Ensuring the UK's largest energy companies are transparent about the way they calculate their gas and electricity tariffs will be an essential part of improving fairness in the sector.
This is according to Labour's shadow energy and climate change minister Caroline Flint, who said opening the books of providers will allow users to see for themselves whether or not they are getting a fair deal.
At the moment, a lack of transparency is leaving to many people believing they are being ripped off, she continued.
Ms Flint added: "Until the big six energy companies sell all of their energy into a pool and new companies compete to sell it to the public, we won't get the lower prices and fairer tariffs people need."
She was commenting in response to a recent report from Ofgem that called for domestic electricity and gas providers to make the way they calculate bills clearer.
