This week, Commonwealth Bank became the first Big Four bank to introduce a green offer home loan, which rewards new and existing customers for reducing their dwellings’ environmental footprint.

The Green Home Offer promises lower interest rates for customers whose homes meet certain conditions, such as having a certified Green Star Home, or satisfying the following criteria:

  • Nationwide House Energy Rating Scheme (NatHERS) = 7 stars or greater.
  • Electric cooking/heating instead of gas
  • Solar panels producing minimum energy outputs*. 

*Minimum energy requirements for solar size relative to size of the house: 

  • Up to 150m2 = 5.5kWe
  • 150 - 250m2 = 7.5kWe
  • 250m2+ = 10kWe

Customers whose eco-friendly homes make the cut could enjoy a standard variable late as low as 2.99% p.a. (3.44% p.a. comparison rate*) – one of the lowest available options tracked by Mozo. 

This will be for owner-occupiers making P&I repayments with a Wealth Package mortgage and a deposit of at least 20%.

Building a green home for the future

Smaller lenders have offered green home loans to environmentally conscious Aussies for a while now. However, this launch marks a critical shift in the big bank’s attitude towards sustainability and climate change action.

“We want to reward new and existing customers [...] investing in homes that are efficient, comfortable, and healthier for them and the environment,” said CommBank’s executive general manager of home buying, Dr. Michael Baumann.

“We expect all residential homes to be built to these standards over the coming years as we move towards a net zero future.”

CommBank made the announcement in partnership with the Green Building Council of Australia (GBCA), who lauded the bank’s new future-minded mission.

By raising awareness and providing ways to ease both living costs and environmental impact, CommBank sets a new precedent in green finance for major Australian banks.
