Electric vehicle (EV) owners who depend on public infrastructure rather than home charging are facing a looming financial squeeze. As charging network operators struggle with skyrocketing overheads, industry leaders warn that the burden of these costs will inevitably be passed on to the motorist.
The Surge in Fixed Costs
The primary driver behind rising prices is not the cost of electricity itself, but the fixed costs associated with maintaining a connection to the power grid.
Osprey, a major UK rapid-charging network, recently highlighted a staggering disparity in site costs. In one notable instance in Wolverhampton, annual fixed charges for a single site surged from just £87 to £33,651 in five years.
According to Andrew Nosworthy, Osprey’s commercial director, the industry has been absorbing these massive increases for as long as possible, but the current model is becoming unsustainable.
Breaking Down the Price Tag
To understand why charging feels expensive, it is necessary to look at what makes up the price per kilowatt-hour (kWh). Currently, the average cost for rapid and ultra-rapid charging sits at approximately 76p per kWh.
Industry body ChargeUK provides a breakdown of where that money actually goes:
– Standing Charges: Roughly 30p per kWh (these have risen by nearly 500% since 2020).
– Policy Levies: Between 6p and 10p per kWh.
– VAT: Approximately 10p (based on a 20% rate).
This means a significant portion of what a driver pays at the plug has nothing to do with the actual energy consumed, but rather the cost of keeping the charger “on call” and ready for use.
The “Capacity Gap”: Paying for the Future
A central question arises: if only about 5.4% of UK vehicles are currently electric, why are these fixed costs so astronomical?
The answer lies in infrastructure scaling. To support a future where millions of EVs are on the road, operators are investing heavily—roughly £6 billion —into the network before it becomes profitable.
“The industry is paying standing charges based on future capacity, not current utilisation,” explains Jarrod Birch of ChargeUK.
Because the electrical grid must be built to handle “peak demand” (the moments when many cars are charging at once), operators must pay for massive amounts of capacity that often sit idle. Some operators report that their sites are currently operating at only 25% to 33% capacity, yet they must pay the full price to ensure the grid can handle the day the demand eventually arrives.
The VAT Uncertainty
The cost of public charging is also caught in a legal tug-of-war regarding taxation.
– The Precedent: A February tribunal ruled that public EV charging should be taxed at the 5% domestic rate rather than the 20% commercial rate, which would have significantly lowered prices for drivers.
– The Current Status: The UK government has signaled its intent to appeal this decision, leaving the potential for cheaper charging in a state of legal limbo.
Impact on the Transition
The financial reality of public charging creates a “charging divide.” While homeowners can take advantage of lower overnight electricity rates, those reliant on public networks—including many fleet drivers and urban residents—face much higher operational costs. As noted by the British Vehicle Rental and Leasing Association (BVRLA), these high costs remain a significant barrier to widespread EV adoption.
Conclusion
As charging networks prepare for a high-demand future, they are currently forced to pay for massive electrical capacity that is not yet fully utilized. Until demand catches up with infrastructure, or tax and grid policies are restructured, the cost of public charging is likely to remain a significant hurdle for EV users.
