Energy ratings have become a decisive factor for Irish home buyers. As property prices remain high and energy costs continue to rise, buyers are looking beyond location and size to understand the long-term cost of owning a home. A property’s Building Energy Rating now plays a central role in affordability, mortgage approval, and resale value across Ireland.
In competitive markets such as Dublin, Cork, and Galway, energy efficiency is no longer a “nice to have” — it is a key consideration shaping buyer behaviour.
A Building Energy Rating (BER) measures a home’s energy performance on a scale from A1 (most efficient) to G (least efficient). It estimates how much energy a property will use for heating, lighting, and ventilation.
For buyers, a higher BER means:
According to the Sustainable Energy Authority of Ireland , homes with higher BER ratings can cost up to 50% less to heat than lower-rated properties. As energy prices remain volatile, this difference is increasingly important to buyers budgeting for mortgage repayments.
There is a growing link between BER ratings and property values. Data from Irish property listings consistently shows that homes with A- and B-rated BERs command higher prices and sell faster than similar lower-rated homes.
This trend is visible across major cities, where buyers are willing to pay a premium for certainty around running costs.
First-time buyers are among the most affected by energy ratings. With limited budgets and strict lending rules, energy efficiency can directly influence mortgage approval.
Irish lenders now offer green mortgages with lower interest rates for homes rated A or B. These products are designed to reward buyers purchasing energy-efficient homes, helping to reduce long-term borrowing costs.
In contrast, buyers purchasing lower-rated homes must factor in:
For many first-time buyers, choosing a higher-rated home improves overall affordability — even if the purchase price is higher.
Buyers considering older properties should understand the cost of improving a BER. The SEAI offers grants for insulation, heat pumps, and energy upgrades, but retrofitting can still require significant upfront investment.
This reality is pushing many buyers towards newer homes or recently upgraded properties, where energy performance is already optimised and compliant with modern standards.
Energy efficiency is also influencing rental demand. Renters are increasingly aware of energy costs, particularly as electricity and gas prices remain high.
Energy-efficient rental properties:
For landlords, a higher BER can justify stronger rental yields while future-proofing properties against tighter energy regulations.
Energy ratings will continue to shape the Irish property market. Government policy is moving towards stricter efficiency standards, and homes with poor BER ratings may face reduced demand or declining value over time.
As sustainability targets tighten and buyers become more informed, energy efficiency will remain a key differentiator between properties.
Energy ratings now sit at the centre of Irish home buying decisions. For buyers, renters, and investors alike, understanding a property’s BER is essential for managing costs, securing finance, and protecting long-term value.

A Building Energy Rating (BER) is an energy performance certificate that indicates the energy efficiency of a property on a scale from A to G. It assesses various aspects such as insulation and heating systems, providing potential buyers with an insight into expected energy costs.
Energy ratings are crucial for home buyers as they can significantly affect property value and running costs. A higher BER often correlates with lower energy bills, making these homes more appealing in the long run, especially as energy prices continue to rise.
In Dublin, properties with higher energy ratings typically command higher rental prices. This trend reflects the growing demand for energy-efficient homes among renters, who are increasingly conscious of their energy bills and environmental impact.
Owning an energy-efficient home offers several benefits, including reduced energy costs, lower carbon emissions, and increased comfort. Furthermore, these properties often have higher resale values, making them a smart investment for homeowners.
Yes, the Irish government offers various grants and incentives aimed at improving energy ratings. These can significantly help homeowners upgrade their properties to more energy-efficient standards, making it easier to achieve better BER scores. For more information, visit FindQo.ie.
