When will I receive my first bill?
Once you have completed the online registration form and your request has been processed, the contract activation period will take approximately 3 weeks (if you are already with Endesa Energía this change will be much quicker).
Once the contract with Endesa has been activated, you will receive the last bill with your previous company (if you were already with Endesa it will be the last bill with your previous tariff). You will receive your first bill once the first billing period with Endesa has elapsed.
