Your CGL Won't Save You: Why Every Professional Needs E&O

General liability covers slips and falls, not your mistakes. Here's why most businesses need both—and how to avoid the coverage gap that could bankrupt you.

The Hard Truth About Your Coverage

Less than a third of physicians (28.7%) had been sued during their careers in 2024, according to the AMA—and for older doctors, that number jumps to 45.2% (Insurance Journal). If medical professionals face that kind of exposure, what makes you think your business is safe? The reality is, if you provide any kind of service or advice, you're a target. And if you're relying solely on a general liability policy, you're playing Russian roulette with your livelihood.

The Gap: Physical vs. Financial Harm

General liability insurance—the CGL—is the workhorse of business coverage. It pays for third-party bodily injury and property damage, and it's cheap: The Hartford averages about $810 a year. But here's the catch: it doesn't cover the kind of harm your clients are most likely to sue you for—financial losses from your mistakes, missteps, or bad advice. That's the domain of professional liability, also known as errors and omissions (E&O).

Think about it. A client hires you to file their taxes, design their website, or manage their construction project. If you miss a deadline and they lose a contract, that's a financial loss. A CGL won't touch it. Only E&O covers claims of negligence, misrepresentation, and inaccurate advice (The Hartford).

Two Different Worlds: Occurrence vs. Claims-Made

The differences go deeper than just what's covered. CGL is 'occurrence-based': if an injury happens during your policy period, you're covered even if the claim comes years later. Professional liability is typically 'claims-made': you're only covered if the claim is filed while the policy is active—and even then, only if the incident happened after the policy's retroactive date (IRMI). That's a trap for the unwary. If you let your E&O lapse and a client sues you six months later for something you did last year, you're on your own.

Defense Costs: The Hidden Budget Buster

Here's another kicker: defense costs. With a CGL, defense is paid in addition to your policy limit. With professional liability, defense costs are typically included within the limit (IRMI). That means a $1 million E&O policy might only leave you $700,000 for a settlement after legal fees. And legal fees are no joke—E&O defense costs can run from $3,000 to $150,000 (The Hartford). Make sure you understand how your policy handles defense, or you could be blindsided.

The Umbrella Illusion

You might think a commercial umbrella policy has your back. But umbrellas only extend the limits of your underlying policies—they don't create new coverage. If you don't have E&O, your umbrella won't cover a professional mistake. It's like buying a bigger shield when you don't have a sword. (The Hartford)

What I'd Actually Do

Here's my blunt advice: if you provide any service for a fee—consulting, design, tech, healthcare, law—buy professional liability insurance. Period. The cost is manageable: The Hartford's average monthly minimums range from $38 for healthcare professionals to $239 for architects and engineers. That's a fraction of what one lawsuit could cost you. And don't stop there. Get a CGL too, because E&O won't cover a slip-and-fall in your office. Carry both, and make sure you understand the claims-made nature of your E&O—know your retroactive date and consider an extended reporting period if you switch carriers.

Quick tip: When you buy E&O, ask for a 'retroactive date' that covers your past work. If you change insurers, negotiate an extended reporting period—it's worth the extra cost.
