NSW government rebates and savings
For NSW supply and installation orders, both federal STCs and state ESCs are assigned directly to us. Therefore, you receive the rebate benefit as a convenient point-of-sale discount.
For supply-only purchases, the customer must claim the STCs themselves after installation. Consequently, keep your installation paperwork and purchase details.
If you are buying in Western Sydney, rebates can help reduce the upfront cost. However, eligibility rules can change, so please check before ordering.
