What is BER?
A BER is a Building Energy Rating and is an objective scale of comparison for the energy performance of a building ranging from A1 to G. A-rated homes are the most energy efficient and G the least efficient. The BER certificate gives an indication of how energy efficient a property is and hence how much the energy bills will be. Properties are rated on a scale from A to G where A is the most energy efficient and hence should have lower energy bills than a G rated building.
Why carry out a BER?
For anyone selling or leasing a property from 1st July 2008, a Building Energy Rate (BER) certificate will be compulsory. If you are buying or renting a house or apartment, you are entitled to see a Building Energy Rate (BER) certificate before purchasing or renting the property. The Building Energy Rate (BER) certificate can help you choose between properties so its worthwhile asking the seller/landlord or their agent for it.
How is it calculated?
A BER is based on the calculated energy performance and associated carbon dioxide emissions for the provision of space heating, ventilation, water heating and lighting under standardised operating conditions. The characteristics of the major components of the home including dimensions, orientation, insulation, and space and hot water system efficiencies are used in the calculation. The BER is not dependent on current occupant behaviour. The energy performance is expressed as:
