In this article, we examine the serious risks of installing an EV Charger Installation without notifying the Distribution Network Operator (DNO) and using an unregistered installer.
As electric vehicle (EVs) become more common across the UK, many homeowners are opting to install dedicated EV chargers at their properties. However, this process involves more than convenience — it must meet legal and safety regulations. A key part of this is notifying your local Distribution Network Operator (DNO).
1. What is a DNO
A Distribution Network Operator (DNO) is a company responsible for operating, maintaining, and managing the local electricity distribution network. Essentially, they deliver electricity from the high-voltage transmission network to homes and businesses at a usable voltage.
The DNO is responsible for the safe and reliable operation of the local electricity grid and they:
- Manage the local power lines and substations: They own and maintain the cables, poles, transformers, and substations that bring electricity from the national grid to your property.
- Ensure reliable electricity supply: They monitor and maintain the network to prevent outages and quickly fix any faults.
- Handle connections: If you want to connect something new to the electricity network — like an EV charger, solar panels, or even a new home — the DNO assesses and approves those connections.
- Upgrade infrastructure: If your property needs more capacity (e.g., due to EV charger installation or home extensions), the DNO arranges necessary upgrades to handle the increased demand.
When a charger is installed, especially one rated at 7 kW or higher, it can place additional load on the network. Without notification, the DNO cannot assess the impact or carry out necessary upgrades. This can lead to:
- Overloaded network infrastructure
- Risk of electrical faults or fire
- Delays or disconnection if the installation is non-compliant
- Breach of legal and regulatory obligations
When you choose JG Electrical Services Ltd, you ensure your EV charger is installed safely, professionally, and in full accordance with legal requirements.
2. Why You Must Notify the DNO of EV Charger Installation
Notifying your DNO is not just good practice — it is a legal requirement.

Any new EV chargepoint installation that adds demand to the local electricity network must be assessed for safety and capacity.
The DNO is responsible for the safe and reliable operation of the local electricity grid. When a charger is installed, especially one rated at 7 kW or higher, it can place additional load on the network. Without notification, the DNO cannot assess the impact or carry out necessary upgrades. This can lead to:
3. Building Control Notification
In addition to notifying the Distribution Network Operator, it is also a legal requirement to inform your local Building Control authority when installing an EV chargepoint. Building Control Notification ensures that electrical installations comply with the UK’s Building Regulations, particularly Part P which covers electrical safety in dwellings. This notification helps guarantee that your EV charger is installed safely and meets all relevant standards. Failure to notify Building Control can result in enforcement actions or complications when selling your property.
When you use JG Electrical Services Ltd, we handle this notification on your behalf as part of our full installation service, ensuring your installation is compliant and stress-free.
