Ofgem requires the large energy companies to publish annual statements showing separately the revenues, costs and profits of their generation and supply businesses. This document summarises the results of the six large energy companies in 2012 and compares them across companies and over time.

The statements show that total profits across supply and generation fell by £133m, or 3.4%, on the previous year. This was a result of generation profits falling more than supply profits rose. Profits increased in the domestic supply market, providing an average profit margin of 4.3%. 
 
Ofgem is firmly committed to improving transparency and rebuilding consumer trust in the energy market. This summary document is part of our work to increase transparency of energy company profits.
