Here are the top E&O insurance companies for your consideration.

What factors affect the E&O insurance cost?

The above estimates give you an idea of what companies may anticipate spending on average for E&O coverage. As we already said, the real cost of E&O insurance varies. The value of your policy depends on certain variables

.You must understand how these variables may affect your rates to gain control over your premium costs. That said, the following are some variables that may impact your premium:


Insurers will initially assess your industry before setting rates. Your industry will determine two essential factors: the likelihood of claims and the possible cost of resolving them. In most cases, professionals like those in medicine, law, finance, architecture, and engineering tend to pay more for E&O insurance. 

Professionals in this field pay more for errors and omissions insurance because their mistakes or omissions usually have devastating consequences. For instance, a doctor’s mistake may lead to the loss of lives, attracting serious lawsuits. 


The cost of E&O insurance varies depending on the location and state where your company operates. Some US states have minimum E&O coverage requirements for particular sectors. As such, firms operating in these jurisdictions may have higher insurance premiums. 

In Idaho, for example, attorneys must have legal professional liability insurance, and in 23 other states, law firms must inform clients if they have E&O coverage. Similarly, most states require doctors to carry minimum malpractice insurance limits.

Also, firms in densely populated areas like New York, San Francisco, and Los Angeles frequently have higher rates. 

Coverage limit

The limit of an insurance policy is the maximum amount your insurer will pay out for claims. Generally speaking, the more coverage you need, the higher your premium costs. Most companies usually require a coverage limit of about $1 million. This coverage limit should cover most risks, but some companies may require larger limits due to their risk profile. 

You must grasp how coverage limitations operate while seeking errors & omissions insurance so that you don’t end up paying so much out of pocket if an incident occurs. 

E&O insurance usually has two kinds of limits: occurrence and aggregate.

  • Occurrence limit: Occurrence limits are calculated per incident. It implies the amount your insurer is willing to pay for every incident, irrespective of the circumstances. 
  • Aggregate Limit: Aggregate limits are calculated for the entire period of the policy. It refers to the maximum amount your insurer will pay out during the course of the policy.

Annual sales

When giving you quotes for E&O insurance, your insurer will want to see your annual income. The more your company earns, the more you will pay for E&O insurance. The rationale behind this is that lucrative businesses are more prone to litigation. And if they lose or have to settle out of court, they usually have to pay more than smaller corporations with less income.

Firm size

Like revenue, the firm’s size affects the cost of E&O insurance. Company size here refers to the number of staff that a company has. 

A company with a large workforce has more hands that can make mistakes. Therefore, the more staff you have, the more you will pay for your E&O insurance premium.

Years of experience

Experts and mature businesses should receive lower rates. This is because professionals tend to make fewer mistakes as they spend more years at their jobs. 

Past claims

Insurers will want to know how many E&O-related lawsuits have been brought against your company. A history with many claims could mean your staff members are reckless at their jobs, so you may have to pay more. However, a history of fewer claims could mean less premium costs.

Deductible types 

Your E&O premium is determined by the deductible you choose. Usually, a high deductible means a cheaper premium. A deductible is the money you must pay before your insurer pays for a covered peril. Most E&O insurers provide two deductible options:

  • First-Dollar-Defense (FD) Deductible: This deductible is only required for paid claims. In other words, the corporation is not required to pay until the issue is resolved.
  • Defense-And-Loss (DL) Deductible: Includes defense expenses and paid claims.

If you are sued for E&O, your insurer will usually engage a lawyer to defend you. The cost of hiring the defense counsel starts piling up as soon as the claim is filed. The lawyer must create a file, research, prepare the case, and defend the client.

 If you have an FD deductible, you will not pay anything until the case is resolved. However, A DL deductible requires the corporation to pay a portion of legal bills even if the action is dismissed.

An FD deductible generally costs more than a DL deductible.

How to obtain cheap E&O insurance

By learning to control some of the variables that affect E&O insurance, you may be able to get lower quotes. Most people choose lower coverage limits and adjust their deductible. While this will work, you might pay more in the event of a covered peril. However, this isn’t the only way to save money on your premium. 

