Respuesta rápida
The Bono Social Eléctrico is Spain's regulated electricity discount (25–80%) for vulnerable consumers. It only applies on the PVPC regulated tariff through a Comercializadora de Referencia (reference supplier), has contracted-power limits, and must be renewed every two years. If you're on the free market, you can't receive it — switching to PVPC with a reference supplier is step one.

What is the Bono Social Electricity Discount (Without Jargon)
The Bono Social is a discount mandated by the Spanish government to protect consumers with lower incomes or specific social situations.
The Definition in One Sentence
It is a reduction of between 25% and 80% on the regulated electricity bill (PVPC) for those who meet specific income or family requirements.
Where It Appears on the Bill
It is always located in the 'Detalle de la Factura' (Bill Details) section, explicitly labeled as 'Descuento Bono Social'.
Why It Matters (Money, Decisions and Typical Traps)
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.
The Most Common Mistake
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.
The Clue Almost No One Checks
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.
How to Verify It in 60 Seconds (Auditor’s Checklist)
A forensic audit doesn't have to be long. Follow these steps to verify your status.
What to Search For in the 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.
What to Note Down for Comparison
Note your 'Potencia Contratada' and your 'Consumo Total'. These two numbers are the DNA of your energy costs.

The Romanian Cleaner in Zaragoza Missing Her Discount
A Romanian single mother in a 55 m² social housing flat in Zaragoza qualified for the Bono Social but didn’t know it — she was still on a branded free-market plan from a big utility. Our audit flagged it immediately. Once migrated to PVPC with a reference supplier and approved as 'vulnerable consumer', she cut €18/month off her bill.
Hallazgos
- ✓On free-market plan despite meeting Bono Social income thresholds.
- ✓Contracted power of 3.45 kW, within the 10 kW Bono Social cap.
- ✓Savings of €18/month (~€216/year) after migration and Bono Social approval.
