General Liability vs Professional Liability Insurance: Which One Your Business Needs, or Both

General liability and professional liability cover different kinds of claims. General liability addresses third-party bodily injury, property damage and personal or advertising injury (opens in a new tab) tied to business operations. Professional liability, also called errors and omissions (E&O) insurance, addresses claims that your advice or services contained an error, omission, negligence, misrepresentation or failure to perform that cost a client money (opens in a new tab). A business can need one or both, and the answer turns on the work you do, your physical operations, your contracts, any licensing rules and the wording of each policy. A business owners policy (BOP) can include general liability, and professional liability is usually a separate policy or a specific endorsement (opens in a new tab).

Do you need general liability, professional liability, or both?

Start with the kind of harm a client or stranger could claim. If someone could be hurt or their property damaged because of your operations, that points to general liability. If a client could lose money because of your advice, design, analysis or a missed commitment, that points to professional liability. Many businesses have both kinds of exposure, such as a contractor who installs work and also advises on it.

A certificate request from a client or landlord, a contract that lists required coverages or a licensing rule can all bring the question up. In each case, bring the paper to your agent.

What does general liability insurance cover?

A standard commercial general liability (CGL) policy has three parts, according to the Insurance Information Institute (opens in a new tab):

• Coverage A, bodily injury and property damage liability. Pays for covered injury or damage caused by an accident at your premises or because of your operations, subject to the policy's terms, limits and exclusions.
• Coverage B, personal and advertising injury liability. Covers listed offenses such as libel or slander, privacy violations and advertising-related offenses, as the policy words them.
• Coverage C, medical payments. Pays limited medical expenses for a qualifying injury without anyone having to sue first.

Exclusions shape what general liability is worth to your business. Common ones include expected or intended injury, workers' compensation and employer's liability, pollution, aircraft, auto and watercraft, damage to your own property, damage to property in your care, custody or control, damage to your own product or work, product recalls, some electronic data losses and professional services. The exact list depends on the form edition and endorsements on your policy, so ask to see the exclusions that apply to the work you described.

That last exclusion matters here. A general liability policy is not built to answer a claim that your professional advice caused a client's financial loss.

What does professional liability insurance cover?

Professional liability responds to allegations that your professional services involved negligence, an error, an omission, inaccurate advice, misrepresentation or failure to perform an agreed service, along with the financial loss that followed. It can pay defense costs and judgments up to the policy limit, per the Insurance Information Institute (opens in a new tab), subject to the policy's terms.

There is no single standard form the way there is for CGL. Professional liability wording is written by each insurer and varies by occupation, endorsements, exclusions, how a claim is defined, how defense costs are treated, the retroactive date and whether coverage is claims-made or occurrence-based. Intentional or dishonest acts fall outside it. Whether it responds to bodily injury, property damage, cyber events, contractual liability, punitive damages or regulatory matters depends on the wording and endorsements, so those become questions for the insurer, one by one.

How do the two coverages differ in real business situations?

These examples from The Hartford's comparison of general liability and errors and omissions (opens in a new tab) show the split:

• A customer trips over a box at your location. That is bodily injury from premises or operations, which is the general liability side.
• A bookkeeper's mistake costs a client money. That is a professional-service financial loss, the E&O side.
• Real estate agents fail to give a client the updates they agreed to provide. That is an E&O example.
• A programmer's error exposes a client's computer to a virus and the client loses files. That is a professional liability example, and the cyber wording in the policy needs its own review.
• An advertisement triggers a qualifying copyright or reputation claim. That falls under personal and advertising injury in general liability.

One event can carry more than one legal theory. A damaged client computer could be alleged as property damage and as a professional error at the same time, and the facts, exclusions and endorsements decide which policy responds. Describe the full situation to your agent and ask how each policy would treat it.

When might a business carry both?

A business carries both when it has physical exposures and sells advice or services. A contractor who installs work and also designs it, or a consultant who meets clients at their offices, fits that description. Which combination fits depends on the facts of your work, your contracts and any licensing rules, and an agent can test those facts against specific policy forms.

An LLC is a business structure and not a type of work, so an LLC's coverage questions come from what it does. The same is true for freelancers and independent contractors.

What does a business owners policy include?

A BOP packages property insurance, business liability coverage and business interruption coverage (opens in a new tab) for eligible small and medium-sized businesses. The liability piece covers bodily injury, property damage and personal or advertising injury from covered business risks. Professional liability sits outside the standard package and can be added by endorsement, through a commercial package policy or as a separate policy, per the Insurance Information Institute.

In practice, that means a BOP can supply the general liability side and the property side, while professional services, cyber risk, vehicles, employee injuries, pollution and some property items may need separate coverage. An umbrella or excess policy can raise limits on underlying coverage, depending on its wording, and it does not fill every professional liability gap on its own.

What does claims-made professional liability mean?

