Professional BASIX Alterations and Additions in NSW

At the BASIX Certificate Centre, we can provide you with the BASIX Certificate for your Alterations & Additions from $135.00 (including GST), and for peace of mind to owners, designers and architects, our price will include consultation regarding the commitments our assessor has selected, with the possibility of alternatives if required.

NB: As of the 1st October 2023 the NSW Department of Planning will charge fees for generating a BASIX Certificate, and this will be added to our price, being $33.00 including GST.

Do you need a BASIX Certificate for your renovation?

Since 1 July 2007, any residential alteration or addition in NSW valued at $50,000 or more requires a BASIX Certificate as part of your Development Application.

This includes second storey additions, extensions, and larger renovation projects.

Our process

Send us your renovation plans and a description of the works.

We provide a free fee proposal, including consultation on the assessor's recommended commitments.

We provide you with a draft of the compliance items, and will discuss any questions or changes.

Once agreed, we issue your BASIX Certificate, ready to submit with your Development Application or CDC.

Most straightforward residential jobs are turned around within a few business days. For urgent projects, let us know when you get in touch and we'll do what we can to prioritise it.

Why Alterations & Additions are included in BASIX

On the 1st October 2006, all new Development Applications in New South Wales for Alterations & Additions with a value of $100,000 or more had required a BASIX Certificate.

Then on 1st July 2007, the New South Wales Government lowered the threshold to $50,000.

This ensures that practical measures (e.g. insulation, glazing, shading, hot water systems and any relevant water and lighting fixtures) are included when renovation work is planned. The aim is to further reduce greenhouse gas emissions and potable water consumption, as well as improve the thermal comfort of existing homes.

The BASIX requirements for Alterations & Additions set minimum efficiency standards for lighting and water fixtures and it may not be necessary to install a rainwater tank. However, if your work includes a Swimming Pool or outdoor spa, then a water tank will be required.
