Best Commercial Insurance Carriers for Contractors (2026)

Contractors are the bread and butter of commercial insurance agencies, but carrier selection makes or breaks the account. The wrong carrier means declinations, slow quotes, or pricing that loses the bid. The right carrier means auto-issued policies, competitive rates, and a client who stays on the books for years.

This guide ranks the best commercial insurance carriers for contractors — from standard market workhorses like Hartford and Travelers to specialty programs that handle the trades nobody else will touch. If you are looking for coverage details by trade, start with our contractor insurance guide. This article is about which carriers to send those submissions to.

TLDR: Hartford and Travelers handle the majority of standard contractor risks with strong auto-issue platforms. For high-hazard trades like roofing, structural steel, and demolition, you need specialty markets — BTIS, Builders Mutual, or program administrators. Workers comp is the most carrier-sensitive line: EMR, class code, and state jurisdiction all determine which carriers will even look at the risk.

What Makes a Good Contractor Carrier

Not every carrier that writes commercial insurance is a good fit for contractors. The ones that perform well in this niche share a few traits:

• Broad class code appetite. A carrier that writes painters but declines electricians creates gaps in your book.
• Competitive workers comp pricing. WC is the largest premium line for most contractors, and rates vary dramatically by carrier and state.
• Auto-issue or fast-turnaround quoting. Contractors need certificates yesterday. A carrier that takes two weeks to underwrite a GL submission loses to one that binds same-day.
• Subcontractor endorsement flexibility. GCs need additional insured endorsements, waiver of subrogation, and primary/non-contributory language on demand.
• Multi-line packaging. The ability to bundle GL, commercial auto, inland marine, and umbrella on a single account reduces admin and improves retention.

Carrier Comparison Table

Top Carriers in Detail

Hartford

Hartford is the default first-look carrier for most independent agents writing contractor business. Their Spectrum platform auto-issues BOP, GL, and WC for a wide range of artisan trades — electrical, plumbing, HVAC, painting, carpentry, and general contracting up to moderate revenue thresholds.

Strengths:

• Broadest artisan trade appetite in the standard market. Roughly 75% of small commercial quotes auto-issue without underwriter involvement through the Spectrum platform.
• Competitive workers comp pricing in most states, particularly for accounts with an EMR at or below 1.0.
• Strong package capabilities — GL, WC, commercial auto, inland marine, and umbrella can sit on a single account with one renewal date.
• Inland marine program covers tools and equipment up to $500K without a separate application.

Limitations:

• Declines roofing above two stories, structural steel, demolition, and most excavation contractors.
• Revenue caps on auto-issue are lower than Travelers for GC accounts.
• Loss history tolerance is tight — two or more GL claims in three years typically requires underwriter review.

Travelers

Travelers competes directly with Hartford but tends to win on mid-market and larger contractor accounts. Their underwriting appetite extends further up the revenue scale, and their package pricing for GCs managing multiple subcontractor relationships is often sharper than Hartford's.

Strengths:

• Stronger appetite for GCs in the $1M–$10M revenue range. Where Hartford caps auto-issue, Travelers often still quotes through their portal.
• Excellent umbrella capacity — up to $25M through their Excess Casualty unit, with $5M commonly available on standard contractor accounts.
• For-Hire auto appetite is broader than most standard markets, which matters for contractors running fleets.
• Superior subcontractor management endorsements, including blanket additional insured and automatic waiver of subrogation.

Limitations:

• Portal experience is less streamlined than Hartford's Spectrum for small artisan accounts.
• Workers comp pricing in high-hazard class codes is conservative — they prefer clean accounts.
• Similar trade exclusions to Hartford on roofing, steel erection, and demolition.

BTIS (Builders & Tradesmen's Insurance Services)

When Hartford and Travelers decline the risk, BTIS is usually the next call. Part of the Amynta Group, BTIS is a managing general agent that partners with over 30 A+-rated carriers to place contractor classes that standard markets avoid — roofing, structural steel, concrete, demolition, and environmental remediation.

Strengths:

• Writes roofing contractors (including steep slope and commercial) that every standard market declines.
• GL-only placement available, which is critical when you need to split GL and WC across different carriers.
• Broad geographic appetite — writes in all 50 states with no territorial restrictions on most classes.
• Fast turnaround: most quotes return in 48 hours with minimal supplemental information required.

Limitations:

• Limited workers comp availability — BTIS offers WC through Berkshire Hathaway GUARD on its marketplace, but it is not their core product and availability varies by class and state.
• Pricing reflects the specialty risk: expect 30–50% higher GL rates than standard market equivalents.
• Non-admitted in most states, which means surplus lines taxes and fees apply.
• No auto-issue — every submission goes through an underwriter.

Employers Holdings (Employers)

Employers is a workers comp specialist focused on small businesses in low-to-medium hazard industries, and for contractor accounts where WC is the dominant premium line, they are worth quoting. Their appetite covers many artisan trades, though they are most competitive on lower-hazard classifications rather than heavy construction.

Strengths:

• Broad workers comp appetite across low-to-medium hazard class codes, including many artisan trades where Hartford and Travelers may price aggressively.
• Strong in states with competitive WC markets (California, Texas, Florida, Illinois).
• EMR flexibility — generally more tolerant of elevated EMRs than standard carriers, often quoting accounts that Hartford and Travelers decline.
• Payroll audit process is straightforward, which matters for contractors whose payroll fluctuates seasonally.

Limitations:

• GL offerings are limited and generally not competitive with Hartford or Travelers.
• No package discount since WC is their primary product.
• Declines the same high-hazard trades (roofing, demo) as standard markets on WC.

