EV and HP Installers
Installers of Electric Vehicles or Heat Pumps are required to notify their Independent Distribution Network Operator (IDNO), or if the combined system load exceeds a certain level, to apply for a connection. We will normally respond within 10 days, provided all required data has been submitted.
This process helps IDNOs to ensure that the system has sufficient capacity and can continue to operate in a safe and reliable manner. It can provide assurance to third parties that all appropriate checks have been carried out and, in some instances, may be a requirement of household insurance cover.
The connection process has been developed by the Energy Networks Association (ENA), the main industry body that represents DNOs and IDNOs including GTC. The new connection notification/application process is intended to be straightforward and easy to use. It is relevant for both Electric Vehicle Charging Points (EVCPs) and Heat Pumps (HPs) at existing or new domestic premises.
The ENA website also includes guidance for installers on assessing the capacity of existing services to buildings. Most domestic services provided by GTC are 100A single phase (230V), but some 80A or 60A services may exist. Older services from other DNOs may be rated less than this.
We encourage all installers to talk to us and use the notification/application process as appropriate.
