Somewhere between 20% and 42% of small businesses carry Errors & Omissions (E&O) coverage. If you run a contracting business in Missouri or Arkansas and you’re not sure whether E&O belongs in your insurance program, here’s what you need to know.
What is Errors & Omissions insurance?
Errors & Omissions insurance — sometimes called professional liability insurance — protects your business when a client claims your work, advice, or design caused them a financial loss. That could be a design flaw, a miscalculation, a missed specification, or a mistake in professional judgment that costs your client money, even if no one was physically hurt and no property was damaged.
Doesn’t my General Liability policy already cover this?
No — and this is the gap that catches contractors off guard. General Liability policies generally exclude faulty workmanship and purely financial losses. GL responds when your work causes bodily injury or property damage to a third party. It does not respond when a client says your design was wrong, your installation didn’t meet spec, or your professional recommendation cost them money.
Consider an HVAC contractor who designs and installs a system that turns out to be undersized for the building. Nothing is broken and no one is injured — but the client faces higher energy costs, comfort complaints, and the expense of correcting the system. That’s a professional liability claim, and a standard GL policy is not built to pay it.
Which contractors need E&O coverage most?
E&O is most critical for contractors whose work involves design decisions, engineering judgment, or technical specifications:
- Design-build contractors who take on both design and construction responsibility
- Electricians, whose work involves load calculations, code compliance, and system design
- HVAC contractors handling system sizing, design, and efficiency specifications
- Any contractor providing consulting, plans, or professional recommendations alongside the physical work
Many general contractors also pick up design exposure without realizing it — any time you modify a plan, substitute a material, or advise a client on an approach, you’re making a professional judgment that E&O is designed to cover.
A warning for independent contractors
Independent contractors need to read their policies carefully. Many standard E&O policies explicitly exclude independent contractors, which means a solo operator or subcontractor may believe they’re covered when they’re not. If you work independently, you’ll likely need a specialized contractor E&O policy written for your situation rather than relying on a generic professional liability form — or on the general contractor’s policy above you.
Is E&O required in Missouri and Arkansas?
Requirements vary by trade, licensing board, and — most often — by contract. Even when state law doesn’t mandate E&O for your trade, many commercial clients, municipalities, and general contractors require proof of professional liability coverage before you can bid or sign. If E&O keeps showing up in the contracts you’re asked to sign, that’s your answer.
How much E&O coverage does a contractor need?
There’s no one-size-fits-all limit. The right amount depends on your project sizes, the contracts you sign, your trade’s exposure, and what your clients require. A contractor doing $50,000 residential jobs has a very different exposure than one designing systems for commercial buildings. An independent agent can benchmark your limits against your actual contract requirements and project values.
The bottom line
If your work involves design, engineering, or technical judgment — or if your contracts require it — E&O isn’t optional protection, it’s a core part of your insurance program. And if you’re an independent contractor, don’t assume a standard policy covers you until you’ve confirmed it in writing.
