Best errors and omissions insurance providers by industry

Because errors and omissions insurance covers the specific risks of your professional work, your industry is a key factor. You'll need a provider that can make sure you're covered for the right exposures. In fact, some only cover certain types of professionals.

The right carrier can help make sure you're covered for the relevant risks, whether you're a business owner with employees or an independent contractor. They can also help you comply with any requirements for E&O insurance, such as state laws that might mandate coverage for your profession.

Here are the recommended E&O insurance providers for our top industries:

Insurance professional icon

Insurance agents

Insurance agents often depend on Hiscox for their errors and omissions insurance policies.

Some states require agents, brokers, and other licensed insurance professionals to carry E&O insurance, which is why it's important to work with a carrier that knows your line of work. They can make sure your policy matches the laws in your state and the unique risks of your profession.

If an error results in a gap in your client's coverage, you could face a lawsuit. An E&O policy would cover your legal defense costs, such as court costs and witness fees.

Information technology icon

IT and technology professionals

Tech companies and contractors typically need more than a standard E&O insurance policy. Instead, they often buy technology errors and omissions insurance, or tech E&O, which bundles E&O insurance with cyber insurance.

This bundle extends the protection offered by E&O to include errors and oversights that lead to a data breach or a cyberattack at a client's business.

Fortunately, several carriers specialize in tech E&O for small businesses, including PHLY and The Hartford.

Real estate icon

Real estate professionals

Hiscox and Travelers can help you find the right E&O policy for your real estate business.

State laws often require real estate agents and brokers to carry E&O insurance. Even when it's not required by law, Realtors may need this coverage to work with a particular agency.

A carrier that specializes in real estate insurance can help you find a policy that matches your requirements and the specific risks you face. For example, you'll want coverage for discrepancies in MLS listings, failure to disclose, documentation errors, and similar types of claims.

Consultants

Consultants have a wide range of choices when it comes to small business insurance carriers, including Hiscox, PHLY, and The Hartford.

These providers can help you find coverage for common client claims in consulting, such as a breach of contract or poor advice that causes a client to lose money.

Consulting firms and clients often require consultants to carry E&O insurance, more commonly called professional liability coverage in this industry. Your carrier will help make sure your policy fulfills these requirements, so you can sign contracts and gain the protection you need to work with larger clients.

Finance & accounting icon

Finance professionals

Financial services businesses often depend on Hiscox and Travelers for their E&O coverage, which protects against accounting errors or poor advice that causes a client to lose money.

If a tax preparer misses a filing deadline or makes an error on a tax form, this policy can help pay for their legal expenses or settlement. It also protects bookkeepers against costs related to data entry errors and lost financial records.

Professional associations and state laws often require E&O insurance for accountants. For example, public accounting firms in Ohio must carry a certain amount of E&O coverage, with the amount dependent on the size of the firm.

Best errors and omissions insurance providers by state

Your state is another important factor when choosing an E&O carrier. While many insurance companies provide national coverage, others cover only a specific territory that could exclude your business's location.

What are the risks of not having E&O insurance coverage?

If you work in a field where an errors and omissions insurance policy is required by law, going without coverage could result in hefty fines and penalties. In certain professions, you might even lose your license.

Additionally, you might miss out on clients who want you to carry this coverage. They might choose to work with a competitor who is insured rather than risk having to face expensive legal fees.

Beyond this, perhaps the biggest risk is to your own business. Without E&O insurance, a simple mistake could lead to costly out-of-pocket expenses that could force your business to close.

Errors and omissions insurance covers claims related to:

  • Mistakes and oversights
  • Missed deadlines
  • Breach of contract
  • Misrepresentation

These liability claims are a tremendous risk for businesses that provide professional services or advice, bringing financial losses that could bankrupt your business. A comprehensive risk management strategy includes both insurance to cover claims and reducing the liabilities that lead to common claims.
