Energy bills: 'The market is not working properly' - Which?
Recent cuts in consumer energy bills could have been much bigger and made much earlier, research from consumer body Which? has found.
It said energy suppliers had failed to keep standard variable energy tariffs in line with falling wholesale prices over the past two years.
Industry body Energy UK said firms had cut prices as soon as they could, but Which? executive director Richard Lloyd agued that the analysis showed "the market isn't working properly".
