There’s no such thing as a one-size-fits-all professional liability policy. Every business owner’s circumstances and needs are unique, which is why the best professional liability insurance companies have customizable coverages that can be tailored to different situations. Other characteristics of the best providers include strong financial ratings and excellent customer support for general policy questions and claims.
With those items in mind, I evaluated more than a dozen different insurance providers using a proprietary rubric and came up with the following six best professional liability insurance companies:
| Provider | Best for | Financial rating |
|---|---|---|
| Simply Business | Easy quote comparison | A++ (Superior) |
| ERGO - Next Insurance | Quick claims resolution | A- (Excellent) |

Simply Business: Best overall for easy quote comparison
Why I like it
Comparing insurance quotes across multiple companies can save you money, but it can also be a hassle. That’s where Simply Business comes in handy, as the broker partners with over a dozen different insurance carriers to provide you multiple quotes with just a single application. Unlike some brokers, you’ll be able to see real-time adjustments to premiums as you adjust coverages.
The process of getting a quote is quick and easy. When I tested it myself, I was able to get a quote within minutes, all without the need to speak to an agent, although that is an option if you have questions or prefer some guidance in purchasing a policy.
Simply Business did lose a few points because, as a broker, it doesn’t handle claims directly. Claims are handled through the insurance carrier you ultimately end up selecting. It also lacks a 24/7 call center. If that’s important to you, then you may want to consider a company like The Hartford, which does have around-the-clock claims support.
Cost, coverage & other deciding factors
| Cost | In getting a quote for professional liability insurance, I applied as a notary public in Texas. I received three quotes in just five minutes, with policies ranging from $23 to $61 per month. They had the same professional liability coverage amount of $1 million. |
|---|---|
| Coverage |
|
| Convenience |
|
| Customer satisfaction | Users are happy with their experience.

ERGO – Next Insurance: Best for quick claims resolution
Why I like it
ERGO – Next Insurance stood out to me for its commitment to handling claims quickly, which is within 48 hours once all paperwork is submitted. While this isn’t an official guarantee, many customer reviews do confirm that the company often meets that timeline. This level of efficiency is a major part of why it scored so well in my evaluation. Claims can be filed online or via its mobile app, with the ability to track status 24/7.
Affordability is another strong point of ERGO – Next Insurance. After doing some research, I found that some of its customers pay as low as $19 per month, with more than half paying under $55. And as an additional datapoint, in 2024, only 11% of its customers paid over $75 per month.
With all that said, one potential limitation you may run into is the fact that businesses with more than $5 million in revenue may be ineligible for coverage. If you find this to be the case, consider another insurance company like Thimble
Cost, coverage & other deciding factors
| Cost | Simply answer a few questions about your business, and within about 10 minutes, you'll have a quote. Often, when getting a quote, ERGO - Next Insurance will give you three tiers of coverage: Basic, Premier, and Deluxe. While not the same as comparing a quote, this method does give you some flexibility in finding coverage that is right for your business. |
|---|---|
| Coverage |
|
| Convenience |
|
| Customer satisfaction | Customers are happy overall.
Negative reviews are few and far between — and for all the ones we located, ERGO - Next Insurance responded, addressing the issue. |

