We work with suppliers to improve the quality, scope and prominence of their domestic consumer complaints data.
What must suppliers do?
As of July 2018, suppliers are required to submit complaints data to us on a monthly and quarterly basis. 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 six largest suppliers have voluntarily published quarterly domestic complaints data since 1 October 2012, and many smaller suppliers have done so since 1 April 2013.
Clearer complaint handling performance
Ofgem, Citizens Advice and the Ombudsman publish complaints statistics. The separate statistics show how many complaints suppliers receive, how many Citizens Advice handle, weighted by the seriousness of the complaint, and how many 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.
In addition, we have introduced a mandatory common format that all active energy suppliers must use to report their domestic and micro-business complaints information to us. You can view the templates and guidelines that suppliers must follow in the publications and update feed below.
Through the graphs below, you can view supplier performance on consumer complaints handling for:
- the six largest suppliers;
- seven medium-sized suppliers;
- thirteen small-sized suppliers; and
- all above suppliers (grouped by size).
The complaints data is provided by suppliers. The figures are not audited by Ofgem.
