A NatHERS certificate in Sydney typically costs $350–$600 for existing homes and $200–$400 for new builds. Western Sydney properties with complex designs may cost more. All assessors listed hold current NatHERS accreditation.
NSW requires a BASIX certificate for all new residential developments, which includes energy efficiency targets. For existing homes, a NatHERS energy rating is increasingly required for property sales disclosures and renovation approvals. Sydney councils are progressively adopting energy rating requirements — check with your local council for specific obligations.
Sydney 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 Sydney.
Western Sydney homes (Penrith, Blacktown, Liverpool) are in a hotter climate zone than the coast. If you're renovating, prioritise shading, insulation, and efficient cooling — these areas can experience 5–10°C hotter summers than Bondi or Manly. A NatHERS assessment will quantify exactly how much you'll save.
Use the search above to find a local accredited NatHERS assessor in Sydney. All listed assessors are certified by an Assessor Accrediting Organisation (AAO) and service Sydney and surrounding suburbs. You can contact them directly — there's no booking fee.

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