The UK government currently offers businesses a contribution to the cost of WorkPlace charging of £500 per charger, for up to 20 chargers. Click here for more information.
The installed cost of a commercial EV chargepoint is typically £1000 to £1500 +VAT, depending on the charger model, communications required, number of chargers installed and the install specifics in terms of cabling, fixings and foundations etc.
If the charger is for work purposes (off-street, supplying private users of the business rather than members of the public), it should qualify for a £500 grant under the Workplace Charging scheme.
So let’s work to a net installed cost of £1000+VAT.
Now suppose one person charges their car for 250 days a year, using 25kWh each charge. And let’s say you are able to ‘sell’ electricity to them at a profit of 4p per kWh (either charging directly per kWh, or by taking payment for charger time). So every day you make £1 profit on the charger, with total ‘gross profit’ of £250 per year.
The annual running costs of the charger will depend on the product you buy and the charger management model you adopt, but the cost is unlikely to be more than £50 per charger per year in data fees and / or time.
So overall you can make a £200 profit each year from a single chargepoint.
In other words, even with one user per day, weekdays only, the charger can pay for itself in 5 years. If two people use it per day, the payback time will fall to under 3 years.
With a 7kW charger, 25kWh requires 31/2 hours charge, so realistically, it’s reasonable to assume that two people will use the charger every day.
A payback time of 3 – 5 years is very reasonable, particularly is by installing a charger, you are doing the right thing from a CSR point of view, whilst meeting the needs of your employees.
And the charger should last for several years.
