How are your Supplier Charges calculated?
G15 – CM Supplier Payments provides information on how Supplier Charges are calculated. Unlike the Settlements Costs Levy, the Supplier Charge and Credit Cover requirements will vary from month to month as a monthly weighting factor is applied. As a result, Supplier Charges and Credit Cover requirements will be higher over winter months compared to the summer months.
To view the weighting factors applicable to the 2025/26 Delivery Year, please view our Settlement Data webpage and select the monthly weighting factors drop down. Also, the Stakeholder Support for Supplier CM provides supporting information.
