Contractors E&O Insurance for professional contractors
Insurance covering claims that your professional services — designs, specifications, project management, or advice — caused a client financial harm. Standard GL policies exclude this entirely. E&O is the coverage professional contractors cannot operate without.

What it covers
- Design errors and omissions in drawings and specifications
- Project management failures and missed milestones
- Cost estimate errors that lead to overruns
- Specification mistakes that require rework or remediation
- Professional advice and consulting errors
- Defense costs and legal fees when a client files suit
Who it's for
- Design-build contractors providing both design and construction
- Project managers and construction managers-at-risk
- Specialty contractors providing design-assist or engineering services
- Any contractor whose services include professional judgment or advice
Why CCA
- We value your E&O exposure based on actual services — not a generic contractor form
- Combined GL + E&O programs available so there's no gap between the professional and trade sides
- E&S market access for contractors with prior professional liability claims
Common questions about contractors e&o insurance
No. Standard GL policies contain a professional services exclusion that removes coverage for errors in design, specifications, project management, and professional advice. E&O (professional liability) is the separate policy that covers those claims.
A client alleging that your professional services caused financial harm — a design error requiring rework, a missed specification that caused cost overruns, a project management failure that delayed completion, or professional advice that led to a bad outcome.
It depends on your largest single contract and total professional services revenue. Many professional contractors carry $1M per claim / $2M aggregate as a starting point; large design-build firms may need $5M or more. We model your realistic worst-case and size the limit.
When you're the responsible party and a subcontractor's error leads to a professional liability claim against your firm, your E&O policy covers your exposure as the directing or coordinating contractor — including defense costs.
Contractor professional liability is almost always written on a claims-made basis — meaning the policy in force when the claim is filed responds, not the policy in force when the work was done. Tail (extended reporting period) coverage is important when changing carriers.
For most contractors with ongoing work, an annual policy covering all projects is most efficient. For a single large project with unique risk, a project-specific policy with dedicated limits may be better. We help you evaluate both.
The retroactive date is the earliest project start date covered by your claims-made policy. A full prior-acts policy (retroactive to inception) covers all your past work; a limited retroactive date leaves earlier work exposed. We negotiate full prior acts wherever possible.
Cost is driven by services performed, annual revenue, contract types, and professional liability claims history. We quote your actual firm in about 15 minutes — never a ballpark from a generic business form.
Yes. Contractors Choice Agency is licensed in all 50 states and writes professional contractor programs nationwide — Arizona, Texas, California, the Northeast, Pacific Northwest, and everywhere contractors operate.
Typically 15 minutes on a call. Larger or more complex programs may take a day or two to place with the right markets, but we move fast and set expectations up front.
Often yes. We have admitted and E&S markets for professional contractors declined over prior claims, loss runs, or complex project types. Bring us your situation and we'll find a market.
Usually yes. A coordinated program closes gaps between policies and is typically cheaper than separate policies from separate carriers — and far easier to manage at claim time.
A.M. Best ratings reflect a carrier's financial strength and ability to pay claims. We place coverage with A-rated (and A+ where possible) carriers so the coverage is there when a professional liability claim, contract dispute, or construction defect suit hits.
Yes. Design-build firms carry both professional and trade liability; project managers carry significant professional services exposure; specialty contractors have unique E&O profiles. We tailor each program to the specific services your firm provides.
Claims are evaluated based on the alleged harm — cost overruns tied to professional errors, project delays, design defect remediation costs, and client financial losses. We work with carriers that handle contractor professional liability claims efficiently and fairly.
Services performed, annual revenue, contract types (fixed-price, cost-plus, design-build), largest single project, professional liability history, current coverage, and loss history. More detail means a more accurate quote.
If you're the responsible contractor and a subcontractor's error leads to a professional liability claim against you, your policy covers your exposure as the directing or coordinating party — including defense costs and resulting liability.
Yes. Project-based contractors can obtain project-specific professional liability policies for individual large contracts, while ongoing firms carry annual programs. We match the program structure to how your firm actually operates.
That's a professional liability (E&O) claim. Your policy covers your defense costs, legal fees, and any resulting judgment or settlement — up to your policy limits. Without E&O coverage, you'd pay out of pocket.
Yes. If you operate through multiple entities, joint ventures, or have separate design and construction arms, we build one coordinated program covering all entities with no gaps between them.
