Electricidad Llano was established in 1990 to attend to ever-increasing needs of electrical installations.
Technological development and the mobilisation of the market created a demand for more complete and diversified services, which, in turn, led LLANO to set up the air conditioning (Clima) and fire protection (PCI) divisions.

In a short period of time, LLANO became a leading company in Asturias and moved on to Spanish and international markets.

We now operate under the LLANO SERVICIOS E INSTALACIONES brand and can deal with comprehensive jobs, increasingly requested by our clients.

The principles of commitment, safety, quality and effectiveness are not just a declaration of intentions; they became real and came into effect when LLANO became the first company in Asturias to be certified under the UNE-EN ISO 9001, 14001, 18001 and 50001 standards for:

  • Designing high- and low-voltage electric installations and fire protection installations,
  • Installing, repairing and maintaining high- and low-voltage electric equipment and systems,
  • Installing, inspecting, maintaining, recharging, servicing and date-stamping fire extinguishers and fire protection systems,
  • Designing and implementing projects and installing and maintaining thermal cooling/heating installations.


Llano has become a leading company through its efforts to ensure continuous improvement and client satisfaction.

A commitment to continuous training, energy efficiency and technological innovation has meant Llano is prepared to deal with the new challenges of the future and can develop its business wherever it needs to.


are the four basic pillars on which our company service policy rests"
