Hey Niek,
The workshop was without power when I took it over as a barn, I had to pay for the UK power network people to make a connection to a box just inside our land and then run a cable the 110 metres to the barn!! You can see the green box behind the gate, this connects via a trench to the cable in the street.
This was around ?5,500 to have a 3-phase connection to the green box. However the cable up to the workshop is just single phase so all my stuff is single phase but I could upgrade to 3-phase in the future if need be. Luckily the land owners are solid so we spilt the power connection costs in half.
The lathe is about to get an upgrade to a VF drive so I can control the speed, if that works out I'll do the same to the mill as belt changes on the mill are a pain in the ass!!!
