Why Did My Commercial Insurance Premium Increase, and What Can I Do About It?

There's something unusual about asking that question in 2026.

For most of the past nine years the answer was easy, because rates were going up across the board and if your premium climbed, so did everyone else's. That's no longer true. The market turned soft in early 2026, with average premiums declining across all account sizes for the first time since the third quarter of 2017 and ending a 33-quarter run of increases.

So if your renewal still came in higher, the market isn't the explanation anymore. Something in your file is, which is actually good news, because the things in your file are the things you can change. Before getting to those, though, it helps to know what the baseline looks like.

The Short Version

Commercial insurance premiums are set by combining your industry classification and exposure base with your own loss history, then adjusting for carrier appetite and market conditions. Some of those inputs are outside your control. Your claims history, risk controls, property valuations, and the quality of your submission are not.

What's Actually Happening in the Market Right Now

The softening is real, and it accelerated over the course of the year. After the 1.2 percent average decline in the first quarter, premiums fell another 2.0 percent in the second. Commercial property led the way down at 6.3 percent, its fourth consecutive quarterly decrease, helped along by a surplus of capacity that three quarters of surveyed brokers reported seeing. Cyber and workers' compensation each came down 3.2 percent.

But that relief wasn't evenly distributed, and the exceptions are where most businesses actually live.

Commercial auto and umbrella kept climbing straight through it. Umbrella rose 5.3 percent in the second quarter, its 35th consecutive quarterly increase, driven largely by the frequency and size of nuclear verdicts. Commercial auto rose 4.5 percent after leading all lines with a 5.8 percent increase the quarter before, and it has now posted increases every quarter for nearly five years, pressured by distracted driving, congested roads, medical costs after an accident, and the price of repairing vehicles packed with technology.

Account size shaped the picture too. Large accounts saw premiums fall 3.7 percent in the second quarter and medium accounts fell 1.9 percent, while small accounts came down just 0.5 percent after actually rising 1.1 percent in the first.

Put those together and something clarifies. If you're a smaller business with vehicles on the road, you sat in the two segments that felt the least relief. That doesn't make your increase inevitable, but it does mean the market gave you less cover than it gave someone else, and the rest is down to your file.

The Factors You Can't Control

Before getting into that file, it's worth naming the things that genuinely aren't yours so you can set them aside.

• Carrier appetite. Insurers periodically decide they want more or less of a given class of business, and those shifts move your price without anything changing on your end.
• Reinsurance costs and capacity. What carriers pay to offload risk flows down to what you pay.
• Catastrophe losses. Storm and wildfire activity affects property pricing far from where the losses occurred.
• Social inflation and litigation trends. Rising jury awards and settlement values push liability lines up regardless of your own claims record.
• Your class code and geography. Roofers pay more than accountants, and that isn't negotiable.

None of this is your fault, and none of it is worth much of your attention. Which is precisely why the rest of this article is about the part that is.

The Factors You Can Control

Direct answer: Four inputs are genuinely within your reach: your claims history and open reserves, your documented risk controls, your property valuations and coverage structure, and the quality of the submission your broker takes to market. Each one moves your price, and each one takes months rather than weeks to change.

Claims history

Start here, because it's the biggest of the four and considerably more adjustable than most owners realize. Your claims history follows you for three to five years, and the report carriers price you on almost always contains something worth fixing.

Open reserves are usually the culprit. A claim that settled for $5,000 but still carries a $40,000 reserve gets priced as a $40,000 claim until somebody closes the file or challenges the number. So if you've never gone through your loss run line by line, that's the first place to look, and we've written a full walkthrough on how to read a loss run report and what an underwriter takes from yours.

For workers' compensation, all of that feeds directly into your experience modification rate. NCCI's ABCs of Experience Rating lays out the mechanics, where below 1.00 is a credit and above 1.00 is a debit, and it also explains why a workers' comp premium can rise even when your claims went down, which catches a lot of people off guard.

Risk controls, documented

The second lever is easier to miss, because it isn't about having safety programs. It's about being able to prove you have them, and only one of those two affects your premium.

Underwriters price what they can verify, which means training records, written procedures, telematics data, maintenance logs, and return-to-work programs all count for something, but only when they actually show up in the submission. For a sense of where you stand, the Bureau of Labor Statistics put private industry at 2.3 recordable injury and illness cases per 100 full-time equivalent workers in 2024, the lowest figure in a series going back to 2003. So if you're running above your industry rate, that's a number worth working on, and the return on workplace safety training tends to show up in more places than premium alone.

Valuations and structure

Third, and often the most out of date. Property valuations drifted badly during the construction cost spike, so a lot of buildings are still insured at numbers that don't reflect replacement cost, and that cuts both ways. Under-insured means a coinsurance penalty at claim time, while over-insured means paying for limits you don't need.

Deductibles, retentions, and coverage structure belong in the same conversation. Raising a deductible isn't automatically the right answer, but it should at least be modeled rather than assumed.

Submission quality

The last of the four is the one nobody talks about, and it may be the largest.

