Frequently Asked Questions

What exactly is the OLEV EVHS grant?

As an additional incentive for UK drivers to reduce emissions, the government grant for Homecharge units has been provided by the Office for Low Emission Vehicles (OLEV).

The OLEV Grant, also known as Electric Vehicle Homecharge Scheme (EVHS), provides £350 off the cost of purchasing & installing a home charging point and can be claimed on the majority of plug-in vehicles on today’s market.

You can claim one charging per eligible vehicle and up to two charging points per household

Why do I need a home charge unit; can’t I just use a 13A plug?

Using a 13A socket is not recommended by the government or car manufacturers and it is very slow to charge.

By drawing this amount of current it is possible to strain some wiring systems which could create a fire hazard. 

And using an extension cable from your 13A plug is absolutely NOT recommended as this can overheat under the continual load.

Using a dedicated home charger unit wired directly into your consumer board (fuse box) will not overload your home’s electricity system.

When do I need to order my home charger unit?

Once you’ve chosen your new vehicle, (and checked that it’s on the approved list - Only vehicles that have been approved by the government are eligible for a grant). 

Please check link below to make sure your vehicle is listed:-
Eligible Vehicles

Customers must provide evidence of keepership, lease, be named as the primary user of an eligible electric vehicle or have a vehicle on order in order to be able to qualify for the grant.

Now it’s time to decide on your home charging unit and who will install it for you

You can refer to the Government website for approved installers in your area, many of whom will help you to choose the right charger for your needs (and pocket).

Authorised Installers

The date of installation must not be more than 4 months ahead of the date of delivery or start date of vehicle use.

How long does it take to charge at home?

Estimated time is 3-4 hours if you have a 7kW charger and 7-8 hours if you have a 3kW charger installed.

Do I need a home charger for a plug-in hybrid?

Manufacturers recommend that you keep your battery charged whenever and wherever possible to make the most of the efficiency of your car.

How much will the electricity cost me to charge at home?

Check your tariff with your energy provider.
On average it’s around 14.4p per kWh (about £3-4 for a full charge) *as of Aug 2020

How long is the cable on a tethered system?

The industry standard is 4.7m

Can I monitor the data/electricity consumption?

Yes – all systems come with smart functionality to provide data analytics

What if I move house?

No worries - we can remove and re-install your charger.

What is my MPAN number?

This is a Meter Point Administration Number (MPAN), Supply Number or S-Number.
It is a 21-digit reference used in the UK to uniquely identify electricity supply points such as individual domestic residences.
You can find on your electricity bill and you will need this as part of the OLEV grant process.

If there is a problem with the charger who do I have to contact?

All our units come with a 3 year on-site warranty.
If you do experience a problem, please call or e-mail us so that we can investigate.

Can I charge a car – other than a Tesla at a Tesla Supercharger?

NO- only Teslas can charge up at Tesla Supercharger locations. If you plan to buy any other EV than you can still use public chargers.

How can I get free public charging?

Check with your car dealer – some public charging points 'free vend' and may form part of your contract.

However, these are now less common - though some businesses (hotels and supermarkets) may continue to offer free or reduced-cost charging to their customers.

How do I minimise my charging costs?

Check with your domestic electricity supplier.

Most offer cheaper rates for overnight 'off-peak' use. Home charging points can be set to automatically charge at these lower cost times in order to minimise your running costs.

How long can I leave my EV parked for without charging?

If you anticipate that the car will not be used for several months, most manufacturers' advise that you use a trickle charger rather than leaving the main charging cable plugged in during that time. This will prevent the small 12v battery from running down.

What are the advantages and disadvantages of having a tethered charger?

Tethered leads are specific for your vehicle and for home use, makes it easier to quickly plug in your car once you return home, no need to retrieve the lead from your boot.
If you change your EV, then you will possibly also need to change your connector lead as some care need a Type 1 lead and others a Type 2 lead.

Type 1 connector (Yazaki plug) originated in Asia and N America and can charge to a max of 7.4kW and is only for single phase supply.

Type 2 connector (Mennekes) originated in Germany and widely used in Europe - can charge up to 22Kw from either single or 3-phase supplies.
Untethered (Universal) is a Type 2 charging socket offers a more future-proof solution

T3 Charging cables for France

In France, many charging points use the EV Aliiance Type 3C socket for EV Charging. The reason France adheres to this plug is because a law in France stipulates that every publicly available electric socket should have a physical cover so people cannot be electrocuted by touching the contacts.

Since there is no current allowed on the contact pins without communication between car and charging station in mode 3 charging, that risk is almost zero, but still this law results in most sockets in France being of the Type 3.

What are charging modes?

MODE 1 = 3 pin plug to car – not recommended

MODE 2 = Has protection in cable (RCD). Smart version will charge when price of electricity is lowest. Blue commando socket 

MODE 3 = Dedicated plug which is tethered to the charger or plugs in at both ends

MODE 4 = Fast charging uses 3-phase DC direct to car
