Air Source Heat Pumps

The Great British Insulation Scheme (GBIS), previously referred to as ECO+, is a government scheme designed to help people insulate their homes.

What is the Great British Insulation Scheme?

The Great British Insulation Scheme (GBIS) is a government scheme to help people insulate their homes, make them more energy efficient and save money on their energy bills. The scheme will launch summer 2023 and run until March 2026.

The £1 billion scheme is predicted to help around 300,000 households across the country with the cost of installing new home insulation and is expected to save consumers around £300 – £400 a year on their bills.*

The scheme works by obligating energy suppliers to assist customers in reducing their heating bills, through the installation of energy efficiency measures, or you may be offered the insulation for a contribution, depending on the measure and any property issues.
