Where is Willis Towers Watson headquartered?

Willis Towers Watson's headquarters is in London, UK, with the public headquarters address listed as 51 Lime Street, London EC3M 7DQ, United Kingdom. The headquarters is the best starting point for board, executive, investor-relations, corporate, finance, legal, risk, and enterprise-technology mapping.

For sales planning, headquarters does not always equal the largest technology or operations hub. It is still the highest-confidence anchor for executive alignment and account ownership.

Willis Towers Watson's footprint includes London, UK, New York, NY, Chicago, IL, Philadelphia, PA, Dublin, Ireland, Mumbai, India. These hubs reflect a mix of corporate, client-facing, operations, technology, branch, advisory, and international roles depending on the company.

When planning field activity, treat the footprint as directional. Verify current office status and team ownership before scheduling executive briefings, local events, or onsite implementation work.

Territory planning should separate headquarters executives, technology and operations hubs, regional business leaders, and client-facing market teams. The most productive events are usually near headquarters or a large business/technology hub, while branch or field markets are better for localized adoption and relationship-building.

For account-based marketing, map personas to offices: CIO/CISO and operations for platform work, business-line leaders for workflow outcomes, finance/procurement for budget, and risk/compliance for approval.
