Labour's shadow energy secretary Caroline Flint has said that the changes announced in the energy statement will "do nothing to help people with their bills this winter".
She said: "Hard-pressed energy customers struggling with the cost of living need action now, not endless reviews and consultations from an out-of-touch Government that refuses to stand up to the energy companies. "
“What we need now is a price freeze because this is the only way we can deal with the energy companies overcharging," she added.
New measures making it easier for customers to switch tariffs aimed at helping curtail energy price hikes for consumers have been slammed.
Switching your energy company or tariff can save money on your bills, and also drive competition in the market bringing further savings.
Energy Secretary Ed Davey will reveal details of a new annual review of the energy market, but will stop short of requesting a full inquiry.
