What is the Great British Insulation Scheme?

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

The £1 billion scheme will help around 300,000 households across the country with the cost of installing new home insulation, and will save consumers an average £400 a year on their bills.

The scheme works by obligating energy suppliers to help customers reduce their heating bills by installing energy efficiency measures such as loft and cavity wall insulation. The cost of this may be covered in full through the scheme, or you may be offered the insulation for a contribution, depending on the measure and any property issues.
