Aid to renovate homes is once again among the most consulted in 2026. The Government of Spain , together with the European funds NextGenerationEU, maintains open grants that can reach 21,400 euros for those who carry out certain actions in their habitual residence. All official information can be consulted through the platform of the Generalitat Valenciana on European funds and energy rehabilitation. However, accessing these amounts doesn't just depend on changing the kitchen or refurbishing the bathroom. The key to this aid is in a technical condition that many owners discover too late and that completely conditions the type of work that must be executed to receive the grant.
