Register of Accredited Companies - Construction

In Spanish, Registro de Empresas Accreditadas (REA).

The purpose of the Accredited Companies Registry (REA) is to certify that the companies that operate in the construction sector meet the capacity and quality requirements for occupational risk prevention. Any company that intends to be hired or subcontracted for work on a construction site, must be registered in the Registry of Accredited Companies dependent on the labor authority where the company’s registered office is located. As of August 26, 2008 companies that hire or subcontract the performance of any work on a work, must prove that their contractor companies or subcontractors are registered in the Registry, requesting for this a certificate of registration.

The REA has been designed and implemented in accordance with the provisions of Royal Decree 1109/2007, of August 24, which develops the law 32/2006, of October 18, regulating subcontracting in the Sector of the Construction.

Info from the Spanish Government with regards to the necessity for businesses established in other countries, who displace workers to Spain temporarily.

FAQS no. 2.9. The companies not established in Spain that move with their workers, do they have to register in the Register of Accredited Companies?

For companies that provide transnational services, a simplified registration procedure is envisaged, characterized by the following characteristics: Registration will not be necessary for trips of less than 8 days. The first communication of displacement required by article 5 of Law 45/1999, of November 29, will have the character of application for registration, to which must be attached the declaration on compliance with the requirement of solvency and business quality (model Annex IA Royal Decree 1109/2007). From the moment of the communication they will be considered provisionally registered, until the labor authority effectively registers or denies the inscription in its Registry. In the subsequent displacement communications, the registration number in the REA shall be stated.
