I think mandating a charger is going beyond their remit. Ill be fitting a dummy or spares and repairs to my next place unless we have an EV. If the bco turns up and there's one on the wall id imagine they would be happy.
Anyway what happened to the granny charger leads that could be a charging point with an outside socket
Id seriously be looking into a spares or repairs charger on ebay and fitting that to the wall. Surely he's not going to test it. Why the hell are these a mandated item on an individual build?! If you need one you will fit one. What possible reason is there for making people fit them?
Fancy planners dictating window colours on a development like that. It's hardly likely the builder would do anything crazy anyway, they want to be able to sell them. One reason of many this country is knackered some office jobsworth dictating window colours.
If your not confident marking and cutting for the underside. Just use your jigsaw with a downwards cutting blade and take your time. It won't be a perfectly straight cut but as above the edge of the sink will hide a lot
Ah I understand i had manifold in last place worked well. If your cylinder is in airing cupboard and you have a separate utility/ plant room i suppose you'd have hot manifold in ac and cold in utility/plant?
