The first months of 2021 recorded a 28% rise in the demand for heat pumps.
Research by the online marketplace Rated People finds that 57% of homeowners want to be more eco-friendly when it comes to their energy use.
The report shows that only 3% of homes across the UK currently have heat pumps.
According to estimates of the Energy Saving Trust, an air source heat pump could save the average detached home with four bedrooms up to £1,300 a year, depending on the heating system that is being replaced.
