How to claim in the Northern Territory

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.

The deeming period drops from 5 years to 4, so the same heat pump earns about one fifth fewer certificates than a 2026 install and the upfront discount falls with it.

Northern Territory heat pump rebate questions

Is there an NT heat pump hot water rebate in 2026?

No territory incentive was listed when we checked. The Home and Business Battery Scheme funds batteries, or solar with a battery, only.

How much is the federal STC discount in the Northern Territory?

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.
