Why Your Liability Limits Are a Lie: Umbrella vs. Excess

Your CGL limits aren't enough. Here's why you need a commercial umbrella, not just excess coverage, to actually protect your assets.

Imagine this: you're a contractor, and a client trips over a cable on your job site, breaks their wrist, and sues for $2 million. Your commercial general liability (CGL) policy has a $1 million per-occurrence limit. You assume you're covered. But after the settlement, you're writing a check for the remaining $1 million out of pocket. Sound far-fetched? It's not. The real question isn't whether you have liability insurance—it's whether your limits are built to survive a worst-case claim.

I'm going to answer a very specific question: should you buy a commercial umbrella policy or just crank up your existing liability limits? The answer, as you'll see, is umbrella—and here's why.

The $1 Million Illusion

Most clients and contracts demand at least $1 million in general liability coverage (IRMI). That's the standard. But it's an illusion of safety. The Hartford notes that the average cost of a general liability policy is around $810 a year—that's cheap, but the limit is a ceiling, not a floor. If a claim exceeds that limit, you're on the hook for the difference. And in our lawsuit-happy world, $1 million doesn't go as far as you'd think, especially when legal fees start eating into it.

Here's the kicker: general liability policies are occurrence-based, meaning they cover incidents that happen during the policy period, even if the claim is filed later (The Hartford). That sounds good, but it doesn't help you if a single incident blows past your limit. You need a buffer above that $1 million, and that's where umbrella insurance comes in.

Excess vs. Umbrella: Not the Same

People often use "umbrella" and "excess" interchangeably, but they're not the same. Excess liability extends the limits of one specific policy—say, your CGL. Umbrella insurance, on the other hand, extends the limits of multiple underlying policies, like general liability and commercial auto, giving you broader protection (The Hartford). That's a crucial distinction. If you only buy excess coverage, you're only protecting one bucket. An umbrella covers multiple buckets, so if a gap appears in one, you're still protected.

Let's put some numbers on this. Business umbrella policies have aggregate limits ranging from $1 million to $15 million (The Hartford). That's a lot of headroom. But here's the catch: you can't buy umbrella insurance if you don't have an underlying policy, like a CGL (The Hartford). So the umbrella isn't a replacement—it's an addition. And it's not that expensive, especially compared to the peace of mind it buys.

What Umbrella Actually Covers

Umbrella insurance doesn't just add limits; it can also cover claims that your underlying policies exclude. For example, it can provide coverage for things like personal injury (libel, slander) that might not be in your CGL (The Hartford). But there are limits to the umbrella, too. It won't extend to property claims, like if your commercial property is damaged—that's a separate policy (The Hartford).

Think of it this way: your CGL is the first line of defense, covering bodily injury and property damage. Your professional liability (E&O) covers errors and omissions in your services. But an umbrella sits on top of both, catching the overflow. In fact, The Hartford recommends carrying both general and professional liability for full protection—and I'd argue you need the umbrella on top to make those limits truly work for you.

The Cost of Being Underinsured

So, what happens if you skip the umbrella and just rely on your $1 million CGL? You're gambling. The average cost of a Business Owner's Policy (BOP) is about $1,687 a year (The Hartford). That's not much more than a standalone CGL, and it bundles property and liability. But even that might not be enough if a catastrophic claim hits.

Consider the medical field: premiums have been rising for seven straight years, with 36 states seeing increases in 2025 (Insurance Journal). That's a sign of how liability risk is growing across industries. If you're a contractor or consultant, you're not immune. A single lawsuit could wipe out your business. An umbrella policy, with limits up to $15 million, is a relatively cheap way to cap your exposure.

What I'd Actually Do

Here's my concrete advice: buy a commercial umbrella policy with at least $2 million in limits, on top of your existing CGL and professional liability. Make sure your underlying limits are at least $1 million per occurrence, which is the standard (IRMI). This strategy gives you a $3 million-plus safety net for a fraction of the cost of raising your CGL limits alone.

And don't forget to check your retroactive dates and reporting periods on any claims-made policies—those can be traps (The Hartford). But that's another article. For now, remember: your liability limits are a lie if they're not backed by an umbrella. Don't be the contractor who writes a million-dollar check. Get the umbrella.
