It is a requirement for Non-Domestic EPC’s on the sale, rent or construction of buildings
other than domestic dwellings with a floor area greater than 50m2 from 6 April 2008,
that contain fixed services that condition the interior environment. All non-dwelling
EPCs must be carried out by, or under the direct supervision of our fully accredited
& trained non-domestic energy assessors, registered with an approved accreditation
There are three levels of building, Level 3, Level 4 and Level 5. The complexity
and the services used by that building will determine which level it falls under.
From October 2008 all buildings including factories, offices, retail premises and
public sector buildings must have an EPC whenever the building is sold, built or
rented. Public buildings in England and Wales (but not Scotland) also require a Display
Energy Certificate showing actual energy use, and not just the theoretical energy
rating. From January 2009 inspections for air conditioning systems were also introduced.
