Where do I complain about my energy company in Czechia?

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 Czechia

What to do first

Raise the problem with your supplier first and keep the correspondence. Then send ERÚ a written proposal (post, data box eeuaau7 or signed e-mail) with your contract, bills and communication. No fee; decision within 90 days (120 if complex) and binding.
