Tree Service Insurance Cost: What You Can Change

Underwriters, the people at the insurer who decide whether to write a policy and at what price, look closely at five things on a tree service company: workers' compensation payroll, the mix of work the crews do, the heavy truck fleet, the claims history, and how complete the submission looks. A new owner can influence several of these through records, the safety program, paperwork and work mix, which are the parts an underwriter can actually see. This guide shows which to work on first. It gives no prices, because rates vary by state, carrier and your own history. It is written for a buyer who wants to protect cash flow and debt service without cutting coverage that matters.

The short answer

Levers a new owner can pull include workers' comp payroll and how it is split between class codes (the rate categories for different kinds of work), the experience mod (a score that compares your claims history with similar companies and adjusts your premium), the mix of work (removal, pruning, crane, spraying, storm), the fleet and the claims history.
One trade author says underwriters fill missing information with cautious assumptions, so a complete submission, sent 90 to 120 days before renewal, helps.
Documented safety training, driver screening, written subcontractor agreements and credentials can matter to some carriers.
You cannot change the seller's loss history, but you can ask the adjuster to review stale open claims, correct records and show what you changed.

Why do insurers treat tree work as high hazard?

The injury data show why tree work is treated as high hazard. The Bureau of Labor Statistics (BLS) put the 2024 fatal injury rate for landscaping services, the industry code that includes tree companies along with lawn and garden companies, at 18.5 deaths per 100,000 full-time equivalent workers, with a margin of error of 1.28. For all workers it was 3.3. That figure mixes tree and lawn work, so it describes the trade and not tree crews alone. The nonfatal gap is narrower: the 2024 recordable injury rate for landscaping services was 3.0 cases per 100 full-time workers, against 2.3 for private industry.

BLS counts 70,600 tree trimmer and pruner jobs out of 1,299,200 grounds maintenance jobs in 2025 (about 5 percent), but 99 of the 239 grounds maintenance deaths in 2024. Those are different years, so treat the comparison as approximate. A trade magazine article by an insurance professional puts it plainly: tree care is one of the most hazardous industries and carriers price it accordingly. That does not mean every account is priced the same. It means underwriters look closely at the things below.

What do underwriters price, and what can you do about each driver?

Tree service company cost drivers, why they matter and what a new owner can influence
Cost driver	Why it matters	What you can do
Payroll and class split	Workers' comp premium is generally a state-approved rate per $100 of payroll in each class, with the mod then applied. Tree, lawn and office payroll can sit in different classes	Keep time and pay records by class so a split can be proven at audit. The workers' comp and payroll guide for tree companies shows how
Experience mod and open claims	The mod is a multiplier on workers' comp premium. A mod of 1.0 is average, and above 1.0 adds a surcharge (very small companies may have no mod). Open claims count at their reserves	Review the mod worksheet for errors and ask the adjuster about stale reserves
General liability exposure base	General liability is commonly priced on a measure of exposure such as payroll or revenue, adjusted for the work mix and completed operations history	Ask the broker which base your policy uses, check it against your real numbers and update it when the business changes
State and rating bureau	Workers' comp rates, class rules and mod rules are set state by state, and four states (North Dakota, Ohio, Washington and Wyoming) use monopolistic state funds	Ask for the class rates and rules for every state where crews work, including storm work in other states
Mix of work	Removal, pruning, plant health care, crane or rigging use, line clearance and storm work carry different hazards. Underwriters also read websites, and services listed but rarely done can create exposure	Describe the real mix honestly, match the website to the crews' real work, and update both when the mix changes. The coverage gaps guide for tree companies shows where a new work mix can open a gap
Fleet and drivers	Chip trucks, dump trucks, bucket trucks and trailers raise auto cost, and commercial driver's license (CDL) rules apply to heavy units	Remove units you do not use, check driving records and keep medical certification files current
Equipment values and age	Chippers, grinders, lifts and cranes drive inland marine premium, and older units may be insured at actual cash value	Keep a current schedule and drop sold or scrapped units
Yard, shop and contents	Property premium follows the values insured and what is stored, including fuel	Insure to a current replacement estimate, not the deal price, and match the description to how the yard is used
Subcontractors	Uninsured crews can be charged to your workers' comp audit and create injury exposure	Collect certificates and signed agreements before work starts. See the same workers' comp guide for how an uninsured climber reaches your audit
Safety program and credentials	Some carriers treat written programs, training records, driver screening, certified arborists and company accreditation as credit criteria	Document training and screening, and show who holds credentials
Contract requirements and limits	Additional insured, completed operations and umbrella asks can raise cost	Read each major contract against the policy before renewal
Limits and deductibles	Higher deductibles can lower premium but move cash risk to you	Model the cash impact before choosing

The workers' comp cost guide, the commercial auto cost guide and the inland marine cost guide explain the general mechanics behind each line.

