Ofgem has opened an investigation to establish whether E.ON is complying with its obligations on energy sales.

The investigation is being launched following information which has come to Ofgem’s attention regarding E.ON’s marketing activities.

In 2009 and 2010, Ofgem strengthened suppliers’ obligations relating to energy sales. The changes set out that suppliers are required to put in place robust processes to guard against mis-selling.

These obligations include ensuring that any marketing material that suppliers use and information that they provide during telesales and face-to-face marketing are fair, accurate, easy to understand and do not relate to products that are inappropriate for the customer.

In addition, suppliers are required to conduct any telesales and face-to-face marketing activities in a fair, transparent, appropriate and professional manner.

Ofgem is continuing its investigations into the energy sales practices of Scottish Power, SSE and npower and has recently concluded an investigation into EDF Energy on this issue.
