Top professional liability insurance companies by industry
Professional liability insurance provides financial protection if a client claims your professional mistake, negligence, or oversight caused them financial loss. That’s why it’s important to work with an insurer that understands your industry.
The right insurer can make sure all of your unique risks are covered, whether you’re an independent contractor or you have a team of employees.
Here are the best professional liability insurance carriers for our top industries:
IT / technology
The Hartford and PHLY are reliable, top-rated professional liability insurance providers for tech companies, although in this industry it’s called errors and omissions insurance. This coverage is often bundled with cyber liability insurance in a policy called tech E&O, also known as tech professional liability insurance, which typically costs less than purchasing each policy individually.
Tech E&O insurance protects tech companies if a mistake, software bug, or service failure causes a client to lose money. For example, a cybersecurity company is hired to enhance a childcare center's network security. If the childcare center suffers a data breach and sues for negligence, tech E&O will cover the cybersecurity business's legal expenses.
Consultants
Top insurance providers for consultants include Hiscox, PHLY, and The Hartford.
Businesses often hire management consultants, IT consultants, and other consulting experts to help them improve processes and increase profits. But that also makes them a target for accusations of bad advice and professional mistakes. Professional liability helps cover the cost of legal battles and frivolous lawsuits from dissatisfied customers trying to recoup their losses.
Healthcare
Many healthcare providers trust Hiscox for professional liability coverage. However, in this field, it’s called medical malpractice insurance. CM&F Group is another top-rated carrier, offering malpractice policies written by The Medical Protective Company (the name you'd see on your policy).
Unlike standard professional liability insurance, malpractice insurance covers claims that your work caused bodily injury or worsened a patient's condition. For example, it would cover a chiropractor’s legal defense costs if a patient sues them for increasing their back pain.
Accountants
Accountants often choose Hiscox and The Hartford for professional liability coverage.
If a client claims you missed a deadline for filing their tax forms or your advice cost them money, this policy can help pay legal fees, including court costs, settlements, and judgments.
Engineers
The Hartford and Hiscox are popular professional liability providers for engineers.
Just one mistake in a structure’s integrity or design could cost a client hundreds of thousands of dollars, making professional negligence claims an expensive issue for engineers and architects. Even if you’re not directly at fault, you could still face a pricey lawsuit from a disgruntled client.
Best professional liability insurance companies by state
While many insurance companies sell professional liability insurance nationwide, some are only licensed to sell in certain states. Depending on where your business is located, your state could impact who you buy insurance from.
For TechInsurance customers, these are the insurers that sell the most professional liability policies in our top states:

What risks do businesses face without professional liability insurance?
Real estate agents, event planners, law firms, and other professional service providers often need professional liability insurance to fulfill contract requirements, get licensed, work in certain facilities, or compete for clients who prefer insured providers. Depending on your industry and location, you may also need to carry a policy to comply with state laws.
However, even if professional liability isn’t required, many businesses carry it in case a client sues you for claims like:
- Breach of contract
- Incomplete work
- Missed deadlines or failure to deliver services
- Claims of negligence
- Misrepresentation
Professional liability will pay for your legal expenses, including attorney’s fees, settlements, and judgments. Without coverage, you could be stuck paying for these expenses out of pocket.
Keep in mind, professional liability only covers claims related to your professional services. For other common business risks, like a vendor suffering a personal injury at your office or accidental property damage by you or an employee, you’d need a general liability policy.
