Compare supplier performance on complaints

Mae’r dudalen yma ar gael yn Gymraeg.

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.

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 suppliers must follow in the publications and update feed below.

Through the graphs below, you can view supplier performance on consumer complaints handling for:

  • Large suppliers (currently 8)
  • Medium-sized suppliers (currently 5)
  • A selection of twenty-seven small-sized suppliers
  • All above suppliers (grouped by size)

The complaints data is provided by suppliers. The figures are not audited by Ofgem.

To view all figures published by suppliers, please access their websites through the links below.

Information correct as of: February 2021

This chart shows the total number of complaints received quarterly by each energy supplier group per 100,000 customer accounts between Q2 2014 and Q4 2020.

In each quarter, we update the suppliers included in each group, reflecting new entries and exits from the domestic market during the same period. We also add those existing suppliers for which a historic trend of complaints data has become available. 

From Q3 2020, the following classification applies: the category ‘large’ refers to those suppliers whose market share exceeds 5% in at least one fuel, ‘medium’ is for those exceeding 1% in at least one fuel, but remaining below 5% in both fuels and ‘small’ for suppliers with market share below 1% in both fuels.

As of Q4 2020, the chart includes complaints for the following suppliers: large (British Gas, EDF, E.on, nPower, Scottish Power, Ovo, Bulb, Octopus Energy), medium (Avro Energy, Green Network Energy, Shell Energy, Utilita, Utility Warehouse) and a selection of twenty-seven small suppliers (Daligas, Ecotricity, Enstroga, E, Entice Energy, ESB Energy, Foxglove, Good Energy, GoTo Energy, Green, Green Energy UK, Gulf Gas & Power UK, Igloo Energy, MoneyPlus Energy, Nabuh Energy, Northumbria Energy, Orbit Energy, PFP Energy, Pure Planet, Simplicity Energy, So Energy, Social Energy, Together Energy, Tru Energy, Utility Point, Zebra Power, Zog Energy).

In January 2020, E.on acquired nPower but the migration of customers is still ongoing. For this reason, in Q4 2020, complaints data for the two companies is shown separately.

The above list includes suppliers that have exited the market in January 2021 (Green Network Energy and Simplicity Energy). These changes will be reflected in the next quarterly update.

Information correct as of: February 2021

This graph shows the total number of complaints received by large energy suppliers per 100,000 customer accounts per quarter over the period Q1 2013 to Q4 2020.

The category ‘large’ refers to those suppliers whose market share exceeds 5% in at least one fuel. We have been using this categorisation since Q3 2020 as explained here. As a result, Bulb and Octopus Energy, previously considered medium-sized suppliers, were moved to the large supplier category from Q3 2020.
