Caroline Flint MP, Labour’s Shadow Energy and Climate Change Secretary, commenting on energy company complaints data from Which?, said:

“This is yet more evidence that Britain’s energy market is not working for families and businesses and is causing a cost-of-living crisis. Under David Cameron people are paying more than ever for their gas and electricity, but all too often the customer service they receive is not good enough.

“That’s why the next Labour Government will undertake the biggest overhaul of our energy market since privatisation. Our plans will break up the big energy companies, put an end to their secret deals and make tariffs simpler and fairer. And until these reforms kick-in, we will put a stop to unfair price rises by freezing energy bills until 2017, saving the average household £120.”
