About the energy industry

Energy network operators manage and maintain the wires, pipes and other infrastructure which delivers electricity and gas to your home, business and community. If you'd like to learn more, we have created a dedicated page explaining how the energy networks operate.

Together, our industry employs around 50,000 people in the UK and Ireland, including 45,000 in Great Britain. Millions of kilometres of cables and pipes deliver electricity and gas to more than 30 million homes and businesses and we're spending and investing billions of pounds upgrading, maintaining and preparing the networks so they can continue to deliver a safe, sustainable and reliable energy system in the future.
