Westpac Offers Interest-Free Loans For Solar Power

In an effort to address climate change, since the beginning of 2020, Westpac started to offer interest-free loans on solar power systems and a range of products that aim to keep homes healthy and warm.

The loan is only available to both new and existing Westpac home loan customers. Customers can borrow up to $10,000 (interest-free) for up to 5 years.

Other items on the interest-free loan list include insulation, heat pumps, double glazing and ventilation.

Westpac is the first New Zealand bank to be Carbon Zero Certified. They achieved this by reducing their carbon emissions via less air travel, creating energy-efficient offices and enlisting an electric car fleet. The remaining emissions are offset by planting permanent native forests.

Since Westpac started measuring their emissions in 2008, emissions have been reduced by 50% and they aim to reduce them by a further 30% in the near future.

The bank is also giving consideration as to whom can receive loans. Westpac is not currently loaning to coal mining businesses, but are still lending to the gas industry, with the bank hoping to ease these loans back over time.

The requirements for this loan are:

  • To currently have a Westpac home loan, and to meet standard lending criteria.
  • 20% equity in your owner-occupied home, or 30% in your investment property.
