What elektro beyer & blank haustechnik does

Elektro Beyer & Blank Haustechnik GmbH is a family-owned German electrical contracting firm headquartered in Schwielowsee OT Geltow, Brandenburg, serving the Berlin, Potsdam, and Brandenburg metropolitan area. Founded in 1961 by Elektromeister Wolfgang Beyer, the company has operated continuously for more than 60 years through multiple ownership and structural transitions, including incorporation as a GmbH in 1999 and a 2005 merger with Elektro Blank Potsdam. Since 2019, Christian Schwarz has been sole shareholder and authorized managing director (Geschäftsführer). The firm operates as a registered Innungsfachbetrieb under the E-Handwerk trade guild and employs 13 staff, including two KNX-certified master electricians, six electrical installers, three helpers, and two apprentices.

The company's core competency is KNX building system technology (EIB/KNX bus systems), with more than 20 years of specialization in this standardized building automation protocol. It delivers integrated building automation projects that unify KNX, LCN, homematic, GIRA one, and Busch-Jaeger free@home platforms into single systems spanning intercoms, lighting, shading, multiroom audio, intrusion detection, heating regulation, video surveillance, wallbox (EV charging) integration, and photovoltaic management. Supporting service lines include Elektroinstallation (general electrical installation), Baustrom (construction-site and event power), IT network cabling and telecommunications (passive/active network infrastructure, Auerswald phone systems, AVM FRITZ! networking), antenna and broadband community antenna systems, fire protection (smoke/heat extraction), PV-Anlagen, and electrical infrastructure for large events. The firm uses DDS-CAD for project planning and operates a functional sample wall at its premises for client demonstration and pre-installation testing.

Revenue is generated entirely through project-based professional services contracts with no public pricing and no recurring or subscription component. The customer base spans residential households, small commercial offices, large institutional clients (notable references include Nikolaikirche Potsdam, Potsdam Museum/Altes Rathaus, MABB Berlin-Brandenburg, Spielbank Potsdam, ADAC Fahrsicherheitszentrum Linthe, Geschwister-Scholl Gesamtschule, and Stadthaus Potsdam), and luxury residential villas. Customer acquisition runs through direct project inquiries via the company website, qualified leads routed through the GIRA Home Assistant configurator (the firm is a certified GIRA System Integrator), and the official KNX partner directory. Distribution is strictly regional within the Berlin/Potsdam/Brandenburg catchment, and the business carries no external institutional investors, no subsidiaries, and no recorded funding activity.

Broad incumbents

• Schneider Electric: Global broad-line building automation and electrical solutions provider whose KNX-compatible systems and EcoStruxure platform compete for the same institutional and commercial automation projects that Elektro Beyer & Blank serves at a regional level.
• ABB: Major building-automation and electrification incumbent whose KNX ecosystem presence and large-scale integration capabilities overlap with the institutional building automation segment Elektro Beyer & Blank targets.
• Siemens Building Technologies: Large building automation and smart infrastructure provider competing for the same museum, government, and commercial automation RFPs in Germany through its Desigo and KNX-compatible portfolios.
• Jung ( Albrecht Jung GmbH & Co. KG): German manufacturer of KNX-compatible switches, sensors, and building automation systems, serving as both a technology supplier to integrators like Elektro Beyer & Blank and a brand competing for the same end-customers in the German market.
• Gira Giersiepen GmbH: Core technology partner of Elektro Beyer & Blank (GIRA System Integrator / Smart Home Partner) and a leading German KNX manufacturer; competes indirectly by referring installation work to certified integrators but also sells KNX products to competing installers.
• Busch-Jaeger (ABB): Manufacturer of free@home and KNX-compatible building automation systems used by Elektro Beyer & Blank; broader German smart-home and building automation presence makes it a relevant comparable in the smart-building ecosystem.

Others

• E-Plan / EPLAN: Engineering software vendor providing electrical CAD/planning tools used by German electrical contractors; comparable in the planning/design software ecosystem supporting KNX project work, where DDS-CAD is a competing tool.
• AVM (FRITZ!): Technology partner of Elektro Beyer & Blank (AVM E-Premium Partner) and a major German networking/communications vendor; comparable as an adjacent enabling technology provider rather than direct competitor, but referenced because of the partnership overlap.

Regional players

• Elektro Hörburger: Regional German electrical contractor with KNX and building-automation expertise; comparable as a similarly sized specialist contractor operating in a defined regional market with overlapping institutional and residential customer segments.

Direct peers

• Ottenbruch Elektrotechnik: German KNX-certified electrical contractor of comparable scale delivering KNX building automation, electrical installation, and smart-home integration services to residential and commercial customers — a closely comparable regional specialist peer.