The Hartford: Best for supplementary coverages
Why I like it
To me, The Hartford stands out as an excellent insurer to do business with if you also have other insurance needs. It is an incredibly large company, and therefore, has a wide range of supplementary insurance coverages beyond just the basic professional liability protection. Examples include business interruption, commercial flood, data breach insurance, employment practices liability, home-based insurance, and inland marine.
Additionally, it can cover businesses in nearly any industry, such as healthcare, marketing, construction, and consulting. The bottom line here is that by going with The Hartford, you can more easily house all of your insurance needs under the same umbrella, which is one way to simplify your finances. And when you get a quote, you can easily adjust policy coverages to get just the right amount of coverage.
The Hartford also has 24/7 claims support, an in-house claims team, and the option to get quotes and purchase policies online. All of those are items that helped it score highly in my evaluation. With that said, its account management tools may not be the most technologically advanced, but rather, there’s more of an emphasis on functionality.
Cost, coverage & other deciding factors
| Cost | According to The Hartford, a miscellaneous E&O policy costs $76 monthly. Here are some monthly averages for professional liability by niche:
After answering a few questions, I received a quote in line with its published prices, which was $1,378 annually. The policy carried a total limit of $1 million with a $1,000 deductible, and the quote came with multiple options, including limits of up to $2 million and a deductible of up to $25,000. The Hartford even included an informational note that if I purchased general liability insurance, I could bundle it with professional liability coverage and most likely reduce the total cost. |
|---|---|
| Coverage |
|
| Convenience |
|
| Customer satisfaction | Customers have given it positive marks.
It also works with independent agents who have rated it as one of the best carriers to work with, per a 2024 J.D. Power survey. |

Hiscox: Best for allied healthcare professionals
Why I like it
Dedicated small business insurer Hiscox has a wide range of professional liability policies available. The policies target allied healthcare professionals, engineers, and inspectors and offer medical malpractice E&O insurance and a miscellaneous professional liability policy.
The policy — which can be packaged with other coverages like general liability, cyber, and business property — is available for all healthcare workers, including those in counseling, home healthcare, spas, medical imaging, and speech therapy. Hiscox includes global coverage, so if you happen to be a medical professional who does nonprofit work abroad, it can build coverage for that. In that event, you must file the claim in the US.
Hiscox is a great option for professional liability insurance, and since it’s a traditional carrier, you’ll have just one point of contact throughout the life of the policy. However, it doesn’t have any weekend or after-hours options for calling. If your business operates on the weekend and wants the ability to call and speak with someone 24/7, The Hartford is a good option since it maintains a 24/7 call center.
Cost, coverage & other deciding factors
| Cost | We received a quote online for $90.55 monthly or $1,087 annually.
On professional liability insurance, independent contractors are considered insured. |
|---|---|
| Coverage |
|
| Convenience |
|
| Customer satisfaction | Small businesses, on average, seem to be happy with it.

biBERK: Best for administrative services for professional liability
Why I like it
Dedicated small business insurer biBERK is the best for businesses offering administrative services because those industries fit within the provider’s specific appetite. This means there is a very high probability of getting a successful quote with coverage focused specifically on administrative services. Plus, you have a good chance of getting a quote online, too.
The relatively low score in my evaluation of biBERK’s financial stability is not a reflection of its AM Best rating. Instead, it’s because for most coverages, biBERK is a regional carrier available in fewer than 30 states.
While it will often offer a tiered quote structure similar to Next Insurance, the coverage is still from the same provider. If you’d prefer to compare quotes in an online marketplace, then consider the broker Simply Business.
Cost, coverage & other deciding factors
| Cost | I received a quote for a public notary business that costs $184.92 monthly. Alternatively, if I paid for the entire year, I would pay $1,996 and save over $200. This quote was for $1 million in professional liability coverage, both per occurrence and aggregate. Each occurrence carried a deductible of $1,000. The coverage was for the next day and not same-day coverage. |
|---|---|

| Convenience | In 2015, the Berkshire Hathaway Insurance Group launched biBERK, which has sold over 200,000 small business insurance policies, to offer insurance for small businesses quickly and conveniently. It certainly does that, as it
Beyond the convenience of its quote and bind system, it does offer a few other online services to its policyholders. It lets you
Its professional liability insurance is available in all 50 states. However, other coverage is spottier, so I recommend checking biBERK's coverage map in case you're looking for insurance beyond professional liability. |
| Customer satisfaction | Policyholders are, overall, satisfied.

