Energy regulator concerned that a slump in wholesale gas and electricity prices over the summer is not being passed on
Ofgem, the energy watchdog, is launching a renewed transparency drive over the finances of the big six energy suppliers amid further concerns of profiteering.
Figures released by Ofgem show the companies that dominate power generation and supply have had combined earnings before interest and tax of almost £17bn over the past five years. It is demanding independent auditing of annual accounts broken down into individual divisions as well as the faster release of figures and more details on corporate cost structures.
