Data Cleanse Plan
Data Cleanse Plan
The purpose of the Data Cleanse Plan is to set out the data improvement activities that Programme participants need to undertake, to ensure that data is of the required quality and completeness before the cutover to the new arrangements at M10 and the start of migration at M11.
On Friday 9 August 2024, an updated v3.0 of the Data Cleanse Plan was approved, which you can view below:
Updates to the previous v2.1 of the Data Cleanse Plan, which was approved on 4 June 2024, were required to adjust the timings of some of the activities based on testing carried out by participants and the Programme.
The Data Cleanse Working Group (DCWG) oversee the data improvement activities set out within the Data Cleanse Plan.

Data Cleanse Plan Supplier Exception Resolution Declaration Requirements
The Programme has also provided templates for Suppliers to complete and share the required information as part of their declarations, as well as an FAQ document covering both exception resolution activities. You can view these documents below:

ESME ID and Meter Location & Number of Displayed Register Digits Exception Resolution FAQs
The minimum expectation is that all exceptions raised by Licensed Distribution System Operators (LDSOs) have been reviewed by Suppliers, and where the Supplier is able to resolve the issue, they have done so or have set out a clear plan to do so. If resolution is not possible, Suppliers are expected to provide an explanation for why they have not been able to resolve the exceptions raised to them.
