Lower your energy bills with insulation
Did you know you can save up to £775 per year on energy bills by installing cavity and loft insulation in your home?(1)
We work with trusted insulation installers who can help you install the insulation you need to make your home more energy efficient.
Why insulate your home through EDF?
A typical house with no insulation will lose 33% of heat through walls and 25% through the roof(2).
We've assisted over 113,000 households in achieving energy efficiency improvements in the past five years. We are dedicated to helping you reduce your energy consumption in the future through working with our certified local installers. Our goal is to help customers obtain the appropriate funding for insulation installations. This can be accomplished through our ECO4 scheme, which offers a bundle or recommended improvements by an installer, or through our Great British Insulation Scheme, which provides support for insulation installation costs.
What types of insulation do our installers offer?
You may need to upgrade your ventilation to get the best out of your insulation. Not only are they designed to get better quality air through your home, but they can also help prevent against damp, mould and filter out dust and other pollutants. Your installer will be able to advise.

What about solid wall insulation?
Homes built before the 1920s are likely to have solid walls. Solid walls are created from a single solid material such as brick, masonry or concrete. Adding an extra external or internal layer provides insulation.
We currently don't offer solid wall installations. Our guide however helps you understand the benefits of solid wall insulation and tackle the most asked questions.
