NatHERS Assessor, Sydney
Every new home and major renovation across Greater Sydney needs a NatHERS star rating under NCC 2022. We're accredited assessors delivering accurate ratings with a same-day quote.
NatHERS Assessments for Sydney Projects
Most new homes and major renovations across Sydney now need a minimum 7-star NatHERS rating under NCC 2022, whether you're building in the Inner West, the Northern Beaches, or out toward Penrith and the Hawkesbury. We model your design in accredited software (AccuRate or FirstRate5) against the correct climate data for your specific location and produce the star rating your council and certifier need to see.
Climate matters more than people expect here. Western Sydney suburbs run noticeably hotter through summer than the coastal and inner-city areas, which changes what actually works in a design -- glazing choice, insulation levels and shading that suit a Bondi renovation won't necessarily be the right call for a new build in Penrith. We factor your specific location's climate data into the assessment rather than applying a one-size-fits-all Sydney average.
Who Needs a NatHERS Rating in Sydney?
- New home builds -- required before construction approval, anywhere across Greater Sydney
- Knockdown-rebuilds -- a common project type across established Sydney suburbs with ageing housing stock
- Major renovations and extensions -- where the altered area needs its own thermal assessment
- Townhouse, duplex and apartment developments -- increasingly common across Sydney's middle-ring suburbs, each dwelling assessed individually
How We Deliver It
Send through your floor plans, elevations, window schedule and site details and we'll respond with a same-day quote. Once we have complete plans, most Sydney assessments are turned around within a few business days. If your design falls short of the target rating, we'll recommend the most cost-effective fix for your specific suburb's climate -- often glazing, insulation or shading -- rather than an expensive blanket upgrade.

We're accredited to operate in every Australian state and territory, so whether your project is in Sydney, Melbourne, Brisbane, Perth or regional Australia, you get the same turnaround and the same standard of report. Across 500+ projects, every certificate and report we've issued has been accepted on first submission -- no rejections, no rounds of council back-and-forth eating into your build timeline.
We also work with your design team from early in the process rather than only stepping in once drawings are locked. Catching a compliance issue at concept stage costs a conversation; catching it after a DA is lodged costs a redesign. That's the gap we're built to close.
Frequently Asked Questions
Does my star rating requirement change depending on where in Sydney I'm building?
The minimum rating (typically 7 stars under NCC 2022) is generally consistent, but what it takes to achieve that rating changes with your local climate. Western Sydney's hotter summers usually need different glazing and shading choices than coastal or inner-city Sydney.
Is NatHERS the same as BASIX?
No. NatHERS is a national thermal performance rating for the building fabric; BASIX is a broader NSW-specific assessment covering energy, water and thermal comfort, and is required for every Sydney project alongside or instead of a standalone NatHERS assessment. We handle both together.
Do Sydney apartments and townhouses need individual NatHERS ratings?
Yes -- each dwelling in a multi-unit development typically needs its own rating, even within the same building.
How long does a NatHERS assessment take for a Sydney project?
With complete plans, most assessments are completed within a few business days. Let us know your DA deadline and we'll confirm a turnaround with your quote.
Can you assess a renovation in an established Sydney suburb?
Yes -- knockdown-rebuilds and major renovations are some of the most common projects we assess across Sydney's established suburbs. Send us your plans and we'll confirm what's required.
