Funding for Cavity Wall Insulation

About the Great British Insulation Scheme (GBIS)

Three Rivers District Council, in partnership with E.ON, are offering eligible residents FREE (fully funded) cavity wall insulation through the Great British Insulation Scheme (GBIS) to help residents improve the warmth of their homes and save money on their energy bills.

Benefits of Cavity Wall Insulation

• Save money on your energy bills - lower your heating costs by reducing heat loss from your home.
• Make your home more comfortable - Enjoy a more consistent and comfortable temperature throughout the year; stay warmer in winter and cooler in summer.
• Reduce your carbon footprint - Help the environment by using less energy to heat your home.
• Increase the value of your home – an energy efficient property can be more desirable to buyers.

GBIS in Three Rivers

The Council is working in partnership with E.ON – an obligated energy company - to deliver a coordinated GBIS programme locally, but you do not have to be an E.ON energy customer to benefit.

You may have received a letter from Three Rivers District Council and E.ON inviting you to apply for GBIS funding.

If you qualify for GBIS funding, E.ON’s team will help you access the funding, provide end-to-end customer support, and manage accredited installers to ensure works are completed to a high standard. If you meet the eligibility criteria, E.ON will arrange a free home survey to confirm your home's suitability for cavity wall insulation.
