The state-created insurer and the private market: how Colorado comp actually gets placed
The honest answer is that Colorado workers’ comp is a two-door market. One door is a state-created insurer that, under current law, has to let you in. The other door is a group of private carriers that get to choose, and they choose on your trade, your payroll, your years in business, and your loss runs. A first-year excavation outfit usually walks through the first door because the second one doesn’t open yet. Three clean years later, the second door is where the interesting quotes come from. The workers compensation page explains what the policy does. This article is about where the policy comes from, why a brand-new trenching crew gets placed where it does, and what actually moves an account across.
The state-created insurer, as the statute describes it
Colorado has one workers’ comp insurer that exists because the legislature created it. Here’s the fact as we track it, with its citation and a verify badge, because the status is in motion right now.
Pinnacol Assurance, a state-created political subdivision that operates as a mutual insurer, may not refuse to insure any Colorado employer because of risk or premium size (C.R.S. 8-45-101(5)(f)), which is why agents call it the carrier of last resort. (C.R.S. 8-45-101(1), (5)(f)) [VERIFY]Read that carefully. It is a description of a legal duty, not a recommendation. The insurer named in the statute must offer a policy to any Colorado employer regardless of how risky the operation is or how small the premium would be. That duty is the reason a one-truck utility trenching outfit with no track record can, under current law, get a workers’ comp policy in this state when the coverage requirement kicks in at 1 employee .
Two things to keep straight about that badge. First, a bill to convert the insurer to a different structure stalled in the 2026 session, and a ballot initiative proposing conversion is pending. Second, the duty to offer coverage is what it says today, and nothing about your policy changes until a law does. We’ll keep the fact updated. Until then, treat the “must insure” line as current and the future as unsettled.
We don’t name carriers on this site, and we’re not naming one here beyond what the statute requires to explain how the market works. Nothing on this page is a recommendation to buy from any particular insurer.
Why the private market says no to a new dirt outfit
Private carriers write workers’ comp for contractors in Colorado. Plenty of them. What they don’t tend to write is a first-year excavation, tree, or demolition venture, and the reasons are boring rather than personal.
An underwriter prices a comp policy on payroll times a rate per class, then adjusts for what your history says about you. A new venture has no history. Its payroll estimate is a guess. Its class mix (excavation, some landscape install, snow in winter) is the kind that gets rated in several codes, and those codes are typically among the higher-rated ones the trades use. In our trades the codes are commonly 0042, 9102, 6217, 0106, 9402[VERIFY] , and the carrier makes the final assignment; that fact carries its own verify badge because one of the codes is still being confirmed against NCCI’s own documents.
Put those together and the file reads: high-hazard class, unknown payroll, unknown loss behavior, small premium. Some private carriers will quote it. Most won’t in year one, and the ones that do often want a payroll floor or a minimum premium the small crew can’t reach. That’s not a judgment on your operation. It’s what the file looks like from a desk in an office that has never seen your trench box.
So the new outfit gets placed with the state-created insurer, or with the one or two private carriers that write new ventures in construction, and the decision between those is a quote comparison, not a rule.
NCCI sets the framework both doors use
Whichever door you walk through, the rating rules are the same, because Colorado is an NCCI state.
NCCI is a licensed rating organization authorized to make recommended loss cost filings on behalf of workers' compensation insurers in Colorado; the Colorado Division of Insurance approved NCCI's filing for an average loss cost change of -6.9% effective January 1, 2026 (Order O-26-010). (NCCI Colorado State Advisory Forum 2025; Colorado DOI Order O-26-010 (Oct. 27, 2025))That matters for three reasons. The class codes on your policy are NCCI’s. The experience rating that eventually follows you is NCCI’s. And the loss costs that every carrier starts from are NCCI’s filed numbers, with each carrier applying its own multiplier on top. The percentage change in that fact is a dated filing that moves every year; the durable point is that the framework is shared. Two carriers quoting the same crew are starting from the same class and the same loss cost and disagreeing about the multiplier, the credits, and whether they want the account at all.
