The Energy Performance Certificate is
broadly similar to the certificates found on
many domestic appliances.
A Certificate for a building gives the
building an asset rating based on its energy
efficiency, but doesn't take into account
how the home is used by the occupiers.
The Certificate will give the building a
rating from A to G. An A rating shows it's
very efficient, meaning lower fuel bills,
while G is inefficient, meaning higher fuel
bills. The Certificate will also show the
building's environmental impact by
indicating its carbon-dioxide emissions.
