Energy action plan
Downing Street has said that new legislation will place an "obligation" on energy firms to provide the lowest tariffs to customers.
David Cameron announced today that the Government will legislate to drive down energy bills. Speaking at Prime Minister's Questions, Mr Cameron told MPs: "We will be legislating so that energy companies have to give the lowest tariffs to their customers, something the Labour party didn't do in 13 years."
Following his comments, Downing Street said the Government was acting because customers were failing to secure the best deals at present.
"At the moment people are encouraged to switch tariffs but many don't", said the Prime Minister's Official Spokesman. "We need to place more obligation on the companies."
The spokesman added that full details of the plans would be set out "in due course".
Separately, senior Cabinet members were due to meet today to thrash out a policy for meeting the UK's future energy demands.
Nick Clegg and Energy Secretary Ed Davey, who want to see more support for renewables including wind power, were due to meet with Mr Cameron and George Osborne.
