Design Defect Insurance
Design Defect Insurance is a specialized liability insurance that protects professionals and companies against claims arising from faulty or inadequate design work. It is particularly crucial for architects, engineers, contractors, and other design consultants involved in construction and infrastructure projects.
Unlike general liability policies, which may exclude professional errors, Design Defect Insurance provides coverage for financial loss, bodily injury, or property damage resulting from an error in design, drawing, specification, or material selection.

Why is Design Defect Insurance Essential?
- Covers High-Value Claims: Design failures can lead to structural collapses, delays, or complete project rework—leading to multi-crore liabilities.
- Protects Reputation & Credibility: Claims due to design negligence can severely damage a professional’s or firm’s reputation.
- Mandatory in Contracts: Many government and corporate contracts require design professionals to carry such coverage.
- Legal & Financial Safety Net: Covers legal costs, settlements, and damage awards arising from alleged or proven design faults.
- Supports Risk Management: Encourages detailed quality control and professional diligence among design teams.
Important Things You Should Note

- Must be specifically requested as an endorsement or purchased under a Professional Indemnity policy.
- Often subject to a retroactive date—only claims arising from services performed after this date will be covered.
- Can be offered on a claims-made basis, meaning the policy must be active when the claim is made.
- Exclusions may apply to known defects, deliberate acts, or unauthorized design changes.

Frequently Asked Questions (FAQs)
Is Design Defect Insurance the same as Professional Indemnity Insurance?
Not exactly. Design Defect Insurance is usually a part of or extension to a Professional Indemnity (PI) policy, specifically covering design-related exposures.
Does a Contractors’ All Risk (CAR) policy cover design defects?
Not by default. Some CAR policies offer optional design defect extensions, especially for design-and-build contractors.
Who should buy Design Defect Insurance?
Architects, civil and structural engineers, MEP consultants, design-build contractors, and any professional responsible for preparing or approving designs.
Does it cover subcontracted design work?
Yes, provided the policy is extended to cover vicarious liability for outsourced or subcontracted design tasks.
Can past design work be covered?
Yes, if the policy includes retroactive cover and there’s no prior knowledge of issues before policy inception.
