Factors that impact the cost of plumbing insurance

Here are some of the top factors that impact the cost of plumbing business insurance coverage. Understanding them will help you gain control over your premium prices.

Size of the business

Larger plumbing businesses usually need more insurance coverage than smaller ones, which costs more. This doesn’t only apply to the number of plumbers, contractors, and other types of people who work for your company. If you have a relatively large client base, you face more risk of lawsuits and different kinds of claims, which will up your premium prices.


Different insurers calculate plumbers insurance premiums differently. And they may have different preferences (appetites) for covering plumbers. This will impact the quotes insurers provide. You owe it to yourself and your plumbing business to get quotes from several insurance companies to compare coverages and prices.

Claims history

If you’ve made claims on your plumbing business insurance, it’s a sign to insurers that you’re likely to file claims in the future. So, if you’ve made claims on your insurance in the past, you can expect to pay higher premium costs. 

Credit score

The credit score of the plumbing business owner can also impact premium costs. Credit scores are a measure of how reliable a policyholder will be in paying their insurance premiums. It also reflects how responsible people are. If you have a low credit score, you will likely pay more for insurance because you’re viewed as a greater risk. The reverse is also true: A high credit score can save you money on plumber insurance protection.

The type of plumbing you do

Plumbers that do dangerous outdoor work or projects in high-rise buildings will pay more for insurance than someone who does minor home repairs.

Business location

If your plumbing business is housed in a larger, more valuable space or at greater risk of fire losses. Also, some cities and states are known for their high rates of lawsuits. If you do plumbing work in one of them, you’ll pay more for insurance protection.

Limits and deductibles.

You’ll pay more for insurance with higher coverage limits. Also, if you select a higher deductible, you’ll pay less for coverage.

These aren’t all the factors that will influence your plumbing business insurance premium, but they’re among the ones that will have the most significant impact.

How to find cheap plumbing insurance?

Here are some tips to help you find the coverage you need at a reasonable cost:

  • Shop around. Get quotes from a few companies or compare the multiple quotes generated by a business insurance marketplace or broker. Work with a top broker like Simply Business, InsurePro, or CoverWallet is a good way to compare several quotes to choose the cheapest one for your business.
  • Take advantage of discounts. If they’re not offered to you when getting a quote, ask about them, whether you’re buying online or through an agent.
  • Choose the right coverage: As you know, there are several coverages a plumber would need. You don’t need all coverages. Make sure you only buy the coverage that you need the most. If you don’t know exactly the coverage you need, you may want to work with a knowledgeable agent or broker.
  • The right policy’s terms: Coverage limits and deductibles impact insurance rates in a significant way. Make sure you choose the right amount that works for your situation. Most policies has $1M coverage limit, but if you mostly work in some residential areas, you may not need $1M coverage, you can ask for a lower coverage limit such as $300K.

Taking these steps will help ensure you’re not paying too much for your plumbing business insurance coverage.
