Customer Change Team Leader


This Change is in scope of June 2020 Release.

This change has two elements and ultimately aims to improve communications with end consumers during planned and unplanned gas supply disruptions.  

The first element involves the implementation of a process by which customer contact details will be provided to the CDSP by Suppliers. The process will be developed by a SPAA working group set up to progress SPAA SCP 443 – Notification of customer contact telephone numbers to Transporters.

The process of getting the customer contact details could involve Shippers and be via the IX within a UK Link file format(s).  Please note, other solutions are also possible.

The second element of the change involves the provision of a web portal to allow GDNs and IGTs to send messages to selected customers.

Impacted Customer Types

  • IGT
  • Shipper
  • DNO
