Retail Market Review

We launched the Retail Market Review in late 2010 due to concerns that the energy market was not working effectively for consumers.

The review recognised that while we had seen some improvements since the 2008 Energy Supply Probe, many of the barriers to effective consumer engagement remained. These barriers included the complexity of tariff options, the poor quality of information provided to consumers and low levels of trust in energy suppliers. 

Where we are now

We have worked with Office of Fair Trading and the Competition and Markets Authority (CMA) to carry out a review of competition in the GB energy market. This found that competition wasn't working as well as it should for consumers and led us to make a market investigation reference to the CMA. You can find out more at State of competition in the energy market assessment.

Following the CMA review we have implemented changes to the Retail Market Review rules and we propose to make further changes. We had always envisaged that a number of the Retail Market Review rules would help to reset the market and would likely be removed over time.
