BASIX Certificates – Compliance Made Simple
In New South Wales, a BASIX Certificate (Building Sustainability Index) is a mandatory requirement for most residential development projects. It demonstrates that your building design meets government sustainability standards for energy, water, and thermal comfort.
At Aussure, we provide fast, accurate BASIX Certificates for new dwellings, renovations, secondary dwellings, and additions — ensuring compliance and a smooth pathway to your Complying Development Certificate (CDC) or Development Application (DA).
When You Need a BASIX Certificate
A BASIX Certificate is required for:
New homes
Alterations or additions to existing dwellings
Secondary dwellings (granny flats)
Subdivisions with new dwellings
Residential renovations affecting energy or water efficiency
Any project requiring council DA or CDC approval
We check your project against BASIX water and energy targets and prepare a certificate ready for lodgement.
What We Do for Your BASIX Certificate
Our service ensures compliance and simplifies the process:
✔ Complete BASIX Assessment
We calculate energy, water, and thermal comfort performance using the official NSW BASIX tool.

✔ Integration with CDC/DA Applications
We issue the BASIX Certificate in the correct format for council or NSW Planning Portal submission.
