At Greenmile Electrical all the EV charge points that we install are OLEV approved and conform with the latest BS 7671 wiring regulations and the IET best code of practice for EVs.
A standard installation includes:
- Your selected EV charge point.
- A 10m cable that runs from your fuse box to your vehicle’s charge point which will either be installed within surface mini trucking (inside property) or clipped neatly to your property’s external wall.
Note – We aim to keep the installation as aesthetically pleasing as we can, ensuring that cables are hidden both internally and externally, where possible.
- Enough space within your fuse box, enabling us to install a separate electric circuit for your EV charging point.
Upon completion your charge unit will be fully inspected and tested by our highly qualified electricians and you’ll receive an Electrical Installation Certificate (EIC).
Before installing any charging equipment, it’s our responsibility to ensure that your property complies with all the relevant electrical standards. If any non-compliances are identified, we will discuss them with you before any work begins.
➢ The ChargePoint must be fixed to the main property and able to utilise the property’s earthing arrangement
➢ Property’s earthing arrangement must meet current regulations – we are required to check this by law (upgrades will usually cost extra)
➢ No groundworks
➢ You must comply with the terms and conditions of the OLEV Domestic Scheme, and your property’s earthing arrangement must meet legal regulations.
What would cause the price to vary?
➢ The price for charge point installation will vary if the above criteria are not met. Any other work will be charged additionally.
➢ Cable runs – exceeding 10 metres.
➢ A mini consumer unit c/w overload and fault current protection is required, as there is not sufficient space on the existing consumer unit.
➢ Any additional mechanical protection required for the cabling, ie trunking, conduit, etc (not required under regulations);
➢ Any cable chasing requested by the homeowner
➢ Any ground works requested by the homeowner
➢ The necessity to introduce an alternative earthing system, i.e. an earth rod/inspection chamber.
➢ The necessity to install a high gain antenna in the case of poor GPRS signal.
You can charge your electric vehicle at home or at one of the public charging points.
Charging your electric vehicle at home is safe, convenient, and above all, cost-effective. Installing home charging points is what we specialise in.
You may charge your car at home or at a public charge point station. It is much more cost effective and convenient to charge your car at home.
Every electric car comes with a different-sized battery. The capacity of a battery is usually expressed in kilowatt hours (kWh), which is a measure of the energy storage available. So to calculate how much it costs to charge your car, you can look at the cost of electricity (either at your home or at a public charging point) and calculate it by the size of your car’s battery.
A Tesla Model S. has a 100kWh battery. The average cost at a public rapid charging point in the UK is approximately 35p per kWh. Therefore the cost to fully charge the battery is £35.00 (100 x 35p). If you were charging at home, the average cost is more like 13p per kWh, therefore, the cost is a very reasonable £13 (100 x 13p). Considering that full tank of petrol/diesel for an average executive car costs on average £70-100, that’s a major saving.
As little as £479* !
With Greenmile Electrical, a home charger can be purchased and installed for £479* (incl VAT) if your car qualifies for OLEV grant.

The length of time all depends on the size of the battery and the speed of the charging point.
A typical electric car (60kWh battery) takes just under 8 hours to charge from empty-to-full with a 7kW charging point.
Please see below some examples of estimated charging times:
➢ Approximately 30 minutes using a 50kw EV rapid charge point. (Mainly service stations etc.)
➢ 1 hour at 22kw (Mainly commercial & industrial)
➢ 3-4 hours using a 7kw (Domestic)
➢ 6-8 hours using a 3kw charger (Domestic)
Some hints and tips for charging your car:
➢ Regularly top up your charge, rather than waiting to recharge from empty.
➢ Most electric cars are able to add up to 100 miles of range in 35 minutes using a 50kW rapid charger.
➢ The bigger your car’s battery and the speed of the charging point will directly affect the amount of time it takes to charge.
Both variations of charge points will charge your EV at the same rate. The only difference is how you connect them to your vehicle. Many people opt for tethered, because it gives EV drivers the flexibility to leave their EV’s charging cable in the boot. So, you simply park and plug-in.
Socketed units are the best way of future-proofing your charger, because they give you the power and flexibility to change the lead to suit each vehicle you may drive. This spares you from retrofitting the lead or investing in an adaptor.
For more information on the difference’s between socketed and tethered charge points or any other questions that you have, please feel free to contact us. We’ll answer all your queries in detail and to your satisfaction.
