Ohme could and should send out an engineer to do a site survey if you cannot do this yourself.
Until your property is surveyed by a professional, you are just guessing.
My meter box is inside wall in the hallway on the gable next to the drive. All the electrics are 2 m from the front of the property.
I completed the Ohme survey early July and have a provisional date of February for installing the chargepoint.
I have complained twice to Motability, and the complaints go into a deep well, never to be seen again.
