Hi @leewilson that’s a bit of an annoying one. We asked for the reading on the 13th as the way we all work (as suppliers) is to take a reading from anywhere within 5 days of the switchover and use it as the changeover reading, since we all know that people might not necessarily be able to get to their meters on the switch date. Since the reading we open on is the same one as the old supplier have on record, it’s quite tricky to change-but since you were on prepay with them they might be happy to change your final reading over, if they hear from you asking them to change it. If they are happy to change, let us know and we’ll get in touch with them ‘officially’ to change the reading over, then you won’t have been double charged. A related note-if there was any credit left on your meter when you switched over, the old supplier is sometimes happy to refund it, if you send them a photo of the meter saying how much credit is left on there (it shouldn’t have changed since the day we took over).
