Installation services

Citizen-orientated

The AENOR SI Mark certifies the quality of the installation process in construction and/or its maintenance, focused on companies that carry out installation services in any construction sector and maintenance in services usually aimed at citizens.

It is one of AENOR's voluntary quality marks, which has great prestige and recognition at both national and international level. Companies that have completed the certification process to prove that they comply with the necessary requirements and have received the corresponding certificate from AENOR may use this mark, which symbolises the quality and safety of their products.

The aim of the mark is to ensure that the individuals who are responsible for installing systems in both new buildings and during renovation works have adequate training and continue to develop their skills on an ongoing basis. The mark is also proof that installation and maintenance companies have adopted best practices in the provision of maintenance services.

To do this, AENOR offers these companies a certification carried out by an entity independent of the interested parties, in accordance with their characteristics.


Once it passes the certification process, the organisation obtains:

  • AENOR certificate for the certified installation service
  • Licence to use the AENOR SI Mark
