Prepay Meter: Why does the meter deduct additional charges?

I have just made the switch to yourselves and am concerned that when we top up presently that our meter deducts additional charges , can this be checked so we have peace of mind moving forward ?

I have no experience of a prepayment meter but my understanding is that each day an element of your top up will be used to pay the standing charge.

@ShaunT A prepayment meter will take the standing charge for the number of days since the previous top up. Would it make sense if these additional charges were because of this? Let me know if it seems to be another error and we can look into it.

Thanks dan. Would this show up as debt when deducted ?
