Green Loan

Updated 12 Mar 2026Content was accurate at the time of publication

What is a green loan?

A green loan is a purpose-specific financing product designed to fund low-emissions, energy-efficiency or renewable energy upgrades. Unlike a general personal loan, a green loan is marketed for "green" projects — such as solar PV, battery storage, heat pumps or insulation — and may include lender verification or preferential terms tied to environmental outcomes. Lenders create green loan products to support sustainability goals, attract customers looking to reduce energy costs, or participate in co-financing programs like the Clean Energy Finance Corporation's Household Energy Upgrades Fund (HEUF).

A genuine green loan will specify permitted uses, how proceeds must be spent, and any verification the lender requires. Be cautious of ambiguous marketing — a few key questions to the lender (request written confirmation of eligible uses, ask for product specifications, and seek third-party accreditation) can help verify genuine green claims versus standard credit options with a green label.

What you can use a green loan for

Green loans usually list eligible works or equipment. Typical permitted uses include:

Solar photovoltaic (PV) systems (panels, inverters)
Battery storage systems and hybrid solar + battery installs
Electric vehicle (EV) chargers and related electrical upgrades
Heat pumps (space heating, hot water) and energy-efficient HVAC
Insulation, draught-proofing and efficient windows/doors
LED lighting upgrades and smart controls
Certified energy-efficient appliances (e.g., refrigerators, washers)
Building energy assessments and installation labour directly related to listed upgrades

Example scenarios illustrate common project sizes. A household wishing to install a 6.6 kW solar PV system plus a 10 kWh battery might use a green loan to cover equipment and installation costs (typical project cost: $12,000–$15,000, depending on specifications). A small café replacing an old air-conditioning system with a high-efficiency heat pump and LED lighting could finance the upgrade with a green loan that accepts commercial energy upgrades.

When you read product terms, check whether the lender accepts mixed projects (e.g., solar + insulation) and whether a single loan can cover both equipment and installation.

Types of green loan products

Green loans come in several forms. Understanding the product type helps you match finance to project size and risk tolerance.

Unsecured green personal loans

Short-to-medium term, no security required. Typical for small projects (up to $10k–$10k). Repayments fixed or variable, higher interest than secured options. See a general primer on personal loan.

Secured loans / home loan top-ups / green mortgages

Larger amounts can be added to an existing mortgage or structured as a secured green mortgage with lower interest rates and longer terms. This option suits major retrofits or whole-home energy upgrades.

Vendor or point-of-sale finance

Finance offered by installers or specialist providers at the time of purchase (similar to vendor finance). These often have quick approvals and tailored terms for specific products. See vendor finance for mechanics.

Government or co-financed schemes

Programs backed or co-funded by organisations such as the CEFC HEUF may provide discounted rates or blended finance structures for eligible households and small businesses. Details available from the Clean Energy Finance Corporation.

Green-tagged products from mainstream lenders

Some lenders label a home improvement or personal loan as a "green loan" and require invoices or product specs to verify eligible spending.

For smaller, consumer-level projects you may also compare a green personal loan with other consumer options such as a standard personal loan or an unsecured line of credit.

Key features & costs to compare

When evaluating green loan offers, compare the following features carefully.

Interest rate type and range

Fixed vs variable rates. Rates indicative as at January 2026. Typical ranges (indicative only):

Unsecured green personal loans: 7%–16% p.a.
Secured green mortgages / home loan top-ups: 3%–6% p.a. (variable)
Vendor/point-of-sale finance: 6%–14% p.a. (promotional offers may vary)
Government/co-financed schemes: 2%–6% p.a. (where available)

Fees

Establishment/application fees, ongoing account fees, late payment fees, early repayment or break costs (for fixed secured facilities). Check if government schemes waive fees or require co-contributions.

Term and maximum amount

Terms range from 1–7 years for unsecured loans, to 10–30 years for secured mortgage top-ups. Max amounts depend on product type and security.

Security required

Unsecured loans: no security. Secured options: mortgage, charge over property, or PPSR registration for large equipment.

Verification and permitted use controls

Some green loans require quotes, product model numbers, installer invoices or energy assessment reports before drawdown or as a post-drawdown compliance step.

Credit score and affordability impact

Loan serviceability assessments follow responsible lending obligations under the National Consumer Credit Protection Act. Applications affect credit enquiries and may be reported to credit bureaus.

Indicative APRs and comparison metrics

Compare the Annual Percentage Rate (APR) or Comparison Rate where available to capture both interest and fees.

Repayment flexibility

Grace periods, redraw, repayment holidays and offset features vary by product.

Product / Option	Typical max amount	Typical term	Security required	Indicative APR / rate range	Typical fees	Best for	Notes
Green loan (unsecured)	$30k–$50k	1–7 yrs	No	7%–16% p.a.	Establishment, possibly ongoing	Small to medium home upgrades	Quick approval; may require invoices
Green mortgage / top-up	$50k–$300k+	5–30 yrs	Mortgage	3%–6% p.a.	Mortgage fees, valuation, discharge	Whole-home retrofits, large solar + battery	Lower rates but security risk
Personal loan (standard)	$5k–$100k	1–7 yrs	No	6%–20% p.a.	Establishment, ongoing	General consumer spending	Flexible use but not green-verified
Credit card / BNPL	$1k–$50k	Revolving	No	15%–25%+ p.a. (cards)	Annual fee, late fees	Small purchases	Expensive for large projects
Vendor / POS finance	$5k–$100k	1–10 yrs	Sometimes	6%–14% p.a.	Setup fees, promotional terms	Appliance/installer finance	Quick at point of sale; may be restricted to suppliers
Government/co-finance (HEUF style)	Program limits	3–15 yrs	Varies	2%–6% p.a.	Minimal	Eligible households/small businesses	May require eligibility checks and installer accreditation

Use the table to compare total cost and security trade-offs. For many homeowners, a secured green mortgage can offer the lowest rate but increases long-term debt secured against property. Unsecured green loans minimise security but carry higher rates.

Eligibility & documents lenders typically require

Lenders generally assess creditworthiness and project legitimacy. Typical requirements:

Proof of identity (driver's licence, passport)
Proof of income (pay slips, bank statements, tax returns)
Proof of residence and contact details
Detailed quotes/invoices from installers or suppliers specifying equipment, model numbers and installation costs
Energy assessment, product specifications or compliance certificates (required by some green lenders or co-finance programs)
Evidence of ownership/land title if proposing a secured mortgage top-up
Bank statements to demonstrate living expenses and savings
Company financials for small businesses (profit & loss, ABN/ACN, BAS statements)

If applying under a specific program (e.g., CEFC-backed initiative), you may need accredited installer confirmation or additional eligibility paperwork.

How to choose the right green loan

Use this checklist to compare options:

Define the scope and cost of your project (get multiple quotes).
Decide whether a secured or unsecured product suits your risk tolerance.
Compare APRs, fees, and total repayment amounts over comparable terms.
Check permitted uses and verification requirements: will the lender accept your chosen equipment and installer?
Assess interaction with rebates and grants — will a rebate reduce the loan amount or affect eligibility?
Verify the lender's green claim: ask for policy or third-party accreditation where possible.
Confirm penalty and exit costs for early repayment or mortgage redraws.
Read the Product Disclosure Statement or Key Facts Sheet and ASIC guidance on responsible lending.
For complex projects, compare with a mortgage broker or financial adviser.

How green loans interact with government rebates, grants and specialist funds

Green loans can often be used alongside rebates and grant programs, but mechanics vary:

Rebates and discounts typically reduce the capital required, lowering the loan amount.
Some government or CEFC-backed programs co-finance projects; they may require specific installer accreditation, product lists or household income caps.
Point-of-sale schemes may integrate rebates at the time of purchase; check whether the rebate is paid to you or the installer.
Timing matters: confirm whether the lender will disburse funds before or after rebate payment.
For blended finance (part concessional loan + part commercial loan), check security and repayment sequencing.

Consumer protections & regulatory notes

Consumer protections and regulatory frameworks apply to green loans just like other credit products:

Responsible lending obligations and credit assessments are governed by the National Consumer Credit Protection Act and guided by ASIC's RG 209.
Lenders must not misrepresent product benefits. Watch for greenwashing — vague statements without verification.
Check if the lender reports to credit bureaus and how default or late payments are handled.
For mortgage top-ups and secured products, understand the consequences of arrears on secured property.
If a program involves third-party accreditation (e.g., CEFC partner), confirm the accreditation status before relying on concessional rates.
