Energy giant npower has continued to receive the highest number of complaints, with a 25% rise in the number of unhappy customers.
New statistics from Consumer Futures show the supplier received 253 complaints per 100,000 customers between July and September, up from 203 the previous quarter.
The figure was eight times more than complaints recorded by SSE, the best out of the Big Six suppliers, which only received 32 per 100,000 customers. It was followed by ScottishPower (46), British Gas (55), E.ON (62) and EDF Energy (74).
npower was also the most complained-about energy firm in the previous survey between April and June, blaming the low performance on a new computer system.
Audrey Gallacher, Director of Energy at Consumer Futures said: “While npower has acknowledged and apologised for its poor billing systems and agreed to pay vulnerable customers who have been disadvantaged, its deterioration in performance is still wholly unacceptable and the company must address the failure of its systems, processes and customer service to put things right.”
