satisfaction survey conducted for Ofgem and Citizens Advice by BMG Research. The tracking survey started in 2018 and is conducted at regular intervals.
Research reports with findings from the energy consumer satisfaction survey are published here on a regular basis: Ofgem consumer research | Ofgem.
For previously published customer satisfaction indicators based on a different survey and methodology as of February 2017 please see Customer satisfaction indicators - previous updates | Ofgem.
If things go wrong
No-one wants to have to complain about their energy supplier, and if you do, you want them to resolve your problem as soon as possible. Ofgem, Citizens Advice and the Ombudsman publish complaints statistics. The separate statistics show how many complaints suppliers receive, how many complaints Citizens Advice handle, weighted by the seriousness of the complaint, and how many complaints are accepted by the Ombudsman after failing to be resolved by the supplier. This helps to show a full picture of the customer’s complaint from start to finish.
The complaints data is provided by suppliers. As of July 2018, suppliers are required to submit complaints data to us on a monthly and quarterly basis. See our guidance on submitting customer complaints data. They also publish domestic complaints data on their websites, including their 'top 5' reasons for complaints and the measures they are taking to improve how they handle customer complaints. The large legacy suppliers have voluntarily published quarterly domestic complaints data since 1 October 2012, and many smaller suppliers have done so from 1 April 2013. At present, we generally cover suppliers with at least one full year of data. Missing data points in the complaint charts are due to suppliers failing to make the information available in time for our publication update or due to cases where we have asked suppliers to resolve data discrepancies.
Extra support
Sometimes you might need your supplier to provide you additional support, for example by helping you to repay an energy debt. These indicators compare how well suppliers support their customers.
