But having an EVSE already installed could be a selling point.Oh, well, then discard it if you don't want it. Just I mean that someone capable of installing one, is capable of uninstalling one, so building regs approval is pretty irrelevant.
And you can't just remove the box and leave the cable and CU equipment. It's still a circuit and it's the circuit that requires Building Control notification.
Personally, if someone told me that the owner was going to rip out a complete power circuit before handing the house over to me I'd be wondering what else might go on. It's cheapskating.
