Contractor’s pollution liability (CPL)
The insurance market for pollution liability exposures should remain favorable for contractors in 2026. With ample capacity and relatively low retentions, contractors seeking either project-specific or practice policies will find coverage readily available. A robust marketplace, including new players that entered in 2025, is driving competitive pricing and broad terms and conditions for contractor’s pollution liability placements.
While the pursuit of CPL placements is often driven by contractual requirements, underlying risks are primarily shaped by evolving environmental regulations, which have significantly impacted the insurance landscape. One area undergoing continual change involves laws related to per- and polyfluoroalkyl substances (PFAS), commonly referred to as “forever chemicals.” Currently, most CPL insurers provide coverage for PFAS, but pollution policies contain important nuances. For this reason, partnering with brokers that have environmental expertise is essential to help contractors navigate the excess and surplus lines market, where CPL coverage is typically written.
Common losses stem from pollution conditions that are caused or exacerbated by a contractor, such as a broken pipe that releases petroleum or stockpiling contaminated soils on a site during construction. Completed operations claims for mold can be costly.
Risk mitigation steps that contractors should consider include:
- Understanding environmental, health, and safety (EHS) regulations. A solid understanding of EHS is an overlooked aspect of construction operations.
- Performing strong due diligence. Environmental risk is important for owners and developers as well as contractors. Historical site pollution can be identified through environmental site assessments, which lenders generally require for later phases of construction. Contractors can commission these early on to minimize unknown conditions that might trigger claims later.
- Assessing pollution coverage and how it applies. Owners and developers should trust but verify that contractors have adequate pollution coverage. A certificate of insurance will provide evidence of coverage but not how it may apply to the project.
- Seeking complementary coverage where available. CPL coverage by itself will not meet all the pollution risk financing needs on a given project. Site pollution coverage dovetails with CPL policies to provide more comprehensive protection for cleanup and remediation, especially for sites with known or potential historical contamination.
