10.11.17. For energy efficiency improvement works in residential buildings or single-family housing

Taxpayers will be able to deduct in the year in which the work to improve the energy efficiency of properties for residential use housing is completed: (not applicable to properties used for professional offices or for the exercise of economic activities)

  • 15% of the total amounts invested.

    The deduction base will be limited to €9,000 per taxpayer. If there were two taxpayers who generated the right to the deduction, the deduction base for each of them could not exceed 9,000 euros. The base may not exceed the result of applying the percentage of ownership in the property to the total amount invested.

    The base will be made up of the amounts actually paid for energy efficiency improvement works in residential buildings or single-family homes, by credit or debit card, bank transfer, personal check or deposit into accounts in credit institutions.

    In no case will amounts paid through legal tender money give the right to make this deduction.

  • The cost of the fees for obtaining the certificate justifying the letter change in the energy rating of the property, as well as the fees related to its registration in the Registry of Energy Efficiency Certificates of Buildings of the Autonomous Community of Galicia, with a single limit per certificate and registration of €150. Both this limit and the amount of the fees must be prorated based on the percentage of ownership in the property.

    • That they have the corresponding permits, authorizations or enabling titles.

    • That they improve the energy performance of buildings by reducing energy demand, improving the performance of thermal installations and/or incorporating equipment that uses renewable energy sources and whose main objective is to raise a letter on the energy rating scale for CO2 emissions and on the scale for non-renewable primary energy consumption.
