This Change is in scope of June 2020 Release.

The current duplicate address validation performed within Contact Management Service (CMS) was not designed with a full understanding of IGT address management processes, particularly those associated to the new housing development market. As such, CMS restricts IGTs in their ability to keep IGT Supply Meter Point address data up to date in line with changes that are made to plans on new housing developments.

IGTs are therefore seeking to remove the duplicate validations performed on address updates, in order to ensure address changes to IGT Supply Meter Points can be made within UK Link systems, as and when housing development plans are updated.

As part of this change enduring reports and management information (MI) will need to be developed and implemented. Reports will need to provide detail of the address amendments that have resulted in a duplicate addresses being created in UK Link systems. Reports are proposed to be issued to IGTs, who in turn will be responsible to investigate and take the relevant course of action.
