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 types of companies a certification process performed by a body that is independent of the interested parties, in accordance with their characteristics. This enables them to comply with the requirements to obtain certification and helps customers and users better understand the quality of their installation and/or maintenance services.

As it is designed for installation companies, the emphasis is on professional qualifications. To obtain this certification, businesses that provide installation services within the construction sector must ensure that all their installation professionals pass a specific exam as part of the company's certification process.

AENOR has developed Specific Regulations for each product or system installed, which include all the steps performed during the certification process.
