Best External Wall Insulation Installers in 2024

Finding the right external wall insulation installer is essential for maintaining an energy-efficient, comfortable home. In the UK’s climate, where heating demands are high, quality insulation plays a vital role in reducing energy usage and cutting down on heating costs. EDF Energy reports that nearly 21 million UK homes lack adequate insulation, leading to up to 33% heat loss annually through uninsulated walls. This not only raises energy bills but also increases carbon emissions.

Installing proper external wall insulation helps retain warmth in winter, keeps homes cooler in summer, and improves overall comfort, potentially saving up to £660 per year on energy bills. With rising energy costs and a focus on sustainability, choosing a reliable insulation company has never been more important.
