Whatever happens, in the end you can't be charged for the same units twice.
The closing readings on SP even if disputed must match the opening readings on PP
Thus any difference is merely the difference in unit prices, and is usually very small.
Also there is a tolerance allowed below which you can't dispute, I believe it's 250kWh for E and 109 cu.m for G
Does that help at all?
So for example if difference in unit price was 0.5p/unit and SP was more expensive than pp by that amount, and there was a 100kWh difference in reading (from what you think it should be, the billing difference would be 100x0.5 or 50p
If you need to query this go through help, ask wattbot, type message the team and ask.
