Heat pump hot water rebate in WA, explained straight
Western Australia currently runs no state hot water scheme, but federal STCs still cut the upfront price of eligible heat pump systems at point of sale — and Perth's mild climate is close to ideal for heat pump efficiency, so running-cost savings do the heavy lifting.
What support exists in WA
- Federal STCs: applied at point of sale on eligible systems, commonly worth several hundred to over a thousand dollars depending on the system.
- No state scheme currently operates for hot water — if that changes, this page will be updated (we review scheme information weekly).
What Perth households actually pay
- Typical installs run $2,500–$5,500 before STCs. Against an electric storage system, a heat pump uses roughly 70–75% less energy for the same hot water — in Perth's climate the payback maths is among the best in the country even without a state rebate.
- If you have rooftop solar, running the heat pump on a daytime timer effectively heats water with your own generation — the strongest economics available.
Quick answers
Is there any WA government rebate for heat pump hot water?
Not currently at state level — federal STCs are the incentive that applies, taken off the price at point of sale. We review scheme information weekly and will update this page if WA introduces one.
Are heat pumps worth it in WA without a state rebate?
Often yes: Perth's mild climate suits heat pump efficiency, STCs still reduce the upfront cost, and the 70–75% energy saving versus electric storage carries the economics — especially paired with rooftop solar.
How much are STCs worth on a hot water system?
It depends on the system and zone — commonly several hundred to over a thousand dollars, applied as a point-of-sale discount by the installer.
