Mercury Cosy - GreenSide Energy Solutions

Mercury Cosy

Making your home healthy has never been easier! 

We’ve partnered with Mercury to provide a tool that performs an online assessment of your home, and recommend products to make your home warmer, drier, healthier and more energy efficient.

Free Home Assessments for Owner-Occupiers

Designed to take the hassle out of making your home healthier, the free Cosy Home Tool gives you a breakdown of how you can make your home warmer and healthier, and an estimate of how much it will cost.

Healthy Homes for Less

The assessment also shows you a cost estimate, and lets you know if you are eligible for the Warmer Kiwi Homes 90% subsidy on insulation and heating. We’ve also got some exclusive discounts on these products of up to 20%.

You can also get an exclusive Mercury Cosy discount on any GreenSide services you purchase.
