Engineers must get it right one hundred percent of the time. If they fail, human lives, buildings, bridges, and other critical assets could be at risk.

Still, even the most careful and by the book engineers and engineering firms make mistakes. These mistakes — whether the result of a bad design, faulty materials, or human error — often result in costly lawsuits. 

The best way for engineers to protect against lawsuits is to get professional liability insurance, which can help cover legal, defense, and settlement costs if an engineer or engineering firm is ever sued.

In this article I’ll explain everything engineers and engineering firms need to know to get the right professional liability protection to meet their needs and reveal the 6 best professional insurers for engineers.

What is professional liability insurance for engineers?

Even if you’re the absolute best at what you do, engineers make mistakes and unintentional errors. If a client believes a mistake or error committed by you or an employee while providing engineering services to them resulted in a financial loss or other harm, they can sue you.

Professional liability insurance helps cover you and your engineering business if you or someone who works for you makes a mistake when providing professional services that has a negative impact on a person you provide the services to. This coverage is also known as:

  • Professional indemnity insurance for engineers
  • Errors and omissions insurance for professional engineers
  • E&O insurance for engineers.

If you don’t have professional liability coverage and are sued, you are responsible for paying legal and settlement costs out of pocket. In most cases, these can be high enough to bankrupt an engineer or engineering business.

What does engineering professional liability insurance cover?

Professional liability insurance helps cover claims related to things like:

  • Mistakes or negligence. Services provided (or not provided) by your company that aren’t what the client expects and result in a lawsuit or judgment against your business.
  • Misrepresentation. This includes making claims to clients or saying things to them that aren’t completely true.
  • Inaccurate or incorrect advice. Providing advice or direction to a client that causes them harm.
  • Copyright infringement. This includes copyright law issues, mistakes, oversights, and misunderstandings.
  • Personal injury. This encompasses all types of physical harm caused by services provided by you or the people who work for you.

If your engineering business gets sued, this coverage can help pay for your:

  • Legal costs
  • Defense fees
  • Judgments
  • Settlements.

Even if you don’t do anything wrong, a client is still able to sue your business if they think you made a mistake or did not provide adequate engineering services. Without professional liability insurance, you will have to pay the costs to legally defend yourself out of pocket, even if you’re found innocent. Costs related to these kinds of lawsuits are typically high, even if you did absolutely nothing wrong.

Here are some scenarios that professional liability insurance can help with:

  • A building was built incorrectly because you used wrong dimensions in your design for it.
  • Your client’s storage building collapsed because of your firm’s design and destroyed all their inventory.
  • An engineer who works for you provides inaccurate advice because they did not fully inspect a property before construction.

In each case, the business is sued for the mistake they made.

Professional liability insurance doesn’t cover everything related to business mistakes. It won’t cover the following types of claims: 

How does professional liability insurance for engineers work?

Professional liability insurance has an added layer of complexity that many other business-related policies don’t have. 

Typical business insurance only covers claims when the policies are in effect. Most professional liability policies are based on when claims are made with a retroactive date and extended reporting period.

  • The retroactive date means the policy holder is covered for incidents that happen on or after a specified date.
  • The extended reporting period covers claims filed during a specified time after the policy expires. This is usually a 30 to 60 day period, but it can be extended to a year or more for an additional cost.

An insurance company will actually cover claims made against a business during the period the engineer professional liability policy is effective, or within its retroactive date or extended reporting period. Other than this, you should contact your insurance provider as you would for any other type of insurance when you need to make a claim.

What other types of insurance do engineers need?

Professional liability insurance for engineers doesn’t cover everything. You’ll need to purchase other types of insurance to get complete coverage for your engineering business. Some types of coverage engineers typically get include:

  • General liability insurance to help protect your business from claims that it caused:
    • Damage to someone else’s property or belongings
    • Injuries that happen to clients on your business property.
  • Workers’ compensation insurance, which helps your employees recover from work related injuries or illnesses. This coverage provides benefits that can help pay for:
    • Medical bills
    • Ongoing care costs, including surgery or physical therapy
    • Lost wages
    • Death benefits to immediate family members in case an employee passes away due to an on the job incident.
  • Commercial property insurance, which helps protect your owned or rented buildings and other property used to operate your engineering business. This includes:
    • Business equipment 
    • Computers
    • Tools
    • Office furniture
    • Supplies
    • And more.
  • Commercial auto insurance will protect you and your employees when you drive a company owned or personal vehicle for work reasons. Personal auto coverage will not pay for accident damage if you’re driving for work purposes. Learn more at the best commercial auto insurance companies.

How much does professional liability insurance for engineers cost?

Every engineering business is unique, so the professional liability insurance cost for them varies. Coverage typically ranges between $150 and $6,00 a year per engineer, but your premium cost depends on different factors, including:

  • Coverage limits
  • Deductible amount
  • Years in business
  • Claims history

What’s important is that you get quotes from several of the insurers on our list so you can compare coverages and prices to find the best combination for you and your engineering operation.

Do engineers and architects have the same professional liability insurance?

Both engineers and architects need professional liability insurance to protect them from mistakes, errors, and omissions they may have in their work. Some engineers have similar risk exposure as architects, especially electrical engineers who work in construction projects. However, there are many other engineering types such as civil, chemistry, software engineers, just to name a few. These engineers are exposed to a very different risk profile from architects.

Professional liability insurance protects will provide the same coverages for errors and omissions that engineers or architects might have in their work. However, different professions will have their own nuances in their line of work, which leads to differences in their coverages. And since the risk exposure is different, the cost of professional liability insurance policies will be different for different professions.
