National Gas consists of three businesses - National Gas Transmission, National Gas Metering and National Gas Services.

National Gas Transmission is the backbone of Britain’s energy system today and we are working to 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.

Gas is currently a critical part of Britain's energy needs. 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 6.8 million domestic, industrial and commercial combined gas assets across the UK, enabling homes and industry to access the energy they need safely and reliably. 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.

National Gas Services is Britain's trusted authority in pipeline repair, maintenance and intervention. With our extensive expertise in both emergency and planned solutions, we ensure rapid 24-hour responses, 365 days a year - along with a full range of maintenance, inspection and repair services. We have six strategically positioned depots across England, Scotland and Wales, enabling us to serve customers nationwide.

Gas Winter Review & Consultation 2024

Our Gas Winter Review & Consultation 2024 has now been published. Whilst this winter was the fifth warmest on record, cold snaps in December meant that overall demand was similar to the last winter. Peak daily electricity generated by gas increased to 61%, the highest to date, despite gas for power generation decreasing. Exports to continental Europe through Bacton Gas Terminal have decreased and returned to levels seen in prior years.
