CP1320 – Replacement of erroneous Change of Supplier Readings

Formal title: Replacement of erroneous Change of Supplier Readings

Current Status

CPC Consultation
Committee Decision


Elexon held two working groups to consider clarification of the use of Gross Volume Correction (GVC) and guidance (GVC Guidance) on the retrospective correction of errors. The group recommended that clarifications should be made, both in terms of when the Change of Supplier (CoS) reading could be replaced and the method used to agree and carry out the replacement. CP1320 proposes to add clarity to BSCP504 to the effect that a CoS reading can be disputed no later than 12 months after the Supply Start Date (SSD).


CP1320 was raised on 27 November 2009. CP1320 was issued for Industry Impact Assessment as part of CPC00673. At its meeting on 2 February, the SVG rejected CP1320.
