Third Party organisations wishing to lay gas infrastructure and transfer ownership to Northern Gas Networks, or lay infrastructure on behalf of Independent Gas Transporters (IGT) to connect to our network, must register with us as a Utility Infrastructure Provider (UIP).

• UIP registration form

Submit a quotation request when:

• the requirement of the site falls outside of the standard pressure matrix

Some connections will need reinforcement. In these cases you will be informed and will be contacted by our Reinforcement Team.
