National Gas Transmission 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. We own and operate the national gas network, delivering energy to where it is needed in every part of the country.

We keep households warm and underpin their quality of life. For business, we fuel growth and innovation, and we are looking to the future by developing the hydrogen transmission system of tomorrow.

National Gas Metering maintains and manages around 7 million domestic, industrial and commercial combined gas assets across the UK. We ensure these assets remain safe, reliable and efficient for homes and businesses. We support new connections and maintain existing installations. 

As the largest asset manager of residential, industrial and commercial gas meters in Great Britain, we offer a broad range of metering services to the highest safety and quality standards, while using the most advanced engineering technologies and methods.
