Buying window film in Australia? Ask for these three records

What does WERS For Film mean?

WFAANZ describes an Australian program with three parts: film ratings, individual accreditation and energy certificates for completed work. It says the accredited person checks the project before and after installation, with the checklist attached to the certificate. Read the program explanation.

Think of your estimate as the start of a small project folder, not the whole story. Give each of the following records its own place.

1. The exact film

Ask the shop to write the manufacturer, product name and shade on the estimate. Save the rating record they supply beside it.

• Does the product name match in both places?
• Can the shop explain what window setup the rating describes?
• If they suggest a different film later, will they update the estimate and supporting record?

You do not need to guess what a similar-sounding product name means. Ask for the missing detail before comparing the offers.

2. The person responsible

AGWA/WERS says a film applicator needs a WERS licence to certify WERS energy ratings. Check the named person against WFAANZ’s current list; ask WFAANZ if their status is unclear. See the licensing guidance.

Write down who will answer your certificate questions. If a salesperson arranged the estimate, ask who will handle the checks and final paperwork. That avoids a last-minute “someone else deals with that.”

3. The paperwork for your job

Before accepting the estimate, ask what documents are included, when you should expect them and whom to contact if something is missing.

Keep those answers with the final invoice, warranty and care instructions. Ask about any mismatch while the details are fresh.

A quick example

Imagine two estimates for your living-room windows. One names the film but says only “certificate included.” The other names the film, the person handling the certificate and the promised handover documents.

The second is easier to check. That does not automatically make it the better film or the better price. It means you can see what is being offered and ask the first shop to fill the gaps.

Keep the next decision separate

A certificate is not a substitute for asking whether the film suits your existing glass. Keep that question, any predicted bill savings and any building-approval requirements separate. Ask the relevant supplier or assessor what evidence they need for your actual project.
