The Great British Insulation Scheme (GBIS) is a supplier obligation which is being developed by the UK government’s Department for Energy Security and Net Zero (DESNZ). The aim of the scheme is to deliver energy efficiency upgrades in homes in Great Britain.

GBIS will target the worst performing homes and will include a ‘general eligibility group’, covering homes in the lower council tax bands, with an EPC of D and below. Under the scheme, suppliers may offer to install a single retrofit insulation measure with the cost partially or fully subsidised.

DESNZ commissioned the Behavioural Practice at Kantar Public UK to carry out research to understand the extent to which owner-occupiers are willing to co-fund the installation of retrofit measures in their home. This report presents findings from an online discrete choice experiment and a follow up survey with owner occupiers in England, Scotland and Wales who meet the eligibility criteria for the GBIS general eligibility group.
