One mistake shouldn't cost you everything.

Learn more about how a good E&O policy is essential to protecting your business, whether you’re a solo consultant or a growing firm.

What is errors and omissions (E&O) insurance?

Errors and omissions insurance, also called professional liability insurance, protects your business if a client claims your work, advice, or services caused them a financial loss. It covers your legal defense costs, settlements, and judgments, whether or not the claim has merit.

Even if you did nothing wrong, defending yourself in court is expensive. E&O makes sure a lawsuit doesn't become a business-ending event.

In Massachusetts, E&O is required by law for certain professions, and increasingly expected by clients and contracts across many others. If your business provides a professional service or expert advice, this coverage is worth having.

Finding the right coverage at the right price shouldn't be complicated. At Nobile, we make it easy to get coverage that works for you.

What's covered with an E&O policy

Last updated May 2026

Professional Negligence

  • Covers claims that your work, advice, or services fell below the expected standard of care and caused a client financial harm, even if the allegation is unfounded.

Errors and Oversights

  • If a mistake in your work, like a miscalculation, a missed detail, or an incorrect recommendation, results in a financial loss for a client, your E&O policy steps in to cover the fallout.

Missed Deadlines

  • If failing to deliver work on time causes a client financial damage, E&O can cover the resulting claim.

Legal Defense Costs

  • Covers attorney fees, court costs, and other legal expenses regardless of how the case is resolved. Lawsuits are expensive even when you win.

Settlements and Judgments

  • If a claim results in a settlement or court judgment against your business, your E&O policy covers those costs up to your policy limits.

Important to note: E&O insurance covers financial losses to clients and not bodily injury or property damage. Those are covered under general liability. Ask us what’s actually covered in your policy.

Who needs an E&O policy?

If your business provides a professional service, gives advice, or delivers work a client relies on financially, you need E&O coverage.

This includes:

  • Consultants and advisors

  • Accountants and bookkeepers

  • IT and technology professionals

  • Architects and engineers

  • Real estate agents and brokers

  • Insurance agents

Ways to save on E&O insurance

There are a few ways that you can save on E&O insurance with Nobile.

Maintain a clean claims history.

  • Your history of past claims is one of the biggest factors in your premium. Fewer claims over time means lower rates at renewal.

Document everything.

  • Good documentation practices reduce your exposure to claims in the first place. Carriers take note of businesses with solid contracts, clear scope of work agreements, and consistent client communication.

Bundle your policies.

  • Carrying your E&O alongside a BOP or general liability policy with the same carrier can qualify you for a multi-policy discount.

Ask about carrier-specific discounts.

  • Many carriers offer additional savings programs. We'll help you find every discount you're eligible for.

E&O FAQs

  • Yes. Errors and omissions insurance and professional liability insurance are the same thing. Depending on your industry, you may also see it called malpractice insurance. The name changes by profession, but the protection is essentially the same.

  • It depends on your profession. In Massachusetts, LLCs and LLPs are required to carry professional liability coverage. Home inspectors must carry a minimum of $250,000 in aggregate E&O coverage. For other professions like real estate agents and attorneys, it may not be legally required but is strongly recommended, and clients or contracts may require it regardless.

  • Yes. E&O covers your legal defense costs even if the claim against you has no merit. That's one of its most important features. Lawsuits are expensive whether you're at fault or not.

  • No. A BOP covers general liability and property, but does not include professional liability. E&O is always a separate policy. We can write both for you.

  • E&O is designed specifically for financial harm caused by your professional services. It does not cover bodily injury or property damage to third parties.
