Fine the energy firms: Privatisation has led to confusion in the market, and the Big Six providers have taken advantage

The energy market is rigged in favour of the established Big Six firms, which have consistently ignored calls from politicians and consumer groups to play fair with customers. They have set their own prices – overcharging us by around 5 per cent, according to a damning report published by the Competition and Markets Authority (CMA). Small businesses come off even worse, paying 14 per cent over the odds for their gas and electricity.
