Meter position 50m from dwellings?

[BillyH]

Client wants DNO to establish a service head for 6meter positions in a purpose built building for a barn conversion complex. Some of the dwellings will be in excess of 50 metres so csa would be larger than 25 mm. Assuming Core size of 50 mm , what would be the best way of terminating at each end?

Adaptable boxes seems best , 100A switch fuse at meter position ,
