Manage Supply Point Registration

Customer Change Team Leader


The current processes for DCC (SMETS 2 meters) outline that a supply has to be already registered to a Supplier (and by design a Shipper too) on UK Link for the DCC to be able to register the supply in their systems and to allow communication to occur.

Currently where a site is a new connection it is being prematurely registered by Shippers to allow the Supplier to be able to complete the necessary DCC steps. This impacts charging, UIG position and also can potentially provide misinformation to the market.

Since sites are being registered onto UK Link in some cases before the property has been fully built and gas connected and are also counted in the ‘confirmed no assets’ numbers which are reviewed by PAC. A solution is required to ensure there is accurate processing and identification of where these premature registrations have occurred.

The reporting seen by PAC which contains the confirmed no assets could have an impact on UIG; the scenario described is something which has only recently been made know to PAC so could impact their decision making on next steps. PAC would also benefit from understanding what are linked to new connections and what are general no meters attached which doesn’t have the transparency it probably needs to have. 

This change proposes changes to UK Link processes only and that the DCC process remain unchanged due to expected complexity of the change to SEC and DCC systems.
