All about EPC
A certificate of energy efficiency will tell you how efficiently the building uses energy. The better the rating, the more efficient the building is, and the lower your energy bills will likely be. The energy efficiency of the building is shown by a carbon dioxide (CO2) based index.
This energy rating is based on the features of the building itself (the fabric) and the services it provides (such as heating, ventilation and lighting).
The asset ratings will reflect the age and condition of the building. The recommendation report will provide recommendations on how to use the building more effectively and make cost-effective improvements. These may include things like improving the building's energy performance.
