Why Consider the ING Green Upgrade Loan?

 

The ING Green Upgrade Loan is the standout green loan in Australia right now. With a fixed interest rate of just 3.74% p.a. (5.16% comparison rate), it offers the lowest pricing of any green loan currently available from a major bank. That means you get five years of repayment certainty, with none of the stress that comes with rising rates or hidden fees.

What makes this offer truly market-leading is the combination of ING’s market-leading variable home loan rates and the ultra-low fixed rate on the Green Upgrade Loan itself. When you refinance your mortgage to ING, you may also be eligible for $1,500 cashback—a generous boost to help cover the cost of your upgrades. Borrow between $5,000 and $50,000 to fund high-impact improvements like solar panels, battery storage, reverse-cycle air conditioning, and induction cooking, and take advantage of a green finance package that leads the market on both price and value.

For homeowners looking to make the switch, this is the best-value green loan in the market today—and a smart way to future-proof your home from rising energy costs while maximising savings on your home loan.
