How much does a heat pump hot water system cost in Perth?
Most Australian installs run $2,500–$5,500 supplied and installed before incentives. Federal STCs come off at the point of sale everywhere, and state schemes can cut the price much further — in some states well-priced systems land near or under $1,000 after everything. Compare at least three quotes; spreads on identical units are common.
What hot water rebates apply in Western Australia?
Federal small-scale technology certificates (STCs) apply Australia-wide. On top of that, Western Australia support differs by scheme — check our rebate calculator for what applies to Perth households, and confirm final amounts with the installer, since accredited providers apply most incentives as upfront discounts on the quote.
How do I check a Perth installer is legitimate?
Hot water installs must be done by a licensed plumber (and electrician where required), and rebate-eligible installs generally require scheme-accredited providers. Ask for the licence number, confirm scheme accreditation for your state's rebate, and cross-check what the company claims on its own website — that's the source for the 4 listings on this page.
