Data from the Citizens Advice Bureau shows that most complaints received about UK energy firms relate to two of the smaller, “challenger” brands – Extra Energy and Co-Operative Energy. The only big six firms to appear in the bottom 10 of the league table, behind Extra Energy and Co-operative Energy, were Scottish Power and Npower, which have both battled billing issues caused by IT system upgrades. The average number of complaints per year for these companies is around 1,500. The only big six firms to appear in the bottom ten of the league table, behind Extra Energy and Co-operative Energy, were Scottish Power and Npower, which have both faced billing issues caused by IT system upgrades. SSE, which laid claim to the lowest complaint rate in the industry since the table was first published five years ago, was narrowly beaten to the top position by EDF Energy.
