About ESP

ESP Utilities Group is one of the UK’s largest and longest established Independent Gas Transporters (IGT) and Independent Distribution Network Operators (IDNO), which means we own and operate gas and electricity networks, as well as gas smart meters.

We have over 650,000 customers, connected on a variety of residential, industrial and commercial networks across the UK.

As a network owner and operator, we are responsible for maintaining the network, and repairing any faults that cause interruptions to supply as quickly and safely as possible.

ESP does not build new networks, instead we adopt them from accredited Utility Infrastructure Providers (UIPs) and Independent Connection Providers (ICPs), partnering to ensure the adoption of safe, quality networks.

With 20 years’ experience in the industry, ESP’s leadership team have instilled a customer – centric culture in the business. We take great pride in ensuring we deliver and develop the best possible service for those that live and work on our networks.

The utility construction partners that we work with in adopting newly constructed networks rely on us to provide support, technical guidance and investment to deliver for their client.
