Ministers have denied putting pressure on energy firms to freeze their prices until after the next general election.
Their rebuttal centres on claims by the power suppliers that they had been asked not to increase their tariffs by more than the wholesale energy market rates until the next general election, due in 2015.
The report, from the BBC, was denied by the British government, which said instead that its focus was on increasing market competition over the next few years.
It added that Chancellor of the Exchequer George Osborne's interim budget statement, due next week, would outline new measures, including steps to cut the burden of the cost of implementing European Union guidelines on energy efficiency for homes for the energy companies.
The government has strongly denied earlier reports that it was taking any steps to ask energy companies to keep prices down until after the next general election, due in two years' time.
