Heat Pump Hot Water Rebates in Western Australia (2026)

By PumpSwap. Checked against the official sources on 21 September 2026. How we check

Western Australia has no state heat pump hot water rebate in 2026. The incentive available is the federal STC discount, typically $500 to $800, taken off the installer's quote. Some local councils run their own programs, so it is worth checking with yours.

Total rebates and discounts: up to $800. PumpSwap's modelled installed price after rebates in Western Australia: $2,300 - $5,000.

How to claim in Western Australia

Choose a heat pump on the Clean Energy Regulator's register, because only registered models earn STCs. The installer or their agent takes the STC discount off the quote when you assign the certificates to them.
Certificates must be created within 12 months of the install, which your installer or their agent handles.
Ask for each discount to appear as its own line on the quote, so you can see nothing has been missed.

Western Australia heat pump rebate questions

Is there a WA heat pump hot water rebate in 2026?

No state rebate was listed when we checked Energy Policy WA and the energy.gov.au rebate finder. The WA Residential Battery Scheme covers batteries, not hot water.

How much is the federal STC discount in Western Australia?

It is typically $500 to $800 for a 2026 install. The exact figure depends on the model, your climate zone and the certificate price on the day, so ask for it as a separate line on your quote.

What changes on 1 January 2027?

The federal STC discount steps down every 1 January until the scheme ends in 2030. A heat pump installed in 2027 earns about one fifth fewer certificates than the same model installed in 2026, so the upfront discount falls with it.
