For third-party inspection firms: a $3M Professional Liability (E&O) clause usually means $3M per claim and per year, met by one primary policy or by a primary policy plus follow-form excess.
The short answer
- A $3M requirement means your inspection firm needs Professional Liability (E&O) of $3M per claim and per year, usually from one $3M primary policy or a $1M or $2M primary policy plus a follow-form excess layer.
- $3M is high for inspection work and often comes from energy, heavy industrial and large public projects. Confirm with the client that primary plus excess meets the clause.
- $3M for inspection work is rarely available online and is usually placed by a broker. Morrow can help you find it.
What does a $3M requirement mean for third-party inspection firms?
Professional Liability (E&O, short for Errors and Omissions) covers claims that your services caused a client financial loss. For an inspection firm, the claim usually centers on a report or a release that let faulty equipment ship. A $3M clause in a master service agreement (the main contract for your work) might read like this:
Illustrative contract wording
Inspection Contractor shall maintain Professional Liability insurance covering source inspection, vendor surveillance and reporting services, with limits of not less than $3,000,000 per claim and $3,000,000 annual aggregate. Limits may be met by primary and follow-form excess policies. If written on a claims-made basis, coverage shall be maintained for three (3) years after completion of the Services.
Illustrative example only. Your contract's wording controls.
- Per claim and aggregate: the most paid on one claim, and on all claims in a policy year. Here, $3M each.
- Stacking allowed: the second sentence lets you combine policies.
- Claims-made: the policy covers claims first made while it is active, for work on or after the retroactive date (the earliest work date covered).
- After the job: the clause may require coverage for three years after the work ends, so claims-made coverage usually has to stay in force that long, on every layer.
Who asks third-party inspection firms for $3M?
Moving from $2M to $3M often means a higher primary or an added excess layer, so quote both. $3M comes up when one bad report could cost the client far more than your fee:
- Refinery, chemical and power plant owners buying source inspection of pressure vessels (tanks built to hold gas or liquid under pressure) and valves at a supplier's shop.
- Pipeline and utility operators hiring weld, coating and nondestructive testing (NDT, checking parts without damaging them) crews.
- Owners of large buildings who set one limit for every special inspection firm.
- Government agencies, where the limit is set in the bid.
Many firms buy Miscellaneous Professional Liability (a form for services that fit no named profession), often alongside General Liability (coverage for injury or property damage to others). Firms whose reports carry an engineer's stamp usually need Architects and Engineers (A&E) Professional Liability instead.
How is $3M built?
A primary policy pays first. An excess layer pays only after the primary limit is used up. "$1M xs $2M" means $1M above the first $2M.
Option 1: one policy
Option 2: $2M primary plus excess
Option 3: $1M primary plus excess
The excess should follow form, meaning it follows the primary policy's terms and retroactive date. A commercial umbrella almost never covers Professional Liability, so it usually cannot be used to meet this requirement. If you carry $1M or $2M today, request new quotes through Morrow for a $3M primary policy or excess layers, keeping your retroactive date and prior acts coverage (coverage for work you did before the new policy started) where the market allows.
Good to know
Defense costs can shrink the $3M. Many policies pay defense costs inside the limit. A dispute over a failed pressure vessel can drain much of the limit. See defense costs inside or outside the limit.
What will underwriters ask for?
Underwriters are the carrier's risk reviewers.
- Your services by share of revenue: source inspection, NDT, welding, coatings or special inspections.
- Whether you sign releases or certificates of conformance, or only report.
- How you follow the client's inspection and test plan (ITP, the list of required checks).
- Inspector certifications, and how many inspectors are contractors or work at overseas shops.
- The contract requiring $3M, its indemnity section (who pays if something goes wrong) and your largest contracts.
- Loss runs (your carrier's report of past claims) for three to five years, and your current policy.
What affects the cost?
- What you inspect. Pressure equipment and energy sites usually cost more to insure than consumer goods.
- Sign-off authority. Firms that release equipment usually carry more risk than firms that only report.
- Structure. A single policy and a primary plus excess setup are priced differently, and which is cheaper varies by market and account, so it helps to quote both.
- Claims history. Past claims can raise the price or limit the primary a carrier offers.
Frequently asked questions
What could a $3M claim look like for a third-party inspection firm?
One missed defect on a signed release can lead to costs past a smaller limit. In this made-up example, your inspector signs the release on a heat exchanger. After installation, a leak forces the refinery unit offline. The owner claims repair and delay costs.
Can my client be added as an additional insured on $3M Professional Liability?
Not automatically, and often not at all. Some carriers will add a client for liability from your services, but many will not. A certificate of insurance (one-page proof of coverage) only shows that coverage exists. It does not add the client. In a primary plus excess setup, the excess must also follow form to extend this status.
Is $3M enough if a later inspection contract asks for $5M?
No, a $5M clause needs $5M of limits. $5M is very rare online and almost always requires a broker. Morrow can help you find it. See $5M for inspection firms.
