A freshly renovated bathroom or kitchen is a strong selling point — but a good-looking reno doesn’t tell you whether the plumbing work behind the walls was done properly, or even legally. In Queensland, this is where the QBCC’s notifiable work system comes in.
What counts as notifiable work
Most plumbing and drainage work in Queensland is regulated, and it must be carried out by a licensed plumber or drainer. Some categories of work — like bathroom renovations or installing a new hot water system — fall under what’s known as “notifiable work.” For this category, the plumber is required to lodge a Form 4 (or Form 4a) with the QBCC once the job is finished, and provide a copy to the homeowner.
This is different from “permit work,” which requires council approval before work even starts, and different again from minor work, which doesn’t need registration at all. Notifiable work sits in the middle: no permit needed beforehand, but formal registration required afterward.
Why this matters when you’re buying
If a property you’re considering has had recent renovations — a new ensuite, a relocated kitchen, an upgraded hot water system — we’d always suggest asking whether that work was ever registered as notifiable work with the QBCC. A registered Form 4 is some assurance that a licensed plumber did the work, and it’s been recorded on the public record. No Form 4 on file doesn’t automatically mean the work is defective, but it does mean there’s no official confirmation the job was done by a licensed tradesperson, to code.
The QBCC does run audits of notifiable work to check it’s been registered and meets technical requirements, and local governments can also inspect plumbing work to confirm it meets the relevant codes and standards. But that’s a compliance mechanism for after the fact — it’s not a guarantee for a buyer walking through an open home today.
How to check
The QBCC maintains an online register where notifiable work (Form 4/4a) can be searched. We’d recommend this as a useful first step for any buyer eyeing a recently renovated property, particularly if the seller or agent can’t produce documentation on request.
What to do if there’s no record
If you can’t find a registered Form 4 for renovation work that clearly involved plumbing, that’s not necessarily a dealbreaker — but it is a reason to get an independent set of eyes on the work before you commit. We can assess whether the work looks compliant, correctly installed, and fit for purpose, regardless of whether the paperwork exists.
A finish and a fact are two different things
A renovated bathroom tells you what it looks like. A registered Form 4 tells you who did the work. Neither one, on its own, tells you whether it was done properly.
