WIEDEMANN-Gruppe

What WIEDEMANN-Gruppe does

WIEDEMANN-Gruppe is a privately held, family-owned German technical wholesale group specializing in sanitary, heating, ventilation, and electrical (SHK-E) building technology products. Headquartered in Sarstedt, the group operates through eight legal entities (WIEDEMANN Sarstedt KG, WIEDEMANN Burg GmbH, WIEDEMANN Siek GmbH, WIEDEMANN Berlin KG, WIEDEMANN Planung und Beratung GmbH, WIEDEMANN Gebäudetechnik KG, LSH, and the holding WIEDEMANN Dienstleistung und Verwaltung GmbH), serving professional SHK craftsmen, installers, industrial customers, hospitals, hotels, and retail chains across northern Germany and Berlin via approximately 70 branch locations and roughly 1,200 employees.

The core distribution model combines direct branch sales, pickup warehouse service, and B2B e-commerce through shop.wiedemann.de, supplemented by the AI-powered "Teilefinder" (photo-based parts identification), 3D-Badplaner bathroom planner, and E-Procurement interfaces. WIEDEMANN distributes both exclusive proprietary brands (SCALIDO, sanibel, comfort by sanibel, 4YOU, ARTO, ACTIS) and premium third-party brands, with custom air duct manufacturing and pipe processing capabilities at the Burg facility (2,400 sqm). The company is a member of the HBG alliance of six SHK wholesalers, providing access to over 270 pickup locations, 100,000+ warehouse articles, and the unified badpunkt bathroom showroom brand (120+ locations nationwide). LSH, founded 1986, supports 350+ trade members with cooperative services and digital tools.

Revenue mechanics are transaction-based B2B wholesale with quote-driven pricing available only to registered trade customers via the HBG customer card system. The company monetizes through hardware sales across all eight trade categories (sanitary, heating, ventilation, electrical, pipes, installation, tools), supplemented by professional services including air duct fabrication, pipe processing, planning and consulting, and end-consumer bathroom design. As a third-generation family enterprise preparing for a fourth-generation transition (Louisa Wiedemann joined in 2021), WIEDEMANN has pursued steady geographic and brand consolidation, completing the acquisitions of WESEMEYER (2003), Peter HELLMICH KG (2018), and Nupnau GmbH (2025), and unifying all operating subsidiaries under the WIEDEMANN master brand in 2025.
