Fewer than 200 homes have signed up for the government’s flagship Green Deal so far, the BBC has learned.
The policy, launched in January, offers long-term loans for energy-saving home improvement work.
People in England, Scotland and Wales can spend the money on new boilers or insulation and repay it over a maximum of 25 years, through energy bills.
Almost 19,000 homes have been assessed so far but very few householders have gone on to take out the loans.
The move to insulate the UK’s ageing housing stock is designed to reduce carbon emissions, keep people warm, and make energy affordable.
The idea is to give loans for home improvements – but the work must pay for itself over 25 years through lower bills.
BBC Radio 4’s You and Yours programme has learned that fewer than 200 people have signed up for the Green Deal so far.
But although the policy officially launched in January, there have been some delays with setting up the funding to allow installation work to be carried out.
