Barclays will start paying up to £2,000 to its mortgage holders for going green in their homes.
The bank said it would run a trial to pay back customers who install new insulation, heat pumps or solar panels, among other solutions. Barclays said that most of the homeowners it surveyed wanted to improve the energy efficiency of their homes.
But most are only making small-scale improvements which do not cost much up front. This can include changing old light bulbs for more energy-efficient versions - something which has only a small impact on a home's carbon emissions.
