STC process and payment timing

What is STC pre-approval?

Short answer

STC pre-approval is a review of a claim's photos, forms and data before it is lodged in the registry, so errors can be fixed first. The term is used in different ways, so check whether a trader means their own compliance check or a Regulator process.

Written and checked by the Energy Merchants desk · Reviewed 2 October 2026 · For installers

Pre-approval is a loose term. In most conversations with traders, it means a check before lodgement. It is a good habit, and it is worth knowing exactly what yours includes.

What a pre-check usually covers

  • Photos. Are they sharp, in the right order, and do they show the required elements?
  • Serial numbers. Do the panels and inverter serials match the product and the registry data?
  • Forms. Is the assignment form signed, dated and consistent with the system?
  • Eligibility. Is the product on the approved list, is the installer’s accreditation current?
  • Classification and zone. New, replacement or addition, and correct postcode zone.

If anything is wrong, the claim is sent back for correction rather than lodged and bounced.

Why it matters

A rejected claim wastes days. A pre-check turns that into a same-day correction. It also builds an evidence file that helps if an audit follows. Our list of top rejection reasons shows what is typically caught.

Outcome Corrected claim Possible invalidation
From the desk: Ask any trader what their pre-check includes, and who looks at the photos, a person or software. Both are useful, but a person catches the odd cases.

Building it into your routine

The easiest way is to nominate one person to run the pre-check on every job on the same day, using a fixed template. The check takes five minutes if the photos are well organised. Log the result, and share common failures with the crew each month. After a quarter you will see which errors repeat and can fix them at the source, for example by changing a photo app or retraining a crew lead.

What this means for installers

A pre-check pays for itself the first time it catches a mismatch. Our compliance desk reviews each claim before lodgement, at no charge, as part of how it works. For the wider picture see fast-track STC payment, how audits work and the STC trading page.

Follow-up questions

People also ask

Does pre-approval guarantee payment?
No. It reduces the chance of rejection, but later audits can still find issues.
Does it cost extra?
It depends on the trader. Ask whether a pre-check is included in the rate.
