E.ON must pay £7m over smart meter delays

Ofgem says that business customers lost out on receiving better information about their energy consumption

E.ON has been told to pay 7m to the Carbon Trust for its "unacceptable" failure to supply enough advanced smart meters to business customers, regulator Ofgem has revealed.

The energy giant will also face a sales ban and a further 7m redress if fails to meet its new interim targets.
