@colin you are overthinking things.
The main one that concerns me, is the lack of main bonding present to the water pipe. This would have been noted on the EICR as observation C2 – The lack of reliable earthing is potentially dangerous, which could worsen and lead to an electrical shock risk overtime, requiring urgent remidial action. However the water bond maybe in place but you can’t see where it is connected.
Since 2020 landlords are required to carry out a EICR at no more than 5 years or change of tennant. Previously it was every 10 or change of tennant. Landlords are required to give tennants a copy….
The main cut-out fuse – Ohme will put MCB/Fuse ratings (A) into their guess o meter and if the maximimum demand is equal to or greater than 60A they will contact the DNO, not you so don’t worry.
The installers will connect the charger from your meter cupboard. This is normally in a front room or in the hallway.
