🧾 My energy bill is wrong or far too high in Czechia. What now?

The short answer

Most bill problems come from estimated meter readings, a wrong meter number or a changed advance payment. You have the right to a correct bill based on your real use.

📜 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.

Protection against cut-off

According to ERÚ, you can only be disconnected for non-payment after repeated failures: at least two different unpaid payments (e.g. two advances), each preceded by a reminder with a reasonable deadline. Threatening a cut-off after one missed advance may be illegal; contact ERÚ.

❓ Questions

Should I pay a bill I dispute?

If you can, pay the part you agree with and dispute the rest in writing. That protects you best.

Can the supplier estimate my use?

Yes, if no reading was available. You can always send a real reading and ask for a correction.

How far back can they bill me?

The limits differ per country. Ask the energy regulator if you get a large back-bill.
