The electric vehicle (EV) revolution is in full swing, and with London’s growing commitment to sustainable living, the city is seeing an increasing number of EV owners. One of the most frequently asked questions among new EV drivers is, “What’s more affordable: charging at home or using public stations?”
In this blog, we will break down the costs and benefits of both home charging and public stations, helping you make an informed decision on how to keep your EV powered up in London.
Home Charging: Convenience and Cost Efficiency
For many EV owners, charging at home is the most convenient and cost-effective option. Here’s why:
1. Lower Energy Costs
Charging your EV at home in London typically costs less than using public stations. Most home charging stations are connected to your home’s electricity supply, which means you can benefit from lower, consistent energy rates. Many London residents take advantage of off-peak tariffs, where electricity is cheaper at night. This can significantly reduce the cost of charging, especially for those who charge their vehicles overnight.
– Average cost per kWh (home): 17-25p during peak hours; as low as 7-10p during off-peak hours.
– Average cost for a full charge: £6-£8 (off-peak).
2. Upfront Costs and Installation
Installing a home charger typically costs between £800 and £1,300, depending on the type of charger and your home’s electrical setup. However, in London, the government’s OZEV (Office for Zero Emission Vehicles) grant can reduce this cost by up to £350. Once installed, your home charger can be a long-term investment that pays for itself through lower charging costs over time.
3. Control and Convenience
Home charging offers unparalleled convenience. You don’t have to worry about the availability of public chargers, and you can charge your vehicle while you sleep. With smart chargers, you can even schedule your EV to charge during off-peak hours to take advantage of lower rates.
Public Charging Stations: Fast and Flexible
While home charging offers lower costs, public charging stations provide flexibility and faster charging speeds. Here are the key factors to consider:
1. Charging Speed
Public charging stations in London range from slower 7kW chargers to ultra-fast 300kW+ chargers. Fast chargers can top up your battery in as little as 30 minutes, which is ideal if you’re in a rush or don’t have access to home charging. Ultra-rapid chargers, commonly found at motorway service stations or in certain high-traffic areas, offer convenience but at a higher price point.
– Average cost per 22kWh (public chargers): 62-£75, depending on the speed and location.
– Average cost for a full charge (rapid charger): £10-£25.
2. Network Availability
London has an extensive network of public charging stations, with over 11,000 public charging points across the city. You will find chargers at supermarkets, car parks, and service stations, giving you plenty of options when you are out and about. However, the downside is that public charging stations can sometimes be busy or out of service, leading to longer waits or the need to find alternative locations.
3. Pay-As-You-Go Flexibility
Public charging offers a pay-as-you-go model, which can be handy if you only need occasional top-ups. For people who don’t drive daily or have unpredictable charging needs, public stations might suit their lifestyle. But for those who rely heavily on their EV, the costs of frequent public charging can add up quickly.
Which Option is More Affordable?
For most London EV drivers, home charging is the more affordable option in the long run, especially if you take advantage of off-peak tariffs and government grants for charger installation. Charging at home offers lower per-kWh costs, the convenience of charging overnight, and peace of mind knowing that your car will be ready when you need it.
However, if you live in a flat or don’t have access to off-street parking, public stations may be your only option. In this case, it’s best to familiarise yourself with the network of public chargers around London and try to plan your charging sessions during times when rates are lower, or you can use free charging points available in certain locations.
The Hybrid Approach
Many EV owners in London use a combination of both home and public charging, depending on their daily routine and driving habits. This hybrid approach can provide the flexibility of fast top-ups at public stations when needed, while keeping overall costs low with regular home charging.
Conclusion
Ultimately, the affordability of home charging versus public charging depends on your personal circumstances, including where you live, how often you drive, and how far you typically travel. If you have the option to install a home charger, it is generally the most cost-effective and convenient solution. For those relying on public charging, smart planning can help minimise costs while still enjoying the benefits of driving an electric vehicle.
As London continues to expand its EV infrastructure, the future of electric vehicle charging looks brighter and more accessible than ever, making it easier for residents to choose the option that works best for them.
