Key takeaways

The Architects & Engineers (A&E) Professional Liability (PL) marketplace in 2026 has been broadly described as stable for favorable risks, driven by continued competition as a result of ample capacity, despite carrier consolidation.
  • A&E professional liability remains stable for favorable risks, with competition supporting flat renewals.
  • A&E firms with a high-risk profile face greater underwriting scrutiny, deductible pressure and potential rate increases.
  • Adverse claim severity trends, social inflation and longer claim resolution times remain key market concerns.
  • Auto and umbrella lines face the most pressure as bodily injury claims and large verdicts continue to rise.

The Architects & Engineers insurance market is entering 2027 in a stable but increasingly selective environment. While competition and available capacity continue to create opportunities across several coverage lines, auto liability remains challenged by rising claim severity, social inflation and the ongoing threat of large verdicts. Professional liability conditions are similarly divided between favorable risks and more challenging accounts with higher-risk project profiles, adverse claims histories or complex operations. Renewal outcomes can range from flat to 15% increases depending on exposure characteristics and line of coverage.

Although overall pricing has remained relatively stable, insurers continue to express concerns that rates may not adequately reflect long-term loss trends. Carriers report increasing claims severity, longer claim resolution periods and growing settlement costs. Insurers are also paying closer attention to emerging exposures involving artificial intelligence, climate change and economic uncertainty.