The following are some of the ways you might obtain cheap E&O insurance quotes:

Always compare several quotes

First of all, always shop around with a few companies or work with a top broker like CoverWallet or ez.insure or commercialinsurance.net to get and compare several quotes to select the cheapest one for you. Different insurance companies assess risks differently and they all have their own business strategies to be in favor for or not in favor for particular industries, that impact their pricing strategies for your business. Getting a fast online quote from Thimble is another good way, even just to see the ballpark of your E&O insurance cost.

Pay your premiums in full

You might choose to pay your insurance premiums annually rather than monthly. While making smaller monthly payments saves money upfront, paying a yearly premium saves money by up to 25% in the long run.

Maintain coverage

Some companies prefer to obtain professional liability insurance at the outset of a project and cancel it at the end since it is cheaper. However, this method may cost you dearly. Your professional liability insurance coverage must be active if you want to receive its full benefits. If you want to avoid paying for professional liability litigation, you need ongoing coverage. 

Reduce hazards 

Regrettably, insurance claims raise premiums. Less risk means fewer claims and less money spent on premiums. Sadly, risk is unavoidable. If it were possible to remove risks totally, insurance companies would not be in business. 

Insurance firms do business by offering coverage to mitigate risk. But you may not be aware that they often reward policyholders that strive to reduce risk.

Errors and omissions (professional liability) coverage may be expensive, but risk management can help you lower the cost. A strong E&O risk management plan may include:

  • Having detailed client contracts
  • Keeping good client relationship
  • Attending to client complaints and resolving them quickly
  • Checking (and rechecking!) your work as many times as possible
  • Engaging cybersecurity tools to decrease risks

Contractual risk transfer

Another way to reduce the risk of doing business is to transfer your risks to someone else or another company. You can engage the services of independent contractors for certain jobs. That way, they will be responsible for whatever claims occur while offering their services.

However, while outsourcing, be sure they are covered and seek to be included as an extra insured. So, you’re not exposed if anything occurs. Instead of depending on your coverage, you may use theirs if an incident occurs.

Avoid engaging uninsured subcontractors to reduce your risk. If an uninsured contractor is hurt while working for you, you may be liable for claims. Remember that claims affect your policy’s cost, so make sure subcontractors have their own. They can’t depend on you.

What is E&O Insurance?

E&O insurance, or also called professional liability insurance, protects you against the claims of negligence, your failure of delivering professional services, and professional mistakes made against you by your clients.

If you are in the business to deliver professional services to your clients, you will need to have an E&O insurance policy to protect you in case your clients decide to sue you. Even you did not make any mistake, when your clients sue you, you still need the E&O policy to pay for any associated legal costs and attorney fees, which can be expensive.

E&O insurance is also called malpractice insurance for healthcare and legal professionals. They are basically the same.

What does E&O Insurance Cover?

E&O insurance covers negligence, mistakes, omissions, and misinterpretations.

For example, if you are a real estate agent, you advised a client to buy a home at a price based on your analysis of a set of 8 recent sales in that area. You omitted another 5 recent sales in the area with much lower prices. This resulted in a higher recommended price than it should have been. After discovering the omissions, your client can sue you. Your E&O insurance policy would help cover all legal fees, defense attorney costs, and settlements as well. Without an E&O insurance policy, you would have to pay everything out of your pocket.

Who needs E&O insurance?

Anyone can sue any company in today’s world. Sadly, companies that operate on people or provide advice/consultation services are more liable for suing. Therefore, if clients can sue your company for professional errors, you should consider getting this policy. 

The following are some professional service companies that must have Errors and Omissions Insurance:

  • Architects
  • Bankers
  • Doctors
  • Financial advisors  
  • Lawyers
  • Nurses

Basically, any firm that charges for services or advice may be sued. A consumer might easily accuse you of failing to meet your professional commitments. Then you’re in court battling for your company’s image and cash.

The good thing about E&O insurance is that you can purchase the policy with ease through the internet. This kind of insurance is available from most major insurance firms, and many of them provide online quotes. Here are our recommendations for the best E&O insurance companies to make things easy for you.

Last Thoughts

Society has become increasingly litigious. You don’t even have to have made any mistakes for a client to drag you off to court, which is stressful and unsettling. Protect yourself by getting at least a basic E&O insurance policy. That way, someone sues for a frivolous reason, your court costs will be covered, and you can rest easy.
