Texas State Board of Plumbing Certificate of Insurance: Your Complete Guide

Why You Need a Texas State Board of Plumbing Certificate of Insurance (And What Happens If You Don’t)

If you’re a plumbing contractor in Texas, you’ve probably heard the phrase “Texas State Board of Plumbing Certificate of Insurance” — maybe even been told you need one. But what does it really mean? And why can’t you just skip it?

Here’s the truth: Operating without this certificate isn’t just a paperwork mistake — it’s a legal risk that can shut down your business, cost you thousands in fines, or even bar you from bidding on jobs. Whether you’re a new plumber just getting licensed or a seasoned pro renewing your credentials, this guide walks you through everything you need — clearly, step by step — so you stay compliant, protected, and in business.

Let’s get you covered — the right way.

What Exactly Is the Texas State Board of Plumbing Certificate of Insurance?

The Texas State Board of Plumbing Certificate of Insurance (COI) is an official document that proves your plumbing business carries the minimum required liability and workers’ compensation insurance as mandated by the Texas State Board of Plumbing Examiners (TSBPE).

This isn’t just a formality. It’s a legal safeguard — for you, your employees, and your clients.

Think of it like this:

If a pipe bursts during a job and floods a homeowner’s basement, your insurance pays for the damage. Without proof you have that coverage, the Board can’t approve your license — or renew it.

According to TSBPE’s 2024 Licensing Handbook, all active plumbing contractors and master plumbers must maintain liability insurance of at least $300,000 per occurrence and workers’ comp coverage if you have employees. The COI is the only accepted proof.

“Insurance isn’t optional — it’s the foundation of trust between contractors and the public,” says Dr. Linda Ruiz, former TSBPE advisory board member. “Clients don’t just want a good plumber. They want one who’s accountable.”

Who Exactly Needs This Certificate?

Not every person working with pipes needs it — but if you’re running a business, you do. Here’s who’s required:

Important: Even if you’re a solo plumber with no staff, you still need the $300,000 general liability policy. No exceptions.

Step-by-Step: How to Get Your Texas State Board of Plumbing COI (2025 Guide)

Getting your COI is simple — if you know the steps. Follow this 5-step process:

Step 1: Choose a Licensed Texas Insurance Provider

Not every insurer covers plumbing contractors. Use only providers licensed by the Texas Department of Insurance (TDI).
👉 Tip: Search TDI’s licensed agent directory: https://www.tdi.texas.gov

Step 2: Purchase the Minimum Required Coverage

• General Liability Insurance: Minimum $300,000 per occurrence
• Workers’ Compensation Insurance: Required if you have 1 or more employees (even part-time)
• Optional but recommended: Pollution liability, tools & equipment coverage

💡 Real Example: In 2023, a Houston plumber was fined $5,000 and suspended for 60 days because his COI showed only $100,000 coverage — below the state minimum.

Step 3: Request Your Certificate of Insurance

Ask your insurer for a Certificate of Insurance (COI) — not just a policy summary.
Make sure it includes:

• Your business name and address
• Policy number and effective dates
• Coverage limits ($300K+)
• Named insured: Your business name (not your personal name)
• TSBPE listed as “Additional Insured” (critical!)

⚠️ Warning: If TSBPE isn’t listed as an additional insured, your COI will be rejected.

Step 4: Submit to the Texas State Board of Plumbing

Log in to your account at the TSBPE Online Licensing Portal:
👉 https://www.tsbpe.texas.gov

Go to “License Renewal” or “New Application” → Upload your COI under “Proof of Insurance”.
You’ll get an email confirmation within 3–5 business days.

Step 5: Keep It Current

Your COI expires when your policy does — usually annually. Set a calendar reminder 30 days before renewal.
Late submission = license suspension. No grace period.

COI vs. General Insurance: What’s the Difference?

Many plumbers confuse their insurance policy with the COI. Here’s the clear breakdown:

Think of it this way:

Your insurance policy is your shield. The COI is the receipt that proves you bought it.

What Happens If You Don’t Have a Valid COI?

Ignoring this requirement isn’t worth the risk. Here’s what TSBPE can do:

• Deny your license application outright
• Suspend your active license (no work allowed)
• Impose fines up to $5,000 per violation
• Publicly list you as non-compliant on their website
• Bar you from bidding on public projects (schools, hospitals, government buildings)

In 2023, 147 plumbing licenses were suspended in Texas for missing or invalid COI documentation — according to TSBPE’s annual enforcement report.

“We see it every month,” says Carlos Mendez, TSBPE Compliance Officer. “Plumbers think, ‘I’ve been doing this 10 years — I don’t need to check.’ Then they get a call saying their license is inactive. They lose jobs, clients, and income.”

Don’t be one of them.

FAQ: Texas State Board of Plumbing Certificate of Insurance — Answered

Q1: Can I use my home insurance for my plumbing business?

No. Homeowners insurance explicitly excludes commercial activities. Using it for your plumbing business voids coverage and will get your COI rejected. You need a commercial general liability policy designed for contractors.

Q2: Do I need workers’ comp if I’m a sole proprietor with no employees?

No — but you still need $300,000 general liability. Workers’ comp is only mandatory if you hire even one person — including family members or part-time helpers.

Q3: How long does it take to get a COI after purchasing insurance?

Most insurers issue the COI within 24 hours after payment. Some offer instant digital copies via email. Always request it in PDF format and keep a backup.

Q4: Can I submit a COI that expires next month?

No. Your COI must be active and valid on the date you submit. If your policy expires in 15 days, your application will be denied. Always ensure coverage extends at least 30 days beyond your submission date.

Q5: What if I make a mistake on my COI?

If your COI has errors (wrong business name, wrong limit, missing TSBPE), do not submit it. Contact your insurer immediately for a corrected version. Submitting a flawed COI delays your license and may trigger a compliance review.

Q6: Does the Texas State Board accept electronic COIs?

Yes! TSBPE only accepts digital uploads via their online portal. Paper copies, faxes, or emailed PDFs sent directly to their office are not accepted. Always use the official portal.

Pro Tips to Avoid Common COI Mistakes

Here’s what seasoned Texas plumbers wish they knew earlier:

• ✅ Double-check the named insured — it must match your business name on your license.
• ✅ Always list TSBPE as “Additional Insured” — this is the #1 reason for rejection.
• ✅ Don’t wait until renewal time — get your COI early. Insurance providers get busy in December.
• ✅ Save a copy — keep a digital AND printed version in your file. You may need it for client contracts too.
• ✅ Verify your insurer’s TDI license — avoid scams. Check here: https://www.tdi.texas.gov

“One client came to me with a $4,000 fine because their COI said ‘John’s Plumbing’ instead of ‘John’s Plumbing LLC.’ One typo. One month without work.”
— Ricky Torres, Texas Plumbing Consultant
