I moved houses back in late Jan 2022 and switched to OVO on 13 Feb. Previously, the flat was with EDF. OVO installed a smart meter for electricity on 4 March. There is no note of the old meter number (that meter had EDF written on it), or its readings anywhere on the OVO’s first bill - it shows only a standing charge for 13 Feb - 12 March.

I just discovered I kept getting online bills on my EDF account that I inherited when moving into the property, clocking over £120 from Feb to May (I did pay them once back in Feb and thought that was the end of the transition, but clearly it wasn’t the case).  Of course, it was my bad for not catching this much earlier, but I’ve had a lot going on with our disabled daughter and another large house move.  I got in touch with EDF and they have different MPAN to the flat compared to the one on the OVO bill (it’s different by 1 digit only, probably someone somewhere made a typo). EDF insisted that OVO got a wrong MPAN and said that my OVO account needs to be closed, and then OVO needs to apply for a transfer again.  EDF refused to give me a final bill based on the photo of the meter I have from 13 Feb (entry reading for OVO).

Now, I called OVO, and the OVO agent said to check with UK power networks and confirmed that the MPAN OVO has is a correct MPAN. So apparently, EDF had a wrong MPAN all along, but the correct meter (old meter serial number is shown correctly on the EDF bill). So OVO agent said that as they have the correct MPAN, the problem is with EDF, and there is no case for closing  my account and then doing the transfer again. ( Neither would I want that) 

Called  back to EDF and they said that as the old meter number is nowhere in OVO bills and the final reading of that old meter was not recorded by OVO, OVO would need to submit for erroneous transfer. EDF refused to update my  bill based on the photo of the old meeter I had on the transfer date in order for me to pay it and close the account with EDF.

Now, I’m 99% sure that when I call OVO tomorrow, there is no way they would file for erroneous transfer. I’d like to stay with OVO, without any interruptions in my account, but I don’t want to keep paying to both EDF and OVO. 

So what do I do? Is there an adjudicator between networks?  Can I just insist on my final meter reading with EDF and plain refuse their assertion that I still have an account with them? I am completely lost in this. Please help.
