Correct cable for 46kVA two phase supply

My layperson guesstimate is that 16mm2 SWA cable will do the job. Open to education.

Distances are 37 m from mains cable to new backland dwelling. Up to 25m of that can be cable provided by SSE within their connection price. 

That leaves about 15m or less of SWA cable to reach the new dwelling.

OR (if the meter box is located near the mains cable) about 37m to reach the new dwelling.

 

Question:

3 or 4 or 5 core SWA cable for the bit from the meter box to the dwelling?

 

One option is to have the EV charging near the meter box and run a more modest domestic supply cable to the dwelling.
