Yes, your distribution network operator (DNO) does need to know about a home charger — but for a standard install you almost never contact them yourself. Your installer normally submits the notification as part of the job, usually on or just after the day the charger is fitted. The cases that need the DNO involved before any work starts are the unusual ones: very large loads, three-phase work, and supplies that may not cope, such as looped connections.
Key Takeaways
- Your DNO must be told about a home charger, but your installer normally does the telling.
- Standard installs are usually notified on or just after fitting day.
- Looped supplies, three-phase work and second chargers need the DNO involved before fitting.
- Keep the installation certificate and notification paperwork with your house documents.
Who Your DNO Is, and Why It Wants to Know
The DNO is the company that owns the cables and substations bringing power to your street. It is not your energy supplier — the supplier bills you, but the network underneath belongs to the DNO, and which DNO you have depends only on where you live. A single 7 kW charger is a modest load. A street where twenty homes add one is a planning problem: the DNO uses installation notifications to see demand building up, reinforce the network in time, and spot the individual supplies — old, small or shared — that need work before a charger is added. Notification is also why home charge points are smart by law, as our explainer on how smart chargers work covers.
How Notification Normally Works
| Situation | Who contacts the DNO | When |
|---|---|---|
| Standard single-phase home charger | Your installer | Usually on, or just after, installation day |
| Looped or doubtful supply found at survey | Your installer | Before fitting — network work may have to come first |
| Three-phase upgrade or a high-power install | Your installer applies in advance | Before work — approval, and possibly network changes, needed |
| A second charger, or another large new load | Your installer advises | Before fitting, so total demand is assessed |
The notification itself is basic: the address, the charger’s rating, and details of the supply it connects to. You should receive your copy of the install paperwork — the electrical installation certificate and any notification confirmation — from the installer, and it is worth filing with your house documents. How long the whole job takes, survey to sign-off, is covered in our guide to how long an installation takes.
What You Actually Have to Do
- Choose an installer who handles the DNO notification as part of the job — ask before you book, not after.
- Make sure the survey can reach the cut-out and meter position; supply questions are answered there, not from photos of the driveway.
- Keep the certificate and notification paperwork. Buyers, insurers and future installers all ask for it.
- If you bought a home with a charger already fitted and no paperwork at all, have an installer check the installation when you next have electrical work done.
The hardware is rarely the issue. A smart wallbox such as the EVDANCE EV-ACT3204PE (three-phase, Type 2, RFID and app control) is the kind of unit installers notify every week, and three-phase homes weighing a unit like the ACS1605PE portable (11 kW, three-phase, Type 2) are exactly the cases where the advance conversation matters — because, as our single-phase vs three-phase explainer sets out, the supply is the real question, not the charger.
Frequently Asked Questions
Will the DNO refuse my charger?
An outright refusal is not the usual outcome. The common results are the notification being accepted, or network work — unlooping a shared supply, or a fuse upgrade — being scheduled first. Your installer will know which applies before anything is fitted.
Does DNO notification cost me anything?
The notification itself is part of the installer’s job. If your supply needs network work, the DNO quotes for that separately — get the figure from the DNO rather than from estimates quoted online.
I already have a charger and never heard about any notification. Is that a problem?
Probably not one that is yours to fix: notification sits with the installer who fitted it. If you have no paperwork at all, ask an installer to check the installation when you next have electrical work done at the property.
