Our UK & Ireland Network
As a Phenna Group company, CGL is part of a UK & Ireland network of specialist testing, inspection, certification and compliance (TICC) businesses.
While CGL specialises in geotechnical and geoenvironmental consultancy, many of the projects we support require expertise from multiple technical disciplines. Through Phenna Group, we can connect clients with complementary specialists across infrastructure, the built environment, laboratories, environmental services, certification and compliance.
From specialist testing and site investigation to environmental consultancy, building compliance and certification, our wider network brings together technical expertise from across a diverse range of sectors. This enables clients to access the right capabilities for every stage of their project through a trusted group of specialist businesses.
