Electric Vehicle Charging: The Complete Guide
Everything you need to know about charging your EV in the UK
If you're considering making the switch to electric, or you've already taken the plunge, understanding how to charge your vehicle efficiently is crucial. At Sell Or Switch, we believe in cutting through the jargon to give you the facts that matter.
Cal—our data-driven mascot who lives and breathes vehicle economics—has crunched the numbers on EV charging costs, speeds, and practicalities. Whether you're charging at home or using the growing network of public charge points across the UK, this guide covers everything you need to make informed decisions about powering your electric vehicle.
Home Charging: Your Primary Option
The vast majority of EV owners do most of their charging at home. It's the most cost-effective and convenient method, with two main options available depending on your setup and requirements.
1. Dedicated Home Charge Point
This is the standard charging solution for UK EV owners. A dedicated wall-mounted unit offers significantly faster charging than a domestic socket and includes built-in safety features.
| Specification | Details |
|---|---|
| Power Output | Typically 7.4 kW (single-phase domestic supply) |
| Charging Speed | Adds approximately 20-30 miles of range per hour, depending on vehicle battery capacity and efficiency |
| Installation Requirements | Must be installed by a qualified electrician certified for EV charge point installation. Government grants may be available to offset costs. |
| Prerequisites | Requires off-road parking such as a driveway or dedicated parking space. Cables cannot trail across pavements or public areas. |
2. Standard Domestic Socket (Emergency Use Only)
While most EVs come with a cable that plugs into a standard three-pin socket, this method should be considered a backup option rather than a primary charging solution.
Power Output: Limited to 2.3 kW due to the constraints of domestic wiring.
Charging Speed: Approximately 5-10 miles of range per hour, making it impractical for regular use.
Best Use Case: Topping up overnight when you only need a small amount of charge, or emergency situations where no other option is available.
Safety Note: Always plug directly into the wall socket. Extension leads are not rated for sustained high-current draw and present a fire risk.
Location Requirements: Must still have secure off-road parking to prevent cables crossing public footpaths.
Public Charging Network
The UK now has over 50,000 public charge points across motorway services, supermarkets, retail parks, and on-street locations. Understanding the different charging speeds and cost structures will help you plan your journeys more effectively.
Understanding Public Charging Costs
Pricing Structure: Public charging typically costs more than home charging, reflecting the infrastructure investment and convenience factor. Prices vary significantly between operators and locations.
Network Operators: Multiple providers operate across the UK, including Gridserve, BP Pulse, Ionity, Tesla Supercharger (now open to non-Tesla vehicles), and Pod Point. Each has its own pricing structure.
Membership Benefits: Many networks offer subscription plans that provide discounted per-kWh rates if you charge frequently. Compare costs if you're a regular user of public infrastructure.
Payment Methods: Most modern charge points accept contactless payment, while others require network-specific apps or RFID cards.
Charging Speed Categories
| Category | Power Output | Typical Locations | Charging Time (10-80%) |
|---|---|---|---|
| Ultra Rapid DC | 150-350 kW | Motorway service stations, dedicated charging hubs near major routes, select retail locations | 20-35 minutes for most modern EVs. Latest generation vehicles can add 100+ miles in under 10 minutes. |
| Rapid DC | 50-150 kW | Supermarket car parks, retail parks, service stations, leisure centres | 45-75 minutes depending on battery size and state of charge |
| Fast AC | 7-22 kW | Public car parks, workplace charging, destination charging at hotels and restaurants | 3-8 hours for a full charge. Ideal for extended parking periods. |
| Slow AC | 3-7 kW | On-street residential charging, some public car parks | 6-12 hours. Similar to home charging speeds. |
Temperature Considerations: Battery performance is affected by temperature. In cold weather, charging speeds (particularly rapid DC charging) may be reduced as the battery management system protects cells from damage. Pre-conditioning your battery while still connected to a charger can help optimize charging speed on your next stop.
