What Müller Bleher Group does

Müller Bleher Group is a German family-owned technical building equipment (TGA) engineering services firm headquartered in Filderstadt, founded in 1989 by Hans Joachim Müller and Helmut Bleher. The company specializes in electrical engineering planning for buildings and industrial facilities, including power supply systems, medium and high voltage technology, lighting, conveyor technology, and renewable energy integration. It operates through five specialized subsidiaries: Müller & Bleher (electrical engineering), FAKTORLicht (lighting technology), Movetexx (conveyor and transport systems), MB Systems (BIM/digital planning and software engineering), and MB Global Engineering (international projects in healthcare, pharmaceuticals, industry, and automotive).

The group employs 251 to 500 staff across eight German locations (Filderstadt, Radolfzell, Berlin, Munich, Darmstadt, Ulm, Ohlsbach, and Essen from June 2026), with engineering work delivered through project-based professional services contracts. Technology stack includes BIM (Building Information Modeling), Revit, CAD, and PowerFactory for medium and high voltage grid calculations, alongside proprietary specialization in grounding systems, short-circuit current management, and scalable EV charging infrastructure design via busbar systems. Pricing is project-based with customized quotes; no public rate cards or tiered pricing exist.

Customers span healthcare facilities, industrial and pharmaceutical plants, commercial real estate, heritage/religious buildings, and renewable energy projects. Notable engagements include the Roonstrasse Synagogue renovation in Cologne (alongside Manuel Herz Architekten, targeted completion 2029/2030) and the KARLA administrative and educational center in Karlsruhe district. Leadership transitioned from founding families to a mix of family principals and professional management in 2026, with Marc Betz joining the MB Holding board and Christopher Gertler taking over the Filderstadt entity; ownership remains with the Müller and Bleher families under the Müller & Bleher Holding GmbH & Co. KG umbrella. No private equity, venture capital, or public listing is evident.

• ATP architects engineers: Integrated architecture and engineering firm with German operations and strong MEP/TGA planning capabilities. Comparable as a multi-disciplinary design firm combining architecture, structural, and building services engineering for complex institutional and commercial projects.

Broad incumbents

• TÜV SÜD: Large German testing, certification, and engineering services conglomerate. Overlaps with Müller Bleher's power systems, grounding, and energization-adjacent expertise but operates at vastly larger scale across many sectors beyond TGA.
• Sweco: European engineering consultancy with significant German presence following Grontmij acquisition. Comparable business model (MEP, electrical, and infrastructure engineering) but with pan-European scale and broader service portfolio than Müller Bleher.
• WSP in Deutschland: Global engineering consultancy with German offices offering MEP and building services engineering. Competes for similar institutional and commercial projects but with much larger bench and global delivery capability.
• Ramboll Deutschland: Global engineering consultancy with German operations covering buildings, energy, and infrastructure. Overlaps with Müller Bleher's TGA and energy systems planning but operates at vastly larger scale and broader geographic scope.

Emerging players

• Steinigeweg Ingenieure: Smaller German engineering office specializing in electrical and information technology building services. Comparable mid-sized competitor focusing on similar TGA planning niches as Müller Bleher's core electrical engineering business.
