Our network of local professionals understands Perth's climate zone requirements and provides fast, accurate, and affordable energy rating services.
Perth is in NatHERS Climate Zone 13 — a Mediterranean climate with hot, dry summers (regularly above 35°C) and mild, wet winters. Cooling is the primary energy concern, but heating is still needed in winter. Homes require good thermal mass, shading, and cross-ventilation to manage Perth's temperature extremes.
A NatHERS certificate in Perth typically costs $350–$600 for existing homes and $220–$420 for new builds. WA's large geographic spread means outer suburbs like Mandurah or Rockingham may have slightly higher costs due to assessor travel.
WA requires energy efficiency assessments under the Building Act 2011 for all new homes. Perth's rapid growth areas (Rockingham, Armadale, Joondalup) are producing thousands of new homes annually that need NatHERS compliance. For existing homes, a rating helps identify how to reduce air conditioning costs — a major concern with WA's rising electricity prices.
Perth falls within the Western Australia 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 Perth.
Perth homes with dark-coloured roofs in suburbs like Armadale and Midland absorb significantly more heat than lighter-coloured alternatives. If you're renovating, consider a light-coloured roof coating — it can improve your NatHERS rating and reduce cooling costs by 15–20%. Your assessor can model the exact impact.
Use the search above to find a local accredited NatHERS assessor in Perth. All listed assessors are certified by an Assessor Accrediting Organisation (AAO) and service Perth and surrounding suburbs. You can contact them directly — there's no booking fee.

In Perth, 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 Perth 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 Perth property sales — particularly for energy-efficient homes. The ACT requires disclosure at sale; other states are progressively introducing similar requirements.
