How long does it take to claim and register STCs?

Short answer

Lodging a claim takes minutes if your photos, statement and assignment form are ready. The CER then validates the claim and registers the certificates, typically within days, longer if it is flagged for review.

Claiming is the easy part. The time is spent getting a claim into a state where it will not be sent back.

The claim, step by step

An STC claim is a package: the installation details, geotagged photos, the installer’s written statement, the customer’s signed assignment form, and the equipment serial numbers or product codes. Lodged in the REC Registry by you or by a registered agent on your behalf, it is a data entry job of minutes once everything is to hand.

When STCs get registered

Registration happens after the Clean Energy Regulator (CER) validates the claim. A clean claim usually registers within days. A claim that trips a check, such as a mismatch between the serial and the approved equipment list, an installation date problem or a flagged installer, can sit longer while the CER reviews it.

Once registered, the STCs sit in the account of whoever holds the right to create them, and they can be transferred. That transfer is what the buyer pays for. For the money side see how long it takes to get paid for STCs.

How to keep the timeline short

  • Lodge as soon as the job is complete, ideally the same week. There is a 12-month window from install, and an old claim has more chance of a missing photo or an unreachable customer.
  • Check photos before lodging against the photo requirements.
  • Make sure the installation type is right: new, replacement or additional. See installation type.
  • Have a second set of eyes on serial numbers. The most common bounce reason is a typo.

What this means for installers

If you lodge yourself, you own the validation risk and the wait. If you lodge through a registered agent or trader with a compliance check, the claim gets reviewed before it reaches the CER, which tends to cut the back and forth. Our compliance desk pre-checks every claim at Energy Merchants, so problems are caught before they cost days. Read how STC audits work to see why a flagged claim takes longer, and the top rejection reasons to avoid them.

From the desk: the fastest claims are boring ones. Same-week lodgement, full photo set, serial numbers read off the labels, and a signed form on file.

Follow-up questions

People also ask

When do STCs get registered?
After the claim is lodged in the REC Registry and the CER validates it. Registration is the point where the certificates exist and can be transferred to a buyer.
Is there a deadline to claim STCs?
Yes. Certificates must be created within 12 months of the system being installed, so do not leave old jobs sitting. Check the CER's current guidance for the exact rule that applies to your system.
Does the customer have to do anything?
They sign the assignment form (or you hold their written assignment), which transfers their right to the STCs to you or your agent.
