How Much Does Public EV Charging Cost?

Public EV charging in the UK costs roughly 45 to 80p per kWh at rapid DC chargers, while slower public AC charging is usually cheaper. That means a rapid top-up is far dearer than charging at home, where standard rates sit around 25 to 28p per kWh and off-peak EV tariffs can drop to roughly 7 to 10p per kWh. As a rough guide, adding around 40kWh at a rapid charger might cost somewhere between £18 and £32, though prices vary by network, location and time. For most drivers, public rapid charging is best kept for longer journeys, with home charging handling everyday needs. If you mostly charge on-street or at destination points, having the right cable for your car matters. Always check current rates on each network's app before you plug in.

At a glance: public EV charging costs

How much does rapid charging cost per session?

Rapid charging usually costs the most per unit, often around 45 to 80p per kWh. For a rough example, adding about 40kWh, enough for a decent chunk of range, might cost somewhere between £18 and £32 depending on the network. Ultra-rapid chargers can sit at the higher end. Because you pay per kWh, the cost scales with how much you add, not how fast. Prices differ widely between networks and change often, so check the app or screen for current rates before you start.

Why is public charging more expensive than home?

Public charging costs more because networks carry the price of hardware, installation, maintenance, grid connection and site rental, plus a margin. Rapid DC chargers are especially costly to install and run. Home charging avoids most of these overheads, which is why standard home rates near 25 to 28p per kWh, or off-peak EV rates around 7 to 10p per kWh, undercut public prices. The convenience and speed of public rapid charging is what you pay a premium for on longer trips.

Is slower public AC charging cheaper?

Yes, slower public AC charging is usually cheaper than rapid DC, and some destination chargers at hotels, car parks or supermarkets are low cost or even free while you shop. AC points run at around 7 to 22kW and use a Type 2 connection, so you generally bring your own cable. That makes them a good middle ground for topping up over a couple of hours. Speeds and prices vary by site, so check current rates and whether a cable is provided.

Do you need your own cable for public charging?

It depends on the charger. Rapid DC chargers are always tethered, meaning the cable is attached, so you never bring your own for those. Slower public AC chargers are usually untethered, so you plug in your own Type 2 cable. Keeping a Type 2 cable in the boot means you can use the wider network of AC points, not just rapid ones.

Which cable for public AC?

• A Type 2 cable covers almost all UK EVs sold since 2018
• A 5m cable suits most bays, 7m or 10m helps with awkward parking
• See our Type 2 charging cables range

How can you keep public charging costs down?

Charge at home whenever you can, since it is nearly always cheaper. On the road, favour slower AC or destination chargers for planned stops and save rapid DC for when you genuinely need speed. Some networks offer subscriptions or memberships that lower the per-kWh rate if you use them often, so compare those against pay-as-you-go. Avoid charging to 100% on rapids, as the last stretch slows down and costs more time. Always check current rates before starting.

Frequently asked questions

How much does public EV charging cost in the UK?

Rapid DC charging usually costs around 45 to 80p per kWh, while slower public AC charging is generally cheaper. Adding about 40kWh at a rapid charger might cost roughly £18 to £32 depending on the network. Prices vary widely and change often, so check current rates on the network's app before you plug in.

Is public charging more expensive than charging at home?

Yes, in nearly all cases. Home standard rates sit around 25 to 28p per kWh, and off-peak EV tariffs can drop to roughly 7 to 10p per kWh, both well below rapid public charging at around 45 to 80p per kWh. Home charging is the cheapest option for everyday driving.

Do I need my own cable at public chargers?

For rapid DC chargers, no, they are always tethered with the cable attached. For slower public AC chargers, you usually bring your own Type 2 cable. Keeping a Type 2 cable in the boot lets you use the wider network of untethered AC points, not just rapid chargers.

Why is rapid charging so pricey?

Rapid DC chargers are expensive to install, maintain and supply with power, and networks add a margin on top. That cost is passed on through higher per-kWh rates, often around 45 to 80p. You pay a premium for the speed and convenience, which is why rapid charging suits longer journeys rather than daily use.

Are destination chargers cheaper or free?

Sometimes. Destination AC chargers at hotels, car parks and supermarkets can be low cost or free while you use the venue, though many now charge. They run at around 7 to 22kW on a Type 2 connection, so you usually need your own cable. Check the pricing and current rates at each site before relying on it.

How can I reduce my public charging bill?

Charge at home when you can, use slower AC or destination chargers for planned stops, and save rapid DC for when speed matters. Consider a network subscription if you use one often, as it can lower the per-kWh rate. Avoid topping up to 100% on rapids, since the final stretch is slow and costly. Check current rates.

Public charging is a top-up tool, not a substitute for cheap home charging, so plan your journeys around slower AC where you can and keep rapids for long trips. To cut your everyday costs, see our guide on how to cut your EV charging costs and compare the best EV tariffs in the UK. To use untethered AC points on the road, keep a Type 2 cable in the boot or find the right cable for your car. Always check current rates before charging.
