Introduction: Why Charger Type Matters
With more drivers making the switch to electric vehicles, understanding the different types of EV chargers UK drivers have access to has become essential knowledge. Choosing the right charger for your home or business directly affects how quickly you can charge, how much you’ll pay, and whether the charger will work with your vehicle.
This comprehensive guide explains every type of EV charger available in the UK, from slow home chargers to ultra-rapid public charging stations. We’ll help you understand the differences so you can make an informed decision about home charging or know what to look for when charging on the road.
Understanding Charging Speeds: What Do kW Ratings Mean?
Before diving into charger types, it’s important to understand how charging speed is measured. EV charger output is measured in kilowatts (kW) – the higher the number, the faster your car charges.
How Charging Speed Affects Your Life
To put these numbers in perspective, here’s how long it takes to add 100 miles of range to a typical EV:
- 3.7kW charger: Approximately 8-10 hours
- 7kW charger: Approximately 4-5 hours
- 22kW charger: Approximately 1-2 hours
- 50kW rapid charger: Approximately 30-40 minutes
- 150kW ultra-rapid charger: Approximately 10-15 minutes
For most home users, overnight charging at 7kW is perfect – you plug in when you get home, and wake up to a full battery. But understanding all options helps you make the right choice for your circumstances.
Home EV Charger Types
Home charging accounts for around 80% of all EV charging in the UK. Here are the main options:
3.7kW Single-Phase Charger
The slowest dedicated home charger option, 3.7kW units are becoming less common but still have their place.
Pros:
- Lower installation cost
- Less demand on your electrical supply
- Sufficient for low-mileage drivers
- Compatible with all UK properties
Cons:
- Very slow charging (10-14 hours for a full charge)
- May not fully charge larger batteries overnight
- Fewer models available
Best for: Drivers with small battery EVs, very low daily mileage, or properties with limited electrical capacity.
7kW Single-Phase Charger (Most Popular)
The 7kW charger is the UK’s most popular home charging solution, striking the perfect balance between speed, cost, and practicality.
Pros:
- Charges most EVs from empty to full overnight
- Works with standard UK single-phase electricity supply
- Wide range of models and brands available
- Eligible for OZEV grant (where applicable)
- Reasonable installation cost
Cons:
- Slower than three-phase options
- May take 8-12 hours for large battery EVs
Best for: The vast majority of UK homeowners. If you’re unsure, 7kW is almost certainly the right choice.
22kW Three-Phase Charger
For those who need faster home charging, 22kW chargers offer significantly improved speeds – but there’s a catch.
Pros:
- Three times faster than 7kW charging
- Ideal for high-mileage drivers
- Great for businesses with fleet vehicles
- Future-proofed as battery sizes increase
Cons:
- Requires three-phase electricity supply (most UK homes don’t have this)
- Upgrading to three-phase can cost £3,000-5,000+
- Some EVs can’t charge above 11kW on AC anyway
- Higher charger and installation costs
Best for: Commercial premises, properties already with three-phase supply, or high-mileage drivers who need midday top-ups.
Tethered vs Untethered Chargers
One of the first decisions when choosing a home charger is whether to go tethered or untethered.
Tethered Chargers
Tethered chargers have a permanently attached cable, like a petrol pump.
Advantages:
- Convenient – just grab the cable and plug in
- No cable to store or carry
- No risk of forgetting your cable elsewhere
- Slightly faster to connect
Disadvantages:
- Cable is always visible on the unit
- If the cable is damaged, the whole unit may need repair
- Cable connector must match your car (usually Type 2)
- If you change to a car with different connector, the charger needs replacing
Untethered Chargers (Socketed)
Untethered chargers have a socket where you plug in your own cable.
Advantages:
- Cleaner appearance when not in use
- Use any compatible cable
- Cable damage doesn’t affect the charger
- More flexible if you change vehicle
Disadvantages:
- Need to store and connect cable each time
- Must carry cable if charging away from home
- Marginally more hassle to connect
Our recommendation: For most home users, tethered chargers offer the best convenience. Untethered makes sense if you have multiple EVs with different connectors or prefer a tidier installation.

Frequently Asked Questions
Can I use a three-pin plug to charge my EV?
Yes, most EVs come with a three-pin charging cable for emergencies. However, charging at 2.3kW is very slow (15-20+ hours for a full charge) and not recommended for regular use. Dedicated chargers are much safer and faster.
Will a 7kW charger work with my car?
Yes. 7kW chargers work with all EVs sold in the UK (Type 2 connector). Your car’s onboard charger determines the actual charging speed – if your car only accepts 3.7kW, it will charge at that rate even on a 7kW charger.
Do I need planning permission for an EV charger?
Usually no. EV charger installation is typically permitted development. However, listed buildings, conservation areas, and some flat conversions may need approval. Your installer can advise.
Can I install an EV charger myself?
No. EV charger installation must be carried out by a qualified, Part P registered electrician. The work must be notified to Building Control and certified. DIY installation would be illegal and dangerous.
