The Complete Guide to EV Charging: Everything You Need to Know

Simplifying motoring with a switch to electric? That's the plan, yet many drivers feel overwhelmed by charging types, connector confusion, and network pricing that seems to change weekly.

In this guide, we will cover what actually matters in the UK including real costs, safety warnings you need to know, and practical decisions that will save you money and hassle.


UK Connector Types

Type 2 (AC Connector)

Type 2 is the standard AC connector used across the UK and Europe. It handles slow to medium-speed charging at home, workplaces, and destination locations.

Every new electric car sold in the UK comes with a Type 2 port. This seven-pin connector can deliver up to 22kW, though most home installations use 7kW.

You'll find Type 2 connectors at shopping centres, hotels, car parks, and on-street charging points throughout the UK.

AC CONNECTOR TYPES

CCS2 (DC Fast Connector)

CCS2 (Combined Charging System 2) adds two extra pins below the Type 2 connector for DC fast charging. It's the European standard for rapid charging.

This connector handles everything from 50kW rapid charging up to 350kW+ ultra-rapid speeds. All new EVs sold in the UK include CCS2 capability.

CCS2 chargers are found at motorway services, charging hubs, and major retail locations across the country.

CHAdeMO (Legacy Connector)

CHAdeMO is a Japanese DC fast charging standard that's being phased out in the UK. Only the  older Nissan Leaf and some Japanese vehicles use this connector.

New EVs no longer come with CHAdeMO ports. The connector is larger and less efficient than CCS2.

If you own a CHAdeMO vehicle, check charging locations carefully as fewer new installations include this connector type.

Tesla Connector (Europe)

Tesla vehicles sold in Europe use the standard CCS2 connector, unlike Tesla's proprietary system in America.

This means Tesla cars can charge at any CCS2 charging point, and other EVs can use Tesla Superchargers with the right payment method.

Tesla's approach in Europe eliminates compatibility issues and simplifies charging for all drivers.


Charging Speeds Explained

Slow Charging (3-7kW)

Slow charging uses AC power and works through your car's onboard charger. A 3kW connection provides 12-15 miles of range per hour.

Most UK homes can install 7kW charging, giving 25-35 miles per hour. This covers daily driving needs for most people.

Fast Charging (7-22kW)

Fast AC charging is perfect for destination stops. Shopping centres and workplaces typically offer 7-22kW charging speeds.

These speeds provide 25-80 miles of range per hour, ideal for topping up whilst you're doing something else.

Rapid Charging (50-150kW)

Rapid DC charging bypasses your car's onboard charger to deliver power directly to the battery. 50kW provides meaningful charging in 30-45 minutes.

150kW chargers can add 10-80% charge in 15-20 minutes for most modern EVs. This covers nearly all rapid charging needs.

Rapid charging works best when your battery is below 80%. Charging speed reduces significantly above this level.

Ultra-Rapid Charging (150kW+)

Ultra-rapid chargers offer 150kW to 350kW+ speeds, though few cars can actually use the maximum power available.

Even cars that support ultra-rapid charging only achieve peak speeds briefly, usually when the battery is nearly empty.

These chargers are expensive to use but essential for long-distance travel on busy routes.


Types of Chargers

Home Chargers

Home chargers typically provide 7kW AC charging through a dedicated wall-mounted unit. They use Type 2 connectors and require professional installation.

Smart home chargers can schedule charging during cheap electricity periods and integrate with solar panels for maximum savings.

Tethered units include built-in cables, whilst untethered units require you to provide your own charging cable.

Workplace Chargers

Workplace chargers usually offer 7-22kW AC charging, perfect for topping up during the working day.

Many employers provide free charging as a staff benefit. Others charge at cost or slightly above to cover electricity expenses.

Workplace charging reduces reliance on expensive public rapid charging for daily driving needs.

Destination Chargers

Destination chargers are found at hotels, shopping centres, restaurants, and leisure facilities. They typically provide 7-22kW AC charging.

Many supermarkets offer free charging to attract customers. Cinema car parks increasingly provide charging during film screenings.

These chargers work perfectly for activities lasting 1-3 hours, providing useful range whilst you're occupied elsewhere.

Public AC Chargers

Public AC chargers include on-street posts, car park units, and community charging hubs. They typically offer 7-22kW charging speeds.

Payment methods vary from contactless cards to smartphone apps and RFID cards. Pricing ranges from free to 50p+ per kWh.

Reliability can be inconsistent, so always have backup charging locations planned for important journeys.

Rapid DC Chargers

Rapid chargers are found at motorway services, retail parks, and dedicated charging hubs. They provide 50-150kW DC charging.

These chargers are essential for long-distance travel but expensive for regular use. Expect to pay 40p-80p per kWh.

Tesla Superchargers offer excellent reliability but charge premium prices. Now open to all EVs with CCS2 connectors.

Ultra-Rapid Chargers

Ultra-rapid chargers provide 150kW+ speeds at motorway services and major charging hubs. They're the fastest option available.

Ionity and Gridserve focus on ultra-rapid charging but charge premium prices. Expect £0.69-£0.79 per kWh without subscriptions.

These chargers are essential for busy routes during peak periods but overkill for most charging needs.

