Accredited Assessors negotiate their own fees to perform NABERSNZ Certified Rating assessments
Assessments should cost between $2,000 to $6,000 depending on the type of rating, size and complexity of the building, and availability of data.
As with any professional service, you should get several quotes and compare suppliers before engaging an assessor.
In general, the cost of second and subsequent ratings should be lower, because much of the preparatory work will be done for the first rating.
Direct funding for Certified Ratings is not available, but much of the work you can do to improve your rating can attract funding.
