Financing Your Heat Pump with a Green Loan

A green loan is a type of financing designed specifically to fund environmentally friendly home upgrades. Unlike a standard personal loan, green loans come with favourable terms such as low or zero interest rates, no establishment fees, and flexible repayment options – making them one of the most cost-effective ways to improve your home.

They are offered by most major New Zealand banks as a home loan top-up, typically at rates between 0% and 1% per annum. Every dollar must go toward a qualifying eco-friendly purchase, with heat pumps being one of the most popular eligible items.

These loans are funded by the banks themselves, driven by a combination of corporate sustainability commitments, regulatory pressure to demonstrate green credentials, and sound commercial logic – energy-efficient homes are lower-risk lending assets. The government supports the broader environment through programmes like Warmer Kiwi Homes and the Zero Carbon Act, but the green loan products you’ll find at your bank are private initiatives offered at a discounted rate as a deliberate choice by the lender.
