That's a load of ********! this is the exact working of G87:
Building Network Operator (BNO)
The organisation that owns or operates the electricity distribution network within a Multiple
Occupancy Building, between the Intake Position and Customers’ Installations.
The BNO may be the DNO, another licensed distributor or a third party exempt from holding
an electricity distribution licence (e.g. a facilities management company).
Broadly speaking, either:
a) A licensed distributor may offer to adopt the Building Network, if they so desire and
the assets meet the reasonable minimum standards of that licensee. In such cases
the Building Network should be considered as an extension of that licensee’s
distribution network and part of the licensed distribution business; or
b) The Building Network would be licence exempt and therefore generally treated by the
DNO as any other Customer’s Installation, subject to the detailed provisions of this
EREC.
