In the pursuit of a warmer and more energy-efficient home, Mr. and Mrs. Harris reached out to Energy Challenge for advice.
Their semi-detached property, built in the 1970s, was losing a significant amount of heat through its uninsulated cavity walls, resulting in high energy bills and cold rooms during winter.

After a free home survey under the ECO4 scheme, our team recommended full cavity wall insulation using high-performance bonded beads.
The installation was completed in just one day with minimal disruption, and the results were immediate — their home retained heat much better, and the heating bills saw a noticeable drop.

Mr. and Mrs. Harris were thrilled not only with the professionalism of the team but also with the long-term benefits and grant funding that made the work completely free.
