Battery STC assignment form: what to fill in

Short answer

A battery STC assignment form records the system owner handing the battery STCs to the installer. It needs the owner details, address, battery serial numbers, the recipient, the date and a signature, and each detail has to match the rest of the claim.

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

The form is the paper trail that lets the installer, and the trader behind them, own the certificates. It looks simple, and it causes a surprising number of delays.

Fields that must be right

Field What to check
Owner name Matches the electricity bill and compliance certificate
Property address Matches the registry and the grid connection
Battery make, model, serials Matches the CEC product and the photos
Installer or agent The legal name that will lodge the claim
Date On or after install and before lodgement
Signature The owner, legible, not a typed name without audit trail

Common mistakes

Serial numbers are the main one. They come from the battery label, and a single transposed digit can hold up the claim. Photograph the label and read the number off the photo, not off the box. The second most common error is a form signed by the wrong person, such as a tenant, a family member or an agent without written authority.

Where to get the form

Many traders supply their own template. Whichever you use, it should carry the declarations the regulator expects. Our assignment form guide explains each field, and the battery submission guide shows how it fits with photos and compliance paperwork.

A job-closeout routine that works

Scan the serial at install, send the form for e-signature the same day, and have a second person tick the serial against the photo before lodging. It takes two minutes and removes most of the typing and signature problems that stall claims. Keep the signed copy with the job file for the period the regulator requires.

From the desk: Send the signed form to your trader the same day. If there is a mistake, you can fix it while the customer is still happy and the install is fresh.

What this means for installers

A clean form is the cheapest way to avoid a re-lodgement. Add a checklist item to the job closeout, and make it part of the same screen as the serial number scan. For the broader picture see how assignment works and the battery STC pillar. Our desk pre-checks forms on every claim, and how it works shows where that fits.

Follow-up questions

People also ask

Do I need a separate form for solar and battery?
Treat each as its own claim. If you install solar and a battery together, keep the paperwork clearly separate and consistent.
Can the form be electronic?
Electronic signature is common, but keep a clear record showing who signed and when.
