Energy grants in Spain
Up to 40 % of your window replacement, back in your pocket.
Changing old windows is one of the most effective energy improvements you can make to a home in Spain — and there is public money to encourage it. Most owners simply never claim it.
What is available
Two routes, and they can be combined.
The national income tax deduction gives private owners a percentage of the cost back through their Spanish tax return, rising with the energy improvement achieved. For a typical window replacement that is up to 40 %.
On top of that, every autonomous community runs its own grant programmes for energy renovation, Andalucía included. Where a whole building is upgraded and the savings are substantial, the combined support can go considerably higher.
Which one fits your project depends on the property, the scope of work and what is open at the time. We will tell you plainly which is worth pursuing — including when the honest answer is neither.
Get this part right
Three things decide whether you get the money.
Apply before the work starts
This is where most claims are lost. Begin the installation before the application is in and the grant is usually gone for good, with no way to correct it. Talk to us early.
Get the energy certificate done twice
A qualified technician certifies the property before the work and again afterwards, showing the improvement achieved. We can point you to people who do this.
Pay traceably
Bank transfer or card, to a registered company, with a proper invoice. Cash payments cannot be claimed.
Our part
We give your technician everything they need.
We are window makers, not tax advisers — but we know which documents an application asks for, and we prepare them without being chased.
Performance figures for the products you have chosen, declarations of performance, an invoice specified the way the authorities want to see it, and a clear before-and-after description of what was replaced. If you need a technician or a gestor, we will point you toward one we have worked with.
Grant levels, deadlines and conditions are set by the Spanish state and by each autonomous community, and they change from year to year. The figures on this page are indicative. We confirm what applies to your property, wherever it is, at the time we quote.
