What is a BER rating, and why does it matter?

Buying Residential

A Building Energy Rating (BER) is an energy efficiency assessment for homes in Ireland, ranking properties from A (most efficient) to G (least efficient). This rating impacts your heating costs, comfort, and overall property value.

✔ High BER Ratings (A or B) – Homes with better insulation, modern heating systems, and energy-efficient windows tend to have lower utility bills and higher resale value. Many lenders offer green mortgages with lower interest rates for properties with a strong BER rating.
✔ Low BER Ratings (E, F, or G) – Older homes with poor insulation, outdated heating systems, and inefficient windows may lead to higher energy costs. Buyers should factor in potential renovation expenses such as insulation upgrades, double glazing, and heating system improvements.
✔ Legal Requirement – A BER certificate is mandatory when selling or renting a property in Ireland, and buyers should always check the BER rating before committing to a purchase.

Understanding a property’s BER rating helps buyers make energy-efficient choices that can save thousands on future energy bills and increase the home’s long-term value.
