Want to reduce energy costs? Selling or renting a home? A BER will help you plan the best energy improvements.

What is a BER certificate

A Building Energy Rating (BER) certificate indicates your building's energy performance. It is similar to 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.

How a BER is calculated

Your BER is calculated through energy use for space and hot water heating, ventilation, and lighting.

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.

How to get a BER certificate

You will need to organise a BER assessment of the building. Your BER Assessor will give you an Advisory Report with your BER Certificate recommending the best energy saving improvements for your building. Assessments are carried out by registered BER Assessors who have been:

  • Trained under the National Framework of Qualifications
  • Passed our BER Assessor exam
  • Have registered with SEAI
