Unlicensed vs. Licensed Plumbing: Why It Matters Who Installs Your Bathroom Plumbing

When you're planning a bathroom renovation or dealing with a plumbing emergency in Melbourne, you'll face a critical choice: hiring a licensed plumber or taking a chance with an unlicensed contractor.

While the price difference might seem tempting, the decision you make could affect your home's safety, your insurance coverage, and your wallet for years to come. At Apex Trades Services, we've seen firsthand the costly mistakes that result from unlicensed work. This guide breaks down why that license is your biggest safeguard.

What Is a Licensed Plumber?

A licensed plumber in Victoria isn't just someone who knows their way around a pipe. They have completed a rigorous apprenticeship, passed competency assessments, and hold current registration with the Victorian Building Authority (VBA).

Licensed plumbers must:

• Complete a minimum four-year apprenticeship.

• Hold current plumbing registration with the VBA.

• Carry adequate insurance coverage.

• Stay updated on Victorian plumbing regulations and Australian Standards.

Key Differences Between Licensed and Unlicensed Plumbers

1. Legal Compliance and Qualifications

In Victoria, it is illegal for anyone to perform plumbing work without proper licensing.

The Cost of Breaking the Law: If you are caught using an unlicensed plumber, you could face fines up to $99,132 for individuals or $495,660 for corporations.

2. Insurance and Liability Protection

Most homeowners don’t realize that insurance policies specifically exclude damage caused by unlicensed tradespeople. If an unlicensed worker causes a flood, you are likely paying for the repairs entirely out of pocket.

3. Quality and Building Codes

Licensed contractors understand the Victorian plumbing regulations inside and out. This is crucial for bathroom installations where incorrect pipe sizing or faulty waterproofing can lead to structural rot and mold.

4. Permits and Documentation

A licensed professional provides a Compliance Certificate. You’ll need this when you sell your home; without it, buyers can demand you redo the work at your own expense before the sale proceeds.

Why Licensing Matters for Bathroom Installations

Bathroom renovations involve complex systems. A single mistake in drainage or waterproofing can lead to:

• Water damage to walls and floors (Average repair: $5,000–$15,000).

• Mold growth from poor waterproofing (Remediation: $3,000–$10,000).

• Failed building inspections when selling your property.

The Verdict: Licensed vs. Unlicensed

5 Questions to Ask Before Hiring a Plumber

1. "Can I see your VBA license number?" (Verify this at vba.vic.gov.au)

2. "Do you carry public liability and professional indemnity insurance?"

3. "Will you obtain the necessary permits and provide a Compliance Certificate?"

4. "Can you provide references from recent bathroom renovations in Melbourne?"

5. "What warranties do you offer on your work?"

How to Verify a Plumber's License in Victoria

Protecting yourself is simple and takes less than two minutes:

1. Ask for their VBA registration number.

2. Visit the VBA website.

3. Use the 'Find a Practitioner' search tool.

4. Verify their registration is current and covers the specific type of work you need.

The Bottom Line: Professional Plumbing is Worth the Investment

The small amount you might save upfront by using an unlicensed contractor is dwarfed by the potential costs of legal fines, insurance complications, and repairs.
