CP1256 – Action on Backdated D0052 Flows

Formal title: Action on Backdated D0052 Flows

Current Status

CPC Consultation
Committee Decision
Awaiting Implementation


On occasions it may be necessary for Suppliers or UMSOs to issue D0052 ‘Affirmation of Metering System Settlement Details’ to NHHDCs with backdated Effective From dates in order to correct previously-provided data. It is not clear from the current documentation how such D0052s should be processed by NHHDCs, and in particular, whether the data on the new flow should overwrite all previous data provided via the D0052 or only that which is in place up to the next Effective From date.
