Horst Busch Group

What Horst Busch Group does

Horst Busch Group is a family-owned electrical engineering services group headquartered in Hamburg-Harburg, Germany, founded in 1973 and now in its third generation of family ownership under managing directors Oliver Seib, Markus Seib, and Benjamin Mühlberg. The group operates through six wholly-owned subsidiaries spanning electrical installation (Elektro-Technik), alarm and security technology (Alarm- und Sicherheitstechnik, including the acquired norsitec brand in Kiel), expert witness and consulting (Pelka + Seib), large-scale electrical projects (Elektro-Großprojekte), IT services (Viridicon Primus), and personnel placement for electricians (Planung, Personal & Technik).

The company delivers project-based electrical, safety, IT, and workforce services to industrial, commercial, public-sector, and residential clients across Hamburg and northern Germany, with particular specialization in explosion-protected installations for petrochemical and oil-industry customers, VdS-certified fire and intrusion alarm systems, EV charging infrastructure with intelligent load management (including MAHLE centralized systems), and smart-building/IoT integration. Revenue is generated through quote-based project contracts, multi-year framework agreements with permanent on-site personnel, and temporary/permanent electrician placement, with no public pricing, subscription, or self-serve channels. Customer engagements range from small service calls to projects of €370,000+ (aviation paint booth installation) and higher six-figure contracts (oil-industry central alarm network across 15 sites), distributed across petrochemistry, logistics, aviation, healthcare, public-sector, real estate, food manufacturing, and port/maritime end markets.
