What’s the Difference Between Single Phase and Three Phase EV Charging Cables?
Choosing the right EV charging cable isn’t just about plug type – it’s also about power and speed. The key decision many UK EV drivers face is whether to go for a single-phase (1P) or three-phase (3P) cable. But what do these terms really mean, and how do they affect your charging experience?
In this guide, we break down everything you need to know to help you decide which cable type best suits your driving lifestyle and charging needs.

EV Charging Speeds Explained
EV charging cables vary based on the type of current they deliver and how many electrical phases they utilise:
-
Single-Phase (1P) Cables: Typically provide power output up to 7.4kW. These are most common in UK homes.
-
Three-Phase (3P) Cables: Can deliver up to 22kW, ideal for commercial or high-speed home charging setups.
| Feature | 1-Phase Cable (1P) | 3-Phase Cable (3P) |
|---|---|---|
| Power Output | Up to 7.4kW | Up to 22kW |
| Charging Time | Fast | Faster |
| Home Compatibility (UK) | Widely compatible | Requires 3-phase power supply |
| Ideal Use | Overnight home charging | Faster public or fleet charging |
Which Cable Is Right for You?
Choose a Single-Phase (1P) Cable if:
-
You’re mostly charging at home using a standard wall box.
-
Your vehicle doesn’t support 3-phase charging.
-
You want a budget-friendly, widely compatible option.
Choose a Three-Phase (3P) Cable if:
-
Your property or workplace has a three-phase power supply.
-
You drive a long-range EV or frequently need faster top-ups.
-
You often use public charge points with high-speed capabilities.

Real Charging Speeds: What to Expect
-
7kW (1P wall box): Around 6-8 hours to fully charge most EVs.
-
22kW (3P wall box or public): 3-5 hours for a full charge.
Remember, actual charging times also depend on your car’s onboard charger capacity.
