Distribution Network Operators (DNO/IDNO/ICP)
Distribution Network Operators (DNO/IDNO/ICP)
Cleveland Cable Company holds the UK’s largest stock of power distribution cables, including our comprehensive range of DNO-approved medium voltage (MV) cables. Our products are used by electric utilities (DNOs) across the UK - from low voltage connections to medium and extra high voltage applications in transmission and distribution.
Specifically designed and approved for use on the UK national grid by suppliers such as UKPN, SSE, NGED, NPG, ENW, and SPEN, our DNO MV power cables ensure reliable connections from the National Grid to domestic properties.
IDNO stands for Independent Distribution Network Operator. These companies are licensed by Ofgem to own and operate electricity distribution networks, often serving new housing and commercial developments. They connect to the existing distribution network or the transmission network, providing electricity to specific areas. Unlike DNOs (Distribution Network Operators), IDNOs are not limited to a specific geographical area and can operate across the UK
An ICP is an accredited company that carries out work on behalf of clients. These companies handle the "contestable" aspects of electricity connections, such as installing cables and substations. ICPs are accredited under the National Electricity Registration Scheme (NERS). The networks they build or operate are typically adopted by either a Distribution Network Operator (DNO) or an Independent Distribution Network Operator (IDNO).
