About the BSC change process

The Balancing and Settlement Code (BSC) Change process is used to introduce changes to the BSC arrangements in response to any concerns, problems or defects that Parties may identify in the current processes. Under these processes, changes can be made to the BSC, its Code Subsidiary Documents (CSDs) and to BSC Systems.

Latest Changes

  • Change Register – published every Friday as an up-to-date high level overview of all active and closed Changes, (Modifications, Change Proposals and Issues), BSS Release Summary, the Participant Impact Matrix and Change Proposal Impact Assessment Timetable.
  • Change Proposal Circulars – published monthly when communicating Change Proposals for Industry Participant Impact Assessment responses.

List of Changes

  • Modifications – these are raised to introduce changes that would alter any part of the BSC legal text. Any CSDs or BSC Systems impacted by the proposed changes would also be updated as part of the Modification.
  • Change Proposals – these are detailed proposals which are raised to amend CSDs and/or BSC Systems, but would not alter the BSC legal text itself.
  • Issues – these are problems or potential issues with the current arrangements whereby the solution is unknown or undefined, so once raised will be discussed by an industry expert Issue Group to consider possible solutions.


The Releases process is part of the BSC change procedure and includes information about where changes are being introduced, how they impact on certain areas of the industry and whether your systems will need to undergo tests to ensure they are up-to-date and meet required standards.

Getting involved

If you are interested in raising a Change, joining a Workgroup or Issue Group, responding to a Consultation or have any Change-related queries, please email the Change Team, where we will be happy to help.

Change Workgroups

The BSC Panel will establish a Modification Workgroup when a Modification Proposal is submitted to an Assessment Procedure.

Keeping up to date

We issue email notifications to the industry to provide information on Modifications, Change Proposals, Issues and Releases. This includes information on new Changes being raised, consultations being issued and decisions being made.

If you would like to be on the distribution list to receive these notifications on Modifications, Change Proposals and Issues, please email the Change Team.
