Your CGL Won't Cover a Client's Financial Loss: Why You Need E&O

Imagine you're a consultant. You give a client strategic advice. They follow it. The result? A financial disaster. They sue you for the loss. You pull out your commercial general liability policy, expecting coverage. But your insurer denies the claim. Why? Because your CGL doesn't cover financial harm from professional advice. That's the gap that errors and omissions insurance fills.

Here's the hard truth: general liability and professional liability are fundamentally different. General liability covers bodily injury and property damage. Professional liability covers financial losses from errors and omissions in the services you provide (IRMI). If you only carry CGL, you're leaving your biggest exposure uninsured.

The CGL Illusion

Most business owners think a CGL is enough. It's the standard policy, and clients often require it. The typical limit is $1 million per occurrence with a $2 million aggregate (IRMI). That sounds solid. But CGL only responds to physical risks—like a customer slipping in your office or a product causing property damage. It won't touch a claim that you gave bad advice that cost a client money. That's a professional liability claim, and your CGL will not pay it.

Consider this: a client sues you for negligence after following your flawed recommendation. The damages are purely financial. Your CGL insurer will likely deny coverage because there's no bodily injury or property damage. You're left paying attorney fees and any settlement out of pocket. That's a financial hit that could bankrupt a small business.

E&O: The Coverage You Actually Need

Errors and omissions insurance—also called professional liability—is designed for exactly these situations. It protects against claims of negligence, misrepresentation, inaccurate advice, libel or slander, and copyright infringement (The Hartford). It's not just for lawyers and doctors. Any business that provides professional services should consider it.

E&O coverage is typically written on a claims-made basis. That means you're covered for claims made during the policy period, as long as the incident happened after the retroactive date (The Hartford). The retroactive date is crucial—if you switch insurers, you need to maintain a retroactive date that covers all your past work. Otherwise, you could have a gap in coverage for prior acts.

One key difference: for general liability, defense costs are paid in addition to your policy limit. For professional liability, defense costs are usually included within the limit (IRMI). That means if you have a $1 million limit and legal fees eat up $300,000, you only have $700,000 left to pay a settlement. That's a real trade-off, but it's still better than no coverage at all.

The Cost of Going Bare

Some business owners skip E&O because they think it's expensive. But the average minimum monthly premium for professional liability from The Hartford is $62 for miscellaneous standalone coverage, $239 for architects and engineers, and $146 for technology companies (The Hartford). That's a small price compared to the cost of a single lawsuit. Attorney fees alone can range from $3,000 to $150,000, and settlements can reach millions (The Hartford).

Meanwhile, general liability insurance averages $810 a year (The Hartford). That's cheap because it covers relatively predictable physical risks. Professional liability is riskier to insure, but the cost is still manageable for most businesses.

Don't assume your CGL extends to your professional advice. It doesn't. If you're a consultant, an architect, an IT specialist, or any professional who gives advice, you need E&O. It's that simple.

Quick tip: When you buy E&O, check the retroactive date. Make sure it covers the start of your business operations, or you could have a coverage gap for past work.

The Counterargument: 'I've Never Been Sued'

You might think, 'I've never been sued, so I don't need it.' That's a gamble. The fact is, even doctors get sued. According to a 2024 AMA study, 28.7% of physicians had been sued during their careers, and that number rises to 45.2% for those aged 55 and over (Insurance Journal). If you're in a professional services role, your risk is not zero. And one lawsuit can wipe out years of profits.

Some people argue that a strong contract with a limitation-of-liability clause can protect you. That helps, but it doesn't cover everything. And it won't pay your legal defense if the clause is challenged. E&O insurance is your safety net.

What I'd Actually Do

Here's my recommendation: if you provide any professional advice or service, buy E&O coverage. Don't rely on your CGL. It's not designed for financial harm. Get a policy with a retroactive date that covers your entire business history. The cost is worth it.

If you're on a tight budget, start with a $1 million per claim limit. That's the common starting point (IRMI). You can increase it later as your business grows. But don't go without it. The risk is too high.

And remember: your CGL is for slips and falls. Your E&O is for your expertise. Carry both.
