WHAT IS BER?
A BER — or Building Energy Rating — is a certificate that shows how energy-efficient a home is, rated on a scale from A to G. It’s similar to the energy label you see on a fridge or washing machine — but for your whole house.
WHAT DOES BER MEASURE
Your BER takes into account things like:
Insulation and ventilation
Hot water efficiency
Windows & doors
Use of renewable technologies
Heating system and controls
The overall energy demand per square metre
WHAT DO THE RATINGS MEAN?
A1 - A3
Extremely energy-efficient. Little energy wasted. Likely to have excellent insulation and renewable systems.
B1 - B3
Good performance. Meets modern energy standards.
C1 - C3
Average. Often seen in homes built after 2000. Some room for improvement.
D1 - D2
Poor efficiency. Common in older homes with little insulation or outdated systems.
E - G
Very poor. High heating costs and significant energy loss. Likely to benefit from retrofitting.
WHY IS BER
IMPORTANT?
It’s more than just a certificate — your BER can impact energy bills, comfort, property value, and grant eligibility.
Legal Requirement
A BER is required when selling, renting, or advertising a property — and for most SEAI grant applications.
Cost Savings
A higher BER means lower energy bills. The certificate includes tailored advice to help you improve your rating.
Better Comfort
Homes with a better BER are warmer in winter, cooler in summer, and more comfortable overall.
Added Value
Energy-efficient homes are more attractive to buyers and renters — and often more valuable.
Mortgage & Retrofit Ready
Many lenders now look for a BER in mortgage applications, especially if you're borrowing for energy upgrades.

How Long Is It Valid?
A BER certificate is valid for 10 years, unless major upgrades are made to the home that could affect its energy performance.
