Change Proposal Circulars

We publish Change Proposal Circulars (CPCs) when communicating BSCCo change information, and in particular when requesting Impact Assessment responses to Change Proposals and Draft Change Proposals from Industry Participants (BCAs and PACAs).

The Responses column describes the deadline for responses and includes the response document, in PDF format, where applicable.

The table below shows the latest Change Proposals Circulars
