Here, you will find the forms you need to set up or change bank details with us, to change a reactive meter, change a contact or find out about payment statements, estimates, and invoicing. Our settlements team is responsible for calculating and making payments to ancillary (balancing) service providers.
Useful template documents
Use these forms if you need to send us (or update) your bank details, change reactive meter, change contact details, or have a query or dispute.
Each form contains details of how to send them back to us.
Each month we will send reports to service providers to allow them to validate payments as quickly and as easily as possible.
Preliminary statements and payment estimates
Both a preliminary statement of the ancillary services and a payment estimate for these services are issued by the eighth business day of the month following when the service was provided.
Preliminary statements are not produced for short term operating reserve (STOR) service.
Final statements and self-bill invoices
A final statement for each ancillary service, along with the self-bill invoices, is issued by the eighteenth business day of the month following when the service was provided.
