The government is expected to announce measures later today to help consumers make their homes greener.
Plans are likely to include low-interest loans offered for home insulation, solar panels, biomass boilers and smart meters.
The proposals will help millions to ‘modernise their homes and cut emissions’, according to the Department of Energy and Climate Change.
Impact on consumers
But concerns have been raised that the scheme will be paid for by a levy on energy suppliers, which could be passed on to consumers through increases in energy bills.
A government spokesman said that the levy, the Renewable Heating Incentive (RHI), would have a ‘negligible impact on bills’.
The levy will be introduced in 2011, and ‘would have little impact on prices for many years’, he added.
New energy tariff launched
EDF today launched a new off-peak energy tariff, Eco 20:20.
Electricity used after 9pm or at the weekend will be 20% cheaper under the tariff.
The firm estimates that customers could save £35 a year by switching to the tariff.
