We have published our Electric Vehicle (EV) Strategy, setting out the principles we will apply to support the decarbonisation of transport. We are calling on our customers and stakeholders to provide feedback to ensure our priorities and requirements are at the heart of this critical transition.
We recommend speaking to an electrician/installer to see if your home wiring is sufficient to support a EV charger or if you need to apply for an upgrade or new connection. (This is also the same process you need to follow if you are looking to install a ground source heat pump.)Your installer should have competed an Adequacy of Supply Assessment. If your supply is adequate for the charging point, your installer can notify us of the installation by completing the EV/HP online application.
Once the charger or heat pump is installed, your installer should notify us within 28 days of commissioning.
If your supply is not currently adequate, your installer will need to contact us by phone to request a supply upgrade. Your installer should also contact us if there are concerns over maximum demand or the cut-out.
It is important that we have visibility of where electric vehicle charging equipment is being connected to help us locate increased demand and ensure the network is fit for purpose. We want to make it simple and easy for you to notify us when you are installing an electric vehicle charging point. Please note that it is the installer's responsibility:
• Before installing the charging equipment, to assess how adequate the electricity supply capacity is for the new electric vehicle load plus any existing load.
• Before installing the charging equipment, to assess the adequacy of the earthing
• Notify us (or another electricity distribution operator) after you have installed the charging equipment within 28 days.
• Check who your local electricity network operator is here. Our two licence areas cover the south of England and north of Scotland, but there are Independent Distribution Network Operators who operate within these areas.
If the property does not pass the adequacy test, you have concerns over maximum demand or the cut-out please contact our Connections and Engineering team to request a supply upgradeLooking for an Meter Point Administration Number (MPAN) for a property? The customer you are installing the charge point will be able to find the MPAN on their electricity bill. Find out more here.
Care should be taken when considering the
connection of Low Carbon Technologies (LCT) such as electric vehicles (EVs), as
studies such as My Electric Avenue have shown that the use of slow chargers
(3.5 kW) can more than double the peak demand of a domestic property.
Charging events will often last for several hours
at the sustained rate of the charge point, affecting the after diversity
maximum demand (ADMD) of electric vehicle (EV) charging – as a result, the
total kW rating of the EV charging point should be added to the ADMD values for
domestic properties, unless there is more than 20 EV charging points on the
feeder in which case we apply a 0.5 diversity factor which means half the total
kW rating of the EV charging point can be used.
Full guidance can be found in our Planning
Standards for Low Voltage Distribution Network (TG-NET-NPL-001) policy
We are committed to reviewing whether these figures
should be revised in light of the latest datasets as they become available, and
will update our stakeholders if/when we do
You can now apply for EV/HP applications online.
