EV Home Charger Installation

Safe & Easy Charging with an EV Home Charger

Charging your electric car at home will save you up to £1000 per year

Once your EV home charger is installed, you pay for the electricity you use to charge. Typical overnight electricity rate in the UK is 10p per kWh.

  • Cost of driving an electric car is about 2p per mile, which means EV drivers can save up to £1,000 a year when compared to driving a petrol or diesel car (which costs 15p per mile).
  • Electric car drivers get a £350 grant for purchasing and installing a home charger with the OLEV grant.
  • Homeowners with solar panels enjoy completely free car charging

*2p per mile based on 10p/kWh Economy 7 rate and 155 mile range of 30kWh Nissan LEAF.
**Petrol cost based on AA driving expenses report 2014/15.


Goverment Approved. The EVHS (Electric Vehicle Homecharge Scheme) funds up to 75% towards the cost of installing your electric vehicle chargepoint.

How It Works

From EV Home Charger Installation to Charging your Electric Car

In under 3 hours your charging point will be ready and you can begin charging your electric car at home.

Quick Install

Get an EV home charger installed by Forever Green Energy. It takes 2-3 hours for our qualified installers to fit your EV charger. The Zappi is OLEV approved, meaning you’ll get a £350 grant toward the install.

Easy setup & charging

Your Zappi EV Charger will fit discreetly outside or in your garage and it plugs directly in to type 1 or type 2 connectors – so it will charge all types of electric car.

Not only does it plugin to the grid, Zappi uses power generated from your solar panels. Yay! Free energy.

Time to plug in

Once installed, you’ll be able to plugin your electric or hybrid car. A full charge will take 3-4 hours. However, you can run a quick charge for 40-60 mins.

Your EV home charger keeps charging while you’re using home appliance

Your Zappi EV charger will charge your car until it’s full. It’ll do this in the most eco-friendly way by continually adjusting the power consumption in response to other items in your home that are using electricity.

Charging modes explained

The Zappi charger diverts excess solar energy generated from your solar panels directly into the battery of your car, allowing you to fill your car with the power of the sun.

The Zappi has 3 modes – Eco+ (solar charging), Eco (standard 3.6kW slow charge) and Fast (7kw fast charge), and you simply choose how to charge when you plug in.

OLEV Approved

Eco (Solar Charging)

Charge power is adjusted in response to changes in how you use electricity in the home, so that you get power where you need it and the charger dosen’t affect your day-to-day-life. Charging continues until the vehicle is fully charged.


This mode is similar to Eco, but charging will pause if there’s too much imported power from the grid. Charging continues when there’s surplus energy available e.g. from your solar battery.


The quickest way to charge your car. Using solar power and energy from the grid to charge your call at max power as fast as possible.


Did You Know?

It costs £4.50 to fully charge your electric car*, which will get you 155 miles!

*based on a Nissan Leaf

  • Electric cars costs as little as 2p per mile so you can save up to £1,000 a year in fuel savings.
  • Get up to £3,000 off the cost of your new electric car with the Plug-in Car Grant.
  • Get up to £350 off the cost of a home charging point installation with the OLEV Grant

This is a government grant for electric cars 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.
  • Available for most electric cars and plug-in hybrid cars.
  • You can claim one charging per eligible vehicle and up to two charging points per household.

To qualify for the OLEV Grant, you need to have purchased an eligible electric or plug-in hybrid vehicle from 1st April 2015 onwards.

  • You must have off-street parking.
  • You must use an OLEV-approved home charging point installer.

In short, nothing.

As the CO2 emissions produced by electric cars and plug-in hybrids are zero or under 100g/km, these cars are currently being categorised in Vehicle Excise Duty (VED) band A and therefore are zero-rates for standard car tax.

However the electric car tax is changing from April 2017, a new set of VED bands will be introduced (there are currently 13) which will mean any vehicle with an engine will need to pay tax. Battery Electric Vehicles (BEVs) will remain in VED Band A, which stays at zero-rated standard tax for both the first year and all subsequent years.

With a Zappi EV home charger (which we can install), your electricity is fed directly from your solar panels (if you have panels installed).

Meaning, you don’t have to rely on the grid to fuel your electric car with electricity.

Solar panels = free fuel for your electric car.

Time to charge an electric car can take as little as 30 minutes or up to 12 hours. The time it takes to charge depends on the size of the battery and the speed of the charging point.

  • A typical electric car (Nissan LEAF 30kWh) takes 4 hours to charge from empty with a 7kW home charging point.
  • 3.7kW home charger provides about 15 miles per hour of charge.
  • 7kW home charger provides about 30 miles per hour of charge.
  • A rapid charger at motorway service stations can charge your car to full in about 30 minutes and is ideal for long distance journeys.
  • Charging rates can differ based on the ambient temperature, the state of the battery (e.g. empty or half full) and the maximum charging rate of the vehicle.

There are 5 different connector types for charging your car. Depending on your EV car, your different connector points could be one of the following:

  • UK Three-pin
    A standard UK plug, this connector can be used to charge some EVs but typically lacks the safety and speed.
  • Type 1
    A five-pin plug that also features a clip. This connector is typically found on Asian brand manufacturers such as Nissan, Honda, Mitsubishi etc.
  • Type 2
    A seven-pin plug with one flat edge. This connector is typically found on electric cars manufactured by European brands such as BMW, Tesla, Volvo etc.
  • CHAdeMO
    A round four-pin plug. This connector is only used for rapid charging points and is typically compatible with EVs manufactured by Asian brands e.g. Mitsubishi.
  • Combined Charging System (CCS)
    Ccs – Standardised by the EU. This connector is only used for rapid charging points and is typically compatible with EVs manufactured by European brands e.g. Volkswagen.
