STCs and REPS are different
An installation may be eligible for STCs even when a REPS offer is unavailable.

STCs and REPS,
made clearer.
They are two separate programs. Our estimator can calculate an eligible STC allowance, while REPS depends on provider availability and customer eligibility.
SMALL-SCALE TECHNOLOGY CERTIFICATES
How the STC allowance works.
Eligible heat-pump water heaters can create Small-scale Technology Certificates under the Australian Government scheme. The number varies by the registered model, installation postcode and installation year.
- 01
Choose an eligible system
The exact model must be listed on the Clean Energy Regulator’s register and installed in accordance with its eligibility requirements.
- 02
We calculate the allowance
The online estimator uses the selected model, postcode zone and the 2026 deeming period to estimate the certificate quantity and discount.
- 03
Eligibility is confirmed
The final amount is confirmed before a formal quote. Supply-only estimates do not include an STC discount.
2026 ESTIMATOR ALLOWANCES
STCs by model.
These totals use the current estimator value and the 2026 certificate deeming period. Your installation postcode determines whether Zone 3 or Zone 4 applies.

Figures are indicative upfront credits for eligible installed systems. The exact model, postcode, installation date and assignment eligibility are confirmed before the formal quote. Supply-only sales do not receive an STC credit through our estimator.
SOUTH AUSTRALIAN REPS
A separate incentive,
subject to availability.
The Retailer Energy Productivity Scheme supports eligible energy-efficiency activities in South Australia. It is not a cash rebate paid directly by the government. Any incentive is normally applied through a participating retailer or activity provider.
Availability, customer eligibility, co-contributions and the activities offered can vary. Adelaide Heat Pumps’ current allocation status is shown at the top of this page and in the estimator.
Read the ESCOSA consumer information ↗GOOD TO KNOW
Before relying on an incentive.
The estimate is provisional
The online figure is useful for comparing options, but final eligibility and certificate quantities are checked before quoting.
Product details matter
Tank, heat-pump model, installation date and location all affect the certificate calculation.
