The taxpayer asks whether the improvement in the energy efficiency of her dwelling can be proven through means other than an energy certificate, as one was not issued before the works began. The DGT responds that such a certificate is necessary to satisfy the requirements for the deduction.
Question posed For the purposes of applying the deduction provided for in the 50th additional provision of the LIRPF, the possibility of proving the energy efficiency of the dwelling prior to the execution of the works through means other than the energy certificate.
To prove compliance with the requirements for the deductions set forth in the 50th additional provision of the LIRPF, only energy efficiency certificates issued before the commencement of works are valid, provided that no more than two years have elapsed since their issuance. If a certificate issued prior to the commencement of works that complies with this period is not available, the deduction cannot be applied.
