Insulation installers

Use a qualified professional to install or upgrade your insulation - even small installation faults can compromise its performance.

Choosing an insulation installer

When choosing an insulation installer, be sure to ask a few key questions.

  • Are they familiar with the New Zealand Standard for installing insulation in residential buildings (Standard NZS 4246:2016)?
  • What level of experience do they have installing insulation in New Zealand homes?

Shop around and get a few quotes. Make sure the quotes include the same product types, so you’re comparing like with like. You should also ask if there are any extra costs, for example removing material from the ceiling or underfloor space, or any extra labour costs. Some providers also offer their own subsidies or special offers so this is something worth checking with them.

Certified insulation installers

The Insulation Association of New Zealand (IOANZ) has a list of insulation installers that have gone through the Association's training for installing ceiling and underfloor insulation.

Contact us with questions or concerns

If you have questions or concerns about the insulation or service provided under an EECA project, you should contact your service provider first to see if they can resolve your issue. You can ask for your post installation audit, which the company signs to say your home has been insulated to required standards. If you still aren’t satisfied, or you’d like an independent opinion, fill out our concerns form.
