The number of complaints received by energy suppliers has risen, according to an article published by the Telegraph.
Each company is obligated - under Ofgem regulations - to publish their customer complaints data - with the figures for some companies showing a considerable rise.
The numbers of complaints received by members of the so-called "big six" firms has risen - with EDF seeing the amount of complaints it received rise by 40 per cent for the year-long period leading up to September.
Consumer Focus have come out and criticised the current system, arguing that the data provided by some companies is unreliable.
A spokesperson commented: "Consumers need more information about complaints handling - but this must be meaningful and representative. These figures have not been checked or standardised and they only show complaints not resolved within one working day."
Finishing, the spokesperson added: "It is therefore difficult to tell how accurate a picture of overall energy complaints they present."
