"Next Generation EU renovation grants are the most significant financing opportunity for building owners in Catalonia in recent decades."
Building renovation in Barcelona is now one of the city's fastest-growing construction activities. The combination of an ageing building stock, growing mandatory ITE inspection requirements and the availability of European Next Generation funds has created an unprecedented opportunity for building owners who want to improve their communities.
1. The ITE inspection: when it is mandatory and how it works
The ITE (Technical Building Inspection) is mandatory in Barcelona for all buildings that have reached 45 years of age. A qualified professional (architect or architectural technician) inspects the condition of the facade, roof, communal services and structural elements, and issues a report classifying deficiencies as minor, significant or serious. Serious deficiencies require remediation works within a maximum of 6 months.
2. Renovation costs in Barcelona 2026
The costs of the most common renovation works in Barcelona are: main facade (waterproofing + ETICS): €180–€350/sqm of facade; flat roof (waterproofing + insulation): €90–€200/sqm; pitched roof retiling: €150–€280/sqm; lift installation in a 5-storey building without a lift: €40,000–€80,000; communal electrical network renewal: €8,000–€25,000 for a 10-unit building.
3. Next Generation EU grants: up to 80%
The Next Generation EU renovation grant programme finances between 40% and 80% of the works cost, depending on the reduction in non-renewable primary energy consumption achieved. To access the maximum 80%, the works must reduce non-renewable primary energy consumption by at least 60%. Eligible works include: thermal envelope improvements (facade, roof, windows), renewable energy installation (photovoltaic, heat pump) and communal heating and cooling system upgrades.
4. Managing the application process
The grant application process requires: a preliminary energy performance certificate, a technical project for the proposed works, a detailed quote from the executing company and an application through Catalonia's government grant manager (habitatge.gencat.cat). At Nosolo Design we manage the entire process from the initial energy diagnosis through to post-completion grant justification.
Conclusion
2026 is the year to act. Next Generation EU funds are available and deadlines are approaching. Energy-efficient building renovation in Barcelona is not only a comfort improvement: it is an investment that adds value to the property and reduces residents' energy bills.
