🏠 Grants for a heat pump or insulation in Spain: where do I apply?

The short answer

Most countries support home renovation with grants, tax credits or cheap loans. The schemes change often, so always check the official portal before you order work.

📜 The rules in Spain

Grants for heat pumps and insulation

Housing energy-renovation grants from the Plan de Recuperación (Real Decreto 853/2021) and IDAE programmes such as PREE are run by the autonomous communities: you apply through your region's calls. Several national calls are already closed, so check your region first.

  • Income-tax (IRPF) deductions for home energy-efficiency works: 20% (less heating/cooling demand), 40% (less non-renewable primary energy) and 60% (building renovation). You need energy certificates from before and after the works. (sede.agenciatributaria.gob.es)
  • Real Decreto-ley 7/2026 extended the 20% and 40% deductions to 31 December 2026 and the deduction for works in mainly residential buildings to 31 December 2027. (sede.agenciatributaria.gob.es)
