Professional Liability Insurance for Engineers
Protect your engineering firm against claims involving errors, omissions, negligence, and professional services.


Coverage for the Finer Details
Professional Liability Insurance for Engineers, often called errors and omissions or E&O insurance, is designed for claims connected to professional services. For an engineering firm, those services can include designs, calculations, reports, specifications, consulting, and other professional work.
A client may allege that an error, omission, or failure to meet the expected professional standard caused financial loss or another form of damage. Professional liability insurance can help respond to covered claims and defense costs, subject to the terms of the policy.


Professional Work Creates Liability
Designs, calculations, specifications, reports, and consulting can lead to claims when a client alleges a professional error.
Defense Costs Can Add Up
Even a disputed claim can require attorneys, experts, documentation, and significant time from the firm.
Clients May Require It
Project contracts often specify professional liability limits or other insurance requirements before work begins.
Your Exposure Changes as You Grow
Larger projects, new disciplines, higher revenue, and different clients can change the professional risk your firm carries.


How to Evaluate Your Coverage
The right solution should reflect the firm’s actual services, agreements, people, projects, and growth plans.


Frequently Asked Questions

Is professional liability insurance the same as E&O insurance?
For engineering firms, the terms are commonly used to describe coverage for claims involving professional errors, omissions, or negligence. The exact policy language and coverage still depend on the carrier.
Does general liability insurance cover engineering errors?
General liability is generally designed for risks such as third-party bodily injury or property damage outside your professional services. Professional liability is the coverage specifically designed around allegations involving professional work.
Do engineering firms have to carry professional liability insurance?
Requirements depend on the firm, jurisdiction, client, and contract. Even when it is not legally required, a client or project agreement may require professional liability coverage.
How much professional liability insurance does an engineering firm need?
There is no single limit that fits every firm. Project size, contract requirements, discipline, revenue, prior work, client type, and the firm's ability to absorb a loss should all be considered.
Does professional liability insurance cover work completed in previous years?
It can, depending on the policy's prior-acts terms, retroactive date, reporting requirements, and continuous coverage history. These details should be reviewed before changing carriers or policies.
