Tethered and untethered electric vehicle chargers each have their pros and cons.

Pros of tethered chargers

  • Tethered electric chargers allow you to simply park up and plug in.
  • You can keep your other charging cable in the boot of your car.
  • More secure than an untethered unit.
  • You don’t need to buy an additional cable.

Cons of tethered chargers

  • Cables often come in fixed lengths, so you can’t buy a replacement if needed.
  • They lock you into the Type 1/Type 2 choice. If you change car, or even if a new cable standard emerges, you’ll need to buy a new charger or an adapter.
  • They aren’t as ‘neat’. The cables are permanently on display and you’ll have to coil/uncoil every time you use it.

Pros of untethered chargers

  • You can buy multiple cables of different lengths.
  • Much more flexible and future-proofed, you are not as locked into the Type 1/Type 2 choice, either type can use the socket.
  • As EVs become more popular, visiting friends and family can also use the charger.
  • Looks a lot more discreet and tidy on your driveway or car park.

Cons of untethered chargers

  • You have to get the cable out of your boot/garage every time you want to charge.
  • Less secure than a tethered unit.
  • You may have to supply your own charging cable.

It’s possible to charge your electric car with the 3-pin plug charger cable supplied with the vehicle, but it’s slow and offers fewer options than a dedicated charge point. Some of the most common reasons our customers choose to have a fit-for-purpose charge point installed included:


Charging an electric car requires a high and consistent electric current over a long period of time. It is generally considered that a standard electrical socket is not suitable for such a prolonged period of use and overheating of the socket may occur.

Speed of charge

A 2.3kW 3-pin plug typically takes more than 20 hours to fully charge an EV, while a typical 7.4kW charging device will comfortably charge the average electric vehicle within eight hours.


One of the criticisms levelled at electric cars is the amount of time they can take to charge. However, most EV owners charge overnight with a dedicated wall-mounted device, which means they wake up to a fully charged vehicle every morning. With workplace charging stations employees can charge their vehicle during their workday, ensuring sufficient charge for the drive home.

Plug-in EVs are the future

There is no doubt that plug-in electric vehicles are the future of motoring in the UK. By starting the process of installing an EV charge point today, you will be able to enjoy faster, safer charging now and for your inevitable future electric car.

The £350 OZEV Grant

The Government OZEV Grant is designed to encourage the transition to electric vehicles. If eligible, you can qualify for a £350 Grant towards your EV home-charging device or workplace charge point. By applying today, you will be ensuring a saving of up to £350 off your electric car charge point installation.

Fast charging refers to any vehicles or chargers that are capable of charging from 7kW to 22kW. They can charge the typical Battery Electric Vehicle (BEV) in around eight hours, depending on the size of the battery. While the 22kW fast chargers are quicker, they are require a 3-phase connection which most industrial and commercial premises have as standard. Our fast chargers include those which provide power from 7kW to 22kW, which can fully charge an EV in as little as four hours but this does depends on the battery size of the vehicle.

Rapid charging refers to vehicles or chargers that are capable of charging from 43kW to 150kW. They are not available in domestic properties and are usually located at service stations, cities, and supermarkets, although rapid chargers at fuel stations are expected to become commonplace.

There are two types – AC or DC [Alternating or Direct Current]. Current Rapid AC chargers are rated at 43 kW, while most Rapid DC units are at least 50kW. Both will charge the majority of EVs to 80% in around 30-60 minutes (depending on battery capacity). 120kW and 150kW rapid charging units are becoming more common too.

Generally installations include:

  • The fitting of the selected charge point on a brick or plaster wall or pedestal if you choose that option.
  • Routing of the cable through a wall where needed.
  • Installation ofcabling, run and neatly clipped to the wall between the distribution board and the EV charge point.
  • All electrical connections at the origin of the supply and EV charge point.
  • Installation of a Type C MCB.
  • Installation of plastic conduit or trunking to conceal the interior wiring.
  • Electrical testing and the NICEIC certification.
  • Demonstration of the EV charge point functions and mobile phone App (if applicable).

Depending on additional requirements, installations may also include:

  • An earth rod in soft ground (some types of installation require an earth electrode to be fitted to comply with wiring regulations BS7671).
  • Type A RCBO and Enclosure.
  • Lifting and/or replacement of carpets and floor boards.
  • Additional metal clad consumer board.
  • Installing cabling in roof and ceiling voids.
  • Trenching or civil works for the installation of cabling.
