Legrand Electric UK, a global leader in electrical and digital building infrastructures, has transformed its warehouse operations to meet the demands of a fast-moving, data-driven construction sector.
With more than 50,000 product lines flowing through multiple sites, Legrand UK faced mounting pressure to improve visibility, reduce manual handling and support its teams more effectively.
To address these challenges, the business adopted GS1 standards and implemented a new warehouse management system. At the heart of this transformation was the Global Trade Item Number (GTIN), enabling consistent product identification and real-time inventory tracking. The result is a smarter, more connected supply chain that supports faster decision-making, stronger partner collaboration and scalable growth.
But this is not just a story about technology. It is about data, people and the power of standards to drive meaningful change. By aligning with GS1 standards, Legrand has improved operational efficiency, enhanced traceability and laid the foundations for future innovation. The company is now exploring additional identifiers such as the Global Location Number (GLN) and Global Individual Asset Identifier (GIAI), as well as QR codes powered by GS1 to deliver richer product data directly on packaging.
