A spokesperson for Ofgem said:

“Ofgem has been at the forefront of making the energy market more transparent for consumers over the past few years. One of the ways we do this is by publishing weekly updates on our website which estimate the costs and margins for supplying a typical customer of a large energy company. Obviously the costs of an individual supplier will vary and it is up to them to explain their own costs, margins and pricing decisions to their customers. In particular companies will buy their power and gas at different times and different prices on the wholesale market. In publishing these figures Ofgem is giving consumers greater understanding of the relationship between energy bills, wholesale energy prices and the other costs that make up energy bills.  

“Our own weekly monitoring published on our website estimates that, over the last year, the cost of wholesale gas and electricity to serve a typical dual fuel customer would have risen by around £10 to £610. However, this figure could be higher depending on the hedging strategy of an individual company for buying gas and power in forward markets. We have also published actual market data which shows that the wholesale price of gas for use this winter is 8 per cent higher than the price of gas for use last winter. The wholesale price of electricity for use this winter is also 13 per cent higher than the price of electricity for use last winter. The actual increase in prices for an individual company will depend on their particular circumstances.”
