Individual Network Codes

The Gas Transporters' Licences held by the owners of the National Transmission System and the main gas distribution networks require the production of a Network Code. There are six such individual Network Codes in existence at present, which can be viewed on these pages.

Summary of Individual Network Codes

The GB gas industry has evolved a single Uniform Network Code, which was written as part of the process undertaken by
National Grid to support the sale of some distribution networks. Apart from references to the particular Licence holder, each of
the six individual Network Codes is identical and contains no substantive provisions which impact the commercial and physical
arrangements which support the transportation of gas. Instead each individual Network Code references the provisions of the
Uniform Network Code, such that common arrangements apply across GB.

The Uniform Network Code, and a summary of its provisions, is also available from this website
