Electric vehicle connections

Looking to install multiple EV connections?

Charging at home 

Getting your home ready to charge an electric vehicle is simple, but it’s important to make sure your home’s supply can safely handle the extra demand.

We recommend speaking to a qualified electrician or installer. They’ll check the expected maximum demand of your property (including the EV charger) and work out the correct process for connection. 

There are 2 possible routes: 

Connect and Notify

If the total demand of the property is 60 amps or less and has no safety concerns, the installer does not need to apply in advance of the installation. However, they must notify us once the charger is installed by completing the G98 – Form B. 
 
This makes sure we have an accurate record of the additional load on the network. 
 
If the property is looped (i.e. it shares a service cable with another property), an application must be submitted before installation to ensure the safety of the cut-out and to allow for unlooping where necessary. 

Load Check

If the total demand of the property is more than 60 amps or does not qualify against any other criteria for Connect and Notify, the installer must apply to connect and wait for permission before installing the EV charger.

Applications can be submitted in any of the following ways:

• Via our website
• By emailing a completed ENA form to EVHP@ssen.co.uk
• Through the Connect Direct portal

We’ll then review the information we hold on record and along with any photos you provide, including:

• The looped status of the property
• The style of the cut-out/fuse
• The age and condition of the existing connection

Providing clear photos with the application helps speed the review process. 
 
If the property’s demand exceeds what the existing supply can safely provide, due to the cut-out type, fuse rating or a looped supply, we’ll arrange for any necessary upgrade or unlooping works to be completed before installation.  
 
Once your charger is installed, your installer should submit the notification within 28 days. 

On-street Charging

If you are a Charge Point Operator (CPO) or Local Authority planning to install on-street Electric Vehicle Charging Points (EVCPs), the appropriate route will depend on whether you are installing onto existing unmetered supplies, or you require the provision of new supplies.

To utilise existing unmetered supplies, you must firstly ensure you have authority from the asset owner, verify the charging equipment complies with Elexon requirements, establish a good understanding of our technical design standards, and hold a valid Unmetered Connection Agreement before proceeding. Click here to view our requirements and guidance for using existing unmetered supplies for on-street EV charging.

If the provision of a new supply is required, either metered or unmetered, you will need to apply for a new connection with SSEN. We will assess network capacity and issue a connection offer. Click here to start your application.

Note to Charge Point Operators

Any on-street EVCPs rated above 5.75kW will require a metered connection. For those on-street EVCPs rated at or below 5.75kW, an unmetered connection may be suitable depending on your needs.

Before proceeding with any installation of on-street EVCPs, whether using an existing or new supply, we recommend reviewing our design standard: PR-NET-CAB-006 – Electric Vehicle Charging Points, Supply Arrangements – Design Standard in the G81 library (registration required) to ensure your installation meets all requirements.

Information for Installers

We rely on installers to help us keep the network running smoothly and safely. When installing EV charging equipment, please remember to:

If our assessment shows that the supply requires an upgrade, this must be completed before the EV charger is installed.
