I cannot take my next reading in one months time as I am away from home. I could do so a week or two weeks later. What are the implications?
I asked a similar question quite recently, please see https://community.bulb.co.uk/discussion/4311/monthly-readings-holidays-etc/p1
If you are unable to provide a reading an estimate will be made. If you submit a reading a week or two weeks later then this will be taken into account for the following months bill (i.e. it will self correct itself) .
@shanthi we’ve got your starting readings, so everything’s A-OK on that front. Don’t worry about strictly sending us a reading once every month - we find that a reading once every 3 months is enough to keep our estimations accurate as well.
