Energy Big Six worst for complaints

THE Big Six energy firms are all in the bottom ten of an annual customer satisfaction survey as consumers turn to medium and small suppliers.

However, some small suppliers are showing signs of growing pains with Extra Energy and Spark Energy joining Npower at the bottom of the Which? survey. Utility Warehouse, Flow Energy, Octopus Energy, PFP Energy and Utilita were the top five.

Of the Big Six apart from Npower, Scottish Power and British Gas were joint 26th, SSE 24th, and EDF and E.ON joint 22nd. Only 32 per cent of Big Six customers are very satisfied on average.
