General Liability vs Professional Liability Insurance: Which Do You Need?
One covers physical harm caused by your operations. The other covers financial harm caused by your professional advice or services. Most service businesses need both. The two almost never overlap; if a claim falls under one, it does not fall under the other.
Side-by-side comparison
| Attribute | General liability | Professional liability (E&O) |
|---|---|---|
| What it covers | Bodily injury, property damage, advertising injury | Financial harm from professional advice or services |
| Trigger | An incident at your premises or operations | An act, error, or omission in your professional work |
| Policy form | Occurrence (covers incidents during the policy period) | Claims-made (covers claims filed during the policy period) |
| Common claim | Customer slip and fall | Client says your advice cost them money |
| Who needs it | Almost every business with physical operations | Service businesses giving advice or expertise |
| Typical limit | $1M / $2M | $1M / $1M to $2M / $2M |
| Tail / extended reporting | Not generally needed | Often required when you switch carriers or retire |
Cost comparison by business type
Combined GL + E&O cost for ten common service-business types. Ranges assume a one- to three-person firm under $500K revenue, $1M / $2M GL limits, and $1M / $1M E&O limits. Bundling typically nets a 10 to 15 percent discount versus the standalone-only sum below.
| Business type | GL only / yr | E&O only / yr | Combined annual |
|---|---|---|---|
| Management consultant | $400 - $700 | $500 - $1,200 | $900 - $1,800 |
| IT consultant | $500 - $900 | $800 - $1,800 | $1,300 - $2,500 |
| Marketing consultant | $400 - $800 | $600 - $1,400 | $1,000 - $2,000 |
| HR consultant | $400 - $700 | $700 - $1,500 | $1,000 - $2,000 |
| Bookkeeper / accountant (small) | $400 - $700 | $500 - $1,000 | $900 - $1,600 |
| Real estate agent | $400 - $700 | $500 - $1,200 | $900 - $1,800 |

Who needs which
GL primarily
Businesses where the dominant exposure is physical: contractors, restaurants, retailers, fitness studios, salons, landscapers. GL is the larger purchase. E&O is rarely required unless the client contract specifies it.
E&O primarily
Businesses where the dominant exposure is the quality of professional advice or services: consultants, attorneys, accountants, real estate agents, financial advisors, IT services. E&O is the larger purchase. GL is often required by lease or contract but is the smaller line item.
Both, in roughly equal measure
Architects, engineers, designers, and IT services that include hardware deployment all face significant exposure in both directions. Architects can have a client trip in their office (GL) and a structural recommendation cause a building failure (E&O); IT services can drop a server (GL) and misconfigure a system (E&O). Both policies carry similar premium weight.
Real scenarios
| Scenario | Which policy | Why |
|---|---|---|
| Client trips during a meeting at your office | GL | Bodily injury, premises |
| Your strategy advice loses the client a major contract | E&O | Financial harm from professional advice |
| Your IT consultant deletes a database during a migration | E&O | Professional act causing financial harm |
| Your marketing copy infringes a competitor's trademark | GL (advertising injury) | Personal & advertising injury |
| You drop a laptop on a client's foot during an installation | GL | Bodily injury caused by your operations |
| You give tax advice that triggers an IRS penalty | E&O | Professional act causing financial harm |