Which drivers can a new owner change in the first year?

Sort the table by how fast each item moves.

Fast (this renewal): the submission itself, the equipment and vehicle schedules, the website, certificates from subcontractors, and the class split records. These cost time, not premium.
Medium (one to two renewals): a written safety program, documented training, driver screening with motor vehicle records and a drug and alcohol testing program, and telematics (vehicle tracking and driving-behavior monitoring) or driver standards. See safety programs and premium credits and fleet telematics and driver standards.
Slow (years): the experience mod. The National Council on Compensation Insurance (NCCI) uses three years of loss history and leaves out the most recent completed year, so the seller's years follow you for a while. See reviewing the experience mod for errors.
Open claims: stale reserves count in the mod. See closing old open claims on loss runs, and ask your broker whether a lower reserve changes a mod already issued, because that depends on the rating organization's revision rules.

For your model, treat premium as a range until the first audit and the first renewal narrative are done. The audit mechanics are in the workers' comp guide for tree companies.

Be careful with deductible changes. Raising a deductible shifts claim dollars from the insurer to your cash flow, and raising deductibles after an acquisition covers the trade-off.

What happens to the price when your work mix changes after the sale?

Underwriters price what they are told the business does, so a change in work is a pricing event even when nothing has gone wrong. Crane use, taller removals, storm cleanup near lines and extra drivers each change what a carrier is asked to insure.

A hypothetical example. A buyer of a pruning-heavy company begins taking crane-assisted removals and storm cleanup near lines. The broker's narrative lists the new work mix, the maximum tree height, the crane or lift rental terms and the extra drivers, and the equipment and vehicle schedules are updated. If the old description stays on file, the policy is priced for work the company no longer does, and the carrier may find the difference at audit or at claim time. What each carrier does varies, and no outcome is assured. The guide to what underwriters want from new owners shows how to frame a change like this.

What should your broker send insurers at renewal, and when?

The renewal submission is the package your broker sends insurers. One tree care insurance article recommends sending the submission 90 to 120 days before renewal, and warns that an incomplete submission gets priced for the worst version of your business. Another notes that carriers also use supplement questionnaires, including crane and lift questionnaires, and loss-control visits. A typical package includes:

Five years of up-to-date loss runs (the insurer's claim history reports) for every line
Financial statements and payroll by class code
An equipment schedule and a vehicle schedule with vehicle identification numbers (VINs) and driver lists
Signed subcontractor agreements and certificates
Safety documentation, training records and credentials
A short narrative from the broker that explains the changes since the sale

The narrative matters most in the first renewal after a purchase, because the loss history belongs to the seller's era and the operations belong to yours. If you want a second set of eyes on the package before it goes out, Morrow can review the declarations pages and loss runs you inherited.

What should you not try to cut?

Cutting the wrong line trades a visible premium for an invisible risk. Crane and equipment coverage, completed operations and the umbrella can look like easy places to trim, and a customer contract may require some of them. If you consider dropping a coverage, ask first whether and on what terms it could be added back. Lowering cost is mostly a matter of improving the inputs, not thinning the program. The broker guide for tree companies has questions that test how many carriers a firm can actually place you with, and the guide to lowering premium without cutting coverage covers the general approach.

Frequently asked questions

Why is insurance so expensive for a tree service company?

Workers' compensation is often a large line, and a trade magazine article by an insurance professional says carriers price tree care accordingly. BLS reports a 2024 fatal injury rate for landscaping services (an industry code that includes tree and lawn companies) of 18.5 deaths per 100,000 full-time equivalent workers, with a margin of error of 1.28, against 3.3 for all workers. Fleet, equipment and liability add to the cost.

Will a lower experience mod reduce my tree company's premium?

Usually it lowers workers' comp premium, because the mod is applied to the premium calculated from payroll and class rates. It takes time, because the mod uses several years of history and the most recent completed year is left out. Correcting errors and managing open claims can help.

Can I lower my tree service insurance by raising deductibles?

Higher deductibles can lower premium, but you then pay more of each claim from cash flow. Model a bad month before choosing, and make sure your lender and contracts do not require a lower deductible.

Do certified arborists and safety programs affect price?

They can. One insurance professional writing for the trade lists company accreditation, certified arborists, written safety programs, documented training and driver screening as items some carriers use for credits. Programs vary by carrier, so ask which ones your carrier recognizes.

When should I start the renewal process?

A trade article recommends sending the submission 90 to 120 days before renewal. Start by gathering loss runs, payroll by class, schedules and safety records, then ask your broker for a timeline. A complete package is less likely to be priced on cautious assumptions.
