Some services offered by National Grid include gas distribution connections, land and development and balancing services. National Grid's official site has a list of all the services it offers.
For gas distribution connections, National Grid connects clients to the energy they use, whether they are keeping shops, business and factories going or heating homes. As part of its land and development services, the company works closely with the local community, planners and individuals who own land that has been crossed by its equipment.
