The CVA process ensures that all claims for delivery of gas into the pipeline system are valid and add up to the total quantity metered by National Gas, who can then allocate appropriate charges to gas shippers for using the network.
The role of the agent was established by gas shippers when the Network Code was introduced in 1996, as an independent and confidential service provider who would be informed of all quantities of gas bought and sold at the entry points to the National Transmission System. Claims Validation Services Limited (CVSL) contracts the service on behalf of shippers. GMSL was appointed as the CVA in October 2004.
The CVA process is carried out by a dedicated team at our Birmingham office. Data from shippers and producers are gathered and processed using the CLAIM3 system. Initial submissions are processed on a daily basis to ensure initial invoices are as accurate as possible, and final allocations are calculated on a monthly basis. Shippers and producers can use a website to enter their data and view processing results, or they can upload and download data using the website or a dedicated API.
