BSC Procedures (BSCPs)
BSCPs define the relationships, timescales and interactions between participants and specify the information or other outputs to be exchanged between them. BSCP forms contact details web page will give you information for all Agent/Administrator contact details for which you should send BSCP forms. The latest conformed versions of BSCPs awaiting implementation are available on the Changes Awaiting Implementation page.
