    A CNE can be used in an installation (with certain exceptions), unless prohibited by ESQCR. For installations that take an LV supply from the DNO, combined neutral and earth is usually prohibited by ESQCR downstream of the distributor's equipment - see Regulation 8(4). This is also why, even in installations with private transformers and PNB type arrangement, effectively the only bits of TN-C are effectively the transformers / generators themselves.
