A Domestic Energy Assessor (DEA) assesses the energy efficiency of houses and suggests how it can be improved. Whenever homes are put onto the market or rented out an EPC is required. The requirement for EPCs has now been expanded and is now necessary in most buildings and residences.
A DEA inspects properties to collect information on the building type, heating and hot water systems, take note of dimensions of rooms, types of windows, number of fireplaces. This information is then used to produce an energy efficiency rating, “A” being the most energy efficient and “G” being the least, and an Energy Performance Certificate is then produced. DEAs note everything that is required to produce the certificate and give practical advice to occupiers on how to improve the energy efficiency of their home such as insulation and heating efficiency.
Domestic Energy Assessors collect the information about the home, its fabric, lighting and heating. Domestic Energy Assessors may use information which has been collected previously about the building. The Domestic Energy Assessor will provide recommendations and advice which is appropriate to the building. The assessor will suggest changes which will contribute to gaining better energy efficiency.
Display Energy Certificate
Display Energy Certificates are only presently required for certain public buildings. By law, DECs must be on display in these buildings if they have a total useful floor area over 1,000m 2, are occupied by a public authority or an institution providing a public service (further defined as 'one providing a service traditionally associated with local or national Government') to a large number of persons and therefore visited by those persons. Display Energy Certificates are based on actual energy consumption, as shown from meter readings and other fuel consumption. The DEC must show the certificate reference number, the address of the building, the name of the Energy Assessor, trading name, the name of the suitably qualified Non Domestic Energy Assessors’ recognized Accreditation and the date when the DEC was issued. DECs must be renewed after one year, though the accompanying Advisory Report lasts seven years.
