Gateway Bank Green Plus Home Loan

The Gateway Bank Green Plus Home Loan rewards homeowners for making their homes more energy efficient. The Green Plus Home Loan is easily accessible if you've installed an appropriately sized solar system for your home. Gateway Bank requires a 7-star Residential Efficiency Scorecard to be provided along with your credit application to qualify for the discounted mortgage rate, which can be provided free of charge if refinancing with 28Watt.

With a 5.60% p.a. variable interest rate, this loan offers a great discount of around 0.3% on widely available market rates. When you look at the average Australian home loan of $680,000, that could mean a saving of almost $50,000 over a full 30-year term.

Why We Love This Home Loan

 

The Gateway Bank Green Plus Home Loan offers a fresh, practical approach to a green home loan. The requirements are made simple, rewarding homeowners who install solar panels and achieve a 7-star Residential Efficiency Scorecard with a lower mortgage rate - at least 0.25% p.a. off the standard Premium Package rate. On an average-sized mortgage, that adds up to thousands in savings over the life of your loan!

By installing solar panels, most homes can easily meet the 7-star Scorecard threshold, unlocking access to this discounted, award-winning home loan. It’s a smart move: your home becomes more energy efficient, cheaper to run, and cheaper to own.

While scorecards can sound complicated or expensive, they aren't! With 28Watt’s Free Home Assessment, we show you that meeting the requirements is quite simple. We'll guide you through installing the right-sized solar system not only to achieve the required scorecard result, but also to help lower your electricity bills for good. Plus, we'll cover the cost of your scorecard assessment! (Normally $500).

Residential Efficiency Scorecard (RES) - The Easiest Pathway

 

The simplest way to qualify for the Gateway Bank Green Plus Home Loan is through a 7-star Residential Efficiency Scorecard. Unlike other methods that focus purely on building materials or design standards, the Scorecard looks at the actual cost to run your home. This means if you've installed solar panels (or plan to), you generally will already qualify. Don't have solar or are unable to install it? There are other ways to boost your home's Scorecard rating quickly and affordably. With a free 28Watt Home Assessment and Scorecard included, this is the fastest, most accessible way to unlock your green solar home loan benefits and start saving.

Nationwide House Energy Rating Scheme (NatHERS)

 

The Nationwide House Energy Rating Scheme (NatHERS) is more complex for existing homes. NatHERS ratings evaluate a home's thermal design, including insulation, window orientation, and ventilation. While perfect for new builds, it's a more complicated option for existing homes, often requiring costly renovations. For homeowners looking for a quick and cost-effective way to qualify for a green home loan, NatHERS can be a challenging and expensive pathway.

Green Building Council of Australia (GBCA) Green Star Certification

 

Best for new projects - GBCA’s Green Star certification measures a building’s environmental performance across energy, water, materials, and emissions. It's a prestigious certification typically suited to large-scale developments or major renovations. Achieving Green Star certification involves substantial documentation and cost, making it less practical for everyday homeowners aiming to quickly qualify for a green solar home loan.

Hot tip!

While many other lenders require installations must be carried out by accredited installers, Gateway Bank are a bit more flexible. So if you're worried that your solar installation may not have met the Bank's criteria - don't worry! Reach out, and we'll be able to help. 

To qualify for the Green Plus Home Loan:

 

You must:

  • Be buying, refinancing, or renovating an eligible home
  • Have a 7-star Resedential Efficiency Scorecard or NatHERS rating
  • Have a Green Building Council of Australia (GBCA) Green Star Designed or Certified home.
  • Provide certification from an accredited assessor as evidence of meeting the requirements.

28Watt's Takeaway

 

The Gateway Bank Green Plus Home Loan has taken the crown as Australia’s best green home loan now that Bank Australia’s Renovate loan is on pause. Offering a 5.60% p.a. variable rate, it undercuts mainstream variable loans by roughly 0.30% and, crucially, the discount lasts for the full 30-year term rather than a short honeymoon period. On an average mortgage of $680,000, that pricing edge alone can deliver interest savings of around $50,000 across the life of the loan.

Qualifying is refreshingly simple. Install a correctly sized solar system, secure a 7-star Residential Efficiency Scorecard, and you unlock the market-leading rate with no need for costly renovations or complex certifications. Most homes that go solar already meet the Scorecard threshold, making this loan accessible for everyday homeowners looking to refinance or purchase.

Pair the ongoing mortgage discount with the lower energy bills that flow from solar power and you create a powerful double saving. Household cash flow improves immediately, while the property gains long-term energy efficiency and resale appeal.

Book a free 28Watt Home Assessment and we will cover the cost of your Scorecard, map out the upgrades that maximise savings, and connect you with trusted installers. Secure Australia’s leading green variable rate, cut your power bills, and future-proof your home in one straightforward journey with 28Watt.
