Get your account details together
Check the name and email on the account and, if you have one, an account or customer number before anything else. A request that does not match the account on file at Nexus Energia is the easiest one to set aside.

Post it with proof of delivery
Post it by certified mail to Nexus Energia in Madrid, Spain, using the exact address below, and note the tracking number.

How cancelling by mail works
A subscription ends when the company records your request, not when you stop using it, and a letter is the record you can show later.
A mailed letter is slower than a phone call but it is the version that proves what you asked for and when.
