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.

There are some exemptions from the requirement of a BER, these are:
- national monuments
