Grants and subsidies for renovating
There is public money for renovation — with strict rules. The most important one: it must almost always be requested BEFORE the works start.

Short answer
What grants exist right now?
Three blocks are open in Barcelona: European Next Generation funds for energy renovation, run in Catalonia through Generalitat calls; municipal grants from IMHAB, the city housing institute, covering common elements, accessibility, lifts and façades; and Spanish income-tax (IRPF) deductions where a certified energy improvement is proven. All of them share one rule that catches owners out — you apply BEFORE the works start, and an energy certificate taken before demolition is what fixes the baseline the saving is measured against. Purely cosmetic work scores nothing: a new kitchen or bathroom with no energy gain does not qualify. Non-residents should note the split — property-linked grants are generally open to you, but IRPF deductions only benefit people who pay Spanish income tax.
Three blocks: European Next Generation funds for energy-efficiency renovation (managed in Catalonia through Generalitat calls), Barcelona municipal grants (IMHAB — the city housing institute) for common elements and accessibility, and Spanish income-tax (IRPF) deductions for works with certified energy improvement.
The three blocks
- Next Generation: energy renovation of buildings and homes, with percentages growing with the energy saving achieved
- Municipal grants (IMHAB): common elements, accessibility, lifts, façades — by open calls
- IRPF deductions: a share of the works deductible if energy improvement is proven with before/after certificates
The golden rule
Apply BEFORE starting: most calls do not accept works already under way. And keep everything — prior energy certificates, invoices, the project. No paperwork, no grant. Non-resident owners should check their tax position: IRPF deductions apply to Spanish income-tax payers.
Eligibility
What must you comply with to collect?
Each line has its own conditions, but some constants repeat across all of them.
Usual requirements
- An energy certificate BEFORE the works: it sets the baseline for the saving
- A project or technical report justifying the improvement
- A registered company and proper invoices: payments by bank transfer, not cash
- An energy certificate AFTER, proving the saving achieved
- In buildings: a community resolution and often a minimum share of owners in agreement
What usually falls outside
Purely aesthetic renovation: a new kitchen or bathroom with no energy improvement does not score. What scores: insulation, windows, aerothermal heat pumps, solar panels, boiler replacement.
In practice
How do we build grants into the renovation?
A grant is not a separate errand — it shapes the project. If you want to qualify, the works are designed to score, and the calendar is planned around the call.
How we handle grants
- We identify the applicable line before the project is closed
- We commission the prior energy certificate as the first step
- We design the intervention to reach the call’s saving threshold
- We document the works with invoices and certificates fit for the claim
An honest warning
Calls open and close, and percentages change. We do not promise amounts: we verify what is open at the moment of the project and put it in writing.
Frequently asked
Common questions
Almost never: most calls require the application before works begin. That is why grants are checked BEFORE signing the quote, not after.
Façade or roof insulation, window replacement, aerothermal heat pumps, solar panels and boiler replacement. Purely aesthetic renovation does not score.
The proof of the saving: an official certificate before the works fixes the baseline, and one after proves the improvement. Without both, neither grant nor deduction can be justified.
No: a percentage of the eligible works, growing with the energy saving achieved. The rest of the renovation — finishes, kitchen, bathrooms — is at the owner’s cost.
For grants tied to the property, generally yes — through the community or as an owner. IRPF deductions, however, only benefit those who pay Spanish income tax. We flag which line applies to your case before the project is closed.
