Serium Instalaciones

What Serium Instalaciones does

Serium Instalaciones (legal name: Serium Instalaciones Eléctricas, SL) is a Madrid-based electrical installation services firm serving construction companies across Spain. Founded in 2005 and operating from a single headquarters in the Madrid district (c. Aguacate 41), the company employs approximately 11 people and functions as a Sociedad Limitada (SL), a privately-held Spanish limited liability structure with no external investors or parent entity disclosed.

The firm's core offering is an integrated, end-to-end electrical installation service covering design, execution, and official legalisation before regulatory bodies. Its service portfolio spans six lines: low and medium voltage electrical installations; fire protection systems (detection, alarms, extinction); forced air ventilation with CO detection for enclosed spaces such as underground parking; EV charging station installation; solar photovoltaic panel installation; and ancillary services including electrical networks, transformation centres, public lighting, and urbanization works. The value proposition is bundling these specialist trades under a single provider to simplify vendor management for construction-firm clients, with execution references across residential, commercial, industrial, educational, sports, and public infrastructure building types.

Commercially, Serium operates a direct B2B sales-led model. Customer acquisition is driven by the company website (serium.es), phone, and email outreach to construction company decision-makers. Pricing is project-by-project and not publicly disclosed; revenue is generated through one-time professional services fees rather than recurring contracts. The geographic footprint is domestic, concentrated in the Community of Madrid. No revenue figures, customer logos, awards, certifications, partnerships, or active social media presence are disclosed in the available sources, and the firm has no documented funding history, subsidiaries, or M&A activity.

Broad incumbents

• Elecnor: Elecnor is a major Spanish infrastructure, energy, and electrical installation company operating nationally with much larger scale. It is comparable to Serium as it executes low and medium voltage electrical installations, fire protection, and renewable energy projects across commercial, industrial, and public-sector buildings—Serium's core domain—though at vastly greater scale and geographic reach.
• SICE: SICE is a Spanish technology and electrical infrastructure integrator operating in urban services, transportation, and energy. It is comparable as it provides integrated electrical installation and system integration services for tunnels, public lighting, and buildings—directly overlapping Serium's transformation centers, public lighting, and urbanization offerings.
• Cobra Group (ACS): Cobra is a large Spanish industrial services and electrical installation firm owned by ACS Group, executing complex installations across energy, telecom, and building infrastructure. It is comparable as a broad incumbent offering overlapping electrical installation, fire systems, and energy services to construction and infrastructure clients across Spain and globally.
• Veolia España: Veolia España provides facility management, energy efficiency, and building technical services across Spain. It is comparable as a broader incumbent offering building engineering, electrical maintenance, and HVAC-related services that overlap with Serium's ventilation, electrical, and energy efficiency scope.

Regional players

• Cuerva Energía: Cuerva Energía is a Spanish electrical and energy services firm based in southern Spain. It is comparable as a regional player providing electrical infrastructure, renewable energy, and EV charging installation services to commercial and public-sector clients—overlapping with Serium's renewable and EV offering though in a different Spanish region.
• Ortiz Construcciones y Proyectos: Ortiz is a Spanish construction group with in-house electrical and MEP installation capabilities. It is comparable as it both constructs buildings and self-performs electrical installations for B2B construction clients in Spain, overlapping Serium's customer profile though from a general contractor perspective.

Emerging players

• Repsolar: Repsolar is a Spanish solar PV installation and engineering company. It is comparable as an emerging player focused specifically on the solar panel installation service that Serium also offers, competing for similar residential and commercial customers across Spain.
• API Movilidad (Cargacoches): API Movilidad is a Spanish EV charging infrastructure operator and installer. It is comparable as an emerging player in the same EV charging installation vertical Serium now serves, although it operates at a more specialized, scaled level targeting commercial and residential deployments across Spain.

Direct peers

• Eurocontrol (Spain): Eurocontrol is a Spanish industrial services firm providing inspection, testing, and technical services to industrial and energy clients. It is comparable as a direct peer offering specialized installation, commissioning, and regulatory compliance services for industrial clients—closely aligning with Serium's legalization and compliance work for construction clients.
• Instalaciones y Mantenimientos IMA: IMA is a Spanish electrical installation and maintenance contractor serving commercial and industrial clients.
