Help & support
To qualify for the energy-efficient discount, you must use your personal loan to buy or install eligible products listed below. Solar panels, battery packs and inverters (if applicable) must be purchased from a New Energy Tech approved seller. The installer must be accredited with Solar Accreditation Australia.
Yes, to help you decide which loan type might be most suitable, see our Loans for energy-efficient purchases guide.
No, you can’t use a Personal Loan for energy-efficient purchases to recoup costs for products already installed. However, it's available for upgrading your existing eligible products or purchasing new products.
For example, if you have existing energy-efficient purchases 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 energy-efficient purchases. 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.
When trying to decide on the right product, consider:

An excellent credit history is determined by, among other things, paying your bills and making loan repayments on or ahead of time, being disciplined with your credit applications, and not overextending yourself financially.
Actions which can negatively impact your credit history include missing bill or loan repayments, defaulting on your credit facility, or making a large number of credit applications in a short period of time.
