The Green Homes Grant Voucher Scheme (GHGV) is 1 of 4 ‘Green Economic Stimulus’ programmes launched in 2020 to help homeowners install energy efficiency improvements and low carbon heat measures in their homes, and support the country’s economic recovery from COVID-19.

The former Department for Business, Energy, and Industrial Strategy commissioned Ipsos, in partnership with University College London (UCL), Building Research Establishment (BRE), and the Energy Saving Trust (EST), to conduct a process, outcome, and economic evaluation of the scheme that was completed in June 2023.
