Tradie Forms: avoid the Form 43 mistakes that send Queensland aspect certificates back for rework. Finish the certificate on the official PDF layout with guided sections, saved QBCC licence details, missing-field checks, preview, and a clean export.
QLD Form 43 is short enough to look easy and specific enough to punish sloppy wording. That is the dangerous combination. A QBCC licensee can finish the actual aspect work properly, then lose time because the certificate does not say what the certifier needs it to say.
The common issues are rarely dramatic. The scope is too broad. The aspect description does not say where the work was done. The building development approval number is copied from another job. The basis says "as per plans" but no plans are named. The licence class is missing or stale. The PDF is signed, sent, and then the phone rings.
Use this guide alongside the QLD Form 43 template when you want to finish the official PDF layout cleanly. You can also browse QLD building forms, read the broader QLD Form 43 guide, or check QLD Form 30 if the work is accepted development rather than work under a building development approval.
Mistake 1: using Form 43 for the wrong job moment
The official Form 43 PDF says it is used to state that aspect work for a single detached class 1a building and class 10 building or structure is compliant with the building development approval. The appendix says it is used when the QBCC licensee carried out, or is authorised to certify, aspect work subject to a building development approval.
That means the first mistake is using Form 43 when the job is not a Form 43 job.
If the work is accepted development, Form 30 may be the correct QBCC licensee aspect certificate. If the certificate is about a stage inspection by a building certifier or appointed competent person, Form 16 may be the relevant stage record. If an appointed competent person is certifying an aspect inspection, Form 12 may be involved.
Do the form choice check before you start typing. It takes less time than fixing a completed PDF that was wrong from the first field.
Mistake 2: scope and aspect are treated as one field
Form 43 asks for both the scope of the aspect work and the description of the aspect or aspects certified. They are not duplicate boxes.
The scope should connect to the licence class. The aspect description should explain the actual work certified on this job.
Weak wording:
- "Waterproofing"
- "Structural steel"
- "Glazing"
- "Building work"
Better wording:
- "Wet area waterproofing to main bathroom, ensuite, and laundry"
- "Structural steel beams to rear patio roof, drawing S03 Rev B"
- "Glazing installation to ground floor external doors and windows"
The certificate should tell the certifier what is covered without a follow-up call.
Mistake 3: certificate wording covers work you did not certify
Broad wording can make the certificate look like it covers more than intended. This is a problem even when the work itself is fine.
For example, "all waterproofing works" might be too broad if you only certified the ensuite and laundry. "Structural steel" might be too broad if you only certified a defined beam or frame section. "Glazing throughout" might be wrong if only one facade was covered.
Tie the wording to the actual area, component, system, or stage. If the builder or certifier needs more than one certificate, it is better to issue clear certificates than one vague certificate that invites arguments later.
Mistake 4: the basis says nothing useful
The Form 43 PDF asks for the basis for giving the certificate and the extent to which tests, specifications, rules, standards, codes of practice, and other publications were relied on by the QBCC licensee.
"As per plans" is usually too thin. "Installed to code" is not much better.
Good basis wording points to the material you actually relied on:
- Relevant drawing numbers and revisions
- Product installation guides
- Engineering specifications
- Site inspection records
- Test records
- Applicable standards or codes where they are genuinely part of your assessment
Do not pad the field with references you did not use. A certificate should be clear, not inflated.
Mistake 5: reference documents are not identifiable
The reference documentation section is where you name the documents that support the certificate. A future reader should be able to find them.
Useful references include:
- Drawing S01 to S04, Rev C, dated 4 June 2026
- Manufacturer installation guide, product name, version or date
- Engineering letter or report number
- Test report reference
- Marked-up plan or photo set reference
If you attach documents outside Tradie Forms, keep them with the exported PDF in the job record. The certificate and the supporting documents should not drift apart.
Mistake 6: property details come from the invoice
An invoice address is not always the same as the land details needed for a building certificate. The official form asks for street address, state, postcode, lot and plan, and local government area.
Check the approval documents, title details, rates notice, or certifier request. This is especially important for:
- New estates
- Rural properties
- Duplexes and subdivisions
- Multiple jobs for the same builder
- Properties with unit or lot details
Wrong property details make the certificate harder to match to the approval.
Mistake 7: certifier numbers are copied without checking
Form 43 asks for the building certifier reference number and building development approval number. These are small fields, but they connect the aspect certificate to the certifier file.
If you use saved text snippets, old PDFs, or a job system with repeat clients, check the numbers before export. One wrong digit can turn a clean certificate into office rework.
Mistake 8: the inspection request trail is unclear
Form 43 includes the date approval to inspect was received from the building certifier. This field helps connect the aspect certificate to the request that led to the inspection or certification work.
If the date is missing, the certifier may still understand the job, but the record is weaker. Check the email, work order, or certifier portal before exporting the PDF. Keep that request with the job file if it explains the scope or timing.
Mistake 9: licence details are stale
The official Form 43 appendix says the QBCC licensee must hold an appropriate class of licence under the QBCC Regulation for the aspect work, or be authorised to give a QBCC licensee certificate for aspect work.
That makes the licence block more than a contact detail. Check:
- Full name
- Company name
- Licence class
- Licence number
- Postal address
- Email and phone
Tradie Forms can save licence details for repeat work, but you still need to check the details before signing, especially after renewals, business changes, or staff changes.
Mistake 10: signature happens before review
The signature should be the last thing, not the first. Review the whole PDF preview before signing or sending.
Check:
- Does the aspect match the actual work?
- Does the basis name real supporting material?
- Are references identifiable?
- Are approval and certifier numbers correct?
- Are licence details current?
- Is the date right?
Tradie Forms lets you preview the official PDF layout before download. Use that preview as the final check, not just a nice-to-have.
Mistake 11: the certificate is not stored with the job record
Form 43 usually sits inside a wider handover pack. If you send the PDF and do not store it, the office may struggle later when the owner, builder, certifier, or regulator asks for the record.
Keep the exported Form 43 with:
- Building development approval details
- Certifier request or approval to inspect
- Drawings, product documents, and reports
- Photos or inspection notes
- Related Form 16, Form 12, or Form 30 records where relevant
- Email or job-system handover record
Use a file name that tells the story. Date, property, aspect, and Form 43 is enough for most teams.
A simple pre-send checklist
Before sending, read the PDF in preview and answer five questions. Is this definitely Form 43, not Form 30? Does the aspect wording match the actual work? Are approval and certifier numbers correct? Are the licence details current? Can the references be found by someone else in the business?
If any answer is shaky, fix it before the certificate leaves site. Rework is slower after the builder, certifier, and office have all seen the wrong PDF.
How Tradie Forms helps
Tradie Forms reduces the boring mistakes by turning the flat PDF into guided sections:
- Scope
- Property
- Building
- Aspect
- Basis
- References
- Certifier
- Licensee
- Signature
It can reuse saved QBCC licence details, flag missing fields before export, show the official PDF preview, and let you download the completed certificate for handover.
That does not replace the QBCC licensee's judgement. It just makes the paperwork less fiddly when the details are fresh.
