How to change an electricity seller

If you use an universal service, please keep in mind
  • Consumers of the universal service do not have a contract with an electricity seller,
  • If you wish to end the universal service and choose a specific electricity seller and package, you have to enter into a contract with an electricity seller at least 21 days before the start of the next month.

See the table for deadlines of entering into a contract if you wish to connect to an electricity seller from the first day of the following month.

If you are a customer of an electricity seller, please keep in mind
  • The electricity seller whose customer you wish to become may offer you the option of ending your contract with your current seller based on your authorisation (authorising will make the change easier for you),
  • If you do not have the option of authorising or do not wish to do so, you have to notify your current energy seller of ending the contract yourself at least 30 days in advance (the exact notification time is specified in your contract).

See the table for deadlines of notifying your current electricity seller of ending the contract if you wish to start using the services of a new electricity seller from the first day of the following month.

If you entered into a contract with an electricity seller though doorstep selling or via telecommunications and have also authorised the new seller to end your contract to your current seller and then use the 14-day right of withdrawal, you have to take into consideration that the new electricity seller might have already notified your current seller of ending the contract. In this case you may end up using the universal service for at least a month if, due to the limitations on deadlines, you are unable to enter into a contract taking effect from the following month.
