Process for Connecting New LCT’s & Associated Forms

The process is maintained and governed by ENA’s Low Carbon Technologies Working Group. This group contains representatives of all UK transmission and distribution electricity networks, and meets regularly with industry, BEIS and Ofgem to discuss issues and agree strategies and processes for Low Carbon Technologies that connect to the electricity networks. For further information on the role of the ENA and additional information on LCT’s, please visit their Electric Vehicle and Heat pumps page here.

We have created a combined flowchart illustrating the revised connection process for both Electric Vehicles and Heat Pumps, and it can be found here. To assist with the technical details associated with Heat pumps, that are necessary for the connection process, a database of Heat Pumps has been created and can be found on the ENA website here.  

An installer can use this database to cross-reference their device(s) to determine whether they can ‘Connect & Notify’ to the DNO or ‘Apply to Connect’. The ENA will be updating this in the future to a more digital platform where manufacturers and installers can input their own HP information, to be verified by ENA Members.

It should be noted that:

•   â€‹The position remains that NIE Networks will never refuse a connection, however works may be required to ensure the connection is fit for purpose

•   Properties with an estimated maximum demand greater than 60A following the connection of an EV charger or Heat Pump - the installer must apply for a connection prior to installation by filling in the form mentioned below and NIE Networks will assess the supply capacity within 10 working days.

To assist the installer with notifying NIE Networks of new LCT equipment, we have created a combined application form for Heat Pumps and Electric Vehicles. This has been aligned with the aforementioned process, and should allow consistency of application to NIE Networks across Low Carbon Technologies. This form can be found on our webpage here. Alternatively, a Multiple Installations Form can be found here.

You must email the completed form to lctconnections@nienetworks.co.uk

If remedial work is required by NIE Networks, the time taken to carry out this work will vary depending on the nature of the upgrade required to deliver an adequate supply to the premises being assessed. Each connection is different, so the premises and network must be assessed before providing an estimated time of delivery.
