📣 Where do I complain about my energy company in Spain?

The short answer

Start with the company itself, in writing. If that does not solve it, an independent body settles disputes with energy companies.

📜 The rules in Spain

What to do first

First complain to your supplier or distributor; they must answer within 15 working days. If not satisfied, go to consumer arbitration (Juntas Arbitrales de Consumo), the ADR body your company belongs to, or your region's consumer office.