Most professional liability is written on a claims-made basis. The policy responds when the claim is made and reported during the policy period, subject to its conditions and any retroactive date. Occurrence coverage, the style used in standard CGL, responds based on when the injury or damage happened.

Three terms drive claims-made coverage (NAIC Issue Paper No. 65 (opens in a new tab)):

• Retroactive date. Work before this date may be excluded even if the claim arrives during the policy period.
• Prior acts. Coverage for work done before the policy began, where the policy provides it.
• Extended reporting period. Often called tail coverage, it lets certain claims be reported after the policy ends when the work happened during the covered period. Length, trigger, cost and scope depend on the policy.

These terms matter most when you change insurers, let a policy lapse, close the business or retire. Some states add their own rules for these policies, so ask your agent what applies where the policy is issued. For example, Connecticut requires claims-made professional liability policies issued in the state to include prior-acts coverage and a right to buy equivalent coverage for claims from the insured policy period (Conn. Gen. Stat. § 38a-394 (opens in a new tab)).

What does a certificate of insurance prove?

A certificate of insurance is evidence, for the certificate holder, that the named insured has the type and amount of insurance shown. A certificate may be needed when a contractual or statutory requirement calls for evidence of insurance (opens in a new tab), according to Connecticut's State Insurance and Risk Management Board. Clients, landlords, property managers, general contractors, government agencies, lenders and event venues all ask for them.

A certificate lists the named insured, insurer, policy numbers, effective and expiration dates, coverage types and limits. It is not the policy. It does not amend coverage, add an insured, remove an exclusion, extend a date or promise the policy stays active. A requester can ask for additional insured status, and that status exists only if the policy or an endorsement provides it. When a contract asks for additional insured wording, primary and noncontributory wording, a waiver of subrogation or specific limits, send the contract to your agent and ask which endorsements it needs.

When does a law require professional liability insurance?

Requirements are occupation-specific, and they come from each state's statutes, licensing boards and contracts. Your state insurance department (opens in a new tab) can point you to the insurance statutes, and your licensing board can confirm the rule for your occupation.

For a consultant, designer, software developer, accountant or ordinary LLC, the requirement comes from a specific licensing rule, a contract, a lender, a landlord or a customer.

Two examples show how narrow these rules are. Connecticut requires physicians providing direct patient care to carry professional liability insurance or other indemnity, with minimums of $500,000 per person per occurrence and at least $1,500,000 in the aggregate, subject to the section's exceptions (Conn. Gen. Stat. § 20-11b (opens in a new tab)). Kentucky requires active real estate licensees to carry E&O under KRS 324.395 (opens in a new tab), with minimums of $100,000 per claim and $1,000,000 annual aggregate under 201 KAR 11:220 (opens in a new tab). Each is a rule for one occupation in one state. For a business based in Connecticut, the Connecticut small business insurance guide covers more of what the state requires.

What should a business owner ask an agent?

Gather these before the call: the written insurance requirements from every client, landlord, lender or contracting authority; a list of every service and product; where the work happens and whether customers visit; property belonging to clients that you hold; employees, subcontractors and independent contractors; the date your professional services began; and prior policies, certificates, claims, demands and incident notices. Then ask:

• Does this proposal show general liability, professional liability or both, and what does each one exclude for the work I described?
• Is the professional liability claims-made or occurrence-based, and what are the retroactive date, prior-acts coverage and extended reporting options?
• Do defense costs reduce the limit?
• Are the requested limits per occurrence, per claim or aggregate?
• Does the certificate holder need additional insured status, and which endorsement provides it?
• Does the policy apply to subcontractors, client property, client data and completed work?
• Does the BOP include only general liability, or is professional liability endorsed onto it?
• Are workers' compensation, commercial auto, cyber, property, inland marine, pollution or bonds separate issues for my business?
• What business changes do I need to report to the insurer?

Frequently asked questions

Does an LLC need professional liability insurance?

The need comes from the occupation, a licensing rule or a client contract, so check the contract and your licensing board first, then describe the services to an agent.

How much does a $1,000,000 general liability policy cost?

Premiums depend on the business's operations, location, payroll or revenue, claims history and the policy's terms, so a single figure would describe someone else's business. Ask an agent to quote the limit your contract names and to show the deductible and exclusions beside the price.

What is not covered by professional liability insurance?

Intentional or dishonest acts fall outside professional liability. Bodily injury, property damage, cyber events, contractual liability, punitive damages and regulatory matters depend on the policy's wording and endorsements, so ask the insurer how each one is treated.

Is professional liability the same as errors and omissions insurance?

Yes, they are two names for the same type of coverage. Wording still differs from insurer to insurer, so compare the forms and not just the label.

Your next step

Take your questions and your contract to a licensed agency, and check the agent's license with your state insurance department (opens in a new tab) before you share details. Bring the certificate request or contract language with you, since those documents tell the agent which coverages and endorsements to price. You can search agencies by state in the Riskado agency directory.
