Your BASIX Compliance Made Simple

Planning a renovation, extension or upgrade to your existing home? If your project in New South Wales exceeds $50,000 in value, you’ll need a BASIX Certificate to meet state sustainability requirements. At BASIX Certificates, we simplify the process—delivering fast, accurate certificates so you can focus on building, not the paperwork.

Whether it’s adding a bedroom, updating your kitchen, or expanding your living space, our team provides expert support to ensure your alteration or addition meets BASIX water, energy and thermal performance targets.

Why You Need a BASIX Certificate for Alterations & Additions:
The NSW Government requires a BASIX Certificate for all alterations and additions valued at $50,000 or more. These projects must comply with the same sustainability standards as new builds—helping reduce long-term energy and water use while improving comfort.
