Heat pump hot water rebates in NSW

NSW runs its hot water incentive through the Energy Security Safeguard, the umbrella for the state's certificate schemes. In practice you never deal with certificates: an installer working with an accredited provider takes the discount off your quote. The detail that trips people up is timing, because the paperwork has to be signed before the job starts.

What heat pump rebates are available in NSW?

Federal STCs come on top of these. See how STCs work.

Why is the discount bigger when replacing electric than gas?

The NSW figures are up to $640 replacing an electric water heater and up to $330 replacing gas. The scheme rewards energy saved, and swapping an electric element tank for a heat pump cuts electricity use the most. Around half of Australian households use electric storage hot water (energy.gov.au), so the electric to heat pump swap is the most common upgrade the scheme pays for.

That is the opposite of Victoria, where the push is to get households off gas. Victoria's VEU discount is also higher for electric to heat pump ($630) than gas to heat pump ($560). See Victorian rebates.

How do I claim the NSW hot water discount?

1. Find an installer working with an IPART Accredited Certificate Provider (ACP). IPART keeps a list (find an ACP). If you want to use your own licensed tradesperson, the government says they will need to partner with an ACP.
2. Get a written quote that shows the discount.
3. Sign and return the nomination form before installation begins. The NSW Government is blunt: "you won't be reimbursed for work already completed" (energy.nsw.gov.au).
4. Pay the minimum customer contribution and the balance of the quote.
5. Keep the Certificate of Compliance from the plumber (see below).

What does a heat pump cost in NSW?

The NSW Government's heat pump page gives an installed cost range of $2,000 to $6,000, depending on size, model and installer, and estimated savings of $200 to $800 a year on energy bills compared with a traditional system (energy.nsw.gov.au). Those are the government's ranges, not quotes. My cost guide sets them next to other published figures.

Which heat pumps are eligible in NSW?

The NSW Government says only the heat pumps on the Clean Energy Regulator register are eligible for incentives from the Australian and NSW governments. IPART also publishes a list of accepted water heater products (IPART product lists). The ESS needs a minimum 5-year warranty against defects. See how to check a model.

Is there a Peak Demand Reduction Scheme rebate for heat pumps?

No. The NSW eligibility pages for both electric to heat pump and gas to heat pump note that the activity is only eligible under the Energy Savings Scheme, not the Peak Demand Reduction Scheme (energy.nsw.gov.au). The PDRS currently covers batteries, virtual power plants, air conditioners, refrigerated cabinets and pool pumps (PDRS).

Who must install it in NSW?

The NSW Government says the installation "must be done by a licensed plumber and/or electrician" to be safe, compliant and eligible for incentives, and that you need a qualified gas technician if you are replacing a gas system. NSW Fair Trading treats replacing a hot water heater as minor plumbing work that still needs a Certificate of Compliance given to you (NSW Fair Trading).

This matters. Building Commission NSW inspected heat pump installations done under the ESS and found many "non-compliant to relevant Australian Standards and manufacturer's instructions", and that some contracting businesses didn't hold the right contractor's licence (Building Commission NSW). Use the installer checklist before you sign.

Can NSW renters get the discount?

The ESS incentive is for households installing or replacing a hot water system, so in a rental it is the landlord who would arrange it. The Home Energy Saver loans are open to landlords, and the upcoming Home Energy Saver discounts name renters as eligible applicants.

How do I cut running costs in NSW?

NSW is one of the three regions where the federal Solar Sharer Offer has run since 1 July 2026, with free electricity from 11am to 2pm each day for households who opt in (energy.gov.au). A heat pump with a timer on the general circuit can heat the tank in that window. A heat pump on a controlled load circuit won't benefit, because controlled load is charged separately. See solar and off-peak timing and the Sydney guide.
