A new energy regulator would be charged with producing an annual scorecard for energy suppliers, reporting on the company's performance and identifying any possible areas of concern, Labour has announced.
Shadow energy and climate change secretary Caroline Flint said: "The public have a right to be treated fairly by energy companies. Where firms fail to meet these standards, there must be tough and decisive action. Too often energy companies seem to view the regulator's fines as a cost of doing business - not as a warning to get their act together.
"Of course consumers must be compensated - but if energy companies persist in mistreating their customers they must know their licence could be on the line."
