We’ve discovered (well @Firedog has) that if you send early on the day following it is used and not estimated
This ‘discovery’ was the result of one test on one day, so it’s hardly a recipe for guaranteed success. However, the thinking behind it was that a manual reading is recorded on the day it’s received, but when applied to bills, it’s treated as if it were entered at midnight. On the first day of the billing period, then, a reading submitted that day will be used both as the closing reading for the previous period and the opening reading for the current one. If you try this for the next billing period, please come back and tell us whether it worked or not.
[My experiment took place on a day when smart meter readings don’t make it - the first day of a quarter when tariffs change. There is just so much traffic on the smart meter network that day with every smart meter in the country having to be updated that there’s just not the bandwidth available for readings to get through to suppliers.]
We’ll always bill you to a reading the day before the billing date. For example, if your billing date is the 25th of each month, we will bill from an opening read on the 25th of the month to a closing read on the 24th. In this case, the best time to give a read would be the 24th. if we don’t receive a reading that day, then an estimate will be generated based upon your previous actual readings.
We'd recommend having smart meters installed, as then you won’t need to submit reads, and won’t be billed to estimates.
