A Guide to Green Mortgages in Ireland (2025)
As sustainability becomes a priority in Ireland, green mortgages have emerged as a popular financial product for environmentally conscious homeowners. These mortgages offer incentives for purchasing or upgrading homes to meet energy efficiency standards, aligning financial savings with environmental benefits.
What is a Green Mortgage?
A green mortgage is a home loan that offers lower interest rates or other benefits to borrowers who purchase, build, or upgrade homes with high energy efficiency. To qualify, properties typically need a Building Energy Rating (BER) of B3 or higher. The BER measures energy efficiency on a scale from A (most efficient) to G (least efficient), with A-rated homes offering the best performance and lowest energy costs.
Benefits of Green Mortgages
- Lower Interest Rates: Green mortgages often come with reduced interest rates compared to standard mortgages, leading to significant savings over the loan term.
- Reduced Energy Bills: Energy-efficient homes require less heating and electricity, cutting utility costs.
- Increased Property Value: Homes with higher BER ratings are more attractive to buyers and may command higher resale values.
- Environmental Impact: By promoting energy-efficient housing, green mortgages contribute to reducing carbon footprints and supporting Ireland’s climate goals.
Eligibility Criteria
To qualify for a green mortgage in Ireland:
- The property must have a BER of B3 or higher.
- Borrowers can qualify by purchasing an energy-efficient home, building one, or upgrading an existing property to meet the required BER standard.
- A valid BER certificate (dated within the last 10 years) is necessary.
How Green Mortgages Work
Green mortgages function similarly to standard mortgages but with added incentives:
- Borrowers receive discounts on fixed interest rates.
- Some lenders offer cashback incentives or further rate reductions if the BER rating improves during the mortgage term.
- Fixed-rate terms typically range from 2 to 5 years.

How to Improve Your Home’s BER
If your property doesn’t meet the B3 threshold, you can make upgrades such as:
- Installing better insulation
- Upgrading windows to double or triple glazing
- Adding renewable energy systems like solar panels
- Replacing outdated heating systems with energy-efficient alternatives
Grants from the Sustainable Energy Authority of Ireland (SEAI) can help offset renovation costs.
Pros and Cons of Green Mortgages

Is a Green Mortgage Right for You?
Green mortgages are ideal if you:

However, it’s essential to compare all mortgage options, as some non-green loans might offer better overall value depending on your circumstances.
