What is Professional Indemnity Insurance?

Professional Indemnity Insurance is specific insurance designed for professionals offering consultancy or services to third-party clients. It works as a protection for you and your business against legal claims made by the clients.

The legal claim or cost can occur when the client endures some damage due to mistakes, breaches, omissions, or errors in the work by the organization.

Some of the crucial claim coverage under Engineer/Architect’s Professional Liability Insurance are:

  • If the constructed property does not comply with the local laws or building codes, causing rectification works to fit the standards.
  • Any negligence in design leads to cracks or damage, causing repair charges.
  • When the engineer specifies the wrong color tiles in the design, leading to a reduction in property value.
  • If the engineer specifies slippery tiles for a wet area, causing falls or injuries.

Why do Architects and Engineers need PI Insurance?

When working on a project, professionals such as architects and engineers become entitled to professional liability for delivering the best services and claiming responsibility for any loss or injury caused due to their work. The risks of carrying out business and offering such services are big, and even a small mistake or lack of caution can bring chaos and ruin an architect’s or engineer’s career and business.

Thus, it becomes essential for architects and engineers to have professional indemnity insurance.

Besides this, it is crucial to protect the interests of all the workers working with you as they are always prone to getting into accidents on site. Injuries to your team on site are covered by workers’ compensation or employer’s liability insurance, not by professional indemnity insurance.

Claims-Made or Occurrence: Know the Difference

Most professional indemnity policies are claims-made. This means the policy covers a claim only if it is made while the policy is active, even if the work was done years earlier. Some policies are occurrence-based, which cover work done during the policy period, whenever the claim is made.

FeatureClaims-MadeOccurrence
When the claim must be madeWhile the policy is in forceAny time, if the work was done while the policy was in force
Common for professionalsYes, most PI policiesRare for PI

Check the retroactive date on your policy. It is the earliest date for work that is covered. If you change insurers, make sure the new policy keeps the same retroactive date, or you may lose cover for old work.

Is PI Insurance a Legal Requirement?

It depends on your country and your profession. In Australia, registered architects must hold professional indemnity insurance in most states and territories as a condition of registration. Engineers who work under the Queensland registration scheme (RPEQ) also need adequate PI cover. In the United States, PI insurance is not always required by law, but it is often required by a client contract or by a licensing board. Check the rules for your state or territory and read every client contract before you sign it.

How Much Cover Do You Need?

There is no one right amount. Consider these points.

  • Project size. Larger projects bring bigger claims. A school or a hospital project can lead to a claim many times larger than a small house project.
  • Contract terms. Many clients ask for a minimum limit, such as $1 million, $5 million, or $10 million. Check the contract.
  • Your risk. Firms that do high-risk work, such as structural design, often need higher limits.
  • Your excess. A higher excess (deductible) lowers your premium, but you pay more if a claim comes in. Keep the excess at an amount you can afford.
  • Run-off cover. If you retire or close the firm, keep run-off cover for several years, as claims can arrive long after the work ends.

What to Do When a Claim Arrives

  1. Do not admit fault or offer to pay. Let the insurer handle it.
  2. Tell your insurer at once, in writing. Most policies require prompt notice.
  3. Send the insurer the claim letter and all papers about the project.
  4. Keep a record of every call and email about the claim.
  5. Do not change or delete project files. Keep all drawings, emails, and notes.

Late notice can let the insurer refuse the claim. Tell your broker or insurer as soon as you hear that a client is unhappy, even before a formal claim is made. Many policies cover early notice of a situation that may become a claim.