An underwriter looking at your account has a limited window and a stack of other submissions competing for it. So a file that arrives with clean data, a clear narrative, documented controls, and answers to the obvious questions gets priced differently than the same risk sent over as a bare application and a loss run. Not out of favoritism, but because uncertainty gets priced conservatively and a good submission removes it.

What Should Your Broker Be Doing About Rising Insurance Costs?

Since three of those four levers involve someone doing work on your behalf, it's a fair question to ask out loud, and the answers vary more than you'd think.

A transactional broker markets your account. They take what you give them, send it to several carriers, and bring back the lowest number. That's a real service, and in a soft market it can produce a decent result.

An advisory broker works on the inputs before anything goes to market. They review your loss run mid-year and challenge stale reserves, help you document controls that would otherwise go unmentioned, check valuations before an underwriter does, and tell you which of your lines are softening and which aren't so you know what a fair renewal even looks like. Then they build a submission that explains your business rather than just describing it.

The difference between those two shows up most clearly in a year like this one. Shopping a mediocre file in a soft market gets you the market's discount. Improving the file first gets you the market's discount plus your own.

What Most Companies Do Versus What Proactive Companies Do

Laid out side by side, the habits behind those two outcomes look like this.

	Most companies	Proactive companies
When work starts	30 to 60 days before renewal	Mid-year, then again at 120 days
Loss runs	Forwarded to the broker unread	Reviewed line by line, reserves challenged while claims are open
Safety programs	Exist, undocumented	Documented and included in the submission
Valuations	Rolled forward from last year	Reviewed against current replacement cost
Response to an increase	Shop the account	Fix the inputs, then shop the account
Market knowledge	Whatever the renewal letter says	Know which lines are softening and what a fair number looks like
The submission	Application and loss runs	A file that explains the business and answers questions before they're asked
Deductibles	Same as last year	Modeled against actual claim frequency

The Question Worth Asking This Year

Which brings the whole thing back to how you respond when a renewal comes in high. Most businesses ask whether they can get a better price somewhere else, and in 2026 there's a sharper question available.

The market handed out an average decrease this year. Did you get one?

Because if your renewal came in flat, that's a quiet increase, since the baseline moved down around you. And if it came in up, something specific is driving it, which is almost always identifiable: bad reserve data, a frequency trend nobody addressed, valuations that never got updated, or simply a file that didn't explain itself well enough to earn the benefit of the doubt.

None of those get solved in the last three weeks before a renewal, but all of them are solvable with a couple of quarters of lead time. Which is the whole argument for working on this year-round, and why we start renewal preparation 120 days out rather than at the deadline.

Where Prevent365 Fits

That approach is what the second stage of Prevent365, Differentiate Your Business, is built for.

Differentiating means giving an underwriter a reason to price you as better than your class code suggests, which isn't a marketing exercise so much as an evidence-gathering one. It means a claims history that's been actively managed, controls that are documented rather than assumed, valuations that hold up under scrutiny, and a submission that answers the questions an underwriter was going to ask anyway.

Businesses that do that work don't get a discount because they asked nicely. They get one because they showed up as a better risk than the next file in the stack.

Frequently Asked Questions

Everyone says commercial insurance rates are falling. Why did mine go up?

The softening isn't uniform. Commercial auto and umbrella kept rising through 2026 while property, workers' comp, and cyber came down, and small accounts saw far less relief than large ones. If your program leans on the lines that were still climbing, or if your loss history worsened, an increase in a soft market is entirely possible. What's changed is that the market alone no longer explains it.

Should I shop my policy after a premium increase?

Shopping is worth doing, but usually second, not first. Marketing a file with stale reserves, undocumented controls, or outdated valuations sends every carrier the same weak submission and produces a narrow range of quotes. Fix what's fixable, then go to market. In a competitive year, an improved file gets you the market's discount on top of your own.

How far in advance do I need to start to actually change my renewal?

Four to six months for meaningful movement. Reserve challenges take weeks to work through a carrier. Documenting safety programs takes time. Valuation updates need to be reflected before your submission goes out. Starting at 30 days limits you to shopping the file you already have, which is the least effective lever available.

Does raising my deductible actually save money?

Sometimes, but it should be modeled rather than assumed. The savings depend on how often you actually have claims in that range. A business with frequent small claims may pay more in retained losses than it saves in premium, while a business with clean frequency may find a higher deductible is close to free money. Look at three to five years of claim counts by size before deciding.

What factors drive commercial property insurance premium increases specifically?

Replacement cost valuations, construction type, protection class, catastrophe exposure, and your own property loss history are the main drivers. Valuations have been the biggest recent mover, since construction costs outran many stated values. With property capacity now expanding and rates falling, this is the line where an accurate, well-documented submission has the most upside.

How can contractors lower commercial insurance premiums?

Focus on the experience modification rate, subcontractor certificate tracking, and fleet safety, in that order. The mod affects workers' comp pricing and often gates prequalification for larger projects. Uninsured subcontractors get charged back to your policy at audit. And commercial auto is the one line that hasn't softened, so telematics and documented driver programs carry real weight right now.
