If your crew finishes a dozen jobs a week, submitting one at a time is a drag. Bulk upload helps, but only if you understand what it changes and what it does not.
What batch or bulk submission means
In practice, three things sit under that label:
- Spreadsheet upload. A file with one row per system: customer, address, system size, serials, installation date, accreditation numbers.
- Evidence attached per job. Photos and signed assignment forms, in folders or tagged by job number.
- A batch lodgement. The trader checks each row, then lodges the claims in the REC Registry together or in sequence.
Some platforms integrate with job management or quoting software, so data flows through without retyping. See STC form apps for installers.
What bulk does not change
Every system is an individual claim. The CER validates and can audit each one. A mistake in row 7 does not sink rows 1 to 6, but a systematic mistake does: a wrong zone, a repeated serial format error or a missing photo type across the whole batch can fail many claims at once. See why claims are rejected.
Getting a clean batch
- Use a template and keep columns consistent (serials, dates and postcodes in the same format).
- Check the installation date against the commissioning date and the deeming period for that year.
- Confirm product approvals and accreditation for every row.
- For batteries, include the evidence under the photo rules in force since 1 March 2026. See the battery submission guide.
- Upload photos at job close, not at month end.
Cut-offs and batch size
A batch usually counts for the day it is complete. If row 14 is missing a photo, ask whether the other 13 proceed or the batch waits. See cut-off times. Smaller, frequent batches also limit your exposure to a falling market between job and lock.
Handling failures
If a claim fails, fix the cause and resubmit. See fixing a failed STC claim. Ask in advance whether resubmission is free.
What this means for installers
Choose a trader whose bulk tools reduce your admin without hiding errors. Our compliance desk reviews photos, forms and serials before anything is lodged and a named account manager looks after your account. See how it works, start trading and the STC trading pillar. Rates are on pricing.
Batteries and hot water in the same batch
Mixed batches need care: each product type has different evidence, so separate rows or files by type. Batteries need serials and VPP evidence, and hot water needs plumber and installation details. Mixing them without labels is a common cause of delays.
