REA Aragón 2026 Extension: What Construction Companies and Subcontractors Must Know

Key data

Construction companies and subcontractors operating in Aragón can continue managing their registration in the Accredited Companies Register (REA) exactly as they have until now. The addendum signed on 28 September 2026 between the Ministry of Labour and Social Economy and the Autonomous Community of Aragón extends the original 2022 agreement by four additional years, without modifying any of its clauses or commitments.

The regulatory reference is the Resolution of 29 September 2026 from the General Technical Secretariat, published in the BOE on 10 October 2026 with identifier BOE-A-2026-21148. The effectiveness of the addendum was conditional on its registration in the State Register of Cooperation Bodies and Institutions (REOICO) within a maximum period of 5 business days from its signing.

What does this regulation establish?

The Accredited Companies Register (REA) is a mandatory register regulated by Law 32/2006, of 18 October, regulating subcontracting in the construction sector. Any company wishing to act as a contractor or subcontractor in construction works must be registered in it, accrediting that it meets the requirements for solvency, training in risk prevention and productive organization.

Since 2022, the Ministry of Labour and Social Economy and the Autonomous Community of Aragón have collaborated through an agreement so that the management of this register is carried out entirely by electronic means. The addendum published now does not introduce substantive changes: its sole purpose is to extend the validity of that agreement for four more years.

Economic and operational impact

The direct impact of this extension on companies is null in terms of costs or additional burdens. There are no new fees, no new registration requirements and no adaptation deadlines to meet.

The real impact is positive: the continuity of the agreement ensures that construction companies in Aragón continue to have an agile electronic channel to manage their accreditation in the REA. Without this agreement, management could be interrupted or transferred to slower procedures, with the consequent risk of delays in accreditation that could prevent participation in tenders or signing subcontracting contracts.

What companies must keep in mind is that the obligation to register in the REA remains in force in accordance with Law 32/2006. The extension of the agreement does not exempt from this duty; it simply ensures that the electronic channel to comply with it in Aragón continues to be available.

Who does it affect?

• Construction companies with activity in Aragón that act as main contractors in construction works.
• Subcontracting companies that participate in subcontracting chains in works located in Aragón.
• New companies in the sector that want to register in the REA in Aragón: they will continue to do so electronically without interruptions.
• Compliance and HR departments of medium and large construction companies that manage the accreditation of their subcontractors.
• Legal advisors and management firms that process REA registrations on behalf of Aragonese companies.

It does not affect construction companies that operate exclusively outside Aragón, nor sectors other than construction.

Practical example

An electrical installation company based in Zaragoza regularly acts as a subcontractor in residential building works. To be hired by the main contractor, it needs to be registered in the REA in accordance with Law 32/2006.

Thanks to the extension of the agreement, this company can continue processing its renewal or updating of data in the REA through the electronic system enabled by the Autonomous Community of Aragón, without travel or physical paperwork, exactly as it has been doing since 2022. It does not need to do anything different from what it was already doing: the system does not change, the deadlines do not change and the requirements do not change.

If the agreement had not been extended and had expired, this company could have faced difficulties in managing its accreditation electronically in Aragón, with the risk of being temporarily removed from active registers and unable to participate in new works.

What should companies do now?

1. Verify that your company is registered in the REA if you operate as a contractor or subcontractor in Aragón. The registration obligation remains in force in accordance with Law 32/2006 and is not altered by this extension.
2. Check that REA data is up to date: company name, legal representatives, occupational risk prevention data. An outdated registration can cause problems in audits or tenders.
3. Do not complete any additional procedures specifically derived from this addendum: the electronic system continues operating normally and does not require any action from companies.
4. Inform your subcontractors that the REA system in Aragón remains active and that they must keep their own registration up to date to be able to work on your projects.
5. Keep registration documentation in the REA as part of the regulatory compliance file, especially if you participate in public tenders where it may be required.
