Yup, indeed its probably the same address that triggers that something is amiss on the Ohme system.
The Motability sales person had suggested that Ohme had previously deleted the installation with a cancelled order and a new order, as it had happened to a previous customer of theirs. It seems that Ohme had deleted both.
When waiting on the Ohne fitment, I received an email from Ohme telling me the charger was going to be fitted next week, but the postcode was for an address 200 miles away, probably the Ohme order number had a couple of transposed numbers. Probably A clerical error by Ohme.
It is a minefield dealing with Ohme.
Then again, most installs are quick and painless. Its the complicated ones where Ohme falls short.
