Home electricity cost for 10,000 miles is the miles divided by the car's efficiency, times your unit rate. Many modern EVs use roughly 3 to 4 miles per kWh in mixed driving, so 10,000 miles is often about 2,500 to 3,400 kWh. At a cheap off-peak rate the energy can be a few hundred pounds. At a peak domestic rate it is much more. The standing charge is paid anyway if you already have a supply, so do not blame the car for the whole standing charge unless you are choosing a tariff you would not otherwise take.
Write cost to home charge 10,000 miles into the quote
Write down efficiency, annual miles, unit rate and the percentage of charging done at home. Revisit when the tariff ends.
Cost to home charge 10,000 miles
Use your own miles-per-kWh figure from the car, not a brochure best case, and the rate you will actually pay at the time you charge.
- Energy is miles divided by miles per kWh, times the rate
- Off-peak only counts if you actually use it
- Standing charge is a tariff choice
- Public miles need their own price
Check cost to home charge 10,000 miles before you accept a price
Include a share of public charging if you do long trips. Home-only sums flatter high-mileage drivers who live on motorway rapids.
The price effect of cost to home charge 10,000 miles
The install cost is separate from the running cost. A £1,000 wallbox is not part of the pence per mile unless you choose to spread it.
A miss that shows up later: cost to home charge 10,000 miles
The mistake is using a 7 pence overnight rate for every kWh when you actually charge in the early evening, or using a petrol comparison from a different size of car.
Frequently asked questions
Is 10,000 miles a fair UK average?
It is a round planning figure. Use your mileage.
Do plug-in hybrids use this sum?
Only for the electric miles. Petrol miles stay on the fuel bill. The battery is smaller, so the electricity share is lower.
Does a 22 kW charger change the cost?
Speed does not change the kWh the car needs, except for small efficiency differences. The rate per kWh is what you pay.
Are losses included?
A bit of energy is lost in the charger and the cold. If you want a margin, add a little rather than quoting a laboratory figure as a promise.
