How much does a Healthy Homes assessment cost, and is it worth it?

Independent Healthy Homes assessments are typically priced in the low hundreds of dollars per property, varying with region and property size, and usually produce a written report against each of the five standards. Whether that is money well spent depends on what you need the assessment to be: information, evidence, or confidence.

When the free route is enough

The official tools are public: the heating assessment tool, the per-standard guidance on tenancy.govt.nz, and nothing in the law requires a paid assessor. A hands-on landlord with safe access to the ceiling and subfloor can establish the facts personally and photograph them, which is both free and, done properly, produces the same class of evidence a compliance statement needs.

When paying earns its keep

• You need a written professional opinion, especially to support a practicability exemption.
• Access is unsafe or beyond you, subfloors genuinely are.
• You are signing a compliance statement and want independent eyes on it first.
• Portfolio scale: a few hundred dollars per property to de-risk several statements at once is cheap certainty.

Either way, keep the output

An assessment's value is mostly in its afterlife: the report, or your own photos and tool results, filed against the property, feeding every future statement and answering questions years later. An assessment that lives in an email attachment from 2024 has stopped being evidence and started being archaeology. File it once, per standard, where the next question will find it.
