STC compliance, audits, clawbacks and fraud

How do you report STC fraud or a dodgy solar installer to CER?

Short answer

Report suspected STC fraud to the Clean Energy Regulator through its online reporting tool, which allows anonymous reports, or by email to referrals@cer.gov.au or phone on 1300 553 542. Include names, dates, addresses and what you saw, and report safety issues to your state electrical regulator.

Written and checked by the Energy Merchants desk · Reviewed 3 October 2026 · For installers and homeowners

If you think an installer or agent is creating STCs for jobs that were not done, falsifying photos or taking customers’ money without delivering, the Clean Energy Regulator wants to hear about it. It is a regulator, so it will not tell you what it does with a tip, but reports feed into audits and investigations.

Ways to report to CER

  • The online reporting tool. CER’s reporting page lets you lodge a report about suspected fraud or corruption. It has adopted a platform that allows anonymous reporting and keeps a conversation open between you and the regulator without revealing who you are.
  • Email. referrals@cer.gov.au
  • Phone. 1300 553 542 within Australia, or +61 2 6159 3100 from overseas.
  • Post. Complaints, Clean Energy Regulator, GPO Box 621, Canberra ACT 2601.

Check the CER website for current details before you contact them, because channels change.

What to include

A good report is specific. Include:

  1. the name of the person or company, and their role
  2. the dates and addresses involved
  3. what you saw or know, and how you came to know it
  4. any evidence: photos, invoices, messages, claim references
  5. anyone else who knows

Do not confront the person first, and do not alter or delete evidence. Keep it as it is.

Who else to contact

Reporting a competitor or a subcontractor

Installers and traders sometimes see odd claims from rivals, subcontractors or past employers. Report facts, not rumours. A claim made out of spite without evidence helps nobody. If it is your own subcontractor, you should also address it internally, since your accreditation may be on the work; see phantom installations.

What this means for installers

Making a report does not expose you to risk where it is made in good faith, and it supports an industry where honest installers are not undercut by people claiming for work they never did. If you have made a mistake of your own, a prompt correction through your trader is better than waiting; see what to expect from an audit.

From the desk: write down what you know the same day, with dates. Memory fades and the regulator will want specifics.
