Information for Customers
You have a choice on who delivers your new or modified connection scheme to our distribution network. We can provide you with a complete connection service but you may also ask an Independent Connection Provider (ICP) or an Independent Network Operator (IDNO) to undertake some of the works.
Further information regarding how the competition in connections process works can be found in our leaflet here.
What is an Independent Connection Provider (ICP)?
An Independent Connection Provider (ICP) is a company that can build electricity networks for adoption by WPD. The ICP must be registered with Lloyds Register EMEA under the National Electricity Registration Scheme (NERS).
Where can I find an ICP?
What work can be done by an ICP?
Connections works are split into contestable and non-contestable works. Contestable works can be carried out by WPD, an ICP or an IDNO. Non-contestable works can only be undertaken by WPD or our agents. A table of contestable and non-contestable activities can be found at the bottom of this page.
Click here for details of the operational activities that an ICP is permitted to undertake on the WPD network.
What is an Independent Network Operator (IDNO)?
An Independent Network Operator (IDNO) is a company that can construct electricity networks, arranges connections to WPD’s network, retains ownership of and be responsible for the operation of that new network.
Where a new connection and new network is built by an ICP it may be adopted by an IDNO. In this case, the end customers connected to this new network will be customers of the IDNO rather than WPD.
Where can I find an IDNO?
A list of IDNO's can be found here.
What are Contestable and Non-Contestable Works?
Contestable works are the elements of the connections work which can be undertaken by an ICP or IDNO rather than WPD. Non-contestable works are the elements of the connections work which must be completed by WPD or our appointed agents.
A list of activities can be found in our connection charging methodologies. Click here to view the methodology documents for each region.
