📶 How do I leave my phone or internet contract in Czechia?

Short answer

A first contract term is at most 24 months. Once it is over and the contract runs on, you can leave with short notice. If the provider changes the price or terms, you can usually leave without a fee.

⏱ DeadlineAfter the first term: the short notice period in the rules below. After a change of terms: act within the period in the provider’s message.

📜 Your rights

EUThe EU rule

EU consumer law applies in every EU country. Your country writes it into its own law — the national rule is below.

  • The first commitment period of a consumer contract is at most 24 months; countries may set a shorter maximum (Art. 105(1) Directive (EU) 2018/1972).
  • If the contract is automatically extended after that period, you may end it at any time with at most one month’s notice, paying only for the service during the notice period (Art. 105(3)).
  • Before an automatic extension the provider must tell you, on a durable medium, that the commitment ends, how to end the contract and its best tariffs (Art. 105(3)).
  • If the provider changes the contract terms, you may end the contract without further costs, unless the change is only to your benefit, purely administrative with no negative effect, or required by law (Art. 105(4)).
  • The provider must tell you about such a change at least one month in advance; you can end the contract within one month of that notice (countries may extend this to three months) (Art. 105(4)).

The rules in Czechia

A fixed-term consumer contract for phone or internet may last at most 24 months; a longer one counts as indefinite. After an automatic extension, you can terminate at any time free of charge with at most one month's notice.

  • The provider must inform you in text form at least one month before an automatic extension about the contract end and how to terminate it, and about its best prices. (e-sbirka.gov.cz)
  • Contract changes must be announced at least one month ahead. You can then terminate free of charge within one month of the notice, unless the change is purely beneficial, purely administrative or required by a change in the law. (e-sbirka.gov.cz)
  • Early termination of a fixed-term contract: a fee may be charged only if the contract ends within 3 months of signing, and at most one twentieth of the remaining monthly payments. (e-sbirka.gov.cz)
  • Billing or service complaints must be made within 2 months; the provider must settle them within 1 month. If you disagree, you can file an objection with ČTÚ within 1 month. (e-sbirka.gov.cz)

❓ Frequently asked questions

Can the provider charge the rest of the term when I leave after a price rise?

Not when the law gives you the right to leave without further costs because of a change of terms (see the rules below). A discounted phone you are still paying off may have to be paid.

What counts as a change of terms?

A price rise, fewer services or a slower speed are changes. A change that is only to your benefit or required by law is not.

Can I cancel a new contract taken online?

Yes, within 14 days of the contract, without a reason.
