1. Are there subsidies for energy efficiency actions?
Yes. European decarbonization policies are backed by strong regulations and supported by the Next Generation EU funds, which in Spain are managed through the IDAE and distributed by the autonomous communities. Regional calls for different actions are published periodically.
It’s important to act based on your investment strategy, not just wait for subsidies, because aid programs are competitive and can change in conditions, amounts, and frequency. Funds may run out or have strict deadlines, and you risk missing opportunities or losing savings while waiting for aid.
With aid, the return on investment improves — but remember, approval and especially disbursement are not immediate.
There are permanent programs such as CAEs (Energy Saving Certificates), which offer financial compensation. Other forms include tax deductions (IS, IRPF, IBI) and ICIO tax rebates. Aid varies by region, city, and type of project. Tell us your location and we’ll study your options.

2. Is the application process difficult?
It’s more tedious than difficult. It involves a lot of paperwork, often in different formats and platforms. Be patient, read instructions (if available), and prepare all required documents in advance. Online forms can expire if not completed quickly.
Always list attached documents and save submission receipts. Rejections are common, often due to supposed missing documents, even when proof of submission exists. This is a way to restart their deadline.
Once approved, you’ll be asked for documentation throughout the project to prove the investment. If you prefer, you can authorize us and we’ll handle everything.

3. How should I justify the actions to secure the subsidy?
If you’ve already received confirmation of eligibility and provide complete documentation, the aid is guaranteed. Justification usually includes that eligibility approval, invoices, proof of payment, declarations, legal system certification (CIE), and geotagged photos.

4. How long does it take to get approved and receive the funds?
For Next Generation EU aid, approval can take 3 to 6 months, depending on the call and completeness of your application. Disbursement takes longer and depends on the regional government’s capacity. Some clients have waited up to 3.5 years, with an average around 2 years.
You should plan to fund the investment yourself initially. There are also CAEs and tax benefits (IS, IRPF, IBI, ICIO), depending on your location and the type of action.

5. Do I need a building permit?
Yes, but we can prepare all the documentation for you.

6. Is it a good idea to get an energy rating for the building before and after the project?
In 2023–2024, tax deductions were available for achieving an A or B rating, or a 30% reduction in non-renewable energy use. Although that incentive is no longer active, it may return. Improving your energy rating also boosts your property’s market value. So yes, it’s often worth it.
