Installation and maintenance services

Citizen-orientated

The AENOR Mark certifies the quality of installation processes in construction and/or maintenance, and is aimed at companies that carry out installation services in any construction sector and maintenance in services usually intended for citizens.

It is one of AENOR's voluntary quality marks, which is highly regarded both in Spain and abroad. 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 services.

The objective is to enhance the professionalization and continuous improvement of the staff of companies that carry out installation works in new buildings and in rehabilitation works, and in the installation and maintenance of spaces, as well as to accredit the adoption of best practices in the rendering of maintenance services by installation and maintenance companies.


Once it passes the certification process, the organisation obtains:

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