Acuity

Acuity is a regional carrier headquartered in Wisconsin that punches above its weight in the contractor space across the Midwest and expanding territories. For agents in their footprint, Acuity often delivers the best combination of pricing and appetite for artisan trades.

Strengths:

• Aggressive pricing on contractor GL and WC in their core Midwest territory — often 10–15% below Hartford on comparable risks.
• Writes a broader range of artisan trades than their size suggests, including some moderate-hazard classes.
• Package capabilities rival the nationals — GL, WC, auto, inland marine, and umbrella on a single policy.
• Strong claims handling reputation, which supports retention.

Limitations:

• Geographic appetite is limited. If you are outside their operating states, Acuity is not an option.
• Revenue thresholds for auto-issue are lower than national carriers.
• High-hazard trade exclusions are consistent with other standard markets.

Builders Mutual

Builders Mutual is a Mid-Atlantic and Southeast-focused carrier built specifically for the construction industry. Unlike generalist carriers that happen to write contractors, Builders Mutual's entire book is construction — which means their underwriters understand the nuances of trade classification and project-type risk.

Strengths:

• Writes trades that standard carriers avoid, including some roofing and concrete classifications.
• Construction-specific endorsements are standard rather than add-on — sub guard, tools coverage, and project-specific additional insured.
• Underwriters have construction industry backgrounds, which speeds the submission process for complex risks.
• Competitive WC pricing in the Southeast, where they have the deepest loss data.

Limitations:

• Mid-Atlantic and Southeast territory only — primarily operates in NC, SC, VA, GA, FL, TN, MS, MD, and DC.
• Not competitive outside their core geography.
• Smaller carrier, so umbrella capacity tops out lower than Hartford or Travelers.

Matching Carriers to Trade Type

The table below maps common contractor trades to the carriers most likely to quote competitively. "Primary" means the carrier is a first-look option; "Secondary" means they will quote but may not be the most competitive; "Specialty" means you are in surplus lines or program territory.

A few patterns stand out:

• Light trades (painting, flooring, landscaping) have the most carrier options. Nearly every standard market writes them, so the competition is on price and package structure.
• Moderate trades (electrical, plumbing, HVAC, masonry) require carriers with construction underwriting expertise. Hartford and Travelers handle most of these, but Acuity and Builders Mutual can undercut them in their territories.
• High-hazard trades (roofing, structural steel, demolition, excavation) live in specialty markets. If the account involves working at heights above three stories or demolition of any kind, plan on BTIS, Builders Mutual, or a program administrator from the start.

Workers Comp Deserves Its Own Strategy

Workers comp is the line where carrier selection matters most for contractors. Unlike GL — where appetite is relatively consistent across standard carriers — WC pricing varies by 30% or more between carriers on identical risks. The variables that drive this spread:

• State jurisdiction. Monopolistic states (Ohio, Washington, Wyoming, North Dakota) have only one option. In competitive states, carrier selection is the primary lever.
• Experience modification rate. An EMR above 1.0 eliminates some carriers entirely. Above 1.2–1.3, you are likely in assigned risk or specialty territory — and many GCs will not hire subcontractors above those thresholds.
• Class code mix. A contractor with payroll split across multiple class codes needs a carrier that prices each code competitively, not just the primary one.
• Payroll volume. Small-premium WC accounts (under $5,000 annual) have fewer carrier options. biBERK and AmTrust are often the only standard markets willing to write minimum-premium contractor WC.

When to Use Multiple Carriers

Packaging everything with one carrier is simpler, but it is not always the best strategy for contractor accounts. Splitting lines across carriers makes sense when:

• WC pricing from your package carrier is not competitive. Move WC to Employers or a state fund and keep GL, auto, and inland marine with Hartford or Travelers.
• The account includes a high-hazard trade. A GC who self-performs roofing might need GL from BTIS and WC from a state fund, with auto and umbrella from a standard carrier.
• Umbrella capacity requires stacking. Large GC accounts sometimes need $10M+ umbrella limits. Stack a $5M Travelers umbrella with a $5M excess from a London market.

The trade-off is administration. More carriers means more renewals, more audits, and more certificate requests going to different places. Make sure the pricing advantage justifies the operational cost.

Frequently Asked Questions

Which carrier is best for a new contractor with no loss history?

Hartford is typically the best starting point. Their Spectrum platform auto-issues GL and WC for new ventures in most artisan trade classifications, and they do not penalize new businesses as aggressively as some carriers. Travelers is a close second but may require underwriter review for brand-new entities. For very small contractors (under $500K revenue), biBERK offers fast online binding with minimal underwriting friction.

Can I write a roofing contractor through a standard market?

Generally, no. Hartford, Travelers, CNA, and most standard carriers exclude roofing contractors — particularly commercial roofing and steep-slope residential work. BTIS and Builders Mutual are your primary options. Some regional carriers will write residential re-roofing with height restrictions (two stories or less), but confirm the specific exclusions before binding.

How do I handle a contractor with a high EMR?

Start with the state workers comp assigned risk pool, which is required to accept any employer. Then check Employers Holdings and AmTrust, both of which have broader EMR tolerance than standard carriers. Above 1.3–1.5, you are almost certainly in assigned risk territory. On the GL side, a high EMR usually does not affect placement — GL carriers care about GL losses, not WC experience.

Should I always package GL and WC with the same carrier?

Not necessarily. Packaging is convenient and sometimes earns a multi-line discount, but WC pricing varies enough between carriers that splitting can save the client 15–20% on their largest premium line. Run both scenarios — packaged and split — and let the numbers decide. The administrative overhead of two carriers is manageable if the savings are meaningful.