Safety Requirements

Professional Installation

Never attempt DIY electrical work for EV charging. Only Part P certified electricians should install home chargers.

All installations must comply with BS 7671 wiring regulations. This isn't optional - it's legally required for safety and insurance.

Installation certificates provide legal protection and insurance validation. Keep these documents safe for house sales and claims.

Fire Safety Considerations

EV charging points require careful positioning away from combustible materials. Zurich Insurance recommends 10 metres from combustible walls.

Underground charging needs enhanced fire detection systems. Lithium battery fires burn extremely hot and produce toxic gases.

Commercial installations must comply with the Regulatory Reform (Fire Safety) Order 2005, requiring proper risk assessments.

Electrical Safety

Proper earth bonding and RCD protection are essential for all installations. Verify adequate cable ratings for the charging load.

Regular inspection of cables and connections prevents dangerous faults. Report any damage immediately to qualified professionals.

Know how to safely disconnect charging in emergencies. Keep appropriate fire extinguishers nearby for electrical fires.

Adapter Safety

Cheap adapters can kill. Only buy adapters from reputable suppliers with proper certifications.

Tesla's official CCS adapter costs £200+ but includes proper safety systems. Cheaper alternatives often lack protection circuits.

CE marking alone isn't sufficient - verify genuine product certification before using any charging adapter.


Real Costs

Home Charging Costs

Economy 7 tariffs provide overnight electricity at 7p-15p per kWh. Standard rates reach 25p-35p per kWh during peak hours.

Octopus Energy offers EV-specific tariffs with rates under 3p per mile for overnight charging. Smart chargers maximise these savings.

Home charging typically costs half the price of petrol for equivalent journeys. This represents the biggest EV advantage.

Public Charging Costs

Zapmap data shows rapid charging averages 76p per kWh. That's roughly 23 pence per mile for typical EVs.

Tesla Superchargers charge 40p-60p per kWh, making them cheaper than most alternatives. Reliability justifies the premium.

Destination charging varies wildly from free (many supermarkets) to 50p+ per kWh at premium locations.

Hidden Costs

Overstay fees catch drivers unexpectedly. Networks charge £10-£20 per hour after charging completes.

RFID cards cost £2-£5 each but provide cheaper rates than contactless payments. Regular users benefit from network subscriptions.

Connection fees on some networks add £1-£2 per session regardless of energy consumed.

Cost Comparison by Type

Charging Type Cost
Home charging 8p per mile (with cheap-rate tariff)
Destination charging 10p-20p per mile
Rapid charging 20p-25p per mile
Petrol equivalent 13p-17p per mile

Which Type to Choose

For Daily Driving

Install a 7kW smart home charger for daily needs. This covers most driving without expensive electrical upgrades.

Tethered chargers prove more convenient than untethered options. Built-in cables eliminate wrestling with heavy connectors.

Smart charging features enable automatic overnight charging during cheap-rate periods, halving your charging costs.

For Workplace Charging

Use workplace charging when available to reduce reliance on expensive public charging. Many employers provide this free.

Combine workplace and home charging to minimise public charging costs. This covers most weekly driving needs.

Don't rely solely on workplace charging - always have home backup options available.

For Long-Distance Travel

Rapid charging works best for journeys over 150 miles. Plan stops at reliable networks like Tesla or Gridserve.

Charge before you need to rather than waiting until nearly empty. This provides more options and reduces stress.

Always have backup charging locations planned. Primary chargers fail unexpectedly during peak periods.

For Urban Drivers

On-street charging suits drivers without home parking. Char.gy and other networks expand lamp post charging.

Combine on-street charging with destination charging for shopping and leisure activities.

Consider rapid charging for weekly top-ups if on-street options aren't sufficient for daily needs.

Cost Management Strategy

Avoid rapid charging unless necessary. Home charging costs 8p per mile whilst rapid charging hits 23p per mile. (We have heard of some home-charging tariffs being as little as 3p per mile).

Network subscriptions benefit regular users. Monthly fees typically cost £7-£15 but provide significant per-kWh savings.

Use apps like Zap-Map to find cheapest charging options and avoid overstay fees through real-time monitoring.


Final Recommendations

Essential Equipment

Every EV driver needs a reliable Type 2 charging cable for public AC charging. Buy quality cables with proper certification.

Download Zap-Map for real-time charging point availability and pricing - essential for journey planning and cost management.

Consider a Tesla CCS adapter if you don't drive a Tesla. Provides access to the most reliable rapid charging network.

Key Safety Points

Only use certified electricians for installation work. Verify they specifically understand EV charging requirements.

Inspect charging equipment regularly and report damage immediately. Don't use damaged cables or connectors.

Understand emergency disconnection procedures and keep appropriate fire safety equipment nearby.

Future-Proofing

800V vehicle architecture enables faster charging speeds. Consider this when choosing your next EV.

Install appropriate electrical capacity for future upgrades. Adding circuits later costs more than initial installation.

The UK charging network expands rapidly. What seems limited today will improve significantly over coming years.

Understanding these fundamentals ensures you benefit from cleaner, cheaper motoring whilst staying safe and compliant with all requirements.
