Energy company performance infographic - plain text version

Company performance

Facts and figures on energy customer complaints, debt, disconnection and enforcement.

As a regulator we work closely with suppliers to improve performance including how they handle consumer complaints, fulfiltheir social obligations and provide support for vulnerable consumers.

We’ve set tough standards and enhanced transparency to help make sure consumers receive fairer treatment. We’ve also won new powers to make suppliers compensate customers directly when standards aren’t met.

Our latest numbers show 3.5 million complaints made by customers to energy suppliers in 2018*.

The main issues are:

  • billing
  • customer service
  • meter installation
  • payment methods.

We set performance targets on reliability and customer service for the companies who run the energy network that delivers gas and electricity to properties. These Quality of Service Guaranteed Standards for how quickly companies must respond to restore power in both normal and severe weather conditions. If a company fails to meet our power restoration standards, customers may be entitled to a payment. We report annually on performance, including how many power cuts the companies have.

From 2014-2018, distribution network operators have paid £29 million for failing to meet our guaranteed standards for gas and electricity distribution.
