Licensed Distribution System Operator (LDSO)

To become an LDSO the following processes must be undertaken:

To operate as a LDSO, registration must be co-ordinated in the Central Registration System (CRS) via BSCP65 and in Market Domain Data (MDD) via BSCP509. It is also necessary to contact Gemserv to ensure all requirements for Market Entry are addressed and to contact Ofgem regarding Distribution Licence arrangements.

In addition, as an LDSO you are required to provide a Supplier Meter Registration Service (SMRS). Details on this are available from the SVA Party Agents (including SMRA) section.

Please refer to the PDF Icon Simple Guide to Market Entry(104Kb) before beginning any of the Market Entry processes.

Additional recommended reading and the forms associated with operating in the market as an LDSO are available from the tables below.
