$10M Professional Liability (E&O) Insurance for Third-Party Inspection Firms

A contract that asks a third-party inspection firm for $10M is usually met with a primary Professional Liability policy plus excess layers.

What does a $10M requirement mean for third-party inspection firms?

Professional Liability (E&O, short for Errors and Omissions) covers claims that your inspection, test or report caused a client a financial loss. Your risk sits in what you accept or release. One example is a supplier's compressor after vendor surveillance (checking a supplier's work before it ships). A $10M clause might read like this:

• Each claim and aggregate: the most paid on one claim, and on all claims in one policy year.
• Claims-made: the policy covers claims made while it is active, for work done after the retroactive date (the earliest work date it covers).
• Six years after acceptance: missed defects can surface late, so the coverage must run that long.
• Primary plus excess: this clause allows a stack. If yours is silent, confirm with the client that primary plus follow-form excess meets it.

Who asks third-party inspection firms for $10M?

Contracts for these firms often ask for $2M or less, and larger accounts may ask for $5M. $10M tends to come from owners of very large assets, where one wrongly accepted item could halt a plant. Typical sources:

• LNG, offshore and refinery operators that may buy surveillance of compressors, turbines and pressure vessels.
• Engineering, procurement and construction (EPC) contractors passing high limits down to vendors, and public programs where bid documents set the limit.

How is $10M built?

Many inspection firms buy Miscellaneous Professional Liability, a general form for service firms that have no form of their own. If licensed engineers stamp your reports, the firm often buys Architects and Engineers (A&E) Professional Liability instead. A primary policy pays first. Each excess layer pays only after the layers below it are used up.

Each excess layer should follow form, meaning it adopts the primary policy's terms. Keep the same retroactive date and policy period on every layer.

Many Professional Liability policies pay defense costs inside the limit, so legal fees can use up part of it. A commercial umbrella almost never counts toward it.

What will underwriters ask for?

Underwriters (the people who review and price the risk) on each layer may ask for:

• Revenue by service: vendor surveillance, expediting (tracking a supplier's order status and delivery), NDT (nondestructive testing), and coating or welding inspection.
• The $10M contract, the equipment involved, its value and the cost of delay.
• Whether you release items, witness tests or only report findings, and who reviews reports.
• How you supervise contract inspectors, especially at overseas shops.
• Your client terms, including indemnity (a promise to cover the client's losses) and any limitation of liability clause (a cap on what you owe).
• Five years of loss runs (a report listing past claims), any known incidents, and your current policy with its retroactive date.

What affects the cost?

• What you sign off on. Pressure equipment, rotating machinery and offshore work usually cost more to insure.
• How the tower is built. The primary layer often costs the most per $1M, and higher layers often cost less, but this varies.
• Claims history. Past claims can raise the price.
• Retention and defense terms. Retention works like a deductible. A higher one usually lowers premium. Defense outside the limit may cost more.

Frequently asked questions

Do I need $10M Professional Liability as a third-party inspection firm?

Only if your contract or bid documents say so. $10M usually comes from one very large owner, program or public contract. In a made-up example, your inspector releases a large compressor after a factory test. It fails at startup, and the operator blames your acceptance for months of lost output.

I have $2M Professional Liability today. How do I get $10M as an inspection firm?

Request new quotes through Morrow for excess layers or a new, higher primary, keeping your retroactive date and prior acts coverage (cover for work done before the new policy starts) where the market allows. Report known incidents to your current insurer before you switch.

Can the client be added as an additional insured on my Professional Liability?

Usually not. Some carriers may name a client for liability arising from your services, and each excess layer would have to match. Many clients accept a certificate of insurance (a one-page proof of coverage) listing each layer.

How long does it take to get $10M Professional Liability for an inspection firm?

It often takes longer than a single policy, because each layer is underwritten separately and may ask for the contract, loss runs and your inspection process. Timing varies, so starting early usually helps.
