In December 2013, E.ON gas and electric prices were announced to be increasing by 3.7%. The energy provider stated that the change would take effect on 18 January 2014.

For the second year in a row, E.ON was the last of the big six suppliers to announce its price rise, and it was the smallest rise of its competitors. The supplier was able to integrate a government led energy bill cut due to its later announcement.

E.ON Chief Executive Tony Cocker admitted that this was unwelcome news for customers, stressing the company's effort to hold out on the rise as long as possible:

"There is no escaping the simple fact that any price rise is unwelcome news for customers. We know that, which is why we have held off for longer than most of our competitors and worked hard to keep our rise as low as possible.

"However, now more than ever, the help we offer our custoemrs, in terms of advice and practical measures, is absolutely vital."
