Who is my electricity distribution company?

In order to deliver power to industrial, commercial and domestic users, electricity needs to travel from the generator via the transmission and distribution networks to the consumer (see our education pages for a more detailed explaination).

The electricity distribution networks are the penultimate stage in the delivery process. Your local distribution company is also known as distribution network operator (DNO).

  • If you have a power cut, call your DNO (phone numbers here).

  • Report cable strikes, vandalism to substations or other network structures, cables down or other dangerous incidents to your DNO immediately (phone numbers here).

  • If you are a builder or developer and require a new or additional gas or electric connection, or an alteration to an existing connection, contact the local DNO first (phone numbers here).

  • Initially, builders and contractors looking to excavate should contact the local DNO before starting work, to make sure it is safe to dig (phone numbers here).

  • Contractors seeking a temporary electricity disconnection in order to carry out work should contact their local DNO (phone numbers here).

  • Your DNO keeps records of who supplies electricity to every home in your area and can tell you who your electricity supplier is.

  • Click here to search for your DNO by postcode, together with the right phone number for your region.

Alongside the local distribution networks, there are also four high voltage transmission networks in the UK, acting like the motorway system and enabling the bulk transfer of high voltage electricity (direct from power stations) around the country.
