What is a BER certificate?
A Building Energy Rating (BER) certificate indicates your building’s energy performance. It is like the energy label for household appliances.
The certificate rates your building on a scale of A-G. A-rated homes are the most energy efficient and will tend to have the lowest energy bills. G-rated are the least energy efficient and tend to have the highest energy bills.
How a BER is calculated?
Your BER is calculated through energy use for space and hot water heating, ventilation, and lighting. A measured survey of the property is carried out and a room by room survey completed. It is a non-invasive survey.
The number of people likely to occupy a building is also taken in consideration. This is based on the average number of occupants in buildings of a similar size.
Who needs a BER Certificate or when is one required?
A BER is required for all homes that are for sale or for rent, including unoccupied new builds.
What buildings are exempt from needing a BER?
There are some exemptions from the requirement of a BER, these are:
protected structures or proposed protected structures
places of worship or buildings used for the religious activities of any religion
certain temporary buildings
industrial buildings not intended for extended human occupancy with a low installed heating capacity (≤10 W/m²);
non-residential agricultural buildings with a low installed heating capacity (≤10 W/m²);
