Home insulation grants and funding

InstaGroup is approved to access grants and funding on behalf of customers to cover the cost* of installing a range of home energy efficiency improvements.

If you’re eligible for the ECO scheme or a local council grant we can let you know. Ask us about home insulation grants.

More than insulation

We understand that it can take more than insulation to make a house energy efficient. That’s why we offer a ‘whole home’ solution that includes windows, doors and heating.

We can upgrade heating systems to replace inefficient boilers, and we’re getting ready to provide low carbon alternatives for home heating such as air source heat pumps and solar energy.

Extending or improving your home?

InstaGroup works with builders both large-scale and small to insulate new homes from the ground up.

If you’re improving or adding to your existing property, we can insulate your extension or new building at the same time. We insulate from inside, which helps to streamline the building process and also ensures external walls stay immaculate.

We also offer external render without insulation for a quick and cost-effective way to refresh the look of your property and add instant kerb appeal.
