This is more like the helpful advice I needed, it does sound utterly complicated though, I thought the future was electric but it seems its nothing but a ball ache. If an electrician cant fit a simple car charger without reams of red tape then who can? Lets be honest its no harder to connect up than the roller shutter we did last year for him.Have you read through this, regarding the DNO side of things?
At first glance, I'd assume your scenario to be an "apply to connect" not a "connect and notify".
Plan for CT clamps on each phase. Plan for upstream RCD protection that disconnects all live conductors. Plan for wired ethernet or reliable wifi.
Also at first glance that job looks and sounds like a PITA and I'd either want enough money for time and materials to do it right, or I'd simply pass ('I haven't done the training').
Finally that charger only has a 1m hard wired supply lead which would instantly put me off it as it's almost bound to need a joint box in the supply cable.
As for the massively complicated flow chart, apart from the "iON" name not seeming to be on the database everything else seems to comply but I'll bet there are hundreds if not thousands of chargers connect to the grid without any sort of paperwork whatsoever.
As for connecting it to the SPD MCB unless it presents some sort of danger then I'm nit really interested in any technical breach and I cant see how any sort of danger can arise from doing it that was to be honest. Also the lead length, I was going to put an enclosure/small CU back to back with the charger big enough for a 4 pole RCD to fit in and do the connection there. If it doesn't need an RCD it can have a 4 pole main switch in it.
PS: What on earth is CoP, more corporate blue sky office speak?
