I am in the middle of installing a new 3 phase system for a small bakery production area, new building, 200 KVA supply in total. 200 TP for workshop plus 4 separate 60 amp single phase supplies for new flats above new workshop building. Checking with UK Power Networks they inform me that the customer is responsible for distribution from their cable end to the service cut outs. I was always under the impression that everything beyond the meter was down to UK power and the supply company. Am I wrong?
