Delivering socially just low-carbon solutionsThis programme of research, funded by the EBICO Trust, sought to understand the environmental and financial impacts of air-source heat pumps (ASHPs) as a low-carbon heating intervention, particularly among households without access to the mains gas network.It examined the carbon and fuel cost savings that can be attributed to the installation of ASHPs in households at risk of fuel poverty and the social and carbon benefits of ASHPs to fuel poor.
