E.ON Hungária Zrt founded E.ON Energiaszolgáltató Kft on May 14, 2007 in order to perform public utility service for the power and gas companies that belong to the E.ON Group.
On December 31, 2013, E.ON Energiaszolgáltató Kft was split into two independent private limited companies. E.ON Energiakereskedelmi Kft, which was established through the split-off, took over the competitive market power and gas activities across the E.ON Group.
As a result of the split-off, E.ON Energiaszolgáltató Kft was responsible for supplying customers under universal service in the E.ON Group as of April 1, 2014.
As the next step in E.ON’s new business strategy, E.ON Energiaszolgáltató Kft returned its license to provide universal gas service to households. As of January 1, 2016, the universal gas service has been taken over by FŐGÁZ.
