Financial institutions have innovated to offer a range of residential energy efficiency finance products for owner-occupiers and residential investors. Analysis of the residential energy efficiency finance products offered by the major banks demonstrates that households do have a range of energy efficiency finance products to select from. The common features of products are individual pricing the risk of loans, interest rates generally higher than standard variable housing loan rate and loan repayments shorter than housing loan repayment terms. 

This research examined the strengths and limitations of governance in financing and delivering home energy upgrades in existing homes in Australia. The research:

  • analysed how these upgrades are typically financed, reviewing the energy-efficiency financing products offered by major banks, focusing on interest rates and repayment terms. 
  • looked at alternative mechanisms, such as income-contingent loans and property-linked finance
  • examined how behavioural finance affects household decisions and the equity implications of current products and incentives.

Research findings highlight where finance arrangements support home energy upgrades and where opportunities for reform remain. Alternative financing, such as income-contingent loans and property-linked finance, can reach households that existing products do not serve well. 

Led by Centre for Sustainable Development Reform (CSDR), this research is part of the Energy Upgrades for Australian Homes (EUAH), this project co-funded by UNSW & RACE for 2030.

EUAH is a national collaboration across five universities and CSIRO. The overall objective of EUAH is to develop the tools, evidence, and guidance necessary to enable councils and community organisations to deliver tailored, scalable, and effective energy upgrades for Australian homes.
