Building Energy Rating 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 does not 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
