How do I switch electricity or gas supplier in Slovenia?

The short answer

Your supply does not stop when you switch: the cables, pipes and meter stay the same. Only the company that sends the bill changes.

📜 The rules in Slovenia

Switching supplier

Switching supplier is free and must be completed within 21 days of a complete request. You only contact the new supplier, which can handle everything. You get a final bill from the old supplier within 6 weeks. Leaving within the first year may cost what your contract says.

The market

The electricity market has been fully open since July 2007: every household can choose its supplier. Gas from the grid is also bought from a supplier of your choice. The network part of the bill stays the same whoever supplies you.

Cooling-off period

For contracts signed at the door, by phone or online you can withdraw within 14 days without giving a reason. For service contracts such as energy supply the period runs from the day the contract is signed.
