How to switch provider?
  1. Choose your new provider. They handle the cancellation of your current contract themselves — you don't need to do anything else.
  2. Prepare your info. Meter EAN code (on the bill, 18 digits), recent meter reading, bank IBAN.
  3. No fees, no interruption. The switch is free, takes 3 weeks on average, and electricity never stops.
  4. Check every year. Differences can reach €200-400 per year. Re-comparing every 12 months has become the norm.
