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.

The Programme is taking the updated Plan to the Migration & Cutover Advisory Group (MCAG) on Tuesday 22 July 2025.

You can view clean and red-lined version 4.2 of the Data Cleanse Plan below:

Upcoming Activities  

Meter Location and Number of Displayed Register Digits

Suppliers are expected to resolve all outstanding exceptions by Friday 18 July 2025

The Programme has provided a template for Suppliers to complete on a monthly basis, documenting the number of resolved and unresolved exceptions, as well as an FAQ document covering both exception resolution activities. You can view these documents below::

Exceptions Count - ESME ID & Meter Location and Number of Displayed Register Digits

ESME ID and Meter Location & Number of Displayed Register Digits Exception Resolution FAQs

The minimum expectation is that all exceptions raised by LDSOs have been reviewed by Suppliers, and where the Supplier can 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.
