When a Victorian heat pump or similar product creates both federal STCs and Victorian VEECs, you are running two schemes in parallel. The overlap is legitimate where the product and activity qualify under both, as covered in stacking VEECs and STCs on the same job and heat pumps in particular. This page is about the paperwork.
Two claims, two sets of records
STCs are created through the Clean Energy Regulator’s registry. You need a signed STC assignment form from the owner, the installation evidence (see photo requirements), the product details and your accreditation or licence detail. The claim can be audited, as explained in how STC audits work.
VEECs are created by an accredited provider under Victorian Energy Upgrades, run by the Essential Services Commission. The provider needs the customer’s consent and prescribed records for the activity, such as the installation date and address, the product model, the replaced equipment where relevant, and a signed customer declaration. If you are not an accredited provider yourself, you usually assign your rights to one. See who the accredited providers are and VEEC aggregators.
Assignment forms are not interchangeable
An STC assignment form transfers the right to STCs to a registered agent. A VEEC assignment moves the right to create VEECs to an accredited person. They are separate documents under separate schemes. A form that mentions only one scheme does not transfer the other. If you use a combined document, make sure it names both schemes and carries the owner’s signature against each. For the STC side, see what the form must include and the heat pump form.
What about solar?
Rooftop solar PV generation is not a Victorian Energy Upgrades activity, so there is no VEEC to stack with the STCs on a standard solar job. The Victorian overlap on solar is the Solar Victoria rebate, a separate state program with its own eligibility, income cap of $150,000 from 1 July 2026 and installer requirements. For how that interacts with an STC claim, see Solar Victoria installer requirements. For other states, see state rebates and STCs on solar.
Keeping the file tidy
Keep one job folder with the signed forms for both schemes, product labels, before-and-after photos and the invoice that shows each benefit separately. That makes either regulator’s request easy to answer.
From the desk: The common slip is a customer who signs one form on the day and assumes both are covered. Ask them to sign each document separately and keep the dates aligned with the installation date.
What this means for installers
Build a checklist per scheme and tick both before you submit either claim. Settlement timing differs, as set out in how long VEEC payment takes and our STC payment timing insight. For the bigger picture see VEECs and STCs on the same job and the STC trading pillar, or the VEEC trading page. Energy Merchants’ compliance desk pre-checks STC claims; see how it works.
