Getting Started
Not everything on a coverage checklist matters the moment you open. Here's what to get before your first job, and what can reasonably wait.
General liability isn't optional for a new plumbing business the way some other coverage can be phased in. One claim from your very first job — a fitting that fails and floods a client's kitchen — can end a business before it's had a chance to get going. Even with zero jobs completed and zero claims history, GL with completed operations built in is the coverage to have in place before you ever pick up a wrench for a paying customer.
Workers compensation doesn't apply until you have employees, so a solo operator doesn't need to think about it on day one — just revisit it the moment you make your first hire. Tools and equipment coverage can also wait briefly if you're starting with a minimal kit that would be cheap to replace out of pocket. That changes fast, though: the day you buy a press tool, a sewer camera, or a jetter, that calculus is over and it's worth adding equipment coverage right away. Commercial auto only matters once you're using a dedicated work vehicle rather than your personal truck for the occasional job.
A common mistake is assuming licensing comes first and insurance can follow once the business is actually running. In many jurisdictions it's the reverse — proof of insurance is required before a permit office will even issue your first permit, and sometimes before your contractor license is finalized at all. Check what your specific state and municipality require on our insurance requirements by state page before you assume you have more runway than you actually do.
Carriers can't rate a brand-new business the same way they rate an established one with years of clean claims history behind it — that history simply doesn't exist yet. Instead, pricing leans more heavily on your projected revenue and the type of work you plan to take on. Being upfront and realistic about projected volume when you request a quote avoids an unpleasant surprise at your first renewal, when actual revenue gets compared against what you originally estimated. See our cost breakdown for what a first policy typically runs.
The most expensive mistake new plumbers make isn't skipping insurance entirely — it's underinsuring completed operations to shave a few dollars off the monthly premium, without realizing that's exactly the coverage most likely to get triggered early on. A first repipe or water heater install that fails weeks after the job is finished is a completed-operations claim, and it's disproportionately common in a business's first year simply because everything is new: new processes, new suppliers, new judgment calls made under time pressure. Our general liability page goes deeper on why this piece of the policy matters more than people expect.

FAQ
Often yes — many permit offices and licensing boards require proof of active general liability before they'll issue your license or your first permit, not after. Check your specific state's requirements before assuming licensing comes first.
Yes. New businesses are rated on projected revenue and the type of work planned rather than loss history, since there isn't one yet. Being accurate about your projected volume avoids a surprise at renewal.
Starting with general liability alone, before adding tools coverage or other add-ons, keeps first-year cost lowest — but completed operations should stay built in regardless, since that's the coverage most likely to matter early on.
No — workers comp becomes relevant the day you bring on your first W-2 employee, not before. As a solo operator, it doesn't apply to your own business yet.
As soon as you own gear that would be expensive to replace out of pocket — a press tool, sewer camera, or jetter changes the math immediately, even if you started without needing it.
