What Is an Independent Connections Provider (ICP)?

  • With the introduction of competition in connections, customers have the option to have the majority of connection work, which is referred to as contestable work, carried out by a third-party connection provider.
  • Other work, referred to as non-contestable work, can only be carried out by the Distribution Network Operator (DNO)
  • An ICP like Powersystems is an accredited company that can build electricity networks to agreed standards and quality required for them to be owned by either a Distribution Network Operator (DNO) or an Independent Distribution Network Operator (IDNO)
  • For an ICP to carry out some of the connection works they must be registered with National Electricity Registration Scheme (NERS) that is administered by Lloyds’ Register
  • An Independent Connection Provider (ICP) is an accredited company that carries out works on behalf of clients on the electricity network. These networks are normally owned by either a Distribution Network Operator (DNO) or an Independent Distribution Network Operator.

Independent Distribution Network Operator (IDNO)

  • An Independent Distribution Network Operator (IDNO) is a company licensed by Ofgem, to own and operate electricity networks.
  • An IDNO network will be connected to the local power network, which is owned by the DNO. However, the IDNO will be responsible for managing and operating their local network, including all future maintenance and fault repairs. Networks that are built or operated by ICPs will be adopted by either a Distribution Network Operator or by an Independent Distribution Network Operator (IDNO).
  • As a customer, you can choose to employ an accredited contractor (ICP or IDNO) to carry out contestable elements of the work, or ask us to complete all of the connection work for you.

What does an Independent Connections Provider (ICP)?

  • Contestable works do not have to be carried out by your DNO. They can also be carried out by Powersystems who are listed on the National Electricity Registration Scheme (NERS) that is administered by Lloyds’ Register.
  • Lloyds Register is responsible for assessing and accrediting the ICPs under the National Electricity Registration Scheme.
  • Powersystems carry out contestable works from low voltage up to 132 kV.
  • An ICP can carry out Contestable Works on behalf of a DNO or IDNO, or on behalf of a client.
