I will be getting a new car soon, its going to be an Electric Vehicle.
I can get a free PODPoint installed, this requires a 32a supply.
My house is on a modern estate (12 years old), with the garage adjoining a couple of others in a shared car park (for 4 cars) at the end of my garden.
The garage currently has a 16a supply via SWA, fed from the main Consumer unit in the house. A small consumer unit in the garage supplies a couple of 13a sockets and a lighting circuit.
The existing cable will not be suitable to run an additional 32a EV charging point from, so I accept I will need to run a new SWA cable to the garage.
As the main electricity meter is along the side of the house, the easiest and shortest route to the garage is from that box, rather than going right back to the consumer unit on the opposite side of the house. I already have a 100a main supply fuse and PME earthing.
With this in mind, I have installed 2 henley blocks, ready for when the Smart Meter Engineer installs the meter on Friday. I will ask him kindly to fit the existing tails into the blocks and run new short tails to the incoming supply. This will make it very simple to add an extra supply for the garage.
Onto my questions:-
The charge point will probably be mounted inside the garage as there isn't really a suitable wall outside to mount it on. However, the vehicle will remain outside when being charged (cable run under the garage door)
I'm just trying to budget and plan as much as possible in advance.
Thanks for advice and suggestions

Onto my questions:-
- What sort of breaker should be fitted between the henley blocks and the new garage SWA cable?
- Should I plan to keep the existing garage consumer unit (It is already a metal unit with RCD etc) in place on the existing SWA cable and install a 2nd unit, on the new SWA? or instead cap off this supply and put a new larger consumer unit in with capacity for each of the existing garage circuits plus a spare 32a for the EV charger?
- Based on the answer to (2), continue using house PME, or should the garage become TT isolated and have a local earth rod?
