Energy savings breakdown

SAP ratings

The energy efficiency rating is a measure of the overall efficiency of a home. The higher the rating ('A' being the highest) the more energy efficient the home is and the lower the fuel bills are likely to be.

The environmental impact rating is a measure of a home's impact on the environment in terms of carbon dioxide (CO2) emissions. The higher the rating ('A' being the highest) the less impact it has on the environment.
