Scott,
I wondered if it was how many units you each profile during the summer months.This might have an effect on how many units each model attributes to 1st and 2nd tier Units.Then as you say there is the complication of the discount on 2nd tier electrcity units.There must be, however,quite a difference in assumptions to throw up such a significant difference.It's more than 5% and makes the difference between choice of supplier.
The tariff structure on Click Energy 6 is, as you say, overly complicated.If you lot are struggling with it,how is Joe Public expected to understand and check billing when it comes? Once again, BG do not do themselves any favours.I have to say,our 'Regulatory friends' should get a grip of this sort of thing before new tariffs are accepted.
Furthermore,there should be an automatic switch of Click Energy 5 customers to Click Energy 6,where it is cheaper and undoubtedly it is.However,BG just let you sit on an old tariff till you push for a change.
Immoral !!
If we stay with BG, will they backdate the Click 6 prices to their tariff change date ?
Thanks for looking into this, but as illustrated, we can't have accredited organisations coming up with such diverse results.
