Complete DCA will take between 3 – 6 months Costs Options Timescales

Issues Should UK Link hold SMSO for LSPs and I&C sites? What should SMSO ID look like? Field length Compatible with electricity or unique? Should suppliers populate the SMSO field with the value DCC? Can the DCC status flag be populated for a future effective date Retrospective date Should we create a dependency between a SMETs compliant meter and IHD. (i.e. If Meter Mech Code is S1 or S2 then IHD must be populated. A recommendation has emerged from Mod 430 that Non SMETs Meters changes from a code of NSS to NS. Will security requirements from STEG place additional requirements on the solution?

Foundation Stage Issues Installing Supplier difficulties where Meter Asset Info has not been updated. Many redundant supplier IDs held against MPRNs on UK Link Consequences Incorrect Installing Supplier No facility to retrospectively change data Potentially complex and time consuming solution FIOM document 3.0 states that suppliers can derive installing supplier on DES for themselves. Data items to achieve this are not available.
