Green mortgages explained

A green mortgage could save you money if you have an energy-efficient home. Here’s all you need to know about green mortgages in Ireland and how to pick the best one.

What is a green mortgage?

It’s a type of mortgage which offers lower interest rates or a discount for:

  • house buyers who purchase an energy-efficient home
  • homeowners who live in energy-efficient homes

Energy-efficient homes are more environmentally friendly, and need less energy to heat and run. They will save money on energy bills over time.

The mortgage loan isn’t ‘green’ itself, and the mortgage lenders are not necessarily more ethical. The positive environmental impact comes from your home using less energy and having a reduced carbon footprint.

How does a green mortgage work?

Green mortgages in Ireland work the same way as a standard mortgage - you’ll borrow a large sum of money to buy a property and make monthly payments with interest to repay the loan. The main features are:

  • You get a discount off the lender’s standard rate so your mortgage is cheaper
  • Savings you make are mostly due to the discounted interest rate
  • Mortgage cashback may also be on offer at drawdown
  • To qualify, the house you’re buying, building or adapting will need to have a Building Energy Rating (BER) of B3 or higher.

What is a Building Energy Rating (BER)?

A Building Energy Rating (BER) shows your home’s energy performance and grades your home’s energy efficiency on a scale of A-G. Things to note:

  • A-rated homes are the most energy-efficient and G-rated homes are the least
  • The higher your BER, the less energy you use. For instance, an A-rated house conserves heat better so you’ll use less fuel to keep it warm.
  • A BER certificate is now required for most homes for sale or rent in Ireland
  • BER details must be included in advertisements when a home is on the market. Since 2007 all new build homes are required to have a BER certificate.

In summary, A-rated homes will benefit from lower energy bills and leave a smaller carbon footprint while G-rated homes will attract high energy bills and are less environmentally friendly.

Are you eligible for a green mortgage?

The eligibility requirements for a green mortgage are the same as for a standard mortgage application, such as being an Irish resident over 18 years, but to qualify for a green mortgage there are three pathways.

You may be entitled to a green mortgage if you are:

  1. Buying a home with a BER between B3 and A1
  2. Adapting a home so it has a BER between B3 and A1
  3. Building a house with a BER between B3 to A1

Green Mortgages FAQs

How is my BER calculated?

A BER is based on the calculated energy performance and associated carbon dioxide emissions from room and water heating, ventilation and lighting under standardised conditions.

Factors that are used in the calculation are the house dimensions and orientation, types of windows, insulation and heating and hot water efficiency.

Although a BER takes into account how many people live at the property, it doesn’t include electricity used for purposes other than heating, lighting, pumps and fans.

Can I get a loan to make my home more energy efficient?

Yes, several Irish banks offer Green personal loans and homeowner loans designed for improving your home’s energy efficiency. You’ll just need to provide evidence of work and grants obtained to benefit from discounted loan rates.

Are there any grants available to increase my BER Rating?

Yes, the SEAI offers a range of Home Energy Grants for homeowners and those undertaking a self-build. Home Energy Grants are available for the following:

  • Insulation - up to €8,000
  • Heat Pump Systems - up to €6,500
  • Heating Controls -up to €700
  • Solar Water Heating - up to €1,200
