You are simply amplifying some rounding errors (which may or may not apply in reality).
Look at the non-vat rate. e.g. 13.36p plus VAT is 14.028p (which has been rounded to 14.03p)


If the case of electricity you are talking of a difference of 22p based on a £500k bill.

You've amplified the gas bill to over £1m - you can't have this tariff with that type of consumption.

However, even using your figures it shows you are never worse off on a nsc compared to a sc tariff, no matter what extremes you take it to. So why ever choose a sc tariff? Point proven?

(strangely, the nsc gas tier 2 rate is very slightly less than the standard unit price of the sc tariff as well and the maximum premium, ex vat, of tier 1 is just £11.43 compared to the sc of £12.191 per quarter)

Yes, you are correct about the VAT. I should have used the non-VAT rates and only calculated the VAT at the end. I've got a spreadsheet now so will tweak it to do that.

However, I think that what I have shown is that you're never worse off with a NSC tariff (with that particular supplier anyway), which is all I was wanting to show.

The only reason I did the massive inflation of the usage was to see if the formula ever broke down at some point! I don't actually expect you'd get that tariff with that sort of usage!
