Do You Need Qualifications To Be a Plumber? Here’s the Truth

Thinking about becoming a plumber but unsure if formal qualifications are required? You’re not alone. Many people assume plumbing is a “learn-on-the-job” trade with no paperwork—but the reality is more nuanced. The short answer to “Do you need qualifications to be a plumber?” is yes, in most U.S. states—and for good reason. Proper training and licensing protect both you and your clients. Let’s break down exactly what’s required, why it matters, and how to get started the right way.

What Qualifications Are Required to Become a Plumber in the U.S.?

In the United States, plumbing is a regulated trade. While requirements vary by state and even by city or county, nearly all jurisdictions require some form of licensure to work legally as a plumber—especially if you plan to run your own business or work independently.

According to the U.S. Bureau of Labor Statistics (BLS), “most states and localities require plumbers to be licensed.” This typically involves:

• Completing an apprenticeship (usually 4–5 years)
• Passing a licensing exam
• Meeting continuing education requirements (in some states)

Without proper credentials, you risk fines, legal trouble, or being barred from working on certain projects—especially those involving gas lines, sewage, or public infrastructure.

💡 Expert Insight: “Plumbing isn’t just about fixing leaks—it’s about public health and safety,” says Michael Johnson, Master Plumber and former president of the Plumbing-Heating-Cooling Contractors Association (PHCC). “Licensing ensures professionals understand code compliance, water efficiency, and system integrity.”

Do You Need a College Degree to Be a Plumber?

No. A traditional college degree is not required to become a plumber. In fact, most plumbers enter the field through vocational training or apprenticeships, which are more affordable, faster, and directly aligned with real-world skills.

Instead of a bachelor’s degree, you’ll typically need:

• A high school diploma or GED
• Completion of a plumbing apprenticeship (paid, on-the-job training)
• Trade school coursework (optional but helpful)

Apprenticeships are sponsored by unions (like UA Plumbers & Pipefitters), trade associations, or private contractors. They combine 2,000 hours of paid fieldwork per year with 144+ hours of classroom instruction—covering blueprint reading, local codes, safety, and tool use.

Plumbing License Types: Apprentice, Journeyman, and Master

Most states use a three-tier licensing system:

⚠️ Note: States like Kansas, Missouri, and Wyoming have no statewide plumbing license—but local municipalities often do. Always check with your city or county building department.

Can You Work as a Plumber Without a License?

Technically? Sometimes—but it’s risky.

You may be able to:

• Work as an apprentice under a licensed plumber
• Perform minor DIY repairs in your own home
• Handle non-regulated tasks (like installing a faucet in non-structural areas)

However, if you:

• Advertise plumbing services
• Pull permits
• Work on gas lines, drains, or water supply systems
  …you must be licensed in most areas.

Unlicensed work can lead to:

• Fines up to $5,000 (varies by state)
• Voided home insurance claims
• Liability for water damage or code violations

A 2023 study by Angi found that 68% of homeowners would refuse to hire an unlicensed plumber—even for small jobs—due to safety and legal concerns.

Pros and Cons of Getting Licensed vs. Staying Informal

The BLS reports the median annual wage for plumbers was $60,090 in 2024, with top 10% earning over $103,000. Licensed pros also enjoy job stability—plumbing is recession-resistant and in high demand due to aging infrastructure and housing shortages.

FAQ: Common Questions About Plumber Qualifications

Q1: How long does it take to become a licensed plumber?
A: Typically 4 to 5 years through an apprenticeship, plus exam prep. Some accelerated programs take 2–3 years but still require supervised hours.

Q2: Can I get a plumbing license with a criminal record?
A: It depends. Minor offenses may not disqualify you, but felonies related to fraud, violence, or drug use could. Check your state’s licensing board for policies.

Q3: Do plumbers need certifications beyond a license?
A: Not always—but certifications (e.g., in backflow prevention, medical gas, or green plumbing) can increase earning potential and job opportunities.

Q4: Is plumbing school worth it?
A: Yes, if it’s part of a registered apprenticeship. Standalone trade school without hands-on training may not prepare you for licensing exams or real-world work.

Q5: Can I transfer my plumbing license to another state?
A: Some states have reciprocity agreements (e.g., within the Midwest or New England), but many require you to pass their specific exam or complete additional hours.

Q6: What’s the difference between a plumber and a handyman?
A: Handymen handle minor repairs (e.g., unclogging a sink), but only licensed plumbers can legally install or modify water/gas lines, sewer systems, or code-regulated fixtures.

Conclusion

So, do you need qualifications to be a plumber? Absolutely—if you want to build a safe, legal, and profitable career. Licensing isn’t about red tape; it’s about proving you have the skills to protect public health, comply with building codes, and deliver reliable service.

Becoming a licensed plumber opens doors to higher income, job security, and entrepreneurial freedom—all without student debt or a four-year degree. Whether you’re switching careers or starting fresh, this trade offers real opportunity for those willing to learn.
