SIX energy firm Npower once again topped the list of the most customer complaints compared to its peers, receiving ten times more complaints than SSE.
The research by the Citizens Advice bureau showed that Npower received 306 complaints for every 100,000 customers between October and December 2013, while SSE got 31 complaints per 100,000.Three times as many complaints were made about Npower than the second worst performing supplier, Scottish Power.
There were twice as many complaints about Npower by the end of 2013 compared to the start of the year.
“We wrote to all our customers during this period last year apologising for the impact on them of issues we have had with the implementation of our new billing system,” said Roger Hattam, Npower’s director of domestic business.
“We are making good progress in dealing with the root causes of this, but remain totally committed to resolving any problems this has created for our customers.”
