A burst pipe or a blocked drain at the worst possible moment is exactly when people get taken advantage of. You’re stressed, water is rising, and someone is standing in your hallway quoting a number. Most Melbourne plumbers are honest — but a small number rely on that pressure, and knowing the warning signs is the best protection you have. Around The Clock Plumbing Pty Ltd, Oakleigh South has spent more than two decades doing this work the straight way, and this guide lays out how the scams work, how to check a plumber is properly licensed, and what a fair-dealing plumber does differently.

How Plumbing Scams Usually Work

Most dodgy jobs follow a familiar script. It often starts with an unsolicited approach — a cold call, a letterbox flyer, or a door-knock ‘noticing a problem’ with your pipes. From there the tactics are predictable: manufactured urgency (‘this has to be fixed today or it’ll flood’), a quote given verbally and never in writing, and a demand for a large cash deposit before any work is done. A common version is the job that balloons — a cheap-sounding call-out turns into a long list of ‘extra’ problems once the plumber is under the house, with the price climbing well past anything you agreed to. The pressure is the point: you’re meant to feel you’ve no time to check anything or get a second opinion.

How to Check a Plumber Is Licensed in Victoria

In Victoria, plumbing work is regulated by the Building and Plumbing Commission (BPC), which became the state’s building and plumbing regulator on 1 July 2025, taking over the role previously held by the Victorian Building Authority (VBA). You can check whether a plumber is properly registered or licensed using the free ‘Find a Practitioner’ directory, currently on the VBA website at vba.vic.gov.au. A few things worth knowing: licensing applies to individual plumbers, not companies, so check the name of the person who’ll actually do the work — not just the business. Every registered or licensed plumber carries a BPC plumbing practitioner ID card, and it’s reasonable to ask to see it; the back of the card lists the classes of work they’re allowed to carry out. Specialised work such as gas fitting, backflow prevention and thermostatic mixing valves each require their own class, so a plumber doing gas work should be licensed for it.

Warning Signs Worth Walking Away From

They approached you out of the blue — a door-knock, cold call or flyer.
You're being pushed to decide on the spot.
They want a large deposit before they've properly looked at the job.
There's no written, fixed-price quote.
They won't show a licence or BPC practitioner ID card.
The only contact is a call-centre number, and no one can tell you who's actually coming.
The price jumps mid-job without a clear, written explanation.

What a Straight-Dealing Plumber Does Differently

A fair-dealing plumber is easy to recognise once you know what good looks like. It starts before anyone arrives: a real, local person answers the phone — including after hours — and gives you an honest arrival window rather than a vague promise. They turn up when they say they will. On site, they diagnose the problem properly with the right equipment — acoustic leak detection with a Sewerin A200 to pinpoint a hidden leak, or a Ridgid CCTV camera down a drain to see exactly what’s blocking it — rather than guessing and upselling. They explain what’s actually wrong in plain terms, then give you a written fixed-price quote before any work starts, so the figure you agree to is the figure you pay. When the job’s done you get an itemised invoice, and the work is backed by a guarantee. None of that relies on pressure — it relies on doing the job correctly and standing behind it.

Around The Clock Plumbing is registered and licensed with the Building and Plumbing Commission under licence #50694, and holds Type A gas, backflow and thermostatic mixing valve qualifications. The business carries $20 million in public liability cover, backs its work with a six-year workmanship guarantee, and has operated across Melbourne’s south-east since 2012 (ABN 49 159 059 702). Founder Christopher Unwin has 22 years in the trade and sits on the National Council of the Master Plumbers Association. Every job is quoted as a written fixed price before work starts, and we never ask for a large upfront deposit — the same standards this guide suggests you hold any plumber to.

Common Questions About Plumbing Scams and Licensing

How do I check if a plumber is licensed in Victoria?

Use the free ‘Find a Practitioner’ directory, currently hosted on the Victorian Building Authority website at vba.vic.gov.au. Plumbers are regulated by the Building and Plumbing Commission (BPC), and every registered or licensed plumber carries a BPC practitioner ID card you can ask to see. Because licensing applies to individuals rather than companies, check the name of the person doing the work.

Who regulates plumbers in Victoria?

Victoria’s plumbing regulator is the Building and Plumbing Commission (BPC), which took over from the Victorian Building Authority on 1 July 2025. The public register used to verify a plumber is still accessed through the VBA website during the transition.

What are the warning signs of a plumbing scam?

Common red flags are an unsolicited approach (a door-knock, cold call or flyer), pressure to decide immediately, a demand for a large deposit before the job is properly assessed, no written fixed-price quote, refusal to show a licence or ID card, and a price that suddenly balloons mid-job without explanation.

Should I pay a plumber a large deposit upfront?

Be cautious. A reputable plumber gives you a written fixed-price quote before starting and does not demand a large deposit before seeing the job. Around The Clock Plumbing provides a written fixed-price quote upfront and never asks for a large upfront deposit.

What should I do if a plumbing job suddenly costs much more than quoted?

Stop and ask for the change to be put in writing, with a clear explanation of why the price has changed. You are entitled to that, and it is reasonable to get a second opinion before agreeing to extra work — especially if you feel pressured to decide on the spot.
