Comprehensive advisory for Spain's construction sector

Spain’s construction sector is one of the pillars of the country’s productive economy. With more than 367,869 active companies and nearly 1,484,372 workers registered with Social Security, it accounts for 10.6% of the European Union’s construction market — a position that reflects both the scale of the Spanish market and its relevance within the European project of energy transition and renovation of the built environment. The sector is experiencing a period of intense activity driven by residential demand, building energy renovation programmes backed by NextGenerationEU funds, and the tendering of major public infrastructure projects.

The fragmentation of the business fabric — more than three in four companies are micro-enterprises or self-employed — makes the sector one of the most exposed to employment, tax and regulatory contingencies. Planning law is managed at regional and municipal level, the VAT regime contains sector-specific reverse charge rules that differ from other industries, the Subcontracting Act imposes strict limits and documentary obligations across the supply chain, and occupational health and safety requirements are particularly stringent on building sites. Managing these dimensions well is what separates a profitable project from one that accumulates contingent liabilities.

At BMC we advise property developers, civil engineering contractors, installation and maintenance companies, and specialist subcontractors on all tax, legal and employment aspects of their operations. Our services include structuring the development vehicle (purpose-specific company, joint venture, UTE), tax planning for the development project from land acquisition onwards, reviewing the VAT reverse charge impact throughout the payment chain, urban planning and land registry due diligence, and drafting construction contracts (turnkey, unit-rate, and public-private collaboration agreements). We also assist with public tender bids and with preparing contractual terms for engagement with subcontractors.

On the employment side, construction is one of the sectors with the greatest exposure to joint and several liability for subcontractor debts, penalties for non-compliance with the Subcontracting Register, and workplace accidents with criminal consequences. Our employment law team advises on health and safety plans, multi-employer coordination obligations, applicable sector collective agreements (Convenio General de la Construcción) and the seasonal temporary redundancy schemes (ERTEs) common in the industry. We also manage applications for grants and subsidies covering energy renovation works, digital construction technology adoption and vocational training programmes.

Key services for the construction sector

Tax planning in construction requires mastery of the VAT reverse-charge mechanism for construction services (article 84.One.2f of Spain’s VAT Law), which shifts the VAT liability to the business recipient. Correctly identifying each transaction as subject to reverse charge is critical to avoid penalties. For property developers, the full cycle of taxes on a development — VAT on land acquisition and construction, municipal capital gains tax (plusvalía), corporate tax on the developer’s margin — must be modelled from project inception.

Employment law in construction presents specific challenges: the General Construction Sector Collective Agreement (Convenio General del Sector de la Construcción) sets detailed rules on working hours, safety allowances, temporary posting supplements and the liability chain between principal contractors and subcontractors for social security obligations. Workplace safety compliance is an area of particularly intense enforcement, with significant criminal liability exposure for companies that fail to meet their obligations under the Subcontracting Law.

Due diligence in construction M&A must cover pending administrative and planning authorisations for projects in the pipeline, construction and subcontractor liability exposures, ongoing employment disputes, environmental liabilities from contaminated land, and contract-by-contract analysis of completion risk. BMC coordinates all workstreams to deliver integrated reports within transaction timelines.

Regulatory challenges for the construction sector

ESG reporting is becoming central to the construction sector. EU Taxonomy requirements classify construction activities as sustainable or not for green finance purposes; the Energy Performance of Buildings Directive drives mandatory renovation investment; and major developers face increasing pressure from institutional investors to adopt credible decarbonisation roadmaps. We advise construction firms on developing ESG strategies and structuring green bond or sustainability-linked credit facilities.

Criminal corporate liability is a particularly high risk in construction. Offences against workers’ rights (including workplace safety), planning law violations and corruption in public contracts can generate corporate criminal liability under article 31 bis of the Criminal Code. Implementing a construction-sector-specific criminal compliance programme — with a whistleblower channel, contracting policies and specific training — is the best defence against a potential judicial investigation.

KPIs for Spain’s construction sector 2025-2026

Spain’s construction sector counts more than 367,000 active companies and approximately 1.5 million workers, accounting for 10.6% of the EU construction market. Spain’s residential housing new-build volume reached 110,000 units in 2024, well below the estimated annual need of 200,000-250,000 units, supporting a structurally positive outlook. Public infrastructure investment from the National Infrastructure Plan and EU cohesion funds reached €22 billion in awarded contracts in 2024.
