Codes of Practice

Codes of Practice (CoPs) detail the technical requirements for Metering Systems. These versions are not time limited in the same way as other documents.

When Metering Equipment is first registered in Settlement, it must comply with the requirements which are set out in the relevant Code of Practice in place at that time.
