Oh no they wont. You (as the customer) has to fit trunking, meter boards etc where needed ie, a block of flats. None of this needed on a single supply.
The mounting heights for their equipment (cutout, meters, time-switches, Ryfield etc is, maximum 1800mm and Minimum 450mm.
The space needed for the metering equipment is 350W, 320H & 300D. Although some paperwork from the old Seeboard area (South London) now allows you to stack the time-switch and meter. You could take a chance on not allowing space for a time-switch (for off peak etc) but you only need a jobsworth ( and EDF around here seem to employ all of them) to not connect. 150mm trunking is asked for if 3 phase ( We recently found out you can not get 27 16mm 6491x in a 100mm trunking (9 flats, live, neutral and earth) If its 3 phase and keymeters are fitted , the head and/or Ryfield have to be separately locked away.
