EDF and SSE have ranked the best in the National Customer Satisfaction Index (NCSI) of the major energy suppliers in the UK.
EDF’s satisfaction rating rose from 65% last year, to 71% in 2013.
SSE also received a 71% satisfaction rating, although theirs has fallen slightly from 73% last year.
Martin Lawrence, managing director at EDF Energy, said: “We are determined to give customers the excellent service they expect and we have worked hard to improve our performance.
“We admitted that our service fell below the standard customers deserve following the introduction of a new customer service system two years ago. This result shows the huge improvement we have made.”
At the bottom of the NCSI table was Npower, which had a rating of 63 per cent, which fell from 68 per cent last year.
A spokesperson from Npower said: “We’re disappointed by these results. Our customers – and the level of service we can provide – are our number one priority and that’s why we invested over £200 million in a new customer service system.
“We’ve just finished moving nearly six million customer accounts to the system, which will ultimately allow us to respond to customer queries quickly and more efficiently.”
