We’ll get you the best results from insulation

We understand that all homes are unique – even two identical-looking houses in the same street may need a different solution. That’s why our approach to saving energy is tailor-made for each property.

Every material we specify, every insulation system, draught prevention technique and vent we include is designed to deliver the best result for that particular home.

Because we don’t just install insulation: we install peace of mind. We plan every installation to prevent cold and condensation all around the property. Our attention to detail from survey onwards will look after a home years down the line, while saving maximum energy.

Cavity Wall Insulation

Cavity Wall insulation is for properties with external walls that are made up of two layers of brick with a gap (or cavity) between them. The cavity is expertly filled with the recommended insulating material, keeping in around a third of the heat currently lost through uninsulated cavity walls. It's a quick and effective way to save you up to £480 every year on energy bills3. Our Cavity Wall installations come with a 25-year guarantee.

Loft Insulation

Loft insulation is easy to install and can immediately save 25% of the heat that is lost through an uninsulated roof 4. InstaGroup can install all-new insulation, or check your existing loft insulation to see if it needs topping up to the current recommended depth of 270mm. Our experienced installers could warm up your home within an hour5 -- and you'll continue to feel the benefits for at least 40 years.
