Energy Minister Michael Fallon said:
“I have rarely seen a worse case of consumers being misled so badly.
“With rising energy prices, and multiple tariffs to contend with, consumers deserve the clearest, fairest and best possible deal.
“The Government is already acting through the Energy Bill to give Ofgem the teeth it needs in future to get compensation to those directly affected.
“And we’re using new legislation to require suppliers to simplify their tariffs and get rid of historic poor deals.”
