My questions are:
(a) can OVO legitimately change the readings submitted by me?
(b) when. or if, will OVO start to bill me for gas?
(c) will I lose the dual fuel discount?
(d) can I contact OVO without losing my self-service reward?

This doesn't sound right to me.... when my meter was swapped the next bill looked like this
So the billing system is obviously capable of coping with this scenario. You can see that there are actually two entries, one for the old meter and one for the new and that the MSN has changed. MSN is the serial number for the meter I believe. The MPAN (Electricity) and MPRN (Gas) should stay the same I think.
I also remember then when my meter was swapped the installer was very keen to take pictures on his camera phone of the old meter/readings, he said he has to provide photo evidence to OVO, so hopefully there is a record somewhere.
Maybe time to get in touch with them?
