I could be wrong here - but I've never come across any law in the UK that prevents a private non-goods vehicle from being driven on the roads if it's over it's manufacturers specified fully-laden kerb-weight?
I've an old colleague who drives a retired ambulance around - modified by its conversion from van to ambulance with around 3 tonnes of extra auxiliary batteries, hydraulics, oxygen tanks and ballast weight. There's no law stopping him from driving that!
Only restrictions on weight I can imagine are driving an overweight vehicle on weak roads where specified - or where the vehicle's being used as a goods vehicle. If you're trying to convert an HGV or a van that will be used for commercial purposes, then you may have a point - but a private vehicle for personal use only isn't going to tick that box.
My understanding of the process of getting an EV conversion on the road in the UK is quite simple, declare the change of fuel type to the DVLA, get it to pass an MOT, tax and insure it like normal. (albeit you may need to go to a specialist insurer as mainstream ones might not accept an EV conversion).
What's the vehicle you want to convert? You might be surprised how little extra weight it might add if you are converting a small car where the engine to be removed takes up a larger proportion of the vehicles weight in the first place.
