Your home’s energy efficiency rating (EPC) matters. It reflects how energy-efficient your property is and plays a key role in reducing energy costs and environmental impact. The higher the rating, the better your home retains heat and uses energy efficiently.

One of the most effective ways to improve your EPC rating is by properly insulating your walls. At Bro-Therm, we provide professional external wall insulation across London and the surrounding areas, working on all types of properties from cosy family homes to large residential buildings.
