GOV.UK BACKED SCHEME
Free Home Insulation Upgrades
Take advantage of the Great British Insulation Scheme (GBIS) where there is no pre-requisite to be in receipt of benefits to access no-cost government-funded insulation improvements that enhance your home’s energy efficiency. This scheme offers targeted single insulation measures, ensuring your home stays warmer and energy bills stay lower.

Improve Your Home’s Energy Efficiency with the Great British Insulation Scheme!

How the Great British Insulation Scheme Works
The Great British Insulation Scheme provides free insulation upgrades to eligible homes, focusing on single measures like loft and cavity wall insulation to help reduce energy consumption and costs.
The scheme complements the Energy Company Obligation (ECO4) scheme, yet unlike ECO4’s ‘whole house’ approach, this scheme will mostly deliver single insulation measures. This ensures a broader reach to homes needing specific insulation upgrades.
How do I qualify?
Valid Council Tax Band Needed
Scotland and Wales: Homes in Council Tax bands A-E.
