Green Mortgages in Ireland: A Comprehensive Guide to Energy-Efficient Home Loans

What is a Green Mortgage and Who is Eligible?

Green Mortgages have gained popularity as homeowners seek ways to reduce their carbon footprint and save on energy bills. These home loans incentivize energy-efficient and environmentally-friendly features in a property. Green Mortgages function like standard mortgages but offer lower fixed interest rates to those who purchase or own an energy-efficient home.

Eligibility for Green Mortgages is similar to standard mortgages, with the added requirement of a minimum Building Energy Rating (BER) of B3 or higher. Green Mortgages are available to:

  • First-Time Buyers
  • Switchers
  • Home Movers
  • Self-Builds

Upgrading your home to increase its BER rating to B3 or above may also make you eligible for a Green Rate Mortgage from your existing lender. For information on grants to improve your home’s energy performance, visit:

Understanding Building Energy Ratings (BER)

A BER rates a house’s energy efficiency on an A-G scale, with A being the most efficient and G being the least. A-rated homes use less fuel, as they conserve heat more effectively, resulting in lower energy bills and a reduced environmental impact. 

A BER Certificate is required when selling or renting a property and is valid for ten years unless changes affecting energy performance are made. Find a local BER assessor through the SEAI National Register of BER Assessors:

Pros and Cons of Green Mortgages

Like standard mortgages, Green Mortgages have both advantages and disadvantages:


  • Encourages energy-efficient home purchases, reducing monthly bills
  • Rewards homeowners who retrofit their home for a higher BER
  • Offers potentially lower interest rates than standard mortgages
  • Helps reduce your carbon footprint
  • Homes with good BERs may sell faster and be more appealing


  • Cashback and other offers may not be available
  • Retrofitting to meet BER requirements can be expensive
  • Limited fixing options compared to standard mortgages
  • Not always the cheapest option; seek advice from a Mortgage Advisor

Are Green Mortgages Environmentally Friendly?

While Green Mortgages offer lower interest rates for energy-efficient homes, they don’t directly contribute to environmental initiatives. However, they do incentivize energy-efficient home purchases and upgrades, reducing your carbon footprint and energy consumption.