Thimble: Best for short-term or flexible coverage
Why I like it
For me, one of the coolest features about Thimble is the fact that it can offer insurance coverage by the hour, day, month, year, or job. In other words, it’s great if you don’t work year-round and only need coverage from time to time. Other insurance companies, by comparison, would typically require you to cancel the policy, something that’s far less convenient, not to mention less cost-effective.
Thimble is also a great option for those just starting out. As a bit of background, Thimble made a large move toward insuring businesses during the pandemic, a time when there was a surge in newly established companies. And it did so while still offering affordable pricing.
Ever since then, Thimble has continued to specialize in offering affordable, quality coverage for home-based businesses, newer companies, small businesses with little or no employees, and those with a shorter history of revenue. The only points lost in my evaluation were due to the lack of a 24/7 call center and the fact that some of its carriers have a financial rating of an A-.
Cost, coverage & other deciding factors
| Cost | Getting a quote from Thimble was incredibly easy, a process that only took me five minutes. However, I was unable to obtain a quote specifically for professional liability coverage. Thimble does note that coverage may vary by state and industry, so this won't be the case for everyone. However, it does also state that small business owners, on average, pay around $45 per month to get covered. |
|---|---|
| Coverage |
|
| Convenience |
|
| Customer satisfaction | Good, overall.
Notably, Thimble responds to 70% of negative reviews, a much higher figure than I'm used to seeing. I take that as a great sign that the company does listen to its customers. |

How I evaluated the best professional liability insurance companies
The best professional liability insurance companies were evaluated in four main categories.
- Financial stability: Using ratings from AM Best, this was used as a litmus test for an insurance carrier’s likelihood of being able to pay out claims in the event that an unusually large portion of its customer base requested payouts at the same time.
- Customer satisfaction: Here, I considered a customer’s experience from start to finish. This included the ease of getting a quote, getting answers to questions, purchasing a policy, and what the claims experience would be like. I also evaluated online reviews and ratings from reputable third-party review sites, such as the BBB and Trustpilot.
- Convenience: I assessed the ability to manage an existing policy easily. For example, this considered the availability and ease of use of things like a mobile app and an online dashboard, as well as the ability to quickly and easily make changes to a policy.
- Policies offered: In addition to professional liability insurance, I considered whether the carrier had other coverages available as well, as having multiple options is something that would make it easier to bundle policies they might commonly need.
Frequently asked questions (FAQs)
What does professional liability insurance cover?
Professional liability insurance is a type of liability insurance that provides financial assistance and protects your company assets when someone claims financial or physical harm as a result of your advice or service or alleges that a contract has been broken. It is different from general liability insurance, which focuses on property damage or bodily injury someone experiences as a result of your business operations.
Is professional liability different from E&O insurance?
No, professional liability is sometimes referred to as E&O insurance. It provides the same coverage as professional liability: errors or omissions made by your company during the course of work.
What are the different types of professional liability insurance?
There are lots of different types of professional liability insurance. The other name, errors and omissions (E&O) insurance, causes confusion, but these are the same thing. However, there is tech E&O insurance, which is different from your standard professional liability policy with cyber liability insurance elements present in it. Another type of E&O insurance is medical malpractice insurance, which has a few different policy language elements and is for those actively practicing medicine.
How much does professional liability insurance cost?
Professional liability insurance costs depend on several factors, including the business, risk, revenue, and claims history. The quotes we received ranged from $1,000 to over $1,600 annually for a design firm policy.
What is a retroactive date in professional liability insurance?
A retroactive date is the date when coverage begins. You can select a date that may actually precede the date you are shopping for coverage. States have a statute of limitations to file a claim, and so an incident can happen and you may not receive notice of it for a year or more. Insurers use a retroactive date to establish a clear coverage period for your business.
How is general liability insurance different from professional liability insurance?
General liability provides coverage for property damage or bodily injury to third parties. Professional liability, on the other hand, is focused on errors related to your business or a failure to maintain a contract or service agreement. This makes the coverage crucial for professionals who need professional liability insurance, such as consultants, notaries, medical providers, and real estate agents.
