Since your statement day is on a fixed date in the month, PP need to charge you for the amount of energy you've used by that date.
(If they didn't do that your statements would be all over the place, for example you could submit a reading on the first day of your month and if PP didn't charge for the rest of the month your statement would show almost no energy charges)
You can submit readings whenever you like (once a day).
When you submit a reading any time during the billing month, the amount of energy you would use after
you've submitted and up to the next statement date
has to be estimated because PP don't have a submitted reading for those days (unless you were to submit another reading nearer the end of your month)
Both the reading you've submitted AND the estimate for the rest of the month will appear on the statement.
So, if you submit as near to the statement date as possible the more accurate the statement will be. (as the fewer days will need to be estimated). I usually submit mine the day before the statement date to be on the safe side, BUT it doesn't really matter because the next statement will always correct itself when the next month's reading is sent.
Does that make sense or have I just confused you? It's a bit of a pain to explain it succinctly.
