It looks to me that wholesale prices for both gas & electricity are now similar to what they were in spring last year. And 30%+ cheaper than they were in September. So there must be more to it than just wholesale cost. Perhaps, I’m wrong, I don’t really understand all this.
I don’t understand it either. Wholesale price in Feb for next winter (2019/20) were 1.6p, and it’s now 2p. So an increase of 0.4p. But our price has gone up by 1.2p. So can only assume network costs have gone up massively, or all the suppliers are making more margin. With so many small suppliers going bust, they can’t be. So in other words, I have no idea!
