L’Ajuntament de Barcelona has launched a new call for grants to improve the energy efficiency of homes with up to 6,000 euros in subsidies.
This 2025 has doubled the amount of aid, which was previously 3,000, and administrative procedures have been reduced to facilitate access to funds with fewer forms to fill out.
What are the grants for energy efficiency in Barcelona?
This aid program, promoted by the Barcelona Housing Consortium, has an investment of 10 million euros, financed in equal parts by the European Union’s Next Generation funds and the municipal budget.
The works subsidized by the program range from the replacement of windows, the improvement of the insulation of facades or roofs from the inside and the installation of air conditioning systems based on renewable energies.
The subsidies are aimed at owners, usufructuaries and tenants whose dwelling is their habitual and permanent residence.
The amount granted may not exceed the total cost of the investment, and the works must be completed before June 30, 2026.
To qualify for the grant, the minimum cost of the actions must be 1,000 euros. The funds may cover additional expenses such as professional fees, project drafting, technical certificates and other administrative costs, provided they are duly justified.
Requirements for these grants
Among the requirements, it is important to verify whether the building in question already has an open rehabilitation file, since in that case the corresponding call for applications must be consulted.
In addition, the subsidies are intended for single-family dwellings or within multi-family buildings, the eligible actions must have started after February 1, 2020 and investments in thermal generators using fossil fuels will not be financed.
The subsidies under this call are not compatible with other municipal rehabilitation programs, such as those aimed at specific neighborhoods (Besòs and Maresme, el Congrés and els Indians, la Pau, Trinitat Vella and Canyelles) or those focused on buildings for residential use in the ERRP area of the Pla de Barris.
However, if after applying for this aid the community of owners accesses a rehabilitation program at the building level, the incompatibility will not apply.
To learn about the requirements and the steps to follow to apply for the aid, information drop-downs have been made available on the Habitatge Barcelona website.
