What is GBIS?
The Great British Insulation Scheme (GBIS) is a UK government-based scheme established to deliver energy efficiency upgrades to homes in the UK. This program replaces ECO+ and is managed by Ofgem. And it is expected to run until March 2026.
Benefits of GBIS
You might qualify for assistance if you require any of the following types of insulation:
- Park home insulation
- Loft insulation
- Cavity or solid wall insulation
- Underfloor insulation
- Solid floor insulation
- Room-in-roof insulation
- Flat or pitched roof insulation
Investing in proper insulation for your property not only enhances comfort but also significantly reduces your energy bills. At Heatcore, our skilled installers will ensure your insulation is correctly and efficiently installed, so that your home stays warm and cosy. A properly insulated home will mean that you won’t need to keep your boiler running, leading to reduced energy bills.
