How does the School OZEV grant work?

The Government is offering state-funded education institutions £2,500 per EV charger installed, up to a maximum of 40 chargers per site (£100k). This means Academy Trusts can now easily add EV chargers to their Schools and Nurseries with the bulk of the installation cost being covered.

The grant process couldn’t be simpler. With NSNev an OZEV installer, we take care of the full grant application and claim it for your installation. Meaning the School doesn’t have to pay up front and claim it back later.

Be quick, as this is currently only available till March 2025!!

How can I stop people using my EV charger?

Home EV charging: To stop people using your home EV charger, you can set up a pin code on your EV charger.

Business EV charging: People using the EV charger must have a RFID card to activate the EV charger.

What's the difference between an AC and a DC charger?

All home EV chargers and the majority of public charging stations use AC, while DC is used for fast charging.

In EV terms, the main difference between AC and DC charging (and the time it takes to do so) is where the conversion from AC to DC happens, i.e. in the vehicle or the charging station.

Do you require groundworks for your EV installation?

When groundworks are required for an EV charger installation we take care of everything internally.

All work will be quoted for in advance and planned out carefully to ensure a tidy and efficient EV installation.

What do 'tethered' and 'untethered' mean?

Tethered Charger: Includes a permanently attached cable.

Untethered Charger: Is when there is no cable included. The main advantage of untethered chargers is that they are much more portable. You can take them with you wherever you go, which is a big plus.


Is my home suitable for an EV Charger?

In order to have an EV Charger installed you must:

  1. Own the property
  2. Have your own off-street parking
  3. Have a WiFi connection at home.

What is the difference between a 7Kw and a 22Kw EV Charger?

The 7Kw EV Charger are designed to be put on a single phase supply which are mostly found in domestic properties and charge your car on average 30 miles her hour.

Whereas a 22Kw EV Charger can only be supplied on a 3 phase supply which are mostly found in commercial places like hotels, offices etc.

22Kw chargers give you up to 90 miles per hour. Three times the amount of a single phase charger.

Can I Charge My Car Using A Solar Panel?

In short yes you can, but there are only certain makes of EV charger that will integrate with solar panels.

We work with the Zappi EV charger that integrates with solar energy. The Zappi can both operate as a standard home car charger, using power from the grid, or it has optional charging modes which use 100% green energy generated from your own home Solar PV system.

How much does it cost to charge an electric car?

But working out how much it costs to charge from flat isn’t the greatest way of calculating cost, as how many times do you turn up to the petrol forecourt pushing your empty car in?

Electric cars are charged by always topping up. As an electric vehicle driver, if you have a charger available, just plug in and top it up.

As a business, when calculating your costs for charging staff, fleet, or customer’s EV’s, you have to take into account that most will be just topping up the charge they already have in the battery. Most people will charge at home and use other chargers to top up through the day. The chargers cut out as soon as the car is full, so never costing more electricity than is required.
