And then there was one. After Eon announced on Tuesday that it would increase electricity prices by 9 per cent and gas prices by 3 per cent, that leaves only EDF of the big six who have frozen charges over the winter.
The row that has followed runs along the same lines as that which came after British Gas made a similar announcement last year. The company says wholesale energy prices have risen, but won’t go into detail about their purchasing agreements.
Consumer groups and some analysts argue that companies can and should be more flexible with their supplier agreements to take advantage of low prices when they can. They also say that companies are more reluctant to lower prices when wholesale prices fall than they are to raise them when they rise.
It seems consumers’ best chance of being certain they are getting a fair deal is to hope for decisive action from Ofgem when the regulator announces the results of its probe into energy prices.
There have already been some noises off between the UK government and the green energy industry over the green investment bank, the government’s proposed investment vehicle for funding clean energy projects. Apart from anything, many in the sector simply don’t think the £1bn promised by Chris Huhne, the energy secretary, is enough.
But another faultline opened up today at a briefing attended by both Sam Laidlaw, the chief executive of Centrica (pictured), and Huhne himself. Specifically, the pair seemed to be at odds over whether the green investment bank could be used to fund energy efficiency initiatives.
British Gas customers brace yourselves. From December 10 you will have to pay an average of £53 extra a year for gas and £29 extra for electricity.
But given this global gas glut that we keep hearing about, the question is why are prices about to rise?
The answer BG gives is that whatever is happening on the global scale, they are paying more now than they were last year for wholesale gas – 25 per cent more in fact. They are also paying more for extra costs like transportation and other overheads.
