BM Unit Transfers
How do I transfer ownership of BM Units?
If you decide to change the ownership of a BM Unit, you will either follow the Change of BM Unit Lead Party (CoBLP) process for a Central Volume Allocation (CVA) BM Unit, or a Transfer of Supplier ID for Supplier Volume Allocation (SVA) BM Units. These generally require a 30 Working Day lead time, but it won’t take as long if there aren’t any issues.
Change of BM Unit Lead Party
This process transfers a CVA BM Unit from one Party to another. All the other details with the BM Unit, such as parameters (e.g. GC/DC and CALF values), Metering Technical Details (MTDs), Aggregation Rules and Metering Dispensations, are transferred across to the new Party unchanged. However, any Metered Volume Reallocation Notifications (MVRNs) will be end-dated with the transfer, so the new Party will need to set these up again, if they wish.
Transfer of Supplier ID
This process transfers a Supplier ID from one Supplier to another. Each Supplier ID will have 14 Base BM Units attached to it, and possibly some Additional BM Units. All of these are transferred across as part of this process. If a Party transfers their last Supplier ID, then they will also need to deregister their Supplier ID.
The two processes are described in BSCP15 ‘BM Unit Registration’, which covers the procedures and timescales for transferring BM Units.
For a CoBLP, the current Lead Party needs to submit form BSCP15/4.11A, while the new Lead Party needs to submit form BSCP15/4.11B. For a Transfer of Supplier ID, the current Lead Party needs to submit form BSCP15/4.6A, while the new Lead Party needs to submit form BSCP15/4.6B.
