NEW CALCULATOR REVEALS CHARGING AN EV AT THE SUPERMARKET COSTS 200% MORE THAN AT HOME
With thousands of British motorists making the switch to electric vehicles every month, a primary question still dominates consumer forums: How much does it actually cost to charge?
To strip away the confusion of fluctuating tariffs and varying charging networks, EV specialist Volta has launched an interactive [Cost to Charge Electric Car UK Calculator]. The tool allows drivers to input their specific vehicle battery size and instantly see what a real-world, everyday top-up (20% to 80%) will cost across different locations.
To help consumers conceptualise these costs, the tool uniquely compares charging fees against familiar UK spending benchmarks, such as the average weekly grocery shop or standard hotel stay.
The Price of Convenience: Location Matters
Data processed by the tool highlights a stark reality for drivers relying solely on the public charging network. Charging a standard 60kWh family EV battery from 20% to 80% (requiring roughly 36kWh of electricity) yields vastly different bills depending entirely on where the vehicle is plugged in:
Home Charging (£0.24 per kWh): A typical charge costs just £8.64, representing just 11% of the average monthly UK electricity bill (£76).
Hotel Charging (£0.55 per kWh): The cost rises to £19.80, taking up roughly 11.5% of the average UK hotel stay benchmark (£171).
Supermarket Rapid Charging (£0.74 per kWh): Spikes sharply to £26.64—consuming over 22% of the value of an average weekly family grocery shop (£119).
Expert Commentary
Chris Munis, EV Expert at Volta, commented:
“Many new or prospective EV drivers get caught out by assuming electricity costs the same everywhere. The reality is that relying heavily on supermarket rapid chargers can cost you more than triple the price of plugging in at home.
While public networks provide essential flexibility for long-distance trips, our data shows why home charging remains the gold standard for affordability. For anyone on the fence about transitioning to electric, investing in a home charging point installation is the single most effective way to insulate yourself from public network premiums and secure the lowest possible running costs.”
Why Do Tariffs Vary So Drastically?
Volta’s research points to several factors dictating the stark price gap between locations. While home charging often benefits from overnight off-peak time-of-use tariffs, public rapid infrastructure requires massive commercial electricity supply, high initial network installation costs, and ongoing venue operating overheads—all of which are passed directly to the consumer at the plug.
