Great British Insulation Scheme (GBIS)
Support to help make your home warmer, more energy efficient, and cheaper to run through improved insulation.
The Great British Insulation Scheme helps eligible households access insulation improvements that reduce heat loss and improve comfort, delivered by approved installers across the UK.
What is the Great British Insulation Scheme?
The Great British Insulation Scheme (GBIS) is a government-backed programme designed to help homes with poor energy efficiency improve their insulation.
The scheme focuses on reducing heat loss by funding insulation measures in properties that would benefit most, helping households stay warmer and use less energy.
Improvements are delivered by approved installers, with funding provided through the scheme rather than paid upfront in most cases.
Who is the GBIS scheme for?
GBIS is aimed at households living in properties that would benefit from improved insulation.
You may be suitable if:
Your home has a low energy performance rating
You are a homeowner or private tenant (with landlord permission)
Your property currently has limited or outdated insulation
Your household meets certain criteria linked to energy efficiency or income
Eligibility can vary depending on your circumstances and your local authority, so a quick assessment is usually required.
