Plumber insurance: what you need and what it costs

Updated 2026-05-01

Plumbers face some of the highest liability exposure of any trade — water damage claims are frequent, expensive, and can hit six figures fast. GCs won't let you on a job site without a COI. Most states won't issue a plumbing license without a bond. Here's exactly what you need and how to get covered quickly.

Short version: Plumbers typically pay $800–$1,400/year for GL insurance and $100–$400/year for a surety bond. Both are required for most state plumbing licenses. You can bind online and download a COI the same day.

What insurance does a plumber need?

Coverage	What it covers	Required?	Typical cost
General liability	Property damage and bodily injury from your work	Yes — for licensing and GC jobs	$800–$1,400/yr
Surety bond	Guarantee to state/clients you'll follow laws and complete work	Yes — most state licenses	$100–$400/yr
Workers' comp	Employee injuries on the job	Yes, if you have employees	Varies by state/payroll

What general liability covers for plumbers

GL is the policy that clients and GCs ask for. It covers:

Water damage to a client's home caused by your work (burst pipe, failed fitting, overflow)
Bodily injury — a client trips over your equipment or tools
Property damage during the course of your work
Legal defense costs if you're sued

Most GCs require $1M per occurrence / $2M aggregate. Some commercial and municipal contracts require $2M per occurrence. Verify requirements before accepting a job.

Do plumbers need a surety bond?

In most states, yes — a surety bond is required to get your plumbing license. The bond protects the state and your clients if you fail to complete contracted work, violate licensing laws, or don't pay subcontractors. It is not the same as insurance and one does not replace the other.

Typical plumbing license bond amounts: $5,000–$25,000. Annual premium: $100–$400 depending on bond amount and your credit. Good credit = lower premium.

GL pays for these. Without it, they come out of your pocket — or your personal assets.

Frequently asked questions

How much does plumber insurance cost?

General liability for a self-employed plumber typically runs $800–$1,400/year for $1M/$2M limits. Factors: state, annual revenue, number of employees, and claims history. Plumbers pay more than painters or handymen because water damage claims are frequent and expensive. You can bind online and get a COI the same day.

Does a plumber need a surety bond?

In most states, yes — a plumbing license requires a surety bond on file with the state licensing board. Bond amounts range from $5,000–$25,000 depending on state, and annual premiums run $100–$400. The bond protects clients and the state if you fail to complete work or violate licensing laws. It is separate from your liability insurance.

What insurance do plumbers legally need?

Requirements vary by state, but most plumbers need: GL insurance to get licensed and pull permits, a surety bond for state licensing, workers' compensation if you have employees, and commercial auto if you use a vehicle for work. Some municipalities also require inland marine to cover tools and equipment on job sites.

Does plumber's GL cover water damage?

GL covers water damage you cause to someone else's property during your work — for example, a pipe you installed bursts and floods a customer's kitchen. It does not cover damage to your own tools or equipment (that's inland marine), and it doesn't cover faulty workmanship itself — just the resulting damage.

Can a plumber get insurance without a license?

Yes — you can get GL insurance as an unlicensed handyman or plumber's helper, but you cannot pull permits or perform licensed plumbing work without a license. Some carriers ask about licensing status and may limit coverage for work that requires a license if you don't have one.

How fast can I get a plumber's certificate of insurance?

With online carriers you can bind a policy and download a COI within minutes. Most GCs and municipalities accept digital COIs. If you need to add a GC or property owner as an additional insured, that's usually free and instant as well.
