Wollongong sits in NatHERS Climate Zone 56 — a temperate coastal climate moderated by sea breezes. However, suburbs nestled against the escarpment (Figtree, Unanderra) experience warmer summers and cooler winters than the coastal strip. Homes near the beach benefit from natural ventilation but face salt spray and corrosion challenges.
A NatHERS certificate in Wollongong typically costs $350–$550 for existing homes. Wollongong assessors often also service Shellharbour, Kiama, and the southern Illawarra, so availability is generally good.
NSW requires BASIX certificates for new developments, including homes in the Wollongong LGA. For existing homes in the Illawarra, a NatHERS rating helps identify energy savings — particularly valuable given the mix of older fibro and brick homes in suburbs like Warrawong, Dapto, and Berkeley.
Wollongong falls within the New South Wales building regulations, which require new homes to achieve a minimum NatHERS star rating. Our certified assessors are familiar with local council requirements and can guide you through the process. Energy ratings are also increasingly important for property sales and rentals in Wollongong.
Older fibro homes common in the southern Illawarra (Dapto, Albion Park, Berkeley) often have no wall insulation and single-glazed windows. A NatHERS assessment can identify whether adding wall insulation or upgrading windows provides the best return on investment before you commit to expensive renovations.
Use the search above to find a local accredited NatHERS assessor in Wollongong. All listed assessors are certified by an Assessor Accrediting Organisation (AAO) and service Wollongong and surrounding suburbs. You can contact them directly — there's no booking fee.

In Wollongong, the terms "NatHERS assessor", "energy assessor", "home energy rater" and "thermal performance assessor" are used interchangeably. NatHERS (Nationwide House Energy Rating Scheme) is the official accreditation — any assessor performing a star rating for compliance or sale must be NatHERS accredited.
For an existing Wollongong home, the on-site inspection typically takes 1–2 hours, with the certificate issued within 3–7 business days. New build assessments from plans can usually be turned around in 5–10 business days.
Mandatory disclosure rules vary by state, but a NatHERS rating is increasingly used as a marketing tool in Wollongong property sales — particularly for energy-efficient homes. The ACT requires disclosure at sale; other states are progressively introducing similar requirements.
