Energy Identification Code (EIC) - GB Local Issuing Office (LIO) National Grid became a Local Issuing Office (LIO) for Great Britain in June 2014, and is authorised to issue International and Local EIC Codes. On 7th September 2015, the ownership of the Gas LIO was transferred from National Grid Gas to Xoserve. This was to secure efficiencies and to avoid duplication of tasks in shipper registration, and align with processes currently undertaken by the Xoserve Customer Lifecycle team in relation to the set-up of Shippers on Gemini. National Grid will continue in their role as GB Electricity LIO. To view the full list of EIC Codes issued by the National Grid LIO please download the Public GB EIC Library spreadsheet below. Any published codes not starting with 48 are issued by other LIOs and are included for reference purposes only, as they are not actively maintained or updated by National Grid. A list of LIOs can be found here.
