What is the Great British Insulation Scheme?
The Great British Insulation Scheme (GBIS) is a UK government initiative to help homeowners and tenants improve their home insulation. It helps keep your home warm in the winter and cool in the summer, saving you money on energy bills.
GBIS is government-funded and aims to help eligible households save around £300 a year on energy bills. Around 300,000 people can benefit from free or reduced-cost insulation through this scheme.
What makes GBIS funding special is that it helps everyone, especially those who need it the most. It specifically helps those on the lowest incomes and households with the least energy-efficient homes, making a real, widespread impact.

Insulation measures available under the Great British Insulation Scheme
Once our surveyor has completed their survey, we will be able to determine which of the following insulation measures is most suitable for your home. This might include:
Cavity Wall Insulation
Cavity wall insulation fills the gap between your home’s inner and outer walls with insulating material.
This reduces heat loss, lowers your energy bills, and keeps your home warmer. It’s a cost-effective way to boost comfort and add value to your property.
Loft Insulation
Loft insulation involves adding insulating material to your attic or loft space to prevent heat from escaping through the roof.
For you, this means lower energy bills, a warmer home in the winter, and a cooler one in the summer. It’s an easy way to enhance comfort, reduce energy costs, and increase your home’s value all year round.
