Responding to Ed Davey's statement, Labour shadow energy secretary Caroline Flint has attacked the coalition's plans to reform the energy market.
She said that the reform mean that "energy companies will still be allowed to put up people's bills this winter".
"There is not a single measure that will cost the energy companies a single penny," she added.
The coalition has unveiled measures it says will knock £50 off the average energy bill, but some of that cost will be absorbed by taxpayers.
The Government has laid out its ideas on how to cut energy bills this winter - but the plan has been put together in haste.
