Live Market Update: Today’s Construction Insurance Trends (November 2025)

Before diving into our carrier rankings, it is crucial to understand the immediate factors influencing your insurance premiums today.

1. The Surge in Medical Inflation and Workers’ Comp Costs

As of late November 2025, a primary driver of rising costs for construction firms is medical inflation. Recent industry reports indicate that the average medical cost per workers’ compensation claim has risen significantly year-over-year. This trend is putting immense pressure on premiums, particularly for high-risk trades where injury probability is statistically higher.

• Actionable Insight: Contractors must leverage telematics and AI-driven safety monitoring to negotiate better rates. Carriers are increasingly offering discounts for firms that can demonstrate proactive risk management.

2. Tightening Capacity in the Excess & Surplus (E&S) Market

Standard carriers are retreating from high-hazard risks, pushing more construction firms into the E&S market. This sector, which handles non-standard risks, is seeing an influx of demand.

• Live Data Point: Capacity for “frame and joisted masonry” construction projects is tightening, with minimum premiums for builders risk policies starting higher than in previous quarters. However, capacity for non-combustible construction remains stable.

3. The Rise of “Nuclear Verdicts” and Liability Limits

Social inflation—the rising costs of insurance claims resulting from increased litigation and larger jury awards—continues to be a trending concern. “Nuclear verdicts” (jury awards exceeding $10 million) are forcing contractors to seek higher umbrella insurance limits, often requiring layered programs involving multiple carriers to reach desired coverage levels of $5M, $10M, or more.

6. Chubb

9. Nationwide (E&S / Scottsdale)

• Best For: Mid-market contractors with harder-to-place exposures.

Deep Dive: Essential High-Risk Coverages for 2025

To truly protect a high-risk construction business, standard policies are insufficient. You must structure a portfolio of coverage that addresses the specific “pain points” of the 2025 legal and physical environment.

Commercial General Liability (CGL) in a Litigious Era

The cornerstone of any construction insurance program, CGL covers third-party bodily injury and property damage. However, for high-risk firms, the details of the policy are critical.

• Action items: Ensure your policy does not have a “Residential Exclusion” or “Subcontractor Warranty” that could void coverage if a sub fails to maintain their own insurance.
• Trending Term: “Action Over Exclusion.” Many cheaper policies include this exclusion, which removes coverage for lawsuits filed by injured employees of subcontractors. Avoid this exclusion at all costs.

Excess and Umbrella Liability: The “Sleep at Night” Coverage

With the average cost of a severe construction accident claim skyrocketing, a $1 million primary limit is rarely enough.

• Market Shift: In 2025, we are seeing contracts frequently require $5 million to $10 million in umbrella limits.
• Strategy: “Towering” limits by using multiple carriers (e.g., $2M from Carrier A, $3M excess of that from Carrier B) can sometimes be more cost-effective than buying a single massive policy.

Builders Risk Insurance: Protecting the Asset

Also known as “Course of Construction” insurance, this covers the structure itself while it is being built.

• High-Risk Focus: For projects in wildfire or hurricane zones, standard carriers may decline. You will likely need a “Difference in Conditions” (DIC) policy or a specific E&S placement to cover these catastrophic perils.
• Cost Driver: Wood frame construction projects are seeing the steepest rate increases due to fire risk.

Workers Compensation for High-Hazard Trades

Roofing, steel erection, and excavation have the highest “Class Codes” rates.

• 2025 Trend: “Ex-Mod” Management. Your Experience Modification Rate (EMR) is the single biggest factor in your premium. An EMR above 1.00 acts as a debit (surcharge).
• Solution: Partner with carriers offering aggressive “Return to Work” programs which help lower claim reserves and reduce your EMR faster.

Inland Marine: Tools & Equipment Coverage

Contractors often mistakenly believe their Business Personal Property (BPP) policy covers their excavators and generators at the job site. It usually does not.

• Requirement: You need an Inland Marine floater to cover equipment that moves from site to site.
• Theft Wave: With equipment theft rising in 2025, ensure your policy covers “Replacement Cost” rather than “Actual Cash Value,” so you aren’t left out of pocket for depreciation on stolen gear.

Understanding Insurance Costs: 2025 Price Breakdown

While every business is unique, current market data gives us a baseline for what high-risk contractors should expect to budget.

Insurance Type	Average Annual Premium (Small-Mid High Risk Firm)	Key Cost Driver
General Liability	$3,000 – $15,000+	Revenue & Operations Type (e.g., Roofing vs. Carpentry)
Workers Comp	$20,000 – $100,000+	Payroll size & Class Codes (Risk level of tasks)
Builders Risk	1% – 4% of Project Value	Construction Type (Frame vs. Concrete) & Location
Commercial Auto	$2,000 – $4,000 per vehicle	Driver Records (MVRs) & Vehicle Weight
Umbrella ($1M)	$1,500 – $3,500	Underlying limits & Claims History

Note: These figures are estimates based on Q3/Q4 2025 market aggregation. High-risk trades in litigious states like New York or California will see significantly higher premiums.

Strategic Risk Management: How to Lower Your CPC (Cost Per Coverage)

Reducing your insurance spend without sacrificing coverage requires a proactive approach. Underwriters in 2025 are looking for “best-in-class” operations.

1. Subcontractor Management Protocols

Liability often flows upstream. If your subcontractor causes an accident and has no insurance, you are liable.

• Best Practice: Implement an automated Certificate of Insurance (COI) tracking system.
• Requirement: Mandate that all subcontractors name your firm as an “Additional Insured” on a primary and non-contributory basis.

2. Technology Integration

Carriers like AXA XL and Travelers are offering premium credits for tech adoption.

• Wearables: Devices that track employee lifting techniques to prevent back injuries.
• IoT Sensors: Water leak detectors in high-rise construction to prevent massive water damage claims during the build.

3. Contractual Risk Transfer

Your client contracts are your first line of defense. Ensure your “Indemnification” clauses are reviewed by a construction attorney to ensure they are enforceable in your state. Passing liability to the responsible party is the most effective way to protect your loss history.

---

The Role of Specialized Brokers vs. Direct Writers

For high-risk construction, the “Direct to Consumer” (online quote) model often fails.

• The Broker Advantage: You need a “Retail Broker” who has access to “Wholesale Brokers” (like Amwins, CRC, or RT Specialty). These wholesalers are the gatekeepers to the E&S markets (AIG, Scottsdale, etc.).
• Selection Criteria: Ask your broker, “How much construction premium do you place annually?” If they are a generalist, they likely lack the leverage to negotiate with the tough high-risk underwriters.

---

Conclusion: Securing Your Future in a Hard Market

The landscape for high-risk business insurance in 2025 is defined by selectivity. Carriers are willing to deploy capital, but only for contractors who treat risk management as a core business function.

By aligning with top-tier carriers like Chubb, Travelers, or AXA XL, and utilizing the specialized capacity of the Excess & Surplus market, construction firms can build a shield against the financial threats of modern litigation and physical perils.

Do not wait for your renewal date. Start the conversation with your broker 90 to 120 days in advance. The complexity of the 2025 market demands time to market your account to multiple carriers to secure the most competitive liability insurance quotes.
