BER Information


What is a BER

A Building Energy Rating or BER is an energy label with accompanying advisory report for homes. The rating is a simple A to G scale. A-rated homes are the most energy efficient and will tend to have the lowest energy bills.
BER Cert Advisory Report
A BER makes the energy performance of a home visible to prospective buyers and tenants allowing them to take energy performance into consideration in their purchase or rental decision. The Advisory Report identifies potential energy
performance improvements that could lead to better comfort levels, reduced energy use and costs.
A BER is valid for up to 10 years provided that there is no material change to the home that could affect the energy performance. A Provisional BER, derived from
the plans for an as yet unbuilt home, has a maximum validity of 2 years.

Who needs a BER?

An owner must provide a BER to prospective buyers or tenants when a home is offered for sale or rent. There are exemptions for certain building categories e.g. protected structures and temporary buildings. A homeowner must obtain a BER before a new home
is occupied for the first time regardless of whether it is offered for sale or rent. BER details must be included on advertisements
when a home is offered for sale or rent.

How is a BER 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: (a) Primary energy use per unit floor area per year (kWh/m2/yr) represented on an A to G scale; and (b) Associated Carbon Dioxide (CO2) emissions in kgCO2/m2/yr
A BER is only an indication of the energy performance of a home, similar to the concept of a fuel economy (miles per gallon or litres per 100km) rating for a car. A BER does not include electricity used for purposes other than heating, lighting, pumps and fans. Therefore the energy used for electrical appliances such as cookers, fridges, washing machines and TVs is excluded.
