Cutting a long story very short:
Energy company sent me a letter today (18 October) saying that prices are going up from 25 August, i.e. retrospectively. (+20%,+30% Gas/Elec)
I ring them to ask where I can find my meter reading for that date. Ultimately they admit that no-one knows and my charging is a 'guess'.
I have the option to leave them and have my final bill calculated at the pre-price rise rates. After some negotiation they agree to charge me the old rate until today.
They told me the regulator (OfGem) allows them up to 65 days to tell customers of price increases after they've increased!
Any one else had this? Only the (real) threat of leaving seemed to kick them into touch...
Justin.
