  • Application to Offer

    When an applicant wishes to connect to the NTS or modify an existing NTS connection, they need to complete and submit the relevant Application form, which is published on this website.

    Transmission connections are only appropriate for the largest users of gas; gas distribution networks and major industrial premises such as power stations, combined heat and power (CHP) schemes and a few major energy intensive industries.
