Ofgem has said customer service across energy retailers is “just not good enough” after its latest review of the sector found failings at all 17 suppliers probed. It has issued Eon with a provisional order over its "very poor" standards around call waiting times and abandoned call rates but also identified 'moderate weaknesses' at 11 further suppliers. As a result of its findings, Ofgem has said it will consider “stronger, more prescriptive minimum consumer standards”.
