Understanding Distribution Network Operators and your EV charger installation
As part of installing your new EV charger, it's important to understand the role of Distribution Network Operators (DNOs) and how they can impact your installation process. DNOs are licensed entities responsible for managing the network infrastructure that delivers electricity from the national transmission network to residences and businesses in the UK.
DNOs own and operate the network of cables, transformers, and towers that distribute electricity across the UK. There are fourteen licensed regions for electricity distribution in the UK, each managed by six company groups.
Major DNOs in the UK include Electricity North West, Northern Powergrid, SP Energy Networks, SSEN, UK Power Networks, and Western Power Distribution. Electricity suppliers, such as Octopus Energy or EDF, are different from DNOs. Suppliers are chosen by consumers to purchase electricity, while DNOs focus on delivering electricity to households and businesses.
Some properties may be on a "looped supply" where two properties share a single electricity service cable connected to the main network. This setup allows for the distribution of electricity load among multiple households based on their diverse electricity usage patterns. Identifying if your property is on a looped supply can be done by examining your electric meter for two service cables entering it. If your property is on a looped supply, your DNO will need to unloop the supply before installing your EV charger. This upgrade is usually free of charge.
The installation of your EV charger may be delayed slightly until the upgrades are completed.
It's important to provide your MPRN/MPAN to us so we can contact your DNO and ensure that your property and the network are ready for the installation of your new EV charger. Our team has tools to help identify if you are on a looped supply, but speaking to your DNO is essential for accurate information and necessary upgrades.
