You can switch as often as you like, as long as your energy contract allows it and you respect the usual 30-day notice period. However, we don’t recommend switching endlessly.
With a 1-year fixed contract, you can switch once a year at the end of the contract. With a 2-year contract, that’s once every two years. If you have a variable or dynamic contract, you’re free to switch at any time — just make sure to observe the notice period.
