Top Green Home Loans in Australia

Tree canopy view from the ground

Residential buildings are responsible for nearly a quarter of overall energy use and more than 10% of total carbon emissions in Australia, as reported by the Australian Government. With the increasing concern about the climate crisis, it’s no wonder people are looking for greener options when it comes to building and owning homes. 

Energy use is an important metric for sustainability: just over 83% of Australian homes do not meet the 7 star Nationwide House Energy Rating Scheme (NatHERS) rating that deems a property green. Furthermore, the 2023 CSIRO data reports that only 21% of new homes built so far this year received the goal of a 7-star rating or higher.

What is a green home loan?

A green home loan is a type of loan that encourages borrowers to buy or build their future homes in an environmentally friendly way. These loans usually offer discounted interest rates for homes that pass a form of eco-friendly certification.

 To qualify for this green home loan, your future home should typically have at least one of these qualifications**:

  • A 7 stars or higher rating under NatHERS.
  • A Residential Efficiency Scorecard with a rating of 7 stars or more (excludes the impact of installed/installing rooftop solar).
  • Passive House Certification.
  • Green Star, Design & As Built score of 8 points or more on the credit ‘15 Greenhouse Gas Emissions.’

**Specific qualification criteria will differ from lender to lender.

What is the difference between a green loan and regular home loan?

The main difference between a green home loan and a regular home loan is that a green loan is exclusive to homes that qualify certain environmentally friendly criteria put forth by the lender.

Should I get a green home loan?

Getting a green home loan is great if you are environmentally cautious and want to do your part in the fight against the climate crisis.

However, even though lenders offer interest rate discounts for green homes, it doesn’t mean they are the cheapest home loan option. If your priority is finding the most affordable home loan out there, then a green home loan might not be your best option.

When comparing home loans you should consider things like:

  • Interest rates
  • Home loan fees
  • Money-saving features like an offset account or being able to make extra repayments

But if you are already considering investing in an eco-friendly and energy efficient home, getting a green home loan might be a good choice.
