Can I install these services myself?

What is an Installer?

An Installer is a company that as part of their usual business, installs insulation, heat pumps, ventilation, double glazing and/or solar power systems. The Installers’ quote or invoice must not more than 30 days old.

What type of heat pump can I get installed?

You can install a fixed single-split heat pump system, multi-split heat pump system or a ducted heat pump system for heating your home. These services must be installed by an Installer.

Other types of heat pumps, such as portable heat pumps and heat pump water heaters, are not eligible. You can also use the Rightware tool by Energy Wise to find energy efficient heat pumps.

How do I know what my house needs?

The HomeFit Online Checklist is a great tool to help identify areas where your home could do with some work to make it warmer, drier and safer. Developed by the NZ Green Building Council, HomeFit offers a list of local installers to do the work based on the assessment report, and even helps landlords check if rental properties meet standards set by the Residential Tenancies Act.
