Wellington Home Energy Savers Assessment

Get a personalised at-home assessment and advice on practical solutions to improve your home's energy performance. 

One of our qualified Home Performance Advisors will visit your home to assess in-depth everything that affects the health and energy efficiency of your home. This includes insulation, heating, ventilation, draughts, moisture issues, energy and water use. It takes about two hours, you get a personalised and detailed action plan and subsidised water and energy-saving measures on the day. Free for Wellington city ratepayers, $120 for ratepayers elsewhere. 

Who can get a Home Energy Saver Assessment? 

It's free for Wellington city ratepayers. Anyone else in the Wellington region can book the assessment for a subsidised rate of $250 (RRP $350). 

What do you assess? 

Everything that impacts how energy efficient your home is, and what you might be able to do to make better, warmer and drier. Our qualified Home Performance Advisors look at your levels of insulation, the energy efficiency of your lighting, your ventilation, your heating sources, moisture issues, water use, energy use and draughts. It's a whole-house approach based on building science and ecodesign principles. 

How long does it take? 

About two hours. 

Why does it take that long? 

It's pretty in-depth! We also give advice and tips as we go so you are able to start creating a more energy-efficient home right away. 

Then what? 

Then we give you a personalised action plan that will help you create a more energy-efficient home. It will help you to prioritise changes so you're making changes with the biggest impact first. We'll also give you some product recommendations and quotes - because what good is advice without solutions?  We only suggest products that are right for your home, our environment, and will maximise energy efficiency.

There can be a wait time of up to four weeks for a home energy saver assessment, so we recommend booking in advance.
