I currently have a contract with a Reference Reseller Company. Will I once again be billed monthly with estimated readings?
According to Royal Decree 1718/2012, December 28th, the change is mandatory. Furthermore, here at Endesa Energía, XXI, we believe this to be a positive change, since bills with estimated readings will no longer be issued.
From April 1, 2013 onwards you'll receive bills every two months, always using actual readings.
