A Distribution Network Operator (DNO) is a regulated company responsible for managing and operating the electricity distribution network within a specific geographic area. Distribution networks play a crucial role in the electricity supply chain, transporting electricity from high-voltage transmission networks to homes, businesses and other end-users.
An Independent Distribution Network Operator (IDNO) is a type of electricity distribution company that operates independently of traditional Distribution Network Operators (DNOs). Like DNOs, IDNOs manage and maintain their own electricity distribution networks in specific areas, ensuring that power reaches homes and businesses efficiently.
IDNOs are private companies granted licenses to operate distribution networks in competition with DNOs. They must meet the same regulatory standards as DNOs, ensuring safe and reliable electricity distribution. However, their competitive edge can drive improvements in service quality, innovation, and cost-effectiveness.
Choosing Serconnect means you benefit from a highly personalised service, faster completion times, and more control over your timelines and budgets. Unlike traditional DNOs, we offer a single point of contact and in-house expertise to ensure your project is completed without delays or compromise.
An Independent Connection Provider (ICP) is a specialised company authorised and accredited to design, install, and connect electrical infrastructure to the distribution network.

ICPs emerged from a legislative change in the early 2000s when OFGEM opened up the electrical service market. This change aimed to improve competition and ensure customers received the best prices available for their electrical connections.

ICPs are usually contracted by developers, businesses, or individuals who need a new electricity connection for their premises or projects. They offer a competitive alternative to traditional DNOs, providing tailored and efficient connection solutions.
