The disadvantage with having it at the house end is that when your angle

Switching my welder on occasionally trips the MCB on my shed socket

very glad I used separate circuits with all protection (except for the
cable itself) locally.

In which case, it's also worth designing the system to accept a type C
breaker (slightly lower L-E loop impedance required). That would help.
