Qué es bono social eléctrico: qué es y cómo comprobarlo (sin jerga)
The Bono Social is a discount mandated by the Spanish government to protect consumers with lower incomes or specific social situations.
La definición en una frase
It is a reduction of between 25% and 80% on the regulated electricity bill (PVPC) for those who meet specific income or family requirements.
Dónde aparece en la factura
It is always located in the 'Detalle de la Factura' (Bill Details) section, explicitly labeled as 'Descuento Bono Social'.
Por qué importa (dinero, decisiones y trampas típicas)
Choosing the wrong tariff can cost you hundreds of euros a year. The Bono Social isn't just a discount; it's a different way of being billed.
El error más común
Many users believe they have the Bono Social because they are with a large company like Iberdrola or Endesa, but they are actually in their 'Free Market' division where the discount cannot be applied.
La pista que casi nadie mira
Check the 'Social Power' limit. The discount only applies up to a certain kWh consumption limit; exceeding this means you pay the full PVPC price for the remainder.
Cómo comprobarlo en 60 segundos (checklist de auditor)
A forensic audit doesn't have to be long. Follow these steps to verify your status.
Qué buscar en el PDF
Look for the name of your provider. If it doesn't end in 'Comercializador de Referencia', you definitely do not have the Bono Social.
Qué anotar para comparar
Note your 'Potencia Contratada' and your 'Consumo Total'. These two numbers are the DNA of your energy costs.

The Landlord's Oversight: A Real-World Audit
A property owner in Madrid managing a rental apartment suspected the bills were too high despite the tenant being a student. Upon performing a forensic audit of the PDF, we found that while the tenant could have qualified for the Bono Social, the contract was still on a standard market rate. Even worse, the power was oversized.
Hallazgos
- ✓Contracted power was 4.6 kW, while real-time peaks never exceeded 2.8 kW.
- ✓A hidden 'extra service' fee of 6.99 €/month was being charged for maintenance.
- ✓The effective price was 0.23 €/kWh, nearly double what a Bono Social rate would offer.
