Rathmann Elektrobau

What Rathmann Elektrobau does

Rathmann Elektrobau GmbH is a privately held German electrical contracting company headquartered at Hauptstraße 71a in Heinsen, Lower Saxony. It delivers installation, automation, and maintenance services to residential, commercial, and industrial customers primarily across the Weser-Leine region — with dedicated service-area coverage in Höxter, Holzminden, Hameln, Göttingen, and Bad Pyrmont. The company's go-to-market is direct field service: technicians are dispatched on-site to homeowner and SMB/industrial clients, with sales supported through a service-line website (rathmann-elektro.de) and organic social channels (Facebook, Instagram). No public pricing model or contract terms are disclosed.

The service portfolio is broad and explicitly positioned as 'Alles aus einer Hand' (everything from a single source). Core electrical work covers residential and industrial/commercial installation, renovation, and the E-Check safety inspection. Adjacent technical categories include fiber optic network infrastructure, switchgear and control systems, industrial automation, IT networks, multimedia systems, and street lighting. Newer growth-aligned categories comprise Smart Home, E-Mobility charging installation, and Renewable Energy (solar and battery storage). Safety offerings include fire alarm (Brandmeldeanlage) and intruder alarm (Einbruchmeldeanlage) systems. The company also lists HolBit, a proprietary digital access control and monitoring solution, under its company information section, indicating an in-house product effort beyond pure installation services.

Rathmann's revenue mechanics are not disclosed; based on its single-site, regional field-service structure and breadth of service lines, the company appears to operate as a mid-sized regional Fachhandwerk (skilled trades) business with a mix of one-off project revenue (installations, E-Checks) and potentially recurring revenue from alarm monitoring and HolBit subscriptions. The company maintains an apprenticeship program ('Unsere Azubis') and a dedicated jobs page, indicating an internal vocational training pipeline. EU co-financing is acknowledged on the website, suggesting public-subsidy utilization for capex or training investments.
