Professional liability (E&O) insurance

Professional liability insurance, also called errors and omissions insurance (E&O insurance) or professional indemnity insurance, costs an average of $197 per month, or $2,365 annually, for engineers.

This policy covers the cost of client lawsuits over claims that your work was unsatisfactory, negligent, late, or never completed.

For instance, if a structural design fails or a project delay costs a client money, a professional liability insurance policy would cover your legal defense costs, settlement, and other financial losses.

Below is the average professional liability policy for engineers who buy from Insureon:

Insurance premium: $197 per month
Policy limits: $1 million per occurrence; $1 million aggregate
Deductible: $2,500

Several factors influence the cost of professional liability insurance, including the type and size of business you have, your claims history, the types of projects you take on, location, and the policy limits and deductible you select.

As with other types of insurance, you can save money on professional liability coverage by choosing lower limits or a higher deductible.

Reducing your risks also helps you avoid claims and keep your premium low. This includes clear communication with clients and thorough documentation of all communications and agreements.

General liability insurance

Engineers pay an average of $39 per month, or $472 annually, for general liability insurance. This policy is sometimes called public liability insurance.

General liability insurance covers common third-party risks at engineering businesses, such as a client who slips on a wet floor at your office and suffers a bodily injury, or accidental damage to a client's property.

For example, if you drop and break a client's smartphone while they're showing you a design they like, general liability insurance coverage would pay for the repair costs or legal fees if the client sues over property damage.

It also helps pay for attorney's fees and other legal expenses if someone sues your business over copyright infringement or other advertising injuries, including defamation.

Below is the average general liability policy for engineers who buy from Insureon:

Insurance premium: $39 per month
Policy limits: $1 million per occurrence; $2 million aggregate

The per-occurrence limit is the maximum your insurer will pay for a single covered incident, while the aggregate limit is the most the insurer will pay for all claims during the policy period, typically one year.

General liability insurance costs depend on factors such as the coverage limits and deductible you choose, the types of professional services you offer (i.e., mechanical engineering, structural engineering, civil engineering, etc.), your business income, and any additional insured endorsements you select.

Business owner’s policy

Engineering businesses pay an average of $61 per month, or $731 annually, for a business owner’s policy.

A business owner's policy, or BOP, bundles general liability coverage with commercial property insurance to cover both third-party risks and your business property. It typically costs less than purchasing each policy separately.

A BOP protects against customer injuries, property damage, and vandalism, along with damage to your engineering equipment. Because of its increased coverage and affordability, it’s the policy most often recommended by Insureon’s agents.

This is the average BOP for engineers who buy from Insureon:

Insurance premium: $61 per month
Policy limits: $1 million per occurrence; $2 million aggregate
Deductible: $500

Small, low-risk engineering companies are often eligible for a business owner's policy.

Engineering business owners may see higher costs if they choose to add endorsements to their policy. Insurance endorsements, such as business interruption insurance or equipment breakdown coverage, are often recommended to help avoid financial losses if a fire or power outage forces your business operations to cease for an extended period of time.

The cost of a business owner's policy is based on a number of factors, including the value of your business property, where you are located, types of projects you take on, the number of employees you have, and your specialty.

Workers’ compensation insurance

The average cost of workers’ compensation insurance is $50 per month, or $596 annually, for engineering companies.

This policy covers medical expenses and lost wages related to employee injuries. It usually includes employer's liability insurance to protect against lawsuits from injured workers.

Businesses with employees typically must purchase workers' comp to comply with state requirements and avoid penalties. For example, all engineering businesses in California, Pennsylvania, and New York must carry workers' comp if they have one or more employees. Florida businesses need coverage when they have four or more employees, and coverage is optional in Texas.

Since health insurance plans can deny claims for injuries related to your job, workers' comp coverage is also recommended for independent contractors as a financial safety net and for peace of mind.

The cost of workers' comp depends on several factors, primarily the number of employees you have and their occupational risks. You can save money on workers' comp coverage by classifying your employees correctly and implementing a risk management plan to avoid work-related injuries and subsequent claims.

Commercial auto insurance

Engineers pay an average of $231 per month, or $2,766 annually, for commercial auto insurance.

This type of insurance pays for legal costs and medical bills if your company vehicle injures someone or damages their property in an accident. It can also cover vehicle theft, vandalism, and weather damage.

Most states require commercial auto insurance for vehicles owned by an engineering business. For personal, rented, and leased vehicles used for work purposes, look to hired and non-owned auto insurance (HNOA) instead.

The cost of commercial auto insurance depends on several factors, including your policy limits, additional coverage options you choose (e.g., additional insured endorsements), the number and value of your vehicles, and the driving records of anyone permitted to drive.

Cyber insurance

Engineering firms spend an average of $84 per month, or $1,004 annually, on cyber insurance. This policy is also called cyber liability insurance or cybersecurity insurance.

Cyber insurance helps your engineering business recover financially after a cyberattack or data breach. It can cover data breach investigations, cyber extortion payments, and costs related to complying with your state's data breach laws.

A cyber liability insurance policy is especially crucial for engineering companies that store sensitive client information, such as credit card numbers, Social Security numbers, and email addresses.

The cost of cyber insurance and the coverage you need depend on the amount of sensitive information you handle at your engineering firm.

How are engineer insurance costs calculated?

Engineer business insurance coverage costs are determined by several factors. While underwriting your policy, insurance companies will consider the following when calculating insurance rates:

  • Type of engineering specialty: Engineering companies may see elevated premiums, depending on their niche specialty. For example, structural and civil engineers often face greater professional liability risks because design errors can have significant consequences for projects, so they would expect to see higher premiums.
  • Business property and equipment: Engineers that operate with higher-value tools or equipment, such as surveying equipment or testing tools, are likely to see more expensive premiums. Also, any items that are frequently used could cost more to insure than items which are used less often.
  • Annual revenue: The more your engineering business makes in a year and the more you pay your employees or subcontractors, the higher your premium will cost. That’s because increased revenue and payroll often indicate larger projects, more clients, and greater exposure to possible claims.
  • Location: If your engineering business operates in an area that is more prone to natural disasters, increased foot traffic, or high crime rates, you may have to pay higher insurance costs than an engineer located in an area where these factors are less present. Also, your state's litigation trends and local regulations can affect costs.
  • Years of experience: Engineering firms and professionals with an established track record may be eligible for lower insurance rates than newer businesses with limited operating history.
  • Type of projects: Insurance companies take into account the types of projects you take on, including their complexity and size. An engineering business that works on high-risk, larger, or more specialized projects may see increased premiums compared to one that only takes on smaller and less riskier projects.
  • Claims history: An engineering firm with a lengthy list of previous insurance claims will likely pay more for insurance than one with no claims history.
  • Types of coverage: For professional liability coverage, the type of policy you choose can influence your premium. Most professional liability policies for engineers are written on a claims-made basis, which generally start with lower premiums that then increase during the first few years of continuous coverage. While occurrence-based policies are less common for professional liability insurance, they may be available for certain other types of business insurance.
  • Number of employees: The more employees and subcontractors your engineering business has, the greater the potential for mistakes or errors, property damage, and liability claims.
  • Coverage limits and deductibles: Engineering companies with higher coverage limits and lower deductibles on their insurance policies will typically increase their premium costs, while lower limits and a higher deductible can help keep their rates lower.
