Britain’s clean energy system achieves historic milestone in 2019!

Land and assets

We own the gas transmission system in Great Britain, which is made up of approximately 7,660 kilometres (4,760 miles) of high-pressure pipe and 618 above-ground installations.  We invest in the communities we serve, finding better ways to connect homes and businesses to the energy they need.  Here you can find out more about our assets, working near them, and projects we're undertaking to improve them.
