After a postcode change it seems I can't locate the MPRN from the new or old address.
https://findmysupplier.energy/ Might be very nice but it expects me to pay a premium 0870 number. Last time I was phoned National Grid the conversation took 30 minutes of wait and resolution.
I presume this is a portal into the national MPRN database. Can anyone point me in the right direction of who owns this database and a normal number to contact them to update their database?
