Deduction for energy rehabilitation works
In which homes should you carry out the work, what are the deadlines, what works give you the right to the deduction, how do you prove the improvement, when and on what amount do you apply the deduction?
What is considered energy rehabilitation work for a building?
Those that allow a reduction in non-renewable primary energy consumption by at least 30 percent, or the improvement of the building's energy rating to obtain an "A" or "B" energy class on the same rating scale.
To prove this, you must have an energy efficiency certificate for the building in which the home is located, issued by the competent technician before the start of the works (for these purposes, the one issued at most two years prior to the start of the works will be valid) and at the end of the works.
