LLANO

What LLANO does

LLANO (legal entity: ELECTRICIDAD LLANO, S.L.) is a privately held Spanish multi-division technical installation and maintenance services company headquartered in Siero, Asturias, with operations spanning national Spain and select international markets. Founded in 1990 by Andrés Llano Díaz and Ceferino Díaz Ron to fill a gap in the electrical-installation market in Asturias, the company has progressively diversified over three decades into five specialized divisions: Electricity (industrial electrical systems, high/low voltage, public lighting, EV charging), Climatization (HVAC, aerothermia, ventilation, thermal installations), Fire Protection (detection, suppression, sprinklers, fire-resistant canalizations), Telecommunications and Security (structured cabling, CCTV, access control, fiber optics), and Renewable Energy (photovoltaic, solar thermal, biomass, wind for industrial self-consumption).

The firm operates on a turnkey project delivery model — design and engineering, installation and commissioning, plus preventive and corrective maintenance — delivered through direct enterprise field sales to industrial, commercial/tertiary, agri-food/logistics, and public/institutional clients. Revenue is generated primarily through custom-priced professional-services engagements (project-based, multi-year contracts) and ongoing maintenance subscriptions, with hardware sales tied to renewable-energy deployments. The company holds ISO 9001, 14001, 45001, and 50001 certifications, operates a separate affiliated entity (LLANO SEGURIDAD, S.L.) for security services, and currently employs approximately 46 people.
