Thanks for the PM about this, unfortunately I am not the one installing the charge point, I am however on the Government Approved Installer list and went through the 3 month rigmarole to get approved.
I have only been asked to put a suitable 32A metered supply in near the intake so that they can connect a 6mm circuit to it.
Personally I would just put a 6mm circuit in to a Rolec unit with built in meter, but they are not installing a rolec unit.
