ServiceHaus

What ServiceHaus does

ServiceHaus GmbH is a Mannheim-based municipal digital services company and wholly-owned subsidiary of GBG-Unternehmensgruppe GmbH, the housing company of the city of Mannheim. Founded in 1998 as a joint venture between GBG and MVV Energie AG, it became fully owned by GBG in 2009 and now serves as the in-house digital infrastructure provider for GBG's residential housing portfolio of 20,000+ units, while also offering services to external property owners (Wohnungseigentümergemeinschaften) in the Mannheim region. The company is led by managing directors Robin Schwarz and Markus Abegg and reports a parent-staffed core team of 11–50 employees, with additional workforce at two non-profit subsidiaries: Chance Bürgerservice Mannheim gGmbH (86 employees, social services) and Markthaus Mannheim gGmbH (81 employees, secondhand retail and integration employment for people with disabilities).

ServiceHaus operates two principal service lines. Tenant services include TV-Kabelanschluss (cable TV from €18/month), fiber internet enablement through Telecom Solutions 61 GmbH, Mieterstrom/PV-Strom (rooftop photovoltaic electricity priced at minimum 10% below MVV Mannheim, with Wattline backup), intelligent parking using Free Flow license plate recognition (347 spaces at Quartiersparkhaus Spinelli, 110 at P2 Wasserwerkstraße Franklin), ServiceBox parcel lockers, and Campus-WLAN. Property owner services include transparent heating and water cost billing with EED-compliant smart metering gateways (Engelmann HCA E2, Sensostar, WaterStar devices) plus wireless smoke detector service with gateway-based continuous monitoring. The technical backbone is a Smart Metering Gateway platform that networks heat cost allocators, heat meters, water meters, and smoke detectors and transmits consolidated consumption data over the internet for billing and remote monitoring.

Revenue is generated primarily through recurring monthly subscriptions (TV cable, Mieterstrom, meter rentals), transaction-based fees (parking, Vodafone-enabled cable internet), and contract-based services to property owners. Distribution combines direct self-service via the service-haus.de website, a customer service hotline (0621 3096-8228), and dedicated sales for property owners, with channel partnerships including Vodafone (internet/telecom over cable), Telecom Solutions 61 GmbH (Glasfaser), Rehnig (cable network 24h hotline), Evopark (parking technology), and Engelmann, QUNDIS, Ei Electronics, and metr for smart building hardware and IoT. The company holds a berufundfamilie family-friendly employer certification (December 2023, group-level) and aligns website accessibility with WCAG 2.2 and EN 301 549.

Regional players

• Stadtwerke Heidelberg: Neighboring municipal utility in the Rhein-Neckar region. Comparable in serving municipal tenants with energy, telecommunications, and smart-city services, though operating in Heidelberg rather than Mannheim.
• MVV Energie AG: Mannheim-based municipal utility and former co-founder of ServiceHaus. Comparable in energy supply, Mieterstrom, and smart metering operations, but operates on a regional/national scale versus ServiceHaus's GBG-anchored model.

Emerging players

• METR Building Management Systems GmbH: Berlin-based technology partner providing digital building and metering IoT solutions to ServiceHaus. Comparable in smart-building IoT and metering technology, but positioned as a technology supplier rather than full-service operator.

Direct peers

• Techem GmbH: Major German provider of metering, submetering, and energy services for residential housing. Directly comparable to ServiceHaus's metering, heating-cost billing, and smoke detector service lines, serving the same Wohnungswirtschaft segment with EED-compliant offerings.

Broad incumbents
