Why does it matter?
Housing standards are being raised across New Zealand to improve the quality of life and public health. Recent law changes set new standards for ceiling and underfloor insulation in rentals, and houses need to be upgraded by July 2019. Statements of Insulation for tenancy agreements have been a legal requirement since July 2016.


Why does it need to be checked? 
Most rentals are uninsulated or not insulated to the new standards on the install, thermal rating, condition, fit and more. A professional assessment will give accurate information on the house's current status and what is required to get up to code.
