@Mickc Sounds pretty straightforward. They may need access under the floor, a hatch should be in front of the CU. As long as there is enough room on the board to fit the EV CU, or wherever it’s gonna be located. It.ll be good. The sparks will address any problems onsite, doesnt look like any show stoppers.
They will have a job on going under the floor its solid concrete. Looks like the concensus is get it fitted.
I bet Ohmes consensus would be trunking rather than lifting boards up and charging a fortune for it!
You will be ok Mick 🙂
