According to the Energy Ombudsman, complaints from consumers relating to their energy supplier have tripled in the past year.
The main cause behind the complaints was a lack of bills, disputed charges and inaccurate meter readings.
Official figures from the Ombudsman reveal an average of 3,500 complaints per month in 2014, with more than 5,100 in November.
Customer service issues
Speaking on the issue, Chief Ombudsman Lewis Shand Smith said: “While November’s figures show consumers are increasingly willing to escalate complaints when they feel they have been wronged, it is encouraging to see a drop in the number of problems relating to transfers and sales.”
Asked for a comment, Energy UK, the trade association for the energy industry, told the Daily Mail: “Improving customer service is key.”
uSwitch’s recent Energy Awards saw small suppliers OVO Energy and First Utility come first and second in terms of overall customer satisfaction.
General Election pledges
The news comes in the run up to the 2015 General Election, which has seen energy costs take up a central role.
Labour Leader Ed Miliband has pledged to freeze energy prices for 20 months. This promise has been criticized by many in the industry who feel it will scare off much needed investment. It has also been cited as one of the possible reasons why energy companies have not dropped prices in line with falling wholesale costs.
The Government reacted to Labour’s pledge by cutting £50 from the average energy bill, by reducing the green levies paid by energy suppliers.
