🚪 I signed an energy contract at the door or by phone in Czechia. Can I cancel?

The short answer

Contracts made at the door, by phone or online usually come with a cooling-off period in which you can cancel without giving a reason.

📜 The rules in Czechia

Cooling-off period

You can withdraw from a contract signed off-premises or at a distance within 14 days (30 days after an unsolicited home visit or sales event). When switching this way you can also terminate until the 15th day after supply starts (15-day notice).

❓ Questions

Do I need a reason?

No. During the cooling-off period you can cancel without a reason.

What if I already used energy?

You may have to pay for energy delivered at your request during the period, but not a penalty.

They said they were from my current supplier. Is that allowed?

No. Pretending to be your supplier is misleading. Report it.
