Otte Sicherheits- und Elektrotechnik GmbH

What Otte Sicherheits- und Elektrotechnik GmbH does

Otte Sicherheits- und Elektrotechnik GmbH is the parent entity of the OTTE Unternehmensgruppe, a privately-held German group of three wholly-owned subsidiaries — OTTE Elektrotechnik GmbH, MAEKE Elektrotechnik GmbH (acquired in 2024, operating since 1924), and havenPLAN GmbH — headquartered in Wilhelmshaven, Lower Saxony, and operating across the North German region. The group provides electrical installation, security technology, and technical building equipment (TGA) planning services to commercial customers, public institutions (municipalities, schools, healthcare and emergency-services facilities), and private residential customers through its three segment-aligned subsidiaries.

Core service offerings cover general electrical engineering for new construction, renovation, and modernization; certified fire alarm systems (Brandmeldeanlagen) and voice alarm systems (Sprachalarmierungsanlagen) per DIN 14675; safety lighting (Sicherheitsbeleuchtung); smoke and heat extraction systems (RWA); lightning protection; access control and intrusion alarm systems; KNX-based building automation and DALI-controlled lighting; data network technology; and HOAI-compliant TGA planning across all performance phases, supported by AutoCAD-based drafting and revision services. The group's competitive position is anchored in statutory and industry certifications (DIN 14675 specialist firm, ISO 9001:2015, VdS/ZDH-ZERT, DGSV Sachverständiger, BHE Bundesverband membership, and § 6a VOB/A prequalification for public procurement).

Revenue is generated through project-based quotations across four streams: one-time electrical installation services (new construction, renovation, modernization), recurring maintenance and repair services, professional services from havenPLAN (TGA planning, expert opinions, CAD drafting), and hardware-and-installation sales of security systems. The go-to-market is direct sales-led and regionally concentrated, with no public pricing, no digital distribution channels, no disclosed revenue figures, and no external investors or funding history. The company is managed by the Otte family (Helmar Otte and Tanja Otte as geschäftsführende Gesellschafter).

Broad incumbents

• SPIE GmbH: Large European technical services provider with a substantial German operation spanning electrical installation, fire protection, security systems, and building automation; overlaps broadly with OTTE's full service offering but at national/international scale and as one capability among many.
• Hekatron Vertriebs GmbH: German specialist manufacturer of fire alarm systems and smoke detection products (part of the Swiss Securitas Group), deeply embedded in DIN 14675-compliant fire safety supply chains—comparable to OTTE's BMA-certified work as an upstream system provider serving the same certified installer ecosystem.
• Johnson Controls International plc: Global provider of building automation, fire detection, security, and HVAC controls with a strong German footprint; competes with OTTE on KNX/DALI-style automation and certified fire alarm projects, but as a large multi-national with a much broader portfolio.
• Telenot Electronic GmbH: German manufacturer of certified fire alarm, intrusion, and access control systems with VdS-recognized products; comparable in DIN 14675-aligned fire alarm expertise but positioned as a product manufacturer supported by a regional installer partner network rather than as a direct installer.
• Bosch Sicherheitssysteme GmbH: Major manufacturer and integrator of fire alarm, voice alarm, intrusion, and access control systems in Germany; overlaps with OTTE's certified fire/voice alarm and security systems work but operates as a national/international product-and-system player rather than regional installer.

Direct peers

• GEBRÜDER PETERS Elektrotechnik GmbH: Established German electrical contractor providing electrical installation, building automation, and security technology services for commercial and public-sector clients—comparable mid-market peer with similar multi-trade scope.
• Bodo Wascher Gruppe: Northern German electrical contracting and security systems group serving commercial, public, and industrial customers with electrical installation, fire alarm, and building automation services—directly comparable to OTTE Elektrotechnik in scope, regional footprint, and customer mix.
• Elomech Elektroanlagen GmbH: Mid-sized German electrical contractor delivering commercial and industrial electrical installations, security and fire alarm systems, and building technology across multiple German regions—comparable in service breadth (electrical + security) and target customer profile.
• Securitas Technology Germany (formerly Niscayah): German security systems integrator installing fire alarm, intrusion, access control, and video surveillance systems for commercial and public-sector customers—comparable service offering and customer base but operating at a substantially larger national scale than OTTE.
• Kraft + Partner Elektrotechnik GmbH: Mid-sized German electrical contractor providing installation, maintenance, and security technology services for commercial, industrial, and public-sector clients—comparable regional/mid-market electrical contractor profile to OTTE Elektrotechnik.
