The building rehabilitation grants 2026 are at a peak moment: several lines of European aid are coming to an end, while the State extends tax incentives and the autonomous communities —Catalonia in particular— keep their own calls open. For property managers and community presidents, understanding what is current, what deadlines exist, and how it combines with the IRPF deduction or IBI bonus is key to not leaving public money on the table or taking unnecessary risks.
Next Generation Funds: the countdown has begun
The most important feature of 2026 is that Next Generation community aids are no longer an indefinitely open line. The Recovery Plan (Next Generation Funds) has a fixed expiration date, which forces communities to accelerate decisions if they have not yet started the process. In Catalonia, the Agència de l'Habitatge de Catalunya has established that rehabilitation offices are funded under this program until June 30, 2026, and actions must be completed before that same date. In Barcelona city, the housing consortium itself reminds that works must be completed before June 30, 2026, the deadline for applications, and their duration cannot exceed 12 months from the grant of aid. In practice, this means that any community wishing to apply for these funds should already have the project drafted and the board agreement approved.
Catalonia Rehabilitation Aids: who manages what
The Catalan map of Catalonia rehabilitation aids combines several bodies that are worth distinguishing. The Consorci de l'Habitatge de Barcelona, the Consorci Metropolità de l'Habitatge, the Agència de l'Habitatge de Catalunya, and the Institut Català d'Energia (ICAEN) are the main bodies offering aids and grants for rehabilitation. In general terms, the Generalitat manages programs for improving energy efficiency, grants for elevator installation and accessibility, comprehensive building rehabilitation, and improvement of habitability conditions. A relevant technical nuance: since 2025, these calls have excluded certain technologies, as grants for fossil fuel boilers have been discarded, in line with the European ErP directive that excludes gas, oil, and coal boilers. Many Catalan municipalities add their own incentives: some councils have their own rehabilitation programs and, in addition to grants, foresee ICIO exemptions or IBI bonuses, so it is advisable to consult directly with each town hall.
IRPF Deduction for Energy Efficiency Works: Extension Confirmed
One of the most relevant changes of the last year is the extension of deadlines for the IRPF deduction for energy efficiency works. According to the latest regulatory update, deductions for works to reduce heating and cooling demand and to improve non-renewable primary energy consumption in homes are extended until December 31, 2026, and until December 31, 2027, in the case of predominantly residential buildings. The amounts remain staggered: the 20% deduction applies to works that reduce heating and cooling demand by at least 7%, with a maximum annual base of 5,000 euros, while the 40% is aimed at actions that reduce non-renewable primary energy consumption by 30% or improve the energy rating to A or B, with a maximum annual base of 7,500 euros. For entire buildings, the 60% deduction for residential building energy rehabilitation is extended until December 31, 2027. It is important to remember that this deduction is individual: each owner applies it in their own declaration, and it is usually compatible with the direct grant received by the community, applied to the part of the investment not covered by that aid.
IBI and Other Municipal Incentives
In addition to state and regional aids, many councils offer complementary tax bonuses. In numerous municipalities, there is a 50% IBI bonus for three years for buildings that demonstrate energy improvements, while other Catalan municipalities, such as those of Barcelona, Girona, Tarragona, or Lleida, manage their own rehabilitation programs and contemplate ICIO exemptions or IBI reductions. These bonuses are not automatic: each community must expressly request them from their town hall, providing the technical documentation that proves the energy improvement achieved after the work.
How to Act from the Community Without Losing the Opportunity Window
Combining grant, tax deduction, and IBI bonus requires orderly management, with deadlines that cannot be improvised. Some practical steps for administrators and community presidents:
- Request the prior energy efficiency certificate as soon as possible, an essential requirement to prove the improvement to the Treasury and the body granting the grant.
- Check on the website of the Agència de l'Habitatge de Catalunya or the corresponding municipal consortium the status of the call and its justification deadline.
- Have technicians and companies with real experience in processing aids: a poorly dimensioned project can lead to the total or partial return of the grant.
- Inform the board of owners that the IRPF deduction is individual and compatible with the collective grant, so that each neighbor plans their declaration.
- Consult with the town hall if there are additional IBI bonuses or ICIO exemptions once the work is completed.
Managing in parallel a Next Generation grant, a regional call, and the tax procedures of each owner is, in many cases, the most complex part of the process. Therefore, more and more communities are turning to professionals specialized in energy rehabilitation and aid processing to avoid missing deadlines or documentation. In the ForConnect professional directory, you can find trusted technicians and companies for energy audits, projects, and work execution. And if your community already knows what action it needs, you can request a quote without obligation and compare options before the deadlines for these aids run out.
