How to prepare for electric charging point?

[CalvinHobbes]

Unsure which section to post this in but the digger is there, everything is getting levelled. Trenches for electrics, drainage going in but I want to add one for charging an electric car. Should I put in the actual cable or would it be better to do just underground ducting?? Also if you tell me cable, which kind? Thanks

Feed the cable through the duct before laying would be my choice.  Just makes life easier all round, one less thing to do another time.  Cant comment on the size of the cable unfortunately.

Duct with a rope through 100%.

Thanks, I think thats a great idea with possibly 2 ropes considering I might need a separate data cable. As I understand it the new chargers have to be smart. 

I saw this but have already been told go for cat 8 and which can use cat 7 or 6 end points. I would like to be able to charge the car at minimum 22kwh but considering we will have single phase not sure if thats poss.

Rope in the ducting is the best way. I have a few long lengths of ducting with rope buried around the plot in readiness. Getting the rope through a long bit of ducting can be a challenge though. In my case I used the slope, gravity, and a socket. Tie it off at either end to a bit of wood. I used the cut up plastic advertising board that was advertising our plot for sale which was oddly satisfying. 
 

That combined data and power cable looks good. You could always phone an installer and ask them what they’d need. 
 

When it comes to electrical ducting my view is to put in more than you think you’ll need. Much harder to do it afterwards.
