Land and assets

We own the gas transmission system in Great Britain, which is made up of approximately 7,666 kilometres (4,740 miles) of high-pressure pipe and over 500 above-ground installations. The National Transmission System is the backbone of Britain’s energy system today and will play a leading role in the transition to a clean energy future that works for every home and business. Ultimately, we keep households warm and underpin their quality of life.  Here you can find out more about our assets, working near them, and projects we're undertaking to improve them.
