This comprehensive guide will teach you everything you need to know about green loans, including what they are and how they can be used, the different types of green loans available and their unique benefits, plus essential information about eligibility requirements and the application process

What Are Green Loans?

A green loan is financing specifically designed for purchasing products and services that benefit the environment and reduce your home's energy consumption. Unlike regular loans, green loans offer preferential rates and terms because they support environmentally beneficial upgrades that also improve your home's value and reduce ongoing costs.

Why are they called "green"? The name comes from their connection to nature and environmental benefits – just like trees, grass, and forests. Green loans earned this name organically as they became recognised as a specific type of lower-cost financing designed to help homeowners purchase products that are great for both their homes and the environment.

What can Green Loans be used for?

Green loans can finance a comprehensive range of energy-efficient technologies and home improvements that reduce your environmental impact while cutting your energy costs. These loans are specifically designed to support the purchase and installation of products that help homeowners transition to cleaner, more efficient energy systems and create more comfortable, sustainable living environments.

From solar energy systems and efficient appliances to smart home technologies, green loans make it possible to transform your home without the burden of large upfront costs. Each upgrade not only contributes to environmental sustainability but also delivers ongoing financial benefits through reduced energy bills and increased property value – it's a great way to save money on your energy bills, increase the value of your home, and make it more comfortable to live in.

Green Loan Types

When it comes to financing your energy upgrades, you've got several green loan options to choose from – and the right one depends on your situation, goals, and what feels most comfortable for you. Some people prefer a personal loan to finance their home energy upgrade, while others may want to refinance their mortgage to fund upgrades and find a better deal.


The good news is that more and more Australian banks are rewarding customers for making their homes more energy efficient. This means you're likely to find an option that works for your circumstances, whether you're after the lowest monthly payments, the fastest approval, or something in between.
Let's break down the four main types of green loans available, so you can get a feel for what might work best for your situation:

Green Home Loans and Mortgages

Perfect for homeowners looking to refinance or purchase while upgrading their property's energy efficiency. These loans offer discounted mortgage rates for homes that meet minimum energy efficiency standards or undergo qualifying improvements. This is a great way to save on your energy bill and on your mortgage. Some banks even offer up to $1,500 cashback when you refinance and upgrade with them.

Secured Green Personal Loans

If you have a mortgage, chances are your bank offers very low interest rates to finance your upgrades. Interest rates are lower than the mortgage rate, so super attractive.


Think of a secured green personal loan as almost like a separate mortgage sub-account – it's secured against your property just like your main home loan, but it's completely separate with its own repayment schedule and terms. This means you get the benefit of low interest rates (because the bank has the security of your property) without having to touch your existing mortgage arrangements.

Benefits and Savings Potential

Here's where green loans really shine –they're not just good for the planet, they're genuinely good for your wallet too. The main reason people love green loans is that they're often significantly cheaper than regular personal loans. We're talking lower interest rates, reduced fees, and sometimes even waived establishment costs. When you add it all up, you're paying back substantially less than you would with a standard loan.

But here's the really exciting part – the upgrades you're financing with these loans are smart investments that keep paying you back long after you've made the purchase. When you install solar panels, batteries, heat pump hot water systems, induction cooktops, or reverse cycle air conditioning, you're not just buying products – you're investing in ongoing energy bill reductions that can last for decades.

The benefits go way beyond just saving money on electricity though. These upgrades make your home more valuable – recent data shows energy-efficient homes sell for an average of $118,000 more than standard properties – safer to live in, and often much more comfortable year-round. Plus, if you're thinking about refinancing down the track, having an energy-efficient home can actually help you qualify for better mortgage rates too.

The bottom line? You get the best of both worlds – affordable financing that makes the upgrades possible, plus years of ongoing savings and increased home value that more than pay for themselves.

Avoiding Common Pitfalls

Interest-Free Loan Traps

Interest-free loans might sound too good to be true – and often they are. While these loans can make getting your upgrade started much easier with no upfront costs, they frequently come with hidden surprises that can make them more expensive than traditional green loans.

The main catch is that lenders charge installers a hefty upfront fee (called a merchant fee) to offer these interest-free deals. This fee – which can be as high as 35% of your quote – is typically built into the purchase price you pay. So while you're not paying
interest, you might be paying significantly more for the actual products and
installation.

Green Homes Australia and 28Watt don't offer Interest-free options because normal green loans are actually cheaper overall and much more transparent. We believe in honest pricing where you can see exactly what you're paying for.

Qualification Myths

Common misconceptions that can delay or derail applications:

  • "My bank doesn't offer green loans" Many people don't realize their bank offers cheap green finance options. 28Watt will ensure you find the best loan available.
  • "Green loan qualification is too complex" – ALL upgrades with Green Homes Australia automatically meet requirements, and 28Watt are the experts who handle all the complexity for you.
  • "You can only get green loans if you have a mortgage" – Not true! Refer to the unsecured personal loan options available to all homeowners.
