We deal with all aspects of contracts for connections to use the National Electricity Transmission System (NETS). We provide industry-related and large connections. We do not supply or bill domestic consumers. If you have an enquiry about a domestic property or a small/medium industrial property (not a power station), please contact your local distribution network operator (DNO).
