What earthing system is this ?

[caffreys]

I'm was a bit confused by this photo initially as I couldn't see how the DB was connected.

DB is above the incomer - you can see the tails just behind the board

Yes I realise that, just initially when I looked at it the tails looked like they were going into the bottom of the cut out!

I wonder if that one disappearing down the conduit, might go down and out to an earth rod?

That is certainly one possibility, and it's what I read as being the implication of the question asked by sparkwright at the start (post #2).

Kind Regards, John

63 Amp should be okay as it'll be charged using the 3 pin granny charger on a 2.5mm radial with one socket and a 20amp rcbo (It's the single external socket on the property)
Also charging will be done when there's almost zero load

Might contact the DNO to see if I can get a 80 amp upgrade

I'm not planning on a EV socket installation, I believe a lot of those need an earth rod?

Things are changing all the time see BS7671 amendment 1

The initial charging units did need an Earth Rod, though more recently many have a device that monitors the Presence of the Neutral and has relays that cut off the Supply in the event of it being Lost.
