Zap-Map Price Index – Charging on the public network

The price to charge an electric vehicle (EV) on the public charging network can vary substantively, and prices are increasing due to current issues in the energy market.

Through the data collected to drive the Zap-Map app, Zap-Map tracks over 500,000 charge sessions each month and the latest charge point operator prices to provide an independent picture of the price paid by EV drivers across the public charging network. Updated on a quarterly basis, the Zap-Map Price Index shows the difference in prices paid depending on the type of charger and will also track how this is changing overtime.

In addition to the Quarterly Price Index, Zap-Map tracks EV charging statistics, EV sales data and offers a variety of insight reports, including the annual EV Charging Survey, designed to assist organisations of all types in making the switch to electric vehicles.

What is the average price of charging an electric car on the public charging network?

The weighted average price* to charge an electric car on the public charging network in September 2022 is 42p/kWh on fast/slow chargers and 64p/kWh for the rapid/ultra-rapid chargers.

Using an average efficiency EV* this equates to 11 pence per mile and 17 pence per mile respectively.

Across the UK, charge point operators offer a headline “pay as you go” (PAYG) price, which is the price that EV drivers can pay without a membership or a special deal.

The latest PAYG price for the top 10 rapid/ultra-rapid charge point operators can be seen on our rapid/ultra-rapid pricing page.

Prices for other charge point operators can be seen in our public charging network guides.


How are prices to charge an electric car changing over time?

Surging energy prices have resulted in increases across both fast/slow (typically on-street chargers or destination chargers) and rapid/ultra-rapid EV charge points (typically used for en-route charging). Zap-Map analysis shows that it now costs an average of 31% more to charge at a rapid/ultra-rapid device, compared to June 2022.

Similarly, the price per kWh at fast/slow devices has increased by 24% in the same period.  

The chart below shows the weighted average price of public chargers by power rating.

How do electric car charging costs compare to refuelling a petrol or diesel car?

Despite the increase in public EV charging prices, EV drivers are still in a better position than ICE drivers who have to fill up at the pumps. Typically, an EV driver will only charge on the most expensive rapid or ultra-rapid chargers for a fraction of the time.

Many EV drivers charge at home for most of their energy needs, with the energy price cap currently sitting at around 34p/kWh, and might also have the option to install solar panels, or take advantage of a lower price off-peak tariff and so reduce the cost of charging their EV further.

The infographic below looks at how charging costs may differ with three different EV driver profiles.

The first, John and Rosa who primarily charge their EV at home; the second, Michael and Marie who do about half of their charging at home, but do top-ups when the go to the supermarket and charge up at motorway service stations when on longer journey; and the third, Kris who is entirely reliant on public charging. He is able to use a slow lamppost charger to charge on most days, but when he’s on longer road trips visiting relatives he uses rapid chargers at a charging hub.

All the drivers in the above profiles enjoy savings from driving their EV compared to ICE vehicles. John and Rosa save approximately £855, Michael and Marie £680 and Kris £465 per year compared to refuelling an ICE vehicle.

Overall, although the price of charging at the most expensive ultra-rapid chargers is closest to parity with refuelling an ICE vehicle, most EV drivers use a mix of charging as above, and an EV remains a good choice for low running costs during these uncertain times and, of course, far better in terms of impact on climate change and air quality.

Using the Journey Cost Calculator, Home Charging Calculator or Public Charging Cost Calculator, you can compare the cost of refuelling a petrol or diesel vehicle with the cost of charging an EV at home or in public, allowing you to see how much you could save between different vehicles on specific journeys.

*Calculated from Zap-Map usage data covering around 70% of public chargers in the UK and over 500,000 charging sessions per month. The prices above are a weighted average price per kWh based on the PAYG price per network and the estimated total kWh delivered by each network over the month.

Membership options with discounts are available on some networks, which would reduce the price paid for regular use. In addition, some charge devices are still free, see exclusions below, which would also reduce the average price paid. 

Exclusions – Taxi-only devices; Networks which are predominantly free to use, notably ChargePlace Scotland, CYC and eCar NI.
