BASIX assessments for homes, renovations, townhouses and apartments in Sydney and across NSW. We help you understand the specification choices, coordinate the assessment with your drawings and prepare the agreed compliance documentation.
Send your plans now, or start with a few project details.
SPECIALIST ADVICE FOR YOUR PROJECT
We review the project information and confirm the applicable assessment scope before work begins. Your proposal identifies the BASIX service, any NatHERS modelling required, the documentation to be prepared and the information needed from your design team.
Glazing, insulation, shading and construction choices affect one another. We discuss practical options with you so the assessment supports the design and the build. Share any preferred products or design constraints at the start rather than waiting until the certificate is ready.
The cost depends on the type of project, dwelling count, design complexity and whether thermal modelling is included. Ask for a written total that explains professional fees, GST and any certificate or government charges. We confirm these in your project proposal; a certificate fee alone is not the full assessment price.
Upload your current site plan, floor plans, elevations and sections if available. Include the project suburb, the number of dwellings and whether this is a new build or an alteration and addition. For revisions, send the existing certificate and explain what has changed.

No. BASIX is the NSW assessment and certification framework. NatHERS modelling assesses thermal performance and can form part of the BASIX assessment. We confirm which services your project needs.
Yes. Early advice gives your design team time to consider alternatives. Enquire with the drawings you have and tell us what is still being decided.
Send the current certificate, revised drawings and a description of the changes. We will check the existing assessment, access requirements and revision scope before quoting.
