The Ultimate Guide to Charging an Electric Car

Charging is the part of EV ownership that puts off more people than it should. In reality, it's simpler than filling up with petrol – and a lot cheaper too.

This guide covers everything you need to know about electric vehicle charging on the public network: the different types of EV charger, how fast each one is, how to plug in and pay at a public electric vehicle charging station, what it costs, and how the best EV charging UK networks stack up.

• There are now over 121,000 public EV chargers across more than 46,000 UK locations – up by almost half in just two years.
• Rapid and ultra-rapid electric vehicle chargers can add around 100 miles of range in as little as 20–30 minutes.
• Every newly installed public EV charging unit above 8kW must legally accept contactless card payment – no membership or app required.

How Does Electric Car Charging Work?

Charging an electric car or plug-in hybrid means connecting it to a power source via a charging cable – similar in principle to plugging in any other appliance, just delivering far more energy. The charging port is usually located at the front of the car or in roughly the same spot you'd expect to find a fuel filler cap.

There are two main ways to charge electric car batteries: at home using a dedicated wallbox or a three-pin socket, or on the public network. Thousands of charging points for electric cars are found at supermarkets, car parks, motorway services, and increasingly on residential streets.

Around 80% of UK EV drivers charge at home at least some of the time. Public EV charging stations cover the rest – top-ups, longer trips, and situations where home charging isn't an option. If you're new to EVs altogether, our complete guide to electric vehicles is a good starting point on the basics.

Types of EV Charger – And How Fast They Really Are

Charging speed is measured in kilowatts (kW) – the higher the number, the faster the battery fills up. Public EV chargers generally fall into four speed bands.

EV Charger Types, Power Output, and Typical Charge Times

_{*Charge times vary by vehicle, battery size, and the car's maximum charging rate – not every EV can accept the full power a charger offers.}

Slow and fast EV chargers use alternating current (AC) and suit situations where you're parked for a while anyway – shopping, working, or staying overnight. Rapid and ultra-rapid electric vehicle chargers use direct current (DC) and are built for speed: get in, charge to around 80%, and get back on the road.

Charging slows down noticeably past that point to protect the battery, which is why most rapid-charging stops are timed around 80% rather than a full charge.

How to Use a Public EV Charging Station: Step by Step

If you've never used a public EV car charging station before, the process is far more straightforward than it looks.

1. Find a charging station. Download Zap-Map (or PlugShare) before you set off – it's the go-to app for electric car charging, showing live availability on a charging station map so you can spot electric charging points near you in seconds. Most modern sat nav systems include charger locations too, and many EVs will suggest a stop automatically when the battery gets low. Alternatively, you can also visit our dedicated webpage displaying the EV car charging points UK map.
2. Park and connect. Pull into the bay, switch off, and open your charging port. Public rapid and ultra-rapid charging stations almost always come with their own tethered cable. For some slow and fast chargers, you'll need your own electric car charging cable – a Type 2 is the standard for most modern EVs, so keep one in the boot.
3. Start the session and pay. Tap your contactless card or phone, or use the network's app or RFID card if you have one. Under UK regulations, every public EV charging unit rated above 8kW (and installed after 2024) must offer contactless payment without requiring an account first.
4. Monitor and unplug. Charging status shows on the unit itself, your car's dashboard, or the relevant app. Once you've reached your target charge, end the session, disconnect, and stow the electric car charger cable before driving off.

Publicrapid and ultra-rapid EV charging stations are increasingly grouped into charging hubs – locations with eight or more high-powered EV chargers, often with cafés or shops nearby. According to Zapmap's most recent annual driver survey, hubs have now overtaken motorway services as the most popular place to charge on longer journeys.

The UK's Major Public EV Charging Networks

There's no shortage of choice when it comes to UK EV charging. The electric charging points UK network has grown past 121,000 across more than 46,000 locations, and ultra-rapid charging – the fastest-growing segment – is leading that expansion.

Among the largest and most established networks:

• Tesla Supercharger – now open to all EVs, not just Teslas, and rated the UK's best large rapid/ultra-rapid network for driver satisfaction two years running.
• InstaVolt – one of the most widely used rapid networks, found at retail parks and roadside locations nationwide.
• GRIDSERVE Electric Highway – a major presence at motorway services, including dedicated Electric Forecourts.
• MFG EV Power – fast-expanding hubs at fuel forecourts and supermarkets, including Morrisons.
• Osprey – consistently well-rated for reliability and ease of use, often found at pubs and retail locations.
• Pod Point – one of the UK's largest networks by total charger count, with destination EV charging units concentrated at supermarkets and retail car parks.
• Ionity – ultra-rapid charging at motorway and retail locations, with strong growth over the past year.
• BP Pulse – a long-established operator with a significant share of the rapid and ultra-rapid charging points UK, found at retail and roadside sites nationwide.
• Sainsbury's Smart Charge – the top-rated network in Zapmap's medium category, with rapid hubs at supermarket car parks.

You don't need an account with every network. Roaming services such as Octopus Electroverse (also available as an Octopus EV charger RFID card) let you pay across multiple charge points for electric cars from one app. UK law now requires every network to support at least one third-party roaming provider, so you're never locked out for not having the right app.

The Cost of Charging Electric Cars in Public

Public electric car charging costs more than charging at home, and the exact price depends on charger speed and network. The table below gives a current snapshot of EV charging cost by type.

EV Charging Cost Comparison: Public vs Home

_{*Figures approximate, based on the Zapmap Price Index and Ofgem price cap at time of writing. Cost per mile assumes average EV efficiency of around 3.5 miles per kWh. Public charging prices vary by network and location and change regularly.}

Several networks offer cheaper rates to members or app users than their pay-as-you-go price. Check before a long trip if you use the same network regularly. Many supermarkets, car parks, attraction spots and workplaces also offer free EV car charging as an incentive for visitors and staff – particularly useful on shorter stops.

Home Charging vs Public Electric Vehicle Charging: Which Should You Use?

Most EV owners use both. The real question is how to split your EV charging to keep costs down and journeys stress-free.

Home Charging vs Public EV Charging: Key Differences

If you have off-street parking, a home car charging station should handle the bulk of your electric car charge at home. It's significantly cheaper, especially on an EV-specific tariff, and means you're rarely starting the day with less than a full battery. Public EV charging then comes into play for journeys beyond your EV's comfortable range, or as your main charging method if a home setup isn't an option.

A significant number of UK EV drivers don't have access to home EV charging and rely on the public network, including on-street and destination charging points, for most of their needs - and confidence in public charging has grown considerably as the network has expanded.

Tips for Stress-Free Public EV Charging on a Long Journey

• Plan your stops around rapid or ultra-rapid chargers if you're covering serious distance – they'll save significant time over slower EV charging units.
• Charge to around 80%, not 100%, on rapid chargers. Speed drops sharply after that point and the extra wait rarely makes sense.
• Use the Zap-Map EV charging map to check live availability before you arrive, particularly at busy times or popular service stations.
• Keep a backup payment method. Contactless is mandatory on new charging station EV units above 8kW, but a network app on your phone covers any edge cases.
• Build in a buffer. EV range varies with weather, motorway speeds, and load – don't plan a journey around your absolute maximum range.
