Cost of 15,000 miles in fuel
1kWh = 3.5 miles
10,000 miles worth of charge at home using EDF's Go Electric off peak tariff rate @ 8p per kWh.
8p per kWh/ 3.5 miles = cost of 2.29p per mile. 2.29p x 10,000 miles = £229
5,000 miles of charging at work using average UK wide unit rate of 19.49p per kWh (inc 20% VAT) based on EDF's SME Fixed for Business Tariff.
19.49p per kWh/3.5 miles = cost of 5.57p per mile. 5.57p x 5,000 miles = £278.40
£278.40 + £229 = £507.40
calculated at 10.7p per mile for a 2019 BMW 3 Series Saloon 320i SE Sport-Auto
10.7p X 15,000 miles = £1605
London Congestion Charge: £10.50 per day (autopay) x 225 estimated working days = £2362.50
