Building Energy Rating Certificate (BER)

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 homes energy performance. It is similar to the energy label for household appliances. The certificate rates the energy perfomance of your home 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 to get a BER certificate

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. BER assessments are carried out by SEAI registered BER Assessors.
