BASIX certificates

Do I need a BASIX certificate?

You will need a BASIX certificate if you are lodging a development application in NSW for a new home or for any alteration and addition of $50,000 or more to an existing home.

How do I get a BASIX certificate?

A BASIX certificate is obtained after completing the sustainability assessment for your project using the online BASIX assessment tool. Usually a building professional does this. Once the design of your project has met the BASIX requirements and the fee paid, a certificate will be issued electronically as a pdf.

What information will be on my BASIX Certificate?

The certificate shows the commitments made in relation to energy, water and thermal comfort requirements and confirms that the proposed development will meet the Government sustainability requirements. Along with information which identifies and describes the proposal, the commitments on the BASIX Certificate will form part of the conditions of consent issued by the approval authority.
