What is a DNO notification?
12th Mar 2020 Danny Morgan
Before we book you in for an installation, we must seek approval from your DNO. This short guide explains what a DNO is, why they are involved with your charger installation and how it could affect your installation date.
What is a DNO and what do they do?
Your Distribution Network Operator (DNO) looks after your local/regional electricity supply. The DNOs are licensed to distribute electricity in the UK and operate the cables and towers in your area.
Think of them as the go-between the National Grid and your energy company. That electricity must be transmitted and distributed to your property. It’s the distribution part that the DNO is responsible for, including the cables, poles and meters that deliver electricity to your individual property.
How can my DNO affect my installation date?
The typical lead time for an installation (from the point of payment) at Smart Home Charge is 3-4 weeks. There are several factors that can affect this, including your DNO.
All EV charge point installers must get approval from the DNO before carrying out the installation. The approval from the DNO is usually within 1-2 weeks, but can be much longer and, unfortunately, we do not have direct influence over the DNO’s speed of response.
Once we have approval from your DNO, our planning team will contact you to book an installation date.
Any delay in the installation approval from your DNO is in addition to Smart Home Charge’s typical 3-4 week lead time.
Will my DNO need to carry out works on my property?
In many cases, an EV charge point installation is a straightforward affair and just requires the DNO to check and approve the installation.
However, there are scenarios where your DNO may choose to carry out works on your property and these could include:
- Fuse upgrade
- Cable upgrades
- Unloop your power supply if you are connected to your neighbour’s supply
If the DNO determines that works need to be carried out, then this must go ahead before we can install your car charger.
This is out of our control and your DNO will arrange any works that are required with you directly.
Who is my DNO?
There are just six DNOs in Great Britain: SSE, SP Energy Networks, Electricity Northwest, Northern Powergrid, Western Power Distribution, UK Power Networks and Northern Ireland Electricity.
So who is your DNO? Well, the image from OVO Energy below gives you a rough idea, but to find out for sure you can have a look at the Energy Networks website: https://www.energynetworks.org/info/faqs/who-is-my-network-operator.html
