A Building Energy Rating (BER) certificate is similar to the energy label for 
household appliances.
From January 2009, a BER Certificate is compulsory for all buildings being constructed, or offered for sale or rent.
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.
A BER certificate is valid for a period of up to 10 years while there are no changes made to the dwelling that will negatively affect its energy performance.
As 10 years have passed since the introduction of the compulsory certificate, you may need a new certificate.
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:
- Appropriate building related qualifications
- Passed our BER Assessor exam
- Registered with SEAI
