Professional liability insurance is business insurance that protects you if a client files a lawsuit over an alleged mistake or bad piece of advice. It’s also known as errors and omissions insurance.
If you provide services to clients for a fee, you should have professional liability insurance. Here’s what this insurance covers and where to shop for coverage.
What does professional liability insurance cover?
Professional liability insurance is also called errors and omissions insurance. It can protect businesses against the following kinds of claims, including covering legal and settlement costs:
Professional negligence or failure to meet a standard of care. Say an architecture firm designs a branch for a local bank. A year later, the bank is sued by a customer because the branch’s bathrooms aren’t compliant with the Americans with Disabilities Act, or ADA. The bank could sue the architecture firm for failing to adhere to professional standards. Read more about architect insurance.
Failure to deliver a promised service on time. Say a manufacturing plant hires an IT consultant to handle a cybersecurity upgrade. The consultant promises it’ll be finished by the end of the year, but they can’t stick to that timeline. In January — after the project was supposed to be completed, according to the contract — the plant gets hacked. The plant could sue the consultant to recoup the costs of recovering from the security breach. Read more about professional liability insurance for consultants.
Breach of contract. If an insurance agency’s contract says it will help clients settle claims but, when the time comes, it doesn’t have enough staff to provide that service, clients could claim that the agency violated that contract. Read more about E&O insurance for insurance agents.
Errors. Medical malpractice insurance is a type of professional liability insurance that protects against claims of professional errors. For instance, if a nurse administers the wrong dosage of a medication to a patient, they could be sued by that patient or their family. Read more about how much medical malpractice insurance costs.
General professional misconduct. If a college professor routinely grades one student harder than their peers and that student can’t graduate on time, that student or their parents might file a claim against the educator.
Professional liability insurance protects your business regardless of whether legal claims are found to have merit. Your policy can pay out in case of frivolous lawsuits as well as substantiated ones.
Unlike some other types of liability insurance, professional liability policies generally protect against claims of financial losses, not bodily injury or property damage. Medical malpractice insurance is an exception to that rule, though, as are policies for architects and engineers.
What isn’t covered by professional liability insurance?
Professional liability doesn't protect a business against:
Bodily injury or property damage that customers or clients suffer while you’re doing business; for instance, if they trip and fall in your office or if their personal files are destroyed in a fire. Those are general liability insurance claims.
Lawsuits filed by employees with allegations like wrongful termination or workplace harassment. For those, a business will need employment practices liability insurance.
Fraud or criminal action. If you or one of your employees commits a crime or intentionally misleads a client, the resulting professional liability claim isn’t covered.
Who needs professional liability insurance?
Anyone who provides professional services or advice to clients for a fee faces the risks that professional liability insurance protects against. This list can include:
Consultants, including management and IT consultants.
Financial or investment advisors.
Insurance and real estate agents and brokers.
Software developers and graphic designers.
Medical professionals may be required by law to carry medical malpractice insurance. This kind of professional liability insurance specifically protects physicians, dentists, nurses, psychologists and other medical professionals against claims that they made a mistake that led to a patient’s injury or death.
Professional liability insurance may be required in other fields as well. For example, state licensing bodies may require lawyers to carry legal malpractice insurance or to tell clients whether or not they have it.
How much is professional liability insurance?
The median cost of professional liability insurance is $59 per month, according to online insurance marketplace Insureon, but prices can vary. For instance, new Progressive insurance customers paid a median of $42 per month in 2021, according to that company.
The cost of professional liability insurance depends on:
How common lawsuits are in your industry.
The location where you work and how common claims are there.
How much coverage you need.
How many employees you have.
How long you’ve been in business.
What kind of claims, if any, you’ve filed in the past.

Business insurance ratings methodology
NerdWallet’s business insurance ratings reward companies that offer small-business owners reliability and ease of use. Ratings are based on weighted averages of scores in several categories, including financial strength, customer complaint data, shopping experience and customer service. Learn more about how we rate small-business insurance companies.
These ratings are a guide, but insurance policy details and prices can vary widely from business to business and provider to provider. We encourage you to shop around and compare several insurance quotes.

Insurer complaints methodology
NerdWallet examined complaints received by state insurance regulators and reported to the National Association of Insurance Commissioners in 2018-2021.
To assess how insurers compare to one another, the NAIC calculates a complaint index each year for each subsidiary, measuring its share of total complaints relative to its size, or share of total premiums in the industry. To evaluate a company’s complaint history, NerdWallet calculated a similar index for each insurer, weighted by market shares of each subsidiary, over the three-year period.
Our star ratings consider ratios for both general liability insurance and commercial property insurance. When an insurer sells policies that are underwritten by several different insurance companies, we consider the NAIC complaint ratios of all the underwriters.
