As Kezo says, as soon as you place an order for an EV, you are contacted within a handful of days by Ohme, who have a link with a form to fill in.
Its as simple as that. If you are unable to fill in the form, they will send an engineer out to carry out the survey.
It is nothing to get stressed about, uncertainty is a worry.
IF your property is NOT suitable for a chargepoint, you can cancel your order for an EV.
But the installation of the chargepoint will more than likely go ahead without any problems at all. A few do have problems very many do not
If you go ahead and order your EV, it should all be seamless. Its not a thing to worry about.
