Public vs Home EV Charging: Cost and Convenience

For most UK drivers, charging at home is cheaper and far more convenient than public charging, while public charging exists mainly to top you up on longer trips. Home charging on an EV off-peak tariff can cost roughly 7 to 10p per kWh overnight, against public rapid chargers that often sit around 45 to 80p per kWh. The trade-off is speed and access: a home wallbox with your own Type 2 charging cable tops up slowly overnight, whereas public rapid points add serious range in minutes. Get both parts right and you rarely think about charging at all.

At a glance: home vs public charging

Is home charging really cheaper?

Yes, home charging is almost always the cheapest option, especially on a dedicated EV tariff. Standard home electricity is roughly 25 to 28p per kWh, but off-peak EV tariffs such as Octopus Intelligent Go or OVO Charge Anytime can drop to around 7 to 10p per kWh overnight. On a cheap rate, filling a 60kWh battery from about 10 to 100% can cost roughly £4 to £5, against £15 to £17 on a standard rate. Public rapid charging is dearer still, so the more you charge at home, the more you save. Always check current rates before you commit.

Why is home charging more convenient?

Home charging is convenient because the car charges while you sleep, with no queues, apps or payment steps. You plug in when you park, and wake up to a full battery. Most home wallboxes are untethered, so you use your own cable and can choose a length that suits your driveway, usually 5m for most homes. There is no waiting for a free bay, no worrying whether a charger is working, and no standing in the cold. For drivers with off-street parking, this is the single biggest reason EV ownership feels effortless.

When do you actually need public charging?

You need public charging mainly for longer trips that exceed your car's range, or when you cannot charge at home. Rapid DC chargers of 50 to 350kW add a lot of range in a short stop, which is ideal on motorways during a road trip. Destination chargers at hotels, supermarkets and car parks let you top up while you are parked anyway. If you have no driveway, a mix of public and workplace charging becomes your main supply, so knowing your local network matters more.

What if you cannot charge at home?

If you have no off-street parking, you can still run an EV using public and workplace charging, though it takes more planning. On-street chargers, supermarket points and destination chargers all help. A portable charger is a useful backup where a normal socket is safely reachable, but it is slow at around 2.3kW, adding roughly 8 to 10 miles per hour, so it suits occasional use rather than daily reliance.

Practical options for no-driveway drivers

• Lamp-post or on-street chargers near your home
• Workplace charging while you are at the office
• Supermarket and car park chargers during errands
• A portable charger as an occasional backup

How do you get the best of both?

The best approach is to do the bulk of your charging at home on a cheap overnight tariff, then use public rapid charging only when you travel beyond your range. Set your car or wallbox to charge during off-peak hours automatically. Keep a good quality Type 2 cable in the boot for AC destination chargers, since many of those are untethered. This way you pay the lowest rate day to day and only pay public prices for the occasional long journey.

Frequently asked questions

Is it cheaper to charge an EV at home or in public?

Charging at home is usually cheaper, especially on an off-peak EV tariff at around 7 to 10p per kWh. Public rapid charging often costs around 45 to 80p per kWh. Standard home electricity of roughly 25 to 28p sits between the two. Rates change often, so check your tariff and the charger's pricing before you plug in.

Do I need my own cable for public charging?

It depends on the charger. Rapid DC chargers are always tethered, so the cable is attached and you never bring your own. Slower AC public and destination chargers are often untethered, meaning you plug in your own Type 2 lead. Keeping a cable in the boot means you can use both types without being caught out.

How much faster is public charging?

Public rapid DC chargers are far faster than home charging, adding a large amount of range in a short stop rather than over several hours. A typical home wallbox delivers 7.4kW, adding roughly 25 to 30 miles per hour. Rapid chargers run from 50kW up to 350kW, so they are measured in minutes for a useful top-up.

Can I run an EV with no home charging?

Yes, many drivers run EVs without home charging by using on-street, workplace, supermarket and destination chargers. It takes more planning and usually costs more than a home off-peak tariff. A portable charger can help where a safe socket is reachable, but at around 2.3kW it is slow and best kept for occasional backup use.

Is home charging safe to leave overnight?

Yes, a properly installed home wallbox is designed for unattended overnight charging, which is how most EV drivers charge. The Type 2 connector locks while charging and is weather-resistant when plugged in. Portable chargers should be plugged directly into a suitable wall socket on their own circuit, never through an extension lead or multi-way adapter.

Should I get an off-peak EV tariff?

If you charge at home regularly, an off-peak EV tariff is usually well worth it, since overnight rates of around 7 to 10p per kWh are far lower than standard rates. Your car or wallbox can be set to charge automatically during the cheap window. Compare current tariffs, as availability and prices change, and check any eligibility requirements first.

The simplest setup for most people is home charging for daily use plus public charging for the occasional long trip.
