Energy-upgrading a home —insulation, windows, aerothermal systems, photovoltaics— has two drivers: bill savings and the energy rehabilitation grants in the Valencian Community, which can cover a very significant part of the work. This is the map of what exists and how to apply without getting lost.
The three buckets of support
1. Direct subsidies for the work
The Generalitat, through its rehabilitation programmes (managed by the Housing Department and IVACE), announces grants for measures that reduce consumption: building envelope, joinery, efficient heating/cooling and renewables. Percentages increase the greater the achieved energy savings and for whole buildings versus individual dwellings. These calls have limited deadlines and funds: the key is to learn about them in time and submit the technical documentation correctly prepared.
2. IRPF tax deductions
Energy improvement works have benefited from national deductions of up to 20%, 40% or 60% depending on the accredited savings (reduction in demand, in non‑renewable primary energy consumption or building rehabilitation). The essential requirement: energy certificate before and after the work demonstrating the improvement. These deductions have been extended for specific tax years; check their validity for the year of your works before relying on them.
3. Municipal discounts
Many town councils grant reductions on the ICIO construction tax and on IBI for several years for installing photovoltaics or improving efficiency. It varies by municipality (Torrevieja, Orihuela, Guardamar have their own regulations): check before applying for the permit, because some discounts must be requested at that time.
The paperwork that decides whether you get paid
Virtually all supports revolve around the same documents: initial energy certificate, project or technical report, invoices in your name paid by traceable means (no cash) and final certificate proving the improvement. Those who put these papers in order receive payment; those who improvise them do not.
And if the plan is to sell?
Then the question changes: it’s not “what grants exist,” but “which improvement returns most in the sale price.” They don’t always coincide: sometimes a light refurbishment and selling is more profitable, leaving the major works to the buyer (the grants will apply to them too, and many foreign buyers value a project like that). That calculation —cost of the work vs the real value increase in your area— is what we do at Mayrasa with a free market appraisal, and from our real estate advisory we guide you with the appropriate technicians for the rest. Before spending on works, calculate what you recover.
