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:

  • 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 ‘energy-efficient’ offers
  • how much you need and the term of loan

For details, see our Loans for energy-efficient purchases guide.

You may be eligible for the Green Home Offer if your home meets the GBCA Green Home Standard, or has 7 stars or greater under the Nationwide House Energy Rating Scheme, or already has eligible small-scale renewables installed. 

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.

  • A CommBank Green Loan may be more suitable for you if you’re after a loan for small scale renewables (e.g. solar panels) and you have total CommBank home loan balance/s of $150,000 or more (not including any redraw balances, construction loans which are not yet fully funded, loans for bridging purposes, Equity Unlock for Seniors loan, Viridian Line of Credit or a new CommBank Green Loan). 
  • You may be eligible for InstalPay, our interest-free loan available at checkout via approved CommBank merchant UPowr, if you’re an existing CommBank customer looking for an interest-free loan to purchase solar panels and/or batteries.
  • A CommBank Personal Loan for energy-efficient purchases may not be right for you if the features listed above aren’t suitable and don’t meet your needs

In addition to our standard loan application documents (evidence of income, expenses, assets and liabilities etc.), there are other specific documents you’ll need to provide to be eligible for an energy-efficient discount:

  • Purchase amount (the loan amount must not exceed the purchase amount)
  • Retailer and/or installer details; and
  • Itemised system* details for the eligible energy-efficient product(s).

We’ll check the documentation you provide us and apply the energy-efficient discount to your loan once we’re satisfied you’ve met the above conditions. If we’re not satisfied, our standard pricing (without any discount) will apply should you wish to proceed with your loan.

  • You’re unable to increase or refinance an existing CommBank home energy loan.
  • If you’ve already bought and installed eligible energy-efficient products, you can't use a CommBank Personal Loan for energy-efficient purposes to recoup your out-of-pocket costs or to refinance an existing loan.

    • Interest rates range from 7.00%3 p.a. to 8.49% p.a. (comparison rate from 8.41% p.a. to 9.88% p.a.). The estimated total amount payable including fees is between $36,792 and $38,071

    Unsecured Variable Rate Personal Loan interest rate ranges (with energy-efficient discount applied) are set out below. Comparison rates and examples are based on a $30,000 unsecured variable rate loan over 5 years:

    • Interest rates range from 7.50%3 p.a. to 8.99% p.a. (comparison rate from 8.90% p.a. to 10.38% p.a.). The estimated total amount payable including fees is between $37,218 and $38,506

    * System size noted on the invoice/quote must be equal to or greater than our requirements as set out under ‘Eligible energy-efficient products’.

    ^ You may be eligible for same-day funding if you’re approved, accept your contract and complete verification by 4pm Monday to Friday (Sydney/Melbourne time). Subject to credit checks and assessment of your financial situation. Unavailable if an application is incomplete or needs to be referred for a more detailed review by a lending specialist, or if required documentation isn’t provided, and subject to system availability.

    1 Interest rates at the lower end of our range, for example 7.00%/7.50% p.a. (comparison rate 8.41%/8.90% p.a.), may be offered to low risk customers with an excellent credit history.

    2 Comparison rates are calculated based on an unsecured loan of $30,000 and a secured loan of $30,000, over a term of five years. WARNING: Comparison rate is true only for examples given and may not include all fees and charges. Different terms, fees or other loan amounts might result in a different comparison rate.

    3 Additional repayments made on a fixed rate and secured personal loan are not available to be redrawn. An early repayment adjustment is charged if loan is fully repaid with 12 or more months remaining on loan term, and we reasonably estimate we will incur a loss or administrative cost. View the Personal Loan Terms and Conditions.

    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. You can find out more about how your credit score is calculated and tips for improving your credit score at our Credit Score Information Hub.
