STC payment not received or paid late: what to do and how to chase

Short answer

Check the claim status in the REC Registry and your terms first, then contact your account manager in writing with the claim IDs and dates. Most late payments are a held claim or a detail mismatch. If it drags past your agreed terms, escalate in writing and keep records.

Three searches, one situation: a payment that has not arrived, a trader that is paying late and how to chase. The approach is the same.

Step 1. Find out where the claim is

Before you ring anyone, check:

  • The REC Registry. Is the claim registered and have the certificates been transferred? If the CER has not validated it, payment may not be due yet.
  • Your terms. What starts the clock and when is payment due? See STC payment terms.
  • Your bank. Look for deposits under a different name or a lump sum.
  • Your inbox. Check spam for a remittance or a request for more information.

Often the “late” payment is a claim on hold for a missing document. See why payment has not arrived.

Step 2. Contact the desk in writing

Phone if it is urgent, but follow up with an email so there is a record. Include:

  • claim or job IDs and addresses
  • date lodged and date payment was due
  • the amount and rate expected
  • a request for a specific answer by a specific date

A good trader will tell you the same day what is holding the claim.

Step 3. Resolve the cause

The common causes are:

Cause Fix
Missing document or photo Supply it, then ask for a revised date
ABN or bank detail mismatch Correct through your account manager
CER validation delay Ask for the status and expected timing
Failed validation Fix the issue and resubmit. See fixing a failed claim
Trader processing error Request payment and an explanation

Step 4. Escalate if it drags on

If the agreed date has passed and you have no credible reason:

  1. Write to the trader’s management, quoting the agreement and the dates.
  2. Ask for payment by a set date.
  3. If nothing happens, see what to do when a trader disputes or withholds payment.

Do not transfer more certificates to a trader that owes you money.

From the desk: Stop lodging new claims with a trader that is behind on old ones. The exposure grows each week, and the trader has no incentive to catch up.

What this means for installers

Prevention beats chasing. Pick a trader that publishes its terms, sends remittance advice without being asked and has a named person you can call. At the first late payment, write it down, and at the second, change your behaviour. If you are weighing a switch, the switch page explains how moving across works, and how to check a trader is legitimate is a good place to start your due diligence.
