The government's flagship programme to transform the energy efficiency
of 14 million homes in the next decade will fail and only reach only two to three million households, according to an unprecedented attack from the government's own climate advisers.
The warning comes from the Committee on Climate Change (CCC), which on Tuesday for the first time published an open letter
criticising government policy. It follows soaring energy bills and the news that one in for homes are now in fuel poverty.
The "green deal" plan, which will start in October 2012
, will allow homeowners to take out loans to pay for insulation, with the guarantee that the savings on their energy bills will be greater than the loan repayments. Currently, energy companies have a legal obligation to enable their customers to improve their energy efficiency.