That’s also why “cheaper carrier” is the wrong way to think about the choice. The private carrier and the state-created insurer can quote the same grading crew differently in either direction depending on the year, the class mix, and what the carrier’s book of construction looks like that season. We don’t control that. The way to choose is to put the quotes side by side and read them.
What moves an account to the private market
Here’s what we tell every contractor who asks. The private market opens on paper, and the paper takes about three years to build.
Loss runs. Carriers typically want to see several years of claims history before they’ll price an account with confidence. A clean run is good. A run with one small claim, reported promptly and closed, is often fine too. What hurts is an open claim with a big reserve, or a pattern of the same injury. The loss runs article explains how to read yours before an underwriter does.
Payroll size. An account has to be worth an underwriter’s time. A crew of two with seasonal payroll is a small premium in a high-hazard class, which is the combination private carriers avoid. A crew of eight with year-round work is a different file.
An experience mod. Once payroll and premium reach NCCI’s eligibility threshold (the number is in NCCI’s rules and depends on the state, so we won’t quote it here), the account gets an experience modification. A mod below the class average is the single strongest signal a private underwriter reads. It’s also the number that takes the longest to earn, because it’s built from prior years.
Settled owner status. Underwriters want to know who is in and who is out before they price it. 10% owner may reject; sole proprietor may elect in . The election has to be filed properly with the carrier, and an owner who runs the Yanmar mini skid steer all day is a different exposure from one who runs the office. Get this decided before you shop, not during.
A safety program in writing. A one-page trench safety plan, a competent-person designation, a toolbox-talk log, and drug testing. Not because the underwriter reads every page, but because the file with the program and the file without it are priced differently.
Class mix the underwriter understands. A landscaper who also plows Denver HOAs, a septic installer who also does demolition, a tree service with a crane: each combination needs to be described honestly, with payroll split by task, so the quote is for the operation you actually run. Mis-describing it to get a better number gets found at audit, and the audit bill follows you to the next carrier.
What the placement doesn’t change
The policy is the policy. Colorado workers’ comp benefits are set by statute, not by the carrier, so an injured operator gets the same medical care and wage replacement under a state-created insurer’s policy as under a private one. The differences show up in premium, in the services around the policy (safety consulting, return-to-work help, audit style), and in how the carrier handles a claim from the first phone call.
That last one matters more than people expect. A carrier that returns the adjuster’s call the same day and gets your foreman into a clinic that afternoon is worth something when you’re a crew of five and he’s the one who runs the mid-size excavator. Ask about claim handling before you switch for a small premium difference.
Also: none of this touches general liability. Comp is the injured-worker policy. The gas line your trencher hits, the retaining wall that leans, the neighbor’s fence the machine rolled through are GL claims and they live on a different policy with a different carrier, or the same one, depending on how the package is built.
What a new contractor should do this month
If you’re hiring your first employee, the one-employee article covers the trigger and the penalties. Then do four things in this order.
- Decide the owner election under Colorado’s rules and get the form filed with the carrier, not stuck in a drawer.
- Estimate payroll honestly by class, with the seasons split. A guess that’s low is a loan you repay at audit.
- Write the one-page safety plan and start the toolbox-talk log the same week. It’s cheap and it’s on every underwriter’s list.
- Call us before you apply anywhere. A new-venture application that’s been declined by three carriers is harder to place than one that went to the right carrier first.
Then keep the policy in force, keep the records, and let the file build. In Park County, where the working season is short and the payroll is lumpy, that patience is the difference between an account the private market wants and one it keeps passing on.
Where to go from here
If you’re placed with the state-created insurer and think you’ve earned a look at the private market, send us three years of loss runs and your current dec page. If you’re new and haven’t bound anything yet, call (720) 529-0300 and we’ll walk the application before it goes anywhere. Either way, getting insured starts with the same two questions: who is on the payroll, and what do they actually do all day.
