This guide shows you how to check a licensed plumber in QLD, what insurance matters, how quotes should be structured, and the red flags that often lead to blowouts or compliance headaches.

Why licensing matters in QLD
Most plumbing and drainage work in Queensland is regulated and must be carried out by a QBCC-licensed plumber or drainer. Work falls into three buckets:
Permit work: Council permit before work starts (e.g., new builds or certain complex installs).
Notifiable work: No permit needed, but the plumber must register the job with QBCC after completion (Form 4/4A).
Minor work: Small repairs by a licensee, no permit or registration required.

Use the official QBCC licence search to verify a plumber or company:
Correct class (plumbing/drainage, backflow, gas, etc.)
Free from serious disciplinary history or suspensions
Insurance you should ask about
Before you sign anything, ask for certificates of currency and confirm:
Public Liability Insurance: Commonly $5m–$20m. Protects against injury/property damage claims during the job.
Contract Works (Construction Works): Covers the site and materials during the build/installation period.
Queensland Home Warranty Insurance (QHWS): Mandatory for residential building work over $3,300 (your contractor arranges and pays the premium via QBCC as part of your deposit).
For specialised work: Backflow testing, gasfitting, and certification tasks may have extra requirements.
Public liability isn’t always “legally mandated” for every small task, but it’s often required by contracts, licensing contexts, or site access—and it’s best practice protection for you and the plumber.
Notifiable work and Form 4/4A: what you’ll see on your invoice
A lot of everyday jobs in existing homes (hot water replacements, adding fixtures, backflow devices, etc.) are “notifiable work.” Your plumber must lodge a Form 4/4A with the QBCC and pay the fee—this is why you’ll often see a “Form 4” line item on your invoice.

What is notifiable work and how it’s registered: https://www.qbcc.qld.gov.au/worksite-building-practice/plumbing-work/what-notifiable-work
Notifiable work allows a licensed plumber to perform certain work without a local government permit, but they must register the work with the QBCC after completion (Form 4/4A).
Permit work: when Council approval is required
For new builds, major additions, or specific complex installations, permit work applies. On the Gold Coast:
Sewer-connected approvals can be issued in ~2 business days; unsewered can take up to ~10 business days (subject to complete documentation).
You or your plumber will coordinate inspections with Council.
- Proof of licence and current insurance (attach certificates)
Variations
- How unforeseen issues (e.g., hidden leaks, corroded pipes) are priced
- Any contingency allowances
Payment terms
- Deposit, progress payments, final payment on completion
- For jobs > $3,300, ensure QHWS is arranged by the contractor
Gold Coast pricing pointers
Typical call‑out fees and hourly rates vary by urgency and time of day. Expect higher rates for after‑hours emergencies and weekend work.
Hot water system replacements and backflow devices often appear as fixed-price line items plus compliance lodgement (Form 4).
For larger residential projects (> $3,300), Queensland Home Warranty Insurance applies; your builder/contractor collects the premium as part of the deposit and pays QBCC on your behalf.
Note: Prices fluctuate with supply costs and demand. Always get two to three itemised quotes.
Red flags to avoid
Can’t or won’t provide a QBCC licence number
Licence name doesn’t match trading name on the quote/invoice
No public liability or expired insurance certificates
Cash-only, full payment upfront, or unusual pressure tactics
Refuses to list WaterMark-certified products or exact model numbers
Avoids permits/Form 4 lodgements when required
Very low quote with lots of “TBA” items or unclear exclusions
Poor communication on warranties or variation process
Negative disciplinary history, suspensions, or excluded individuals (check QBCC registers)
Use the QBCC register to check if a plumber or company has suspensions, cancellations, or exclusions:
Step-by-step: book a licensed plumber the right way
Shortlist local Gold Coast plumbers
Look for proven experience with your specific job (e.g., HWS, backflow, bathroom renos).
Verify licence and history (QBCC)
Confirm active licence, correct class, and clean history via QBCC registers.
Request itemised quotes
Ask for model numbers, WaterMark compliance, labour/time, Form 4/permit handling, warranty terms.
Check insurance certificates
Public liability and, where relevant, contract works. Ensure currency covers your job dates.
Confirm compliance steps
Who lodges Form 4, arranges inspections, and provides final documentation.
Approve and schedule
Agree on scope, price, variations, and payment terms in writing. Keep copies.
Specialised licences and endorsements
Some tasks need additional endorsements or specific qualifications:
Backflow prevention testing
Gasfitting
Fire services work
Complex drainage design
If your job involves these, make sure the plumber’s licence shows the relevant class/endorsement.
When to involve Council vs. notifiable work
Permit/Compliance Assessable Work: New builds, certain additions, or complex systems. Your plumber submits Form 1, Council assesses and inspects. See City of Gold Coast guidance linked above.
Notifiable Work (Form 4/4A): Most renovations/like‑for‑like replacements in existing buildings. The plumber registers the work with QBCC post‑completion.
Minor Work: Small repairs by a licensee, no permit or registration required.
Some minor tasks are unregulated (e.g., changing a shower head), but most plumbing is regulated in QLD. When in doubt, check QBCC’s unregulated work guide and remember: anything beyond very basic tasks typically requires a licensed plumber.
For notifiable work, your plumber must lodge a Form 4/4A with QBCC. The fee and admin are commonly passed through as a line item. It’s proof the job was registered for compliance.
That’s a red flag. Ask for certificates of currency. If they refuse, choose another contractor.
Keep copies of: quotes, licence checks, insurance certificates, permits/Form 4 receipts, warranties, and final invoices. If issues arise later, this paperwork makes it much easier to resolve.
