WYG Group

What WYG Group does

WYG Group operates as part of the Tetra Tech Europe platform — a technical, engineering, and environmental consultancy serving public and private sector clients across the UK, Ireland, and the Netherlands. The group delivers professional services spanning architecture and design, asset management, engineering, environment, ground engineering, health, safety and compliance, laboratory services, planning, project and cost management, and strategic advisory. Its service delivery is organized around seven vertical sectors: buildings and land development, defence, energy, government services, international development, transport, and water.

The group's underlying methodology is the proprietary "Leading with Science®" approach, which combines scientific expertise with engineering capabilities to produce resilient, multidisciplinary solutions. Specialist sub-brands — Hoare Lea and NDY for advanced building services, Coffey Geotechnics for geotechnical work, Carron + Walsh for project and cost management, and Tetra Tech International Development for international development programs — operate as integrated capabilities within the platform.

Commercially, the group generates revenue through professional consulting and engineering engagements delivered on a direct, project-based basis to enterprise and government buyers. Go-to-market is enterprise field sales, supplemented by content marketing (TetraVerse newsletter, expert interviews, project showcases), social channels (LinkedIn, Instagram, Facebook), and event participation such as UKREiiF. The European operation employs more than 6,000 staff and is anchored by a London regional headquarters with offices in Dublin and Amsterdam, drawing on the financial and technical resources of parent Tetra Tech, Inc., which reports $5bn in global annual revenue and 25,000+ employees across 500 offices worldwide.
