What BRUNATA-METRONA does

BRUNATA-METRONA is a German private group of metering and energy service companies, organized around three independent parent entities headquartered in Hamburg, Cologne/Hürth, and Munich (founded 1954, 1953, and 1949 respectively). The group provides consumption-based measurement, analysis, and billing of heating, water, and ancillary operating costs for residential and commercial real estate, supported by proprietary metering devices (heat cost allocators, heat meters, water meters, wireless Funksysteme) manufactured in-house by subsidiary METRONA Union. Its technology stack centers on remote-readable metering hardware, ARGE Heiwako-standard data exchange (INTAS) for property-management ERP integration, the BRUdirekt tenant app, and a web-based customer portal infrastructure, with a test-version FAQ chatbot for customer self-service.

The company serves German property management companies, housing associations, homeowner associations, private landlords, and commercial real estate operators, managing approximately 25 million metering devices across roughly 3 million residential and commercial units. Revenue is generated primarily through subscription/recurring contracts: annual heating cost and ancillary cost billing per unit, recurring smoke alarm installation and inspection (Rauchmelderservice, including DIN-14676-compliant remote inspection), smart metering subscriptions, submetering for energy utilities, and electronic invoicing. Complementary revenue streams include hardware sale/rental of Erfassungsgeräte, professional services for energy certificates (Energieausweis/GEG), drinking water analysis (Trinkwasseranalyse/Legionella), CO2 cost allocation (CO2KostAufG), and energy management consulting, augmented by subsidiaries myWarm (hydraulic balancing), cowelio (energy consulting), BlueMetering (Messstellenbetreiber), and field-service units BRU-MET and MoinTec. Distribution is hybrid: postal-code-based online quote requests, phone-based inside sales, and a nationwide physical network of more than 40 branches and 60+ service centers, with dedicated account managers serving large housing-industry clients. Pricing is not publicly disclosed; quotes are obtained by request.
