Energy customers face a winter of discontent since bills have risen between 6 per cent and 10.8% from the 'big six' companies over the last few months. Analysts have commented on this trend. "This set of industry wide price rises could not have come at a worse time, with the UK economy still faltering and a very cold winter forecast," remarked Mark Todd, of price comparison website Energyhelpline.com. Mr Todd spoke of the "double whammy of bigger bills and lower temperatures".
