As part of Government's commitment to reducing Carbon Dioxide emissions and helping the fight against Global Warming every home's energy efficiency has to be assessed. All homes sold or rented on the open market are legally required to hold an official EPC (Energy Performance Certificate), which may only be produced by a qualified Domestic Energy Assessor (DEA) or Home Inspector.
The EPC gives you information on your home's energy use and carbon dioxide emissions and also explains how these can be reduced. Each property is scored out of 100 and graded between 'A' (most energy efficient) and 'G' (least energy efficient), with the average home being rated as 'D'. The report provides the rating for your house and then goes on to explain how the rating has been calculated,what improvements could be made, and how much might be saved if those recommendations were implemented.
Typical recommendations might include improvements to loft or cavity wall insulation, but the EPC could also include advice on whether solar or wind power would be cost effective in your particular home. The idea is to reduce the Carbon Footprint of the whole country by raising awareness of energy saving measures, as currently 27% of all carbon dioxide emissions come from domestic homes.
