Looking back on what was needed prior my my install which was a bit of a faff A couple of pics and a quick outline of floor distance cable direction
I suppose it took 15 mins top
My biggest obstacle was trying to communicate with my DNO which entailed being passed from pillar to post across India (I kid you not I could not understand a word they said and visa versa) took me 8 days of trying days to get a call back
Looking back I should have done things differently but was unaware of how the process went
When contacting or when contacted by lets say Ohme make it clear that you are disabled and that you require a home visit so they can ascertain what is required themselves ( no sketching/measuring/photos ) any problem with this request then simply hand the reins over to motorbility
Whilst that is in motion,..in this order..update your ( bill paying )electric supplier and tell them you are to have a car charger fitted,they will arrange any upgrades needed once complete contact DNO and tell them supplier has completed their upgrade and you want DNO to now do their upgrade once done contact lets say Ohme (who should have already by now had a pre visit so will know what is required)
Hope this helps those who may be as confused as I was when trying to navigate this process
