National Transmission System Connections

The National Transmission System (NTS) transports high pressure natural gas around Great Britain via thousands of miles of pipelines, supplying large end users such as power stations, large industrial plant, whilst it also receives gas injections from the main gas terminals and gas producers. The Distribution Networks (DNs) are also connected to the NTS, however the NTS is not responsible for domestic connections. Please speak to the appropriate local DN for all domestic and small/medium non-domestic connections. Here is a link to the Energy Networks Association to help you identify which DN to contact. 

Below is the NTS Connections Flyer for more information:
