Professional Liability for Design Professionals: Why It's Unique

Why A&E Professional Liability Is Unique

  • No ISO Form: There is no standard ISO form for A&E PL policies. Each insurer writes their own policy language, resulting in wide variations in coverage.

  • Real Exposure: Claims for design errors, documentation mistakes, code violations, delays, and jobsite injuries are common. Over 50% of A&Es experience a claim in their career.

  • Long-Tail Nature: The average claim occurs two or more years after project completion. Firms must be able to reference old project documentation to support their case. Retroactive continuity is critical.

Key Coverage Components

  • Limits of Liability: Usually written per claim/aggregate (e.g., $1M/$1M, $1M/$2M, $2M/$2M, $5M/$5M). Selection depends on firm size, project type, and client requirements.

  • Deductibles: Can be per claim or aggregate. Smaller firms may qualify for First-Dollar Defense, delaying out-of-pocket legal fees until a settlement or judgment.

  • Core Coverage: Professional services, claims defense, pre-claims assistance.

  • Extended Coverage: Optional endorsements like:

    • Specific Job Excess (SJX)

    • Cyber liability

    • Pollution

    • Contract review services

Price vs. Value

Many firms compare policies based solely on price. However, broader coverage often means higher upfront cost—but can save significantly in a claim. Restrictive policies may exclude key risks or carry high deductibles.

There are many ways to reduce to cost of insurance without cutting coverage that we have outlined in our 7 Ways to Save resource.

How Is the Policy Priced?

Insurers consider multiple factors:

  1. Discipline (architecture vs. civil vs. MEP)

  2. Gross annual billings

  3. Project types (e.g., schools, commercial, custom homes)

  4. Claims experience:

    • History

    • Frequency

    • Severity

  5. Risk management practices (e.g., contract review, education, project screening)

  6. Location, firm experience, scope of services

New PL policies typically cost less because they cover fewer past exposures. Over time, premiums may rise due to inflation, exposure growth, or market conditions. Discounts may apply for:

  • No claims history

  • Use of standard contracts

  • Risk management participation
