Your price is built from your numbers, not an average.

Spread the annual premium across the year and add whatever installment fee the carrier charges, which is the honest answer, because the policies are priced annually on your payroll, revenue, vehicles, and tool values, then billed on a schedule. Monthly billing does not change the price; it spreads it. What changes the answer is the shop behind the question: a solo service plumber and a large commercial outfit both ask it and land far apart, and both are priced correctly. The factor list on this page is how to see where your shop sits before a quote comes back.

Because it is rated on payroll, and payroll is the largest number most plumbing shops have. Every dollar of field payroll carries the plumbing class rate for your state, and the rate reflects the injuries the trade actually has: lifting, stairs, trench work, burns, cuts. Office and sales payroll carry lower rates, which is why the split matters. What changes the answer is how the payroll is classed and whether subcontractors carry their own coverage, since uncertificated subs can be added to your payroll at the audit as if they were employees.

Usually, and how much depends on the size of the claim, whether it is closed, and what changed afterward. Carriers look at several years of loss runs and price the account on frequency more than on a single severity: three small water-damage claims read worse than one larger one with a documented fix. Workers’ comp adds an experience modifier in most states once the account is large enough, which moves the rate up or down from the base. What changes the answer is what you can show changed since: new training, a jetter camera policy, a driver review. A closed claim with a fix behind it is a different account from an open one.

Sometimes, and sometimes it costs more, which is why we do not assume it. A business owner’s policy that packages general liability with property can be cheaper for a shop that qualifies, and some carriers discount auto alongside it. Workers’ comp is often priced better on its own by a specialist market, and tools and equipment can come from a third. The cheapest program is the one where each line is placed where it prices best, then managed as one account. What changes the answer is your mix of lines and your state, so we price both ways and show you the difference.

A few things, all of them paperwork rather than coverage cuts. Class your payroll correctly and keep the office and sales split documented. Collect certificates of insurance from every subcontractor before they start, so none of their payroll lands on your audit. Keep a driver list current and remove anyone who no longer drives for the shop. Schedule the tools you actually own at values you can support, and drop the ones you sold. Then send loss runs early so the renewal is priced on the full picture. What changes the answer is how early we see it, since a renewal quoted the week it is due gets the fewest markets.

Online estimates are built from averages across many trades and shops, and averages are not a rating basis. A real quote is built from your payroll by class, your revenue by work type, your vehicles and drivers, your tool values, and your claims. Any one of those can move the number well away from a published figure in either direction, which is why this page does not print one. What changes the answer is your inputs, so the estimate and the quote agree only by accident. Send the checklist and the first number back is the real one.
