A DNO (distribution network operator) plays a significant role in the installation of an EV charger, but many people are unaware of what a DNO is and what they do.
In fact, an essential part of the process of an EV chargepoint installation is notifying your DNO.
In this blog, we will explain what a DNO is, its role in an EV charger installation and how to notify the DNO of an EV charger installation.
DNO stands for Distribution Network Operator.
Distribution Network Operators are in charge of distributing electricity from the national grid to residential and commercial properties. Their responsibilities include managing and maintaining the infrastructure network, such as towers, transformers, poles, cables, and meters that deliver electricity to customers. Distribution Network Operators are also responsible for restoring power to your homes and businesses after a power cut.
DNOs bridge the gap between the national grid and energy suppliers, such as EON and EDF.
If you are still confused, check out our blog, where we explain everything about the DNO.
In the United Kingdom, the distribution network is divided into geographic regions, each with its own DNO. There are currently 6 DNO’s in the UK.
You can use the ENA’s ‘Who’s my network Operator?’ tool to find your DNO.
In some cases, specific housing estates and streets can have a local DNO that owns the network in that particular area.
Unfortunately, you cannot change your DNO.
You must notify your Distribution Network Operator (DNO) of an EV charge point installation. The notification is needed because the DNO is responsible for ensuring that the local electricity network can safely and reliably accommodate the increased demand from electric vehicle chargers.
Installing an electric vehicle charger will draw more electricity from the grid than your home typically uses. Depending on the size of the charger and your home’s electrical capacity, this could impact the local network’s capacity to supply electricity to your property and those around it.
Notifying your DNO allows them to assess the impact of the charger on the local network and take any necessary steps to upgrade the infrastructure if needed.
The DNO notification process can be confusing if you are not an authorised EV charger installer. As such, you should contact a chargepoint installer, such as We Power Your Car, to notify your DNO and guide you through the process.
To notify the DNO of an EV charger installation, you must complete an ENA application form and email it to your local DNO.
This form can be challenging to complete if you are not an authorised EV charger installer. For example, the form requires you to calculate the maximum demand of the property, which is a complex task if you are not an electrician.
Therefore, you should get your chosen EV charge point installer to complete the form and send it to the DNO on your behalf.
In most cases, you need to submit the ENA application before the installation and wait for approval before proceeding.
However, sometimes your EV charger installer may be able to install the EV charger first and then submit the ENA form to the DNO within 28 days of that installation. But this is only when the installer deems the maximum demand to be less than 60 amps, and it meets other relevant requirements, which is rare.
We believe there is a need to contact the DNO before every installation to ensure we always have approval and can install the charger with the utmost confidence.
In most cases, we just need to wait for the DNO to check and approve our notification before we can install an EV charger. Simply waiting for approval from the DNO should not result in a substantial delay.
However, there are specific situations where the DNO process can significantly delay your electric vehicle charger’s installation date, such as when additional works are needed before they can grant approval.
Fuse upgrade: Your installer will let your regional DNO know the maximum electricity demand at your property on the ENA form. Once your DNO has been notified, they will check that your electricity supply is adequate for installation.
If they deem your supply inadequate, they may say you need to upgrade your main electrical fuse. If this is the case, your fuse may need to be upgraded before installing your EV charger, which can take time and delay your installation date.
Looped supply: In some instances, your DNO may inform you that you have a looped supply. A looped supply is where two properties share a single electricity service cable from the main network and are typically found in semi-detached or terraced houses.
An EV charger is not permitted on a looped supply by most DNOs, so the DNO may need to unloop the supply before the installation can go ahead. The unlooping of a supply can add significant delays to your charger installation.
Backlog of work: The DNO may have a backlog due to a high volume of installation requests or other factors. If your DNO is experiencing delays, your installation date may be pushed back until the DNO give the green light.
The response and duration of any additional works differs based on the particular DNO in charge, as each has a unique approach. Unfortunately, your EV charger installer has no influence over the delays caused by your DNO.
As such, it’s a good idea to plan ahead and allow plenty of time for the installation process, as it can take several weeks or even months from start to finish.
Yes, you may be charged by your Distribution Network Operator (DNO) for connecting your electric vehicle (EV) charger to the electrical grid. The charges can vary depending on the DNO and the specific circumstances of your installation.
For example, if your EV charger installation requires an upgrade to the local electrical infrastructure, such as a fuse upgrade, the DNO may charge to cover the cost of the upgrade. You can also be charged for the unlooping of a supply.
The cost of each charge point project will always vary based on the specific DNO, location and application requirements.
At We Power Your Car, we take you through the DNO application process from start to finish.
We fill out the ENA form on your behalf and liaise with the DNO directly, meaning you can sit back and relax.
We will keep you in the loop regarding the application process and any additional works that may need to be completed. Once the DNO approve your application or complete any necessary works, we aim to install your EV charger within 8-10 working days.
