Yes. If you have an existing Personal Loan and would like to apply for the green discount, you’ll need to apply for a new Personal Loan. Loan increase and refinance applications aren’t eligible for the green discount.

Yes – talk to a CommBank Personal Loan specialist for more information and help in deciding which loan type might be most suitable.

You can’t use a CommBank Personal Loan to recoup costs for products already installed. However, it is available if you wish to upgrade your existing products or are looking to purchase other products on the list of eligible clean energy products.

For example, if you have existing clean energy products and wish to upgrade them by adding more solar panels or a new battery pack, then you may be eligible for a CommBank Personal Loan.

It’s your responsibility to ensure that you’re satisfied with the quality of your eligible clean energy products. If you detect substandard workmanship or materials, or have any disputes with your retailer and/or installer, you should speak with them as soon as possible. Depending on the severity of the matter, you may also need to inform your solicitor.  

Please note: 

  • We won’t become involved with the dispute.  
  • We take no responsibility for the quality and warranty of your eligible clean energy products.  

Don’t attempt any work yourself. Any work must be completed by an approved retailer and/or installer, certified and trained to ensure systems meet industry best practice standards and all relevant Australian Standards (as approved by the Clean Energy Council). 

When trying to decide on the right product, consider:

  • What type of small scale renewables you’re looking to purchase/install;
  • If you have a home loan with CommBank;
  • The interest rates for the various ‘green’ offers;
  • How much you need; and
  • The term of loan.

Talk to a CommBank Personal Loan specialist for more information and help.

You may be eligible for the Green Home Offer. Enjoy a discount on a Standard Variable Rate for Owner Occupied or Investment Home Loans with either Principal & Interest repayments or Interest Only payments for eligible customers on a Wealth Package

  • You may want to review any existing building insurance you hold and consider if the cover is adequate with your new eligible clean energy product(s) installation.
  • Before purchasing and installing clean energy products (excluding cars), consider if you need any additional approvals such as body corporate/strata approvals
