Spain has officially extended the Next Generation EU tax deductions and subsidies for home energy efficiency upgrades until 2026. Specifically, homeowners in Valencia can claim a deduction of up to 40% (€3.000) by reducing their heating and cooling demand by at least 7%. To qualify, an Energy Performance Certificate (EPC) must be obtained before and after the works are carried out. This ultimately makes 2026 the best year to modernise your Valencian home while significantly reducing your tax bill.
1. The 2026 extension: Why the government is paying you
Backed by European recovery funds, the Spanish government is committed to decarbonising the housing stock. Many older buildings in Valencia’s city centre, such as those in Ruzafa and Extramurs, are energy-efficient ‘dinosaurs’.
Consequently, the authorities have extended the deadline for these tax breaks to 31 December 2026. This is not just a direct grant, but a substantial tax deduction on your IRPF (income tax), meaning the government effectively offsets a large proportion of your renovation costs.
2. Which renovations qualify for the €3.000 deduction?
Not all “fixer-upper” projects qualify. Specifically, the work must demonstrably improve the building’s thermal performance.
Eligible projects include:
- Window replacement: Replace old single-pane frames with PVC or aluminium frames featuring a thermal break.
- Insulation: High-quality insulation is added to external walls or ceilings.
- Aerothermy & solar: We install high-efficiency climate systems that reduce the use of non-renewable energy.
The magic numbers: To qualify for the 40% deduction (up to a limit of €3,000), you must demonstrate a reduction in heating and cooling demand of at least 7%. Alternatively, you can unlock higher tiers of the subsidy by achieving a 30% reduction in non-renewable primary energy.
3. The secret weapon: the Energy Performance Certificate (EPC)
You cannot claim this subsidy without the correct paperwork. Therefore, the Energy Certificate is the most important document.
- Step 1: Before you start the works, hire a technician to issue an EPC.
- Step 2: Complete the renovations, including the windows and insulation.
- Step 3: Ask the technician to issue a new EPC once the work is finished.
- Step 4: Submit these to the Generalitat Valenciana, and remember to include the figures in your next tax return.
Crucially, the post-renovation certificate must demonstrate a 7% improvement. Therefore, it is vital to work with an experienced architect or contractor who understands these metrics.
4. Maximising your ROI in 2026
Combining this subsidy with Valencia’s climate is a financially sensible decision. For example, installing high-quality windows not only gets you a tax break, but also:
- Lower utility bills: Save up to 30% on air conditioning costs in July and August!
- Increase resale value: As mentioned in our ‘Green Premium‘ guide, homes with a B rating sell faster.
- Improve comfort: Dramatically reduce the noise of Valencia’s busy streets.

- Trusted partners: We connect you with English-speaking architects who specialise in energy certificates.
- Tax coordination: We work with your Gestor to ensure that the deduction is applied correctly to your Spanish tax filings.
❓ Frequently Asked Questions (FAQ)
The subsidy is available to homeowners, usufructuaries and tenants carrying out energy-saving renovations to their main residence. The property must be located in the Valencian Community.
In order to qualify, the renovation must meet one of the following criteria:
– Energy demand reduction: A reduction in heating and cooling demand of at least 7%.
– Consumption reduction: A reduction in non-renewable primary energy consumption of at least 30%.
– Structural improvements: Modifications to the ‘thermal envelope’ (i.e. the façade), such as replacing old windows with high-efficiency double or triple glazing.
The subsidy covers 40% of the project’s total cost, up to a maximum of €3.000 per home. To qualify for the grant, the minimum investment required for the renovation is €1.000.
Under the current extension, applications must generally be submitted by early 2026. Deadlines may vary slightly depending on the specific call, but February 2026 is a key registration deadline. Importantly, all subsidised work must be completed and justified by 30 June 2026.
Yes, you must provide two Energy Efficiency Certificates (CEEs): one before the work begins and one after it is completed. These certificates will prove to the relevant authorities that the required energy savings have been achieved.
No. To prevent fraud and meet audit requirements, all payments to contractors or suppliers must be made by bank transfer, credit or debit card, or via a made-out-to-order cheque. Cash payments are strictly prohibited and will result in your claim being rejected.
Yes, in many cases you can combine direct subsidies with IRPF deductions. For instance, if you reduce your energy consumption by 30%, you could receive a 40% tax deduction (up to a limit of €3.000) on your next tax return, provided that you subtract the amount of the direct grant from the total deductible amount.
The application process is handled electronically through the official portal of the Generalitat Valenciana. As the process requires technical documentation and digital signatures, many homeowners opt to work with an ‘Energy Rehabilitation Agent’ or certified technician to handle the submission.
The direct €3.000 subsidy is intended for primary residences only. However, landlords may still be eligible to apply if the property is the permanent residence of their tenant (as proven by their empadronamiento).
– You will need your DNI/NIE and proof of property ownership, such as an Escritura or a Nota Simple.
– You will also need a Certificate of Empadronamiento to prove that this is your primary residence.
– An initial energy efficiency certificate (CEE).
– You will also need detailed quotes/proformas from your contractors.
– You will also need detailed invoices and proof of bank payments once works begin.
